But there are many more, resulting in the machine going OOM after some
days.

From looking at the TPROXY code, and with help from Florian, I see
that the memory leak is introduced in tcp_v4_early_demux():

  void tcp_v4_early_demux(struct sk_buff *skb)
  {
    /* ... */

    iph = ip_hdr(skb);
    th = tcp_hdr(skb);

    if (th->doff < sizeof(struct tcphdr) / 4)
        return;

    sk = __inet_lookup_established(dev_net(skb->dev), &tcp_hashinfo,
                       iph->saddr, th->source,
                       iph->daddr, ntohs(th->dest),
                       skb->skb_iif);
    if (sk) {
        skb->sk = sk;

where the socket is assigned unconditionally to skb->sk, also bumping
the refcnt on it.  This is problematic, because in our case the skb
has already a socket assigned in the TPROXY target.  This then results
in the leak I see.

The very same issue seems to be with IPv6, but haven't tested.

It happens because in bond_ab_arp_probe() we change the flags of a slave
without holding the RTNL lock.

To fix this - remove the useless curr_active_lock, RCUify it and lock RTNL
while changing the slave's flags. Also, remove bond_ab_arp_probe() from
under any locks in bond_ab_arp_mon().

Currently we're calling it from under RCU context, however we're using some
functions that require rtnl to be held.

Fix this by restructuring the locking - don't call it under any locks,
aquire rcu_read_lock() if we're sending _only_ (i.e. we have the active
slave present), and use rtnl locking otherwise - if we need to modify
(in)active flags of a slave.

Currently bond_ab_arp_probe() is always called under rcu_read_lock(),
however to work with curr_active_slave we're still holding the
curr_slave_lock.

To remove that curr_slave_lock - rcu_dereference the bond's
curr_active_slave and use it further - so that we're sure the slave won't
go away, and we don't care if it will change in the meanwhile.

Submission d9aee591 "bnx2x: Don't release PCI bars on shutdown" separated
the PCI remove and shutdown flows, but pci_disable_device() is still
being called on both.
As a result, a dev_WARN_ONCE will be hit during shutdown for every bnx2x
VF probed on a hypervisor (as its shutdown callback will be called and later
pci_disable_sriov() will call its remove callback).

This calls the pci_disable_device() only on the remove flow.

Pull user namespaces work from Eric Biederman:
 "The work to convert the kernel to use kuid_t and kgid_t has been
  finished since 3.12 so it is time to remove the scaffolding that
  allowed the work to progress incrementally.

  The first patch on this branch just removes the scaffolding, ensuring
  we will always get compile errors if people accidentally try the
  userspace and the kernel uid and gid types.  The second patch an
  overlooked and unused chunk of mips code that that fails to build
  after the first patch.

  The code hasn't been in linux-next for long (as I was out of it and
  could not sheppared the cold properly) but the patch has been around
  for a long time just waiting for the day when I had finished the
  uid/gid conversions.  Putting the code in linux-next did find the
  compile failure on mips so I took the time to get that fix reviewed
  and included.  Beyond that I am not too worried about errors because
  all these two patches do is delete a modest amount of code"

Pull thermal management updates from Zhang Rui:
 "This time, the biggest change is the work of representing hardware
  thermal properties in device tree infrastructure.

  This work includes the introduction of a device tree bindings for
  describing the hardware thermal behavior and limits, and also a parser
  to read and interpret the data, and build thermal zones and thermal
  binding parameters.  It also contains three examples on how to use the
  new representation on sensor devices, using three different drivers to
  accomplish it.  One driver is in thermal subsystem, the TI SoC
  thermal, and the other two drivers are in hwmon subsystem.

  Actually, this would be the first step of the complete work because we
  still need to check other potential drivers to be converted and then
  validate the proposed API.  But the reason why I include it in this
  pull request is that, first, this change does not hurt any others
  without using this approach, second, the principle and concept of this
  change would not break after converting the remaining drivers.  BTW,
  as you can see, there are several points in this change that do not
  belong to thermal subsystem.  Because it has been suggested by Guenter
  R that in such cases, it is recommended to send the complete series
  via one single subsystem.

  Specifics:

   - representing hardware thermal properties in device tree
     infrastructure

   - fix a regression that the imx thermal driver breaks system suspend.

   - introduce ACPI INT3403 thermal driver to retrieve temperature data
     from the INT3403 ACPI device object present on some systems.

   - introduce debug statement for thermal core and step_wise governor.

   - assorted fixes and cleanups for thermal core, cpu cooling, exynos
     thrmal, intel powerclamp and imx thermal driver"
