Fix possibly wrong memcpy() bytes length since some CAN records received from
PCAN-USB could define a DLC field in range [9..15].
In that case, the real DLC value MUST be used to move forward the record pointer
but, only 8 bytes max. MUST be copied into the data field of the struct
can_frame object of the skb given to the network core.

ALSA: usb-audio: do not trust too-big wMaxPacketSize values

Currently the conntrack checks if the ending sequence of a packet
falls within the observed receive window. However it does so even
if it has not observe any packet from the remote yet and uses an
uninitialized receive window (td_maxwin).
If a connection uses Fast Open to send a SYN-data packet which is
dropped afterward in the network. The subsequent SYNs retransmits
will all fail this check and be discarded, leading to a connection
timeout. This is because the SYN retransmit does not contain data
payload so
end == initial sequence number (isn) + 1
sender->td_end == isn + syn_data_len
receiver->td_maxwin == 0
The fix is to only apply this check after td_maxwin is initialized.

When btrfs readdir() hits the last entry it sets the readdir offset to a
huge value to stop buggy apps from breaking when the same name is
returned by readdir() with concurrent rename()s.
But unconditionally setting the offset to INT_MAX causes readdir() to
loop returning any entries with offsets past INT_MAX. It only takes a
few hours of constant file creation and removal to create entries past
INT_MAX.
So let's set the huge offset to LLONG_MAX if the last entry has already
overflowed 32bit loff_t. Without large offsets behaviour is identical.
With large offsets 64bit apps will work and 32bit apps will be no more
broken than they currently are if they see large offsets.

The ceph guys tripped over this bug where we were still holding onto the
original path that we used to copy the inode with when logging. This is based
on Chris's fix which was reported to fix the problem. We need to drop the paths
in two cases anyway so just move the drop up so that we don't have duplicate
code. Thanks,

I noticed while running multi-threaded fsync tests that sometimes fsck would
complain about an improper gap. This happens because we fail to add a hole
extent to the file, which was happening when we'd split a hole EM because
btrfs_drop_extent_cache was just discarding the whole em instead of splitting
it. So this patch fixes this by allowing us to split a hole em properly, which
means that added holes actually get logged properly and we no longer see this
fsck error. Thankfully we're tolerant of these sort of problems so a user would
not see any adverse effects of this bug, other than fsck complaining. Thanks,

Because we don't mess with the offset into the extent for compressed we will
properly find both extents for this case
[extent a][extent b][rest of extent a]
but because we already added a ref for the front half we won't add the inode
information for the second half. This causes us to leak that memory and not
print out the other offset when we do logical-resolve. So fix this by calling
ulist_add_merge and then add our eie to the existing entry if there is one.
With this patch we get both offsets out of logical-resolve. With this and the
other 2 patches I've sent we now pass btrfs/276 on my vm with compress-force=lzo
set. Thanks,

If you do btrfs inspect-internal logical-resolve on a compressed extent that has
been partly overwritten it won't find anything. This is because we try and
match the extent offset we've searched for based on the extent offset in the
data extent entry. However this doesn't work for compressed extents because the
offsets are for the uncompressed size, not the compressed size. So instead only
do this check if we are not compressed, that way we can get an actual entry for
the physical offset rather than nothing for compressed. Thanks,

xfstest btrfs/276 was freaking out on slower boxes partly because fiemap was
offsetting the physical based on the extent offset. This is perfectly fine with
uncompressed extents, however the extent offset is into the uncompressed area,
not the compressed. So we can return a physical value that isn't at all within
the area we have allocated on disk. Fix this by returning the start of the
extent if it is compressed no matter what the offset. Thanks,

For partial extents, snapshot-aware defrag does not work as expected,
since
a) we use the wrong logical offset to search for parents, which should be
disk_bytenr + extent_offset, not just disk_bytenr,
b) 'offset' returned by the backref walking just refers to key.offset, not
the 'offset' stored in btrfs_extent_data_ref which is
(key.offset - extent_offset).
The reproducer:
$ mkfs.btrfs sda
$ mount sda /mnt
$ btrfs sub create /mnt/sub
$ for i in `seq 5 -1 1`; do dd if=/dev/zero of=/mnt/sub/foo bs=5k count=1 seek=$i conv=notrunc oflag=sync; done
$ btrfs sub snap /mnt/sub /mnt/snap1
$ btrfs sub snap /mnt/sub /mnt/snap2
$ sync; btrfs filesystem defrag /mnt/sub/foo;
$ umount /mnt
$ btrfs-debug-tree sda (Here we can check whether the defrag operation is snapshot-awared.

OpenFirmware wasn't quite following the protocol described in boot.txt
and the kernel has detected this through use of the sentinel value
in boot_params. OFW does zero out almost all of the stuff that it should
do, but not the sentinel.
This causes the kernel to clear olpc_ofw_header, which breaks x86 OLPC
support.
OpenFirmware has now been fixed. However, it would be nice if we could
maintain Linux compatibility with old firmware versions. To do that, we just
have to avoid zeroing out olpc_ofw_header.
OFW does not write to any other parts of the header that are being zapped
by the sentinel-detection code, and all users of olpc_ofw_header are
somewhat protected through checking for the OLPC_OFW_SIG magic value
before using it. So this should not cause any problems for anyone.

- ACPI-based memory hotplug stopped working after a recent change,
because it's not possible to associate sufficiently many "physical"

Fix from Rafael J Wysocki removes that limit and makes memory
hotplug work again.

- Fix breakage resulting from a mistake made in 3.9 and causing the
detection of some graphics adapters (that were detected correctly
before) to fail. There are two objects representing the same PCIe
port in the affected systems' ACPI tables and both appear as
"enabled" and we are expected to guess which one to use. We used
to choose the right one before by pure luck, but when we tried to
address another similar corner case, the luck went away. This time
we try to make our guessing a bit more educated which is reported
to work on those systems.
- The /proc/acpi/wakeup interface code is missing some locking
which may lead to breakage if that file is written or read during
hotplug of wakeup devices. That should be rare but still possible,
so it's better to start using the appropriate locking there.

vxlan: add necessary locking on device removal
The problem is that vxlan_dellink(), which is called with RTNL lock
held, tries to flush the workqueue synchronously, but apparently
igmp_join and igmp_leave work need to hold RTNL lock too, therefore we
have a soft lockup!
As suggested by Stephen, probably the flush_workqueue can just be
removed and let the normal refcounting work. The workqueue has a
reference to device and socket, therefore the cleanups should work
correctly.
