Hi Dave, Hopefully these are the last fixes for 5.7:
1) A trivial bump in the selftest harness to support gcc-10. build.wireguard.com is still on gcc-9 but I'll probably switch to gcc-10 in the coming weeks. 2) A concurrency fix regarding userspace modifying the pre-shared key at the same time as packets are being processed, reported by Matt Dunwoodie. 3) We were previously clearing skb->hash on egress, which broke fq_codel, cake, and other things that actually make use of the flow hash for queueing, reported by Dave Taht and Toke Høiland-Jørgensen. 4) A fix for the increased memory usage caused by (3). This can be thought of as part of patch (3), but because of the separate reasoning and breadth of it I thought made it a bit cleaner to put in a standalone commit. Fixes (2), (3), and (4) are -stable material. Thanks, Jason Jason A.
