The idea is to make the device translator run at\nthe program load time. This makes the offload more explicit to\nthe user space. It also makes it easy for the device translator\nto insert information into the original verifier log.\n\nv2:\n - include linux/bug.h instead of asm/bug.h;\n - rebased on top of Craig's verifier fix (no changes, the last patch\n just removes more code now). I checked the set doesn't conflict \n with Jiri's, Josef's or Roman's patches, but missed Craig's fix :(\nv1:\n - rename the ifindex member on load;\n - improve commit messages;\n - split nfp patches more.\n\nJakub Kicinski (15):\n net: bpf: rename ndo_xdp to ndo_bpf\n bpf: offload: add infrastructure for loading programs for a specific\n netdev\n bpf: report offload info to user space\n bpftool: print program device bound info\n xdp: allow attaching programs loaded for specific device\n cls_bpf: allow attaching programs loaded for specific device\n nfp: bpf: drop support for cls_bpf with legacy actions\n nfp: bpf: remove the register renumbering leftovers\n nfp: bpf: remove unnecessary include of nfp_net.h\n nfp: bpf: refactor offload logic\n nfp: bpf: require seamless reload for program replace\n nfp: bpf: move program prepare and free into offload.c\n nfp: bpf: move translation prepare to offload.c\n nfp: bpf: move to new BPF program offload infrastructure\n bpf: remove old offload/analyzer\n\n drivers/net/ethernet/broadcom/bnxt/bnxt.c | 2 +-\n drivers/net/ethernet/broadcom/bnxt/bnxt_xdp.c | 2 +-\n drivers/net/ethernet/broadcom/bnxt/bnxt_xdp.h | 2 +-\n drivers/net/ethernet/cavium/thunder/nicvf_main.c | 4 +-\n drivers/net/ethernet/intel/i40e/i40e_main.c | 6 +-\n drivers/net/ethernet/intel/ixgbe/ixgbe_main.c | 4 +-\n drivers/net/ethernet/mellanox/mlx4/en_netdev.c | 6 +-\n drivers/net/ethernet/mellanox/mlx5/core/en_main.c | 4 +-\n drivers/net/ethernet/netronome/nfp/bpf/jit.c | 194 ++------------\n drivers/net/ethernet/netronome/nfp/bpf/main.c | 87 +++----\n drivers/net/ethernet/netronome/nfp/bpf/main.h | 59 ++---\n drivers/net/ethernet/netronome/nfp/bpf/offload.c | 282 +++++++++------------\n drivers/net/ethernet/netronome/nfp/bpf/verifier.c | 54 +---\n drivers/net/ethernet/netronome/nfp/nfp_app.h | 37 +++\n drivers/net/ethernet/netronome/nfp/nfp_net.h | 2 -\n .../net/ethernet/netronome/nfp/nfp_net_common.c | 12 +-\n drivers/net/ethernet/qlogic/qede/qede.h | 2 +-\n drivers/net/ethernet/qlogic/qede/qede_filter.c | 2 +-\n drivers/net/ethernet/qlogic/qede/qede_main.c | 4 +-\n drivers/net/tun.c | 4 +-\n drivers/net/virtio_net.c | 4 +-\n include/linux/bpf.h | 47 ++++\n include/linux/bpf_verifier.h | 13 +-\n include/linux/netdevice.h | 37 ++-\n include/uapi/linux/bpf.h | 7 +\n kernel/bpf/Makefile | 1 +\n kernel/bpf/core.c | 10 +-\n kernel/bpf/offload.c | 194 ++++++++++++++\n kernel/bpf/syscall.c | 52 +++-\n kernel/bpf/verifier.c | 84 +-----\n net/core/dev.c | 40 +--\n net/core/filter.c | 42 ---\n net/core/rtnetlink.c | 4 +-\n net/sched/cls_bpf.c | 10 +-\n tools/bpf/bpftool/prog.c | 31 +++\n tools/include/uapi/linux/bpf.h | 7 +\n 36 files changed, 686 insertions(+), 666 deletions(-)\n create mode 100644 kernel/bpf/offload.c" }
