From 5d4e3443287b28a6e9c3436adbadba2497880bd1 Mon Sep 17 00:00:00 2001 From: Chenbo Feng Date: Wed, 26 Apr 2017 16:41:23 -0700 Subject: [PATCH] bpf: Fix inaccurate helper function description The description inside uapi/linux/bpf.h about bpf_get_socket_uid helper function is no longer valid. It returns overflowuid rather than 0 when failed. Signed-off-by: Chenbo Feng Acked-by: Daniel Borkmann Acked-by: Alexei Starovoitov Signed-off-by: David S.
