Merge tag 'overflow-v4.18-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/kees/linux
Pull overflow updates from Kees Cook:
"This adds the new overflow checking helpers and adds them to the
2-factor argument allocators. And this adds the saturating size
helpers and does a treewide replacement for the struct_size() usage.
Additionally this adds the overflow testing modules to make sure
everything works.
I'm still working on the treewide replacements for allocators with
"simple" multiplied arguments:
*alloc(a * b, ...) -> *alloc_array(a, b, ...)
and
*zalloc(a * b, ...) -> *calloc(a, b, ...)
as well as the more complex cases, but that's separable from this
portion of the series. I expect to have the rest sent before -rc1
closes; there are a lot of messy cases to clean up.
Summary:
- Introduce arithmetic overflow test helper functions (Rasmus)
- Use overflow helpers in 2-factor allocators (Kees, Rasmus)
- Introduce overflow test module (Rasmus, Kees)
- Introduce saturating size helper functions (Matthew, Kees)
- Treewide use of struct_size() for allocators (Kees)"
* tag 'overflow-v4.18-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/kees/linux:
treewide: Use struct_size() for devm_kmalloc() and friends
treewide: Use struct_size() for vmalloc()-family
treewide: Use struct_size() for kmalloc()-family
device: Use overflow helpers for devm_kmalloc()
mm: Use overflow helpers in kvmalloc()
mm: Use overflow helpers in kmalloc_array*()
test_overflow: Add memory allocation overflow tests
overflow.h: Add allocation size calculation helpers
test_overflow: Report test failures
test_overflow: macrofy some more, do more tests for free
lib: add runtime test of check_*_overflow functions
compiler.h: enable builtin overflow checkers and add fallback code
One of the more common cases of allocation size calculations is finding
the size of a structure that has a zero-sized array at the end, along
with memory for some number of elements for that array. For example:
struct foo {
int stuff;
void *entry[];
};
instance = kmalloc(sizeof(struct foo) + sizeof(void *) * count, GFP_KERNEL);
Instead of leaving these open-coded and prone to type mistakes, we can
now use the new struct_size() helper:
instance = kmalloc(struct_size(instance, entry, count), GFP_KERNEL);
This patch makes the changes for kmalloc()-family (and kvmalloc()-family)
uses. It was done via automatic conversion with manual review for the
"CHECKME" non-standard cases noted below, using the following Coccinelle
script:
// pkey_cache = kmalloc(sizeof *pkey_cache + tprops->pkey_tbl_len *
// sizeof *pkey_cache->table, GFP_KERNEL);

Merge tag 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/rdma/rdma
Pull rdma fixes from Jason Gunthorpe:
"Just three small last minute regressions that were found in the last
week. The Broadcom fix is a bit big for rc7, but since it is fixing
driver crash regressions that were merged via netdev into rc1, I am
sending it.
- bnxt netdev changes merged this cycle caused the bnxt RDMA driver
to crash under certain situations
- Arnd found (several, unfortunately) kconfig problems with the
patches adding INFINIBAND_ADDR_TRANS. Reverting this last part,
will fix it more fully outside -rc.
- Subtle change in error code for a uapi function caused breakage in
userspace. This was bug was subtly introduced cycle"
* tag 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/rdma/rdma:
IB/core: Fix error code for invalid GID entry
IB: Revert "remove redundant INFINIBAND kconfig dependencies"
RDMA/bnxt_re: Fix broken RoCE driver due to recent L2 driver changes
A follow-up patch enables emitting VLAN notifications for the bridge CPU
port in addition to the existing slave port notifications. These
notifications have orig_dev set to the bridge in question.
Because there's no specific support for these VLANs, just ignore the
notifications to maintain the current behavior.

DMA requests must be blocked before resetting VDE HW, otherwise it is
possible to get a memory corruption or a machine hang. Use the reset
control provided by the Memory Controller to block DMA before resetting
the VDE HW.

Remove dependencies on HAS_DMA where a Kconfig symbol depends on another
symbol that implies HAS_DMA, and, optionally, on "|| COMPILE_TEST".
In most cases this other symbol is an architecture or platform specific
symbol, or PCI.
Generic symbols and drivers without platform dependencies keep their
dependencies on HAS_DMA, to prevent compiling subsystems or drivers that
cannot work anyway.
This simplifies the dependencies, and allows to improve compile-testing.
Note:
- The various VIDEOBUF*DMA* symbols had to loose their dependencies on
HAS_DMA, as they are selected by several individual drivers.

Several subsystems depend on INFINIBAND_ADDR_TRANS, which in turn depends
on INFINIBAND. However, when with CONFIG_INIFIBAND=m, this leads to a
link error when another driver using it is built-in. The
INFINIBAND_ADDR_TRANS dependency is insufficient here as this is
a 'bool' symbol that does not force anything to be a module in turn.

This driver hasn't been tested in a long, long time. The hardware is
ancient and pretty much obsolete. This driver also needs to be converted
to newer media frameworks (vb2!) but due to the lack of time and interest
that is unlikely to happen.
So this driver is a prime candidate for removal. If someone is interested
in working on this driver to prevent its removal, then please contact the
linux-media mailinglist.

The atomisp driver has a long list of todo items and little has been done
to address these lately while more has been added. The driver is also not
functional. In other words, the driver would not be getting out of staging
in the foreseeable future. At the same time it consumes developer
resources in order to maintain the flaky code base. Remove it.

When atomisp got merged, there were so many warnings with W=1
that we simply disabled the ones that were causing troubles.
Since then, several changes got applied to atomisp, and the
number of warnings are a way smaller than it used to be.
So, let's reenable warnings there and fix the issues.

IA_CSS_ERROR shows the ddr_buffer_addr as a decimal value with a '0x'
prefix, which is somewhat misleading.
Let's fix it to print hexadecimal, as was intended.

Just set up the show callback in the tty_operations, and use
proc_create_single_data to create the file without additional
boilerplace code.

Unwind the registration loop into individual calls. Switch to use
proc_create_single where applicable.
Also don't bother handling proc_create* failures - the driver works
perfectly fine without the proc files, and the cleanup will handle
missing files gracefully.

Variants of proc_create{,_data} that directly take a seq_file show
callback and drastically reduces the boilerplate code in the callers.
All trivial callers converted over.

The data protected is video_out2 and the lock that is released is
&video_out2->dma_queue_lock, so it seems that that lock should be
taken as well.

Since commit 50b0f0aee8 ("gpu: ipu-csi: add 10/12-bit grayscale
support to mbus_code_to_bus_cfg") the IPU CSI can be configured to
capture 10-bit and 12-bit grayscale formats, expanded to 16-bit
grayscale, in bayer/generic data mode.
This patch adds support for V4L2_PIX_FMT_Y16 captured from sensors
that provide MEDIA_BUS_FMT_Y10_1X10 or MEDIA_BUS_FMT_Y12_1X12 data.

This is Open Firmware driver, hence 'of_device.h' should be included

Stride of U/V planes must be aligned to 16 bytes (2 macroblocks). This
needs to be taken into account, otherwise it is possible to get a silent
