Back in January I posted patches to create function based events. These were
the events that you suggested I make to allow developers to easily create
events in code where no trace event exists. After posting those changes for
review, it was suggested that we implement this instead with kprobes.
The problem with kprobes is that the interface is too complex and needs to
be simplified. Masami Hiramatsu posted patches in March and I've been
playing with them a bit. There's been a bit of clean up in the kprobe code
that was inspired by the function based event patches, and a couple of
enhancements to the kprobe event interface.
- If the arch supports it (we added support for x86), you can place a
kprobe event at the start of a function and use $arg1, $arg2, etc
to reference the arguments of a function. (Before you needed to know
what register or where on the stack the argument was).
- The second is a way to see array of events. For example, if you reference
a mac address, you can add:
echo 'p:mac ip_rcv perm_addr=+574($arg2):x8[6]' > kprobe_events
And this will produce:
mac: (ip_rcv+0x0/0x140) perm_addr={0x52,0x54,0x0,0xc0,0x76,0xec}
Other changes include
- Exporting trace_dump_stack to modules
- Have the stack tracer trace the entire stack (stop trying to remove
tracing itself, as we keep removing too much).
- Added support for SDT in uprobes

This contains a series of patches that reworks the memory carveout
handling in remoteproc, in order to allow this to be reused for
statically allocated memory regions to be used for e.g. firmware.
It adds support for audio DSP (both TZ-assisted and non-TZ assisted) and
compute DSP on Qualcomm SDM845, TZ-assisted audio DSP, compute DSP and
WiFi processor on Qualcomm QCS404 and through some renaming of the
drivers cleans up the naming situation.
Finally support for custom coreudmp segment handlers is added and
is used in the Qualcomm modem remoteproc driver to gather memory dumps
of the firmware.

Plumb in a remap flag that enables the filesystem remap handler to
shorten remapping requests for callers that can handle it. Now
copy_file_range can report partial success (in case we run up against
alignment problems, resource limits, etc.).
We also enable CAN_SHORTEN for fideduperange to maintain existing
userspace-visible behavior where xfs/btrfs shorten the dedupe range to
avoid stale post-eof data exposure.

Change the remap_file_range functions to take a number of bytes to
operate upon and return the number of bytes they operated on. This is a
requirement for allowing fs implementations to return short clone/dedupe
results to the user, which will enable us to obey resource limits in a
graceful manner.
A subsequent patch will enable copy_file_range to signal to the
->clone_file_range implementation that it can handle a short length,
which will be returned in the function's return value. For now the
short return is not implemented anywhere so the behavior won't change --
either copy_file_range manages to clone the entire range or it tries an
alternative.
Neither clone ioctl can take advantage of this, alas.

There are close to 800 indivudal changesets in this branch again, which
feels like a lot. There are particularly many changes for the NVIDIA
Tegra platform this time, in fact more than it has seen in the two years
since the v4.9 merge window. Aside from this, it's been fairly normal,
with lots of changes going into Renesas R-CAR, NXP i.MX, Allwinner Sunxi,
Samsung Exynos, and TI OMAP.
Most of the changes are for adding new features into existing boards,
for brevity I'm only mentioning completely new machines and SoCs here.
For the first time I think we have (slightly) more new 64-bit hardware
than 32-bit:
Two boards get added for TI OMAP: Moxa UC-2101 is an industrial
computer, see https://www.moxa.com/product/UC-2100.htm; GTA04A5
is a minor variation of the motherboards of the GTA04 phone, see
https://shop.goldelico.com/wiki.php?page=GTA04A5
Clearfog is a nice little board for quad-core
Marvell Armada 8040 network processor, see
https://www.solid-run.com/marvell-armada-family/clearfog-gt-8k/
Two additional server boards come with the Aspeed baseboard management
controllers: Stardragon4800 is an arm64 reference platform made by HXT
(based on Qualcomm's server chips), and TiogaPass is an Open Compute
mainboard with x86 CPUs. Both use the ARM11 based AST2500 chips in
the BMC.
NXP i.MX usually sees a lot of new boards each release. This time there
we only add one minor variant: ConnectCore 6UL SBC Pro uses the same
SoM design as the ConnectCore 6UL SBC Express added later. However,
there is a new chip, the i.MX6ULZ, which is an even smaller variant
of the i.MX6ULL, with features removed. There is also support for the
reference board design, the i.MX6ULZ 14x14 EVK.
A new Raspberry Pi variant gets added, this one is the CM3 compute module
based on bcm2837, it was launched in early 2017 but only now added to
the kernel, both as 32-bit and as 64-bit files, as we tend to do for
Raspberry Pi.
On the Allwinner side, everything is again about cheap development
boards, usually of the "Fruit Pi" variety. The new ones this time
are:
Orange Pi Zero Plus2: http://www.orangepi.org/OrangePiZeroPlus2/
Orange Pi One Plus: http://www.orangepi.org/OrangePiOneplus/
Pine64 LTS: https://www.pine64.org/?product=pine-a64-lts
Banana Pi M2+ H5: http://www.banana-pi.org/m2plus.html
The last one of these is now a 64-bit version of the earlier Banana
Pi M2+ H3, with the same board layout.
Similarly, for Rockchips, get get another variant of the 32-bit
Asus Tinker board, the model 'S' based on rk3288, and three now
boards based on the popular RK3399 chip:
ROC-RK3399-PC: https://libre.computer/products/boards/roc-rk3399-pc/
Rock960: https://www.96boards.org/product/rock960/
RockPro64: https://www.pine64.org/?page_id=61454
These are all quite powerful boards with lots of RAM and I/O, and
the RK3399 is the same chip used in several Chromebooks. Finally,
we get support for the PX30 (aka rk3326) chip, which is based on the
low-end 64-bit Cortex-A35 CPU core. So far, only the evaluation board
is supported.
One more Banana Pi is added with a Mediatek chip: Banana Pi R64 is based
on the MT7622 WiFi router platform, and the first product I've seen with
a 64-bit Mediatek chip in that market: http://www.banana-pi.org/r64.html
For HiSilicon, we gain support for the Hi3670 SoC and HiKey 370
development board, which are similar to the Hi3660 and Hikey 360
respectively, but add support for an NPU.
Amlogic gets initial support for the Meson-G12A chip (S905D2),
another quad-core Cortex-A53 SoC, and its evaluation platform.
On the 32-bit side, we gain support for an actual end-user product,
the Endless Computers Endless Mini based on Meson8b (S805), see
https://endlessos.com/computers/
Qualcomm adds support for their MSM8998 SoC and evaluation platform. This
chip is commonly known as the Snapdragon 835, and is used in high-end
phones as well as low-end laptops.
For Renesas, a very bare support for the r8a774a1 (RZ/G2M) is added,
but no boards for this one. However, we do add boards for the previously
added r8a77965 (R-Car M3-N): the M3NULCB Kingfisher and the M3NULCB
Starter Kit Pro.
While we have lots of DT changes for NVIDIA to update the existing files,
the only board that gets added is the Toradex Colibri T20 on Colibri
Evaluation Board for the old Tegra2.
Synaptics add support for their AS370 SoC, which is part of the (formerly
Marvell) Berlin line of set-top-box chips used e.g. in the various Google
Chromecast. Only the .dtsi gets added at this point, no actual machines.

Merge tag 'armsoc-dt' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM SoC device tree updates from Arnd Bergmann:
"There are close to 800 indivudal changesets in this branch again,
which feels like a lot. There are particularly many changes for the
NVIDIA Tegra platform this time, in fact more than it has seen in the
two years since the v4.9 merge window. Aside from this, it's been
fairly normal, with lots of changes going into Renesas R-CAR, NXP
i.MX, Allwinner Sunxi, Samsung Exynos, and TI OMAP.
Most of the changes are for adding new features into existing boards,
for brevity I'm only mentioning completely new machines and SoCs here.
For the first time I think we have (slightly) more new 64-bit hardware
than 32-bit:
Two boards get added for TI OMAP: Moxa UC-2101 is an industrial
computer, see https://www.moxa.com/product/UC-2100.htm; GTA04A5 is a
minor variation of the motherboards of the GTA04 phone, see
https://shop.goldelico.com/wiki.php?page=GTA04A5
Clearfog is a nice little board for quad-core Marvell Armada 8040
network processor, see
https://www.solid-run.com/marvell-armada-family/clearfog-gt-8k/
Two additional server boards come with the Aspeed baseboard management
controllers: Stardragon4800 is an arm64 reference platform made by HXT
(based on Qualcomm's server chips), and TiogaPass is an Open Compute
mainboard with x86 CPUs. Both use the ARM11 based AST2500 chips in the
BMC.
NXP i.MX usually sees a lot of new boards each release. This time
there we only add one minor variant: ConnectCore 6UL SBC Pro uses the
same SoM design as the ConnectCore 6UL SBC Express added later.
However, there is a new chip, the i.MX6ULZ, which is an even smaller
variant of the i.MX6ULL, with features removed. There is also support
for the reference board design, the i.MX6ULZ 14x14 EVK.
A new Raspberry Pi variant gets added, this one is the CM3 compute
module based on bcm2837, it was launched in early 2017 but only now
added to the kernel, both as 32-bit and as 64-bit files, as we tend to
do for Raspberry Pi.
On the Allwinner side, everything is again about cheap development
boards, usually of the "Fruit Pi" variety. The new ones this time are:
- Orange Pi Zero Plus2: http://www.orangepi.org/OrangePiZeroPlus2/
- Orange Pi One Plus: http://www.orangepi.org/OrangePiOneplus/
- Pine64 LTS: https://www.pine64.org/?product=pine-a64-lts
- Banana Pi M2+ H5: http://www.banana-pi.org/m2plus.html
The last one of these is now a 64-bit version of the earlier Banana Pi
M2+ H3, with the same board layout.
Similarly, for Rockchips, get get another variant of the 32-bit Asus
Tinker board, the model 'S' based on rk3288, and three now boards
based on the popular RK3399 chip:
- ROC-RK3399-PC: https://libre.computer/products/boards/roc-rk3399-pc/
- Rock960: https://www.96boards.org/product/rock960/
- RockPro64: https://www.pine64.org/?page_id=61454
These are all quite powerful boards with lots of RAM and I/O, and the
RK3399 is the same chip used in several Chromebooks. Finally, we get
support for the PX30 (aka rk3326) chip, which is based on the low-end
64-bit Cortex-A35 CPU core. So far, only the evaluation board is
supported.
One more Banana Pi is added with a Mediatek chip: Banana Pi R64 is
based on the MT7622 WiFi router platform, and the first product I've
seen with a 64-bit Mediatek chip in that market:
http://www.banana-pi.org/r64.html
For HiSilicon, we gain support for the Hi3670 SoC and HiKey 370
development board, which are similar to the Hi3660 and Hikey 360
respectively, but add support for an NPU.
Amlogic gets initial support for the Meson-G12A chip (S905D2), another
quad-core Cortex-A53 SoC, and its evaluation platform. On the 32-bit
side, we gain support for an actual end-user product, the Endless
Computers Endless Mini based on Meson8b (S805), see
https://endlessos.com/computers/
Qualcomm adds support for their MSM8998 SoC and evaluation platform.
This chip is commonly known as the Snapdragon 835, and is used in
high-end phones as well as low-end laptops.
For Renesas, a very bare support for the r8a774a1 (RZ/G2M) is added,
but no boards for this one. However, we do add boards for the
previously added r8a77965 (R-Car M3-N): the M3NULCB Kingfisher and the
M3NULCB Starter Kit Pro.
While we have lots of DT changes for NVIDIA to update the existing
files, the only board that gets added is the Toradex Colibri T20 on
Colibri Evaluation Board for the old Tegra2.

various Google Chromecast. Only the .dtsi gets added at this point, no
actual machines"

anymore)
- vbox driver updates and fixes
- erofs fixes
- tons and tons of tiny checkpatch fixes for almost all staging

As far as I can tell the bindings that were added in commit
9c04400f7e ("dt-bindings: drm/panel: Document Innolux TV123WAM panel
bindings") weren't actually for Innolux TV123WAM but were actually for
Innolux P120ZDG-BF1.
As far as I can tell the Innolux TV123WAM isn't a real panel and but
it's a mosh between the TI TV123WAM and the Innolux P120ZDG-BF1.
Let's unmosh.
Here's my evidence:
* Searching for TV123WAM on the Internet turns up a TI panel. While
it's possible that an Innolux panel has the same model number as the
TI Panel, it seems a little doubtful. Looking up the datasheet from
the TI Panel shows that it's 1920 x 1280 and 259.2 mm x 172.8 mm.
* As far as I know, the patch adding the Innolux Panel was supposed to
be for the board that's sitting in front of me as I type this
(support for that board is not yet upstream). On the back of that
panel I see Innolux P120ZDZ-EZ1 rev B1.
* Someone pointed me at a datasheet that's supposed to be for the
panel in front of me (sorry, I can't share the datasheet). That
datasheet has the string "p120zdg-bf1"
* If I search for "P120ZDG-BF1" on the Internet I get hits for panels
that are 2160x1440. They don't have datasheets, but the fact that
the resolution matches is a good sign.
While we doing the rename, also mention that no-hpd can be used with
this panel. See the previous patch in this series ("drm/panel:
simple: Add "no-hpd" delay for Innolux TV123WAM").

Some eDP panels that are designed to be always connected to a board
use their HPD signal to signal that they've finished powering on and
they're ready to be talked to.
However, for various reasons it's possible that the HPD signal from
the panel isn't actually hooked up. In the case where the HPD isn't
hooked up you can look at the timing diagram on the panel datasheet
and insert a delay for the maximum amount of time that the HPD might
take to come up.
Let's add a property in the device tree for this concept.

Arnd acks, and adds the following notes:
"I did a thorough review of the ABI, which as usual mainly consists of
spotting any files that don't use the asm-generic ABI itself, and
having it changed to it matches exactly what we do on other new
architectures.
I also looked at every other patch and commented on maybe half of them
where I saw something that did not quite seem right. Others have
reviewed specific patches in greater depth. I'm sure that one could
fine more of the minor details, but as long as they are not ABI
relevant, they can be fixed later.
The only patch that is part of the ABI and that nobody reviewed is the
signal handling. This is one of the areas I never worked on in much
detail. I did not see anything wrong with it, but I also don't know
what the problems with the other architectures are here, and we seem
to be hitting issues occasionally, and we never managed to generalize
this enough for new architectures to have a trivial implementation.
I was originally hoping that we could have the 64-bit time_t
interfaces ready in time to completely drop the 32-bit ones, but that
did not happen. We might still remove them in the next merge window
depending on whether the libc upstream people prefer to keep them or
not.
One more general comment: I think this may well be the last new CPU
architecture we ever add to the kernel. Both nds32 and c-sky are made
by companies that also work on risc-v, and generally speaking risc-v
seems to be killing off any of the minor licensable instruction set
projects, just like ARM has mostly killed off the custom
vendor-specific instruction sets already.
If we add another architecture in the future, it may instead be
something like the LLVM bitcode or WebAssembly, who knows?"
To which Geert Uytterhoeven pipes in about another architecture still in
the pipeline: Kalray MPPA.

Pull XArray conversion from Matthew Wilcox:
"The XArray provides an improved interface to the radix tree data
structure, providing locking as part of the API, specifying GFP flags
at allocation time, eliminating preloading, less re-walking the tree,
more efficient iterations and not exposing RCU-protected pointers to
its users.
This patch set
1. Introduces the XArray implementation
2. Converts the pagecache to use it
3. Converts memremap to use it
The page cache is the most complex and important user of the radix
tree, so converting it was most important. Converting the memremap
code removes the only other user of the multiorder code, which allows
us to remove the radix tree code that supported it.
I have 40+ followup patches to convert many other users of the radix
tree over to the XArray, but I'd like to get this part in first. The
other conversions haven't been in linux-next and aren't suitable for
applying yet, but you can see them in the xarray-conv branch if you're
interested"

...
It was reported that on some of our machines containers were restarted
with OOM symptoms without an obvious reason. Despite there were almost no
memory pressure and plenty of page cache, MEMCG_OOM event was raised
occasionally, causing the container management software to think, that OOM
has happened. However, no tasks have been killed.
The following investigation showed that the problem is caused by a failing
attempt to charge a high-order page. In such case, the OOM killer is
never invoked. As shown below, it can happen under conditions, which are
very far from a real OOM: e.g. there is plenty of clean page cache and no
memory pressure.
There is no sense in raising an OOM event in this case, as it might
confuse a user and lead to wrong and excessive actions (e.g. restart the
workload, as in my case).
Let's look at the charging path in try_charge(). If the memory usage is
about memory.max, which is absolutely natural for most memory cgroups, we
try to reclaim some pages. Even if we were able to reclaim enough memory
for the allocation, the following check can fail due to a race with
another concurrent allocation:
if (mem_cgroup_margin(mem_over_limit) >= nr_pages)
goto retry;
For regular pages the following condition will save us from triggering
the OOM:
if (nr_reclaimed && nr_pages <= (1 << PAGE_ALLOC_COSTLY_ORDER))
goto retry;
But for high-order allocation this condition will intentionally fail. The
reason behind is that we'll likely fall to regular pages anyway, so it's
ok and even preferred to return ENOMEM.
In this case the idea of raising MEMCG_OOM looks dubious.
Fix this by moving MEMCG_OOM raising to mem_cgroup_oom() after allocation
order check, so that the event won't be raised for high order allocations.
This change doesn't affect regular pages allocation and charging.

Patch series "Address issues slowing persistent memory initialization", v5.
The main thing this patch set achieves is that it allows us to initialize
each node worth of persistent memory independently. As a result we reduce
page init time by about 2 minutes because instead of taking 30 to 40
seconds per node and going through each node one at a time, we process all
4 nodes in parallel in the case of a 12TB persistent memory setup spread
evenly over 4 nodes.
This patch (of 3):
On systems with a large amount of memory it can take a significant amount
of time to initialize all of the page structs with the PAGE_POISON_PATTERN
value. I have seen it take over 2 minutes to initialize a system with
over 12TB of RAM.
In order to work around the issue I had to disable CONFIG_DEBUG_VM and
then the boot time returned to something much more reasonable as the
arch_add_memory call completed in milliseconds versus seconds. However in
doing that I had to disable all of the other VM debugging on the system.
In order to work around a kernel that might have CONFIG_DEBUG_VM enabled
on a system that has a large amount of memory I have added a new kernel
parameter named "vm_debug" that can be set to "-" in order to disable it.

On a system that executes multiple cgrouped jobs and independent
workloads, we don't just care about the health of the overall system, but
also that of individual jobs, so that we can ensure individual job health,
fairness between jobs, or prioritize some jobs over others.
This patch implements pressure stall tracking for cgroups. In kernels
with CONFIG_PSI=y, cgroup2 groups will have cpu.pressure, memory.pressure,
and io.pressure files that track aggregate pressure stall times for only
the tasks inside the cgroup.

When systems are overcommitted and resources become contended, it's hard
to tell exactly the impact this has on workload productivity, or how close
the system is to lockups and OOM kills. In particular, when machines work
multiple jobs concurrently, the impact of overcommit in terms of latency
and throughput on the individual job can be enormous.
In order to maximize hardware utilization without sacrificing individual
job health or risk complete machine lockups, this patch implements a way
to quantify resource pressure in the system.
A kernel built with CONFIG_PSI=y creates files in /proc/pressure/ that
expose the percentage of time the system is stalled on CPU, memory, or IO,
respectively. Stall states are aggregate versions of the per-task delay
accounting delays:
cpu: some tasks are runnable but not executing on a CPU
memory: tasks are reclaiming, or waiting for swapin or thrashing cache
io: tasks are waiting for io completions
These percentages of walltime can be thought of as pressure percentages,
and they give a general sense of system health and productivity loss
incurred by resource overcommit. They can also indicate when the system
is approaching lockup scenarios and OOMs.
To do this, psi keeps track of the task states associated with each CPU
and samples the time they spend in stall states. Every 2 seconds, the
samples are averaged across CPUs - weighted by the CPUs' non-idle time to
eliminate artifacts from unused CPUs - and translated into percentages of
walltime. A running average of those percentages is maintained over 10s,
1m, and 5m periods (similar to the loadaverage).

The vmstat NR_KERNEL_MISC_RECLAIMABLE counter is for kernel non-slab
allocations that can be reclaimed via shrinker. In /proc/meminfo, we can
show the sum of all reclaimable kernel allocations (including slab) as
"KReclaimable". Add the same counter also to per-node meminfo under /sys
With this counter, users will have more complete information about kernel
memory usage. Non-slab reclaimable pages (currently just the ION
allocator) will not be missing from /proc/meminfo, making users wonder
where part of their memory went. More precisely, they already appear in
MemAvailable, but without the new counter, it's not obvious why the value
in MemAvailable doesn't fully correspond with the sum of other counters
participating in it.

Extend the slub_debug syntax to "slub_debug=<flags>[,<slub>]*", where
<slub> may contain an asterisk at the end. For example, the following
would poison all kmalloc slabs:
slub_debug=P,kmalloc*
and the following would apply the default flags to all kmalloc and all
block IO slabs:
slub_debug=,bio*,kmalloc*

Notable changes:
- A large series to rewrite our SLB miss handling, replacing a lot of fairly
complicated asm with much fewer lines of C.
- Following on from that, we now maintain a cache of SLB entries for each
process and preload them on context switch. Leading to a 27% speedup for our
context switch benchmark on Power9.
- Improvements to our handling of SLB multi-hit errors. We now print more debug
information when they occur, and try to continue running by flushing the SLB
and reloading, rather than treating them as fatal.
- Enable THP migration on 64-bit Book3S machines (eg. Power7/8/9).
- Add support for physical memory up to 2PB in the linear mapping on 64-bit
Book3S. We only support up to 512TB as regular system memory, otherwise the
percpu allocator runs out of vmalloc space.
- Add stack protector support for 32 and 64-bit, with a per-task canary.
- Add support for PTRACE_SYSEMU and PTRACE_SYSEMU_SINGLESTEP.
- Support recognising "big cores" on Power9, where two SMT4 cores are presented
to us as a single SMT8 core.
- A large series to cleanup some of our ioremap handling and PTE flags.
- Add a driver for the PAPR SCM (storage class memory) interface, allowing
guests to operate on SCM devices (acked by Dan).
- Changes to our ftrace code to handle very large kernels, where we need to use
a trampoline to get to ftrace_caller().
Many other smaller enhancements and cleanups.

(*) Query an asymmetric key.
long keyctl(KEYCTL_PKEY_QUERY,

Get information about an asymmetric key. The information is returned
in the keyctl_pkey_query struct:
__u32 supported_ops;
A bit mask of flags indicating which ops are supported. This is
constructed from a bitwise-OR of:
KEYCTL_SUPPORTS_{ENCRYPT,DECRYPT,SIGN,VERIFY}
__u32 key_size;
The size in bits of the key.
__u16 max_data_size;
__u16 max_sig_size;
__u16 max_enc_size;
__u16 max_dec_size;
The maximum sizes in bytes of a blob of data to be signed, a signature
blob, a blob to be encrypted and a blob to be decrypted.
reserved must be set to 0. This is intended for future use to hand
over one or more passphrases needed unlock a key.
If successful, 0 is returned. If the key is not an asymmetric key,
EOPNOTSUPP is returned.
(*) Encrypt, decrypt, sign or verify a blob using an asymmetric key.

const struct keyctl_pkey_params *params,
const char *info,
const void *in,
void *out);
long keyctl(KEYCTL_PKEY_DECRYPT,

long keyctl(KEYCTL_PKEY_VERIFY,
const struct keyctl_pkey_params *params,
const char *info,

Use an asymmetric key to perform a public-key cryptographic operation
a blob of data.
The parameter block pointed to by params contains a number of integer
values:
__s32 key_id;
__u32 in_len;
__u32 out_len;
__u32 in2_len;
For a given operation, the in and out buffers are used as follows:
Operation ID in,in_len out,out_len in2,in2_len

KEYCTL_PKEY_ENCRYPT Raw data Encrypted data -
KEYCTL_PKEY_DECRYPT Encrypted data Raw data -
KEYCTL_PKEY_SIGN Raw data Signature -
KEYCTL_PKEY_VERIFY Raw data - Signature
info is a string of key=value pairs that supply supplementary
information.
The __spare space in the parameter block must be set to 0. This is
intended, amongst other things, to allow the passing of passphrases
required to unlock a key.
If successful, encrypt, decrypt and sign all return the amount of data
written into the output buffer. Verification returns 0 on success.

Provide five new operations in the key_type struct that can be used to
provide access to asymmetric key operations. These will be implemented for
the asymmetric key type in a later patch and may refer to a key retained in
RAM by the kernel or a key retained in crypto hardware.
int (*asym_query)(const struct kernel_pkey_params *params,
struct kernel_pkey_query *info);
int (*asym_eds_op)(struct kernel_pkey_params *params,
const void *in, void *out);
int (*asym_verify_signature)(struct kernel_pkey_params *params,
const void *in, const void *in2);
Since encrypt, decrypt and sign are identical in their interfaces, they're
rolled together in the asym_eds_op() operation and there's an operation ID
in the params argument to distinguish them.
Verify is different in that we supply the data and the signature instead
and get an error value (or 0) as the only result on the expectation that
this may well be how a hardware crypto device may work.

Rick reported that the BPF JIT could potentially fill the entire module
space with BPF programs from unprivileged users which would prevent later
attempts to load normal kernel modules or privileged BPF programs, for
example. If JIT was enabled but unsuccessful to generate the image, then
before commit 290af86629 ("bpf: introduce BPF_JIT_ALWAYS_ON config")
we would always fall back to the BPF interpreter. Nowadays in the case
where the CONFIG_BPF_JIT_ALWAYS_ON could be set, then the load will abort
with a failure since the BPF interpreter was compiled out.
Add a global limit and enforce it for unprivileged users such that in case
of BPF interpreter compiled out we fail once the limit has been reached
or we fall back to BPF interpreter earlier w/o using module mem if latter
was compiled in. In a next step, fair share among unprivileged users can
be resolved in particular for the case where we would fail hard once limit
is reached.

There have been little changes in ALSA core stuff, but ASoC core still
kept rolling for the continued restructuring. The rest are lots of
small driver-specific changes and some minor API updates.
Here are highlights:
General:
- Appropriate fall-through annotations everywhere
- Some code cleanup in memalloc code, handling non-cacahed pages more
commonly in the helper
- Deployment of SNDRV_PCM_INFO_SYNC_APPLPTR flag consistently
Drivers:
- More HD-audio CA0132 codec improvement for supporting other Creative
boards
- Plumbing legacy HD-audio codecs as ASoC BE on Intel SST; this will
give move support of existing HD-audio devices with DSP
- A few device-specific HD-audio quirks as usual
- New quirk for RME CC devices and correction for B&W PX for USB-audio
- FireWire: code refactoring including devres usages
ASoC Core:
- Continued componentization works; it's almost done!
- A bunch of new for_each_foo macros
- Cleanups and fixes in DAPM code
ASoC Drivers:
- MCLK support for several different devices, including CS42L51, STM32
SAI, and MAX98373
- Support for Allwinner A64 CODEC analog, Intel boards with DA7219 and
MAX98927, Meson AXG PDM inputs, Nuvoton NAU8822, Renesas R8A7744 and

In this round, we've added 1) superblock checksum feature, 2) implemented new
mount option which we can disable/enable checkpoint to provide atomic updates of
entire filesystem, 3) refactored quota operations to enhance its consistency
along with checkpoint, 4) fixed subtle IO hang conditions and roll-forward
recovery flow to resurrect any fsync'ed inode metadata.
Enhancement:
- add checksum to keep superblock contents more safe
- add checkpoint=disable/enable to support A/B update of entire filesystem
- use plug for readahead IO in readdir
- add more IO counts to avoid block layer hacks
Bug fix:
- prevent data corruption issue for hardware encryption
- fix IO hang issues when GC is heavily triggered
- add missing up_read in __write_node_page
- recover inode metadata during roll-forward recovery flow
- fix null pointer dereference issue in wrongly configured discard map
There are some more sanity checks and minor bug fixes as well.

The Linux kernel security team has been accused of rejecting the idea of
security embargoes. This is incorrect, and could dissuade people from
reporting security issues to us under the false assumption that the
issue would leak prematurely.
Clarify the handling of embargoed information in our process
documentation.

With the preparations all being done this patch now enables authentication
support for UBIFS. Authentication is enabled when the newly introduced
auth_key and auth_hash_name mount options are passed. auth_key provides
the key which is used for authentication whereas auth_hash_name provides
the hashing algorithm used for this FS. Passing these options make
authentication mandatory and only UBIFS images that can be authenticated
with the given key are allowed.

Pull RCU updates from Ingo Molnar:
"The biggest change in this cycle is the conclusion of the big
'simplify RCU to two primary flavors' consolidation work - i.e.
there's a single RCU flavor for any kernel variant (PREEMPT and
!PREEMPT):
- Consolidate the RCU-bh, RCU-preempt, and RCU-sched flavors into a
single flavor similar to RCU-sched in !PREEMPT kernels and into a
single flavor similar to RCU-preempt (but also waiting on
preempt-disabled sequences of code) in PREEMPT kernels.
This branch also includes a refactoring of
rcu_{nmi,irq}_{enter,exit}() from Byungchul Park.
- Now that there is only one RCU flavor in any given running kernel,
the many "rsp" pointers are no longer required, and this cleanup
series removes them.
- This branch carries out additional cleanups made possible by the
RCU flavor consolidation, including inlining now-trivial
functions, updating comments and definitions, and removing
now-unneeded rcutorture scenarios.
- Now that there is only one flavor of RCU in any running kernel,
there is also only on rcu_data structure per CPU. This means that
the rcu_dynticks structure can be merged into the rcu_data
structure, a task taken on by this branch. This branch also
contains a -rt-related fix from Mike Galbraith.
There were also other updates:
- Documentation updates, including some good-eye catches from Joel
Fernandes.
- SRCU updates, most notably changes enabling call_srcu() to be
invoked very early in the boot sequence.
- Torture-test updates, including some preliminary work towards
making rcutorture better able to find problems that result in
insufficient grace-period forward progress.
- Initial changes to RCU to better promote forward progress of grace
periods, including fixing a bug found by Marius Hillenbrand and
David Woodhouse, with the fix suggested by Peter Zijlstra"

Merge tag 'leds-for-4.20-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/j.anaszewski/linux-leds
Pull LED updates from Jacek Anaszewski:
"We introduce LED pattern trigger - the idea that was proposed three
years ago now received enough attention and determination to drive it
to the successful end.
There is also one new LED class driver and couple of improvements to
the existing ones.
New LED class driver:
- add support for Panasonic AN30259A with related DT bindings
New LED trigger:
- introduce LED pattern trigger
leds-sc27xx-bltc:
- implement pattern_set/clear ops to enable support for pattern
trigger's hw_pattern sysfs file
Improvements to existing LED class drivers:
- leds-pwm: don't print error message on -EPROBE_DEFER
- leds-gpio: try to lookup gpiod from device
- leds-as3645a: convert to using %pOFn instead of device_node.name"
* tag 'leds-for-4.20-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/j.anaszewski/linux-leds:
leds: sc27xx: Add pattern_set/clear interfaces for LED controller
leds: core: Introduce LED pattern trigger
leds: add Panasonic AN30259A support
dt-bindings: leds: document Panasonic AN30259A bindings
leds: gpio: Try to lookup gpiod from device
leds: pwm: silently error out on EPROBE_DEFER
leds: Convert to using %pOFn instead of device_node.name
Core changes:
- A patch series from Hans Verkuil to make it possible to
enable/disable IRQs on a GPIO line at runtime and drive GPIO
lines as output without having to put/get them from scratch.
The irqchip callbacks have been improved so that they can
use only the fastpatch callbacks to enable/disable irqs
like any normal irqchip, especially the gpiod_lock_as_irq()
has been improved to be callable in fastpath context.
A bunch of rework had to be done to achieve this but it is
a big win since I never liked to restrict this to slowpath.
The only call requireing slowpath was try_module_get() and
this is kept at the .request_resources() slowpath callback.
In the GPIO CEC driver this is a big win sine a single
line is used for both outgoing and incoming traffic, and
this needs to use IRQs for incoming traffic while actively
driving the line for outgoing traffic.
- Janusz Krzysztofik improved the GPIO array API to pass a
"cookie" (struct gpio_array) and a bitmap for setting or
getting multiple GPIO lines at once. This improvement
orginated in a specific need to speed up an OMAP1 driver and
has led to a much better API and real performance gains
when the state of the array can be used to bypass a lot
of checks and code when we want things to go really fast.
The previous code would minimize the number of calls
down to the driver callbacks assuming the CPU speed was
orders of magnitude faster than the I/O latency, but this
assumption was wrong on several platforms: what we needed
to do was to profile and improve the speed on the hot
path of the array functions and this change is now
completed.
- Clean out the painful and hard to grasp BNF experiments
from the device tree bindings. Future approaches are looking
into using JSON schema for this purpose. (Rob Herring
is floating a patch series.)
New drivers:
- The RCAR driver now supports r8a774a1 (RZ/G2M).
- Synopsys GPIO via CREGs driver.
Major improvements:
- Modernization of the EP93xx driver to use irqdomain and
other contemporary concepts.
- The ingenic driver has been merged into the Ingenic pin
control driver and removed from the GPIO subsystem.
- Debounce support in the ftgpio010 driver.

bunch of small improvements in existing drivers:
- A new CS_WORD flag for transfers where the chip select is toggled
at every word, with both a generic implementation and the ability
for controllers to do this automatically (including a DaVinci one).
- New drivers for Mediatek MT2712, Qualcomm GENI and QSPI, Spreadtrum
SPI and ST STM32 QSPI plus new IDs for several existing ones"

Add a new mount option 'nocopyfrom' that will prevent the usage of the
RADOS 'copy-from' operation in cephfs. This could be useful, for example,
for an administrator to temporarily mitigate any possible bugs in the
'copy-from' implementation.
Currently, only copy_file_range uses this RADOS operation. Setting this
mount option will result in this syscall reverting to the default VFS
implementation, i.e. to perform the copies locally instead of doing remote
object copies.

The Contributor Covenant Code of Conduct is a general document meant to
provide a set of rules for almost any open source community. Every
open-source community is unique and the Linux kernel is no exception.
Because of this, this document describes how we in the Linux kernel
community will interpret it. We also do not expect this interpretation
to be static over time, and will adjust it as needed.
This document was created with the input and feedback of the TAB as well
as many current kernel maintainers.

As it was originally worded, this paragraph requires maintainers to
enforce the code of conduct, or face potential repercussions. It sends
the wrong message, when really we just want maintainers to be part of
the solution and not violate the code of conduct themselves.
Removing it doesn't limit our ability to enforce the code of conduct,
and we can still encourage maintainers to help maintain high standards
for the level of discourse in their subsystem.
