commit 08389d888287c3823f80b0216766b71e17f0aba5 upstream.
Add a kconfig knob which allows for unprivileged bpf to be disabled by default.
If set, the knob sets /proc/sys/kernel/unprivileged_bpf_disabled to value of 2.
This still allows a transition of 2 -> {0,1} through an admin. Similarly,
this also still keeps 1 -> {1} behavior intact, so that once set to permanently
disabled, it cannot be undone aside from a reboot.
We've also added extra2 with max of 2 for the procfs handler, so that an admin
still has a chance to toggle between 0 <-> 2.
Either way, as an additional alternative, applications can make use of CAP_BPF
that we added a while ago.

[ Upstream commit 9222ba68c3f4065f6364b99cc641b6b019ef2d42 ]
We've got a bug report about the non-working keyboard on ASUS ZenBook
UX425UA. It seems that the PS/2 device isn't ready immediately at
boot but takes some seconds to get ready. Until now, the only
workaround is to defer the probe, but it's available only when the
driver is a module. However, many distros, including openSUSE as in
the original report, build the PS/2 input drivers into kernel, hence
it won't work easily.
This patch adds the support for the deferred probe for i8042 stuff as
a workaround of the problem above. When the deferred probe mode is
enabled and the device couldn't be probed, it'll be repeated with the
standard deferred probe mechanism.
The deferred probe mode is enabled either via the new option
i8042.probe_defer or via the quirk table entry. As of this patch, the
quirk table contains only ASUS ZenBook UX425UA.
The deferred probe part is based on Fabio's initial work.

[ Upstream commit f8344f7693a25d9025a59d164450b50c6f5aa3c0 ]
TMP461 is almost identical to TMP451 and was actually detected as TMP451
with the existing lm90 driver if its I2C address is 0x4c. Add support
for it to the lm90 driver. At the same time, improve the chip detection
function to at least try to distinguish between TMP451 and TMP461.
As a side effect, this fixes commit 24333ac26d01 ("hwmon: (tmp401) use
smb word operations instead of 2 smb byte operations"). TMP461 does not
support word operations on temperature registers, which causes bad
temperature readings with the tmp401 driver. The lm90 driver does not
perform word operations on temperature registers and thus does not have
this problem.
Support is listed as basic because TMP461 supports a sensor resolution
of 0.0625 degrees C, while the lm90 driver assumes a resolution of 0.125
degrees C. Also, the TMP461 supports negative temperatures with its
default temperature range, which is not the case for similar chips
supported by the lm90 and the tmp401 drivers. Those limitations will be
addressed with follow-up patches.

commit 35bcf519ef4c3ae8f95be0b7e7dd0718f7db1721 from
git@git.assembla.com:cavium/WindRiver.linux.git
Added devlink parameters to configure the source clock of TIM block.
Supported clocks are TENNS, GPIOS, GTI, PTP, SYNC, BTS, EXT_MIO and
EXT_GTI.
To adjust a given clock, the required delta can be written to the
corresponding tim_adjust_<clock> parameter and tim_adjust_timers
parameter can be used to trigger the adjustment. tim_capture_<clock>
parameter can be used to verify the adjusted values for a clock.
Example using tenns clock source:
To adjust a clock source
# devlink dev param set pci/0002:01:00.0 name tim_adjust_tenns \
value "1000" cmode runtime
To trigger adjustment
# devlink dev param set pci/0002:01:00.0 name tim_adjust_timers \
value 1 cmode runtime

commit 9b6164342e981d751e69f5a165dd596ffcdfd6fe upstream.
This document was written a long time ago. Update it.
[1] Drop the version information
The range of the supported GCC versions are always changing. The
current minimal GCC version is 4.9, and commit 1e860048c53e
("gcc-plugins: simplify GCC plugin-dev capability test") removed the
old code accordingly.
We do not need to mention specific version ranges like "all gcc versions
from 4.5 to 6.0" since we forget to update the documentation when we
raise the minimal compiler version.
[2] Drop the C compiler statements
Since commit 77342a02ff6e ("gcc-plugins: drop support for GCC <= 4.7")
the GCC plugin infrastructure only supports g++.
[3] Drop supported architectures
As of v5.11-rc4, the infrastructure supports more architectures;
arm, arm64, mips, powerpc, riscv, s390, um, and x86. (just grep
"select HAVE_GCC_PLUGINS") Again, we miss to update this document when a
new architecture is supported. Let's just say "only some architectures".
[4] Update the apt-get example
We are now discussing to bump the minimal version to GCC 5. The GCC 4.9
support will be removed sooner or later. Change the package example to
gcc-10-plugin-dev while we are here.
[5] Update the build target
Since commit ce2fd53a10c7 ("kbuild: descend into scripts/gcc-plugins/
via scripts/Makefile"), "make gcc-plugins" is not supported.
"make scripts" builds all the enabled plugins, including some other
tools.
[6] Update the steps for adding a new plugin
At first, all CONFIG options for GCC plugins were located in arch/Kconfig.
After commit 45332b1bdfdc ("gcc-plugins: split out Kconfig entries to
scripts/gcc-plugins/Kconfig"), scripts/gcc-plugins/Kconfig became the
central place to collect plugin CONFIG options. In my understanding,
this requirement no longer exists because commit 9f671e58159a ("security:
Create "kernel hardening" config area") moved some of plugin CONFIG
options to another file. Find an appropriate place to add the new CONFIG.
The sub-directory support was never used by anyone, and removed by
commit c17d6179ad5a ("gcc-plugins: remove unused GCC_PLUGIN_SUBDIR").
Remove the useless $(src)/ prefix.

commit 6a631c0432dcccbcf45839016a07c015e335e9ae upstream.
The initial implementation of migrate_disable() for mainline was a
wrapper around preempt_disable(). RT kernels substituted this with
a real migrate disable implementation.
Later on mainline gained true migrate disable support, but the
documentation was not updated.
Update the documentation, remove the claims about migrate_disable()
mapping to preempt_disable() on non-PREEMPT_RT kernels.

[ Upstream commit 7f595d6a6cdc336834552069a2e0a4f6d4756ddf ]
fscrypt currently requires a 512-bit master key when AES-256-XTS is
used, since AES-256-XTS keys are 512-bit and fscrypt requires that the
master key be at least as long any key that will be derived from it.
However, this is overly strict because AES-256-XTS doesn't actually have
a 512-bit security strength, but rather 256-bit. The fact that XTS
takes twice the expected key size is a quirk of the XTS mode. It is
sufficient to use 256 bits of entropy for AES-256-XTS, provided that it
is first properly expanded into a 512-bit key, which HKDF-SHA512 does.
Therefore, relax the check of the master key size to use the security
strength of the derived key rather than the size of the derived key
(except for v1 encryption policies, which don't use HKDF).
Besides making things more flexible for userspace, this is needed in
order for the use of a KDF which only takes a 256-bit key to be
introduced into the fscrypt key hierarchy. This will happen with
hardware-wrapped keys support, as all known hardware which supports that
feature uses an SP800-108 KDF using AES-256-CMAC, so the wrapped keys
are wrapped 256-bit AES keys. Moreover, there is interest in fscrypt
supporting the same type of AES-256-CMAC based KDF in software as an
alternative to HKDF-SHA512. There is no security problem with such
features, so fix the key length check to work properly with them.

commit 40fdea0284bb20814399da0484a658a96c735d90 upstream.
When running as PVH or HVM guest with actual memory < max memory the
hypervisor is using "populate on demand" in order to allow the guest
to balloon down from its maximum memory size. For this to work
correctly the guest must not touch more memory pages than its target
memory size as otherwise the PoD cache will be exhausted and the guest
is crashed as a result of that.
In extreme cases ballooning down might not be finished today before
the init process is started, which can consume lots of memory.
In order to avoid random boot crashes in such cases, add a late init
call to wait for ballooning down having finished for PVH/HVM guests.
Warn on console if initial ballooning fails, panic() after stalling
for more than 3 minutes per default. Add a module parameter for
changing this timeout.

commit b16bef60a9112b1e6daf3afd16484eb06e7ce792 upstream.
The driver and its bindings, before commit 04f9f068a619 ("regulator:
s5m8767: Modify parsing method of the voltage table of buck2/3/4") were
requiring to provide at least one safe/default voltage for DVS registers
if DVS GPIO is not being enabled.
IOW, if s5m8767,pmic-buck2-uses-gpio-dvs is missing, the
s5m8767,pmic-buck2-dvs-voltage should still be present and contain one
voltage.
This requirement was coming from driver behavior matching this condition
(none of DVS GPIO is enabled): it was always initializing the DVS
selector pins to 0 and keeping the DVS enable setting at reset value
(enabled). Therefore if none of DVS GPIO is enabled in devicetree,
driver was configuring the first DVS voltage for buck[234].
Mentioned commit 04f9f068a619 ("regulator: s5m8767: Modify parsing
method of the voltage table of buck2/3/4") broke it because DVS voltage
won't be parsed from devicetree if DVS GPIO is not enabled. After the
change, driver will configure bucks to use the register reset value as
voltage which might have unpleasant effects.
Fix this by relaxing the bindings constrain: if DVS GPIO is not enabled
in devicetree (therefore DVS voltage is also not parsed), explicitly
disable it.

commit 51308f36dcf3ef7c53a23159f44dc6766b1a93c9 from
git@git.assembla.com:cavium/WindRiver.linux.git
The Generic Hardware Error Source (GHES) allows for
non-standard errors to be reported to the system
(please refer to the ACPI specification).
The standard GHES driver requires the presence of
ACPI tables, and accompanying kernel ACPI support.
CN10K is commonly used in embedded context
with Device Tree and UEFI. Add support for DT and ACPI.
Add support for GHES through a platform driver,
using data from the Device Tree to construct the
required ACPI table (Hardware Error Source Table,
or HEST) and (Boot Error Record Table or BERT).
In ACPI based system use ACPI firmware tables.
The Boot Error Record Table (BERT) allows for the
reporting of [fatal] firmware errors which occurred
in a previous Linux boot. Due to the severity of
the error[s], the firmware could have chosen to
reset the system directly without informing the
kernel. BERT allows these errors to be reported
on a subsequent Linux boot.
For more information about BERT, please refer to ACPI
Specification version 6.0, section 18.3.1.
MRVL-EINJ: edac: RAS error-injection
Use SMC OCTEONTX_EDAC to inject ECC errors to DRAM & cache.
This provides an SMC error injection interface, for verifying
OcteonTX2's RAS/EDAC handling.
For example, injecting DRAM ECC single-bit error
at 8MB, and reading it back in EL3 ...
# edac=/sys/module/otx2_einj/parameters/smc_params
# echo 3,0x800000,0x300 >$edac
will cause ATF to inject error, field EL3 interrupt reporting it,
log that in the sdei-ghes area monitored by mrvl-ghes driver,
which passes details to generic edac_ghes driver, which logs
the following via syslog (which may display in /var/log/kern.log,
or elsewhere, depending on syslog configuration)

[ Upstream commit 778cb8e39f6ec252be50fc3850d66f3dcbd5dd5a ]
"PAGESIZE / 512" is the number of ECC chunks.
"ECC_BYTES" is the number of bytes needed to store a single ECC code.
"2" is the space reserved by the bad block marker.
"2 + (PAGESIZE / 512) * ECC_BYTES" should of course be lower or equal
than the total number of OOB bytes, otherwise it won't fit.
Fix the equation by substituting s/>=/<=/.

[ Upstream commit baf8d6899b1e8906dc076ef26cc633e96a8bb0c3 ]
The PWM pins on North Bridge on Armada 37xx can be configured into PWM
or GPIO functions. When in PWM function, each pin can also be configured
to drive low on 0 and tri-state on 1 (LED mode).
The current definitions handle this by declaring two pin groups for each
pin:
- group "pwmN" with functions "pwm" and "gpio"
- group "ledN_od" ("od" for open drain) with functions "led" and "gpio"
This is semantically incorrect. The correct definition for each pin
should be one group with three functions: "pwm", "led" and "gpio".
Change the "pwmN" groups to support "led" function.
Remove "ledN_od" groups. This cannot break backwards compatibility with
older device trees: no device tree uses it since there is no PWM driver
for this SOC yet. Also "ledN_od" groups are not even documented.

[ Upstream commit d1f278da6b11585f05b2755adfc8851cbf14a1ec ]
When scsi_dispatch_cmd was moved to scsi_lib.c and made static, some
compilers (i.e., at least gcc 8.4.0) decided to compile this
inline. This is a problem for lkdtm.ko, which inserted a kprobe
on this function for the SCSI_DISPATCH_CMD crashpoint.
Move this crashpoint one function up the call chain to
scsi_queue_rq. Though this is also a static function, it should never be
inlined because it is assigned as a structure entry. Therefore,
kprobe_register should always be able to find it.

[ Upstream commit 1c8094e394bceb4f1880f9d539bdd255c130826e ]
When the schema fixups are applied to 'select' the result is a single
entry is required for a match, but that will never match as there should
be 2 entries. Also, a 'select' schema should have the widest possible
match, so use 'contains' which matches the compatible string(s) in any
position and not just the first position.
