dn_fib_count_nhs() could enter an infinite loop if nhp->rtnh_len == 0 (i.e. if userspace passes a malformed netlink message). Let's use the helpers from net/nexthop.h which take care of all this stuff. We can do exactly the same as e.g. fib_count_nexthops() and fib_get_nhs() from net/ipv4/fib_semantics.c. This fixes the softlockup for me. Cc: Thomas Graf <[email protected]> Signed-off-by: Vegard Nossum <[email protected]> Signed-off-by: David S. Miller <[email protected]>
