bonding: fix a race in IGMP handling RCU conversion in IGMP code done in net-next-2.6 raised a race in __bond_resend_igmp_join_requests(). It iterates in_dev->mc_list without appropriate protection (RTNL, or read_lock on in_dev->mc_list_lock). Another cpu might delete an entry while we use it and trigger a fault.
