Hash: SHA256

Hello,

A new version, v1.0.20210219, of the backported WireGuard kernel module for
3.10 <= Linux <= 5.5.y has been tagged in the git repository.

== Changes ==

  * compat: remove unused version.h headers
  * compat: redefine version constants for sublevel>=256
  * compat: skb_mark_not_on_list will be backported to Ubuntu 18.04
  * compat: zero out skb->cb before icmp
  
  Various compat fixes, most notable of which is that the 4.9.256 and 4.4.256
  kernels no longer cause integer wraparound problems. For more info:
  https://lwn.net/Articles/845120/ https://lwn.net/Articles/845207/
  
  * selftests: test multiple parallel streams
  * qemu: bump default kernel version
  
  Usual test harness improvements.
  
  * peer: put frequently used members above cache lines
  * device: do not generate ICMP for non-IP packets
  * queueing: get rid of per-peer ring buffers
  
  Most notable here is the queueing commit. Having two ring buffers per-peer
  means that every peer resulted in two massive ring allocations. On an 8-core
  x86_64 machine, this commit reduces the per-peer allocation from 18,688 bytes
  to 1,856 bytes, which is an 90% reduction. With some single-machine
  deployments approaching 500,000 peers, we're talking about a reduction from 7
  gigs of memory down to 700 megs of memory.

This release contains commits from: Jason A. Donenfeld and Thadeu Lima de 
Souza Cascardo.
