This patch adds getsockopt(SOL_NETLINK, NETLINK_LIST_MEMBERSHIPS) to
retrieve all groups a socket is a member of. Currently, we have to use
getsockname() and look at the nl.nl_groups bitmask. However, this mask is
limited to 32 groups. Hence, similar to NETLINK_ADD_MEMBERSHIP and
NETLINK_DROP_MEMBERSHIP, this adds a separate sockopt to manager higher
groups IDs than 32.

This new NETLINK_LIST_MEMBERSHIPS option takes a pointer to __u32 and the
size of the array. The array is filled with the full membership-set of the
socket, and the required array size is returned in optlen. Hence,
user-space can retry with a properly sized array in case it was too small.

Netfilter updates for net-next

The following patchset contains a final Netfilter pull request for net-next
4.2. This mostly addresses some fallout from the previous pull request, small
netns updates and a couple of new features for nfnetlink_log and the socket
match that didn't get in time for the previous pull request. More specifically
they are:

1) Add security context information to nfnetlink_queue, from Roman Kubiak.

2) Add support to restore the sk_mark into skb->mark through xt_socket,
   from Harout Hedeshian.

3) Force alignment of 16 bytes of per cpu xt_counters, from Eric Dumazet.

4) Rename br_netfilter.c to br_netfilter_hooks.c to prepare split of IPv6 code
   into a separated file.

5) Move the IPv6 code in br_netfilter into a separated file.

6) Remove unused RCV_SKB_FAIL() in nfnetlink_queue and nfetlink_log, from Eric
   Biederman.

7) Two liner to simplify netns logic in em_ipset_match().

8) Add missing includes to net/net_namespace.h to avoid compilation problems
   that result from not including linux/netfilter.h in netns headers.

9) Use a forward declaration instead of including linux/proc_fs.h from
   netns/netfilter.h

10) Add a new linux/netfilter_defs.h to replace the linux/netfilter.h inclusion
    in netns headers.

11) Remove spurious netfilter.h file included in the net tree, also from Eric
    Biederman.

12) Fix x_tables compilation warnings on 32 bits platforms that resulted from
    recent changes in x_tables counters, from Florian Westphal.

This pulls the full hook netfilter definitions from all those that include

Instead let's just include the bare minimum required in the new

this compilation error:

xt_socket is useful for matching sockets with IP_TRANSPARENT and
taking some action on the matching packets. However, it lacks the
ability to match only a small subset of transparent sockets.

Suppose there are 2 applications, each with its own set of transparent
sockets. The first application wants all matching packets dropped,
while the second application wants them forwarded somewhere else.

Add the ability to retore the skb->mark from the sk_mark. The mark
is only restored if a matching socket is found and the transparent /
nowildcard conditions are satisfied.

Now the 2 hypothetical applications can differentiate their sockets
based on a mark value set with SO_MARK.

iptables -t mangle -I PREROUTING -m socket --transparent \
                                           --restore-skmark -j action
iptables -t mangle -A action -m mark --mark 10 -j action2
iptables -t mangle -A action -m mark --mark 11 -j action3

Jeff Kirsher says:

====================
This series contains updates to fm10k only.

Alex provides two fixes for the fm10k, first folds the fm10k_pull_tail()
call into fm10k_add_rx_frag(), this way the fragment does not have to be
modified after it is added to the skb.  The second fixes missing braces
to an if statement.

The remaining patches are from Jacob which contain improvements and fixes
for fm10k.  First fix makes it so that invalid address will simply be
skipped and allows synchronizing the full list to proceed with using
iproute2 tool.  Fixed a possible kernel panic by using the correct
transmit timestamp function.  Simplified the code flow for setting the
IN_PROGRESS bit of the shinfo for an skb that we will be timestamping.
Fix a bug in the timestamping transmit enqueue code responsible for a
NULL pointer dereference and invalid access of the skb list by freeing
the clone in the cases where we did not add it to the queue.  Update the
PF code so that it resets the empty TQMAP/RQMAP regirsters post-VFLR to
prevent innocent VF drivers from triggering malicious driver events.
The SYSTIME_CFG.Adjust direction bit is actually supposed to indicate
that the adjustment is positive, so fix the code to align correctly with
the hardware and documentation.  Cleanup local variable that is no longer
used after a previous refactor of the code.  Fix the code flow so that we
actually clear the enabled flag as part of our removal of the LPORT.
