Hi all, This patch series includes backports for the changes that fix CVE-2023-52447. The changes were applied cleanly from my 5.15 backport, viewable at https://lore.kernel.org/stable/cover.1710187165.git.rkolchmeyer@xxxxxxxxxx/T/#t. The notes in that patch set largely apply here. The only note I have for 5.10 is that the test cases with sleepable BPF programs in commit 1624918be84a ("selftests/bpf: Add test cases for inner map") do not seem to be compatible with the 5.10 kernel. But the situation with the other test cases matches the observations I shared in the 5.15 patch set. Thanks, -Robert Hou Tao (1): bpf: Defer the free of inner map when necessary Paul E.
