2018-05-14samples: bpf: include bpf/bpf.h instead of local libbpf.hJakub Kicinski1-1/+1
There are two files in the tree called libbpf.h which is becoming problematic. Most samples don't actually need the local libbpf.h they simply include it to get to bpf/bpf.h. Include bpf/bpf.h directly instead.

2017-07-01bpf: program to load and attach sock_ops BPF progsLawrence Brakmo1-0/+97
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.
