In the Linux kernel, the following vulnerability has been resolved:
bonding: prevent potential infinite loop in bond_header_parse()
bond_header_parse() can loop if a stack of two bonding devices is setup,
because skb->dev always points to the hierarchy top.
Add new "const struct net_device *dev" parameter to
(struct header_ops)->parse() method to make sure the recursion
is bounded, and that the final leaf parse method is called.
