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

The function tipc_mon_rcv() allows a node to receive and process
domain_record structs from peer nodes to track their views of the
network topology.
This patch verifies that the number of members in a received domain
record does not exceed the limit defined by MAX_MON_DOMAIN, something
that may otherwise lead to a stack overflow.
tipc_mon_rcv() is called from the function tipc_link_proto_rcv(), where
we are reading a 32 bit message data length field into a uint16. To
avert any risk of bit overflow, we add an extra sanity check for this in
that function. We cannot see that happen with the current code, but
future designers being unaware of this risk, may introduce it by
allowing delivery of very large (> 64k) sk buffers from the bearer
layer. This potential problem was identified by Eric Dumazet.

commit
7938d61591d33394a21bdd7797a245b65428f44c upstream.
We need to flush TLBs before releasing backing store otherwise userspace
is able to encounter stale entries if a) it is not declaring access to
certain buffers and b) it races with the backing store release from a
such undeclared execution already executing on the GPU in parallel.
The approach taken is to mark any buffer objects which were ever bound
to the GPU and to trigger a serialized TLB flush when their backing
store is released.
Alternatively the flushing could be done on VMA unbind, at which point
we would be able to ascertain whether there is potential a parallel GPU
execution (which could race), but essentially it boils down to paying
the cost of TLB flushes potentially needlessly at VMA unbind time (when
the backing store is not known to be going away so not needed for
safety), versus potentially needlessly at backing store relase time
(since we at that point cannot tell whether there is anything executing
on the GPU which uses that object).
Thereforce simplicity of implementation has been chosen for now with
scope to benchmark and refine later as required.

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

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

EFI_VARIABLE_NON_VOLATILE bit before we trust it.

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.

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

Therefore, perform a basic check for the existence of

firmware: Remove redundant log messages from drivers

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.

iwlwifi: Do not request unreleased firmware for IWL6000
Bug-Debian: https://bugs.debian.org/689416
Forwarded: not-needed
The iwlwifi driver currently supports firmware API versions 4-6 for
these devices. It will request the file for the latest supported
version and then fall back to earlier versions. However, the latest
version that has actually been released is 4, so we expect the
requests for versions 6 and then 5 to fail.
The installer appears to report any failed request, and it is probably
not easy to detect that this particular failure is harmless. So stop
requesting the unreleased firmware.

kbuild: Abort build if SUBDIRS used
Forwarded: not-needed
Bug-Debian: https://bugs.debian.org/987575
DKMS and module-assistant both build OOT modules as root. If they
build an old OOT module that still use SUBDIRS this causes Kbuild
to try building a full kernel, which obviously fails but not before
deleting files from the installed headers package.
To avoid such mishaps, detect this situation and abort the build.

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.
