From 779994fa3636d46848edb402fe7517968e036e6f Mon Sep 17 00:00:00 2001 From: Gao Feng Date: Mon, 29 Aug 2016 18:25:28 +0800 Subject: netfilter: log: Check param to avoid overflow in nf_log_set The nf_log_set is an interface function, so it should do the strict sanity check of parameters. Convert the return value of nf_log_set as int instead of void. When the pf is invalid, return -EOPNOTSUPP.
