X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=b6d85cf5bd1433c5dd6bf6bb3a176537184c630c;p=linux.git

net/ipv6: Initialise msg_control_is_user

do_ipv6_setsockopt() makes use of struct msghdr::msg_control in the
IPV6_2292PKTOPTIONS case. Make sure to initialise
msg_control_is_user accordingly.
