2025-03-21arm: defconfig: drop RT_GROUP_SCHED=y from bcm2835/tegra/omap2plusCeleste Liu
Commit 673ce00c5d6c ("ARM: omap2plus_defconfig: Add support for distros with systemd") said it's because of recommendation from systemd. But systemd changed their recommendation later.[1] For cgroup v1, if turned on, and there's any cgroup in the "cpu" hierarchy it needs an RT budget assigned, otherwise the processes in it will not be able to get RT at all. The problem with RT group scheduling is that it requires the budget assigned but there's no way we could assign a default budget, since the values to assign are both upper and lower time limits, are absolute, and need to be sum up to < 1 for each individal cgroup. That means we cannot really come up with values that would work by default in the general case.[2] For cgroup v2, it's almost unusable as well. If it turned on, the cpu controller can only be enabled when all RT processes are in the root cgroup. But it will lose the benefits of cgroup v2 if all RT process were placed in the same cgroup. Red Hat, Gentoo, Arch Linux and Debian all disable it. systemd also doesn't support it.

2025-03-21landlock: Prepare to add second errataMickaël Salaün
Potentially include errata for Landlock ABI v5 (Linux 6.10) and v6 (Linux 6.12). That will be useful for the following signal scoping erratum. As explained in errata.h, this commit should be backportable without conflict down to ABI v5. It must then not include the errata/abi-6.h file.

2025-03-21landlock: Add the errata interfaceMickaël Salaün
Some fixes may require user space to check if they are applied on the running kernel before using a specific feature. For instance, this applies when a restriction was previously too restrictive and is now getting relaxed (e.g. for compatibility reasons). However, non-visible changes for legitimate use (e.g. security fixes) do not require an erratum. Because fixes are backported down to a specific Landlock ABI, we need a way to avoid cherry-pick conflicts. The solution is to only update a file related to the lower ABI impacted by this issue. All the ABI files are then used to create a bitmask of fixes. The new errata interface is similar to the one used to get the supported Landlock ABI version, but it returns a bitmask instead because the order of fixes may not match the order of versions, and not all fixes may apply to all versions. The actual errata will come with dedicated commits. The description is not actually used in the code but serves as documentation. Create the landlock_abi_version symbol and use its value to check errata consistency. Update test_base's create_ruleset_checks_ordering tests and add errata tests. This commit is backportable down to the first version of Landlock.

As the only user of acomp/scomp uses a trivial single-page SG list, remove support for everything else in preprataion for the addition of virtual address support. However, keep support for non-trivial source SG lists as that user is currently jumping through hoops in order to linearise the source data. Limit the source SG linearisation buffer to a single page as that user never goes over that. The only other potential user is also unlikely to exceed that (IPComp) and it can easily do its own linearisation if necessary. Also keep the destination SG linearisation for IPComp.
