Hello,

A new version, v1.0.20200520, of the backported WireGuard kernel module for
3.10 <= Linux <= 5.5.y has been tagged in the git repository.

== Changes ==

  This release aligns with the changes I sent to DaveM for 5.7-rc7 and were
  pushed to net.git about 45 minutes ago.
  
  * qemu: use newer iproute2 for gcc-10
  * qemu: add -fcommon for compiling ping with gcc-10
  
  These enable the test suite to compile with gcc-10.
  
  * noise: read preshared key while taking lock
  
  Matt noticed a benign data race when porting the Linux code to OpenBSD.
  
  * queueing: preserve flow hash across packet scrubbing
  * noise: separate receive counter from send counter
  
  WireGuard now works with fq_codel, cake, and other qdiscs that make use of
  skb->hash. This should significantly improve latency spikes related to
  buffer bloat. Here's a before and after graph from some data Toke measured:
  https://data.zx2c4.com/removal-of-buffer-bloat-in-wireguard.png
  
  * compat: support RHEL 8 as 8.2, drop 8.1 support
  * compat: support CentOS 8 explicitly
  * compat: RHEL7 backported the skb hash renamings
  
  The usual RHEL churn.
  
  * compat: backport renamed/missing skb hash members
  
  The new support for fq_codel and friends meant more backporting work.
  
  * compat: ip6_dst_lookup_flow was backported to 4.14, 4.9, and 4.4
  
  The main motivation for releasing this now: three stable kernels were released
  at the same time, with a patch that necessitated updating in our compat layer.
