Pull networking fixes from David Miller:

 1) Found via trinity:

    If you connect up an ipv6 socket to an ipv4 mapped address then an
    ipv6 one, sendmsg() can croak because ip6_sk_dst_check() assumes the
    route cached in the socket is an ipv6 one.  In this case there is an
    ipv4 route attached, so it gets stomped on.

    Reported by Dave Jones and Hannes Frederic Sowa, fixed by Eric
    Dumazet.

 2) AF_KEY notifications leak some kernel memory to userspace, fix from
    Mathias Krause.

 3) DLCI calls __dev_get_by_name() without proper locking, and dlci_del
    doesn't validate that the device being deleted is actually a DLCI
    one.  Fixes from Li Zefan.

 4) Length check on bluetooth l2cap information responses is wrong, each
    response type has a different lenth, so we should make sure it's in
    a given range rather than enforce one single valid length.  From
    Jaganath Kanakkassery.

 5) Receive FIFO overflow is really easy to trigger in stress scenerios
    in the sh_eth driver, but the event isn't being handled properly at
    all.  Specifically, the mask of error interrupts doesn't include the
    event so we never clear it, resulting in the driver becomming wedged
    processing an interrupt that never gets cleared.

    Fix from Sergei Shtylyov.

 6) qlcnic sleeps while holding a spinlock, use mdelay() instead of
    msleep().  From Shahed Shaikh.

 7) Missing curly braces causes SIP netfilter NAT module to always drop
    packets.  Fix from Balazs Peter Odor.

 8) ipt_ULOG in netfilter passes the wrong value to timer setup, causing
    the timer to dereference crap when it fires.  Fix from Gao Feng.

 9) Missing RCU protection around txq->axq_acq traversal in
    ath_txq_schedule().  Fix from Felix Fietkau.

10) Idle state transition test in ath9k_htc_config() is reversed, fix
    from Sujith Manoharan.

11) IPV6 forwarding handles unicast Router Alert packets incorrectly.
    It tests the wrong option state.  Previously opt->ra being non-zero
    indicated a router alert marking in the SKB, but now it's indicated
    by a bit in opt->flags.  Fix from YOSHIFUJI Hideaki.

12) SKB leak in GRE tunnel GSO handling, from Eric Dumazet.

13) get_user_pages_fast() error handling in TUN and MACVTAP use the same
    local variable for the base index and the loop iterator for page
    traversal, oops! Fix from Michael S Tsirkin.

14) ipv6_get_lladdr() can fail, and we must therefore check it's return
    value in inet6_set_iftoken().  For from Hannes Frederic Sowa.

15) If you change an interface name and meanwhile can sneak in something
    that looks up the name (like SO_BINDTODEVICE or SIOCGIFNAME) we can
    deadlock with CONFIG_PREEMPT=n.  Fix this by providing a helper
    function that properly uses raw_seqcount_begin().  From Nicolas
    Schichan.

16) Chain noise calibration test is inverted in iwlwifi, fix from
    Nikolay Martynov.

17) Properly set TX iwlwifi descriptor flags for back requests.  Fix
    from Emmanuel Grumbach.

18) We can't assume skb_transport_header() is set in xt_TCPOPTSTRAP
    module, fix from Pablo Neira Ayuso.

19) Some crummy APs don't provide the proper High Throughput info in
    association response frames.  Add a workaround by assume we'll use
    whatever is in the beacon/probe.  Fix from Johannes Berg.

20) mac80211 call to rate_idx_match_mask() swaps two arguments (mask and
    channel width).  Fix from Simon Wunderlich.

21) xt_TCPMSS (like xt_TCPOPTSTRAP) must not try to handle fragmented
    frames.  Fix from Phil Oester.

22) Fix rate control regression causing iwlwifi/iwlegacy chips to use
    1Mbit/s on pre-11n networks.  From Moshe Benji and Stanslaw Gruszka.

23) Disable brcmsmac power-save functions, they cause regressions.  From
    Arend van Spriel.

24) Enforce a sane minimum MTU in l2cap_build_cmd() otherwise we can
    easily crash.  Fix from Anderson Lizardo.

25) If a learning packet arrives during vxlan_stop() we crash, easily
    fixed by checking netif_running().  From Stephen Hemminger.

26) Static vxlan FDB entries should not be migrated, also from Stephen.

27) skb_clone() failures not handled in vxlan_xmit(), oops.  Also from
    Stephen.

28) Add minimal driver for AR816x/AR817x ethernet chips, from Johannes
    Berg.

29) Fix regression in userspace VLAN acceleration control, added by the
    802.1ad support changes.  Fix from Fernando Luis Vazquez Cao.

30) Interval selection for MLD queries in the bridging code was
    reversed.  Fix from Linus Lüssing.

31) ipv6's ndisc_send_redirect() erroneously writes to the packet we
    received not the packet we are building to send out.  Fix from
    Matthias Schiffer.

32) Don't free netdev before unregistering it, in usb_8dev can driver.
    From Marc Kleine-Budde.

33) Fix nl80211 attribute buffer races, from Johannes Berg.

34) Although netlink_diag.h is under uapi/ it isn't present in Kbuild.
    From Stephen Hemminger.

35) Wrong address and family passed to MD5 key lookups in TCP, from
    Aydin Arik.

36) phy_type attribute created by SFC driver should not be writable.
    From Ben Hutchings.

37) Receive/Transmit queue allocations in pxa168_eth and mv643xx_eth
    should use kzalloc().  Otherwise if setup fails half-way, we'll

    Rintel.

38) Fix double-allocation of dst (resulting in unfreeable net device) in
    ipv6's init_loopback().  From Gao Feng.

39) Fix fragmentation handling SKB leak in netfilter conntrack, we were
    freeing the wrong skb pointer.  From Phil Oester.

40) Don't report "-1" (SPEED_UNKNOWN) in bond_miimon_commit(), from
    Nikolay Aleksandrov.

When the kernel (compiled with CONFIG_PREEMPT=n) is performing the
rename of a network interface, it can end up waiting for a workqueue
to complete. If userland is able to invoke a SIOCGIFNAME ioctl or a
SO_BINDTODEVICE getsockopt in between, the kernel will deadlock due to
the fact that read_secklock_begin() will spin forever waiting for the
writer process (the one doing the interface rename) to update the
devnet_rename_seq sequence.

This patch fixes the problem by adding a helper (netdev_get_name())
and using it in the code handling the SIOCGIFNAME ioctl and
SO_BINDTODEVICE setsockopt.

The netdev_get_name() helper uses raw_seqcount_begin() to avoid
spinning forever, waiting for devnet_rename_seq->sequence to become
even. cond_resched() is used in the contended case, before retrying
the access to give the writer process a chance to finish.

The use of raw_seqcount_begin() will incur some unneeded work in the
reader process in the contended case, but this is better than
deadlocking the system.

  weeks and everyone involved appears to be reasonably comfortable with
  them now.

  The PM part is one fix for a cpufreq regression introduced recently

   - Fix for an ACPI dock regression introduced by the recent rework of
     the ACPI-based PCI hotplug code (acpiphp) that caused it to be
     initialized before the ACPI dock driver, which is incorrect (ACPI
     dock has to be initialized before acpiphp so that acpiphp can
     register PCI devices on docking stations with it for PCI hotplug on
     re-dock to work).  From Jiang Liu.

   - Fix for PCI resources allocation in the ACPI-based PCI hotplug code
     (acpiphp) that makes it use the same PCI resources assignment rules
     during runtime hotplug that are used during boot (the BIOS' choices
     are now respected in both cases).  This prevents PCI resource
     allocation failures during hotplug from happening in some cases.
     From Jiang Liu.

   - Fix for ordering and synchronization issues during hot-removal of
     PCI devices on docking stations.  It makes the ACPI dock code carry
     out the PCI devices removal synchronously during undock instead of
     spawning a separate asynchronous work item to remove each of them
     without even bothering to wait for all those work items to
     complete.  The hot-addition part is changed analogously.

   - Fix for a regression (introduced a few releases ago) that removed
     the code to register a hotplug notificaion handler for for ATA
     ports/devices inadvertently which prevented ATA bays hotplug from
     working.  The missing code is added back with some improvements.

Commit ede4d7a5 ("gpio/omap: convert gpio irq domain to linear mapping")
converted the OMAP GPIO driver to use a linear mapping for the GPIO IRQ
domain instead of using a legacy mapping. Not using a legacy mapping has
a number of benefits but it requires the platform to support SPARSE_IRQ
which currently is not supported on OMAP1.

So this change caused a regression on OMAP1 platforms [1].

Since this issue is not present on all OMAP2+ platforms, there is no need to
revert the driver to use legacy domain mapping for all the platforms.

When the EEH error is the result of a fenced host bridge, MMIO accesses
can be very slow (milliseconds) to timeout and return all 1's,
thus causing the driver various timeout loops to take way too long and
trigger soft-lockup warnings (in addition to taking minutes to recover).

It might be worthwhile to check if for any of these cases, ffffffff is
a valid possible value, and if not, bail early since that means the HW
is either gone or isolated. In the meantime, checking that the PCI channel
is offline would be workaround of the problem.

fcoe_xmit was coded such that it would skip the vlan net device/layer
and instead set some vlan flags and transmit on the real net device.
The real net device has code that would add the vlan tag for fcoe skbs.
This avoids some extra processing for data frames and provides a small
performance improvement.

Since fcoe_xmit was not using the vlan net device, __vlan_put_tag
within the real net device's xmit routine was ultimately being
called to set the vlan tag.

With the below change the behavior of __vlan_put_tag changed slightly,
it now sets the skb->protocol = vlan_proto. vlan_proto was not a field
being set by fcoe_xmit, so the skb->protocol is now not being set to
ETH_P_8021Q, as it should be.

This patch converts fcoe_xmit to use the vlan_put_tag routine which
will tag the skb and fcoe will continue to transmit fcoe skbs on the
real net device.

For reference, the below change was the one that altered the
__vlan_put_tag behavior.

      Add a protocol argument to the VLAN packet tagging functions. In case of HW
      tagging, we need that protocol available in the ndo_start_xmit functions,
      so it is stored in a new field in the skb. The new field fits into a hole
      (on 64 bit) and doesn't increase the sks's size.

Git commit 90797e6d
("drm/i915: create compact dma scatter lists for gem objects") makes
certain assumptions about the under laying DMA API that are not always
correct.

On a ThinkPad X230 with an Intel HD 4000 with Xen during the bootup
I see:

[drm:intel_pipe_set_base] *ERROR* pin & fence failed
[drm:intel_crtc_set_config] *ERROR* failed to set mode on [CRTC:3], err = -28

Bit of debugging traced it down to dma_map_sg failing (in
i915_gem_gtt_prepare_object) as some of the SG entries were huge (3MB).

That unfortunately are sizes that the SWIOTLB is incapable of handling -
the maximum it can handle is a an entry of 512KB of virtual contiguous
memory for its bounce buffer. (See IO_TLB_SEGSIZE).

Previous to the above mention git commit the SG entries were of 4KB, and
the code introduced by above git commit squashed the CPU contiguous PFNs
in one big virtual address provided to DMA API.

This patch is a simple semi-revert - were we emulate the old behavior
if we detect that SWIOTLB is online. If it is not online then we continue
on with the new compact scatter gather mechanism.

An alternative solution would be for the the '.get_pages' and the
i915_gem_gtt_prepare_object to retry with smaller max gap of the
amount of PFNs that can be combined together - but with this issue
discovered during rc7 that might be too risky.

Merge tag 'drm-intel-fixes-2013-06-24' of git://people.freedesktop.org/~danvet/drm-intel into drm-fixes

One remaining regression fix for i915. I've left it in -fixes for more
than a week since it's in tricky code, and it took us a few kernel
releases to notice the regression at all. The fence leak is especially
annoying on gen2/3 and will kill userspace there quickly. For extra
paranoia we've added a WARN in -next to catch this, things seem to be
solid now.

  drm/i915: Restore fences after resume and GPU resets

Commit 30dcf76a "libata: migrate ACPI code over to new bindings"
mistakenly dropped the code to register hotplug notificaion handler
for ATA port/devices, causing regression for people using ATA bay,
as kernel bug #59871 shows.

Fix this by adding back the hotplug notification handler registration
code.  Since this code has to be run once and notification needs to
be installed on every ATA port/devices handle no matter if there is
actual device attached, we can't do this in binding time for ATA
device ACPI handle, as the binding only occurs when a SCSI device is
created, i.e. there is device attached.  So introduce the
ata_acpi_hotplug_init() function to loop scan all ATA ACPI handles
and if it is available, install the notificaion handler for it during
ATA init time.

With the ATA ACPI handle binding to SCSI device tree, it is possible
now that when the SCSI hotplug work removes the SCSI device, the ACPI
unbind function will find that the corresponding ACPI device has
already been deleted by dock driver, causing a scaring message like:
[  128.263966] scsi 4:0:0:0: Oops, 'acpi_handle' corrupt
Fix this by waiting for SCSI hotplug task finish in our notificaion
handler, so that the removal of ACPI device done in ACPI unbind
function triggered by the removal of SCSI device is run earlier when
ACPI device is still available.

    powerpc/fsl-pci Make PCIe hotplug work with Freescale PCIe controllers

    Up to now the PCIe link status on Freescale PCIe controllers was only
    checked once at boot time. So hotplug did not work. With this patch the
    link status is checked on every config read. PCIe devices not present at
    boot time are found after doing 'echo 1 >/sys/bus/pci/rescan'.

This patch fixes the issue by calling setup_indirect_pci for all device types.
fsl_indirect_read_config is now only used for booke/86xx PCIe controllers.

Pablo Neira Ayuso says:

====================
The following patchset contains five fixes for Netfilter/IPVS, they are:

* A skb leak fix in fragmentation handling in case that helpers are in place,
  it occurs since the IPV6 NAT infrastructure, from Phil Oester.

* Fix SCTP port mangling in ICMP packets for IPVS, from Julian Anastasov.

* Fix event delivery in ctnetlink regarding the new connlabel infrastructure,
  from Florian Westphal.

* Fix mangling in the SIP NAT helper, from Balazs Peter Odor.

* Fix crash in ipt_ULOG introduced while adding netnamespace support,
  from Gao Feng.

I'll take care of passing several of these patches to -stable once they hit
Linus' tree.

Make sure that a chip reset is done when IDLE is turned
off - this fixes authentication timeouts.
