Btw "xdp_cpumap" should be cleaned up.
xdp_cpumap is an attach type. It's not prog type.
Probably it should be "xdp/cpumap" to align with "cgroup/bind[46]" ?
so for xdp "mb" or xdp "frags" it will be xdp/cpumap.mb (xdp/devmap.mb) or
xdp/cpumap.frags (xdp/devmap.frags), right?
xdp.frags/cpumap
xdp.frags/devmap
The current de-facto standard for SEC("") in libbpf:
prog_type.prog_flags/attach_place
Ups, did we make a mistake with SEC("xdp_devmap/")
and can we correct without breaking existing programs?
"attach_place" is either function_name for fentry/, tp/, lsm/, etc.
or attach_type/hook/target for cgroup/bind4, cgroup_skb/egress.
lsm.s/socket_bind -> prog_type = LSM, flags = SLEEPABLE
lsm/socket_bind -> prog_type = LSM, non sleepable.
