David Ahern 7bb387c5ab net: Allow IP_MULTICAST_IF to set index to L3 slave ... IP_MULTICAST_IF fails if sk_bound_dev_if is already set and the new index does not match it. e.g., ntpd[15381]: setsockopt IP_MULTICAST_IF 192.168.1.23 fails: Invalid argument Relax the check in setsockopt to allow setting mc_index to an L3 slave if sk_bound_dev_if points to an L3 master. Make a similar change for IPv6. In this case change the device lookup to take the rcu_read_lock avoiding a refcnt. The rcu lock is also needed for the lookup of a potential L3 master device. This really only silences a setsockopt failure since uses of mc_index are secondary to sk_bound_dev_if if it is set. In both cases, if either index is an L3 slave or master, lookups are directed to the same FIB table so relaxing the check at setsockopt time causes no harm. Patch is based on a suggested change by Darwin for a problem noted in their code base.
