== SRU Justification ==

Impact: adding a tc filter sometimes fails, potentially followed by kernel hangs and kernel NULL pointer dereference (CVE 2017-7979)

Fix: cherry-pick fix from v4.11-rc8

Regression Potential: clean cherry-picks from upstream

Wei Yongjun (1):
  net_sched: nla_memdup_cookie() can be static

Wolfgang Bumiller (1):
  net sched actions: allocate act cookie early
