Chris Leech fa06883281 libfc: sanity check cpu number extracted from xid ... In the receive path libfc extracts a cpu number from the ox_id in the fiber channel header and uses that to do a per_cpu_ptr conversion. If, for some reason, a frame is received with an invalid ox_id, per_cpu_ptr will return an invalid pointer and the libfc receive path will panic the system trying to use it. I'm currently looking at such a case, and I don't yet know why a cpu number > nr_cpu_ids is appearing in an exchange id. But adding a sanity check in libfc prevents a system panic, and seems like good idea when dealing with frames coming in from the network.
