| H A D | relo_core.c | diff 29db4bea1d10b73749d7992c1fc9ac13499e8871 Wed Dec 01 19:10:26 CET 2021 Alexei Starovoitov <ast@kernel.org> bpf: Prepare relo_core.c for kernel duty.
Make relo_core.c to be compiled for the kernel and for user space libbpf.
Note the patch is reducing BPF_CORE_SPEC_MAX_LEN from 64 to 32.
This is the maximum number of nested structs and arrays.
For example:
struct sample {
int a;
struct {
int b[10];
};
};
struct sample *s = ...;
int *y = &s->b[5];
This field access is encoded as "0:1:0:5" and spec len is 4.
The follow up patch might bump it back to 64.
