bpf: samples: Do not touch RLIMIT_MEMLOCK

2020-12-03T02:32:47+00:00

Since bpf is not using rlimit memlock for the memory accounting
and control, do not change the limit in sample applications.

samples: bpf: Refactor tracepoint tracing programs with libbpf

2020-08-25T03:59:35+00:00

For the problem of increasing fragmentation of the bpf loader programs,
instead of using bpf_loader.o, which is used in samples/bpf, this
commit refactors the existing tracepoint tracing programs with libbbpf
bpf loader.

    - Adding a tracepoint event and attaching a bpf program to it was done
    through bpf_program_attach().
    - Instead of using the existing BPF MAP definition, MAP definition
    has been refactored with the new BTF-defined MAP format.

samples: bpf: include bpf/bpf.h instead of local libbpf.h

2018-05-15T05:52:10+00:00

There are two files in the tree called libbpf.h which is becoming
problematic.  Most samples don't actually need the local libbpf.h
they simply include it to get to bpf/bpf.h.  Include bpf/bpf.h
directly instead.
