The latest image of Alibaba Cloud Linux 3 contains BPF-LSM enabled by default as part of the kernel config but not enabled by default as part of the boot parameter. Thus the user has to enable the bpf-lsm boot parameter for all the nodes for which they desire that the enforcement should work. This (and this for k8s) FAQ helps user with enabling bpf-lsm for VM and k8s env. Note that the nodes will be restarted once for the bpf-lsm boot parameter to come into effect.

The detailed linux-kernel-config for Alibaba Cloud Linux 3 can be found here.
