Subject: [PATCH 5.10 367/593] samples/bpf: Fix the error return code of xdp_redirects main()
From: Wang Hai <wanghai38@...wei.com>
[ Upstream commit 7c6090ee2a7b3315410cfc83a94c3eb057407b25 ]
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.
Fixes: 832622e6bd18 ("xdp: sample program for new bpf_redirect helper")
