* Add interface luid to bpf_sock_addr and bpf_sock_ops
And also add compartment id to bpf_sock_ops for consistency with
bpf_sock_addr, so that it is available to eBPF programs.
Signed-off-by: Dave Thaler <dthaler@microsoft.com>
* Expose interface luid and compartment id to sock_ops and sock_addr hooks
* compartment_id was exposed to sock_addr but not sock_ops
* interface_luid was not exposed to either
Exposing the interface_luid should be a performant way to compensate for
lack of scope_id in the hooks, since the interface luid is available
in the WFP callout, and is more specific than a scope id (so a scope id
can always be looked up from the interface luid in the future if
needed).
