Notice that
const struct of_device_id of_mtk_match[] = {

As Hongjun/Nicolas summarized in their original patch:
"
When a device changes from one netns to another, it's first unregistered,
then the netns reference is updated and the dev is registered in the new
netns. Thus, when a slave moves to another netns, it is first
unregistered. This triggers a NETDEV_UNREGISTER event which is caught by
the bonding driver. The driver calls bond_release(), which calls
dev_set_mtu() and thus triggers NETDEV_CHANGEMTU (the device is still in
the old netns).
"
This is a very special case, because the device is being unregistered
no one should still care about the NETDEV_CHANGEMTU event triggered
at this point, we can avoid broadcasting this event on this path,
and avoid touching inetdev_event()/addrconf_notify() path.
It requires to export __dev_set_mtu() to bonding driver.

sock_graft() unilaterally sets up parent->sk based on the
assumption that the existing parent->sk is null. If this
condition is not true, then the existing parent->sk would
be leaked, so add a WARN_ON() to alert callers who may fall
in this category.

There are two problems with calling sock_create_kern() from
rds_tcp_accept_one()
1. it sets up a new_sock->sk that is wasteful, because this ->sk
is going to get replaced by inet_accept() in the subsequent ->accept()
2. The new_sock->sk is a leaked reference in sock_graft() which
expects to find a null parent->sk
Avoid these problems by calling sock_create_lite().

As per the SAMA5D3 device specification it supports Jumbo frames.
But the suggested flag and length of bytes it supports was not updated
in this driver config_structure.
The maximum jumbo frames the device supports :
10240 bytes as per the device spec.
While changing the MTU value greater than 1500, it threw error:
sudo ifconfig eth1 mtu 9000
SIOCSIFMTU: Invalid argument
Add this support to driver so that it works as expected and designed.

Pull iov_iter hardening from Al Viro:
"This is the iov_iter/uaccess/hardening pile.
For one thing, it trims the inline part of copy_to_user/copy_from_user
to the minimum that *does* need to be inlined - object size checks,
basically. For another, it sanitizes the checks for iov_iter
primitives. There are 4 groups of checks: access_ok(), might_fault(),
object size and KASAN.
- access_ok() had been verified by whoever had set the iov_iter up.
However, that has happened in a function far away, so proving that
there's no path to actual copying bypassing those checks is hard
and proving that iov_iter has not been buggered in the meanwhile is
also not pleasant. So we want those redone in actual
copyin/copyout.
- might_fault() is better off consolidated - we know whether it needs
to be checked as soon as we enter iov_iter primitive and observe
the iov_iter flavour. No need to wait until the copyin/copyout. The
call chains are short enough to make sure we won't miss anything -
in fact, it's more robust that way, since there are cases where we
do e.g. forced fault-in before getting to copyin/copyout. It's not
quite what we need to check (in particular, combination of
iovec-backed and set_fs(KERNEL_DS) is almost certainly a bug, not a
cause to skip checks), but that's for later series. For now let's
keep might_fault().
- KASAN checks belong in copyin/copyout - at the same level where
other iov_iter flavours would've hit them in memcpy().
- object size checks should apply to *all* iov_iter flavours, not
just iovec-backed ones.
There are two groups of primitives - one gets the kernel object
described as pointer + size (copy_to_iter(), etc.) while another gets
it as page + offset + size (copy_page_to_iter(), etc.)
For the first group the checks are best done where we actually have a
chance to find the object size. In other words, those belong in inline
wrappers in uio.h, before calling into iov_iter.c. Same kind as we
have for inlined part of copy_to_user().
For the second group there is no object to look at - offset in page is
just a number, it bears no type information. So we do them in the
common helper called by iov_iter.c primitives of that kind. All it
currently does is checking that we are not trying to access outside of
the compound page; eventually we might want to add some sanity checks
on the page involved.
So the things we need in copyin/copyout part of iov_iter.c do not
quite match anything in uaccess.h (we want no zeroing, we *do* want
access_ok() and KASAN and we want no might_fault() or object size
checks done on that level). OTOH, these needs are simple enough to
provide a couple of helpers (static in iov_iter.c) doing just what we
need..."

Pull Writeback error handling updates from Jeff Layton:
"This pile represents the bulk of the writeback error handling fixes
that I have for this cycle. Some of the earlier patches in this pile
may look trivial but they are prerequisites for later patches in the
series.
The aim of this set is to improve how we track and report writeback
errors to userland. Most applications that care about data integrity
will periodically call fsync/fdatasync/msync to ensure that their
writes have made it to the backing store.
For a very long time, we have tracked writeback errors using two flags
in the address_space: AS_EIO and AS_ENOSPC. Those flags are set when a
writeback error occurs (via mapping_set_error) and are cleared as a
side-effect of filemap_check_errors (as you noted yesterday). This
model really sucks for userland.
Only the first task to call fsync (or msync or fdatasync) will see the
error. Any subsequent task calling fsync on a file will get back 0
(unless another writeback error occurs in the interim). If I have
several tasks writing to a file and calling fsync to ensure that their
writes got stored, then I need to have them coordinate with one
another. That's difficult enough, but in a world of containerized
setups that coordination may even not be possible.
But wait...it gets worse!
The calls to filemap_check_errors can be buried pretty far down in the
call stack, and there are internal callers of filemap_write_and_wait
and the like that also end up clearing those errors. Many of those
callers ignore the error return from that function or return it to
userland at nonsensical times (e.g. truncate() or stat()). If I get
back -EIO on a truncate, there is no reason to think that it was
because some previous writeback failed, and a subsequent fsync() will
(incorrectly) return 0.
This pile aims to do three things:
1) ensure that when a writeback error occurs that that error will be
reported to userland on a subsequent fsync/fdatasync/msync call,
regardless of what internal callers are doing
2) report writeback errors on all file descriptions that were open at
the time that the error occurred. This is a user-visible change,
but I think most applications are written to assume this behavior
anyway. Those that aren't are unlikely to be hurt by it.
3) document what filesystems should do when there is a writeback
error. Today, there is very little consistency between them, and a
lot of cargo-cult copying. We need to make it very clear what
filesystems should do in this situation.
To achieve this, the set adds a new data type (errseq_t) and then
builds new writeback error tracking infrastructure around that. Once
all of that is in place, we change the filesystems to use the new
infrastructure for reporting wb errors to userland.
Note that this is just the initial foray into cleaning up this mess.
There is a lot of work remaining here:
1) convert the rest of the filesystems in a similar fashion. Once the
initial set is in, then I think most other fs' will be fairly
simple to convert. Hopefully most of those can in via individual
filesystem trees.
2) convert internal waiters on writeback to use errseq_t for
detecting errors instead of relying on the AS_* flags. I have some
draft patches for this for ext4, but they are not quite ready for
prime time yet.
This was a discussion topic this year at LSF/MM too. If you're

This fixes a regression introduced by a patch we did in mid-2015
(commit 88ffbf3e037e: "GFS2: Use resizable hash table for glocks"), so
best to get it fixed. Some code was reverted that should not have
been.
The patch from Andreas Gruenbacher just re-adds code that had been
there originally"

take_dentry_name_snapshot() takes a safe snapshot of dentry name;
if the name is a short one, it gets copied into caller-supplied
structure, otherwise an extra reference to external name is grabbed
(those are never modified). In either case the pointer to stable
string is stored into the same structure.
dentry must be held by the caller of take_dentry_name_snapshot(),
but may be freely dropped afterwards - the snapshot will stay
until destroyed by release_dentry_name_snapshot().
Intended use:
struct name_snapshot s;
take_dentry_name_snapshot(&s, dentry);
...
access s.name
...
release_dentry_name_snapshot(&s);
Replaces fsnotify_oldname_...(), gets used in fsnotify to obtain the name
to pass down with event.

Pull Kbuild thin archives updates from Masahiro Yamada:
"Thin archives migration by Nicholas Piggin.
THIN_ARCHIVES has been available for a while as an optional feature
only for PowerPC architecture, but we do not need two different
intermediate-artifact schemes.
Using thin archives instead of conventional incremental linking has
various advantages:
- save disk space for builds
- speed-up building a little
- fix some link issues (for example, allyesconfig on ARM) due to more
flexibility for the final linking
- work better with dead code elimination we are planning
As discussed before, this migration has been done unconditionally so
that any problems caused by this will show up with "git bisect".
With testing with 0-day and linux-next, some architectures actually
showed up problems, but they were trivial and all fixed now"

Converting kselftest output to standard format will help identify
run to run differences and pin point failures easily. TAP13 format
has been in use for several years and the output is human friendly.
Please find the specification:
https://testanything.org/tap-version-13-specification.html
Credit goes to Tim Bird for recommending TAP13 as a suitable
format, and to Grag KH for kick starting the work with help from
Paul Elder and Alice Ferrazzi
The first phase of the TAp13 conversion is included in this update.
Future updates will include updates to rest of the tests.
- Masami Hiramatsu fixed ftrace to run on 4.9 stable kernels.
- Kselftest documnetation has been converted to ReST format. Document
now has a new home under Documentation/dev-tools.

Michael Ellerman reported that commit 8c6657cb50cb ("Switch flock
copyin/copyout primitives to copy_{from,to}_user()") broke his
networking on a bunch of PPC machines (64-bit kernel, 32-bit userspace).
The reason is a brown-paper bug by that commit, which had the arguments
to "copy_flock_fields()" in the wrong order, breaking the compat
handling for file locking. Apparently very few people run 32-bit user
space on x86 any more, so the PPC people got the honor of noticing this
"feature".
Michael also sent a minimal diff that just changed the order of the
arguments in that macro.
This is not that minimal diff.
This not only changes the order of the arguments in the macro, it also
changes them to be pointers (to be consistent with all the other uses of
those pointers), and makes the functions that do all of this also have
the proper "const" attribution on the source pointers in order to make
issues like that (using the source as a destination) be really obvious.

Pull GPIO updates from Linus Walleij:
"This is the bulk of GPIO changes for the v4.13 series.
Some administrativa:
I have a slew of 8250 serial patches and the new IOT2040 serial+GPIO
driver coming in through this tree, along with a whole bunch of Exar
8250 fixes. These are ACKed by Greg and also hit drivers/platform/*
where they are ACKed by Andy Shevchenko.
Speaking about drivers/platform/* there is also a bunch of ACPI stuff
coming through that route, again ACKed by Andy.
The MCP23S08 changes are coming in here as well. You already have the
commits in your tree, so this is just a result of sharing an immutable
branch between pin control and GPIO.
Core:
- Export add/remove for lookup tables so that modules can export GPIO
descriptor tables.
- Handle GPIO sleep states: it is now possible to flag that a GPIO
line may loose its state during suspend/resume of the system to
save power. This is used in the Wolfson Micro Arizona driver.
- ACPI-based GPIO was tightened up a lot around the edges.
- Use bitmap_fill() to speed up a loop.
New drivers:
- Exar XRA1403 SPI-based GPIO.
- MVEBU driver now supports Armada 7K and 8K.
- LP87565 PMIC GPIO.
- Renesas R-CAR R8A7743 (RZ/G1M).
- The new IOT2040 8250 serial/GPIO also comes in through this
changeset.
Substantial driver changes:
- Seriously fix the Exar 8250 GPIO portions to work.
- The MCP23S08 was moved out to a pin control driver.
- Convert MEVEBU to use regmap for register access.
- Drop Vulcan support from the Broadcom driver.
- Serious cleanup and improvement of the mockup driver, giving us a
better test coverage.
Misc:
- Lots of janitorial clean up.
- A bunch of documentation fixes"

Pull libnvdimm updates from Dan Williams:
"libnvdimm updates for the latest ACPI and UEFI specifications. This
pull request also includes new 'struct dax_operations' enabling to
undo the abuse of copy_user_nocache() for copy operations to pmem.
The dax work originally missed 4.12 to address concerns raised by Al.
Summary:
- Introduce the _flushcache() family of memory copy helpers and use
them for persistent memory write operations on x86. The
_flushcache() semantic indicates that the cache is either bypassed
for the copy operation (movnt) or any lines dirtied by the copy
operation are written back (clwb, clflushopt, or clflush).
- Extend dax_operations with ->copy_from_iter() and ->flush()
operations. These operations and other infrastructure updates allow
all persistent memory specific dax functionality to be pushed into
libnvdimm and the pmem driver directly. It also allows dax-specific
sysfs attributes to be linked to a host device, for example:
/sys/block/pmem0/dax/write_cache
- Add support for the new NVDIMM platform/firmware mechanisms
introduced in ACPI 6.2 and UEFI 2.7. This support includes the v1.2
namespace label format, extensions to the address-range-scrub
command set, new error injection commands, and a new BTT
(block-translation-table) layout. These updates support inter-OS
and pre-OS compatibility.
- Fix a longstanding memory corruption bug in nfit_test.
- Make the pmem and nvdimm-region 'badblocks' sysfs files poll(2)
capable.
- Miscellaneous fixes and small updates across libnvdimm and the nfit
driver.

====================
pull-request: mac80211 2017-07-07
Just got a set of fixes in from Jouni/QCA, all netlink validation
fixes. I assume they ran some kind of checker, but I don't know what
kind :)
Please pull and let me know if there's any problem.

validate_scan_freqs() retrieves frequencies from attributes
nested in the attribute NL80211_ATTR_SCAN_FREQUENCIES with
nla_get_u32(), which reads 4 bytes from each attribute
without validating the size of data received. Attributes
nested in NL80211_ATTR_SCAN_FREQUENCIES don't have an nla policy.
Validate size of each attribute before parsing to avoid potential buffer
overread.

Buffer overread may happen as nl80211_set_station() reads 4 bytes
from the attribute NL80211_ATTR_LOCAL_MESH_POWER_MODE without
validating the size of data received when userspace sends less
than 4 bytes of data with NL80211_ATTR_LOCAL_MESH_POWER_MODE.
Define nla_policy for NL80211_ATTR_LOCAL_MESH_POWER_MODE to avoid
the buffer overread.

nla policy checks for only maximum length of the attribute data when the
attribute type is NLA_BINARY. If userspace sends less data than
specified, cfg80211 may access illegal memory. When type is NLA_UNSPEC,
nla policy check ensures that userspace sends minimum specified length
number of bytes.
Remove type assignment to NLA_BINARY from nla_policy of
NL80211_NAN_FUNC_SERVICE_ID to make these NLA_UNSPEC and to make sure
minimum NL80211_NAN_FUNC_SERVICE_ID_LEN bytes are received from
userspace with NL80211_NAN_FUNC_SERVICE_ID.

* might_fault() is better checked in caller (and e.g. fault-in + kmap_atomic
codepath also needs might_fault() coverage)
* we have already done object size checks
* we have *NOT* done access_ok() recently enough; we rely upon the
iovec array having passed sanity checks back when it had been created
and not nothing having buggered it since. However, that's very much
non-local, so we'd better recheck that.
So the thing we want does not match anything in uaccess - we need
access_ok + kasan checks + raw copy without any zeroing. Just define
such helpers and use them here.
