| debian/dfsg/video-remove-nvidiafb-and-rivafb.patch | video: Remove nvidiafb and rivafb These drivers contain register programming code provided by the hardware vendor that appears to have been deliberately obfuscated. This is arguably not the preferred form for modification. These drivers are also largely redundant with nouveau. The RIVA 128 (NV3) is not supported by nouveau but is about 15 years old and probably discontinued 10 years ago. |

| debian/uname-version-timestamp.patch | Make mkcompile_h accept an alternate timestamp string We want to include the Debian version in the utsname::version string instead of a full timestamp string. However, we still need to provide a standard timestamp string for gen_initramfs_list.sh to make the kernel image reproducible. Make mkcompile_h use $KBUILD_BUILD_VERSION_TIMESTAMP in preference to $KBUILD_BUILD_TIMESTAMP. =================================================================== |

| debian/kernelvariables.patch | kbuild: Make the toolchain variables easily overwritable Allow make variables to be overridden for each flavour by a file in the build tree, .kernelvariables. We currently use this for ARCH, KERNELRELEASE, CC, and in some cases also CROSS_COMPILE, KCFLAGS. This file can only be read after we establish the build tree, and all use of $(ARCH) needs to be moved after this. [bwh: Updated for 5.3: include .kernelvariables from current directory rather than using undefined $(obj).] |

| debian/export-symbols-needed-by-android-drivers.patch | Export symbols needed by Android drivers 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. Export the currently un-exported symbols they depend on. |

| debian/android-enable-building-ashmem-and-binder-as-modules.patch | android: Enable building ashmem and binder as modules 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. |

| debian/kbuild-look-for-module.lds-under-arch-directory-too.patch | kbuild: Look for module.lds under arch directory too 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. |

| debian/kbuild-abort-build-if-subdirs-used.patch | kbuild: Abort build if SUBDIRS used 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". |

| debian/module-avoid-abi-changes-when-debug-info-is-disabled.patch | module: Avoid ABI changes when debug info is disabled CI builds are done with debug info disabled, but this removes some members from struct module. This causes builds to fail if there is an ABI reference for the current ABI. Define these members unconditionally, so that there is no ABI change. |
Ben Hutchings <benh@debian.org> | not-needed | 2022-05-13 | ||
| debian/makefile-make-compiler-version-comparison-optional.patch | Makefile: Make compiler version comparison optional 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. |

| debian/fixdep-allow-overriding-hostcc-and-hostld.patch | fixdep: Allow overriding HOSTCC and HOSTLD 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. Add support for REALHOSTCC and REALHOSTLD variables which, if set, override HOSTCC and HOSTLD for fixdep only. |

| features/all/drivers-media-dvb-usb-af9005-request_firmware.patch | af9005: Use request_firmware() to load register init script Read the register init script from the Windows driver.

| debian/iwlwifi-do-not-request-unreleased-firmware.patch | iwlwifi: Do not request unreleased firmware for IWL6000 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. |

| bugfix/all/firmware_class-log-every-success-and-failure.patch | firmware_class: Log every success and failure against given device 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). format to detect missing firmware. |

| bugfix/all/firmware-remove-redundant-log-messages-from-drivers.patch | firmware: Remove redundant log messages from drivers Now that firmware_class logs every success and failure consistently, many other log messages can be removed from drivers.

| bugfix/all/radeon-amdgpu-firmware-is-required-for-drm-and-kms-on-r600-onward.patch | radeon, amdgpu: Firmware is required for DRM and KMS on R600 onward 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: In bug 1053764 Mario Limonciello <mario.limonciello@amd.com> states that the patch isn't needed anymore for amdgpu, so remove that part of the patch |

| debian/firmware_class-refer-to-debian-wiki-firmware-page.patch | firmware_class: Refer to Debian wiki page when logging missing firmware If firmware loading fails due to a missing file, log a second error message referring to our wiki page about firmware. This will explain why some firmware is in non-free, or can't be packaged at all. Only do this once per boot. Do something similar in the radeon drivers, where we have an early check to avoid failing at a point where we cannot display anything.

| debian/af_802154-Disable-auto-loading-as-mitigation-against.patch | [PATCH 2/3] af_802154: Disable auto-loading as mitigation against local exploits 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. |

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. |

Unprivileged use of CLONE_NEWUSER is certainly an intended feature of user namespaces. However for at least saucy we want to make sure that, if any security issues are found, we have a fail-safe.

Add a Kconfig symbol CONFIG_SECURITY_PERF_EVENTS_RESTRICT that makes this value the default. This is based on a similar feature in grsecurity (CONFIG_GRKERNSEC_PERF_HARDEN). This version doesn't include making the variable read-only. It also allows enabling further restriction at run-time regardless of whether the default is changed. |

| features/x86/intel-iommu-add-option-to-exclude-integrated-gpu-only.patch | intel-iommu: Add option to exclude integrated GPU only 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=intgpu_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. |

| debian/snd-pcsp-disable-autoload.patch | snd-pcsp: Disable autoload There are two drivers claiming the platform:pcspkr device: - pcspkr creates an input(!) device that can only beep - snd-pcsp creates an equivalent input device plus a PCM device that can play barely recognisable renditions of sampled sound snd-pcsp is blacklisted by the alsa-base package, but not everyone installs that. On PCs where no sound is wanted at all, both drivers will still be loaded and one or other will complain that it couldn't claim the relevant I/O range. In case anyone finds snd-pcsp useful, we continue to build it. But remove the alias, to ensure it's not loaded where it's not wanted. |

Currently, it is blacklisted by udev along with most other framebuffer drivers, so this doesn't matter much. However, this driver is required for console support on the XO 1.5. We need to allow it to be autoloaded on this model only, and then un-blacklist it in udev. |

However some shells, including dash, will not pass through environment variables whose name includes a hyphen. Usually GNU make does not use a shell to recurse, but if e.g. $(srctree) contains '~' it will use a shell here. Rename the variable to ld_bfd.

The call to __sync_icache_dcache() may be optimised out because it is conditional on !pte_special(), and xen-privcmd calls pte_mkspecial(). However, in a non-LPAE configuration there is no "special" bit and the call is really unconditional. |

| bugfix/alpha/alpha-fix-missing-symbol-versions-for-str-n-cat-cpy.patch | alpha: Fix missing symbol versions for str{,n}{cat,cpy} Now that modpost extracts symbol versions from *.cmd files, it can't find the versions for these 4 symbols. This is due to the way we link their objects together ahead of the full vmlinux link. genksyms puts their symbol CRCs in .str{,n}{cat,cpy}.o.cmd, but modpost only reads the .sty{,n}cpy.o.cmd files. Add assembly sources that bring the appropriate routines together with include directives instead of using the linker for this. |

| features/x86/x86-make-x32-syscall-support-conditional.patch | 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. |

| bugfix/all/disable-some-marvell-phys.patch | phy/marvell: disable 4-port phys The Marvell PHY was originally disabled because it can cause networking failures on some systems.
