[Patch net] ipv6: check for ip6_null_entry in __ip6_del_rt_siblings()

Andrey reported a NULL pointer deref bug in ipv6_route_ioctl() -> ip6_route_del() -> __ip6_del_rt_siblings() code path. This is because ip6_null_entry is returned in this path since ip6_null_entry is kinda default for a ipv6 route table root node. Quote from David Ahern: ip6_null_entry is the

[PATCH] net: bridge: allow IPv6 when multicast flood is disabled

Even with multicast flooding turned off, IPv6 ND should still work so that IPv6 connectivity is provided. Allow this by continuing to flood multicast traffic originated by us. And similar to the unicast case, set auto-mask if the multicast flood flag is set. Fixes: b6cb5ac8331b ("net: bridge: add
