David S. Miller 44ef976ab3 Merge git://git.kernel.org/pub/scm/linux/kernel/git/bpf/bpf-next ... Daniel Borkmann says: ==================== pull-request: bpf-next 2020-03-13 The following pull-request contains BPF updates for your *net-next* tree. We've added 86 non-merge commits during the last 12 day(s) which contain a total of 107 files changed, 5771 insertions(+), 1700 deletions(-). The main changes are: 1) Add modify_return attach type which allows to attach to a function via BPF trampoline and is run after the fentry and before the fexit programs and can pass a return code to the original caller, from KP Singh. 2) Generalize BPF's kallsyms handling and add BPF trampoline and dispatcher objects to be visible in /proc/kallsyms so they can be annotated in stack traces, from Jiri Olsa. 3) Extend BPF sockmap to allow for UDP next to existing TCP support in order in order to enable this for BPF based socket dispatch, from Lorenz Bauer. 4) Introduce a new bpftool 'prog profile' command which attaches to existing BPF programs via fentry and fexit hooks and reads out hardware counters during that period, from Song Liu. Example usage: bpftool prog profile id 337 duration 3 cycles instructions llc_misses 4228 run_cnt 3403698 cycles (84.08%) 3525294 instructions # 1.04 insn per cycle (84.05%) 13 llc_misses # 3.69 LLC misses per million isns (83.50%) 5) Batch of improvements to libbpf, bpftool and BPF selftests. Also addition of a new bpf_link abstraction to keep in particular BPF tracing programs attached even when the applicaion owning them exits, from Andrii Nakryiko. 6) New bpf_get_current_pid_tgid() helper for tracing to perform PID filtering and which returns the PID as seen by the init namespace, from Carlos Neira. 7) Refactor of RISC-V JIT code to move out common pieces and addition of a new RV32G BPF JIT compiler, from Luke Nelson. 8) Add gso_size context member to __sk_buff in order to be able to know whether a given skb is GSO or not, from Willem de Bruijn. 9) Add a new bpf_xdp_output() helper which reuses XDP's existing perf RB output implementation but can be called from tracepoint programs, from Eelco Chaudron. ==================== Signed-off-by: David S.
