bpf: program to load and attach sock_ops BPF progs
The program load_sock_ops can be used to load sock_ops bpf programs and
to attach it to an existing (v2) cgroup. It can also be used to detach
sock_ops programs.
Examples:
load_sock_ops [-l] <cg-path> <prog filename>
Load and attaches a sock_ops program at the specified cgroup.
If "-l" is used, the program will continue to run to output the
BPF log buffer.
If the specified filename does not end in ".o", it appends
"_kern.o" to the name.
load_sock_ops -r <cg-path>
Detaches the currently attached sock_ops program from the
specified cgroup.
