Currently we rely on rtnl locking in bond_set_rx_mode(), however it's not always the case: RTNL: assertion failed at drivers/net/bonding/bond_main.c (3391) ... [<ffffffff81651ca5>] dump_stack+0x54/0x74 [<ffffffffa029e717>] bond_set_rx_mode+0xc7/0xd0 [bonding] [<ffffffff81553af7>] __dev_set_rx_mode+0x57/0xa0 [<ffffffff81557ff8>] __dev_mc_add+0x58/0x70 [<ffffffff81558020>] dev_mc_add+0x10/0x20 [<ffffffff8161e26e>] igmp6_group_added+0x18e/0x1d0 [<ffffffff81186f76>] ? kmem_cache_alloc_trace+0x236/0x260 [<ffffffff8161f80f>] ipv6_dev_mc_inc+0x29f/0x320 [<ffffffff8161f9e7>] ipv6_sock_mc_join+0x157/0x260 ... Fix this by using RCU primitives.
