tools/perf: pmu-events: Fix reproducibility
Forwarded: https://lore.kernel.org/lkml/

jevents.c uses nftw() to enumerate files and outputs the corresponding
C structs in the order they are found. This makes it sensitive to
directory ordering, so that the perf executable is not reproducible.
To avoid this, store all the files and directories found and then sort
them by their (relative) path. (This maintains the parent-first
ordering that nftw() promises.) Then apply the existing callbacks to
them in the sorted order.
Don't both storing the stat buffers as we don't need them.

cpupower: Fix checks for CPU existence
Forwarded: https://marc.info/?l=linux-pm&m=
149248268214265
Calls to cpufreq_cpu_exists(cpu) were converted to
cpupower_is_cpu_online(cpu) when libcpupower was introduced and the
former function was deleted. However, cpupower_is_cpu_online() does
not distinguish physically absent and offline CPUs, and does not set
errno.
cpufreq-set has already been fixed (commit
c25badc9ceb6).
In cpufreq-bench, which prints an error message for offline CPUs,
properly distinguish and report the zero and negative cases.

bpf, x86: Validate computation of branch displacements for x86-32
Origin: https://git.kernel.org/pub/scm/linux/kernel/git/bpf/bpf.git/patch/?id=
26f55a59dc65ff77cd1c4b37991e26497fc68049
Bug-Debian-Security: https://security-tracker.debian.org/tracker/CVE-2021-29154
The branch displacement logic in the BPF JIT compilers for x86 assumes
that, for any generated branch instruction, the distance cannot
increase between optimization passes.
But this assumption can be violated due to how the distances are
computed. Specifically, whenever a backward branch is processed in
do_jit(), the distance is computed by subtracting the positions in the
machine code from different optimization passes. This is because part
of addrs[] is already updated for the current optimization pass, before
the branch instruction is visited.
And so the optimizer can expand blocks of machine code in some cases.
This can confuse the optimizer logic, where it assumes that a fixed
point has been reached for all machine code blocks once the total
program size stops changing. And then the JIT compiler can output
abnormal machine code containing incorrect branch displacements.
To mitigate this issue, we assert that a fixed point is reached while
populating the output image. This rejects any problematic programs.
The issue affects both x86-32 and x86-64. We mitigate separately to
ease backporting.

That's better for checking the attributes of db and mok variables
before loading certificates to kernel keyring.
For db and dbx, both of them are authenticated variables. Which
means that they can only be modified by manufacturer's key. So
the kernel should checks EFI_VARIABLE_TIME_BASED_AUTHENTICATED_WRITE_ACCESS
attribute before we trust it.
For mok-rt and mokx-rt, both of them are created by shim boot loader
to forward the mok/mokx content to runtime. They must be runtime-volatile
variables. So kernel should checks that the attributes map did not set
EFI_VARIABLE_NON_VOLATILE bit before we trust it.

The Marvell PHY was originally disabled because it can cause networking
failures on some systems. According to Lennert Buytenhek this is because some
of the variants added did not share the same register layout. Since the known
cases are all 4-ports disable those variants (indicated by a 4 in the
penultimate position of the model name) until they can be audited for
correctness.

x86: Make x32 syscall support conditional on a kernel parameter
Bug-Debian: https://bugs.debian.org/708070
Forwarded: https://lore.kernel.org/lkml/
1415245982.3398.53.camel@decadent.org.uk/T/#u
Enabling x32 in the standard amd64 kernel would increase its attack
surface while provide no benefit to the vast majority of its users.
No-one seems interested in regularly checking for vulnerabilities
specific to x32 (at least no-one with a white hat).
Still, adding another flavour just to turn on x32 seems wasteful. And
the only differences on syscall entry are a few instructions that mask
out the x32 flag and compare the syscall number.
Use a static key to control whether x32 syscalls are really enabled, a
Kconfig parameter to set its default value and a kernel parameter
"syscall.x32" to change it at boot time.

x86-32: Disable 3D-Now in generic config
We want the 686 flavour to run on Geode LX and similar AMD family 5
CPUs as well as family 6 and higher CPUs. This used to work with
CONFIG_M686=y. However commit
25d76ac88821 "x86/Kconfig: Explicitly

It looks like a sensible choice would be to enable CONFIG_MGEODE_LX

currently enables CONFIG_X86_USE_3D_NOW which will cause the kernel to
crash on CPUs without the AMD-specific 3D-Now instructions.

If firmware loading fails due to a missing file, log a second error

why some firmware is in non-free, or can't be packaged at all. Only

radeon requires firmware/microcode for the GPU in all chips, but for
newer chips (apparently R600 'Evergreen' onward) it also expects
firmware for the memory controller and other sub-blocks.
radeon attempts to gracefully fall back and disable some features if
the firmware is not available, but becomes unstable - the framebuffer
and/or system memory may be corrupted, or the display may stay black.
Therefore, perform a basic check for the existence of
/lib/firmware/{radeon,amdgpu} when a device is probed, and abort if it
is missing, except for the pre-R600 case.

firmware_class: Log every success and failure against given device
Forwarded: no
The hundreds of users of request_firmware() have nearly as many
different log formats for reporting failures. They also have only the
vaguest hint as to what went wrong; only firmware_class really knows
that. Therefore, add specific log messages for the failure modes that
aren't currently logged.
In case of a driver that tries multiple names, this may result in the
impression that it failed to initialise. Therefore, also log successes.
This makes many error messages in drivers redundant, which will be
removed in later patches.
This does not cover the case where we fall back to a user-mode helper
(which is no longer enabled in Debian).
NOTE: hw-detect will depend on the "firmware: failed to load %s (%d)\n"
format to detect missing firmware.

The iwlwifi driver currently supports firmware API versions 4-6 for
these devices. It will request the file for the latest supported

kbuild: Look for module.lds under arch directory too
Forwarded: not-needed
Bug-Debian: https://bugs.debian.org/975571
The module.lds linker script is now built under the scripts directory,
where previously it was under arch/$(SRCARCH).
However, we package the scripts directory as linux-kbuild, which is
meant to be able to do support native and cross-builds. That means it
shouldn't contain files for a specific target architecture without a
wrapper to select between them, and it doesn't appear that linker
scripts are powerful enough to implement such a wrapper.
Building module.lds in a different location would require relatively
large changes. Moving it in the package build rules can work, but we
need to support custom kernel builds from the same source so we can't
assume it's moved.
Therefore, we move module.lds under the arch build directory in
rules.real and change Makefile.modfinal to look for it in both places.

Hardcode arch script output
Bug-Debian: https://bugs.debian.org/392592
Forwarded: not-needed
Here's a patch that simply uses hardcoded definitions instead of
doing the dynamic tests that require architecture-specific scripts.
I don't particularly like this approach because it restricts
portability and diverts from upstream. But, it is simpler, and this
really needs to be fixed somehow before etch (along with a rebuild of
linux-modules-extra-2.6), so I'm willing to live with it if my other
patch is deemed unacceptable.
My primary concern is that, in the future, the output of these scripts
will change and we (or our successors) will either not notice or
forget to update the hardcoded values.
Including the scripts in linux-kbuild will avoid this manual step
altogether, and allow for the possibility of other archs to provide
their own scripts in the future.
