The function calls with octal permissions commonly span multiple lines.
The current test is line oriented and fails to find some matches.
Make the test use the $stat variable instead of the $line variable to span
multiple lines.
Also add a few functions to the known functions with permissions list.
Move the SYMBOLIC_PERMS test to a separate section to find all the S_<FOO>
permissions in any form not just those that have specific function names.
This can now find and fix permissions uses like:
.mode = S_<FOO> | S_<BAR>;

It is possible for a multiple line macro definition to have a false positive
report when an argument is used on a line after a continuation \.
This line might have a leading '+' as the initial character that could be
confused by checkpatch as an operator.
Avoid the leading character on multiple line macro definitions.

S_<FOO> uses should be avoided where octal is more intelligible.
Linus didst say:
: It's *much* easier to parse and understand the octal numbers, while the
: symbolic macro names are just random line noise and hard as hell to
: understand. You really have to think about it.
:
: So we should rather go the other way: convert existing bad symbolic
: permission bit macro use to just use the octal numbers.
:
: The symbolic names are good for the *other* bits (ie sticky bit, and the
: inode mode _type_ numbers etc), but for the permission bits, the symbolic
: names are just insane crap. Nobody sane should ever use them. Not in the
: kernel, not in user space.

Today there are platforms with many CPUs (up to 4K). Trying to boot only
part of the CPUs may result in too long string.
For example lets take NPS platform that is part of arch/arc. This
platform have SMP system with 256 cores each with 16 HW threads (SMT
machine) where HW thread appears as CPU to the kernel. In this example
there is total of 4K CPUs. When one tries to boot only part of the HW
threads from each core the string representing the map may be long... For
example if for sake of performance we decided to boot only first half of
HW threads of each core the map will look like:
0-7,16-23,32-39,...,4080-4087
This patch introduce new syntax to accommodate with such use case. I
added an optional postfix to a range of CPUs which will choose according
to given modulo the desired range of reminders i.e.:
<cpus range>:sed_size/group_size
For example, above map can be described in new syntax like this:
0-4095:8/16
Note that this patch is backward compatible with current syntax.

Make isdigit into a simple range checking inline function:
return '0' <= c && c <= '9';
This code is 1 branch, not 2 because any reasonable compiler can
optimize this code into SUB+CMP, so the code
while (isdigit((c = *s++)))
...
remains 1 branch per iteration HOWEVER it suddenly doesn't do table
lookup priming cacheline nobody cares about.

The strncpy_from_user() accessor is effectively a copy_from_user()
specialised to copy strings, terminating early at a NUL byte if possible.
In other respects it is identical, and can be used to copy an arbitrarily
large buffer from userspace into the kernel. Conceptually, it exposes a
similar attack surface.
As with copy_from_user(), we check the destination range when the kernel
is built with KASAN, but unlike copy_from_user() we do not check the
destination buffer when using HARDENED_USERCOPY. As strncpy_from_user()
calls get_user() in a loop, we must call check_object_size() explicitly.
This patch adds this instrumentation to strncpy_from_user(), per the same
rationale as with the regular copy_from_user(). In the absence of
hardened usercopy this will have no impact as the instrumentation expands
to an empty static inline function.

There are four cases I can see where we could end up with a NULL 'slot' in
radix_tree_next_slot(). This unit test exercises all four of them, making
sure that if in the future we have an unsafe path through
radix_tree_next_slot(), we'll catch it.
Here are details on the four cases:
1) radix_tree_iter_retry() via a non-tagged iteration like
radix_tree_for_each_slot(). In this case we currently aren't seeing a bug
because radix_tree_iter_retry() sets
iter->next_index = iter->index;
which means that in in the else case in radix_tree_next_slot(), 'count' is
zero, so we skip over the while() loop and effectively just return NULL
without ever dereferencing 'slot'.
2) radix_tree_iter_retry() via tagged iteration like
radix_tree_for_each_tagged(). This case was giving us NULL pointer
dereferences in testing, and was fixed with this commit:
commit 3cb9185c6730 ("radix-tree: fix radix_tree_iter_retry() for tagged
iterators.")
This fix doesn't explicitly check for 'slot' being NULL, though, it works
around the NULL pointer dereference by instead zeroing iter->tags in
radix_tree_iter_retry(), which makes us bail out of the if() case in
radix_tree_next_slot() before we dereference 'slot'.
3) radix_tree_iter_next() via via a non-tagged iteration like
radix_tree_for_each_slot(). This currently happens in shmem_tag_pins()
and shmem_partial_swap_usage().
As with non-tagged iteration, 'count' in the else case of
radix_tree_next_slot() is zero, so we skip over the while() loop and
effectively just return NULL without ever dereferencing 'slot'.
4) radix_tree_iter_next() via tagged iteration like
radix_tree_for_each_tagged(). This happens in shmem_wait_for_pins().
radix_tree_iter_next() zeros out iter->tags, so we end up exiting
radix_tree_next_slot() here:
if (flags & RADIX_TREE_ITER_TAGGED) {
void *canon = slot;
iter->tags >>= 1;
if (unlikely(!iter->tags))
return NULL;

There are four cases I can see where we could end up with a NULL 'slot' in
radix_tree_next_slot(). Yet radix_tree_next_slot() never actually checks
whether 'slot' is NULL. It just happens that for the cases where 'slot'
is NULL, some other combination of factors prevents us from dereferencing
it.
It would be very easy for someone to unwittingly change one of these
factors without realizing that we are implicitly depending on it to save
us from a NULL pointer dereference.
Add a comment documenting the things that allow 'slot' to be safely passed
as NULL to radix_tree_next_slot().
Here are details on the four cases:

radix_tree_for_each_slot(). In this case we currently aren't seeing a bug

The select(2) syscall performs a kmalloc(size, GFP_KERNEL) where size grows
with the number of fds passed. We had a customer report page allocation
failures of order-4 for this allocation. This is a costly order, so it might
easily fail, as the VM expects such allocation to have a lower-order fallback.
Such trivial fallback is vmalloc(), as the memory doesn't have to be physically
contiguous and the allocation is temporary for the duration of the syscall
only. There were some concerns, whether this would have negative impact on the
system by exposing vmalloc() to userspace. Although an excessive use of vmalloc
can cause some system wide performance issues - TLB flushes etc. - a large
order allocation is not for free either and an excessive reclaim/compaction can
have a similar effect. Also note that the size is effectively limited by
RLIMIT_NOFILE which defaults to 1024 on the systems I checked. That means the
bitmaps will fit well within single page and thus the vmalloc() fallback could
be only excercised for processes where root allows a higher limit.
Note that the poll(2) syscall seems to use a linked list of order-0 pages, so
it doesn't need this kind of fallback.

After much discussion, it seems that the fallocate feature flag
FALLOC_FL_ZERO_RANGE maps nicely to SCSI WRITE SAME; and the feature
FALLOC_FL_PUNCH_HOLE maps nicely to the devices that have been whitelisted
for zeroing SCSI UNMAP. Punch still requires that FALLOC_FL_KEEP_SIZE is
set. A length that goes past the end of the device will be clamped to the
device size if KEEP_SIZE is set; or will return -EINVAL if not. Both
start and length must be aligned to the device's logical block size.
Since the semantics of fallocate are fairly well established already, wire
up the two pieces. The other fallocate variants (collapse range, insert
range, and allocate blocks) are not supported.

Make sure that the offset and length arguments that we're using to
construct WRITE SAME and DISCARD requests are actually aligned to the
logical block size. Failure to do this causes other errors in other parts
of the block layer or the SCSI layer because disks don't support partial
logical block writes.

Patch series "fallocate for block devices", v11.
This is a patchset to fix page cache coherency with BLKZEROOUT and
implement fallocate for block devices.
The first patch is a fix to the existing BLKZEROOUT ioctl to invalidate
the page cache if the zeroing command to the underlying device succeeds.
Without this patch we still have the pagecache coherence bug that's been
in the kernel forever.
The second patch changes the internal block device functions to reject
attempts to discard or zeroout that are not aligned to the logical block
size. Previously, we only checked that the start/len parameters were
512-byte aligned, which caused kernel BUG_ONs for unaligned IOs to 4k-LBA
devices.
The third patch creates an fallocate handler for block devices, wires up
the FALLOC_FL_PUNCH_HOLE flag to zeroing-discard, and connects
FALLOC_FL_ZERO_RANGE to write-same so that we can have a consistent
fallocate interface between files and block devices. It also allows the
combination of PUNCH_HOLE and NO_HIDE_STALE to invoke non-zeroing discard.
Test cases for the new block device fallocate are now in xfstests as
generic/349-351.
This patch (of 3):
Invalidate the page cache (as a regular O_DIRECT write would do) to avoid
returning stale cache contents at a later time.

Pull IOMMU updates from Joerg Roedel:
- support for interrupt virtualization in the AMD IOMMU driver. These
patches were shared with the KVM tree and are already merged through
that tree.
- generic DT-binding support for the ARM-SMMU driver. With this the
driver now makes use of the generic DMA-API code. This also required
some changes outside of the IOMMU code, but these are acked by the
respective maintainers.
- more cleanups and fixes all over the place.

git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm
Pull libnvdimm updates from Dan Williams:
"Aside from the recently added pmem sub-division support these have
been in -next for several releases with no reported issues. The sub-
division support was included in next-20161010 with no reported
issues. It passes all unit tests including new tests for all the new
functionality below.
Summary:
- PMEM sub-division support: Allow a single PMEM region to be divided
into multiple namespaces. Originally, ~2 years ago, it was thought
that partitions of a /dev/pmemX block device could handle
sub-allocations of persistent memory for different use cases. With
the decision to not support DAX mappings of raw block-devices, and
the genesis of device-dax, the need for having multiple
pmem-namespace per region has grown.
- Device-DAX unified inode: In support of dynamic-resizing of a
device-dax instance the kernel arranges for all mappings of a
device-dax node to share the same inode. This allows unmap /
truncate / invalidation events to affect all instances of the
device similar to the behavior of mmap on block devices.
- Hardware error scrubbing reworks: The original address-range-scrub
and badblocks tracking solution allowed clearing entries at the
individual namespace level, but it failed to clear the internal
list of media errors maintained at the bus level. The result was
that the next scrub or namespace disable/re-enable event would
restore the cleared badblocks, but now that is fixed. The v4.8
kernel introduced an auto-scrub-on-machine-check behavior to
repopulate the badblocks list. Now, in v4.9, the auto-scrub
behavior can be disabled and simply arrange for the error reported
in the machine-check to be added to the list.
- DIMM health-event notification support: ACPI 6.1 defines a
notification event code that can be send to ACPI NVDIMM devices. A
poll(2) capable file descriptor for these events can be obtained
from the nmemX/nfit/flags sysfs-attribute of a libnvdimm memory
device.
- Miscellaneous fixes: NVDIMM-N probe error, device-dax build error,
and a change to dedup the flush hint list to not flush the memory
controller more than necessary"
