Package: qemu-user Version: 1:10.0.8+ds-0+deb13u1 Severity: important X-Debbugs-Cc: [email protected] User: [email protected] Usertags: arm64
The cloud team user qemu-user to emulate various non-amd64 architectures to build images for those architectures on amd64 hosts. We generate images for all stable Debian releases including LTS, as well as sid and testing. We build for all supported releases for all architectures and supported cloud environments each day. Builds are performed in trixie VMs. We have observed a scenario in which qemu segfaults when running ldconfig in an arm64 chroot during the debootstrap process of the image build. We have a bit more context in a gitlab issue at https://salsa.debian.org/cloud-team/debian-cloud-images/-/work_items/97 The problem can be reproduced on a trixie amd64 system with: $ sudo debootstrap --verbose --variant minbase --arch arm64 bullseye bullseye-rootfs https://deb.debian.org/debian $ sudo chroot bullseye-rootfs /usr/bin/bash -c 'declare -i count=0; while ldconfig && [ $count -lt 1000 ]; do count+=1; done ; echo "Done after $count iterations"' The problem appears to only be triggered by bullseye's ldconfig. I have not been able to reproduce it with newer versions. The problem does not occur with every ldconfig invocation, as you can see with: root@fai-test:~# declare -i count=0; while ldconfig; do count+=1; done; echo "Done after $count iterations" qemu: uncaught target signal 11 (Segmentation fault) - core dumped Segmentation fault Done after 71 iterations root@fai-test:~# declare -i count=0; while ldconfig; do count+=1; done; echo "Done after $count iterations" qemu: uncaught target signal 11 (Segmentation fault) - core dumped Segmentation fault Done after 99 iterations root@fai-test:~# declare -i count=0; while ldconfig; do count+=1; done; echo "Done after $count iterations" qemu: uncaught target signal 11 (Segmentation fault) - core dumped Segmentation fault Done after 23 iterations root@fai-test:~# declare -i count=0; while ldconfig; do count+=1; done; echo "Done after $count iterations" qemu: uncaught target signal 11 (Segmentation fault) - core dumped Segmentation fault Done after 41 iterations Thanks noah
