[Bug 1893040] Re: External modules retreval using Go1.15 on s390x appears to have checksum and ECDSA verification issues

[David Hildenbrand]

I remember we had these "ECDSA verification failure" issues in older
QEMU versions, but these were fixed.

I just tired building the go file under Fedora 32 running under latest
upstream qemu-system-s390x, and using latest go binaries from
https://golang.org/dl/:

[root@atomic-00 hello]# uname -a
Linux atomic-00 5.8.11-200.fc32.s390x #1 SMP Wed Sep 23 13:36:15 UTC 2020 s390x 
s390x s390x GNU/Linux

[root@atomic-00 hello]# go version
go version go1.15.7 linux/s390x

[root@atomic-00 hello]# go build
go: downloading rsc.io/quote v1.5.2
go: downloading rsc.io/sampler v1.3.0
go: downloading golang.org/x/text v0.0.0-20170915032832-14c0d48ead0c

[root@atomic-00 hello]# ./hello 
Hello, world.

Can you double check that you are really using latest upstream QEMU in
your more-advanced cross-build?

Title:
   External modules retreval using Go1.15 on s390x appears to have
  checksum and ECDSA verification issues

Status in QEMU:
  New

Bug description:
  We are observing issue while building go-runner image and we suspect it is 
due to QEMU version being used. As referred in below issue:
  https://github.com/golang/go/issues/40949

  We tried to build go-runner image using go1.15 and register QEMU
  (docker run --rm --privileged multiarch/qemu-user-
  static@sha256:c772ee1965aa0be9915ee1b018a0dd92ea361b4fa1bcab5bbc033517749b2af4
  --reset -p yes) as mentioned in PR
  https://github.com/kubernetes/release/pull/1499. We observed below
  failure during build:
