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