KP Singh 6f64e47783 bpf: Update verification logic for LSM programs ... The current logic checks if the name of the BTF type passed in attach_btf_id starts with "bpf_lsm_", this is not sufficient as it also allows attachment to non-LSM hooks like the very function that performs this check, i.e. bpf_lsm_verify_prog. In order to ensure that this verification logic allows attachment to only LSM hooks, the LSM_HOOK definitions in lsm_hook_defs.h are used to generate a BTF_ID set. Upon verification, the attach_btf_id of the program being attached is checked for presence in this set.
