More details here: https://www.kernel.org/doc/html/v5.9/bpf/bpf_lsm.html There are already projects trying to leverage that systemd with the restrict-fs feature https://github.com/systemd/systemd/blob/main/src/core/bpf/restrict_fs/restrict-fs.bpf.c https://github.com/linux-lock/bpflock https://github.com/lockc-project/lockc However, BPF LSM has to be enabled by adding bpf to CONFIG_LSM. That was already done in: Arch Linux https://github.com/archlinux/svntogit- packages/blob/4615bb2493649ad6fa133f864f94cb95c824f361/trunk/config#L9963 Fedora https://fedorapeople.org/cgit/thl/public_git/kernel.git/tree/kernel-x86_64-fedora.config?h=kernel-5.17.0-0.rc5.20220225git53ab78cd6d5a.106.vanilla.1.fc34&id=e661d91eb909e777a9d28425ef50fcc5ef7fa5ed#n3291 openSUSE https://github.com/openSUSE/kernel- source/commit/c2c25b18721866d6211054f542987036ed6e0a50 Could we please enable BPF LSM in Ubuntu kernels as well? Without that change, users trying to play with the mentioned projects have to edit their /etc/default/grub to add bpf LSM.
