[PATCH 1/3] rds: Disable auto-loading as mitigation against local exploits
Forwarded: not-needed
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 'rds' protocol is one such protocol that has been found to be
vulnerable, and which was not present in the 'lenny' kernel.
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 when a device is probed, and abort if it
is missing, except for the pre-R600 case.
Update 2023-11-08:

firmware_loader: Log direct loading failures as info for d-i
Forwarded: not-needed
On an installed Debian system, firmware packages will normally be
installed automatically based on a mapping of device IDs to firmware.
Within the Debian installer this has not yet happened and we need a
way to detect missing firmware.
Although many/most drivers log firmware loading failures, they do so
using many different formats. This adds a single log message to the
firmware loader, which the installer's hw-detect package will look
for. The log level is set to "info" because some failures are
expected and we do not want to confuse users with bogus error messages
(like in bug #966218).
NOTE: The log message format must not be changed without coordinating
this with the check-missing-firmware.sh in hw-detect.

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.

fixdep: Allow overriding HOSTCC and HOSTLD
Forwarded: not-needed
objtool always uses HOSTCC, HOSTLD, and HOSTAR, so we need to override
these on the command line for cross-builds of linux-kbuild. But it
also builds fixdep which still needs to be native in a cross-build.

The top-level Makefile warns if the compiler version string changes at
all between the kernel build and an out-of-tree module build.
We expect that major compiler version changes could introduce ABI
changes, and override the CC variable in out-of-tree module builds to
ensure that the same major compiler version is used. But minor
version changes should not make a difference, so this exact version
comparison produces false warnings.
Since custom kernel packages don't have that, don't remove the version
comparison. Instead, skip it if $(DEBIAN_KERNEL_NO_CC_VERSION_CHECK)
is non-empty.

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.
The error message is based on that used in commit 0126be38d988
"kbuild: announce removal of SUBDIRS if used".

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.

android: Enable building ashmem and binder as modules
Bug-Debian: https://bugs.debian.org/901492
We want to enable use of the Android ashmem and binder drivers to
support Anbox, but they should not be built-in as that would waste
resources and increase security attack surface on systems that don't
need them.
- Add a MODULE_LICENSE declaration to ashmem
- Change the Makefiles to build each driver as an object with the
"_linux" suffix (which is what Anbox expects)
- Change config symbol types to tristate
Update:
In upstream commit 721412ed3d titled "staging: remove ashmem" the ashmem
driver was removed entirely. Secondary commit message:
"The mainline replacement for ashmem is memfd, so remove the legacy
code from drivers/staging/"
Consequently, the ashmem part of this patch has been removed.
