outer_header_zero() routine checks if the outer_headers match of a
flow-table entry are all zero.
This function uses the size of whole fte_match_param, instead of just
the outer_headers member, causing failure to detect all-zeros if
any other members of the fte_match_param are non-zero.

On interface remove, the clean-up was done incorrectly causing
an error in the log:
"SET_FLOW_TABLE_ROOT(0x92f) op_mod(0x0) failed...syndrome (0x7e9f14)"
This was caused by the following flow:
-ndo_uninit:
Move QP state to RST (this disconnects the QP from FT),
the QP cannot be attached to any FT unless it is in RTS.
-mlx5_rdma_netdev_free:
cleanup_rx: Destroy FT
cleanup_tx: Destroy QP and remove QPN from FT
This caused a problem when destroying current FT we tried to
re-attach the QP to the next FT which is not needed.
The correct flow is:
-mlx5_rdma_netdev_free:
cleanup_rx: remove QPN from FT & Destroy FT
cleanup_tx: Destroy QP

The tx_enabled lag event field is used to determine whether a slave is
active.
Current logic uses this value only if the mode is active-backup.
However, LACP mode, although considered a load balancing mode, can mark
a slave as inactive in certain situations (e.g., LACP timeout).
This fix takes the tx_enabled value into account when remapping, with
no respect to the LAG mode (this should not affect the behavior in XOR
mode, since in this mode both slaves are marked as active).

That commit was part of the changes moving x86 to the generic CPU hotplug
interrupt migration code. The force flag was required on x86 before the
hierarchical irqdomain rework, but invoking set_affinity() with force=true
stayed and had no side effects.
At some point in the past, the force flag got repurposed to support the
exynos timer interrupt affinity setting to a not yet online CPU, so the
interrupt controller callback does not verify the supplied affinity mask
against cpu_online_mask.
Setting the flag in the CPU hotplug code causes the cpu online masking to
be blocked on these irq controllers and results in potentially affining an
interrupt to the CPU which is unplugged, i.e. instead of moving it away,
it's just reassigned to it.
As the force flags is not longer needed on x86, it's safe to revert that
patch so the ARM irqchips which use the force flag work again.
Add comments to that effect, so this won't happen again.
Note: The online mask handling should be done in the generic code and the
force flag and the masking in the irq chips removed all together, but
that's not a change possible for 4.13.

Since the PMU register interface is banked per CPU, CPU PMU interrrupts
cannot be handled by a CPU other than the one with the PMU asserting the
interrupt. This means that migrating PMU SPIs, as we do during a CPU
hotplug operation doesn't make any sense and can lead to the IRQ being
disabled entirely if we route a spurious IRQ to the new affinity target.
This has been observed in practice on AMD Seattle, where CPUs on the
non-boot cluster appear to take a spurious PMU IRQ when coming online,
which is routed to CPU0 where it cannot be handled.
This patch passes IRQF_PERCPU for PMU SPIs and forcefully sets their
affinity prior to requesting them, ensuring that they cannot
be migrated during hotplug events. This interacts badly with the DB8500
erratum workaround that ping-pongs the interrupt affinity from the handler,
so we avoid passing IRQF_PERCPU in that case by allowing the IRQ flags
to be overridden in the platdata.

The commit to rework the headroom check in start_xmit() now calls
pxskb_expand_head() unconditionally if the header is CoW. Unfortunately,
it does so with the delta between the extant headroom and the header
length, which may be negative if there is already sufficient headroom.
pskb_expand_head() does allow for size being 0, in which case it just
copies, so clamp the header delta to zero.
Opening Chrome (and all my tabs) on a PCIE device was enough to reliably
hit this.

Turns out that just writing CURPOS isn't sufficient to move the cursor
on some platforms. My 830 works just fine, but eg. 945 and PNV don't.
On those platforms we need to arm even the CURPOS update with a
CURBASE write.
Even worse, a write to any of the cursor register apart from CURBASE
will cancel an already pending cursor update. So if we have armed a
CURCNTR/CURBASE update, a subsequent CURPOS write prior to vblank
would cancel that armed update. Thus we're left with a cursor that
doesn't appear to move, or even change shape.
Fix the problem by always performing the CURBASE write after a
CURPOS write. Bspec is somewhat unclear which platforms actually
require this CURBASE write and which don't. So to keep it simple
and to make sure we really fix the problem across all supported
devices, let's just perform the CURBASE write unconditionally.

Commit b1f5bfc27a19 ("sctp: don't dereference ptr before leaving
_sctp_walk_{params, errors}()") tried to fix the issue that it
may overstep the chunk end for _sctp_walk_{params, errors} with
'chunk_end > offset(length) + sizeof(length)'.
But it introduced a side effect: When processing INIT, it verifies
the chunks with 'param.v == chunk_end' after iterating all params
by sctp_walk_params(). With the check 'chunk_end > offset(length)
+ sizeof(length)', it would return when the last param is not yet
accessed. Because the last param usually is fwdtsn supported param
whose size is 4 and 'chunk_end == offset(length) + sizeof(length)'
This is a badly issue even causing sctp couldn't process 4-shakes.
Client would always get abort when connecting to server, due to
the failure of INIT chunk verification on server.
The patch is to use 'chunk_end <= offset(length) + sizeof(length)'
instead of 'chunk_end < offset(length) + sizeof(length)' for both
_sctp_walk_params and _sctp_walk_errors.

In dccp_v6_conn_request, after reqsk gets alloced and hashed into
ehash table, reqsk's refcnt is set 3. one is for req->rsk_timer,
one is for hlist, and the other one is for current using.
The problem is when dccp_v6_conn_request returns and finishes using
reqsk, it doesn't put reqsk. This will cause reqsk refcnt leaks and
reqsk obj never gets freed.
Jianlin found this issue when running dccp_memleak.c in a loop, the
system memory would run out.
dccp_memleak.c:
int s1 = socket(PF_INET6, 6, IPPROTO_IP);
bind(s1, &sa1, 0x20);
listen(s1, 0x9);
int s2 = socket(PF_INET6, 6, IPPROTO_IP);
connect(s2, &sa1, 0x20);
close(s1);
close(s2);
This patch is to put the reqsk before dccp_v6_conn_request returns,
just as what tcp_conn_request does.

The buffer passed to bpf_obj_get_info_by_fd() should be initialized
to zeros. Kernel will enforce that to guarantee we can safely extend
info structures in the future.
Making the bpf_obj_get_info_by_fd() call in libbpf perform the zeroing
is problematic, however, since some members of the info structures
may need to be initialized by the callers (for instance pointers
to buffers to which kernel is to dump translated and jited images).
Remove the zeroing and fix up the in-tree callers before any kernel
has been released with this code.
As Daniel points out this seems to be the intended operation anyway,
since commit 95b9afd3987f ("bpf: Test for bpf ID") is itself setting
the buffer pointers before calling bpf_obj_get_info_by_fd().

proofing, by changing how the driver displays the UDP tunnel type.
Paul adds a retry in releasing resources if the admin queue times out
during the first attempt to release the resources.
Jesse fixes up references to 32bit timspec, since there are a small set
of errors on 32 bit, so we need to be using the right calls for dealing
with timespec64 variables. Cleaned up code indentation and corrected
an "if" conditional check, as well as making the code flow more clear.
Cast or changed the types to remove warnings for comparing signed and
unsigned types. Adds missing includes in i40evf, which were being used
but were not being directly included.
Daniel Borkmann fixes i40e to fill the XDP prog_id with the id just like
other XDP enabled drivers, so that on dump we can retrieve the attached
program based on the id and dump BPF insns, opcodes, etc back to user
space.
Tushar Dave adds le32_to_cpu while evaluating the hardware descriptor
fields, since they are in little-endian format. Also removed
unnecessary "__packed" to a couple of i40evf structures.
Stefan Assmann fixes an issue when an administratively set MAC was set
and should now be switched back to 00:00:00:00:00:00, the pf_set_mac
flag is not being toggled back to false.

====================
10GbE Intel Wired LAN Driver Updates 2017-07-25
This series contains updates to ixgbe only.
Tony provides all of the changes in the series, starting with adding a
check to ensure that adding a MAC filter was successful, before setting the
MACVLAN. In order to receive notifications of link configurations of the
external PHY and support the configuration of the internal iXFI link on
X552 devices, Tony enables LASI interrupts. Update the iXFI driver code
flow, since the MAC register NW_MNG_IF_SEL fields have been redefined for
X553 devices, so add MAC checks for iXFI flows. Added additional checks
for flow control autonegotiation, since it is not support for X553 fiber
and XFI devices.
v2: removed unnecessary parens noticed by David Miller in patch 6 of the
series.
v3: dropped patch 6 of the original series, while we work out a more
generic solution for malicious driver detection (MDD) support.
v4: updated patch 1 of the series with the comments from Joe Perches which
were:
- switched logic to return on error
- return 0 on success
- declare retval as an integer

Commit bd8b2441742b ("NFS: Store the raw NFS access mask in the inode's
access cache") changed how the access results are stored after an
access() call. An NFS v4 OPEN might have access bits returned with the
opendata, so we should use the NFS4_ACCESS values when determining the
return value in nfs4_opendata_access().

Add a new target to install the bpf.h header to $(prefix)/include/bpf/
directory. This is necessary to build standalone applications using
libbpf, without the need to clone the kernel sources and point to them.

Commit de77ecd4ef02 ("bonding: improve link-status update in mii-monitoring")
moves link status commitment into bond_mii_monitor(), but it still relies
on the return value of bond_miimon_inspect() as the hint. We need to return
non-zero as long as we propose a link status change.

Currently dm_dax_flush() is not being called, even if underlying dax
device supports write cache, because DAXDEV_WRITE_CACHE is not being
propagated up to the DM dax device.
If the underlying dax device supports write cache, set
DAXDEV_WRITE_CACHE on the DM dax device. This will cause dm_dax_flush()
to be called.
Fixes: abebfbe2f7 ("dm: add ->flush() dax operation support")
