Subject: netfilter: ipset: add missing break statemtns in ip_set_get_ip_port()
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=316ed388802533bcfd3dffb38d2ba29ac5428456;p=linux-beck.git

netfilter: ipset: add missing break statemtns in ip_set_get_ip_port()

Don't fall through in the switch statement, otherwise IPv4 headers
are incorrectly parsed again as IPv6 and the return value will always
be 'false'.
