====================
Netfilter/IPVS fixes for net

The following patchset contains Netfilter fixes for your net tree,
they are:

1) Put back reference on CLUSTERIP configuration structure from the
   error path, patch from Florian Westphal.

2) Put reference on CLUSTERIP configuration instead of freeing it,
   another cpu may still be walking over it, also from Florian.

3) Refetch pointer to IPv6 header from nf_nat_ipv6_manip_pkt() given
   packet manipulation may reallocation the skbuff header, from Florian.

4) Missing match size sanity checks in ebt_among, from Florian.

5) Convert BUG_ON to WARN_ON in ebtables, from Florian.

6) Sanity check userspace offsets from ebtables kernel, from Florian.

7) Missing checksum replace call in flowtable IPv4 DNAT, from Felix
   Fietkau.

8) Bump the right stats on checksum error from bridge netfilter,
   from Taehee Yoo.

9) Unset interface flag in IPv6 fib lookups otherwise we get
   misleading routing lookup results, from Florian.

10) Missing sk_to_full_sk() in ip6_route_me_harder() from Eric Dumazet.

11) Don't allow devices to be part of multiple flowtables at the same
    time, this may break setups.

12) Missing netlink attribute validation in flowtable deletion.

13) Wrong array index in nf_unregister_net_hook() call from error path
    in flowtable addition path.

14) Fix FTP IPVS helper when NAT mangling is in place, patch from
    Julian Anastasov.

      rds: Incorrect reference counting in TCP socket creation · 84eef2b2
      Ka-Cheong Poon authored 
      Commit 0933a578 ("rds: tcp: use sock_create_lite() to create the
accept socket") has a reference counting issue in TCP socket creation
when accepting a new connection.  The code uses sock_create_lite() to
create a kernel socket.  But it does not do __module_get() on the
socket owner.  When the connection is shutdown and sock_release() is
called to free the socket, the owner's reference count is decremented
and becomes incorrect.  Note that this bug only shows up when the socket
owner is configured as a kernel module.

v2: Update comments

Fixes: 0933a578 ("rds: tcp: use sock_create_lite() to create the accept socket")

====================
pull-request: bpf 2018-02-28

The following pull-request contains BPF updates for your *net* tree.

The main changes are:

1) Add schedule points and reduce the number of loop iterations
   the test_bpf kernel module is performing in order to not hog
   the CPU for too long, from Eric.

2) Fix an out of bounds access in tail calls in the ppc64 BPF
   JIT compiler, from Daniel.

3) Fix a crash on arm64 on unaligned BPF xadd operations that
   could be triggered via interpreter and JIT, from Daniel.

Please not that once you merge net into net-next at some point, there
is a minor merge conflict in test_verifier.c since test cases had
been added at the end in both trees. Resolution is trivial: keep all
the test cases from both trees.

      vrf: check forwarding on the original netdevice when generating ICMP dest unreachable · e2c0dc1f
      Stephen Suryaputra authored 
      When ip_error() is called the device is the l3mdev master instead of the
original device. So the forwarding check should be on the original one.

Changes from v2:
- Handle the original device disappearing (per David Ahern)
- Minimize the change in code order

Changes from v1:
- Only need to reset the device on which __in_dev_get_rcu() is done (per
  David Ahern).

      net: allow interface to be set into VRF if VLAN interface in same VRF · 50d629e7
      Mike Manning authored 
      Setting an interface into a VRF fails with 'RTNETLINK answers: File
exists' if one of its VLAN interfaces is already in the same VRF.
As the VRF is an upper device of the VLAN interface, it is also showing
up as an upper device of the interface itself. The solution is to
restrict this check to devices other than master. As only one master
device can be linked to a device, the check in this case is that the
upper device (VRF) being linked to is not the same as the master device
instead of it not being any one of the upper devices.

The following example shows an interface ens12 (with a VLAN interface
ens12.10) being set into VRF green, which behaves as expected:

  # ip link add link ens12 ens12.10 type vlan id 10
  # ip link set dev ens12 master vrfgreen
  # ip link show dev ens12
    3: ens12: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc fq_codel
       master vrfgreen state UP mode DEFAULT group default qlen 1000
       link/ether 52:54:00:4c:a0:45 brd ff:ff:ff:ff:ff:ff

But if the VLAN interface has previously been set into the same VRF,
then setting the interface into the VRF fails:

  # ip link set dev ens12 nomaster
  # ip link set dev ens12.10 master vrfgreen
  # ip link show dev ens12.10
    39: ens12.10@ens12: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500
    qdisc noqueue master vrfgreen state UP mode DEFAULT group default
    qlen 1000 link/ether 52:54:00:4c:a0:45 brd ff:ff:ff:ff:ff:ff
  # ip link set dev ens12 master vrfgreen
    RTNETLINK answers: File exists

The workaround is to move the VLAN interface back into the default VRF
beforehand, but it has to be shut first so as to avoid the risk of
traffic leaking from the VRF. This fix avoids needing this workaround.
