commit 5c02406428d5219c367c5f53457698c58bc5f917 upstream.
Otherwise a malicious user could (ab)use the "recalculate" feature
that makes dm-integrity calculate the checksums in the background
while the device is already usable. When the system restarts before all
checksums have been calculated, the calculation continues where it was
interrupted even if the recalculate feature is not requested the next
time the dm device is set up.
Disable recalculating if we use internal_hash or journal_hash with a
key (e.g. HMAC) and we don't have the "legacy_recalculate" flag.
This may break activation of a volume, created by an older kernel,
that is not yet fully recalculated -- if this happens, the user should
add the "legacy_recalculate" flag to constructor parameters.

commit 320d159e2d63a97a40f24cd6dfda5a57eec65b91 upstream.
Some RTCs, e.g. the pcf2127, can be used as a hardware watchdog. But
if the reset pin is not actually wired up, the driver exposes a
watchdog device that doesn't actually work.
Provide a standard binding that can be used to indicate that a given
RTC can perform a reset of the machine, similar to wakeup-source.

commit 39aead8373b3c20bb5965c024dfb51a94e526151 upstream.
So ever since syzbot discovered fbcon, we have solid proof that it's
full of bugs. And often the solution is to just delete code and remove
features, e.g. 50145474f6 ("fbcon: remove soft scrollback code").
Now the problem is that most modern-ish drivers really only treat
fbcon as an dumb kernel console until userspace takes over, and Oops
printer for some emergencies. Looking at drm drivers and the basic
vesa/efi fbdev drivers shows that only 3 drivers support any kind of
acceleration:
- nouveau, seems to be enabled by default
- omapdrm, when a DMM remapper exists using remapper rewriting for
y/xpanning
- gma500, but that is getting deleted now for the GTT remapper trick,
and the accelerated copyarea never set the FBINFO_HWACCEL_COPYAREA
flag, so unused (and could be deleted already I think).
No other driver supportes accelerated fbcon. And fbcon is the only
user of this accel code (it's not exposed as uapi through ioctls),
which means we could garbage collect fairly enormous amounts of code
if we kill this.
Plus because syzbot only runs on virtual hardware, and none of the
drivers for that have acceleration, we'd remove a huge gap in testing.
And there's no other even remotely comprehensive testing aside from
syzbot.
This patch here just disables the acceleration code by always
redrawing when scrolling. The plan is that once this has been merged
for well over a year in released kernels, we can start to go around
and delete a lot of code.

- Drop a few more unused local variables, somehow I missed the
compiler warnings (Sam)

[ Upstream commit 028c221ed1904af9ac3c5162ee98f48966de6b3d ]
AMD systems provide a "NodeId" value that represents a global ID
indicating to which "Node" a logical CPU belongs. The "Node" is a
physical structure equivalent to a Die, and it should not be confused
with logical structures like NUMA nodes. Logical nodes can be adjusted
based on firmware or other settings whereas the physical nodes/dies are
fixed based on hardware topology.
The NodeId value can be used when a physical ID is needed by software.
Save the AMD NodeId to struct cpuinfo_x86.cpu_die_id. Use the value
from CPUID or MSR as appropriate. Default to phys_proc_id otherwise.
Do so for both AMD and Hygon systems.
Drop the node_id parameter from cacheinfo_*_init_llc_id() as it is no
longer needed.
Update the x86 topology documentation.

Commit cae7ed3c2c ("KVM: x86: Refactor the MMIO SPTE generation handling")
cleaned up the computation of MMIO generation SPTE masks, however it
introduced a bug how the upper part was encoded:
SPTE bits 52-61 were supposed to contain bits 10-19 of the current
generation number, however a missing shift encoded bits 1-10 there instead
(mostly duplicating the lower part of the encoded generation number that
then consisted of bits 1-9).
In the meantime, the upper part was shrunk by one bit and moved by
subsequent commits to become an upper half of the encoded generation number
(bits 9-17 of bits 0-17 encoded in a SPTE).
In addition to the above, commit 56871d444b ("KVM: x86: fix overlap between SPTE_MMIO_MASK and generation")
has changed the SPTE bit range assigned to encode the generation number and
the total number of bits encoded but did not update them in the comment
attached to their defines, nor in the KVM MMU doc.
Let's do it here, too, since it is too trivial thing to warrant a separate
commit.

GPIO_ACTIVE_x flags are not correct in the context of interrupt flags.
These are simple defines so they could be used in DTS but they will not
have the same meaning:
1. GPIO_ACTIVE_HIGH = 0 = IRQ_TYPE_NONE
2. GPIO_ACTIVE_LOW = 1 = IRQ_TYPE_EDGE_RISING
Correct the interrupt flags, assuming the author of the code wanted same

ACTIVE_LOW => IRQ_TYPE_LEVEL_LOW

From Daniel's cover letter:
IBM Power9 processors can speculatively operate on data in the L1 cache
before it has been completely validated, via a way-prediction mechanism. It
is not possible for an attacker to determine the contents of impermissible
memory using this method, since these systems implement a combination of
hardware and software security measures to prevent scenarios where
protected data could be leaked.
However these measures don't address the scenario where an attacker induces
the operating system to speculatively execute instructions using data that
the attacker controls. This can be used for example to speculatively bypass
"kernel user access prevention" techniques, as discovered by Anthony
Steinhauser of Google's Safeside Project. This is not an attack by itself,
but there is a possibility it could be used in conjunction with
side-channels or other weaknesses in the privileged code to construct an
attack.
This issue can be mitigated by flushing the L1 cache between privilege
boundaries of concern.
This patch series flushes the L1 cache on kernel entry (patch 2) and after the
kernel performs any user accesses (patch 3). It also adds a self-test and
performs some related cleanups.

The RaspberryPi4 has both a WiFi chip and HDMI outputs capable of doing
4k. Unfortunately, the 1440p resolution at 60Hz has a TMDS rate on the
HDMI cable right in the middle of the first Wifi channel.
Add a property to our HDMI controller, that could be reused by other
similar HDMI controllers, to allow the OS to take whatever measure is
necessary to avoid that crosstalk.

fast_second_level_miss handler for the TLBTEMP area has an assumption
that page table directory entry for the TLBTEMP address range is 0. For
it to be true the TLBTEMP area must be aligned to 4MB boundary and not
share its 4MB region with anything that may use a page table. This is
not true currently: TLBTEMP shares space with vmalloc space which
results in the following kinds of runtime errors when
fast_second_level_miss loads page table directory entry for the vmalloc
space instead of fixing up the TLBTEMP area:

[robh: Add "fsl,imx25-flexcan" as fallback]
Signed-off-by: Rob Herring <robh@kernel.org>
As both the i.MX35 and i.MX53 flexcan IP cores are compatible to the i.MX25,
they are listed as:
compatible = "fsl,imx35-flexcan", "fsl,imx25-flexcan";
and:
compatible = "fsl,imx53-flexcan", "fsl,imx25-flexcan";
in the SoC device trees.
This patch fixes the following errors, which shows up during a dtbs_check:
arch/arm/boot/dts/imx53-ard.dt.yaml: can@53fc8000: compatible: 'oneOf' conditional failed, one must be fixed:

Fast commit feature has flags in the file system as well in JBD2. The
meaning of fast commit feature flags can get confusing. Update docs
and code to add more documentation about it.

Current release - bugs in new features:
- can: isotp: isotp_rcv_cf(): enable RX timeout handling in
listen-only mode
Previous release - regressions:
- mac80211:
- don't require VHT elements for HE on 2.4 GHz
- fix regression where EAPOL frames were sent in plaintext
- netfilter:
- ipset: Update byte and packet counters regardless of whether
they match
- ip_tunnel: fix over-mtu packet send by allowing fragmenting even
if inner packet has IP_DF (don't fragment) set in its header
(when TUNNEL_DONT_FRAGMENT flag is not set on the tunnel dev)
- net: fec: fix MDIO probing for some FEC hardware blocks
- ip6_tunnel: set inner ipproto before ip6_tnl_encap to un-break
gso support
- sctp: Fix COMM_LOST/CANT_STR_ASSOC err reporting on big-endian
platforms, sparse-related fix used the wrong integer size
Previous release - always broken:
- netfilter: use actual socket sk rather than skb sk when routing
harder
- r8169: work around short packet hw bug on RTL8125 by padding frames
- net: ethernet: ti: cpsw: disable PTPv1 hw timestamping
advertisement, the hardware does not support it
- chelsio/chtls: fix always leaking ctrl_skb and another leak caused

- flexcan_remove(): disable wakeup completely
- can: fix packet echo functionality:
- peak_canfd: fix echo management when loopback is on
- make sure skbs are not freed in IRQ context in case they need
to be dropped
- always clone the skbs to make sure they have a reference on
the socket, and prevent it from disappearing
- fix real payload length return value for RTR frames
- can: j1939: return failure on bind if netdev is down, rather than

Here's some small fixes for 5.10-rc2 and a big driver removal.
The fixes are for some reported issues in the interconnect and coresight
drivers, nothing major.
The "big" driver removal is the MIC drivers have been asked to be
removed as the hardware never shipped and Intel no longer wants to
maintain something that no one can use. This is welcomed by many as the
DMA usage of these drivers was "interesting" and the security people
were starting to question some issues that were starting to be found in
the codebase.
Note, one of the subsystems for this driver, the "VOP" code, will
probably come back in future kernel versions as it was looking to
potentially solve some PCIe virtualization issues that a number of other
vendors were wanting to solve. But as-is, this codebase didn't work for
anyone else so no actual functionality is being removed.
All of these have been in linux-next with no reported issues.

Here is one tiny debugfs change to fix up an API where the last user was
successfully fixed up in 5.10-rc1 (so it couldn't be merged earlier),
and a much larger Documentation/ABI/ update to the files so they can be
automatically parsed by our tools.
The Documentation/ABI/ updates are just formatting issues, small ones to

unampped events.
These events are mapped within INTA in contrast to other K3 devices where
the events with similar function was originating from the UDMAP or ringacc.
The ti,unmapped-event-sources should contain phandle array to the devices
in the system (typically DMA controllers) from where the unmapped events
originate.

Both adp8860 and adp8870 define some extensions to the
backlight class. This causes warnings:
Warning: /sys/class/backlight/<backlight>/ambient_light_level is defined 2 times: /sys/class/backlight/<backlight>/ambient_light_level:8 /sys/class/backlight/<backlight>/ambient_light_level:30
Warning: /sys/class/backlight/<backlight>/ambient_light_zone is defined 2 times: /sys/class/backlight/<backlight>/ambient_light_zone:18 /sys/class/backlight/<backlight>/ambient_light_zone:40
As ABI definitions shouldn't be duplicated.
Unfortunately, the ABI is dependent on the specific device
features. As such, ambient_light_level range is somewhat
different among the supported devices.
The ambient_light_zone is even worse: the meanings of each
preset are different, and there's no ABI to retrieve
the supported types nor their meanins. Unfortunately,
it is too late to fix it without causing regressions,
as this has been used since Kernel v2.6.35.
Rewrite those ABI documentation using the current documentation
as a reference, and double-checking at the datasheets:
https://www.analog.com/media/en/technical-documentation/data-sheets/ADP8870.pdfhttps://www.analog.com/media/en/technical-documentation/data-sheets/ADP8860.pdf

drivers.

Now that the stable ABI files are compatible with ReST,
parse them without converting complex descriptions as literal
blocks nor escaping special characters.
Please notice that escaping special characters will probably
be needed at descriptions, at least for the asterisk character.

On Cortex-A77 r0p0 and r1p0, a sequence of a non-cacheable or device load
and a store exclusive or PAR_EL1 read can cause a deadlock.
The workaround requires a DMB SY before and after a PAR_EL1 register
read. In addition, it's possible an interrupt (doing a device read) or
KVM guest exit could be taken between the DMB and PAR read, so we
also need a DMB before returning from interrupt and before returning to
a guest.
A deadlock is still possible with the workaround as KVM guests must also
have the workaround. IOW, a malicious guest can deadlock an affected
systems.
This workaround also depends on a firmware counterpart to enable the h/w
to insert DMB SY after load and store exclusive instructions. See the
errata document SDEN-1152370 v10 [1] for more information.

On exception entry, the kernel explicitly resets the PSTATE.TCO (tag
check override) so that any kernel memory accesses will be checked (the
bit is restored on exception return). This has the side-effect that the
uaccess routines will not honour the PSTATE.TCO that may have been set
by the user prior to a syscall.
There is no issue in practice since PSTATE.TCO is expected to be used
only for brief periods in specific routines (e.g. garbage collection).
To control the tag checking mode of the uaccess routines, the user will
have to invoke a corresponding prctl() call.
Document the kernel behaviour w.r.t. PSTATE.TCO accordingly.

parse the entire file without passing arguments to kernel-doc.
This should place everything altogether.
For amdgpu_ras.c, however, we need to remove the kernel-doc

Pull SafeSetID updates from Micah Morton:
"The changes are mostly contained to within the SafeSetID LSM, with the
exception of a few 1-line changes to change some ns_capable() calls to
ns_capable_setid() -- causing a flag (CAP_OPT_INSETID) to be set that
is examined by SafeSetID code and nothing else in the kernel.
The changes to SafeSetID internally allow for setting up GID
transition security policies, as already existed for UIDs"

SoC changes, a substantial part of this is cleanup of some of the older
platforms that used to have a bunch of board files. In particular:
- Removal of non-DT i.MX platforms that haven't seen activity in years,
it's time to remove them.
- A bunch of cleanup and removal of platform data for TI/OMAP platforms,
moving over to genpd for power/reset control (yay!)
- Major cleanup of Samsung S3C24xx and S3C64xx platforms, moving them
closer to multiplatform support (not quite there yet, but getting
close).
THere are a few other changes too, smaller fixlets, etc. For new
platform support, the primary ones re:
- New SoC: Hisilicon SD5203, ARM926EJ-S platform.
- Cpufreq support for i.MX7ULP

Cross-tree/merge window issues:
- rtl8150: don't incorrectly assign random MAC addresses; fix late
in the 5.9 cycle started depending on a return code from
a function which changed with the 5.10 PR from the usb subsystem
Current release - regressions:
- Revert "virtio-net: ethtool configurable RXCSUM", it was causing
crashes at probe when control vq was not negotiated/available
Previous releases - regressions:
- ixgbe: fix probing of multi-port 10 Gigabit Intel NICs with an MDIO
bus, only first device would be probed correctly
- nexthop: Fix performance regression in nexthop deletion by
effectively switching from recently added synchronize_rcu()
to synchronize_rcu_expedited()
- netsec: ignore 'phy-mode' device property on ACPI systems;
the property is not populated correctly by the firmware,
but firmware configures the PHY so just keep boot settings
Previous releases - always broken:
- tcp: fix to update snd_wl1 in bulk receiver fast path, addressing
bulk transfers getting "stuck"
- icmp: randomize the global rate limiter to prevent attackers from
getting useful signal
- r8169: fix operation under forced interrupt threading, make the
driver always use hard irqs, even on RT, given the handler is
light and only wants to schedule napi (and do so through
a _irqoff() variant, preferably)
- bpf: Enforce pointer id generation for all may-be-null register
type to avoid pointers erroneously getting marked as null-checked
- tipc: re-configure queue limit for broadcast link
- net/sched: act_tunnel_key: fix OOB write in case of IPv6 ERSPAN
tunnels
- fix various issues in chelsio inline tls driver
Misc:
- bpf: improve just-added bpf_redirect_neigh() helper api to support
supplying nexthop by the caller - in case BPF program has already
done a lookup we can avoid doing another one
- remove unnecessary break statements
- make MCTCP not select IPV6, but rather depend on it

crashes at probe when control vq was not negotiated/available
Previous release regressions:
- ixgbe: fix probing of multi-port 10 Gigabit Intel NICs with an MDIO
bus, only first device would be probed correctly
- nexthop: Fix performance regression in nexthop deletion by
effectively switching from recently added synchronize_rcu() to
synchronize_rcu_expedited()
- netsec: ignore 'phy-mode' device property on ACPI systems; the
property is not populated correctly by the firmware, but firmware
configures the PHY so just keep boot settings
Previous releases - always broken:
- tcp: fix to update snd_wl1 in bulk receiver fast path, addressing
bulk transfers getting "stuck"
- icmp: randomize the global rate limiter to prevent attackers from
getting useful signal
- r8169: fix operation under forced interrupt threading, make the
driver always use hard irqs, even on RT, given the handler is light
and only wants to schedule napi (and do so through a _irqoff()
variant, preferably)
- bpf: Enforce pointer id generation for all may-be-null register
type to avoid pointers erroneously getting marked as null-checked
- tipc: re-configure queue limit for broadcast link
- net/sched: act_tunnel_key: fix OOB write in case of IPv6 ERSPAN
tunnels
- fix various issues in chelsio inline tls driver
Misc:
- bpf: improve just-added bpf_redirect_neigh() helper api to support
supplying nexthop by the caller - in case BPF program has already
done a lookup we can avoid doing another one
- remove unnecessary break statements
- make MCTCP not select IPV6, but rather depend on it"

- New page table code for both hypervisor and guest stage-2
- Introduction of a new EL2-private host context
- Allow EL2 to have its own private per-CPU variables
- Support of PMU event filtering
- Complete rework of the Spectre mitigation
PPC:
- Fix for running nested guests with in-kernel IRQ chip
- Fix race condition causing occasional host hard lockup
- Minor cleanups and bugfixes
x86:
- allow trapping unknown MSRs to userspace
- allow userspace to force #GP on specific MSRs
- INVPCID support on AMD
- nested AMD cleanup, on demand allocation of nested SVM state
- hide PV MSRs and hypercalls for features not enabled in CPUID
- new test for MSR_IA32_TSC writes from host and guest
- cleanups: MMU, CPUID, shared MSRs
- LAPIC latency optimizations ad bugfixes
For x86, also included in this pull request is a new alternative and
(in the future) more scalable implementation of extended page tables
that does not need a reverse map from guest physical addresses to
host physical addresses. For now it is disabled by default because
it is still lacking a few of the existing MMU's bells and whistles.
However it is a very solid piece of work and it is already available
for people to hammer on it.

This introduces support for the Mediatek MT9182 SCP and controlling the
Cortex R5F processors found in TI K3 platforms. It clones the
longstanding debugfs interface for controlling crash handling to sysfs.
Lastly it solves a bug where after a warm reset of Qualcomm platforms
the modem would crash upon first boot.

of various clk driver updates. The biggest driver updates in terms of lines of
code is the Allwinner driver, closely followed by the Qualcomm and Mediatek
drivers. All of those hit high because we add so many lines of clk data. Coming
in fourth place is i.MX which also adds a bunch of clk data. This accounts for
the new driver additions this time around.
Otherwise the patches are lots of little cleanups and fixes for various clk
drivers that have baked in linux-next for a while. I suppose one highlight or
theme is that more clk drivers are being updated to work as modules, which is
interesting to see such critical SoC infrastructure work as a loadable module.
New Drivers:
- Support qcom SM8150/SM8250 video and display clks
- Support Mediatek MT8167 clks
- Add clock for CRC block found on vf610 SoCs
- Add support for the Renesas R-Car V3U (R8A779A0) SoC
- Add support for the VSP for Resizing clock on Renesas RZ/G1H
- Support Allwinner A100 SoC clks
Removed Drivers:
- Remove i.MX21 clock driver, as i.MX21 platform support is being dropped
Updates:
- Change how qcom's display port clks work
- Small non-critical fixes for TI clk driver
- Remove various unused variables in clk drivers
- Allow Rockchip clk driver to be a module
- Remove most __clk_lookup() calls in Samsung drivers (yay!)
- Support building i.MX ARMv8 platforms clock driver as module
- Some kerneldoc fixes here and there
- A couple of minor i.MX clk data corrections
- Update audio clock inverter and fdiv2 flag on Amlogic g12
- Make amlogic clk drivers configurable in Kconfig
- Fix Renesas VSP clock names to match corrected hardware documentation
- Sigma-delta modulation on Allwinner R40
- Various fixes for at91 clk driver
- Use semicolons instead of commas in some places

where mmap'ed pages that are being changed in parallel with a

failure that could cause journal replays to fail. Also notable is
Ritesh's buffered write optimization which can result in significant
improvements on parallel write workloads. (The kernel test robot

Besides that, we have the usual miscellaneous cleanups and bug fixes.

KVM unconditionally provides PV features to the guest, regardless of the
configured CPUID. An unwitting guest that doesn't check
KVM_CPUID_FEATURES before use could access paravirt features that
userspace did not intend to provide. Fix this by checking the guest's
CPUID before performing any paravirtual operations.
Introduce a capability, KVM_CAP_ENFORCE_PV_FEATURE_CPUID, to gate the
aforementioned enforcement. Migrating a VM from a host w/o this patch to
a host with this patch could silently change the ABI exposed to the
guest, warranting that we default to the old behavior and opt-in for
the new one.

Allowing userspace to intercept reads to x2APIC MSRs when APICV is
fully enabled for the guest simply can't work. But more in general,
the LAPIC could be set to in-kernel after the MSR filter is setup
and allowing accesses by userspace would be very confusing.
We could in principle allow userspace to intercept reads and writes to TPR,
and writes to EOI and SELF_IPI, but while that could be made it work, it
would still be silly.

Rework the resetting of the MSR bitmap for x2APIC MSRs to ignore userspace
filtering. Allowing userspace to intercept reads to x2APIC MSRs when
APICV is fully enabled for the guest simply can't work; the LAPIC and thus
virtual APIC is in-kernel and cannot be directly accessed by userspace.
To keep things simple we will in fact forbid intercepting x2APIC MSRs
altogether, independent of the default_allow setting.

Persistent grants feature provides high scalability. On some small
systems, however, it could incur data copy overheads[1] and thus it is
required to be disabled. It can be disabled from blkback side using a
module parameter, 'feature_persistent'. But, it is impossible from
blkfront side. For the reason, this commit adds a blkfront module
parameter for disabling of the feature.

Since commit bbc4d71d63 ("net: phy: realtek: fix rtl8211e rx/tx
delay config"), the Realtek PHY driver will override any TX/RX delay
set by hardware straps if the phy-mode device property does not match.
This is causing problems on SynQuacer based platforms (the only SoC
that incorporates the netsec hardware), since many were built with
this Realtek PHY, and shipped with firmware that defines the phy-mode
as 'rgmii', even though the PHY is configured for TX and RX delay using
pull-ups.
From the driver's perspective, we should not make any assumptions in
the general case that the PHY hardware does not require any initial
configuration. However, the situation is slightly different for ACPI
boot, since it implies rich firmware with AML abstractions to handle
hardware details that are not exposed to the OS. So in the ACPI case,
it is reasonable to assume that the PHY comes up in the right mode,
regardless of whether the mode is set by straps, by boot time firmware
or by AML executed by the ACPI interpreter.
So let's ignore the 'phy-mode' device property when probing the netsec
driver in ACPI mode, and hardcode the mode to PHY_INTERFACE_MODE_NA,
which should work with any PHY provided that it is configured by the
time the driver attaches to it. While at it, document that omitting
the mode is permitted for DT probing as well, by setting the phy-mode
DT property to the empty string.

KVM/arm64 updates for Linux 5.10
- New page table code for both hypervisor and guest stage-2
- Introduction of a new EL2-private host context
- Allow EL2 to have its own private per-CPU variables
- Support of PMU event filtering
- Complete rework of the Spectre mitigation
In case rogue guests are sending events at high frequency it might
happen that xen_evtchn_do_upcall() won't stop processing events in
dom0. As this is done in irq handling a crash might be the result.
In order to avoid that, delay further inter-domain events after some
time in xen_evtchn_do_upcall() by forcing eoi processing into a
worker on the same cpu, thus inhibiting new events coming in.
The time after which eoi processing is to be delayed is configurable
via a new module parameter "event_loop_timeout" which specifies the
maximum event loop time in jiffies (default: 2, the value was chosen
after some tests showing that a value of 2 was the lowest with an
only slight drop of dom0 network throughput while multiple guests
performed an event storm).
How long eoi processing will be delayed can be specified via another
parameter "event_eoi_delay" (again in jiffies, default 10, again the
value was chosen after testing with different delay values).
This is part of XSA-332.

- New feature: Widen inode timestamps and quota grace expiration
timestamps to support dates through the year 2486.
- New feature: storing inode btree counts in the AGI to speed up certain
mount time per-AG block reservation operatoins and add a little more
metadata redundancy.
For the second round of new code for 5.10:
- Deprecate the V4 filesystem format, some disused mount options, and some
legacy sysctl knobs now that we can support dates into the 25th century.
Note that removal of V4 support will not happen until the early 2030s.
- Fix some probles with inode realtime flag propagation.
- Fix some buffer handling issues when growing a rt filesystem.
- Fix a problem where a BMAP_REMAP unmap call would free rt extents even
though the purpose of BMAP_REMAP is to avoid freeing the blocks.
- Strengthen the dabtree online scrubber to check hash values on child
dabtree blocks.
- Actually log new intent items created as part of recovering log intent
items.
- Fix a bug where quotas weren't attached to an inode undergoing bmap
intent item recovery.
- Fix a buffer overrun problem with specially crafted log buffer
headers.
- Various cleanups to type usage and slightly inaccurate comments.
- More cleanups to the xattr, log, and quota code.
- Don't run the (slower) shared-rmap operations on attr fork mappings.
- Fix a bug where we failed to check the LSN of finobt blocks during

- Clean up the ugly nested transaction mess that log recovery uses to

- Fix a UAF bug in bmap intent item recovery where we failed to maintain
our reference to the incore inode if the bmap operation needed to
relog itself to continue.
- Rearrange the defer ops mechanism to finish newly created subtasks
of a parent task before moving on to the next parent task.
- Automatically relog intent items in deferred ops chains if doing so
would help us avoid pinning the log tail. This will help fix some
log scaling problems now and will facilitate atomic file updates later.

Merge tag 'xfs-5.10-merge-5' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux
Pull more xfs updates from Darrick Wong:
"The second large pile of new stuff for 5.10, with changes even more
monumental than last week!
We are formally announcing the deprecation of the V4 filesystem format
in 2030. All users must upgrade to the V5 format, which contains
design improvements that greatly strengthen metadata validation,
supports reflink and online fsck, and is the intended vehicle for
handling timestamps past 2038. We're also deprecating the old Irix
behavioral tweaks in September 2025.
Coming along for the ride are two design changes to the deferred
metadata ops subsystem. One of the improvements is to retain correct
logical ordering of tasks and subtasks, which is a more logical design
for upper layers of XFS and will become necessary when we add atomic
file range swaps and commits. The second improvement to deferred ops
improves the scalability of the log by helping the log tail to move
forward during long-running operations. This reduces log contention
when there are a large number of threads trying to run transactions.
In addition to that, this fixes numerous small bugs in log recovery;
refactors logical intent log item recovery to remove the last
remaining place in XFS where we could have nested transactions; fixes
a couple of ways that intent log item recovery could fail in ways that
wouldn't have happened in the regular commit paths; fixes a deadlock
vector in the GETFSMAP implementation (which improves its performance
by 20%); and fixes serious bugs in the realtime growfs, fallocate, and
bitmap handling code.
Summary:
- Deprecate the V4 filesystem format, some disused mount options, and
some legacy sysctl knobs now that we can support dates into the
25th century. Note that removal of V4 support will not happen until
the early 2030s.
- Fix some probles with inode realtime flag propagation.
- Fix some buffer handling issues when growing a rt filesystem.

This pull request introduces the following changes to zonefs:
* Add the "explicit-open" mount option to automatically issue a
REQ_OP_ZONE_OPEN command to the device whenever a sequential zone file
is open for writing for the first time. This avoids "insufficient zone
resources" errors for write operations on some drives with limited
zone resources or on ZNS drives with a limited number of active zones.

This addresses the concern Kunit would not work correctly during
late init phase.

Keyu Man reported that the ICMP rate limiter could be used
by attackers to get useful signal. Details will be provided
in an upcoming academic publication.
Our solution is to add some noise, so that the attackers
no longer can get help from the predictable token bucket limiter.

In this round, we've added new features such as zone capacity for ZNS and
a new GC policy, ATGC, along with in-memory segment management. In addition,
we could improve the decompression speed significantly by changing virtual
mapping method. Even though we've fixed lots of small bugs in compression
support, I feel that it becomes more stable so that I could give it a try in
production.
Enhancement:
- suport zone capacity in NVMe Zoned Namespace devices
- introduce in-memory current segment management
- add standart casefolding support
- support age threshold based garbage collection
- improve decompression speed by changing virtual mapping method
Bug fix:
- fix condition checks in some ioctl() such as compression, move_range, etc
- fix 32/64bits support in data structures
- fix memory allocation in zstd decompress
- add some boundary checks to avoid kernel panic on corrupted image
- fix disallowing compression for non-empty file
- fix slab leakage of compressed block writes
In addition, it includes code refactoring for better readability and minor
bug fixes for compression and zoned device support.

Pull documentation updates from Mauro Carvalho Chehab:
"A series of patches addressing warnings produced by make htmldocs.
This includes:
- kernel-doc markup fixes
- ReST fixes
- Updates at the build system in order to support newer versions of
the docs build toolchain (Sphinx)
After this series, the number of html build warnings should reduce
significantly, and building with Sphinx 3.1 or later should now be
supported (although it is still recommended to use Sphinx 2.4.4).
As agreed with Jon, I should be sending you a late pull request by the
end of the merge window addressing remaining issues with docs build,
as there are a number of warning fixes that depends on pull requests
that should be happening along the merge window.
The end goal is to have a clean htmldocs build on Kernel 5.10.
PS. It should be noticed that Sphinx 3.0 is not currently supported,
as it lacks support for C domain namespaces. Such feature, needed in
order to document uAPI system calls with Sphinx 3.x, was added only on
Sphinx 3.1"

Patch series "add fault injection to user memory access", v3.
The goal of this series is to improve testing of fault-tolerance in usages
of user memory access functions, by adding support for fault injection.
syzkaller/syzbot are using the existing fault injection modes and will use
this particular feature also.
The first patch adds failure injection capability for usercopy functions.
The second changes usercopy functions to use this new failure capability
(copy_from_user, ...). The third patch adds get/put/clear_user failures
to x86.
This patch (of 3):
Add a failure injection capability to improve testing of fault-tolerance
in usages of user memory access functions.
Add CONFIG_FAULT_INJECTION_USERCOPY to enable faults in usercopy
functions. The should_fail_usercopy function is to be called by these
functions (copy_from_user, get_user, ...) in order to fail or not.

In order to use multi-index entries for huge pages in the page cache, we
need to be able to split a multi-index entry (eg if a file is truncated in
the middle of a huge page entry). This version does not support splitting
more than one level of the tree at a time. This is an acceptable
limitation for the page cache as we do not expect to support order-12
pages in the near future.

From Maor Gottlieb says:
====================
This series extends __sg_alloc_table_from_pages to allow chaining of new
pages to an already initialized SG table.
This allows for drivers to utilize the optimization of merging contiguous
pages without a need to pre allocate all the pages and hold them in a very
large temporary buffer prior to the call to SG table initialization.
The last patch changes the Infiniband core to use the new API. It removes
duplicate functionality from the code and benefits from the optimization
of allocating dynamic SG table from pages.
In huge pages system of 2MB page size, without this change, the SG table
would contain x512 SG entries.
====================
* branch 'dynamic_sg':
RDMA/umem: Move to allocate SG table from pages
lib/scatterlist: Add support in dynamic allocation of SG table from pages
tools/testing/scatterlist: Show errors in human readable form
tools/testing/scatterlist: Rejuvenate bit-rotten test
There's a missing new line for a literal block:

Signed-off-by: Mauro Carvalho Chehab <mchehab+huawei@kernel.org>
Add redirect_neigh() BPF packet redirect helper, allowing to limit stack
traversal in common container configs and improving TCP back-pressure.
Daniel reports ~10Gbps => ~15Gbps single stream TCP performance gain.
Expand netlink policy support and improve policy export to user space.
(Ge)netlink core performs request validation according to declared
policies. Expand the expressiveness of those policies (min/max length
and bitmasks). Allow dumping policies for particular commands.
This is used for feature discovery by user space (instead of kernel
version parsing or trial and error).
Support IGMPv3/MLDv2 multicast listener discovery protocols in bridge.
Allow more than 255 IPv4 multicast interfaces.
Add support for Type of Service (ToS) reflection in SYN/SYN-ACK
packets of TCPv6.
In Multi-patch TCP (MPTCP) support concurrent transmission of data
on multiple subflows in a load balancing scenario. Enhance advertising
addresses via the RM_ADDR/ADD_ADDR options.
Support SMC-Dv2 version of SMC, which enables multi-subnet deployments.
Allow more calls to same peer in RxRPC.
Support two new Controller Area Network (CAN) protocols -
CAN-FD and ISO 15765-2:2016.
Add xfrm/IPsec compat layer, solving the 32bit user space on 64bit
kernel problem.
Add TC actions for implementing MPLS L2 VPNs.
Improve nexthop code - e.g. handle various corner cases when nexthop
objects are removed from groups better, skip unnecessary notifications
and make it easier to offload nexthops into HW by converting
to a blocking notifier.
Support adding and consuming TCP header options by BPF programs,
opening the doors for easy experimental and deployment-specific
TCP option use.
Reorganize TCP congestion control (CC) initialization to simplify life
of TCP CC implemented in BPF.
Add support for shipping BPF programs with the kernel and loading them
early on boot via the User Mode Driver mechanism, hence reusing all the
user space infra we have.
Support sleepable BPF programs, initially targeting LSM and tracing.
Add bpf_d_path() helper for returning full path for given 'struct path'.
Make bpf_tail_call compatible with bpf-to-bpf calls.
Allow BPF programs to call map_update_elem on sockmaps.
Add BPF Type Format (BTF) support for type and enum discovery, as
well as support for using BTF within the kernel itself (current use
is for pretty printing structures).
Support listing and getting information about bpf_links via the bpf
syscall.
Enhance kernel interfaces around NIC firmware update. Allow specifying
overwrite mask to control if settings etc. are reset during update;
report expected max time operation may take to users; support firmware
activation without machine reboot incl. limits of how much impact
reset may have (e.g. dropping link or not).
Extend ethtool configuration interface to report IEEE-standard
counters, to limit the need for per-vendor logic in user space.
Adopt or extend devlink use for debug, monitoring, fw update
in many drivers (dsa loop, ice, ionic, sja1105, qed, mlxsw,
mv88e6xxx, dpaa2-eth).
In mlxsw expose critical and emergency SFP module temperature alarms.
Refactor port buffer handling to make the defaults more suitable and
support setting these values explicitly via the DCBNL interface.
Add XDP support for Intel's igb driver.
Support offloading TC flower classification and filtering rules to
mscc_ocelot switches.
Add PTP support for Marvell Octeontx2 and PP2.2 hardware, as well as
fixed interval period pulse generator and one-step timestamping in
dpaa-eth.
Add support for various auth offloads in WiFi APs, e.g. SAE (WPA3)
offload.
Add Lynx PHY/PCS MDIO module, and convert various drivers which have
this HW to use it. Convert mvpp2 to split PCS.
Support Marvell Prestera 98DX3255 24-port switch ASICs, as well as
7-port Mediatek MT7531 IP.
Add initial support for QCA6390 and IPQ6018 in ath11k WiFi driver,
and wcn3680 support in wcn36xx.
Improve performance for packets which don't require much offloads
on recent Mellanox NICs by 20% by making multiple packets share
a descriptor entry.
Move chelsio inline crypto drivers (for TLS and IPsec) from the crypto
subtree to drivers/net. Move MDIO drivers out of the phy directory.
Clean up a lot of W=1 warnings, reportedly the actively developed
subsections of networking drivers should now build W=1 warning free.
Make sure drivers don't use in_interrupt() to dynamically adapt their
code. Convert tasklets to use new tasklet_setup API (sadly this
conversion is not yet complete).

syscall.
- Enhance kernel interfaces around NIC firmware update. Allow
specifying overwrite mask to control if settings etc. are reset
during update; report expected max time operation may take to users;
support firmware activation without machine reboot incl. limits of
how much impact reset may have (e.g. dropping link or not).
- Extend ethtool configuration interface to report IEEE-standard
counters, to limit the need for per-vendor logic in user space.
- Adopt or extend devlink use for debug, monitoring, fw update in many
drivers (dsa loop, ice, ionic, sja1105, qed, mlxsw, mv88e6xxx,
dpaa2-eth).
- In mlxsw expose critical and emergency SFP module temperature alarms.
Refactor port buffer handling to make the defaults more suitable and
support setting these values explicitly via the DCBNL interface.
- Add XDP support for Intel's igb driver.
- Support offloading TC flower classification and filtering rules to
mscc_ocelot switches.
- Add PTP support for Marvell Octeontx2 and PP2.2 hardware, as well as
fixed interval period pulse generator and one-step timestamping in
dpaa-eth.
- Add support for various auth offloads in WiFi APs, e.g. SAE (WPA3)
offload.
- Add Lynx PHY/PCS MDIO module, and convert various drivers which have
this HW to use it. Convert mvpp2 to split PCS.
- Support Marvell Prestera 98DX3255 24-port switch ASICs, as well as
7-port Mediatek MT7531 IP.
- Add initial support for QCA6390 and IPQ6018 in ath11k WiFi driver,
and wcn3680 support in wcn36xx.
- Improve performance for packets which don't require much offloads on
recent Mellanox NICs by 20% by making multiple packets share a
descriptor entry.
- Move chelsio inline crypto drivers (for TLS and IPsec) from the
crypto subtree to drivers/net. Move MDIO drivers out of the phy
directory.
- Clean up a lot of W=1 warnings, reportedly the actively developed
subsections of networking drivers should now build W=1 warning free.
- Make sure drivers don't use in_interrupt() to dynamically adapt their
code. Convert tasklets to use new tasklet_setup API (sadly this
conversion is not yet complete).

This kselftest update for Linux 5.10-rc1 consists of enhancements to
-- speed up headers_install done during selftest build
-- add generic make nesting support
-- add support to select individual tests:
- Selftests build/install generates run_kselftest.sh script to run
selftests on a target system. Currently the script doesn't have
support for selecting individual tests. Add support for it.
With this enhancement, user can select test collections (or tests)
individually. e.g:
run_kselftest.sh -c seccomp -t timers:posix_timers -t timers:nanosleep
Additionally adds a way to list all known tests with "-l", usage
with "-h", and perform a dry run without running tests with "-n".

The amount of changes is smaller at this round (what a surprise),
but lots of activity is seen. Most of changes are about ASoC
driver development, especially Intel platforms.
Here are some highlights:
General:
* Replace all tasklet usages with other alternatives
* Cleanup of the ASoC error unwinding code
* Fixes for trivial issues caught by static checker
* Spell fixes allover the places
ALSA Core:
* Lockdep fix for control devices
* Fix for potential OSS sequencer mutex stalls
HD-audio and USB-audio:
* SoundBlaster AE-7 support
* Changes in quirk table for the rename handling
* Quirks for HP and ASUS machines, Pioneer DJ DJM-250MK2.
ASoC:
* Lots of updates for Intel SOF and SoundWire enablement
* Replacement of the DSP driver for some older x86 systems;
the new code was written from scratch, better maintenance
expected
* Helpers for parsing auxiluary devices from the device tree
* New support for AllWinner A64, Cirrus Logic CS4234, Mediatek

Pull drm updates from Dave Airlie:
"Not a major amount of change, the i915 trees got split into display
and gt trees to better facilitate higher level review, and there's a
major refactoring of i915 GEM locking to use more core kernel concepts
(like ww-mutexes). msm gets per-process pagetables, older AMD SI cards
get DC support, nouveau got a bump in displayport support with common
code extraction from i915.

The typec_bus.rst asks for documentation of those two
functions, but they don't exist:
./drivers/usb/typec/bus.c:1: warning: 'typec_altmode_unregister_driver' not found
./drivers/usb/typec/bus.c:1: warning: 'typec_altmode_register_driver' not found
Also, they're not declared on bus.c but, instead, at a header
file (typec_altmode.h).
So, add documentation for both functions at the header and
change the kernel-doc markup under typec_bus.rst to point
to the right place.
While here, also place the documentation for both structs
declared on typec_altmode.h at the rst file.

After the build fix patches, it is believed that the output
with Sphinx 3.x won't be a problem. Still, the C domain
support was re-written, and this can have caused hidden
issues.
So, let's keep the warning, changing it to a lighter
warning text.
Signed-off-by: Mauro Carvalho Chehab <mchehab+huawei@kernel.org>
Sphinx C parser for the C domain is now more pedantic when
trying to identify the function types. That prevents scope
macros to be used as type defines.
Yet, since 3.0.2, it is possible to provide it a list of
such macros. Add them, in order to solve several Sphinx 3.x
warnings.
