Donald reported that IPv6 route leaking between VRFs is not working.
The root cause is the strict argument in the call to rt6_lookup when
validating the nexthop spec.

ip6_route_check_nh validates the gateway and device (if given) of a
route spec. It in turn could call rt6_lookup (e.g., lookup in a given
table did not succeed so it falls back to a full lookup) and if so
sets the strict argument to 1. That means if the egress device is given,
the route lookup needs to return a result with the same device. This
strict requirement does not work with VRFs (IPv4 or IPv6) because the
oif in the flow struct is overridden with the index of the VRF device
to trigger a match on the l3mdev rule and force the lookup to its table.

The right long term solution is to add an l3mdev index to the flow
struct such that the oif is not overridden. That solution will not
backport well, so this patch aims for a simpler solution to relax the
strict argument if the route spec device is an l3mdev slave. As done
in other places, use the FLOWI_FLAG_SKIP_NH_OIF to know that the
RT6_LOOKUP_F_IFACE flag needs to be removed.

Fix vlan tag handling for vlan packets without ethernet headers

Eric Dumazet reported syzbot found a new bug which leads to underflow of
size argument of memmove(), causing crash[1]. This can be triggered by tun
devices.

The underflow happened because skb_vlan_untag() did not expect vlan packets
without ethernet headers, and tun can produce such packets.
I also checked vlan_insert_inner_tag() and found a similar bug.

This series fixes these problems.

In some situation vlan packets do not have ethernet headers. One example
is packets from tun devices. Users can specify vlan protocol in tun_pi
field instead of IP protocol. When we have a vlan device with reorder_hdr
disabled on top of the tun device, such packets from tun devices are
untagged in skb_vlan_untag() and vlan headers will be inserted back in
vlan_insert_inner_tag().

vlan_insert_inner_tag() however did not expect packets without ethernet
headers, so in such a case size argument for memmove() underflowed.

We don't need to copy headers for packets which do not have preceding
headers of vlan headers, so skip memmove() in that case.
Also don't write vlan protocol in skb->data when it does not have enough
room for it.

dm_get_bdev_for_ioctl()'s return of 0 or 1 must be the result from
prepare_ioctl (1 means the ioctl was issued to a partition, 0 means it

than bdgrab when issuing pass-through ioctl") reused the variable 'r'
to store the return from blkdev_get() that follows prepare_ioctl()
-- whereby dropping prepare_ioctl()'s result on the floor.

This can lead to an ioctl or persistent reservation being issued to a
partition going unnoticed, which implies the extra permission check for
CAP_SYS_RAWIO is skipped.

Fix this by using a different variable to store blkdev_get()'s return.

Today, driver drops received packets which are indicated as
invalid checksum by the device. Instead of dropping such packets,
pass them to the stack with CHECKSUM_NONE indication in skb.

It turns out that the loop where we read manufacturer
jedec_read_mfd() can under some circumstances get a
CFI_MFR_CONTINUATION repeatedly, making the loop go
over all banks and eventually hit the end of the
map and crash because of an access violation:

Fix this by breaking the loop with a return 0 if
the offset exceeds the map size.

My recent change to netvsc drive in how receive flags are handled
broke multicast.  The Hyper-v/Azure virtual interface there is not a
multicast filter list, filtering is only all or none. The driver must

Description:
Crash was reported with syzkaller pointing to lan78xx_write_reg routine.

Root-cause:
Proper cleanup of workqueues and init/setup routines was not happening
in failure conditions.

Fix:
Handled the error conditions by cleaning up the queues and init/setup
routines.

 "Some more powerpc fixes for 4.16. Apologies if this is a bit big at
  rc7, but they're all reasonably important fixes. None are actually for

  our point of view.

   - Fix missing AT_BASE_PLATFORM (in auxv) when we're using a new
     firmware interface for describing CPU features.

   - Fix lost pending interrupts due to a race in our interrupt
     soft-masking code.

   - A workaround for a nest MMU bug with TLB invalidations on Power9.

   - A workaround for broadcast TLB invalidations on Power9.

   - Fix a bug in our instruction SLB miss handler, when handling bad
     addresses (eg. >= TASK_SIZE), which could corrupt non-volatile user
     GPRs.

As of the start of 2018, I am no longer paid to support the core 32-bit
ARM architecture code.  This means that this code is no longer
commercially supported, and is now only supported through voluntary
effort.

I will continue to merge patches as and when able, but this will be at a
lower priority than before (which means a longer latency.) I have also
be scaled back the amount of time spent reading email, so email that is
intended for my attention needs to make itself plainly obvious, or I
will miss it.

In an attempt to reduce the amount of email Cc'd to me, exclude
arch/arm/boot/dts from the maintainers patterns, but add entries for the
SolidRun platforms I look after.

A crash is observed when kmemleak_scan accesses the object->pointer,
likely due to the following race.

  TASK A             TASK B                     TASK C
  kmemleak_write
   (with "scan" and
   NOT "scan=on")
  kmemleak_scan()
                     create_object
                     kmem_cache_alloc fails
                     kmemleak_disable

  update_checksum
  crash - object->pointer
   freed (DEBUG_PAGEALLOC)

kmemleak_do_cleanup waits for the scan thread to complete, but not for
direct call to kmemleak_scan via kmemleak_write.  So add a wait for
kmemleak_scan completion before...
