   4 Subject: [PATCH] lib/bpf: add missing limits.h includes
   5
   6 Several functions in bpf_glue.c and bpf_libbpf.c rely on PATH_MAX, which is
   7 normally included from <limits.h> in other iproute2 source files.
   8
   9 It fixes errors seen using gcc 10.2.0, binutils 2.35.1 and musl 1.1.24:
  10
  11 bpf_glue.c: In function 'get_libbpf_version':
  12 bpf_glue.c:46:11: error: 'PATH_MAX' undeclared (first use in this function);
  13 did you mean 'AF_MAX'?
  14    46 |  char buf[PATH_MAX], *s;
  15       |           ^~~~~~~~
  16       |           AF_MAX
