[PATCH net-next 3/4] bpf: add support for persistent maps/progs

2015-10-15 Thread Daniel Borkmann
This work adds support for "persistent" eBPF maps/programs. The term "persistent" is to be understood that maps/programs have a facility that lets them survive process termination. This is desired by various eBPF subsystem users. Just to name one example: tc classifier/action. Whenever tc parses

Since we're going to use anon_inode_getfd() invocations in more than just the current places, make a helper function for both, so that we only need to pass a map/prog pointer to the helper itself in order to get a fd. The new helpers are called bpf_map_new_fd() and bpf_prog_new_fd().
