net: ipv6: Fix UDP early demux lookup with udp_l3mdev_accept=0
David Ahern reported that 5425077d ("net: ipv6: Add early demux handler for UDP unicast") breaks udp_l3mdev_accept=0 since early demux for IPv6 UDP was doing a generic socket lookup which does not require an exact match. Fix this by making UDPv6 early demux match connected sockets only. v1->v2: Take reference to socket after match as suggested by Eric v2->v3: Add comment before break Fixes: 5425077d ("net: ipv6: Add early demux handler for UDP unicast") Reported-by:David Ahern <dsa@cumulusnetworks.com> Signed-off-by:
