- It turns out that the optimised string routines merged in 5.14 are not
safe with in-kernel MTE (KASAN_HW_TAGS) because of reading beyond the
end of a string (strcmp, strncmp). Such reading may go across a 16
byte tag granule and cause a tag check fault. When KASAN_HW_TAGS is
enabled, use the generic strcmp/strncmp C implementation.
- An errata workaround for ThunderX relied on the CPU capabilities being
enabled in a specific order. This disappeared with the automatic
generation of the cpucaps.h file (sorted alphabetically). Fix it by
checking the current CPU only rather than the system-wide capability.
- Add system_supports_mte() checks on the kernel entry/exit path and
thread switching to avoid unnecessary barriers and function calls on
systems where MTE is not supported.

Update the current state as boot state during dpm initialization.
During the subsequent initialization, set_power_state gets called to
transition to the final power state. set_power_state refers to values
from the current state and without current state populated, it could
result in NULL pointer dereference.
For ex: on platforms where PCI speed change is supported through ACPI
ATCS method, the link speed of current state needs to be queried before
deciding on changing to final power state's link speed. The logic to query
ATCS-support was broken on certain platforms. The issue became visible
when broken ATCS-support logic got fixed with commit
f9b7f3703f ("drm/amdgpu/acpi: make ATPX/ATCS structures global (v2)").

This reverts commit 437b38c511.
The memory semantics added in commit 437b38c511 causes SystemMemory
Operation region, whose address range is not described in the EFI memory
map to be mapped as NormalNC memory on arm64 platforms (through
acpi_os_map_memory() in acpi_ex_system_memory_space_handler()).
This triggers the following abort on an ARM64 Ampere eMAG machine,
because presumably the physical address range area backing the Opregion
does not support NormalNC memory attributes driven on the bus.

If the Opregion address range is not present in the EFI memory map there
is no way for us to determine the memory attributes to use to map it -
defaulting to NormalNC does not work (and it is not correct on a memory
region that may have read side-effects) and therefore commit
437b38c511 should be reverted, which means reverting back to the
original behavior whereby address ranges that are mapped using
acpi_os_map_memory() default to the safe devicenGnRnE attributes on
ARM64 if the mapped address range is not defined in the EFI memory map.

Prior to the commit 7e1c0d6f58 ("memcg: switch lruvec stats to rstat")
and the commit aa48e47e39 ("memcg: infrastructure to flush memcg
stats"), each lruvec memcg stats can be off by (nr_cgroups * nr_cpus *
32) at worst and for unbounded amount of time. The commit aa48e47e39
moved the lruvec stats to rstat infrastructure and the commit
7e1c0d6f58 bounded the error for all the lruvec stats to (nr_cpus *
32) at worst for at most 2 seconds. More specifically it decoupled the
number of stats and the number of cgroups from the error rate.
However this reduction in error comes with the cost of triggering the
slowpath of stats update more frequently. Previously in the slowpath
the kernel adds the stats up the memcg tree. After aa48e47e39, the
kernel triggers the asyn lruvec stats flush through queue_work(). This
causes regression reports from 0day kernel bot [1] as well as from
phoronix test suite [2].
We tried two options to fix the regression:
1) Increase the threshold to trigger the slowpath in lruvec stats
update codepath from 32 to 512.
2) Remove the slowpath from lruvec stats update codepath and instead
flush the stats in the page refault codepath. The assumption is that
the kernel timely flush the stats, so, the update tree would be
small in the refault codepath to not cause the preformance impact.
Following are the results of will-it-scale/page_fault[1|2|3] benchmark
on four settings i.e. (1) 5.15-rc1 as baseline (2) 5.15-rc1 with
aa48e47e39 and 7e1c0d6f58 reverted (3) 5.15-rc1 with option-1
(4) 5.15-rc1 with option-2.
test (1) (2) (3) (4)
pg_f1 368563 406277 (10.23%) 399693 (8.44%) 416398 (12.97%)
pg_f2 338399 372133 (9.96%) 369180 (9.09%) 381024 (12.59%)
pg_f3 500853 575399 (14.88%) 570388 (13.88%) 576083 (15.02%)
From the above result, it seems like the option-2 not only solves the
regression but also improves the performance for at least these
benchmarks.
Feng Tang (intel) ran the aim7 benchmark with these two options and
confirms that option-1 reduces the regression but option-2 removes the
regression.
Michael Larabel (phoronix) ran multiple benchmarks with these options
and reported the results at [3] and it shows for most benchmarks
option-2 removes the regression introduced by the commit aa48e47e39
("memcg: infrastructure to flush memcg stats").
Based on the experiment results, this patch proposed the option-2 as the
solution to resolve the regression.

Jann Horn reported a problem with commit eb1231f73c ("selinux:
clarify task subjective and objective credentials") where some LSM
hooks were attempting to access the subjective credentials of a task
other than the current task. Generally speaking, it is not safe to
access another task's subjective credentials and doing so can cause
a number of problems.
Further, while looking into the problem, I realized that Smack was
suffering from a similar problem brought about by a similar commit
1fb057dcde ("smack: differentiate between subjective and objective
task credentials").
This patch addresses this problem by restoring the use of the task's
objective credentials in those cases where the task is other than the
current executing task. Not only does this resolve the problem
reported by Jann, it is arguably the correct thing to do in these
cases.

Currently, the whole indexes will only be compacted 4B if
compacted_4b_initial > totalidx. So, the calculated compacted_2b
is worthless for that case. It may waste CPU resources.
No need to update compacted_4b_initial as mkfs since it's used to
fulfill the alignment of the 1st compacted_2b pack and would handle
the case above.
We also need to clarify compacted_4b_end here. It's used for the
last lclusters which aren't fitted in the previous compacted_2b
packs.
Some messages are from Xiang.

A noted side-effect of commit 0c6c2d3615 ("arm64: Generate cpucaps.h")
is that cpucaps are now sorted, changing the enumeration order. This
assumed no dependencies between cpucaps, which turned out not to be true
in one case. UNMAP_KERNEL_AT_EL0 currently needs to be processed after
WORKAROUND_CAVIUM_27456. ThunderX systems are incompatible with KPTI, so
unmap_kernel_at_el0() bails if WORKAROUND_CAVIUM_27456 is set. But because
of the sorting, WORKAROUND_CAVIUM_27456 will not yet have been considered
when unmap_kernel_at_el0() checks for it, so the kernel tries to
run w/ KPTI - and quickly falls over.
Because all ThunderX implementations have homogeneous CPUs, we can remove
this dependency by just checking the current CPU for the erratum.

After fixing hibernation resume flow, another usecase was found which
should be explicitly handled - resume when device is in "down" state.
Invoke aq_nic_init jointly with aq_nic_start only if ndev was already
up during suspend/hibernate. We still need to perform nic_deinit() if
caller requests for it, to handle the freeze/resume scenarios.

The blamed commit made the fatally incorrect assumption that ports which
aren't in the FORWARDING STP state should not have packets forwarded
towards them, and that is all that needs to be done.
However, that logic alone permits BLOCKING ports to forward to
FORWARDING ports, which of course allows packet storms to occur when
there is an L2 loop.
The ocelot_get_bridge_fwd_mask should not only ask "what can the bridge
do for you", but "what can you do for the bridge". This way, only
FORWARDING ports forward to the other FORWARDING ports from the same
bridging domain, and we are still compatible with the idea of multiple
bridges.
