This needs to use xt_unregister_targets, else new revision is left
on the list which then causes list to point to a target struct that has been free'd.

Dan Carpenter points out that deref occurs after NULL check, we should

If net namespace is exiting while nf_tables module is being removed
we can oops:
BUG: unable to handle kernel NULL pointer dereference at 0000000000000040
IP: nf_tables_flowtable_event+0x43/0xf0 [nf_tables]
PGD 0 P4D 0

Avoid this by attempting to take reference on the net namespace from
the notifiers. If it fails the namespace is exiting already, and nft
core is taking care of cleanup work.
We also need to make sure the netdev hook type gets removed
before netns ops removal, else notifier might be invoked with device
event for a netns where net->nft was never initialised (because
pernet ops was removed beforehand).

We must first remove the nfnetlink protocol handler when nf_tables module
is unloaded -- we don't want userspace to submit new change requests once
we've started to tear down nft state.
Furthermore, nfnetlink must not call any subsystem function after
call_batch returned -EAGAIN.
EAGAIN means the subsys mutex was dropped, so its unlikely but possible that
nf_tables subsystem was removed due to 'rmmod nf_tables' on another cpu.
Therefore, we must abort batch completely and not move on to next part of
the batch.
Last, we can't invoke ->abort unless we've checked that the subsystem is
still registered.
Change netns exit path of nf_tables to make sure any incompleted
transaction gets removed on exit.

====================
Intel Wired LAN Driver Updates 2018-06-11
This series contains fixes to ixgbe IPsec and MACVLAN.
Alex provides the 5 fixes in this series, starting with fixing an issue
where num_rx_pools was not being populated until after the queues and
interrupts were reinitialized when enabling MACVLAN interfaces. Updated
to use CONFIG_XFRM_OFFLOAD instead of CONFIG_XFRM, since the code
requires CONFIG_XFRM_OFFLOAD to be enabled. Moved the IPsec
initialization function to be more consistent with the placement of
similar initialization functions and before the call to reset the
hardware, which will clean up any link issues that may have been
introduced. Fixed the boolean logic that was testing for transmit OR
receive ready bits, when it should have been testing for transmit AND
receive ready bits. Fixed the bit definitions for SECTXSTAT and SECRXSTAT
registers and ensure that if IPsec is disabled on the part, do not
enable it.

Debugging further, it turns out that calling into ctx->sk_poll() is
invalid since sk_poll itself is NULL which was saved from the original
TCP socket in order for tls_sw_poll() to invoke it.
Looks like the recent conversion from poll to poll_mask callback started
in 152524231023 ("net: add support for ->poll_mask in proto_ops") missed
to eventually convert kTLS, too: TCP's ->poll was converted over to the
->poll_mask in commit 2c7d3dacebd4 ("net/tcp: convert to ->poll_mask")
and therefore kTLS wrongly saved the ->poll old one which is now NULL.
Convert kTLS over to use ->poll_mask instead. Also instead of POLLIN |
POLLRDNORM use the proper EPOLLIN | EPOLLRDNORM bits as the case in
tcp_poll_mask() as well that is mangled here.

This patch fixes two issues. First we add an early test for the Tx and Rx
security block ready bits. By doing this we can avoid the need for waits or
loopback in the event that the security block is already flushed out.
Secondly we fix the boolean logic that was testing for the Tx OR Rx ready
bits being set and change it so that we only exit if the Tx AND Rx ready
bits are both set.

This patch moves the IPsec init function in ixgbe_sw_init. This way it is a
bit more consistent with the placement of similar initialization functions
and is placed before the reset_hw call which should allow us to clean up
any link issues that may be introduced by the fact that we force the link
up if somehow the device had IPsec still enabled before the driver was
loaded.
In addition to the function move it is necessary to change the assignment
of netdev->features. The easiest way to do this is to just test for the
existence of adapter->ipsec and if it is present we set the feature bits.

There is no point in adding code if CONFIG_XFRM is defined that we won't
use unless CONFIG_XFRM_OFFLOAD is defined. So instead of leaving this code
floating around I am replacing the ifdef with what I believe is the correct
one so that we only include the code and variables if they will actually be
used.

When we were enabling macvlan interfaces we weren't correctly configuring
things until ixgbe_setup_tc was called a second time either by tweaking the
number of queues or increasing the macvlan count past 15.
The issue came down to the fact that num_rx_pools is not populated until
after the queues and interrupts are reinitialized.
Instead of trying to set it sooner we can just move the call to setup at
least 1 traffic class to the SR-IOV/VMDq setup function so that we just set
it for this one case. We already had a spot that was configuring the queues
for TC 0 in the code here anyway so it makes sense to also set the number
of TCs here as well.

larger than the maximum possible receive buffer. Such values
mute POLLIN signals on the socket which can stall progress

DP83620 register set is compatible with the DP83848, but it also supports
100base-FX. When the hardware is configured such as that fiber mode is
enabled, autonegotiation is not possible.
The chip, however, doesn't expose this information via BMSR_ANEGCAPABLE.
Instead, this bit is always set high, even if the particular hardware
configuration makes it so that auto negotiation is not possible [1]. Under
these circumstances, the phy subsystem keeps trying for autonegotiation to
happen, without success.
Hereby, we inspect BMCR_ANENABLE bit after genphy_config_init, which on
reset is set to 0 when auto negotiation is disabled, and so we use this
value instead of BMSR_ANEGCAPABLE.

fchownat() doesn't even hold refcnt of fd until it figures out
fd is really needed (otherwise is ignored) and releases it after
it resolves the path. This means sock_close() could race with
sockfs_setattr(), which leads to a NULL pointer dereference
since typically we set sock->sk to NULL in ->release().
As pointed out by Al, this is unique to sockfs. So we can fix this
in socket layer by acquiring inode_lock in sock_close() and
checking against NULL in sockfs_setattr().
sock_release() is called in many places, only the sock_close()
path matters here. And fortunately, this should not affect normal
sock_close() as it is only called when the last fd refcnt is gone.
It only affects sock_close() with a parallel sockfs_setattr() in
progress, which is not common.

Pull x86 updates and fixes from Thomas Gleixner:
- Fix the (late) fallout from the vector management rework causing
hlist corruption and irq descriptor reference leaks caused by a
missing sanity check.
The straight forward fix triggered another long standing issue to
surface. The pre rework code hid the issue due to being way slower,
but now the chance that user space sees an EBUSY error return when
updating irq affinities is way higher, though quite a bunch of
userspace tools do not handle it properly despite the fact that EBUSY
could be returned for at least 10 years.
It turned out that the EBUSY return can be avoided completely by
utilizing the existing delayed affinity update mechanism for irq
remapped scenarios as well. That's a bit more error handling in the
kernel, but avoids fruitless fingerpointing discussions with tool
developers.
- Decouple PHYSICAL_MASK from AMD SME as its going to be required for
the upcoming Intel memory encryption support as well.
- Handle legacy device ACPI detection properly for newer platforms
- Fix the wrong argument ordering in the vector allocation tracepoint
- Simplify the IDT setup code for the APIC=n case
- Use the proper string helpers in the MTRR code
- Remove a stale unused VDSO source file

Commit a841796f11c9 ("signal: align __lock_task_sighand() irq disabling and
RCU") introduced a rcu read side critical section with interrupts
disabled. The changelog suggested that a better long-term fix would be "to
make rt_mutex_unlock() disable irqs when acquiring the rt_mutex structure's
->wait_lock".
This long-term fix has been made in commit b4abf91047cf ("rtmutex: Make
wait_lock irq safe") for a different reason.
Therefore revert commit a841796f11c9 ("signal: align >
__lock_task_sighand() irq disabling and RCU") as the interrupt disable
dance is not longer required.
The change was tested on the base of b4abf91047cf ("rtmutex: Make wait_lock
irq safe") with a four hour run of rcutorture scenario TREE03 with lockdep
enabled as suggested by Paul McKenney.

Merge proc_cmdline simplifications.
This re-writes the get_mm_cmdline() logic to be rather simpler than it
used to be, and makes the semantics for "cmdline goes past the end of
the original area" more natural.
You _can_ use prctl(PR_SET_MM) to just point your command line somewhere
else entirely, but the traditional model is to just edit things in place
and that still needs to continue to work. At least this way the code
makes some sense.

Pull clk updates from Stephen Boyd:
"This time we have a good set of changes to the core framework that do
some general cleanups, but nothing too major. The majority of the diff
goes to two SoCs, Actions Semi and Qualcomm. A brand new driver is
introduced for Actions Semi so it takes up some lines to add all the
different types, and the Qualcomm diff is there because we add support
for two SoCs and it's quite a bit of data.
Otherwise the big driver updates are on TI Davinci and Amlogic
platforms. And then the long tail of driver updates for various fixes
and stuff follows after that.
Core:
- debugfs cleanups removing error checking and an unused provider API
- Removal of a clk init typedef that isn't used
- Usage of match_string() to simplify parent string name matching
- OF clk helpers moved to their own file (linux/of_clk.h)
- Make clk warnings more readable across kernel versions
New Drivers:
- Qualcomm SDM845 GCC and Video clk controllers
- Qualcomm MSM8998 GCC
- Actions Semi S900 SoC support
- Nuvoton npcm750 microcontroller clks
- Amlogic axg AO clock controller
Removed Drivers:
- Deprecated Rockchip clk-gate driver
Updates:
- debugfs functions stopped checking return values
- Support for the MSIOF module clocks on Rensas R-Car M3-N
- Support for the new Rensas RZ/G1C and R-Car E3 SoCs
- Qualcomm GDSC, RCG, and PLL updates for clk changes in new SoCs
- Berlin and Amlogic SPDX tagging
- Usage of of_clk_get_parent_count() in more places
- Proper implementation of the CDEV1/2 clocks on Tegra20
- Allwinner H6 PRCM clock support and R40 EMAC support
- Add critical flag to meson8b's fdiv2 as temporary fixup for ethernet
- Round closest support for meson's mpll driver
- Support for meson8b nand clocks and gxbb video decoder clocks
- Mediatek mali clks
- STM32MP1 fixes
- Uniphier LD11/LD20 stream demux system clock"

Pull staging/IIO updates from Greg KH:
"Here is the big staging and IIO driver update for 4.18-rc1.
It was delayed as I wanted to make sure the final driver deletions did
not cause any major merge issues, and all now looks good.
There are a lot of patches here, just over 1000. The diffstat summary
shows the major changes here:
1007 files changed, 16828 insertions(+), 227770 deletions(-)
Because of this, we might be close to shrinking the overall kernel
source code size for two releases in a row.
There was loads of work in this release cycle, primarily:
- tons of ks7010 driver cleanups
- lots of mt7621 driver fixes and cleanups
- most driver cleanups
- wilc1000 fixes and cleanups
- lots and lots of IIO driver cleanups and new additions
- debugfs cleanups for all staging drivers
- lots of other staging driver cleanups and fixes, the shortlog has
the full details.
but the big user-visable things here are the removal of 3 chunks of
code:
- ncpfs and ipx were removed on schedule, no one has cared about this
code since it moved to staging last year, and if it needs to come
back, it can be reverted.
- lustre file system is removed.
I've ranted at the lustre developers about once a year for the past
5 years, with no real forward progress at all to clean things up
and get the code into the "real" part of the kernel.
Given that the lustre developers continue to work on an external
tree and try to port those changes to the in-kernel tree every once
in a while, this whole thing really really is not working out at
all. So I'm deleting it so that the developers can spend the time
working in their out-of-tree location and get things cleaned up
properly to get merged into the tree correctly at a later date.
Because of these file removals, you will have merge issues on some of
these files (2 in the ipx code, 1 in the ncpfs code, and 1 in the
atomisp driver). Just delete those files, it's a simple merge :)
All of this has been in linux-next for a while with no reported
problems"
