bpftool: Fix version string in recursive builds
Forwarded: https://lore.kernel.org/bpf/
20200813235837.GA497088@decadent.org.uk/T/#u
When bpftool is built as part of a Debian package build, which itself
uses make, "bpftool version" shows:
bpftool vmake[4]: Entering directory /build/linux-5.8/tools/bpf/bpftool 5.8.8.0 make[4]: Leaving directory /build/linux-5.8
Although we pass the "--no-print-directory" option, this is overridden
by the environment variable "MAKEFLAGS=w". Clear MAKEFLAGS for the
"make kernelversion" command.
I have no explanation for the doubled ".8" in the version string, but
this seems to fix that as well.

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

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

cpufreq-set has already been fixed (commit

properly distinguish and report the zero and negative cases.

[PATCH 4/4] MODSIGN: check the attributes of db and mok
Origin: https://lore.kernel.org/patchwork/patch/933176/
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.

x86: Make x32 syscall support conditional on a kernel parameter

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
enumerate i686-class CPUs in Kconfig" in Linux 4.16 has made the
kernel require family 6 or higher.
It looks like a sensible choice would be to enable CONFIG_MGEODE_LX
and CONFIG_X86_GENERIC (for more generic optimisations), but this
currently enables CONFIG_X86_USE_3D_NOW which will cause the kernel to
crash on CPUs without the AMD-specific 3D-Now instructions.
Make CONFIG_X86_USE_3DNOW depend on CONFIG_X86_GENERIC being disabled.

Recent review has revealed several bugs in obscure protocol
implementations that can be exploited by local users for denial of
service or privilege escalation. We can mitigate the effect of any
remaining vulnerabilities in such protocols by preventing unprivileged
users from loading the modules, so that they are only exploitable on
systems where the administrator has chosen to load the protocol.
The 'af_802154' (IEEE 802.15.4) protocol is not widely used, was
not present in the 'lenny' kernel, and seems to receive only sporadic
maintenance. Therefore disable auto-loading.

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

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.
