Currently, iflink of the parent interface was always accessed, even
when interface didn't have a parent and hence we crashed there.
Handle the interface types properly: for a child interface, return
the ifindex of the parent, for parent interface, return its ifindex.
For child devices, make sure to set the parent pointer prior to
invoking register_netdevice(), this allows the new ndo to be called
by the stack immediately after the child device is registered.

When you redirect a VLAN device to any device, you end up with
crap in af_packet on the xmit path because hard_header_len is
not equal to skb->mac_len. So the redirected packet contains
four extra bytes at the start which then gets interpreted as
part of the MAC address.
This patch fixes this by only pushing skb->mac_len. We also

2) Some TCP Congestion Control modules provide information

1.
first bug is a silly mistake. It broke tracing examples and prevented
simple bpf programs from loading.
In the following code:
if (insn->imm == 0 && BPF_SIZE(insn->code) == BPF_W) {
} else if (...) {
// this part should have been executed when
// insn->code == BPF_W and insn->imm != 0
}
Obviously it's not doing that. So simple instructions like:
r2 = *(u64 *)(r1 + 8)
will be rejected. Note the comments in the code around these branches
were and still valid and indicate the true intent.
Replace it with:
if (BPF_SIZE(insn->code) != BPF_W)
continue;
if (insn->imm == 0) {
} else if (...) {
// now this code will be executed when
// insn->code == BPF_W and insn->imm != 0
}
2.
second bug is more subtle.
If malicious code is using the same dest register as source register,
the checks designed to prevent the same instruction to be used with different
pointer types will fail to trigger, since we were assigning src_reg_type
when it was already overwritten by check_mem_access().
The fix is trivial. Just move line:
src_reg_type = regs[insn->src_reg].type;
before check_mem_access().
Add new 'access skb fields bad4' test to check this case.

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.

stmmac: Correct flow control configuration
This 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.

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.

Intel Wired LAN Driver Updates 2015-04-14
This 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 9a2620c877 ("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.

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.

Pull networking updates from David Miller:
1) Add BQL support to via-rhine, from Tino Reichardt.
2) Integrate SWITCHDEV layer support into the DSA layer, so DSA drivers
can support hw switch offloading. From Floria Fainelli.
3) Allow 'ip address' commands to initiate multicast group join/leave,
from Madhu Challa.
4) Many ipv4 FIB lookup optimizations from Alexander Duyck.
5) Support EBPF in cls_bpf classifier and act_bpf action, from Daniel
Borkmann.
6) Remove the ugly compat support in ARP for ugly layers like ax25,
rose, etc. And use this to clean up the neigh layer, then use it to
implement MPLS support. All from Eric Biederman.
7) Support L3 forwarding offloading in switches, from Scott Feldman.
8) Collapse the LOCAL and MAIN ipv4 FIB tables when possible, to speed
up route lookups even further. From Alexander Duyck.
9) Many improvements and bug fixes to the rhashtable implementation,
from Herbert Xu and Thomas Graf. In particular, in the case where
an rhashtable user bulk adds a large number of items into an empty
table, we expand the table much more sanely.
10) Don't make the tcp_metrics hash table per-namespace, from Eric
Biederman.
11) Extend EBPF to access SKB fields, from Alexei Starovoitov.
12) Split out new connection request sockets so that they can be
established in the main hash table. Much less false sharing since
hash lookups go direct to the request sockets instead of having to
go first to the listener then to the request socks hashed
underneath. From Eric Dumazet.
13) Add async I/O support for crytpo AF_ALG sockets, from Tadeusz Struk.
14) Support stable privacy address generation for RFC7217 in IPV6. From
Hannes Frederic Sowa.
15) Hash network namespace into IP frag IDs, also from Hannes Frederic

Pull ARM updates from Russell King:
"Included in this update are both some long term fixes and some new
features.
Fixes:
- An integer overflow in the calculation of ELF_ET_DYN_BASE.
- Avoiding OOMs for high-order IOMMU allocations
- 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
on their cameras.
- Versatile Express needs an errata workaround enabled for CPU
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
ARM architected timer.
- Perf support for Scorpion performance monitoring units"
vdso semantic conflict fixed up as per linux-next.

Pull power management and ACPI updates from Rafael Wysocki:
"These are mostly fixes and cleanups all over, although there are a few
items that sort of fall into the new feature category.
First off, we have new callbacks for PM domains that should help us to
handle some issues related to device initialization in a better way.
There also is some consolidation in the unified device properties API
area allowing us to use that inferface for accessing data coming from
platform initialization code in addition to firmware-provided data.
We have some new device/CPU IDs in a few drivers, support for new
chips and a new cpufreq driver too.

This is a feature to enable better debugging of user reported issues by
allowing a bash script to acquire information about the internal hardware

then be sent to Intel. This is a critical debugging feature for helping us

Intel Wired LAN Driver Updates 2015-04-14
This 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.
