Subject: ifstat: handle strdup return value
X-Git-Tag: v6.9.0~17
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=b22a3430bd17c4f75e6f113ecfeb8ea386d6b408;p=thirdparty%2Fiproute2.git

ifstat: handle strdup return value

get_nlmsg_extended is missing the check as
it's done in get_nlmsg

v2: don't set the errno value explicitly
