Pull SELinux updates from Paul Moore:
"Seven SELinux patches for v4.15, although five of the seven are small
build fixes and cleanups.
Of the remaining two patches, the only one worth really calling out is
Eric's fix for the SELinux filesystem xattr set/remove code; the other
patch simply converts the SELinux hash table implementation to use
kmem_cache.
Eric's setxattr/removexattr tweak converts SELinux back to calling the
commoncap implementations when the xattr is not SELinux related. The
immediate win is to fixup filesystem capabilities in user namespaces,
but it makes things a bit saner overall; more information in the
commit description"

Pull audit updates from Paul Moore:
"Another relatively small pull request for audit, nine patches total.
The only real new bit of functionality is the patch from Richard which
adds the ability to filter records based on the filesystem type.
The remainder are bug fixes and cleanups; the bug fix highlights
include:
- ensuring that we properly audit init/PID-1 (me)
- allowing the audit daemon to shutdown the kernel/auditd connection
cleanly by setting the audit PID to zero (Steve)"
* tag 'audit-pr-20171113' of git://git.kernel.org/pub/scm/linux/kernel/git/pcmoore/audit:
audit: filter PATH records keyed on filesystem magic
Audit: remove unused audit_log_secctx function
audit: Allow auditd to set pid to 0 to end auditing
audit: Add new syscalls to the perm=w filter
audit: use audit_set_enabled() in audit_enable()
audit: convert audit_ever_enabled to a boolean
audit: don't use simple_strtol() anymore
audit: initialize the audit subsystem as early as possible
audit: ensure that 'audit=1' actually enables audit for PID 1
This matters at least for the mincore syscall, which will otherwise copy
uninitialized memory from the page allocator to userspace. It is
probably also a correctness error for /proc/$pid/pagemap, but I haven't
tested that.
Removing the `walk->hugetlb_entry` condition in walk_hugetlb_range() has
no effect because the caller already checks for that.
This only reports holes in hugetlb ranges to callers who have specified
a hugetlb_entry callback.
This issue was found using an AFL-based fuzzer.
v2:
- don't crash on ->pte_hole==NULL (Andrew Morton)
- add Cc stable (Andrew Morton)

Pull arm64 updates from Will Deacon:
"The big highlight is support for the Scalable Vector Extension (SVE)
which required extensive ABI work to ensure we don't break existing
applications by blowing away their signal stack with the rather large
new vector context (<= 2 kbit per vector register). There's further
work to be done optimising things like exception return, but the ABI
is solid now.
Much of the line count comes from some new PMU drivers we have, but
they're pretty self-contained and I suspect we'll have more of them in
future.

This tag contains the core RISC-V Linux port, which has been through
nine rounds of review on various mailing lists. The port is not
complete: there's some cleanup patches moving through the review
process, a whole bunch of drivers that need some work, and a lot of
feature additions that will be needed.
The patches contained in this tag have been through nine rounds of
review on the various mailing lists. I have some outstanding cleanup
patches, but since there's been so much review on these patches I
thought it would be best to submit them as-is and then submit explicit
cleanup patches so everyone can review them. This first patch set is
big enough that it's a bit of a pain to constantly rewrite, and it's
caused a few headaches with various contributors.
The port is definately a work in progress. While what's there builds
and boots with 4.14, it's a bit hard to actually see anything happen
because there are no device drivers yet. I maintain a staging branch
that contains all the device drivers and cleanup that actually works,
but those patches won't all be ready for a while. I'd like to get what
we currently have into your tree so everyone can start working from a
single base -- of particular importance is allowing the glibc
upstreaming process to proceed so we can sort out any possibly lingering
user-visible ABI problems we might have.
Copied below is the ChangeLog that contains the history of this patch
set:
(v9) As per suggestions on our v8 patch set, I've split the core architecture code
out from our drivers and would like to submit this patch set to be included
into linux-next, with the goal being to be merged in during the next merge
window. This patch set is based on 4.14-rc2, but if it's better to have it
based on something else then I can change it around.
This patch set contains just the core arch code for RISC-V, so while it builds
an nominally boots, you can't print or take an interrupt so it's not that
useful. If you're looking to actually boot a system it would probably be
better to use the full patch set listed below.
We've collected a handful of tags from reviewers, and the remainder of the
patch set only got minimal feedback last time. Here's what changed:
* We now use the device tree to initialize the timer driver so it's less
tighly coupled with the arch port.
* I cleaned up the defconfigs -- there's actually now just one, and it's
empty. For now I think we're OK with what the kernel sets as defaults, but
I anticipate we'll begin to expand this as people start to use the port
more.
* The VDSO symbols version is sane.
* We WFI while spinning in the boot loop.
* A handful of comments have been added.
While there are still a handful of FIXMEs in this patch set, we've started to
get enough interest from various users and contributors that maintaining an out
of tree patch set is starting to become a big burden. Hopefully the patches
are good enough to merge now, which will at least get everyone working in a
more reasonable manner as we clean up the remaining issues.
This patch set is also availiable on github
https://github.com/riscv/riscv-linux/tree/riscv-for-submission-v9-arch
as is the entire patch set necessary to get a more functional RISC-V system up
and running, including a handful of patches that aren't ready for upstream yet.
https://github.com/riscv/riscv-linux/tree/riscv-for-submission-v9
Hopefully I've managed to get everyone's feedback
Here's the change highlights from the whole patch set:
(v8) I know it may not be the ideal time to submit a patch set right now, as
it's the middle of the merge window, but things have calmed down quite a bit in
the last month so I thought it would be good to get everyone on the same page.
There's been a handful of changes since the last patch set, but most of them
are fairly minor:
* We changed PAGE_OFFSET to allowing mapping more physical memory on 64-bit
systems. This is user configurable, as it triggers a different code model
that generates slightly less efficient code.
* The device tree binding documentation is back, I'd managed to lose it at some
point.
* We now pass the atomic64 test suite. The SBI timer driver has been
* refactored.
(v7) It's been a while since my last patch set, but the changes han been fairly
minimal:
* The PCI cleanup patches have been dropped, we'll do them as a separate patch
set later.
* We've the Kconfig entries from CONFIG_ISA_* to CONFIG_RISCV_ISA_*, to make
grep easier.
* There have been a handful of memory model related tweaks in I/O land,
particularly relating the PCI and the upcoming platform specification.
There are significant comments in the relevant files. This is still a WIP,
but I think we're close to getting as good as we're going to get until we
end up with some more specifications.
(v6) As it's been only a day since the v5 patch set, the changes are pretty
minimal:
* The patch set is now based on linux-next/master, which I believe is a better
base now that we're getting closer to upstream.
* EARLY_PRINTK is no longer an option. Since the SBI console is reasonable,
there's no penalty to enabling it (and thus no benefit to disabling it).
* The mmap syscalls were refactored a bit.
(v5) Things have really started to calm down, so this is fairly similar to the
v4 patch set. The most interesting changes include:
* We've moved back to a single patch set.
* SMP support has been fixed, I was accidentally running on a non-SMP
configuration. There were various mistakes all over the tree as a result of
this.
* The cmpxchg syscalls have been removed, as they were deemed a bad idea. As
a result, RISC-V Linux systems mandate the A extension. The corresponding
Kconfig entry to enable builds on non-A systems has been removed.
* A few more atomic fixes: mostly fence changes, but those resulted in a
handful of additional macros that were no longer necessary.
* riscv_early_sie has been removed.
(v4) There have only been a few changes since the v3 patch set:
* The cmpxchg64 syscall is no longer enabled on 32-bit systems. It's not
possible to provide this on SMP systems, and it's not necessary as glibc
knows not to call it.
* We provide a ELF_HWCAP so users can determine the ISA of the machine the
kernel is running on.
* The multi-line comments are in a better form.
* There were a handful of headers that could be replaced with the asm-generic
versions, and a few unnecessary definitions.
* We no longer use printk, but instead use pr_*.
* A few Kconfig and defconfig entries have been cleaned up.
(v3) A highlight of the changes since the v2 patch set includes:
* We've split out all our drivers into separate patch sets, which I've already
sent out to the relevant maintainers. I haven't included those patches in
this patch set, but some of them are necessary to build our port. A git
tree that contains all our patch sets merged together lives at
<https://github.com/riscv/riscv-linux/tree/riscv-for-submission-v3>.
* The patch set is now split up differently: rather than being split per
directory it is split per topic. Hopefully this will make it easier to
review the port on the mailing list. The split is a bit rough, so you
probably still want to look at the patch set as a whole.
* atomic.h has been completely rewritten and is hopefully now correct. I've
attempted to sanitize the various other memory model related code as well,
and I think it should all be sane now aside from a handful of FIXMEs
commented in the code.
* We've changed the cmpexchg syscall to always exist and to not be
multiplexed. There is also a VDSO entry for compare and exchange, which
allows kernels with the A extension to execute user code without the A
extension reasonably fast.
* Our user-visible register state now contains enough space for the Q
extension for 128-bit floating point, as well as a few words to allow
extensibility to future ISA extensions like the eventual V extension for
vectors.
* A handful of driver cleanups, but these have been split into separate patch
sets now so I won't duplicate them here.
(v2) A highlight of the changes since the v1 patch set includes:
* We've split out our drivers into the right places, which means now there's
a lot more patches. I'll be submitting these patches to various subsystem
maintainers and including them in any future RISC-V patch sets until
they've been merged.
* The SBI console driver has been completely rewritten to use the HVC helpers
and is now significantly smaller.
* We've begun to use weaker barriers as opposed to just the big "fence".
There's still some work to do here, specifically:
- We need fences in the relaxed MMIO functions.
- The non-relaxed MMIO functions are missing R/W bits on their fences.
- Many AMOs need the aq and rl bits set.
* We now have thread_info in task_struct. As a result, sscratch now contains
TP instead of SP. This was necessary because thread_info is no longer on
the stack.
* A few shared routines have been added that we use instead of creating
another arch copy.

Shadow variables allow callers to associate new shadow fields to existing data
structures. This is intended to be used by livepatch modules seeking to
emulate additions to data structure definitions.
It seems that the intention of the code is to null check the value
returned by function genlmsg_put. But the current code is null
checking the address of the pointer that holds the value returned
by genlmsg_put.
Fix this by properly null checking the value returned by function
genlmsg_put in order to avoid a pontential null pointer dereference.

so we better use rcu_read_lock() till someone
really needs the mutex (if that happens).

With commits 35e015e1f5 and a2d3f3e338, the global 'accept_dad' flag
is also taken into account (default value is 1). If either global or
per-interface flag is non-zero, DAD will be enabled on a given interface.
This is not backward compatible: before those patches, the user could
disable DAD just by setting the per-interface flag to 0. Now, the
user instead needs to set both flags to 0 to actually disable DAD.
Restore the previous behaviour by setting the default for the global
'accept_dad' flag to 0. This way, DAD is still enabled by default,
as per-interface flags are set to 1 on device creation, but setting
them to 0 is enough to disable DAD on a given interface.
- Before 35e015e1f57a7 and a2d3f3e33853:
global per-interface DAD enabled
[default] 1 1 yes
X 0 no
X 1 yes
- After 35e015e1f5 and a2d3f3e33853:
global per-interface DAD enabled
[default] 1 1 yes
0 0 no
0 1 yes
1 0 yes
- After this fix:

Move inclusion of a private kernel header <net/tcp.h>

to fix the following linux/tls.h userspace compilation error:
/usr/include/linux/tls.h:41:21: fatal error: net/tcp.h: No such file or directory
As to this point uapi/linux/tls.h was totaly unusuable for userspace,
cleanup this header file further by moving other redundant includes
to net/tls.h.

iOS devices require the host to be "trusted" before servicing network
packets. Establishing trust requires the user to confirm a dialog on the
iOS device.Until trust is established, the iOS device will silently discard
network packets from the host. Currently, the ipheth driver does not detect
whether an iOS device has established trust with the host, and immediately
sets up the transmit queues.
This causes the following problems:
- Kernel taint due to WARN() in netdev watchdog.
- Dmesg spam ("TX timeout").
- Disruption of user space networking activity (dhcpd, etc...) when new
interface comes up but cannot be used.
- Unnecessary host and device wakeups and USB traffic
Example dmesg output:

[ 1101.320110] ipheth 1-5:4.2: ipheth_tx_timeout: TX timeout
The last message "TX timeout" is repeated every 5 seconds until trust is
established or the device is disconnected, filling up dmesg.
The proposed patch eliminates the problem by, upon connection, keeping the
TX queue and carrier disabled until a packet is first received from the iOS
device. This is reflected by the confirmed_pairing variable in the device
structure. Only after at least one packet has been received from the iOS
device, the transmit queue and carrier are brought up during the periodic
device poll in ipheth_carrier_set. Because the iOS device will always send
a packet immediately upon trust being established, this should not delay
the interface becoming useable. To prevent failed UBRs in
ipheth_rcvbulk_callback from perpetually re-enabling the queue if it was
disabled, a new check is added so only successful transfers re-enable the
queue, whereas failed transfers only trigger an immediate poll.
This has the added benefit of removing the periodic control requests to the
iOS device until trust has been established and thus should reduce wakeup
events on both the host and the iOS device.

We always poll tx for socket, this is sub optimal since this will
slightly increase the waitqueue traversing time and more important,
vhost could not benefit from commit 9e641bdcfa ("net-tun:
restructure tun_do_read for better sleep/wakeup efficiency") even if
we've stopped rx polling during handle_rx(), tx poll were still left
in the waitqueue.

There are no big surprising changes in this cycle, yet not too
boring, either. The biggest change from diffstat POV is the removal
of the legacy OSS driver codes that have been already disabled for a
long time. This will bring a few trivial merge conflicts.
As new features in ASoC side, there are two things: a new AC97 bus
implementation and AMD Stony platform support. Both include the
relevant changes shared with other subsystems, e.g. AC97 MFD changes
and DRM AMD changes.
Some other highlighted topics are:
- A bunch of USB-audio drivers got the hardening against the malicious
device accesses with a new helper code for endpoint sanity check.
- Lots of cleanups for ASoC Intel platform code, including support for
their open source audio firmware.
- Continued ASoC core componentization works.
- Support for scaling MCLK with sample rate in ASoC simple-card.
- Stabler PCM hot-unplug capability, especially for ASoC usages.

Pull i2c updates from Wolfram Sang:
"This contains two bigger than usual tree-wide changes this time. They
all have proper acks, caused no merge conflicts in linux-next where
they have been for a while. They are namely:
- to-gpiod conversion of the i2c-gpio driver and its users (touching
arch/* and drivers/mfd/*)
- adding a sbs-manager based on I2C core updates to SMBus alerts
(touching drivers/power/*)
Other notable changes:
- i2c_boardinfo can now carry a dev_name to be used when the device
is created. This is because some devices in ACPI world need fixed
names to find the regulators.
- the designware driver got a long discussed overhaul of its PM
handling. img-scb and davinci got PM support, too.
- at24 driver has way better OF support. And it has a new maintainer.
Thanks Bartosz for stepping up!
The rest is regular driver updates and fixes"

CORE:
- Fix the semantics of raw GPIO to actually be raw. No
inversion semantics as before, but also no open draining,
and allow the raw operations to affect lines used for
interrupts as the caller supposedly knows what they are
doing if they are getting the big hammer.
- Rewrote the __inner_function() notation calls to names that
make more sense. I just find this kind of code disturbing.
- Drop the .irq_base() field from the gpiochip since now all
IRQs are mapped dynamically. This is nice.
- Support for .get_multiple() in the core driver API. This
allows us to read several GPIO lines with a single
register read. This has high value for some usecases: it
can be used to create oscilloscopes and signal analyzers
and other things that rely on reading several lines at
exactly the same instant. Also a generally nice
optimization. This uses the new assign_bit() macro from
the bitops lib that was ACKed by Andrew Morton and
is implemented for two drivers, one of them being the
generic MMIO driver so everyone using that will be able
to benefit from this.
- Do not allow requests of Open Drain and Open Source
setting of a GPIO line simultaneously. If the hardware
actually supports enabling both at the same time the
electrical result would be disastrous.
- A new interrupt chip core helper. This will be helpful
to deal with "banked" GPIOs, which means GPIO controllers
with several logical blocks of GPIO inside them. This
is several gpiochips per device in the device model, in
contrast to the case when there is a 1-to-1 relationship
between a device and a gpiochip.
NEW DRIVERS:
- Maxim MAX3191x industrial serializer, a very interesting
piece of professional I/O hardware.
- Uniphier GPIO driver. This is the GPIO block from the
recent Socionext (ex Fujitsu and Panasonic) platform.
- Tegra 186 driver. This is based on the new banked GPIO
infrastructure.
OTHER IMPROVEMENTS:
- Some documentation improvements.
- Wakeup support for the DesignWare DWAPB GPIO controller.
- Reset line support on the DesignWare DWAPB GPIO controller.
- Several non-critical bug fixes and improvements for the
Broadcom BRCMSTB driver.
- Misc non-critical bug fixes like exotic errorpaths, removal
of dead code etc.
- Explicit comments on fall-through switch() statements.
