   4 Subject: [PATCH] wireguard: selftests: ensure non-addition of peers with
   5  failed precomputation
   6
   7 commit f9398acba6a4ae9cb98bfe4d56414d376eff8d57 upstream.
   8
   9 Ensure that peers with low order points are ignored, both in the case
  10 where we already have a device private key and in the case where we do
  11 not. This adds points that naturally give a zero output.
