There are several devices that can receive vlan tagged packets with
CHECKSUM_PARTIAL like tap, possibly veth and xennet.
When (multiple) vlan tagged packets with CHECKSUM_PARTIAL are forwarded
by bridge to a device with the IP_CSUM feature, they end up with checksum
error because before entering bridge, the network header is set to
ETH_HLEN (not including vlan header length) in __netif_receive_skb_core(),
get_rps_cpu(), or drivers' rx functions, and nobody fixes the pointer later.
Since the network header is exepected to be ETH_HLEN in flow-dissection
and hash-calculation in RPS in rx path, and since the header pointer fix
is needed only in tx path, set the appropriate network header on forwarding
packets.

Fix this by accounting for the call to prealloc_data_structs()
immediately _before_ the call as opposed to after. This is needed
because it is possible to break out of the control loop after the call
to prealloc_data_structs() but before prealloc_used was set to true.

This reverts commit 386cb7cdee.
Taking the wake_worker() out of free_migration() will slow writeback
dramatically, and hence adaptability.
Say we have 10k blocks that need writing back, but are only able to
issue 5 concurrently due to the migration bandwidth: it's imperative
that we wake_worker() immediately after migration completion; waiting
for the next 1 second wake up (via do_waker) means it'll take a long
time to write that all back.

stmmac clean up for 4.3 part2
This patch set creates proper probe functions in the remaining
dwmac-* drivers, lets the drivers manage their own of match data
structure, and cleans up some of the drivers a bit. Note that
should be no functional change in any of the drivers.
First patch from Fengguang fixes a Coccinelle that was found after
the previous patch set when into next.
Probe functions are best placed just above the platform_driver
struct since it usually needs to call other functions in the
driver but this requires some code movement in the drivers. To
keep the conversion itself easier to review the code movement is
done in separate patches. This creates some extra churn but I
think it's worth it in this case.
As only a couple of drivers actually needs to use of match data
this pushed down from stmmac_platform and into the drivers. This
also makes it possible for drivers to have their own match data
structure. dwmac-rk benefits most from this.
After each driver has it's own probe function and manages it's
own match data the setup/free hooks and common match data struct
are removed.
Sorry for the slightly largish patch set this time around.
Since I can only test the core changes on my platform and not the
specific dwmac-drivers I greatly appreciate if people could test
this on their respective platforms. I did spend quite a bit of
time visually checking all these patches, but nothing beats real
hardware testing. Thanks!

This notification causes the FIB to be updated, which is not needed
because the address already exists, and more importantly it may undo
intentional changes that were made to the FIB after the address was
originally added. (As a point of comparison, when an address becomes
deprecated because its preferred lifetime expired, a notification on
this chain is not generated.)
The motivation for this commit is fixing an incompatibility between
DHCP clients which set and update the address lifetime according to
the lease, and a commercial VPN client which replaces kernel routes
in a way that outbound traffic is sent only through the tunnel (and
disconnects if any further route changes are detected via netlink).

These should be handled only by the respective STP which is in control.
They become problematic for devices with limited resources with many
ports because the hold_timer is per port and fires each second and the
hello timer fires each 2 seconds even though it's global. While in
user-space STP mode these timers are completely unnecessary so it's better
to keep them off.
Also ensure that when the bridge is up these timers are started only when

We don't log remote attribute contents, and instead write them
synchronously before we commit the block allocation and attribute
tree update transaction. As a result we are writing to the allocated
space before the allcoation has been made permanent.
As a result, we cannot consider this allocation to be a metadata
allocation. Metadata allocation can take blocks from the free list
and so reuse them before the transaction that freed the block is
committed to disk. This behaviour is perfectly fine for journalled
metadata changes as log recovery will ensure the free operation is
replayed before the overwrite, but for remote attribute writes this
is not the case.
Hence we have to consider the remote attribute blocks to contain
data and allocate accordingly. We do this by dropping the
XFS_BMAPI_METADATA flag from the block allocation. This means the
allocation will not use blocks that are on the busy list without
first ensuring that the freeing transaction has been committed to
disk and the blocks removed from the busy list. This ensures we will
never overwrite a freed block without first ensuring that it is
really free.

In recent testing, a system that crashed failed log recovery on
restart with a bad symlink buffer magic number:
XFS (vda): Starting recovery (logdev: internal)
XFS (vda): Bad symlink block magic!
XFS: Assertion failed: 0, file: fs/xfs/xfs_log_recover.c, line: 2060
On examination of the log via xfs_logprint, none of the symlink
buffers in the log had a bad magic number, nor were any other types
of buffer log format headers mis-identified as symlink buffers.
Tracing was used to find the buffer the kernel was tripping over,
and xfs_db identified it's contents as:
000: 5841524d 00000000 00000346 64d82b48 8983e692 d71e4680 a5f49e2c b317576e

.....
This is a remote attribute buffer, which are notable in that they
are not logged but are instead written synchronously by the remote
attribute code so that they exist on disk before the attribute
transactions are committed to the journal.
The above remote attribute block has an invalid LSN in it - cycle
0xd002000, block 0 - which means when log recovery comes along to
determine if the transaction that writes to the underlying block
should be replayed, it sees a block that has a future LSN and so
does not replay the buffer data in the transaction. Instead, it
validates the buffer magic number and attaches the buffer verifier
to it. It is this buffer magic number check that is failing in the
above assert, indicating that we skipped replay due to the LSN of
the underlying buffer.
The problem here is that the remote attribute buffers cannot have a
valid LSN placed into them, because the transaction that contains
the attribute tree pointer changes and the block allocation that the
attribute data is being written to hasn't yet been committed. Hence
the LSN field in the attribute block is completely unwritten,
thereby leaving the underlying contents of the block in the LSN
field. It could have any value, and hence a future overwrite of the
block by log recovery may or may not work correctly.
Fix this by always writing an invalid LSN to the remote attribute
block, as any buffer in log recovery that needs to write over the
remote attribute should occur. We are protected from having old data
written over the attribute by the fact that freeing the block before
the remote attribute is written will result in the buffer being
marked stale in the log and so all changes prior to the buffer stale
transaction will be cancelled by log recovery.
Hence it is safe to ignore the LSN in the case or synchronously
written, unlogged metadata such as remote attribute blocks, and to
ensure we do that correctly, we need to write an invalid LSN to all
remote attribute blocks to trigger immediate recovery of metadata
that is written over the top.
As a further protection for filesystems that may already have remote
attribute blocks with bad LSNs on disk, change the log recovery code
to always trigger immediate recovery of metadata over remote
attribute blocks.

When modifying the patch series to handle the XFS MMAP_LOCK nesting
of page faults, I botched the conversion of the read page fault
path, and so it is only every calling through the page cache. Re-add
the necessary __dax_fault() call for such files.
Because the get_blocks callback on read faults may not set up the
mapping buffer correctly to allow unwritten extent completion to be
run, we need to allow callers of __dax_fault() to pass a null
complete_unwritten() callback. The DAX code always zeros the
unwritten page when it is read faulted so there are no stale data
exposure issues with not doing the conversion. The only downside
will be the potential for increased CPU overhead on repeated read
faults of the same page. If this proves to be a problem, then the
filesystem needs to fix it's get_block callback and provide a
convert_unwritten() callback to the read fault path.

Merge tag 'arm64-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux
Pull arm64 fix from Catalin Marinas:
"Fix buffer overflow when UTF-16 UEFI vendor string is copied from the
system table into a char array with a size of 100 bytes"
* tag 'arm64-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux:
arm64/efi: map the entire UEFI vendor string before reading it
Pull AVR32 fix from Hans-Christian Egtvedt.
* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/egtvedt/linux-avr32:
avr32: handle NULL as a valid clock object
This reverts commit 7d01cd261c because
with given FRAME_MAXSIZE of 257 the check will never trigger and it
causes warnings from GCC (with -Wtype-limits). Also the check was
incorrect as it was not accounting for the already read 2 bytes of data
stored in the buffer.
