[PATCH] kselftest/cgroup: Add cleanup() to test_cpuset_prs.sh

by Kamalesh Babulal

Install a cleanup function using the trap command for signals EXIT, SIGINT, SIGQUIT and SIGABRT. The cleanup function will perform: 1. Online the CPUs that were made offline during the test. 2. Removing the cgroups created. 3. Restoring the original /sys/kernel/debug/sched/verbose value, currently it's left turned on, irrespective of the original configuration value. the test performs steps 1 and 2, on the successful runs, but not during all of the failed runs. With the cleanup(), the system will perform all three steps during failed/passed test runs.

[PATCH net-next v2 1/2] selftests: bonding: up/down delay w/ slave link flapping

Verify when a bond is configured with {up,down}delay and the link state of slave members flaps if there are no remaining members up the bond should immediately select a member to bring up.

[PATCH RFC 00/19] mm/gup: remove FOLL_FORCE usage from drivers (reliable R/O long-term pinning)

by David Hildenbrand

For now, we did not support reliable R/O long-term pinning in COW mappings. That means, if we would trigger R/O long-term pinning in MAP_PRIVATE mapping, we could end up pinning the (R/O-mapped) shared zeropage or a pagecache page. The next write access would trigger a write fault and replace the pinned page by an exclusive anonymous page in the process page table; whatever the process would write to that private page copy would not be visible by the owner of the previous page pin: for example, RDMA could read stale data. The end result is essentially an unexpected and hard-to-debug memory corruption. Some drivers tried working around that limitation by using "FOLL_FORCE|FOLL_WRITE|FOLL_LONGTERM" for R/O long-term pinning for now. FOLL_WRITE would trigger a write fault, if required, and break COW before pinning the page. FOLL_FORCE is required because the VMA might lack write permissions, and drivers wanted to make that working as well, just like one would expect (no write access, but still triggering a write access to break COW). However, that is not a practical solution, because (1) Drivers that don't stick to that undocumented and debatable pattern would still run into that issue. For example, VFIO only uses FOLL_LONGTERM for R/O long-term pinning. (2) Using FOLL_WRITE just to work around a COW mapping + page pinning limitation is unintuitive. FOLL_WRITE would, for example, mark the page softdirty or trigger uffd-wp, even though, there actually isn't going to be any write access. (3) The purpose of FOLL_FORCE is debug access, not access without lack of VMA permissions by arbitrarty drivers. So instead, make R/O long-term pinning work as expected, by breaking COW in a COW mapping early, such that we can remove any FOLL_FORCE usage from drivers. More details in patch #8. Patches #1--#3 add COW tests for non-anonymous pages. Patches #4--#7 prepare core MM for extended FAULT_FLAG_UNSHARE support in COW mappings. Patch #8 implements reliable R/O long-term pinning in COW mappings Patches #9--#19 remove any FOLL_FORCE usage from drivers. I'm refraining from CCing all driver maintainers on the whole patch set.

[PATCH net-next] selftests: net: Add cross-compilation support for BPF programs

by Björn Töpel

From: Björn Töpel <bjorn(a)rivosinc.com> The selftests/net does not have proper cross-compilation support, and does not properly state libbpf as a dependency. Mimic/copy the BPF build from selftests/bpf, which has the nice side-effect that libbpf is built as well. Signed-off-by: Björn Töpel <bjorn(a)rivosinc.com> --- Now that BPF builds are starting to show up in more places (selftests/net, and soon selftests/hid), maybe it would be cleaner to move parts of the BPF builds to lib.mk?
