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.

- 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.

the init/suspend/resume ordering is correct.

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"

Pull power management updates from Rafael Wysocki:
"These add ACPI support to the intel_idle driver along with an admin
guide document for it, add support for CPR (Core Power Reduction) to
the AVS (Adaptive Voltage Scaling) subsystem, add new hardware support
in a few places, add some new sysfs attributes, debugfs files and
tracepoints, fix bugs and clean up a bunch of things all over.
Specifics:
- Update the ACPI processor driver in order to export
acpi_processor_evaluate_cst() to the code outside of it, add ACPI
support to the intel_idle driver based on that and clean up that
driver somewhat (Rafael Wysocki).
- Add an admin guide document for the intel_idle driver (Rafael
Wysocki).
- Clean up cpuidle core and drivers, enable compilation testing for
some of them (Benjamin Gaignard, Krzysztof Kozlowski, Rafael
Wysocki, Yangtao Li).
- Fix reference counting of OPP (operating performance points) table
structures (Viresh Kumar).

- Fix usage of a macro in loongson2_cpufreq (Alexandre Oliva).
- Fix cpufreq policy reference counting issues in s3c and
brcmstb-avs (chenqiwu).
- Fix ACPI table reference counting issue and HiSilicon quirk
handling in the CPPC driver (Hanjun Guo).
- Clean up spelling mistake in intel_pstate (Harry Pan).
- Convert the kirkwood and tegra186 drivers to using
devm_platform_ioremap_resource() (Yangtao Li).
- Update devfreq core:
- Add 'name' sysfs attribute for devfreq devices (Chanwoo Choi).
- Clean up the handing of transition statistics and allow them to
be reset by writing 0 to the 'trans_stat' devfreq device
attribute in sysfs (Kamil Konieczny).
- Add 'devfreq_summary' to debugfs (Chanwoo Choi).
- Clean up kerneldoc comments and Kconfig indentation (Krzysztof
Kozlowski, Randy Dunlap).
- Update devfreq drivers:
- Add dynamic scaling for the imx8m DDR controller and clean up
imx8m-ddrc (Leonard Crestez, YueHaibing).
- Fix DT node reference counting and nitialization error code path
in rk3399_dmc and add COMPILE_TEST and HAVE_ARM_SMCCC dependency
for it (Chanwoo Choi, Yangtao Li).
- Fix DT node reference counting in rockchip-dfi and make it use
devm_platform_ioremap_resource() (Yangtao Li).
- Fix excessive stack usage in exynos-ppmu (Arnd Bergmann).
- Fix initialization error code paths in exynos-bus (Yangtao Li).
- Clean up exynos-bus and exynos somewhat (Artur Świgoń, Krzysztof
Kozlowski).
- Add tracepoints for tracking usage_count updates unrelated to
status changes in PM-runtime (Michał Mirosław).
- Add sysfs attribute to control the "sync on suspend" behavior
during system-wide suspend (Jonas Meurer).
- Switch system-wide suspend tests over to 64-bit time (Alexandre
Belloni).
- Make wakeup sources statistics in debugfs cover deleted ones which
used to be the case some time ago (zhuguangqing).
- Clean up computations carried out during hibernation, update
messages related to hibernation and fix a spelling mistake in one
of them (Wen Yang, Luigi Semenzato, Colin Ian King).
- Add mailmap entry for maintainer e-mail address that has not been
functional for several years (Rafael Wysocki)"

Hardly anything going on in the core this time around with the regulator
API and pretty quiet on the driver front:
- An API for comparing regulators, useful for devices that need to
check if supply voltages exactly match rather than just nominally
match.
- Conversion of several DT bindings to YAML format.
- Conversion of I2C drivers to probe_new().
- New drivers for Monolithic MPQ7920 and MP8859, and Rohm BD71828.

The cpu idle cooling device offers a new method to cool down a CPU by
injecting idle cycles at runtime.
It has some similarities with the intel power clamp driver but it is
actually designed to be more generic and relying on the idle injection
powercap framework.
The idle injection duration is fixed while the running duration is
variable. That allows to have control on the device reactivity for the
user experience.
An idle state powering down the CPU or the cluster will allow to drop
the static leakage, thus restoring the heat capacity of the SoC. It
can be set with a trip point between the hot and the critical points,
giving the opportunity to prevent a hard reset of the system when the
cpufreq cooling fails to cool down the CPU.
With more sophisticated boards having a per core sensor, the idle
cooling device allows to cool down a single core without throttling
the compute capacity of several cpus belonging to the same clock line,
so it could be used in collaboration with the cpufreq cooling device.

Add mptcp_connect tool:
xmit two files back and forth between two processes, several net
namespaces including some adding delays, losses and reordering.
Wrapper script tests that data was transmitted without corruption.
The "-c" command line option for mptcp_connect.sh is there for debugging:
The script will use tcpdump to create one .pcap file per test case, named
according to the namespaces, protocols, and connect address in use.
For example, the first test case writes the capture to
ns1-ns1-MPTCP-MPTCP-10.0.1.1.pcap.
The stderr output from tcpdump is printed after the test completes to
show tcpdump's "packets dropped by kernel" information.
Also check that userspace can't create MPTCP sockets when mptcp.enabled
sysctl is off.
The "-b" option allows to tune/lower send buffer size.
"-m mmap" can be used to test blocking io. Default is non-blocking
io using read/write/poll.
Will run automatically on "make kselftest".
Note that the default timeout of 45 seconds is used even if there is a
"settings" changing it to 450. 45 seconds should be enough in most cases
but this depends on the machine running the tests.
A fix to correctly read the "settings" file has been proposed upstream
but not applied yet. It is not blocking the execution of these new tests
but it would be nice to have it:

Implements the infrastructure for MPTCP sockets.
MPTCP sockets open one in-kernel TCP socket per subflow. These subflow
sockets are only managed by the MPTCP socket that owns them and are not
visible from userspace. This commit allows a userspace program to open
an MPTCP socket with:
sock = socket(AF_INET, SOCK_STREAM, IPPROTO_MPTCP);
The resulting socket is simply a wrapper around a single regular TCP
socket, without any of the MPTCP protocol implemented over the wire.

has to be converted to yaml. In the new setup
rockchip-dw-mshc.yaml will inherit properties from
mmc-controller.yaml and synopsys-dw-mshc-common.yaml.
'dwmmc' will no longer be a valid name for a node and
should be changed to 'mmc'.

The idxd driver introduces the Intel Data Stream Accelerator [1] that will
be available on future Intel Xeon CPUs. One of the kernel access
point for the driver is through the dmaengine subsystem. It will initially
provide the DMA copy service to the kernel.
Some of the main functionality introduced with this accelerator
are: shared virtual memory (SVM) support, and descriptor submission using
Intel CPU instructions movdir64b and enqcmds. There will be additional
accelerator devices that share the same driver with variations to
capabilities.
This commit introduces the probe and initialization component of the
driver.

Convert the generic PCI host binding to DT schema. The derivative Juno,
PLDA XpressRICH3-AXI, and Designware ECAM bindings all just vary in
their compatible strings. The simplest way to convert those to
schema is just add them into the common generic PCI host schema.
The HiSilicon ECAM and Cavium ThunderX PEM bindings have an additional
'reg' entry, but are otherwise the same binding as well.

* Tiger Lake appears to have _HID enumeration, thus driver has been updated
* Coffee Lake-S has the same IP as Sunrisepoint, thus ID has been added
* Baytrail has got more clean ups and bug fixes, such as direct IRQ handling
* Lynxpoint GPIO has been converted to true pin control driver
* The common driver now uses IRQ chip enumeration via GPIO chip
The following is an automated git shortlog grouped by driver:
baytrail:
- Replace WARN with dev_info_once when setting direct-irq pin to output
- Do not clear IRQ flags on direct-irq enabled pins
- Reuse struct intel_pinctrl in the driver
- Use local variable to keep device pointer
- Keep pointer to struct device instead of its container
- Use GPIO direction definitions
- Move IRQ valid mask initialization to a dedicated callback
- Group GPIO IRQ chip initialization
- Allocate IRQ chip dynamic
cherryview:
- Use GPIO direction definitions
intel:
- Pass irqchip when adding gpiochip
- Add GPIO <-> pin mapping ranges via callback
- Share struct intel_pinctrl for wider use
- Use GPIO direction definitions
lynxpoint:
- Update summary in the driver
- Switch to pin control API
- Add GPIO <-> pin mapping ranges via callback
- Implement ->pin_dbg_show()
- Add pin control operations
- Reuse struct intel_pinctrl in the driver
- Add pin control data structures
- Implement intel_gpio_get_direction callback
- Implement ->irq_ack() callback
- Move ownership check to IRQ chip
- Move lp_irq_type() closer to IRQ related routines
- Move ->remove closer to ->probe()
- Extract lp_gpio_acpi_use() for future use
- Convert unsigned to unsigned int
- Switch to memory mapped IO accessors
- Keep pointer to struct device instead of its container
- Relax GPIO request rules
- Assume 2 bits for mode selector
- Use standard pattern for memory allocation
- Use %pR to print IO resource
- Drop useless assignment
- Correct amount of pins
- Use raw_spinlock for locking
- Move GPIO driver to pin controller folder
sunrisepoint:
- Add Coffee Lake-S ACPI ID
- Add missing Interrupt Status register offset
tigerlake:
- Tiger Lake uses _HID enumeration
