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"

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.

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.
Plenty of acronym soup here:
- initial support for the Scalable Vector Extension (SVE)
- improved handling for SError interrupts (required to handle RAS
events)
- enable GCC support for 128-bit integer types
- remove kernel text addresses from backtraces and register dumps
- use of WFE to implement long delay()s
- ACPI IORT updates from Lorenzo Pieralisi
- perf PMU driver for the Statistical Profiling Extension (SPE)
- perf PMU driver for Hisilicon's system PMUs

Pull RISC-V architecture support from Palmer Dabbelt:
"This 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.
(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.
- 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"

After commit 890da9cf0983 (Revert "x86: do not use cpufreq_quick_get()
for /proc/cpuinfo "cpu MHz"") the "cpu MHz" number in /proc/cpuinfo
on x86 can be either the nominal CPU frequency (which is constant)
or the frequency most recently requested by a scaling governor in
cpufreq, depending on the cpufreq configuration. That is somewhat
inconsistent and is different from what it was before 4.13, so in
order to restore the previous behavior, make it report the current
CPU frequency like the scaling_cur_freq sysfs file in cpufreq.
To that end, modify the /proc/cpuinfo implementation on x86 to use
aperfmperf_snapshot_khz() to snapshot the APERF and MPERF feedback
registers, if available, and use their values to compute the CPU
frequency to be reported as "cpu MHz".
However, do that carefully enough to avoid accumulating delays that
lead to unacceptable access times for /proc/cpuinfo on systems with
many CPUs. Run aperfmperf_snapshot_khz() once on all CPUs
asynchronously at the /proc/cpuinfo open time, add a single delay
upfront (if necessary) at that point and simply compute the current
frequency while running show_cpuinfo() for each individual CPU.
Also, to avoid slowing down /proc/cpuinfo accesses too much, reduce
the default delay between consecutive APERF and MPERF reads to 10 ms,
which should be sufficient to get large enough numbers for the
frequency computation in all cases.

DW ethernet controller on axs10x hangs sometimes after SW reset.
Invoke the newly aded driver (reset-axs10x.c) by adding the DT bits.
With this in place, we don't need the open-coded quirk in platform
code, so get rid of it as well !

The 'struct key_preparsed_payload' will use 'time_t' which we will
try to remove in the kernel, since 'time_t' is not year 2038 safe on
32bits systems.
Thus this patch replaces 'time_t' with 'time64_t' which is year 2038
safe on 32 bits system for 'struct key_preparsed_payload', moreover
we should use the 'TIME64_MAX' macro to initialize the 'time64_t'
type variable.

The 'struct key' will use 'time_t' which we try to remove in the
kernel, since 'time_t' is not year 2038 safe on 32bit systems.
Also the 'struct keyring_search_context' will use 'timespec' type
to record current time, which is also not year 2038 safe on 32bit
systems.
Thus this patch replaces 'time_t' with 'time64_t' which is year 2038
safe for 'struct key', and replace 'timespec' with 'time64_t' for the
'struct keyring_search_context', since we only look at the the seconds
part of 'timespec' variable. Moreover we also change the codes where
using the 'time_t' and 'timespec', and we can get current time by
ktime_get_real_seconds() instead of current_kernel_time(), and use
'TIME64_MAX' macro to initialize the 'time64_t' type variable.
Especially in proc.c file, we have replaced 'unsigned long' and 'timespec'
type with 'u64' and 'time64_t' type to save the timeout value, which means
user will get one 'u64' type timeout value by issuing proc_keys_show()
function.

When keyctl_read() is passed a buffer that is too small, the behavior is
inconsistent. Some key types will fill as much of the buffer as
possible, while others won't copy anything. Moreover, the in-kernel
documentation contradicted the man page on this point.
Update the in-kernel documentation to say that this point is
unspecified.

Newer firmware versions (such as iwlwifi-8000C-34.ucode) have
introduced an API change in the SCAN_REQ_UMAC command that is not
backwards compatible. The driver needs to detect and use the new API
format when the firmware reports it, otherwise the scan command will
not work properly, causing a command timeout.
Fix this by adding a TLV that tells the driver that the new API is in
use and use the correct structures for it.
This fixes https://bugzilla.kernel.org/show_bug.cgi?id=197591

The patch from commit a7e3b975a0f9 ("Btrfs: fix reported number of inode
blocks") introduced a regression where if we do a buffered write starting
at position equal to or greater than the file's size and then stat(2) the
file before writeback is triggered, the number of used blocks does not
change (unless there's a prealloc/unwritten extent). Example:
$ xfs_io -f -c "pwrite -S 0xab 0 64K" foobar
$ du -h foobar
0 foobar
$ sync
$ du -h foobar
64K foobar
The first version of that patch didn't had this regression and the second
version, which was the one committed, was made only to address some
performance regression detected by the intel test robots using fs_mark.
This fixes the regression by setting the new delaloc bit in the range, and
doing it at btrfs_dirty_pages() while setting the regular dealloc bit as
well, so that this way we set both bits at once avoiding navigation of the
inode's io tree twice. Doing it at btrfs_dirty_pages() is also the most
meaninful place, as we should set the new dellaloc bit when if we set the
delalloc bit, which happens only if we copied bytes into the pages at
__btrfs_buffered_write().
This was making some of LTP's du tests fail, which can be quickly run
using a command line like the following:
$ ./runltp -q -p -l /ltp.log -f commands -s du -d /mnt

Move the definition of the function btrfs_find_new_delalloc_bytes() closer
to the function btrfs_dirty_pages(), because in a future commit it will be

This is a test utility to verify ION buffer sharing in user space
between 2 independent processes.
It uses unix domain socket (with SCM_RIGHTS) as IPC to transfer an FD to
another process to share the same buffer.
This utility demonstrates how ION buffer sharing can be implemented between
two user space processes, using various heap types.
This utility is made to be run as part of kselftest framework in kernel.
The utility is verified on Ubuntu-32 bit system with Linux Kernel 4.14,
using ION system heap.
For more information about the utility please check the README file.

When creating a pathname close to PATH_MAX to test execveat, factor in
the current working directory path otherwise we end up with an absolute
path that is longer than PATH_MAX. While execveat() may succeed, subsequent
calls to the kernel from the runtime environment which are required to
successfully execute the test binary/script may fail because of this.
To keep the semantics of the test the same, rework the relative pathname
part of the test to be relative to the root directory so it isn't
decreased by the length of the current working directory path.

Apparently some sinks look at the YQ bits even when receiving RGB,
and they get somehow confused when they see a non-zero YQ value.
So we can't just blindly follow CEA-861-F and set YQ to match the
RGB range.
Unfortunately there is no good way to tell whether the sink
designer claims to have read CEA-861-F. The CEA extension block
revision number has generally been stuck at 3 since forever,
and even a very recently manufactured sink might be based on
an old design so the manufacturing date doesn't seem like
something we can use. In lieu of better information let's
follow CEA-861-F only for HDMI 2.0 sinks, since HDMI 2.0 is
based on CEA-861-F. For HDMI 1.x sinks we'll always set YQ=0.
The alternative would of course be to always set YQ=0. And if
we ever encounter a HDMI 2.0+ sink with this bug that's what
we'll probably have to do.

The dev_alloc_list list could be protected by various mutexes,
depending on the context. The list tracks devices that can take part of
allocating new chunks, so the closest mutex is chunk_mutex. Adding a new
device from inside the ADD_DEV ioctl will need device_list_mutex and
registering a new device from the ioctl needs uuid_mutex.
All mutexes naturally guarantee exclusivity against the same context.
The device ownership can move between the contexts and the exclusivity
is guaranteed by other means, eg. during the mount with the uuid_mutex.
There's no RCU involved for dev_alloc_list.

This fixes potential bio leaks, in several error paths. Unfortunatelly
the device structure freeing is opencoded in many places and I missed
them when introducing the flush_bio.
Most of the time, devices get freed through call_rcu(..., free_device),
so it at least it's not that easy to hit the leak, but it's still
possible through the path that frees stale devices.

Compression code path has only flaged bios with REQ_OP_WRITE no matter
where the bios come from, but it could be a sync write if fsync starts
this writeback or a normal writeback write if wb kthread starts a
periodic writeback.
It breaks the rule that sync writes and writeback writes need to be
differentiated from each other, because from the POV of block layer,
all bios need to be recognized by these flags in order to do some
management, e.g. throttlling.
This passes writeback_control to compression write path so that it can
send bios with proper flags to block layer.
