[Bug 1922010] Re: [Ubuntu 21.04] IBM Z go binary crashes under Qemu
Hi Andreas, yes, that is what we believe, too - thx for confirming.

[Bug 1922010] Re: [Ubuntu 21.04] IBM Z go binary crashes under Qemu
Since it is upstream, can be reproduced (by you more easily than me) it makes sense. I got no issues with the PPA running other things and a review on the MP. So I uploaded this to Hirsute hoping that it will still slip in before release. But looking for an SRU I wonder how real the case is if it is so complex to trigger. It only affects groovy users (not happening on Focal as you said) - so the "can't upgrade from an LTS" argument does not apply here either. So for now I'd think the SRUs are a "Won't Fix", but I can be convinced if you think it really is important. If you then would have simpler or more use cases to make that argument that would be helpful to later also convince the SRU Team. ** Changed in: qemu (Ubuntu Groovy) Status: Triaged => Won't Fix ** Changed in: qemu (Ubuntu Hirsute) Status: Triaged => In Progress ** Changed in: qemu (Ubuntu Hirsute) Status: In Progress => Fix Committed -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1922010 Title: [Ubuntu 21.04] IBM Z go binary crashes under Qemu To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu-z-systems/+bug/1922010/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

I tried to use it the same way I'd do arm@x86 but that failed. Maybe you can share what environment you used bfore I start wasting time to reproduce this. And OTOH if this really only hits such a case it might be too edge-case for an SRU anyway. Then I'd even more appreciate a fast response to get it at least into Hirsute before it fully closes. # not working WIP repro state $ sudo su - $ apt install qemu-user-static debootstrap schroot $ sudo qemu-debootstrap --arch=s390x hirsute s390x-ubuntu $ cat > /etc/schroot/chroot.d/s390x-ubuntu << EOF [s390x-ubuntu] type=directory description=Ubuntu 21.04 Hirsute (s390x) directory=$(pwd)/s390x-ubuntu root-users=$(whoami) root-groups=$(whoami) users=$(whoami) groups=$(whoami) EOF $ schroot -c s390x-ubuntu Obviously, if you'd have any static executable we could throw at qemu- s390x-static that would simplify things a lot. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1922010 Title: [Ubuntu 21.04] IBM Z go binary crashes under Qemu To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu-z-systems/+bug/1922010/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 1922010] Re: [Ubuntu 21.04] IBM Z go binary crashes under Qemu
Hmm, no I get the same output with the new qemu version. Direct /usr/bin/go works fine I did use qemu-s390x-static on s390x, it didn't have to do a lot of emulation. Is this only a problem to "real" emulation through qemu-user-static e.g. when using qemu-s390x-static on x86? If so which environment/debootstrap/... did you use to have the s390x go that you execute? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1922010 Title: [Ubuntu 21.04] IBM Z go binary crashes under Qemu To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu-z-systems/+bug/1922010/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Thanks for the Report! That is: commit 23fff7a17f47420797ac6480147941612152a9ad Author: Andreas Krebbel Date: Wed Mar 24 19:51:28 2021 +0100 linux-user/s390x: Use the guest pointer for the sigreturn stub When setting up the pointer for the sigreturn stub in the return address register (r14) we currently use the host frame address instead of the guest frame address. Note: This only caused problems if Qemu has been built with --disable-pie (as it is in distros nowadays). Otherwise guest_base defaults to 0 hiding the actual problem.
