Its behaviour is identical to that of fs_value_is_filename.
It makes no sense, anyway - LOOKUP_EMPTY affects nothing
whatsoever once the pathname has been imported from userland.
And both fs_value_is_filename and fs_value_is_filename_empty
carry an already imported pathname.

This has been discussed thoroughly at Linux Plumbers.
Very useful for adding kprobes at bootup.
Only enabled if "bootconfig" is on the real kernel command line.
- Created dynamic event creation.
Merges common code between creating synthetic events and
kprobe events.
- Rename perf "ring_buffer" structure to "perf_buffer"
- Rename ftrace "ring_buffer" structure to "trace_buffer"
Had to rename existing "trace_buffer" to "array_buffer"
- Allow trace_printk() to work withing (some) tracing code.

As the bootconfig is appended to the initrd it is not as easy to modify as
the kernel command line. If there's some issue with the kernel, and the
developer wants to boot a pristine kernel, it should not be needed to modify
the initrd to remove the bootconfig for a single boot.
As bootconfig is silently added (if the admin does not know where to look
they may not know it's being loaded). It should be explicitly added to the
kernel cmdline. The loading of the bootconfig is only done if "bootconfig"
is on the kernel command line. This will let admins know that the kernel
command line is extended.
Note, after adding printk()s for when the size is too great or the checksum
is wrong, exposed that the current method always looked for the boot config,
and if this size and checksum matched, it would parse it (as if either is
wrong a printk has been added to show this). It's better to only check this
if the boot config is asked to be looked for.

This makes the qcom,videocc bindings match the recent changes to the
dispcc and gpucc.
1. Switched to using "bi_tcxo" instead of "xo".
2. Adds a description for the XO clock. Not terribly important but
nice if it cleanly matches its cousins.
3. Updates the example to use the symbolic name for the RPMH clock and
also show that the real devices are currently using 2 address cells
/ size cells and fixes the spacing on the closing brace.
4. Split into 2 files. In this case they could probably share one
file, but let's be consistent.

The qcom,gpucc bindings had a few problems with them:
1. When things were converted to yaml the name of the "gpll0 main"
clock got changed from "gpll0" to "gpll0_main". Change it back for
msm8998.
2. Apparently there is a push not to use purist aliases for clocks but
instead to just use the internal Qualcomm names. For sdm845 and
sc7180 (where the drivers haven't already been changed) move in
this direction.
Things were also getting complicated harder to deal with by jamming
several SoCs into one file. Splitting simplifies things.

The qcom,dispcc bindings had a few problems with them:
1. They didn't specify all the clocks that dispcc is a client of.
Specifically on sc7180 there are two clocks from the DSI PHY and
two from the DP PHY. On sdm845 there are actually two DSI PHYs
(each of which has two clocks) and an extra clock from the gcc.
These all need to be specified.
2. The sdm845.dtsi has existed for quite some time without specifying
the clocks. The Linux driver was relying on global names to match
things up. While we should transition things, it should be noted
in the bindings.
3. The names used the bindings for "xo" and "gpll0" didn't match the
names that QC used for these clocks internally and this was causing
confusion / difficulty with their code generation tools. Switched
to the internal names to simplify everyone's lives. It's not quite
as clean in a purist sense but it should avoid headaches. This
officially changes the binding, but that seems OK in this case.
Also note that I updated the example.

the normal collection of driver updates to support new SoCs, fix incorrect
data, and convert various drivers to clk_hw based APIs.
In the core, we allow clk_ops::init() to return an error code now so that we
can fail clk registration if the callback does something like fail to allocate
memory. We also add a new "terminate" clk_op so that things done in
clk_ops::init() can be undone, e.g. free memory. We also spit out a warning now
when critical clks fail to enable and we support changing clk rates and
enable/disable state through debugfs when developers compile the kernel
themselves.
On the driver front, we get support for what seems like a lot of Qualcomm and
NXP SoCs given that those vendors dominate the diffstat. There are a couple new
drivers for Xilinx and Amlogic SoCs too. The updates are all small things like
fixing the way glitch free muxes switch parents, avoiding div-by-zero problems,
or fixing data like parent names. See the updates section below for more
details.
Finally, the "basic" clk types have been converted to support specifying
parents with clk_hw pointers. This work includes an overhaul of the fixed-rate
clk type to be more modern by using clk_hw APIs.
Core:
- Let clk_ops::init() return an error code
- Add a clk_ops::terminate() callback to undo clk_ops::init()
- Warn about critical clks that fail to enable or prepare
- Support dangerous debugfs actions on clks with dead code
New Drivers:
- Support for Xilinx Versal platform clks
- Display clk controller on qcom sc7180
- Video clk controller on qcom sc7180
- Graphics clk controller on qcom sc7180
- CPU PLLs for qcom msm8916
- Move qcom msm8974 gfx3d clk to RPM control
- Display port clk support on qcom sdm845 SoCs
- Global clk controller on qcom ipq6018
- Add a driver for BCLK of Freescale SAI cores
- Add cam, vpe and sgx clock support for TI dra7
- Add aess clock support for TI omap5

- Add Amlogic meson8b DDR clock controller
- Add input clocks to Amlogic meson8b controllers
- Add SPIBSC (SPI FLASH) clock on Renesas RZ/A2
- i.MX8MP clk driver support
Updates:
- Convert gpio, fixed-factor, mux, gate, divider basic clks to hw based APIs
- Detect more PRMCU variants in ux500 driver
- Adjust the composite clk type to new way of describing clk parents
- Fixes for clk controllers on qcom msm8998 SoCs

Pull clk updates from Stephen Boyd:
"There are a few changes to the core framework this time around, in
addition to the normal collection of driver updates to support new
SoCs, fix incorrect data, and convert various drivers to clk_hw based
APIs.
In the core, we allow clk_ops::init() to return an error code now so
that we can fail clk registration if the callback does something like
fail to allocate memory. We also add a new "terminate" clk_op so that
things done in clk_ops::init() can be undone, e.g. free memory. We
also spit out a warning now when critical clks fail to enable and we
support changing clk rates and enable/disable state through debugfs
when developers compile the kernel themselves.
On the driver front, we get support for what seems like a lot of
Qualcomm and NXP SoCs given that those vendors dominate the diffstat.
There are a couple new drivers for Xilinx and Amlogic SoCs too. The
updates are all small things like fixing the way glitch free muxes
switch parents, avoiding div-by-zero problems, or fixing data like
parent names. See the updates section below for more details.
Finally, the "basic" clk types have been converted to support
specifying parents with clk_hw pointers. This work includes an
overhaul of the fixed-rate clk type to be more modern by using clk_hw
APIs.
Core:
- Let clk_ops::init() return an error code
- Add a clk_ops::terminate() callback to undo clk_ops::init()
- Warn about critical clks that fail to enable or prepare
- Support dangerous debugfs actions on clks with dead code
New Drivers:
- Support for Xilinx Versal platform clks
- Display clk controller on qcom sc7180
- Video clk controller on qcom sc7180
- Graphics clk controller on qcom sc7180
- CPU PLLs for qcom msm8916
- Move qcom msm8974 gfx3d clk to RPM control
- Display port clk support on qcom sdm845 SoCs
- Global clk controller on qcom ipq6018
- Add a driver for BCLK of Freescale SAI cores
- Add cam, vpe and sgx clock support for TI dra7
- Add aess clock support for TI omap5
- Enable clks for CPUfreq on Allwinner A64 SoCs
- Add Amlogic meson8b DDR clock controller
- Add input clocks to Amlogic meson8b controllers
- Add SPIBSC (SPI FLASH) clock on Renesas RZ/A2
- i.MX8MP clk driver support
Updates:
- Convert gpio, fixed-factor, mux, gate, divider basic clks to hw
based APIs
- Detect more PRMCU variants in ux500 driver
- Adjust the composite clk type to new way of describing clk parents
- Fixes for clk controllers on qcom msm8998 SoCs
- Fix gmac main clock for TI dra7
- Move TI dra7-atl clock header to correct location
- Fix hidden node name dependency on TI clkctrl clocks
- Fix Amlogic meson8b mali clock update using the glitch free mux

The 'qcom,gcc.yaml' file failed self-validation (dt_binding_check)
because it required a property to be either (3 entries big),
(3 entries big), or (7 entries big), but not more than one of those
things. That didn't make a ton of sense.
This patch splits all of the exceptional device trees (AKA those that
would have needed if/then/else rules) from qcom,gcc.yaml. It also
cleans up some cruft found while doing that.
After this lands, this worked for me atop clk-next with just the known
error about msm8998:
for f in \
Documentation/devicetree/bindings/clock/qcom,gcc-apq8064.yaml \
Documentation/devicetree/bindings/clock/qcom,gcc-ipq8074.yaml \

Documentation/devicetree/bindings/clock/qcom,gcc-sm8150.yaml \
Documentation/devicetree/bindings/clock/qcom,gcc.yaml; do \
ARCH=arm64 make dtbs_check DT_SCHEMA_FILES=$f; \
done
I then picked this patch atop linux-next (next-20200129) and ran:
# Delete broken yaml:
rm Documentation/devicetree/bindings/pci/intel-gw-pcie.yaml
ARCH=arm64 make dt_binding_check | grep 'clock/qcom'
...and that didn't seem to indicate problems.
Arbitrary decisions made (yell if you want changed):
- Left all the older devices (where clocks / clock-names weren't
specified) in a single file.
- Didn't make clocks "required" for msm8996 but left them as listed.
This seems a little weird but it matches the old binding.
Misc cleanups as part of this patch:
- Fixed schema id to not have "bindings/" as per Rob [1].
- Listed include files as per Stephen.
- sm8150 was claimed to be same set of clocks as sc7180, but driver
and dts appear to say that "bi_tcxo_ao" doesn't exist. Fixed.
- In "apq8064", "#thermal-sensor-cells" was missing the "#".
- Got rid of "|" at the end of top description since spacing doesn't
matter.
- Changed indentation to consistently 2 spaces (it was 3 in some
places).
- Added period at the end of protected-clocks description.
- No space before ":".
- Updated sc7180/sm8150 example to use the 'qcom,rpmh.h' include.
- Updated sc7180/sm8150 example to use larger address/size cells as
per reality.
- Updated sc7180/sm8150 example to point to the sleep_clk rather than
<0>.
- Made it so that gcc-ipq8074 didn't require #power-domain-cells since
actual dts didn't have it and I got no hits from:
git grep _GDSC include/dt-bindings/clock/qcom,gcc-ipq8074.h
- Made it so that gcc-qcs404 didn't require #power-domain-cells since
actual dts didn't have it and I got no hits from:
git grep _GDSC include/dt-bindings/clock/qcom,gcc-qcs404.h
Noticed, but not done in this patch (volunteers needed):
- Add "aud_ref_clk" to sm8150 bindings / dts even though I found a
reference to it in "gcc-sm8150.c".
- Fix node name in actual ipq8074 to be "clock-controller" (it's gcc).
- Since the example doesn't need phandes to exist, in msm8998 could
just make up places providing some of the clocks currently bogused
out with <0>.
- On msm8998 clocks are listed as required but current dts doesn't
have them.

In old days, the "host-progs" syntax was used for specifying host
programs. It was renamed to the current "hostprogs-y" in 2004.
It is typically useful in scripts/Makefile because it allows Kbuild to
selectively compile host programs based on the kernel configuration.
This commit renames like follows:
always -> always-y
hostprogs-y -> hostprogs
So, scripts/Makefile will look like this:
always-$(CONFIG_BUILD_BIN2C) += ...
always-$(CONFIG_KALLSYMS) += ...
...
hostprogs := $(always-y) $(always-m)
I think this makes more sense because a host program is always a host
program, irrespective of the kernel configuration. We want to specify
which ones to compile by CONFIG options, so always-y will be handier.
The "always", "hostprogs-y", "hostprogs-m" will be kept for backward
compatibility for a while.
Signed-off-by: Masahiro Yamada <masahiroy@kernel.org>
The difference between "always" and "extra-y" is that the targets
listed in $(always) are always built, whereas the ones in $(extra-y)
are built only when KBUILD_BUILTIN is set.
So, "make modules" does not build the targets in $(extra-y).
vmlinux.lds is only needed for linking vmlinux. So, adding it to extra-y
is more correct. In fact, arch/x86/kernel/Makefile does this.
Fix the example code.

There is some information in Documentation/power/interface.rst that
is still missing from Documentation/admin-guide/pm/sleep-states.rst
and really should be present in there, so update the latter by
adding that information to it and delete the former (as it becomes
redundant after that and it is somewhat outdated).
While at it, clean up some assorted pieces of sleep-states.rst a bit.

In certain system configurations it may not be desirable to use some
C-states assumed to be available by intel_idle and the driver needs
to be prevented from using them even before the cpuidle sysfs
interface becomes accessible to user space. Currently, the only way
to achieve that is by setting the 'max_cstate' module parameter to a
value lower than the index of the shallowest of the C-states in
question, but that may be overly intrusive, because it effectively
makes all of the idle states deeper than the 'max_cstate' one go
away (and the C-state to avoid may be in the middle of the range
normally regarded as available).
To allow that limitation to be overcome, introduce a new module
parameter called 'states_off' to represent a list of idle states to
be disabled by default in the form of a bitmask and update the
documentation to cover it.
Signed-off-by: Rafael J. Wysocki <rafael.j.wysocki@intel.com>
For diagnostics, it is generally useful to be able to make intel_idle
take the system's ACPI tables into consideration even if that is not
required for the processor model in there, so introduce a new module
parameter, 'use_acpi', to make that happen and update the documentation
to cover it.
While at it, fix the 'no_acpi' module parameter name in the
documentation.

zswap will always try to shrink pool when zswap is full. If there is a
high pressure on zswap it will result in flipping pages in and out zswap
pool without any real benefit, and the overall system performance will
drop. The previous discussion on this subject [1] ended up with a
suggestion to implement a sort of hysteresis to refuse taking pages into
zswap pool until it has sufficient space if the limit has been hit.
This is my take on this.
Hysteresis is controlled with a sysfs-configurable parameter (namely,
/sys/kernel/debug/zswap/accept_threhsold_percent). It specifies the
threshold at which zswap would start accepting pages again after it
became full. Setting this parameter to 100 disables the hysteresis and
sets the zswap behavior to pre-hysteresis state.

In order to provide a clearer, more symmetric API for pinning and
unpinning DMA pages. This way, pin_user_pages*() calls match up with
unpin_user_pages*() calls, and the API is a lot closer to being
self-explanatory.

Introduce pin_user_pages*() variations of get_user_pages*() calls, and
also pin_longterm_pages*() variations.
For now, these are placeholder calls, until the various call sites are
converted to use the correct get_user_pages*() or pin_user_pages*() API.
These variants will eventually all set FOLL_PIN, which is also
introduced, and thoroughly documented.
pin_user_pages()
pin_user_pages_remote()
pin_user_pages_fast()
All pages that are pinned via the above calls, must be unpinned via
put_user_page().
The underlying rules are:
* FOLL_PIN is a gup-internal flag, so the call sites should not directly
set it. That behavior is enforced with assertions.
* Call sites that want to indicate that they are going to do DirectIO
("DIO") or something with similar characteristics, should call a
get_user_pages()-like wrapper call that sets FOLL_PIN. These wrappers
will:
* Start with "pin_user_pages" instead of "get_user_pages". That
makes it easy to find and audit the call sites.
* Set FOLL_PIN
* For pages that are received via FOLL_PIN, those pages must be returned
via put_user_page().
Thanks to Jan Kara and Vlastimil Babka for explaining the 4 cases in
this documentation. (I've reworded it and expanded upon it.)

PPC: Bugfixes
x86:
* Support for mapping DAX areas with large nested page table entries.
* Cleanups and bugfixes here too. A particularly important one is
a fix for FPU load when the thread has TIF_NEED_FPU_LOAD. There is
also a race condition which could be used in guest userspace to exploit
the guest kernel, for which the embargo expired today.
* Fast path for IPI delivery vmexits, shaving about 200 clock cycles
from IPI latency.
* Protect against "Spectre-v1/L1TF" (bring data in the cache via
speculative out of bound accesses, use L1TF on the sibling hyperthread
to read it), which unfortunately is an even bigger whack-a-mole game
than SpectreV1.
Sean continues his mission to rewrite KVM. In addition to a sizable
number of x86 patches, this time he contributed a pretty large refactoring
of vCPU creation that affects all architectures but should not have any
visible effect.
s390 will come next week together with some more x86 patches.

The architecture states that we need to reset local IRQs for all CPU
resets. Because the old reset interface did not support the normal CPU
reset we never did that on a normal reset.
Let's implement an interface for the missing normal and clear resets
and reset all local IRQs, registers and control structures as stated
in the architecture.
Userspace might already reset the registers via the vcpu run struct,
but as we need the interface for the interrupt clearing part anyway,
we implement the resets fully and don't rely on userspace to reset the
rest.

In this series, we've implemented transparent compression experimentally. It
supports LZO and LZ4, but will add more later as we investigate in the field
more. At this point, the feature doesn't expose compressed space to user
directly in order to guarantee potential data updates later to the space.
Instead, the main goal is to reduce data writes to flash disk as much as
possible, resulting in extending disk life time as well as relaxing IO
congestion. Alternatively, we're also considering to add ioctl() to reclaim
compressed space and show it to user after putting the immutable bit.
Enhancement:
- add compression support
- avoid unnecessary locks in quota ops
- harden power-cut scenario for zoned block devices
- use private bio_set to avoid IO congestion
- replace GC mutex with rwsem to serialize callers
Bug fix:
- fix dentry consistency and memory corruption in rename()'s error case
- fix wrong swap extent reports
- fix casefolding bugs
- change lock coverage to avoid deadlock
- avoid GFP_KERNEL under f2fs_lock_op
And, we've cleaned up sysfs entries to prepare no debugfs.

From Boris Ostrovsky:
The KVM hypervisor may provide a guest with ability to defer remote TLB
flush when the remote VCPU is not running. When this feature is used,
the TLB flush will happen only when the remote VPCU is scheduled to run
again. This will avoid unnecessary (and expensive) IPIs.
Under certain circumstances, when a guest initiates such deferred action,
the hypervisor may miss the request. It is also possible that the guest
may mistakenly assume that it has already marked remote VCPU as needing
a flush when in fact that request had already been processed by the
hypervisor. In both cases this will result in an invalid translation
being present in a vCPU, potentially allowing accesses to memory locations
in that guest's address space that should not be accessible.
Note that only intra-guest memory is vulnerable.
The five patches address both of these problems:
1. The first patch makes sure the hypervisor doesn't accidentally clear
a guest's remote flush request
2. The rest of the patches prevent the race between hypervisor
acknowledging a remote flush request and guest issuing a new one.

memory after it is free'd. Also refactor code to disallow changing
the thin-pool's data device once in use -- doing so guarantees smae
lifetime of pool's data device relative to the pool metadata.

Pull openat2 support from Al Viro:
"This is the openat2() series from Aleksa Sarai.
I'm afraid that the rest of namei stuff will have to wait - it got
zero review the last time I'd posted #work.namei, and there had been a
leak in the posted series I'd caught only last weekend. I was going to
repost it on Monday, but the window opened and the odds of getting any
review during that... Oh, well.
Anyway, openat2 part should be ready; that _did_ get sane amount of
review and public testing, so here it comes"
From Aleksa's description of the series:
"For a very long time, extending openat(2) with new features has been
incredibly frustrating. This stems from the fact that openat(2) is
possibly the most famous counter-example to the mantra "don't silently
accept garbage from userspace" -- it doesn't check whether unknown
flags are present[1].
This means that (generally) the addition of new flags to openat(2) has
been fraught with backwards-compatibility issues (O_TMPFILE has to be
defined as __O_TMPFILE|O_DIRECTORY|[O_RDWR or O_WRONLY] to ensure old
kernels gave errors, since it's insecure to silently ignore the
flag[2]). All new security-related flags therefore have a tough road
to being added to openat(2).
Furthermore, the need for some sort of control over VFS's path
resolution (to avoid malicious paths resulting in inadvertent
breakouts) has been a very long-standing desire of many userspace
applications.
This patchset is a revival of Al Viro's old AT_NO_JUMPS[3] patchset
(which was a variant of David Drysdale's O_BENEATH patchset[4] which
was a spin-off of the Capsicum project[5]) with a few additions and
changes made based on the previous discussion within [6] as well as
others I felt were useful.
In line with the conclusions of the original discussion of
AT_NO_JUMPS, the flag has been split up into separate flags. However,
instead of being an openat(2) flag it is provided through a new
syscall openat2(2) which provides several other improvements to the
openat(2) interface (see the patch description for more details). The
following new LOOKUP_* flags are added:
LOOKUP_NO_XDEV:
Blocks all mountpoint crossings (upwards, downwards, or through
absolute links). Absolute pathnames alone in openat(2) do not
trigger this. Magic-link traversal which implies a vfsmount jump is
also blocked (though magic-link jumps on the same vfsmount are
permitted).
LOOKUP_NO_MAGICLINKS:
Blocks resolution through /proc/$pid/fd-style links. This is done
by blocking the usage of nd_jump_link() during resolution in a
filesystem. The term "magic-links" is used to match with the only
reference to these links in Documentation/, but I'm happy to change
the name.
It should be noted that this is different to the scope of
~LOOKUP_FOLLOW in that it applies to all path components. However,
you can do openat2(NO_FOLLOW|NO_MAGICLINKS) on a magic-link and it
will *not* fail (assuming that no parent component was a
magic-link), and you will have an fd for the magic-link.
In order to correctly detect magic-links, the introduction of a new
LOOKUP_MAGICLINK_JUMPED state flag was required.
LOOKUP_BENEATH:
Disallows escapes to outside the starting dirfd's
tree, using techniques such as ".." or absolute links. Absolute
paths in openat(2) are also disallowed.
Conceptually this flag is to ensure you "stay below" a certain
point in the filesystem tree -- but this requires some additional
to protect against various races that would allow escape using
"..".
Currently LOOKUP_BENEATH implies LOOKUP_NO_MAGICLINKS, because it
can trivially beam you around the filesystem (breaking the
protection). In future, there might be similar safety checks done
as in LOOKUP_IN_ROOT, but that requires more discussion.
In addition, two new flags are added that expand on the above ideas:
LOOKUP_NO_SYMLINKS:
Does what it says on the tin. No symlink resolution is allowed at
all, including magic-links. Just as with LOOKUP_NO_MAGICLINKS this
can still be used with NOFOLLOW to open an fd for the symlink as
long as no parent path had a symlink component.
LOOKUP_IN_ROOT:
This is an extension of LOOKUP_BENEATH that, rather than blocking
attempts to move past the root, forces all such movements to be
scoped to the starting point. This provides chroot(2)-like
protection but without the cost of a chroot(2) for each filesystem
operation, as well as being safe against race attacks that
chroot(2) is not.
If a race is detected (as with LOOKUP_BENEATH) then an error is
generated, and similar to LOOKUP_BENEATH it is not permitted to
cross magic-links with LOOKUP_IN_ROOT.
The primary need for this is from container runtimes, which
currently need to do symlink scoping in userspace[7] when opening
paths in a potentially malicious container.
There is a long list of CVEs that could have bene mitigated by
having RESOLVE_THIS_ROOT (such as CVE-2017-1002101,
CVE-2017-1002102, CVE-2018-15664, and CVE-2019-5736, just to name a
few).
In order to make all of the above more usable, I'm working on
libpathrs[8] which is a C-friendly library for safe path resolution.
It features a userspace-emulated backend if the kernel doesn't support
openat2(2). Hopefully we can get userspace to switch to using it, and
thus get openat2(2) support for free once it's ready.
Future work would include implementing things like
RESOLVE_NO_AUTOMOUNT and possibly a RESOLVE_NO_REMOTE (to allow
programs to be sure they don't hit DoSes though stale NFS handles)"

Here is the big staging/iio driver patches for 5.6-rc1
Included in here are:
- lots of new IIO drivers and updates for that subsystem
- the usual huge quantity of minor cleanups for staging drivers
- removal of the following staging drivers:
- isdn/avm
- isdn/gigaset
- isdn/hysdn
- octeon-usb
- octeon ethernet
Overall we deleted far more lines than we added, removing over 40k of
old and obsolete driver code.
All of these changes have been in linux-next for a while with no
reported issues.

Here is the big USB and Thunderbolt and PHY driver updates for 5.6-rc1.
With the advent of USB4, "Thunderbolt" has really become USB4, so the
renaming of the Kconfig option and starting to share subsystem code has
begun, hence both subsystems coming in through the same tree here.
PHY driver updates also touched USB drivers, so that is coming in
through here as well.
Major stuff included in here are:
- USB 4 initial support added (i.e. Thunderbolt)
- musb driver updates
- USB gadget driver updates
- PHY driver updates
- USB PHY driver updates
- lots of USB serial stuff fixed up
- USB typec updates
- USB-IP fixes
- lots of other smaller USB driver updates
All of these have been in linux-next for a while now (the usb-serial
tree is already tested in linux-next on its own before merged into
here), with no reported issues.

Each `blkif` has a free pages pool for the grant mapping. The size of
the pool starts from zero and is increased on demand while processing
the I/O requests. If current I/O requests handling is finished or 100
milliseconds has passed since last I/O requests handling, it checks and
shrinks the pool to not exceed the size limit, `max_buffer_pages`.
Therefore, host administrators can cause memory pressure in blkback by
attaching a large number of block devices and inducing I/O. Such
problematic situations can be avoided by limiting the maximum number of
devices that can be attached, but finding the optimal limit is not so
easy. Improper set of the limit can results in memory pressure or a
resource underutilization. This commit avoids such problematic
situations by squeezing the pools (returns every free page in the pool
to the system) for a while (users can set this duration via a module
parameter) if memory pressure is detected.
Discussions
===========
The `blkback`'s original shrinking mechanism returns only pages in the
pool which are not currently be used by `blkback` to the system. In
other words, the pages that are not mapped with granted pages. Because
this commit is changing only the shrink limit but still uses the same
freeing mechanism it does not touch pages which are currently mapping
grants.
Once memory pressure is detected, this commit keeps the squeezing limit
for a user-specified time duration. The duration should be neither too
long nor too short. If it is too long, the squeezing incurring overhead
can reduce the I/O performance. If it is too short, `blkback` will not
free enough pages to reduce the memory pressure. This commit sets the
value as `10 milliseconds` by default because it is a short time in
terms of I/O while it is a long time in terms of memory operations.
Also, as the original shrinking mechanism works for at least every 100
milliseconds, this could be a somewhat reasonable choice. I also tested
other durations (refer to the below section for more details) and
confirmed that 10 milliseconds is the one that works best with the test.
That said, the proper duration depends on actual configurations and
workloads. That's why this commit allows users to set the duration as a
module parameter.
Memory Pressure Test
====================
To show how this commit fixes the memory pressure situation well, I
configured a test environment on a xen-running virtualization system.
On the `blkfront` running guest instances, I attach a large number of
network-backed volume devices and induce I/O to those. Meanwhile, I
measure the number of pages that swapped in (pswpin) and out (pswpout)
on the `blkback` running guest. The test ran twice, once for the
`blkback` before this commit and once for that after this commit. As
shown below, this commit has dramatically reduced the memory pressure:
pswpin pswpout
before 76,672 185,799
after 867 3,967
Optimal Aggressive Shrinking Duration
-------------------------------------
To find a best squeezing duration, I repeated the test with three
different durations (1ms, 10ms, and 100ms). The results are as below:
duration pswpin pswpout
1 707 5,095
10 867 3,967
100 362 3,348
As expected, the memory pressure decreases as the duration increases,
but the reduction become slow from the `10ms`. Based on this results, I
chose the default duration as 10ms.
Performance Overhead Test
=========================
This commit could incur I/O performance degradation under severe memory
pressure because the squeezing will require more page allocations per
I/O. To show the overhead, I artificially made a worst-case squeezing
situation and measured the I/O performance of a `blkfront` running
guest.
For the artificial squeezing, I set the `blkback.max_buffer_pages` using
the `/sys/module/xen_blkback/parameters/max_buffer_pages` file. In this
test, I set the value to `1024` and `0`. The `1024` is the default
value. Setting the value as `0` is same to a situation doing the
squeezing always (worst-case).
If the underlying block device is slow enough, the squeezing overhead
could be hidden. For the reason, I use a fast block device, namely the
rbd[1]:
# xl block-attach guest phy:/dev/ram0 xvdb w
For the I/O performance measurement, I run a simple `dd` command 5 times
directly to the device as below and collect the 'MB/s' results.
$ for i in {1..5}; do dd if=/dev/zero of=/dev/xvdb \
bs=4k count=$((256*512)); sync; done
The results are as below. 'max_pgs' represents the value of the
`blkback.max_buffer_pages` parameter.
max_pgs Min Max Median Avg Stddev
0 417 423 420 419.4 2.5099801
1024 414 425 416 417.8 4.4384682
No difference proven at 95.0% confidence
In short, even worst case squeezing on ramdisk based fast block device
makes no visible performance degradation. Please note that this is just
a very simple and minimal test. On systems using super-fast block
devices and a special I/O workload, the results might be different. If
you have any doubt, test on your machine with your workload to find the
optimal squeezing duration for you.

Pull IMA updates from Mimi Zohar:
"Two new features - measuring certificates and querying IMA for a file
hash - and three bug fixes:
- Measuring certificates is like the rest of IMA, based on policy,
but requires loading a custom policy. Certificates loaded onto a
keyring, for example during early boot, before a custom policy has
been loaded, are queued and only processed after loading the custom
policy.
- IMA calculates and caches files hashes. Other kernel subsystems,
and possibly kernel modules, are interested in accessing these
cached file hashes.
The bug fixes prevent classifying a file short read (e.g. shutdown) as
an invalid file signature, add a missing blank when displaying the
securityfs policy rules containing LSM labels, and, lastly, fix the
handling of the IMA policy information for unknown LSM labels"

As diffstat shows we've had again a lot of works done for this cycle:
majority of changes are the continued componentization and code
refactoring in ASoC, the tree-wide PCM API updates and cleanups
and SOF updates while a few ASoC driver updates are seen, too.
Here we go, some highlights:
Core:
- Finally y2038 support landed to ALSA ABI;
some ioctls have been extended and lots of tricks were applied
- Applying the new managed PCM buffer API to all drivers;
the API itself was already merged in 5.5
- The already deprecated dimension support in ALSA control API is
dropped completely now
- Verification of ALSA control elements to catch API misuses
ASoC:
- Further code refactorings and moving things to the component level
- Lots of updates and improvements on SOF / Intel drivers;
now including common HDMI driver and SoundWire support
- New driver support for Ingenic JZ4770, Mediatek MT6660, Qualcomm
WCD934x and WSA881x, and Realtek RT700, RT711, RT715, RT1011, RT1015
and RT1308
HD-audio:
- Improved ring-buffer communications using waitqueue
- Drop the superfluous buffer preallocation on x86
Others:
- Many code cleanups, mostly constifications over the whole tree
- USB-audio: quirks for MOTU, Corsair Virtuoso, Line6 Helix
- FireWire: code refactoring for oxfw and dice drivers

- A mechanism to shield isolated tasks from managed interrupts:
The affinity of managed interrupts is completely controlled by the
kernel and user space has no influence on them. The reason is that
the automatically assigned affinity correlates to the multi-queue
CPU handling of block devices.
If the generated affinity mask spaws both housekeeping and isolated CPUs
the interrupt could be routed to an isolated CPU which would then be
disturbed by I/O submitted by a housekeeping CPU.
The new mechamism ensures that as long as one housekeeping CPU is online
in the assigned affinity mask the interrupt is routed to a housekeeping
CPU.
If there is no online housekeeping CPU in the affinity mask, then the
interrupt is routed to an isolated CPU to keep the device queue intact,
but unless the isolated CPU submits I/O by itself these interrupts are
not raised.

- Time namespace support:
If a container migrates from one host to another then it expects that
clocks based on MONOTONIC and BOOTTIME are not subject to
disruption. Due to different boot time and non-suspended runtime these
clocks can differ significantly on two hosts, in the worst case time
goes backwards which is a violation of the POSIX requirements.
The time namespace addresses this problem. It allows to set offsets for
clock MONOTONIC and BOOTTIME once after creation and before tasks are
associated with the namespace. These offsets are taken into account by
timers and timekeeping including the VDSO.
Offsets for wall clock based clocks (REALTIME/TAI) are not provided by
this mechanism. While in theory possible, the overhead and code
complexity would be immense and not justified by the esoteric potential
use cases which were discussed at Plumbers '18.
The overhead for tasks in the root namespace (host time offsets = 0) is
in the noise and great effort was made to ensure that especially in the
VDSO. If time namespace is disabled in the kernel configuration the
code is compiled out.
Kudos to Andrei Vagin and Dmitry Sofanov who implemented this feature
and kept on for more than a year addressing review comments, finding
better solutions. A pleasant experience.
- Overhaul of the alarmtimer device dependency handling to ensure that
the init/suspend/resume ordering is correct.
- A new clocksource/event driver for Microchip PIT64
- Suspend/resume support for the Hyper-V clocksource
- The usual pile of fixes, updates and improvements mostly in the
driver code.

Merge tag 'selinux-pr-20200127' of git://git.kernel.org/pub/scm/linux/kernel/git/pcmoore/selinux
Pull SELinux update from Paul Moore:
"This is one of the bigger SELinux pull requests in recent years with
28 patches. Everything is passing our test suite and the highlights
are below:
- Mark CONFIG_SECURITY_SELINUX_DISABLE as deprecated. We're some time
away from actually attempting to remove this in the kernel, but the
only distro we know that still uses it (Fedora) is working on
moving away from this so we want to at least let people know we are
planning to remove it.
- Reorder the SELinux hooks to help prevent bad things when SELinux
is disabled at runtime. The proper fix is to remove the
CONFIG_SECURITY_SELINUX_DISABLE functionality (see above) and just
take care of it at boot time (e.g. "selinux=0").
- Add SELinux controls for the kernel lockdown functionality,
introducing a new SELinux class/permissions: "lockdown { integrity
confidentiality }".
- Add a SELinux control for move_mount(2) that reuses the "file {
mounton }" permission.
- Improvements to the SELinux security label data store lookup
functions to speed up translations between our internal label
representations and the visible string labels (both directions).
- Revisit a previous fix related to SELinux inode auditing and
permission caching and do it correctly this time.
- Fix the SELinux access decision cache to cleanup properly on error.
In some extreme cases this could limit the cache size and result in
a decrease in performance.
- Enable SELinux per-file labeling for binderfs.
- The SELinux initialized and disabled flags were wrapped with
accessors to ensure they are accessed correctly.
- Mark several key SELinux structures with __randomize_layout.
- Changes to the LSM build configuration to only build
security/lsm_audit.c when needed.
- Changes to the SELinux build configuration to only build the IB
object cache when CONFIG_SECURITY_INFINIBAND is enabled.
- Move a number of single-caller functions into their callers.
- Documentation fixes (/selinux -> /sys/fs/selinux).
- A handful of cleanup patches that aren't worth mentioning on their
own, the individual descriptions have plenty of detail"
