Pull integrity updates from James Morris:
"This contains a mixture of bug fixes, code cleanup, and new
functionality. Of note is the integrity cache locking fix, file change
detection, and support for a new EVM portable and immutable signature
type.
The re-introduction of the integrity cache lock (iint) fixes the
problem of attempting to take the i_rwsem shared a second time, when
it was previously taken exclusively. Defining atomic flags resolves
the original iint/i_rwsem circular locking - accessing the file data
vs. modifying the file metadata. Although it fixes the O_DIRECT
problem as well, a subsequent patch is needed to remove the explicit
O_DIRECT prevention.
For performance reasons, detecting when a file has changed and needs
to be re-measured, re-appraised, and/or re-audited, was limited to
after the last writer has closed, and only if the file data has
changed. Detecting file change is based on i_version. For filesystems
that do not support i_version, remote filesystems, or userspace
filesystems, the file was measured, appraised and/or audited once and
never re-evaluated. Now local filesystems, which do not support
i_version or are not mounted with the i_version option, assume the
file has changed and are required to re-evaluate the file. This change
does not address detecting file change on remote or userspace
filesystems.
Unlike file data signatures, which can be included and distributed in
software packages (eg. rpm, deb), the existing EVM signature, which
protects the file metadata, could not be included in software
packages, as it includes file system specific information (eg. i_ino,
possibly the UUID). This pull request defines a new EVM portable and
immutable file metadata signature format, which can be included in
software packages"

Core changes:
- Disallow open drain and open source flags to be set
simultaneously. This doesn't make electrical sense, and would
the hardware actually respond to this setting, the result
would be short circuit.
- ACPI GPIO has a new core infrastructure for handling quirks.
The quirks are there to deal with broken ACPI tables centrally
instead of pushing the work to individual drivers. In the world
of BIOS writers, the ACPI tables are perfect. Until they find a
mistake in it. When such a mistake is found, we can patch it
with a quirk. It should never happen, the problem is that it
happens. So we accomodate for it.
- Several documentation updates.
- Revert the patch setting up initial direction state from
reading the device. This was causing bad things for drivers
that can't read status on all its pins. It is only affecting
debugfs information quality.
- Label descriptors with the device name if no explicit label is
passed in.
- Pave the ground for transitioning SPI and regulators to use
GPIO descriptors by implementing some quirks in the device tree
GPIO parsing code.
New drivers:
- New driver for the Access PCIe IDIO 24 family.
Other:
- Major refactorings and improvements to the GPIO mockup driver
used for test and verification.
- Moved the AXP209 driver over to pin control since it gained a
pin control back-end. These patches will appear (with the same
hashes) in the pin control pull request as well.
- Convert the onewire GPIO driver w1-gpio to use descriptors.
This is merged here since the W1 maintainers send very few
pull requests and he ACKed it.
- Start to clean up driver headers using <linux/gpio.h> to just
use <linux/gpio/driver.h> as appropriate.

This pull requests contains a consolidation of the generic no-IOMMU code,
a well as the glue code for swiotlb. All the code is based on the x86
implementation with hooks to allow all architectures that aren't cache
coherent to use it. The x86 conversion itself has been deferred because
the x86 maintainers were a little busy in the last months.

This is mostly updates of the usual driver suspects: arcmsr,
scsi_debug, mpt3sas, lpfc, cxlflash, qla2xxx, aacraid, megaraid_sas,
hisi_sas. We also have a rework of the libsas hotplug handling to
make it more robust, a slew of 32 bit time conversions and fixes, and
a host of the usual minor updates and style changes. The biggest
potential for regressions is the libsas hotplug changes, but so far
they seem stable under testing.

(e.g. reduced memory footprint as well leveraging per-bio-data more).
- Introduce new bio-based mode (DM_TYPE_NVME_BIO_BASED) that leverages
the more direct IO submission path in the block layer; this mode is
used by DM multipath and also optimizes targets like DM thin-pool that
stack directly on NVMe data device.

(e.g. scsi_dh) code paths to allow for more optimized support for NVMe
multipath.
- A fix for DM multipath path selectors (service-time and queue-length)
to select paths in a more balanced way; largely academic but doesn't
hurt.
- Numerous DM raid target fixes and improvements.
- Add a new DM "unstriped" target that enables Intel to workaround
firmware limitations in some NVMe drives that are striped internally

Merge tag 'xfs-4.16-merge-4' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux
Pull xfs updates from Darrick Wong:
"This merge cycle, we're again some substantive changes to XFS.
Metadata verifiers have been restructured to provide more detail about
which part of a metadata structure failed checks, and we've enhanced
the new online fsck feature to cross-reference extent allocation
information with the other metadata structures. With this pull, the
metadata verification part of online fsck is more or less finished,
though the feature is still experimental and still disabled by
default.
We're also preparing to remove the EXPERIMENTAL tag from a couple of
features this cycle. This week we're committing a bunch of space
accounting fixes for reflink and removing the EXPERIMENTAL tag from
reflink; I anticipate that we'll be ready to do the same for the
reverse mapping feature next week. (I don't have any pending fixes for
rmap; however I wish to remove the tags one at a time.)
This giant pile of patches has been run through a full xfstests run
over the weekend and through a quick xfstests run against this
morning's master, with no major failures reported. Let me know if
there's any merge problems -- git merge reported that one of our
patches touched the same function as the i_version series, but it
resolved things cleanly.
Summary:
- Log faulting code locations when verifiers fail, for improved
diagnosis of corrupt filesystems.
- Implement metadata verifiers for local format inode fork data.
- Online scrub now cross-references metadata records with other
metadata.
- Refactor the fs geometry ioctl generation functions.
- Harden various metadata verifiers.
- Fix various accounting problems.
- Fix uncancelled transactions leaking when xattr functions fail.
- Prevent the copy-on-write speculative preallocation garbage

five categories: (1) code cleanups, (2) patches related to adding
PUNCH_HOLE support to GFS2, (3) support for new fields in resource group
headers, (4) a few bug fixes, and (5) support for new fields in journal
log headers. These new fields, which were previously unused, are designed
to make it easier to track down file system corruption, and allow fsck.gfs2
to make more intelligent decisions when finding and fixing file system
corruption.

of the previous patches.
14. Andreas contributed a patch to add fallocate with PUNCH_HOLE.
15. Andreas fixed some typos in the comments.
16. Andreas added function gfs2_max_stuffed_size to replace a piece
of code that was needlessly repeated throughout GFS2.
17. Andreas made a minor cleanup to function gfs2_page_add_databufs.
18. Andreas got rid of function gfs2_log_header_in in preparation for
the new log header fields.
19. Andreas also fixed up some missing newlines in kernel messages.
20. Andy Price added a new field to resource groups to indicate where
the next one should be, to allow fsck.gfs2 to make better repairs.
21. Andy also added new rindex fields for consistency checking.
22. Andy added a crc field to resource group headers for consistency
checking.
23. I added a patch to reduce redundancy in functions common to

on a prototype from Steve Whitehouse.
26. I added a patch to log the source of journal log headers so we
can better track down journal corruption.
27. I added a patch to fix a minor comment typo.

Merge tag 'gfs2-4.16.fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/gfs2/linux-gfs2
Pull GFS2 updates from Bob Peterson:
"We've got 30 patches for this merge window. These generally fall into
five categories:
- code cleanups
- patches related to adding PUNCH_HOLE support to GFS2
- support for new fields in resource group headers
- a few bug fixes
- support for new fields in journal log headers. These new fields,
which were previously unused, are designed to make it easier to
track down file system corruption, and allow fsck.gfs2 to make more
intelligent decisions when finding and fixing file system
corruption.
Details:
- Two patches from Abhi Das, to trim the ordered writes list, which
used to grow uncontrollably until unmount.
- Several patches from Andreas Gruenbacher: remove an unused
parameter from function gfs2_write_jdata_pagevec, remove a
pointless BUG_ON, clean up an error patch in trunc_start, remove
some unused parameters from truncate, make gfs2_journaled_truncate
more efficient, clean up the support functions for truncate, fix
metadata read-ahead for truncate to make it faster, fix up the
non-recursive truncate code, rework and rename
gfs2_block_truncate_page, generalize the non-recursive truncate
code so it can take a range of values for punch_hole support,
introduce new PUNCH_HOLE support that take advantage of the
previous patches, add fallocate support with PUNCH_HOLE, fix some
typos in the comments, add the function gfs2_max_stuffed_size to
replace a piece of code that was needlessly repeated throughout
GFS2, a minor cleanup to function gfs2_page_add_databufs, get rid
of function gfs2_log_header_in in preparation for the new log
header fields, and also fix up some missing newlines in kernel
messages.
- Andy Price added a new field to resource groups to indicate where
the next one should be, to allow fsck.gfs2 to make better repairs.
He also added new rindex fields for consistency checking, and added
a crc field to resource group headers for consistency checking.
- I reduced redundancy in functions common to freeing dinodes, and
when writing log headers between the journalling code and journal
recovery code. Also added new fields to journal log headers based
on a prototype from Steve Whitehouse, and log the source of journal
log headers so we can better track down journal corruption. Minor
comment typo fix and a fix for a BUG in an unlink error path.
- Steve Whitehouse contributed a patch to fix an incorrect use of the
gfs2_blk2rgrpd function.
- Tetsuo Handa contributed a patch that fixes incorrect error
handling in function init_gfs2_fs"

As Linus points out:
The inode_cmp_iversion{+raw}() functions are pure and utter crap.
Why?
You say that they return 0/negative/positive, but they do so in a
completely broken manner. They return that ternary value as the
sequence number difference in a 's64', which means that if you
actually care about that ternary value, and do the *sane* thing that
the kernel-doc of the function implies is the right thing, you would
do
int cmp = inode_cmp_iversion(inode, old);
if (cmp < 0 ...
and as a result you get code that looks sane, but that doesn't
actually *WORK* right.
Since none of the callers actually care about the ternary value here,
convert the inode_cmp_iversion{+raw} functions to just return a boolean
value (false for matching, true for non-matching).
This matches the existing use of these functions just fine, and makes it
simple to convert them to return a ternary value in the future if we
grow callers that need it.
With this change we can also reimplement inode_cmp_iversion in a simpler
way using inode_peek_iversion.

The problem, as Florian noted, is that nf_setsockopt() is always
called with the socket held, even if the lock itself is required only
for very tight scopes and only for some operation.
This patch addresses the issues moving the lock_sock() call only
where really needed, namely in ipv*_getorigdst(), so that nf_setsockopt()
does not need anymore to acquire both locks.

Add suffix ULL to constant 80000 in order to avoid a potential integer
overflow and give the compiler complete information about the proper
arithmetic to use. Notice that this constant is used in a context that
expects an expression of type u64.
The current cast to u64 effectively applies to the whole expression
as an argument of type u64 to be passed to div64_u64, but it does
not prevent it from being evaluated using 32-bit arithmetic instead
of 64-bit arithmetic.
Also, once the expression is properly evaluated using 64-bit arithmentic,
there is no need for the parentheses and the external cast to u64.

- Backwards Compatibility:
If userspace wants to determine whether RTM_NEWLINK supports the
IFLA_IF_NETNSID property they should first send an RTM_GETLINK request
with IFLA_IF_NETNSID on lo. If either EACCESS is returned or the reply
does not include IFLA_IF_NETNSID userspace should assume that
IFLA_IF_NETNSID is not supported on this kernel.
If the reply does contain an IFLA_IF_NETNSID property userspace
can send an RTM_NEWLINK with a IFLA_IF_NETNSID property. If they receive
EOPNOTSUPP then the kernel does not support the IFLA_IF_NETNSID property
with RTM_NEWLINK. Userpace should then fallback to other means.
