+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
