620b8ead8b src: Access hostdev->source.subsys iff VIR_DOMAIN_HOSTDEV_MODE_SUBSYS
There are few places where a virDomainHostdevDef->source.subsys
is accessed without ->mode being checked. Mind you,
virDomainHostdevDef can be also in
VIR_DOMAIN_HOSTDEV_MODE_CAPABILITIES mode.

d406caefd1 lxc_controller: Access correct union member in virLXCControllerSetupHostdevCaps()
The point of virLXCControllerSetupHostdevCaps() is to access
.caps union member of given <hostdev/> source. And it does so in
the switch, but then, when reporting an error the .subsys member
is accessed.

These originally allowed customizing the ci/Makefile script which was
the core of the local container executions. The problem was that
however flexible this may have been, it never mirrored what was being

GitLab jobs locally, these would only ever make sense to be set/used in
interactive shell container sessions where the developer is perfectly
capable of using the right meson/ninja CLI options directly without
going through another shell variable indirection as it was the case

04b9118fe5 ci: helper: Rework _lcitool_run method logic
This method wasn't even utilized before this patch. This patch adds all
the necessary logic to successfully execute a container workload via
lcitool (which will later allow us to ditch ci/Makefile). Because
container executions via lcitool creates the following inside the
container:

    $ ls
    script datadir

where 'datadir' is the workload directory (in this case a local git
repo clone) and 'script' is the code that runs whatever the workload is
over 'datadir'.

In order to satisfy the ^above, our helper generates a trivial
temporary 'script' that will source ci/build.sh and run whatever was
specified as --job essentially to simulate the exact steps a GitLab
pipeline job would go through.

This would normally be not needed at all, but the problem here is the
Shell-in-YAML which GitLab interprets. It outputs every command that

easy identification of problems. Well, that useful feature is lost when
there's indirection and one script calls into another in which case it
would only output the respective script name which would make failure
investigation harder. This simple helper tackles that by echoing the
command to be run by any script/function with a color escape sequence
so that we don't lose track of the *actual* shell commands being run as
part of the GitLab job pipelines. An example of what the output then
might look like:

3222c9ca67 lxc_container: Check retval of capng_get_caps_process()
Added in v0.6.5~14 the call to capng_get_caps_process() inside of
lxcContainerDropCapabilities() is not really explained in the
commit message. But looking into the libcap-ng sources it's to
initialize the internal state of the library.

But with recent libcap-ng commit [1] (which some bleeding edge
distros - like Fedora rawhide - already picked up) the function
has been marked as 'warn unused result'. Well, check for its
retval then.

16ad37c119 virnetdevopenvswitch: Propagate OVS error messages
When configuring OVS interfaces/bridges we spawn 'ovs-vsctl' with
appropriate arguments and if it exited with a non-zero status we
report a generic error message, like "Unable to add port vnet0 to
OVS bridge ovsbr0". This is all cool, but the real reason why
operation failed is hidden in (debug) logs because that's where
virCommandRun() reports it unless caller requested otherwise.

This is a bit clumsy because then we have to ask users to turn on
debug logs and reproduce the problem again, e.g. [1].

Therefore, in cases where an error is reported to the user - just
read ovs-vsctl's stderr and include it in the error message. For
other cases (like VIR_DEBUG/VIR_WARN) - well they are meant to
end up in (debug) logs anyway.
