Share bpf_trace_printk() and bpf_get_smp_processor_id() helpers between tracing and networking. Alexei Starovoitov (3): bpf: introduce current->pid, tgid, uid, gid, comm accessors bpf: allow networking programs to use bpf_trace_printk() for debugging bpf: let kprobe programs use bpf_get_smp_processor_id() helper include/linux/bpf.h | 4 +++ include/uapi/linux/bpf.h | 19 +++++++++++++ kernel/bpf/core.c | 7 +++++ kernel/bpf/helpers.c | 58 ++++++++++++++++++++++++++++++++++++++ kernel/trace/bpf_trace.c | 28 ++++++++++++------ net/core/filter.c | 8 ++++++ samples/bpf/bpf_helpers.h | 6 ++++ samples/bpf/tracex2_kern.c | 24 ++++++++++++---- samples/bpf/tracex2_user.c | 67 ++++++++++++++++++++++++++++++++++++++------ 9 files changed, 199 insertions(+), 22 deletions(-) -- 1.7.9.5
