linux-toradex.git/samples/bpf/load_sock_ops.c, branch v4.14 Linux kernel for Apalis and Colibri modules bpf: program to load and attach sock_ops BPF progs 2017-07-01T23:15:13+00:00 Lawrence Brakmo brakmo@fb.com 2017-07-01T03:02:41+00:00 ae16189efb0fe2bdc5e702bd6221ed6d0ff5babd 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.

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.
