Subject: [PATCHv4 net 0/3] net: sched: ife: malformed ife packet fixes

As promised at netdev 2.2 tc workshop I am working on adding scapy support for
tdc testing. It is still work in progress. I will submit the patches to tdc
later (they are not in good shape yet). The good news is I have been able to
find bugs which normal packet testing would not be able to find.
With fuzzy testing I was able to craft certain malformed packets that IFE
action was not able to deal with. This patch set fixes those bugs.

changes since v4:
 - use pskb_may_pull before pointer assign

changes since v3:
 - use pskb_may_pull

changes since v2:
 - remove inline from __ife_tlv_meta_valid
 - add const to cast to meta_tlvhdr
 - add acked and reviewed tags

Alexander Aring (3):
  net: sched: ife: signal not finding metaid
  net: sched: ife: handle malformed tlv length
  net: sched: ife: check on metadata length
