r8152: fix wrong checksum status for received IPv4 packets
The device could only check the checksum of TCP and UDP packets. Therefore, for the IPv4 packets excluding TCP and UDP, the check of checksum is necessary, even though the IP checksum is correct. Take ICMP for example, The IP checksum may be correct, but the ICMP checksum may be wrong. Signed-off-by: Hayes Wang <hayeswang@realtek.com> Signed-off-by: David S. Miller <davem@davemloft.net> |

nfp: fix TLV offset calculation
The data pointer in the config space TLV parser already includes
NFP_NET_CFG_TLV_BASE, it should not be added again. Incorrect
offset values were only used in printed user output, rendering
the bug merely cosmetic.

x86/power: Fix swsusp_arch_resume prototype
The declaration for swsusp_arch_resume marks it as 'asmlinkage', but the
definition in x86-32 does not, and it fails to include the header with the
declaration. This leads to a warning when building with
link-time-optimizations:
kernel/power/power.h:108:23: error: type of 'swsusp_arch_resume' does not match original declaration [-Werror=lto-type-mismatch]
extern asmlinkage int swsusp_arch_resume(void);
^
arch/x86/power/hibernate_32.c:148:0: note: 'swsusp_arch_resume' was previously declared here
int swsusp_arch_resume(void)
This moves the declaration into a globally visible header file and fixes up
both x86 definitions to match it.

x86/dumpstack: Avoid uninitlized variable
In some configurations, 'partial' does not get initialized, as shown by
this gcc-8 warning:
arch/x86/kernel/dumpstack.c: In function 'show_trace_log_lvl':
arch/x86/kernel/dumpstack.c:156:4: error: 'partial' may be used uninitialized in this function [-Werror=maybe-uninitialized]
show_regs_if_on_stack(&stack_info, regs, partial);
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
This initializes it to false, to get the previous behavior in this case.

This is the bulk of pin control changes for the v4.16 kernel cycle:
Core changes:
- After lengthy discussions and partly due to my ignorance, we have
merged a patch making pinctrl_force_default() and pinctrl_force_sleep()
reprogram the states into the hardware of any hogged pins, even
if they are already in the desired state. This only apply to hogged
pins since groups of pins owned by drivers need to be managed by
each driver, lest they could not do things like runtime PM and
put pins to sleeping state even if the system as a whole is not
in sleep.
New drivers:
- New driver for the Microsemi Ocelot SoC. This is used in ethernet
switches.
- The X-Powers AXP209 GPIO driver was extended to also deal with pin
control and moved over from the GPIO subsystem. This circuit is
a mixed-mode integrated circuit which is part of AllWinner designs.
- New subdriver for the Qualcomm MSM8998 SoC, core of a high end
mobile devices (phones) chipset.
- New subdriver for the ST Microelectronics STM32MP157 MPU and
STM32F769 MCU from the STM32 family.
- New subdriver for the MediaTek MT7622 SoC. This is used for routers,
repeater, gateways and such network infrastructure.
- New subdriver for the NXP (former Freescale) i.MX 6ULL. This SoC has
multimedia features and target "smart devices", I guess in-car
entertainment, in-flight entertainment, industrial control panels etc.
General improvements:
- Incremental improvements on the SH-PFC subdrivers for things like
the CAN bus.
- Enable the glitch filter on Baytrail GPIOs used for interrupts.
- Proper handling of pins to GPIO ranges on the Semtec SX150X
- An IRQ setup ordering fix on MCP23S08.
- A good set of janitorial coding style fixes.

powerpc updates for 4.16
Highlights:
- Enable support for memory protection keys aka "pkeys" on Power7/8/9 when
using the hash table MMU.
- Extend our interrupt soft masking to support masking PMU interrupts as well
as "normal" interrupts, and then use that to implement local_t for a ~4x
speedup vs the current atomics-based implementation.
- A new driver "ocxl" for "Open Coherent Accelerator Processor Interface
(OpenCAPI)" devices.
- Support for new device tree properties on PowerVM to describe hotpluggable
memory and devices.
- Add support for CLOCK_{REALTIME/MONOTONIC}_COARSE to the 64-bit VDSO.
- Freescale updates from Scott:
"Contains fixes for CPM GPIO and an FSL PCI erratum workaround, plus a
minor cleanup patch."
As well as quite a lot of other changes all over the place, and small fixes and
cleanups as always.

block: skd: fix incorrect linux/slab_def.h inclusion
skd includes slab_def.h to get access to the slab cache object size.
However, including this header breaks when we use SLUB or SLOB instead of
the SLAB allocator, since the structure layout is completely different,
as shown by this warning when we build this driver in one of the invalid
configurations with link-time optimizations enabled:
include/linux/slab.h:715:0: error: type of 'kmem_cache_size' does not match original declaration [-Werror=lto-type-mismatch]
unsigned int kmem_cache_size(struct kmem_cache *s);
mm/slab_common.c:77:14: note: 'kmem_cache_size' was previously declared here
unsigned int kmem_cache_size(struct kmem_cache *s)
^
mm/slab_common.c:77:14: note: code may be misoptimized unless -fno-strict-aliasing is used
include/linux/slab.h:147:0: error: type of 'kmem_cache_destroy' does not match original declaration [-Werror=lto-type-mismatch]
void kmem_cache_destroy(struct kmem_cache *);
mm/slab_common.c:858:6: note: 'kmem_cache_destroy' was previously declared here

^
mm/slab_common.c:858:6: note: code may be misoptimized unless -fno-strict-aliasing is used
include/linux/slab.h:140:0: error: type of 'kmem_cache_create' does not match original declaration [-Werror=lto-type-mismatch]
struct kmem_cache *kmem_cache_create(const char *name, size_t size,
mm/slab_common.c:534:1: note: 'kmem_cache_create' was previously declared here
kmem_cache_create(const char *name, size_t size, size_t align,
^
This removes the header inclusion and instead uses the kmem_cache_size()
interface to get the size in a reliable way.

buffer: Avoid setting buffer bits that are already set
It's expensive to set buffer flags that are already set, because that causes a costly cache line transition. A common case is setting the "verified" flag during ext4 writes. This patch checks for the flag being set first. With the AIM7/creat-clo benchmark testing on a 48G ramdisk based-on ext4 file system, we see 3.3%(15431->15936) improvement of aim7.jobs-per-min on a 2-sockets broadwell platform. What the benchmark does is: it forks 3000 processes, and each process do the following: a) open a new file b) close the file c) delete the file until loop=100*1000 times. The original patch is contributed by Andi Kleen.

The core framework has a handful of patches this time around, mostly due
to the clk rate protection support added by Jerome Brunet. This feature
will allow consumers to lock in a certain rate on the output of a clk so
that things like audio playback don't hear pops when the clk frequency
changes due to shared parent clks changing rates. Currently the clk
API doesn't guarantee the rate of a clk stays at the rate you request
after clk_set_rate() is called, so this new API will allow drivers
to express that requirement. Beyond this, the core got some debugfs
pretty printing patches and a couple minor non-critical fixes.
Looking outside of the core framework diff we have some new driver
additions and the removal of a legacy TI clk driver. Both of these hit
high in the dirstat. Also, the removal of the asm-generic/clkdev.h file
causes small one-liners in all the architecture Kbuild files. Overall, the
driver diff seems to be the normal stuff that comes all the time to
fix little problems here and there and to support new hardware.
Core:
- Clk rate protection
- Symbolic clk flags in debugfs output
- Clk registration enabled clks while doing bookkeeping updates
New Drivers:
- Spreadtrum SC9860
- HiSilicon hi3660 stub
- Qualcomm A53 PLL, SPMI clkdiv, and MSM8916 APCS
- Amlogic Meson-AXG
- ASPEED BMC
Removed Drivers:
- TI OMAP 3xxx legacy clk (non-DT) support
- asm*/clkdev.h got removed (not really a driver)
Updates:
- Renesas FDP1-0 module clock on R-Car M3-W
- Renesas LVDS module clock on R-Car V3M
- Misc fixes to pr_err() prints
- Qualcomm MSM8916 audio fixes
- Qualcomm IPQ8074 rounded out support for more peripherals
- Qualcomm Alpha PLL variants
- Divider code was using container_of() on bad pointers
- Allwinner DE2 clks on H3
- Amlogic minor data fixes and dropping of CLK_IGNORE_UNUSED
- Mediatek clk driver compile test support
- AT91 PMC clk suspend/resume restoration support
- PLL issues fixed on si5351
- Broadcom IProc PLL calculation updates
- DVFS support for Armada mvebu CPU clks
- Allwinner fixed post-divider support
- TI clkctrl fixes and support for newer SoCs

ARM: SoC platform updates for 4.16
These are mostly minor bugfixes, cleanup and many defconfig updates to support added drivers. In particular OMAP and PXA keep cleaning up the legacy code base, as usual. Nvidia adds some more SoC support code for Tegra 186. For the first time on years, we are actually adding a non-DT platform for, the EP93xx based Liebherr controller BK3.1. It's a minor variation of the EP93xx reference design and in active use, while EP93xx apparently doesn't have enough new development to have any device tree support. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 iQIcBAABAgAGBQJac0azAAoJEGCrR//JCVInuaAQAJBfJeqhFC01JeO+Oy/Sz3qh WuZpT0ExfU1EFLnyBhEYJujDmlzNPcVacI53gSazpiksHboLpOodW+pX19NwOyzC RSbyLa+W5MH1uXtIzV8dqwXboOWJ/Fh348VTSG4dw2JJ6i4k3U/9xboOVtnynCic ww66FEEpFvJfNgch+7zcpHDwACqJ8nsrortNzEM8eV2jA/DOgv48EemTJqf1Lv1E Z0nqIBEPvInPgCB3MX3KTD6CgbQ1qZOcWcEgR1tDRqmCuCgvp4xawiOBKos6QHaG Iqgi3jI5rPJ391mhIQqK5duU5IKMY0FO6qxir7U+YNZm8vMmijPMwgEmlkG28mTT 6B7+ZNHXnSnFklpMetvCBDB8a+Lximft/oqecumowKJo0R9vZontnP4Jdbt9HLic T99nzw2Xwhxo/J7kQXcGDoLyRAPgS1iiHyWXKbXADRlaftACeXL9iVTg+F9EAveq WTDNmN6hbha4fN5PXUkcTAco96JtevT/H2ZDmYFBCSaqHy3QrNPJtDcVSIJd4CGT uQJwXINHvR/nJrEl2ZLLsfMSJMBXWp79w7xb+QfkIa6UXL3hUwGC9Wd2jQZsdHf3 AQ/Q1oJ6epCvd2+4xo0EwiUMjr2MGqfLmtGBQkMzdSbFe50RhHe3w2Amy3VU03X+ vFB4zAmReWDZXgQ7+Dhg =frm4 -----END PGP SIGNATURE----- Merge tag 'armsoc-soc' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc Pull ARM SoC platform updates from Arnd Bergmann: "These are mostly minor bugfixes, cleanup and many defconfig updates to support added drivers.

It's a minor variation of the EP93xx reference design and in active use, while EP93xx apparently doesn't have enough new development to have any device tree support" * tag 'armsoc-soc' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (73 commits) ARM: omap: hwmod: fix section mismatch warnings ARM: pxa/tosa-bt: add MODULE_LICENSE tag arm64: defconfig: enable CONFIG_ACPI_APEI_EINJ arm64: defconfig: enable EDAC GHES option arm64: defconfig: enable CONFIG_ACPI_APEI_MEMORY_FAILURE ARM: imx_v6_v7_defconfig: enable CONFIG_CPU_FREQ_STAT Wind down ARM/TANGO port ARM: davinci: constify gpio_led ARM: davinci: drop unneeded newline soc: Add SoC driver for Gemini ARM: SAMSUNG: Add SPDX license identifiers ARM: S5PV210: Add SPDX license identifiers ARM: S3C64XX: Add SPDX license identifiers ARM: S3C24XX: Add SPDX license identifiers ARM: EXYNOS: Add SPDX license identifiers ARM: imx: remove unused imx3 pm definitions ARM: imx: don't abort MMDC probe if power saving status doesn't match ARM: imx_v6_v7_defconfig: enable RTC_DRV_MXC_V2 ARM: imx_v6_v7_defconfig: Add missing config for DART-MX6 SoM ARM: davinci: Use PTR_ERR_OR_ZERO() ... |

Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/pmladek/printk
Pull printk updates from Petr Mladek:
- Add a console_msg_format command line option:
The value "default" keeps the old "[time stamp] text\n" format. The
value "syslog" allows to see the syslog-like "<log
level>[timestamp] text" format.
This feature was requested by people doing regression tests, for
example, 0day robot. They want to have both filtered and full logs
at hands.
- Reduce the risk of softlockup:
Pass the console owner in a busy loop.
This is a new approach to the old problem. It was first proposed by
Steven Rostedt on Kernel Summit 2017. It marks a context in which
the console_lock owner calls console drivers and could not sleep.
On the other side, printk() callers could detect this state and use
a busy wait instead of a simple console_trylock(). Finally, the
console_lock owner checks if there is a busy waiter at the end of
the special context and eventually passes the console_lock to the
waiter.
The hand-off works surprisingly well and helps in many situations.
Well, there is still a possibility of the softlockup, for example,
when the flood of messages stops and the last owner still has too
much to flush.
There is increasing number of people having problems with
printk-related softlockups. We might eventually need to get better
solution. Anyway, this looks like a good start and promising
direction.
- Do not allow to schedule in console_unlock() called from printk():
This reverts an older controversial commit. The reschedule helped
to avoid softlockups. But it also slowed down the console output.
This patch is obsoleted by the new console waiter logic described
above. In fact, the reschedule made the hand-off less effective.
- Deprecate "%pf" and "%pF" format specifier:
It was needed on ia64, ppc64 and parisc64 to dereference function
descriptors and show the real function address. It is done
transparently by "%ps" and "pS" format specifier now.
Sergey Senozhatsky found that all the function descriptors were in
a special elf section and could be easily detected.
- Remove printk_symbol() API:
It has been obsoleted by "%pS" format specifier, and this change
helped to remove few continuous lines and a less intuitive old API.
- Remove redundant memsets:
Sergey removed unnecessary memset when processing printk.devkmsg
command line option.

Mostly clean ups and small fixes
There's not much changes for the tracing system this release. Mostly small clean ups and fixes. The biggest change is to how bprintf works. bprintf is used by trace_printk() to just save the format and args of a printf call, and the formatting is done when the trace buffer is read. This is done to keep the formatting out of the fast path (this was recommended by you). The issue is when arguments are de-referenced. If a pointer is saved, and the format has something like "%*pbl", when the buffer is read, it will de-reference the argument then. The problem is if the data no longer exists. This can cause the kernel to oops. The fix for this was to make these de-reference pointes do the formatting at the time it is called (the fast path), as this guarantees that the data exists (and doesn't change later) -----BEGIN PGP SIGNATURE----- iQHIBAABCgAyFiEEPm6V/WuN2kyArTUe1a05Y9njSUkFAlpzUWIUHHJvc3RlZHRA Z29vZG1pcy5vcmcACgkQ1a05Y9njSUk6FQwAqvrOE8AO9cbwB0bxm82aZj7UyYkG D9w4goPiykcNR31wxvM2jhrQn6uqG04g2YFCZntZvZMmGFyu6y/tDxGNGe0cHmVR 1dZkFcst6IAHybY70cIkAcNNJXFFsccTaVcuniidWYwq2K3z2eqK5s3YfA+ZMr0q nfUvv0cIgdGTduM4SuoKr0ewxb779I0tHhQXUnMTeLOWG3HQhOh5LcjdBk/N4pTj axfXIlx8lkHSPOvvUmpJ/R51v7HzfidibEnUrrx46ng3DV81hFdEhwbVl+GO44fP 9Wq7vRCvTThvTZVCg8gaYsuo3+CPISmlkpdq373bCqnKuGynGmXzkFNzXjDHl8pL GPbji/Gu9kSMZaZoBihleaX4G4UW386nqDC2YlLTe4rx6f8phYLxMOC2/8nZ+A3L JKB4PTWKUSSNCfaPgiT6dv/CeaXalcYtgVJ2xM2jFhoOEyM5jwb0f6tdvXsuj5Fn ZlFNTuKWPn0siQIng7EZan3LmIFkukM5sfVF =bmm/ -----END PGP SIGNATURE----- Merge tag 'trace-v4.16' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace Pull tracing updates from Steven Rostedt: "There's not much changes for the tracing system this release.

This turns out to be because we don't check for a data carrying request on the mq scheduler path, and since blk_phys_contig_segment() returns true for a non-data request, we decrement the initial segment count of 0 and end up with 0xffff in the unsigned short. There are a few issues here: 1) We should initialize the segment count for a discard to 1. 2) The discard merging is currently using the data limits for segments and sectors. Fix this up by having attempt_merge() correctly identify the request, and by initializing the segment count correctly for discards. This can only be triggered with mq-deadline on discard capable devices right now, which isn't a common configuration. Signed-off-by: Jens Axboe <axboe@kernel.dk> |

Merge KASAN word-at-a-time fixups from Andrey Ryabinin. The word-at-a-time optimizations have caused headaches for KASAN, since the whole point is that we access byte streams in bigger chunks, and KASAN can be unhappy about the potential extra access at the end of the string. We used to have a horrible hack in dcache, and then people got complaints from the strscpy() case. This fixes it all up properly, by adding an explicit helper for the "access byte stream one word at a time" case. * emailed patches from Andrey Ryabinin <aryabinin@virtuozzo.com>: fs: dcache: Revert "manually unpoison dname after allocation to shut up kasan's reports" fs/dcache: Use read_word_at_a_time() in dentry_string_cmp() lib/strscpy: Shut up KASAN false-positives in strscpy() compiler.h: Add read_word_at_a_time() function. compiler.h, kasan: Avoid duplicating __read_once_size_nocheck() |

fs/dcache: Use read_word_at_a_time() in dentry_string_cmp()
dentry_string_cmp() performs the word-at-a-time reads from 'cs' and may read slightly more than it was requested in kmallac(). Normally this would make KASAN to report out-of-bounds access, but this was workarounded by commit |

lib/strscpy: Shut up KASAN false-positives in strscpy()
strscpy() performs the word-at-a-time optimistic reads. So it may may
access the memory past the end of the object, which is perfectly fine
since strscpy() doesn't use that (past-the-end) data and makes sure the
optimistic read won't cross a page boundary.
Use new read_word_at_a_time() to shut up the KASAN.
Note that this potentially could hide some bugs. In example bellow,
stscpy() will copy more than we should (1-3 extra uninitialized bytes):
char dst[8];
char *src;
src = kmalloc(5, GFP_KERNEL);
memset(src, 0xff, 5);
strscpy(dst, src, 8);

compiler.h: Add read_word_at_a_time() function.
Sometimes we know that it's safe to do potentially out-of-bounds access because we know it won't cross a page boundary. Still, KASAN will report this as a bug. Add read_word_at_a_time() function which is supposed to be used in such cases. In read_word_at_a_time() KASAN performs relaxed check - only the first byte of access is validated.

ibmvnic: fix firmware version when no firmware level has been provided by the VIOS server
Older versions of VIOS servers do not send the firmware level in the VPD
buffer for the ibmvnic driver. Thus, not only the current message is mis-
leading but the firmware version in the ethtool will be NULL. Therefore,
this patch fixes the firmware string and its warning.

Kconfig updates for v4.16
A pretty big batch of Kconfig updates. I have to mention the lexer
and parser of Kconfig are now built from real .l and .y sources.
So, flex and bison are the requirement for building the kernel.
Both of them (unlike gperf) have been stable for a long time. This
change has been tested several weeks in linux-next, and I did not
receive any problem report about this.
Summary:
- Add checks for mistakes, like the choice default is not in
choice, help is doubled
- Document data structure and complex code
- Fix various memory leaks
- Change Makefile to build lexer and parser instead of using
pre-generated C files
- Drop 'boolean' keyword, which is equivalent to 'bool'
- Use default 'yy' prefix and remove unneeded Make variables
- Fix gettext() check for xconfig
- Announce that oldnoconfig will be finally removed
- Make 'Selected by:' and 'Implied by' readable in help and
search result
- Hide silentoldconfig from 'make help' to stop confusing people
- Fix misc things and cleanups

Char/Misc driver patches for 4.16-rc1
Here is the big pull request for char/misc drivers for 4.16-rc1. There's a lot of stuff in here. Three new driver subsystems were added for various types of hardware busses: - siox - slimbus - soundwire as well as a new vboxguest subsystem for the VirtualBox hypervisor drivers. There's also big updates from the FPGA subsystem, lots of Android binder fixes, the usual handful of hyper-v updates, and lots of other smaller driver updates. All of these have been in linux-next for a long time, with no reported issues.

gfs2: Glock dump performance regression fix
Restore an optimization removed in commit 7f19449553 "Fix debugfs glocks dump": keep the glock hash table iterator active while the glock dump file is held open. This avoids having to rescan the hash table from the start for each read, with quadratically rising runtime. In addition, use rhastable_walk_peek for resuming a glock dump at the current position: when a glock doesn't fit in the provided buffer anymore, the next read must revisit the same glock. Finally, also restart the dump from the first entry when we notice that the hash table has been resized in gfs2_glock_seq_start.
