Hello All,We are trying to implement L2 forwarding in xdp and we need to convert the mac-address to a hash value. Thus far, we have tried using crc32 functions from <linux/crc32.h> for kernel space but it can't be used in user space. We need a common crc hash function for both kernel and user space.
The kernel crc function causes the following error: invalid relo for insn[24].code 0x85 bpf_load_program() err=22 0: (61) r2 = *(u32 *)(r1 +4) 1: (61) r1 = *(u32 *)(r1 +0) . . . 23: (b7) r3 = 6 24: (85) call unknown#-1 BPF_CALL uses reserved fields Can you please point to some examples or references? We would be highly grateful. Thanks, Sincerely,
