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