From 7c6090ee2a7b3315410cfc83a94c3eb057407b25 Mon Sep 17 00:00:00 2001 From: Wang Hai Date: Wed, 16 Jun 2021 12:25:34 +0800 Subject: samples/bpf: Fix the error return code of xdp_redirect's main() Fix to return a negative error code from the error handling case instead of 0, as done elsewhere in this function. If bpf_map_update_elem() failed, main() should return a negative error.
