Resolved merge conflict with net-next. New patch shifts bpf_prog_{attach,detach}() to libbpf. Drop unnecessary build targets Drop extra unneeded log buffers v3: Add ack for first patch. Split out second patch from v2 into separate changes for remaining diff. Add patches to switch samples/bpf over to using tools/lib/. (Was "libbpf: Synchronize implementations") v2: Don't shift non-bpf code into libbpf. Drop the patch to synchronize ELF definitions with tc. v1: https://www.mail-archive.com/netdev@vger.kernel.org/msg135088.html First post. Joe Stringer (5): samples/bpf: Make samples more libbpf-centric samples/bpf: Switch over to libbpf tools lib bpf: Add bpf_prog_{attach,detach} samples/bpf: Remove perf_event_open() declaration samples/bpf: Move open_raw_sock to separate header samples/bpf/Makefile | 70 +++++---- samples/bpf/README.rst | 4 +- samples/bpf/bpf_load.c | 21 ++- samples/bpf/bpf_load.h | 3 + samples/bpf/fds_example.c | 11 +- samples/bpf/lathist_user.c | 2 +- samples/bpf/libbpf.c | 176 ---------------------- samples/bpf/libbpf.h | 28 +--- samples/bpf/lwt_len_hist_user.c | 6 +- samples/bpf/offwaketime_user.c | 8 +- samples/bpf/sampleip_user.c | 7 +- samples/bpf/sock_example.c | 14 +- samples/bpf/sock_example.h | 35 +++++ samples/bpf/sockex1_user.c | 7 +- samples/bpf/sockex2_user.c | 5 +- samples/bpf/sockex3_user.c | 5 +- samples/bpf/spintest_user.c | 8 +- samples/bpf/tc_l2_redirect_user.c | 4 +- samples/bpf/test_cgrp2_array_pin.c | 4 +- samples/bpf/test_cgrp2_attach.c | 12 +- samples/bpf/test_cgrp2_attach2.c | 8 +- samples/bpf/test_cgrp2_sock.c | 7 +- samples/bpf/test_current_task_under_cgroup_user.c | 8 +- samples/bpf/test_lru_dist.c | 32 ++-- samples/bpf/test_probe_write_user_user.c | 2 +- samples/bpf/trace_event_user.c | 23 +-- samples/bpf/trace_output_user.c | 5 +- samples/bpf/tracex2_user.c | 10 +- samples/bpf/tracex3_user.c | 4 +- samples/bpf/tracex4_user.c | 4 +- samples/bpf/tracex6_user.c | 5 +- samples/bpf/xdp1_user.c | 2 +- samples/bpf/xdp_tx_iptunnel_user.c | 6 +- tools/lib/bpf/bpf.c | 21 +++ tools/lib/bpf/bpf.h | 3 + 35 files changed, 238 insertions(+), 332 deletions(-) delete mode 100644 samples/bpf/libbpf.c create mode 100644 samples/bpf/sock_example.h -- 2.10.2
