[XEN PATCH v1 6/6] CI: Run the builds and tests that use the Debian 12 containers as a normal user
Posted by Javi Merino 1 month, 1 week ago
Use FF_DISABLE_UMASK_FOR_DOCKER_EXECUTOR so that GitLab CI clones xen
using the user in the image, instead of as root[0].

In qemu-smoke-dom0*.sh and qemu-alpine-x86_64.sh, use fakeroot to
create the rootfs images that untar a tarball that create character
devices.  cpio replicates the block and character devices, as well as
preserving the uid and gid it sees in the current directory.  fakeroot
lets tar think that it is creating block and character devices, and
all files are owned by root, but it is all smokes and mirrors for
cpio.

Regarding building the rootfs, I have chosen to use a fakeroot
subshell for the entire process.  automation/scripts/qubes-x86-64.sh
takes a different approach, it just uses fakeroot for the tar/cpio
commands.  I prefer to do it this way but I am happy to be overridden
if `fakeroot -s ../save tar` and `fakeroot -i ../save cpio` are
preferred.

This breaks the xilinx hardware jobs both arm and x86 as they
require root inside the container at the moment

I admit I am not a fan of this as it makes the script harder to read.
Given that almost everything on this script and similar scripts is
better run as root because it is all about repackaging cpio archivies,
instead I would do this:

diff --git a/automation/scripts/qemu-alpine-x86_64.sh b/automation/scripts/qemu-alpine-x86_64.sh
index 2660403ab2..7c0ec01e05 100755
--- a/automation/scripts/qemu-alpine-x86_64.sh
+++ b/automation/scripts/qemu-alpine-x86_64.sh
@@ -1,4 +1,4 @@
-#!/bin/bash
+#!/usr/bin/fakeroot
 
 set -ex -o pipefail
 

Keeping in mind that anyone could push a branch without fakeroot to
their personal tree triggering a gitlab-ci pipeline, the advantage of
using fakeroot would be if we force the container execution envinronment
(gitlab runner) to run containers as user. This is not currently the
configuration we have. As of now, it doesn't bring an advantage.

Given that the gitlab runners are in flux at the moment, and that this
patch cannot work with the xilinx runners, I would ask you to please
hold on on this patch until the gitlab runners are settled (~1 month).

Running the entire script as a fakeroot subshell is ugly and not
necessary.

A better fix is what I suggested under the commit message, which is
also what the qubes containers do:

Similar for the dom0 and dom0less scripts and for the xilinx scripts.

Ok, I will hold the patch.  I will also fix the xilinx scripts.
