ARM/arm64: dts: Rename SMB bus to just bus
Discussing the YAML validation schema with the DT maintainers it came out that a bus named "smb@80000000" is not really accepted, and the schema was written to name the static memory bus just "bus@80000000". This change is necessary for the schema to kick in and validate these device trees, else the schema gets ignored.

'dma-ranges' at the top level doesn't make sense. 'dma-ranges' implies there is a parent bus node with '#address-cells' and '#size-cells' which is impossible here.

kvm: arm/arm64: Fold VHE entry/exit work into kvm_vcpu_run_vhe()
With VHE, running a vCPU always requires the sequence: 1. kvm_arm_vhe_guest_enter(); 2. kvm_vcpu_run_vhe(); 3. kvm_arm_vhe_guest_exit() ... and as we invoke this from the shared arm/arm64 KVM code, 32-bit arm has to provide stubs for all three functions. To simplify the common code, and make it easier to make further modifications to the arm64-specific portions in the near future, let's fold kvm_arm_vhe_guest_enter() and kvm_arm_vhe_guest_exit() into kvm_vcpu_run_vhe(). The 32-bit stubs for kvm_arm_vhe_guest_enter() and kvm_arm_vhe_guest_exit() are removed, as they are no longer used. The 32-bit stub for kvm_vcpu_run_vhe() is left as-is. There should be no functional change as a result of this patch.

ARM: dts: renesas: Group tuples in operating-points properties
To improve human readability and enable automatic validation, the tuples in the "operating-points" properties of CPU nodes should be grouped. Fix this by grouping the tuples of these properties using angle brackets in the DTS files for all Renesas SoCs that don't already do so.

A set of fixes for the interrupt subsystem:
- Provision only ACPI enabled redistributors on GICv3
- Use the proper command colums when building the INVALL command for the
GICv3-ITS
- Ensure the allocation of the L2 vPE table for GICv4.1
- Correct the GICv4.1 VPROBASER programming so it uses the proper size
- A set of small GICv4.1 tidy up patches
- Configuration cleanup for C-SKY interrupt chip
- Clarify the function documentation for irq_set_wake() to document that
the wakeup functionality is orthogonal to the irq disable/enable
mechanism.

ARM: dma-api: fix max_pfn off-by-one error in __dma_supported()
max_pfn, as set in arch/arm/mm/init.c:
static void __init find_limits(unsigned long *min,
unsigned long *max_low,
unsigned long *max_high)
{
*max_low = PFN_DOWN(memblock_get_current_limit());
*min = PFN_UP(memblock_start_of_DRAM());
*max_high = PFN_DOWN(memblock_end_of_DRAM());
}
with memblock_end_of_DRAM() pointing to the next byte after DRAM. As
such, max_pfn points to the PFN after the end of DRAM.
Thus when using max_pfn to check DMA masks, we should subtract one when
checking DMA ranges against it.

asm-generic/tlb: provide MMU_GATHER_TABLE_FREE
As described in the comment, the correct order for freeing pages is: 1) unhook page 2) TLB invalidate page 3) free page This order equally applies to page directories. Currently there are two correct options: - use tlb_remove_page(), when all page directores are full pages and there are no futher contraints placed by things like software walkers (HAVE_FAST_GUP). - use MMU_GATHER_RCU_TABLE_FREE and tlb_remove_table() when the architecture does not do IPI based TLB invalidate and has HAVE_FAST_GUP (or software TLB fill). This however leaves architectures that don't have page based directories but don't need RCU in a bind. For those, provide MMU_GATHER_TABLE_FREE, which provides the independent batching for directories without the additional RCU freeing.

arm: mm: add p?d_leaf() definitions
walk_page_range() is going to be allowed to walk page tables other than those of user space. For this it needs to know when it has reached a 'leaf' entry in the page tables. This information is provided by the p?d_leaf() functions/macros. For arm pmd_large() already exists and does what we want. So simply provide the generic pmd_leaf() name.

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
- Fix Amlogic pll driver division by zero at init
- Prepare for split of Renesas R-Car H3 ES1.x and ES2.0+ config symbols
- Switch more i.MX clk drivers to clk_hw based APIs
- Disable non-functional divider between pll4_audio_div and
pll4_post_div on imx6q
- Fix watchdog2 clock name typo in imx7ulp clock driver
- Set CLK_GET_RATE_NOCACHE flag for DRAM related clocks on i.MX8M SoCs
- Suppress bind attrs for i.MX8M clock driver
- Add a big comment in imx8qxp-lpcg driver to tell why
devm_platform_ioremap_resource() shouldn't be used for the driver
- A correction on i.MX8MN usb1_ctrl parent clock setting

kbuild: rename hostprogs-y/always to hostprogs/always-y
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.

ARM: Cleanups and corner case fixes
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.

Pull thread management updates from Christian Brauner:
"Sargun Dhillon over the last cycle has worked on the pidfd_getfd()
syscall.
This syscall allows for the retrieval of file descriptors of a process
based on its pidfd. A task needs to have ptrace_may_access()
permissions with PTRACE_MODE_ATTACH_REALCREDS (suggested by Oleg and
Andy) on the target.
One of the main use-cases is in combination with seccomp's user
notification feature. As a reminder, seccomp's user notification
feature was made available in v5.0. It allows a task to retrieve a
file descriptor for its seccomp filter. The file descriptor is usually
handed of to a more privileged supervising process. The supervisor can
then listen for syscall events caught by the seccomp filter of the
supervisee and perform actions in lieu of the supervisee, usually
emulating syscalls. pidfd_getfd() is needed to expand its uses.
There are currently two major users that wait on pidfd_getfd() and one
future user:
- Netflix, Sargun said, is working on a service mesh where users
should be able to connect to a dns-based VIP. When a user connects
to e.g. 1.2.3.4:80 that runs e.g. service "foo" they will be
redirected to an envoy process. This service mesh uses seccomp user
notifications and pidfd to intercept all connect calls and instead
of connecting them to 1.2.3.4:80 connects them to e.g.
127.0.0.1:8080.
- LXD uses the seccomp notifier heavily to intercept and emulate
mknod() and mount() syscalls for unprivileged containers/processes.
With pidfd_getfd() more uses-cases e.g. bridging socket connections
will be possible.
- The patchset has also seen some interest from the browser corner.
Right now, Firefox is using a SECCOMP_RET_TRAP sandbox managed by a
broker process. In the future glibc will start blocking all signals
during dlopen() rendering this type of sandbox impossible. Hence,
in the future Firefox will switch to a seccomp-user-nofication
based sandbox which also makes use of file descriptor retrieval.
The thread for this can be found at
https://sourceware.org/ml/libc-alpha/2019-12/msg00079.html
With pidfd_getfd() it is e.g. possible to bridge socket connections
for the supervisee (binding to a privileged port) and taking actions
on file descriptors on behalf of the supervisee in general.
Sargun's first version was using an ioctl on pidfds but various people
pushed for it to be a proper syscall which he duely implemented as
well over various review cycles. Selftests are of course included.
I've also added instructions how to deal with merge conflicts below.
There's also a small fix coming from the kernel mentee project to
correctly annotate struct sighand_struct with __rcu to fix various
sparse warnings. We've received a few more such fixes and even though
they are mostly trivial I've decided to postpone them until after -rc1
since they came in rather late and I don't want to risk introducing
build warnings.
Finally, there's a new prctl() command PR_{G,S}ET_IO_FLUSHER which is
needed to avoid allocation recursions triggerable by storage drivers
that have userspace parts that run in the IO path (e.g. dm-multipath,
iscsi, etc). These allocation recursions deadlock the device.
The new prctl() allows such privileged userspace components to avoid
allocation recursions by setting the PF_MEMALLOC_NOIO and
PF_LESS_THROTTLE flags. The patch carries the necessary acks from the
relevant maintainers and is routed here as part of prctl()
thread-management."

Merge branch 'work.openat2' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs
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)"
* 'work.openat2' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs:
Documentation: path-lookup: include new LOOKUP flags
selftests: add openat2(2) selftests
open: introduce openat2(2) syscall

Merge tag 'pinctrl-v5.6-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl
Pull pin control updates from Linus Walleij:
"This is the bulk of pin control changes, nothing too exciting about
this.
Some changes hit arch/sh and arch/arm but are well isolated and
acknowledged by the respective arch maintainers.
Core changes:
- Dropped the chained IRQ setup callback into GPIOLIB as we got rid
of the last users of that in this changeset.
New drivers:
- New driver for Ingenic X1830.
- New driver for Freescale i.MX8MP.
Driver enhancements:
- Fix all remaining Intel drivers to pass their IRQ chips along with
the GPIO chips.
- Intel Baytrail allocates its irqchip dynamically.
- Intel Lynxpoint is thoroughly rewritten and modernized.
- Aspeed AST2600 pin muxing and configuration is much improved.
- Qualcomm SC7180 functions are updated and wakeup interrupt map is
provided.
- A whole slew of Renesas SH-PFC cleanups and improvements.
- Fix up the Intel DT bindings to use the generic YAML DT bindings
schema (a first user of this)"
