I'm a bit surprised that this bug doesn't get more attention, as it makes it very hard to run qemu-emulated containers of Bionic hosted on Bionic. Running such containers is a common way to cross-compile packages for foreign architectures in the absence of sufficiently powerful target HW.
The documentation on SO_PEERSEC is indeed sparse, but I do want to second Fritz in his approach. I don't see a reason, why treating the payload as incorrect and throwing it back at the application is better than handling it and saying it is not implemented (which is the case). Arguably, applications should be fixed to handle the error correctly, but I'm afraid that is a can of worms. I have encountered the same problem with systemd, apt and getent. Would the maintainers be open to an SRU request on QEMU for this? -- You received this bug notification because you are a member of qemu- devel-ml, which is subscribed to QEMU. https://bugs.launchpad.net/bugs/1823790 Title: QEMU mishandling of SO_PEERSEC forces systemd into tight loop Status in QEMU: New Bug description: While building Debian images for embedded ARM target systems I detected that QEMU seems to force newer systemd daemons into a tight loop. My setup is the following: Host machine: Ubuntu 18.04, amd64 LXD container: Debian Buster, arm64, systemd 241 QEMU: qemu-aarch64-static, 4.0.0-rc2 (custom build) and 3.1.0 (Debian 1:3.1+dfsg-7) To easily reproduce the issue I have created the following repository: https://github.com/lueschem/edi-qemu The call where systemd gets looping is the following: 2837 getsockopt(3,1,31,274891889456,274887218756,274888927920) = -1 errno=34 (Numerical result out of range) Furthermore I also verified that the issue is not related to LXD. The same behavior can be reproduced using systemd-nspawn.
