From 2062cc20d0a8e370163efccbee555347e17100c0 Mon Sep 17 00:00:00 2001 From: Dan Carpenter Date: Fri, 7 Dec 2012 01:10:46 +0000 Subject: [PATCH] bridge: make buffer larger in br_setlink() We pass IFLA_BRPORT_MAX to nla_parse_nested() so we need IFLA_BRPORT_MAX + 1 elements. Also Smatch complains that we read past the end of the array when in br_set_port_flag() when it's called with IFLA_BRPORT_FAST_LEAVE.
