Add a new API to pin a BPF object to the filesystem. The user can specify the path within a BPF filesystem to pin the object. Programs will be pinned under a subdirectory named the same as the program, with each instance appearing as a numbered file under that directory, and maps will be pinned under the path using the name of the map as the file basename. For example, with the directory '/sys/fs/bpf/foo' and a BPF object which contains two instances of a program named 'bar', and a map named 'baz': /sys/fs/bpf/foo/bar/0 /sys/fs/bpf/foo/bar/1 /sys/fs/bpf/foo/baz Signed-off-by: Joe Stringer <joe@ovn.org> Cc: Alexei Starovoitov <ast@fb.com> Cc: Daniel Borkmann <daniel@iogearbox.net> Cc: Wang Nan <wangnan0@huawei.com> Cc: netdev@vger.kernel.org Link: http://lkml.kernel.org/r/20170126212001.14103-4-joe@ovn.org [ Check snprintf >= for truncation, as snprintf(bf, size, ...) == size also means truncation ] Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com> |
