Can Ubuntu please consider addressing this as a part of the upcoming 24 LTS release? The ability to leverage LSM based BPF programs on Ubuntu out-of-the-box (ie. without having to update grub and rebooting) opens the door to a growing ecosystem of security tooling. There are major computing environments for which the community cannot control things like Grub settings - such as the Ubuntu images used by Microsoft (via GitHub Actions, Azure Pipelines), GitLab (via Jobs), AWS (via vanilla EC2 instances), etc.

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 Debian https://salsa.debian.org/kernel- team/linux/-/blob/master/debian/config/config?ref_type=heads#L7713 RedHat https://access.redhat.com/labs/rhcb/RHEL-8.9/kernel-4.18.0-513.18.1.el8/source/blob/redhat/configs/generic/CONFIG_LSM 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.
