For the short-term solution, lets fix bpf helper functions to use
skb->mac_header relative offsets instead of skb->data in order to
get the same eBPF programs with cls_bpf and act_bpf work on ingress
and egress qdisc path. We need to ensure that mac_header is set
before calling into programs. This is effectively the first option
from below referenced discussion.More long term solution for LD_ABS|LD_IND instructions will be more
intrusive but also more beneficial than this, and implemented later
as it's too risky at this point in time.I.e., we plan to look into the option of moving skb_pull() out of
eth_type_trans() and into netif_receive_skb() as has been suggested
as second option. Meanwhile, this solution ensures ingress can be
used with eBPF, too, and that we won't run into ABI troubles later.
For dealing with negative offsets inside eBPF helper functions,
we've implemented bpf_skb_clone_unwritable() to test for unwriteable
headers.Reference: http://thread.gmane.org/gmane.linux.network/359129/focus=359694

====================
stmmac: Correct flow control configurationThis series of patches corrects flow control configuration for the Synopsys
GMAC driver.Flow control is configured based on a configurable receive fifo size. If
less than 4Kbytes flow control is left disabled and a warning is presented. If
a receive fifo size is not specified, flow control is left disabled to
maintain current behavior. Unicast pause detection was disabled, but is now
enabled. The pause time was modified to be maximum time per a XON/XOFF
flow control mode of operation.This patch was tested on an Altera Cyclone 5 and an Altera Arria 10 devkit,
and verified that flow control operates as expected when enabled.Please consider this series for inclusion so that flow control will
function as expected for the Synopsys GMAC controller.

An oops exists in the flow of stmmac_release().
phy_ethtool_get_wol() depends on phydev->drv.
phydev->drv will be null after stmmac_mdio_unreg() completes.Steps to reproduce on Quark X1000:
1. ifconfig eth0 192.168.0.1
2. rmmod stmmac_pciTo fix this stmmac_mdio_unreg() should be run after unregister_netdev().

set_filter_wr is requesting __GFP_NOFAIL allocation although it can return
ENOMEM without any problems obviously (t4_l2t_set_switching does that
already). So the non-failing requirement is too strong without any
obvious reason. Drop __GFP_NOFAIL and reorganize the code to have the
failure paths easier.The same applies to _c4iw_write_mem_dma_aligned which uses __GFP_NOFAIL
and then checks the return value and returns -ENOMEM on failure. This
doesn't make any sense what so ever. Either the allocation cannot fail or
it can.del_filter_wr seems to be safe as well because the filter entry is not
marked as pending and the return value is propagated up the stack up to
c4iw_destroy_listen.Signed-off-by: Michal Hocko

====================
Intel Wired LAN Driver Updates 2015-04-14This series contains updates to i40e and i40evf.
Mitch provides a fix for i40e, where VFs were gone and the associated
VSI's had been removed and the rings were not stopped, which in some
circumstances cased memory corruption or DMAR errors. So stop all the
rings associated with each VF before releasing its resources. Also
cleaned up a poorly indented piece of code. Fixes VF link state, where
VF devices were assuming link is up unless told otherwise, which means
that VFs instantiated on a PF with no link, would report the wrong state.Anjali adds support to add Flow director Sideband rules for a VF from it's
PF. Fixes a recently discovered hardware issue, where after a VFLR
hardware might be indicating to us a reset completion little too early, so
wait another 10 msec for cache to be cleaned up.Jesse enables the user to dump the internal hardware state for better
debugging by allowing a bash script to acquire information about the
internal hardware state. The data output to the kernel log is collected
by the script and can then be sent to Intel. Also fixed a possible
failure path to allocate memory that was found by smatch. Cleaned up
unused local variables.

Commit 9a2620c877454 ("bnx2x: prevent WARN during driver unload")
switched the napi/busy_lock locking mechanism from spin_lock() into
spin_lock_bh(), breaking inter-operability with netconsole, as netpoll
disables interrupts prior to calling our napi mechanism.This switches the driver into using atomic assignments instead of the
spinlock mechanisms previously employed.Based on initial patch from Yuval Mintz & Ariel Elior
I basically added softirq starvation avoidance, and mixture
of atomic operations, plain writes and barriers.Note this slightly reduces the overhead for this driver when no
busy_poll sockets are in use.Fixes: 9a2620c877454 ("bnx2x: prevent WARN during driver unload")

The code sets the expiry value of the timer to a relative value and
starts it with hrtimer_start_expires. That's fine, but that only works
once. The timer is started in relative mode, so the expiry value gets
overwritten with the absolut expiry time (now + expiry).So once the timer expired, a new call to hrtimer_start_expires results
in an immidiately expired timer, because the expiry value is
already in the past.Use the proper mechanisms to (re)start the timer in the intended way.

- SMP requires the data cache to be enabled for synchronisation
primitives to work, so prevent the CPU_DCACHE_DISABLE option being
visible on SMP builds.- A bug going back 10+ years in the noMMU ARM94* CPU support code,
where it corrupts registers. Found by folk getting Linux running

hot-unplug to work.Features:
- Clean up module linker by handling out of range relocations
separately from relocation cases we don't handle.- Fix a long term bug in the pci_mmap_page_range() code, which we
hope won't impact userspace (we hope there's no users of the
existing broken interface.)- Don't map DMA coherent allocations when we don't have a MMU.
- Drop experimental status for SMP_ON_UP.
- Warn when DT doesn't specify ePAPR mandatory cache properties.
- Add documentation concerning how we find the start of physical
memory for AUTO_ZRELADDR kernels, detailing why we have chosen the
mask and the implications of changing it.- Updates from Ard Biesheuvel to address some issues with large
kernels (such as allyesconfig) failing to link.- Allow hibernation to work on modern (ARMv7) CPUs - this appears to
have never worked in the past on these CPUs.- Enable IRQ_SHOW_LEVEL, which changes the /proc/interrupts output
format (hopefully without userspace breaking... let's hope that if
it causes someone a problem, they tell us.)- Fix tegra-ahb DT offsets.
- Rework ARM errata 643719 code (and ARMv7 flush_cache_louis()/
flush_dcache_all()) code to be more efficient, and enable this
errata workaround by default for ARMv7+SMP CPUs. This complements
the Versatile Express fix above.- Rework ARMv7 context code for errata 430973, so that only Cortex A8
CPUs are impacted by the branch target buffer flush when this
errata is enabled. Also update the help text to indicate that all
r1p* A8 CPUs are impacted.- Switch ARM to the generic show_mem() implementation, it conveys all
the information which we were already reporting.- Prevent slow timer sources being used for udelay() - timers running
at less than 1MHz are not useful for this, and can cause udelay()
to return immediately, without any wait. Using such a slow timer
is silly.- VDSO support for 32-bit ARM, mainly for gettimeofday() using the

This is a feature to enable better debugging of user reported issues by
allowing a bash script to acquire information about the internal hardware
state. The data output to the kernel log is collected by the script and can
then be sent to Intel. This is a critical debugging feature for helping us
interpret and reproduce complex customer setups.Change-ID: Ie8b3ab09086d6870a709015f51ada05af10b41bb

====================
Intel Wired LAN Driver Updates 2015-04-14This series contains updates to fm10k only.
Fixed transmit statistics which was actually using values from the
receive ring, instead of the transmit ring. Fixed up spelling mistakes
in code comments and resolved unused argument warnings. Added support
for netconsole. Fixed up statistic reporting so that we are only
reporting from actual queues as well as display PF only stats for
just the PF and not the VF. Also fixed an issue that when returning
virtualization queues from the VF back to the PF, we were retaining
the VF rate limiter.Fixed up the driver to use a separate workqueue, which helps reduce
and stabilize latency between scheduling the work in our interrupt and
actually performing the work.Fixed a bug where the VF tried to set a multicast address before
requesting the required xcast mode.Fix VF multicast update since VFs were being improperly added to the
switch's mutlicast group. The error stems from the fact that incorrect
arguments were passed to the update_mc_addr().Thanks to Alex Duyck for the extensive review.

Pull i2c updates from Wolfram Sang:
"Most notable:- introducing the i2c_quirk infrastructure. Now, flaws of I2C
controllers can be described and the core will check if the flaws
collide with the messages to be sent- wait_for_completion return type cleanup series
- new drivers for Digicolor, Netlogic XLP, Ingenic JZ4780
- updates to the I2C slave framework which include API changes. Its
only user was updated, too. Documentation was finally added- changed dynamic bus numbering for the DT case. This could change
bus numbers for users. However, it fixes a collision where dynamic
and static busses request the same id.- driver bugfixes, cleanups"
