[OpenWrt-Devel] [PATCH] [19.07] wireguard: bump to 1.0.20200611

[Stijn Segers]

This bump fixes breakage introduced by kernel commit 8ab8786f78c3fc930f9abf6d6d85e95567de4e1f,
which is part of the 4.14.181 kernel bump, and backported ip6_dst_lookup_flow to 4.14.
This breaks the older WireGuard version currently in 19.07.

For reference, the compilation error is the one below:

build_dir/target-x86_64_musl/linux-x86_64/wireguard-linux-compat-1.0.20200506/src/compat/compat.h:104:42: error: 'const struct ipv6_stub' has no member named 'ipv6_dst_lookup'; did you mean 'ipv6_dst_lookup_flow'?
 #define ipv6_dst_lookup_flow(a, b, c, d) ipv6_dst_lookup(a, b, &dst, c) + (void *)0 ?: dst

Changelogs below taken from the official release announcements.

== Changes since v1.0.20200506 ==

  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


== Changes since v1.0.20200611 ==

  * qemu: always use cbuild gcc rather than system gcc
  * qemu: remove -Werror in order to build ancient kernels better
  * qemu: patch kernels that rely on ancient make
  * qemu: force 2MB pages for binutils 2.31
  * qemu: use cbuild gcc for avx512 exclusion
  * qemu: add extra fill in idt handler for newer binutils
  * qemu: support fetching kernels for arbitrary URLs
  * qemu: patch in UTS_UBUNTU_RELEASE_ABI for Ubuntu detection
  * qemu: work around broken centos8 kernel
  * qemu: mark per_cpu_load_addr as static for gcc-10
  
  Our qemu test suite can now handle more kernels and more compilers. Scroll
  down to the bottom of https://www.wireguard.com/build-status/ to see the
  expanded array of kernels we now test against, including some distro kernels.
  
  * compat: widen breadth of integer constants
  * compat: widen breadth of memzero_explicit backport
  * compat: backport skb_scrub_packet to 3.11
  * compat: widen breadth of prandom_u32_max backport
  * compat: narrow the breadth of iptunnel_xmit backport
  * compat: backport iptunnel_xmit to 3.11
  
  With the expanded qemu test suite, it was possible to expand our list of
  mainline kernels, so the backport compat layer is now more precise.
  
  * compat: ubuntu appears to have backported ipv6_dst_lookup_flow
  * compat: bionic-hwe-5.0/disco kernel backported skb_reset_redirect and ipv6 flow
  
  Ubuntu kernels changed recently, so this ensures we can compile with the
  latest Ubuntu releases.
  
  * compat: remove stale suse support

4.14.184 hasn't made its way into openwrt-19.07 yet but I bumped into this
ip6_dst_lookup_flow issue with the .184 bump in Koen's tree.
