The information about the different types of LSM hooks is scattered in two locations i.e. union security_list_options and struct security_hook_heads. Rather than duplicating this information even further for BPF_PROG_TYPE_LSM, define all the hooks with the LSM_HOOK macro in lsm_hook_defs.h which is then used to generate all the data structures required by the LSM framework. The LSM hooks are defined as: LSM_HOOK(<return_type>, <default_value>, <hook_name>, args...) with <default_value> acccessible in security.c as: LSM_RET_DEFAULT(<hook_name>) Signed-off-by:
