on my machine (specs at the end) running Jammy as the host, and launching a Jammy container:
1. lxc launch ubuntu:jammy test-jammy-on-jammy from journal Oct 06 07:36:47 j5awry-sys76 kernel: audit: type=1400 audit(1696595807.223:51559): apparmor="DENIED" operation="mount" class="mount" info="failed flags match" error=-13 profile="lxd-test-jammy-on-jammy_</var/snap/lxd/common/lxd>" name="/run/systemd/unit-root/proc/" pid=723735 comm="(d-logind)" fstype="proc" srcname="proc" flags="rw, nosuid, nodev, noexec" Oct 06 07:36:47 j5awry-sys76 kernel: audit: type=1400 audit(1696595807.227:51560): apparmor="DENIED" operation="mount" class="mount" info="failed flags match" error=-13 profile="lxd-test-jammy-on-jammy_</var/snap/lxd/common/lxd>" name="/run/systemd/unit-root/tmp/" pid=723724 comm="(crub_all)" flags="rw, nosuid, remount, bind" Oct 06 07:36:47 j5awry-sys76 kernel: audit: type=1400 audit(1696595807.239:51561): apparmor="DENIED" operation="mount" class="mount" info="failed flags match" error=-13 profile="lxd-test-jammy-on-jammy_</var/snap/lxd/common/lxd>" name="/run/systemd/unit-root/proc/" pid=723750 comm="(ostnamed)" fstype="proc" srcname="proc" flags="rw, nosuid, nodev, noexec" so i get the same `mount - failed flags match` that i see above, but not the `file-inherit` denies. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/2038567 Title: Mantic 6.5.0-7 kernel causes regression in LXD container usage Status in Release Notes for Ubuntu: New Status in apparmor package in Ubuntu: New Status in linux package in Ubuntu: Incomplete Status in lxd package in Ubuntu: New Status in snapd package in Ubuntu: New Bug description: Following upgrade to 6.5.0-7 kernel in mantic cloud images we are seeing a regression in our cloud image tests. The test runs the following: ``` lxd init --auto --storage-backend dir lxc launch ubuntu-daily:mantic mantic lxc info mantic lxc exec mantic -- cloud-init status --wait ``` The `lxc exec mantic -- cloud-init status --wait` times out after 240s and will fail our test as a result. I have been able to replicate in a local VM ``` wget http://cloud-images.ubuntu.com/mantic/20231005/mantic-server-cloudimg-amd64.img wget --output-document=launch-qcow2-image-qemu.sh https://gist.githubusercontent.com/philroche/14c241c086a5730481e24178b654268f/raw/7af95cd4dfc8e1d0600e6118803d2c866765714e/gistfile1.txt chmod +x launch-qcow2-image-qemu.sh ./launch-qcow2-image-qemu.sh --password passw0rd --image ./mantic-server-cloudimg-amd64.img cat <<EOF > "./reproducer.sh" #!/bin/bash -eux lxd init --auto --storage-backend dir lxc launch ubuntu-daily:mantic mantic lxc info mantic lxc exec mantic -- cloud-init status --wait EOF chmod +x ./reproducer.sh sshpass -p passw0rd scp -o UserKnownHostsFile=/dev/null -o CheckHostIP=no -o StrictHostKeyChecking=no -P 2222 ./reproducer.sh ubuntu@127.0.0.1:~/ sshpass -p passw0rd ssh -o UserKnownHostsFile=/dev/null -o CheckHostIP=no -o StrictHostKeyChecking=no -p 2222 ubuntu@127.0.0.1 sudo apt-get update sshpass -p passw0rd ssh -o UserKnownHostsFile=/dev/null -o CheckHostIP=no -o StrictHostKeyChecking=no -p 2222 ubuntu@127.0.0.1 sudo apt-get upgrade --assume-yes sshpass -p passw0rd ssh -o UserKnownHostsFile=/dev/null -o CheckHostIP=no -o StrictHostKeyChecking=no -p 2222 ubuntu@127.0.0.1 ./reproducer.sh ``` The issue is not present with the 6.5.0-5 kernel and the issue is present regardless of the container launched. I tried the jammy container to test this. From my test VM ``` ubuntu@cloudimg:~$ uname --all Linux cloudimg 6.5.0-7-generic #7-Ubuntu SMP PREEMPT_DYNAMIC Fri Sep 29 09:14:56 UTC 2023 x86_64 x86_64 x86_64 GNU/Linux ubuntu@cloudimg:~$ uname --kernel-release 6.5.0-7-generic ``` This is a regression in our test that will block 23.10 cloud image release next week.
