    bpf: sockmap sample use clang flag, -target bpf · 4dfe1bb9
    John Fastabend 提交于
    Per Documentation/bpf/bpf_devel_QA.txt add the -target flag to the
    sockmap Makefile. Relevant text quoted here,
    
       Otherwise, you can use bpf target. Additionally, you _must_ use
       bpf target when:
    
     - Your program uses data structures with pointer or long / unsigned
       long types that interface with BPF helpers or context data
       structures. Access into these structures is verified by the BPF
       verifier and may result in verification failures if the native
       architecture is not aligned with the BPF architecture, e.g. 64-bit.
       An example of this is BPF_PROG_TYPE_SK_MSG require '-target bpf'
