We have a production-level laptop (Lenovo Yoga C630) which is exhibiting
a rather horrific bug. When I2C HID devices are being scanned for at
boot-time the QCom Geni based I2C (Serial Engine) attempts to use DMA.
When it does, the laptop reboots and the user never sees the OS.
Attempts are being made to debug the reason for the spontaneous reboot.
No luck so far, hence the requirement for this hot-fix. This workaround

Pull kernel lockdown mode from James Morris:
"This is the latest iteration of the kernel lockdown patchset, from
Matthew Garrett, David Howells and others.
From the original description:
This patchset introduces an optional kernel lockdown feature,
intended to strengthen the boundary between UID 0 and the kernel.
When enabled, various pieces of kernel functionality are restricted.
Applications that rely on low-level access to either hardware or the
kernel may cease working as a result - therefore this should not be
enabled without appropriate evaluation beforehand.
The majority of mainstream distributions have been carrying variants
of this patchset for many years now, so there's value in providing a
doesn't meet every distribution requirement, but gets us much closer
to not requiring external patches.
There are two major changes since this was last proposed for mainline:
- Separating lockdown from EFI secure boot. Background discussion is
covered here: https://lwn.net/Articles/751061/
- Implementation as an LSM, with a default stackable lockdown LSM
module. This allows the lockdown feature to be policy-driven,
rather than encoding an implicit policy within the mechanism.
The new locked_down LSM hook is provided to allow LSMs to make a
policy decision around whether kernel functionality that would allow
tampering with or examining the runtime state of the kernel should be
permitted.
The included lockdown LSM provides an implementation with a simple
policy intended for general purpose use. This policy provides a coarse
level of granularity, controllable via the kernel command line:
lockdown={integrity|confidentiality}
Enable the kernel lockdown feature. If set to integrity, kernel features
that allow userland to modify the running kernel are disabled. If set to
confidentiality, kernel features that allow userland to extract
confidential information from the kernel are also disabled.
This may also be controlled via /sys/kernel/security/lockdown and
overriden by kernel configuration.
New or existing LSMs may implement finer-grained controls of the
lockdown features. Refer to the lockdown_reason documentation in
include/linux/security.h for details.
The lockdown feature has had signficant design feedback and review
across many subsystems. This code has been in linux-next for some
weeks, with a few fixes applied along the way.
Stephen Rothwell noted that commit 9d1f8be5cf ("bpf: Restrict bpf
when kernel lockdown is in confidentiality mode") is missing a

Pull integrity updates from Mimi Zohar:
"The major feature in this time is IMA support for measuring and
appraising appended file signatures. In addition are a couple of bug
fixes and code cleanup to use struct_size().
In addition to the PE/COFF and IMA xattr signatures, the kexec kernel
image may be signed with an appended signature, using the same
scripts/sign-file tool that is used to sign kernel modules.
Similarly, the initramfs may contain an appended signature.
This contained a lot of refactoring of the existing appended signature
verification code, so that IMA could retain the existing framework of
calculating the file hash once, storing it in the IMA measurement list
and extending the TPM, verifying the file's integrity based on a file
hash or signature (eg. xattrs), and adding an audit record containing
the file hash, all based on policy. (The IMA support for appended
signatures patch set was posted and reviewed 11 times.)
The support for appended signature paves the way for adding other
signature verification methods, such as fs-verity, based on a single
system-wide policy. The file hash used for verifying the signature and
the signature, itself, can be included in the IMA measurement list"

It's similar in functionality to the existing virtio-9p solution, but
significantly faster in benchmarks and has better POSIX compliance.
Further permformance improvements can be achieved by sharing the page
cache between host and guest, allowing for faster I/O and reduced
memory use.

Yuchung Cheng and Marek Majkowski independently reported a weird
behavior of TCP_USER_TIMEOUT option when used at connect() time.
When the TCP_USER_TIMEOUT is reached, tcp_write_timeout()
believes the flow should live, and the following condition
in tcp_clamp_rto_to_user_timeout() programs one jiffie timers :
remaining = icsk->icsk_user_timeout - elapsed;
if (remaining <= 0)
return 1; /* user timeout has passed; fire ASAP */
This silly situation ends when the max syn rtx count is reached.
This patch makes sure we honor both TCP_SYNCNT and TCP_USER_TIMEOUT,
avoiding these spurious SYN packets.

At this time, scrubbing clears secpath and bridge netfilter data, but
retains the tc skb extension, after this patch all three get cleared.

There was a bug in the previous logic that attempted to ensure gain cycling
gets inflight above BDP even for small BDPs. This code correctly raised and
lowered target inflight values during the gain cycle. And this code
correctly ensured that cwnd was raised when probing bandwidth. However, it
did not correspondingly ensure that cwnd was *not* raised in this way when
*not* probing for bandwidth. The result was that small-BDP flows that were
always cwnd-bound could go for many cycles with a fixed cwnd, and not probe
or yield bandwidth at all. This meant that multiple small-BDP flows could
fail to converge in their bandwidth allocations.

mlxsw: Various fixes
This patchset includes two small fixes for the mlxsw driver and one
patch which clarifies recently introduced devlink-trap documentation.
Patch #1 clears the port's VLAN filters during port initialization. This
ensures that the drop reason reported to the user is consistent. The
problem is explained in detail in the commit message.
Patch #2 clarifies the description of one of the traps exposed via
devlink-trap.
Patch #3 from Danielle forbids the installation of a tc filter with
multiple mirror actions since this is not supported by the device. The
failure is communicated to the user via extack.

When a port is created, its VLAN filters are not cleared by the
firmware. This causes tagged packets to be later dropped by the ingress
STP filters, which default to DISCARD state.
The above did not matter much until commit b5ce611fd9 ("mlxsw:
spectrum: Add devlink-trap support") where we exposed the drop reason to
users.
Without this patch, the drop reason users will see is not consistent. If
a port is enslaved to a VLAN-aware bridge and a packet with an invalid
VLAN tries to ingress the bridge, it will be dropped due to ingress STP
filter. If the VLAN is later enabled and then disabled, the packet will
be dropped by the ingress VLAN filter despite the above being a
seemingly NOP operation.
Fix this by clearing all the VLAN filters during port initialization.
Adjust the test accordingly.

The SDHCI controller on Tegra186 supports 40-bit addressing, which is
usually enough to address all of system memory. However, if the SDHCI
controller is behind an IOMMU, the address space can go beyond. This
happens on Tegra186 and later where the ARM SMMU has an input address
space of 48 bits. If the DMA API is backed by this ARM SMMU, the top-
down IOVA allocator will cause IOV addresses to be returned that the
SDHCI controller cannot access.
Unfortunately, prior to the introduction of the ->set_dma_mask() host
operation, the SDHCI core would set either a 64-bit DMA mask if the
controller claimed to support 64-bit addressing, or a 32-bit DMA mask
otherwise.
Since the full 64 bits cannot be addressed on Tegra, this had to be
worked around in commit 68481a7e1c ("mmc: tegra: Mark 64 bit dma
broken on Tegra186") by setting the SDHCI_QUIRK2_BROKEN_64_BIT_DMA
quirk, which effectively restricts the DMA mask to 32 bits.
One disadvantage of this is that dma_map_*() APIs will now try to use
the swiotlb to bounce DMA to addresses beyond of the controller's DMA
mask. This in turn caused degraded performance and can lead to
situations where the swiotlb buffer is exhausted, which in turn leads
to DMA transfers to fail.
With the recent introduction of the ->set_dma_mask() host operation,
this can now be properly fixed. For each generation of Tegra, the exact
supported DMA mask can be configured. This kills two birds with one
stone: it avoids the use of bounce buffers because system memory never
exceeds the addressable memory range of the SDHCI controllers on these
devices, and at the same time when an IOMMU is involved, it prevents
IOV addresses from being allocated beyond the addressible range of the
controllers.
Since the DMA mask is now properly handled, the 64-bit DMA quirk can be
removed.

We must not unconditionally set the DMA snoop bit; if the DMA API is
assuming that the device is not DMA coherent, and the device snoops the
CPU caches, the device can see stale cache lines brought in by
speculative prefetch.
This leads to the device seeing stale data, potentially resulting in
corrupted data transfers. Commonly, this results in a descriptor fetch
error such as:

mmc0: error -5 whilst initialising SD card
but can lead to other errors, and potentially direct the SDHCI
controller to read/write data to other memory locations (e.g. if a valid
descriptor is visible to the device in a stale cache line.)
Fix this by ensuring that the DMA snoop bit corresponds with the
behaviour of the DMA API. Since the driver currently only supports DT,
use of_dma_is_coherent(). Note that device_get_dma_attr() can not be
used as that risks re-introducing this bug if/when the driver is
converted to ACPI.

ADMA errors are potentially data corrupting events; although we print
the register state, we do not usefully print the ADMA descriptors.
Worse than that, we print them by referencing their virtual address
which is meaningless when the register state gives us the DMA address
of the failing descriptor.
Print the ADMA descriptors giving their DMA addresses rather than their
virtual addresses, and print them using SDHCI_DUMP() rather than DBG().
We also do not show the correct value of the interrupt status register;
the register dump shows the current value, after we have cleared the
pending interrupts we are going to service. What is more useful is to
print the interrupts that _were_ pending at the time the ADMA error was
encountered. Fix that too.

The Micrel KSZ9031 PHY may fail to establish a link when the Asymmetric
Pause capability is set. This issue is described in a Silicon Errata
(DS80000691D or DS80000692D), which advises to always disable the
capability.
Micrel KSZ9021 has no errata, but has the same issue with Asymmetric Pause.
This patch apply the same workaround as the one for KSZ9031.

Commit 415606588c ("PTP: introduce new versions of IOCTLs",
2019-09-13) introduced new versions of the PTP ioctls which actually
validate that the flags are acceptable values.
As part of this, it cleared the flags value using a bitwise
and+negation, in an attempt to prevent the old ioctl from accidentally
enabling new features.
This is incorrect for a couple of reasons. First, it results in
accidentally preventing previously working flags on the request ioctl.
By clearing the "valid" flags, we now no longer allow setting the
enable, rising edge, or falling edge flags.
Second, if we add new additional flags in the future, they must not be
set by the old ioctl. (Since the flag wasn't checked before, we could
potentially break userspace programs which sent garbage flag data.
The correct way to resolve this is to check for and clear all but the
originally valid flags.
Create defines indicating which flags are correctly checked and
interpreted by the original ioctls. Use these to clear any bits which
will not be correctly interpreted by the original ioctls.
In the future, new flags must be added to the VALID_FLAGS macros, but
*not* to the V1_VALID_FLAGS macros. In this way, new features may be
exposed over the v2 ioctls, but without breaking previous userspace
which happened to not clear the flags value properly. The old ioctl will
continue to behave the same way, while the new ioctl gains the benefit
of using the flags fields.

The regmap stride is set to 1 for regmap describing 8bit registers already.
However, for 16/32/64bit registers, the stride is 2/4/8 respectively. This
is not correct, as the switch protocol supports unaligned register reads
and writes and the KSZ87xx even uses such unaligned register accesses to
read e.g. MIB counter.
This patch fixes MIB counter access on KSZ87xx.

Netfilter fixes for net
The following patchset contains Netfilter fixes for net:
1) Add NFT_CHAIN_POLICY_UNSET to replace hardcoded -1 to
specify that the chain policy is unset. The chain policy
field is actually defined as an 8-bit unsigned integer.
2) Remove always true condition reported by smatch in
chain policy check.
3) Fix element lookup on dynamic sets, from Florian Westphal.
4) Use __u8 in ebtables uapi header, from Masahiro Yamada.
5) Bogus EBUSY when removing flowtable after chain flush,
