ovl: permit overlayfs mounts in user namespaces (taints kernel)
Permit overlayfs mounts within user namespaces to allow utilisation of e.g.
unprivileged LXC overlay snapshots.
Except by the Ubuntu community [1], overlayfs mounts in user namespaces are
expected to be a security risk [2] and thus are not enabled on upstream
Linux kernels. For the non-Ubuntu users that have to stick to unprivileged
overlay-based LXCs, this meant to patch and compile the kernel manually.
Instead, adding the kernel tainting 'permit_mounts_in_userns' module
parameter allows a kind of a user-friendly way to enable the feature.
Testable with:
sudo modprobe overlay permit_mounts_in_userns=1
sudo sysctl -w kernel.unprivileged_userns_clone=1
mkdir -p lower upper work mnt
unshare --map-root-user --mount \
mount -t overlay none mnt \
-o lowerdir=lower,upperdir=upper,workdir=work

do_install with DESTDIR as part of the second argument.
But do_install is again using '$(DESTDIR_SQ)$2', so as a result the

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

them in the sorted order.
Don't both storing the stat buffers as we don't need them.

For db and dbx, both of them are authenticated variables. Which

the kernel should checks EFI_VARIABLE_TIME_BASED_AUTHENTICATED_WRITE_ACCESS

For mok-rt and mokx-rt, both of them are created by shim boot loader

These drivers allow mapping arbitrary memory ranges as MTD devices.
This should be disabled to preserve the kernel's integrity when it is
locked down.
* Add the HWPARAM flag to the module parameters
* When slram is built-in, it uses __setup() to read kernel parameters,
so add an explicit check security_locked_down() check

Make an option to provide a sysrq key that will lift the kernel lockdown,
thereby allowing the running kernel image to be accessed and modified.
On x86 this is triggered with SysRq+x, but this key may not be available on

Since this macro must be defined in an arch to be able to use this facility

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.

intel-iommu: Add option to exclude integrated GPU only
Bug-Debian: https://bugs.debian.org/935270
Bug-Kali: https://bugs.kali.org/view.php?id=5644
There is still laptop firmware that touches the integrated GPU behind
the operating system's back, and doesn't say so in the RMRR table.
Enabling the IOMMU for all devices causes breakage, but turning it off
for all graphics devices seems like a major weakness.
Add an option, intel_iommu=igpu_off, to exclude only integrated GPUs
from remapping. This is a narrower exclusion than igfx_off: it only
affects Intel devices on the root bus. Devices attached through an
external port (Thunderbolt or ExpressCard) won't be on the root bus.

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

Here's a patch that simply uses hardcoded definitions instead of

I don't particularly like this approach because it restricts

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
