sunvnet: Use RCU to synchronize port usage with vnet_port_remove()
A vnet_port_remove could be triggered as a result of an ldm-unbind
operation by the peer, module unload, or other changes to the
inter-vnet-link configuration. When this is concurrent with
vnet_start_xmit(), there are several race sequences possible,
such as
thread 1 thread 2
vnet_start_xmit
-> tx_port_find
spin_lock_irqsave(&vp->lock..)
ret = __tx_port_find(..)

This patch adds RCU locking for port access so that vnet_port_remove
will correctly clean up port-related state.

Intel Wired LAN Driver Updates 2014-10-23
This series contains updates to i40e and i40evf.
Jesse modifies the i40e driver to only notify the firmware on link up/down

state by using the admin queue receive event for link events as a signal
to tell the driver to update link state.
Jeff (me) cleans up the inconsistent use of tabs for indentation in the admin
queue command header file.
Neerav converts the use of udelay() to usleep_range().
Anjali fixes a bug where receive would stop after some stress by adding
a sleep and restart as well as moving the setting of flow control because
it should be done at a PF level and not a VSI level.

Marvell PXA168 libphy handling and Berlin Ethernet
This patch series deals with a removing a IP feature that can be found
on all currently supported Marvell Ethernet IP (pxa168_eth, mv643xx_eth,
mvneta). The MAC IP allows to automatically perform PHY auto-negotiation
without software interaction.
However, this feature (a) fundamentally clashes with the way libphy works
and (b) is unable to deal with quirky PHYs that require special treatment.
In this series, pxa168_eth driver is rewritten to completely disable that
feature and properly deal with libphy provided PHYs.
As usual, a branch on top of v3.18-rc1 can be found at
Patches 1-5 should go through David's net tree, I'll pick up the DT patches
6-9.
There have been some changes,
compared to the RFT
- added phy-connection-type property to BG2Q PHY DT node
- bail out from pxa168_eth_adjust_link when there is no change in
PHY parameters. Also, add a call to phy_print_status.
compared to v1
- move phy-connection-type to ethernet node instead of PHY node
Patch 1 adds support for Marvell 88E3016 FastEthernet PHY that is also
integrated in Marvell Berlin BG2/BG2CD SoCs.
Patch 2 allows to pass phy_interface_t on pxa168_eth platform_data that
is only used by mach-mmp/gplug. From the board setup, I guessed gplug's
PHY is connected via RMII. The patch still isn't even compile tested.
Patches 3-5 prepare proper libphy handling and finally remove all in-driver
PHY mangling related to the feature explained above.
Patches 6-9 add corresponding ethernet DT nodes to BG2, BG2CD, add a
phy-connection-type property to BG2Q and enable ethernet on BG2-based Sony
NSZ-GS7. I have tested all this on GS7 successfully with ip=dhcp on 100M FD.

net: make skb_gso_segment error handling more robust
skb_gso_segment has three possible return values:
1. a pointer to the first segmented skb
2. an errno value (IS_ERR())
3. NULL. This can happen when GSO is used for header verification.
However, several callers currently test IS_ERR instead of IS_ERR_OR_NULL
and would oops when NULL is returned.
Note that these call sites should never actually see such a NULL return
value; all callers mask out the GSO bits in the feature argument.
However, there have been issues with some protocol handlers erronously not
respecting the specified feature mask in some cases.
It is preferable to get 'have to turn off hw offloading, else slow' reports
rather than 'kernel crashes'.

net: gso: use feature flag argument in all protocol gso handlers
skb_gso_segment() has a 'features' argument representing offload features
available to the output path.
A few handlers, e.g. GRE, instead re-fetch the features of skb->dev and use
those instead of the provided ones when handing encapsulation/tunnels.
Depending on dev->hw_enc_features of the output device skb_gso_segment() can
then return NULL even when the caller has disabled all GSO feature bits,
as segmentation of inner header thinks device will take care of segmentation.
This e.g. affects the tbf scheduler, which will silently drop GRE-encap GSO skbs
that did not fit the remaining token quota as the segmentation does not work
when device supports corresponding hw offload capabilities.

The following patchset contains netfilter fixes for your net tree,
they are:
1) Fix missing MODULE_LICENSE() in the new nf_reject_ipv{4,6} modules.
2) Restrict nat and masq expressions to the nat chain type. Otherwise,
users may crash their kernel if they attach a nat/masq rule to a non
nat chain.
3) Fix hook validation in nft_compat when non-base chains are used.
Basically, initialize hook_mask to zero.
4) Make sure you use match/targets in nft_compat from the right chain
type. The existing validation relies on the table name which can be
avoided by
5) Better netlink attribute validation in nft_nat. This expression has
to reject the configuration when no address and proto configurations
are specified.
6) Interpret NFTA_NAT_REG_*_MAX if only if NFTA_NAT_REG_*_MIN is set.
Yet another sanity check to reject incorrect configurations from
userspace.
7) Conditional NAT attribute dumping depending on the existing
configuration.

ax88179_178a: fix bonding failure
The following patch fixes a bug which causes the ax88179_178a driver to be
incapable of being added to a bond.
When I brought up the issue with the bonding maintainers, they indicated
that the real problem was with the NIC driver which must return zero for
success (of setting the MAC address). I see that several other NIC drivers
follow that pattern by either simply always returing zero, or by passing
through a negative (error) result while rewriting any positive return code
to zero. With that same philisophy applied to the ax88179_178a driver, it
allows it to work correctly with the bonding driver.
I believe this is suitable for queuing in -stable, as it's a small, simple,
and obvious fix that corrects a defect with no other known workaround.
This patch is against vanilla 3.17(.0).

sparc64: Do not define thread fpregs save area as zero-length array.
This breaks the stack end corruption detection facility.
What that facility does it write a magic value to "end_of_stack()"
and checking to see if it gets overwritten.
"end_of_stack()" is "task_thread_info(p) + 1", which for sparc64 is
the beginning of the FPU register save area.
So once the user uses the FPU, the magic value is overwritten and the
debug checks trigger.
Fix this by making the size explicit.
Due to the size we use for the fpsaved[], gsr[], and xfsr[] arrays we
are limited to 7 levels of FPU state saves. So each FPU register set
is 256 bytes, allocate 256 * 7 for the fpregs area.

sparc64: Fix corrupted thread fault code.
Every path that ends up at do_sparc64_fault() must install a valid
FAULT_CODE_* bitmask in the per-thread fault code byte.
Two paths leading to the label winfix_trampoline (which expects the
FAULT_CODE_* mask in register %g4) were not doing so:
1) For pre-hypervisor TLB protection violation traps, if we took
the 'winfix_trampoline' path we wouldn't have %g4 initialized
with the FAULT_CODE_* value yet. Resulting in using the
TLB_TAG_ACCESS register address value instead.
2) In the TSB miss path, when we notice that we are going to use a
hugepage mapping, but we haven't allocated the hugepage TSB yet, we
still have to take the window fixup case into consideration and
in that particular path we leave %g4 not setup properly.
Errors on this sort were largely invisible previously, but after
commit 4ccb9272892c33ef1c19a783cfa87103b30c2784 ("sparc64: sun4v TLB
error power off events") we now have a fault_code mask bit
(FAULT_CODE_BAD_RA) that triggers due to this bug.
FAULT_CODE_BAD_RA triggers because this bit is set in TLB_TAG_ACCESS
(see #1 above) and thus we get seemingly random bus errors triggered
for user processes.

x86,kvm,vmx: Preserve CR4 across VM entry
CR4 isn't constant; at least the TSD and PCE bits can vary.
TBH, treating CR0 and CR3 as constant scares me a bit, too, but it looks
like it's correct.
This adds a branch and a read from cr4 to each vm entry. Because it is
extremely likely that consecutive entries into the same vcpu will have
the same host cr4 value, this fixes up the vmcs instead of restoring cr4
after the fact. A subsequent patch will add a kernel-wide cr4 shadow,
reducing the overhead in the common case to just two memory reads and a
branch.

futex: Ensure get_futex_key_refs() always implies a barrier
Commit b0c29f79ecea (futexes: Avoid taking the hb->lock if there's
nothing to wake up) changes the futex code to avoid taking a lock when
there are no waiters. This code has been subsequently fixed in commit 11d4616bd07f (futex: revert back to the explicit waiter counting code).
Both the original commit and the fix-up rely on get_futex_key_refs() to
always imply a barrier.
However, for private futexes, none of the cases in the switch statement
of get_futex_key_refs() would be hit and the function completes without
a memory barrier as required before checking the "waiters" in
futex_wake() -> hb_waiters_pending(). The consequence is a race with a
thread waiting on a futex on another CPU, allowing the waker thread to
read "waiters == 0" while the waiter thread to have read "futex_val ==
locked" (in kernel).
Without this fix, the problem (user space deadlocks) can be seen with
Android bionic's mutex implementation on an arm64 multi-cluster system.
