[batman-adv] maint: batman-adv: Fix multicast packet loss with a single WANT_ALL_IPV4/6 flag (edba00d)

by postmaster＠open-mesh.org

Repository : ssh://git@open-mesh.org/batman-adv On branch : maint >--------------------------------------------------------------- commit edba00d56efb1d55cdd40957e010fba80580b5e2 Author: Linus Lüssing <linus.luessing(a)c0d3.blue> Date: Sun Mar 4 13:08:17 2018 +0100 batman-adv: Fix multicast packet loss with a single WANT_ALL_IPV4/6 flag As the kernel doc describes too the code is supposed to skip adding multicast TT entries if both the WANT_ALL_IPV4 and WANT_ALL_IPV6 flags are present. Unfortunately, the current code even skips adding multicast TT entries if only either the WANT_ALL_IPV4 or WANT_ALL_IPV6 is present. This could lead to IPv6 multicast packet loss if only an IGMP but not an MLD querier is present for instance or vice versa.
