ipv4: Do not use dead fib_info entries. Due to RCU lookups and RCU based release, fib_info objects can be found during lookup which have fi->fib_dead set. We must ignore these entries, otherwise we risk dereferencing the parts of the entry which are being torn down. Reported-by: Yevgen Pronenko <yevgen.pronenko@sonymobile.com> Signed-off-by: David S.
