8b2bf0f1d7 admin: Introduce virAdmConnectSetDaemonTimeout
Use of the admin APIs to modify logging temporarily has a rather serious
deficiency when the daemon whose config is being changed is using
auto-shutdown (default with socket-activated deployments) as the
configuration is discarded if there is no client or VM/other object
blocking auto shutdown.

This API allows users to disable/postpone shutdown timeout so that the
configuration doesn't change under their hands.

c53e0c9535 virNetDaemonAutoShutdown: Allow live update of shutdown timeout
Modify the code so that calling 'virNetDaemonAutoShutdown' will update
the auto shutdown timeout also for running daemons.

This involves changing the logic when to do the update of the timer so
that it can be called from both when the daemon is not yet runnign and
when doing a live update.

d9916c3519 conf: Separate domain post parse code into domain_postparse.c
The domain post parse functions currently live in domain_conf.c
which thus grows always larger. Mimic what we've done for the
validation code and move the post parse code into a separate
file: domain_postparse.c.

I've started by moving every function with PostParse in its name
into the new file and then compile hunting for helper functions
only to move them as well.

In the end, I've moved virDomainDefPostParse symbol in
libvirt_private.syms into a new section. And while
virDomainDeviceDefPostParseOne() is made 'public' in
domain_postparse.h too, I'm not exporting it because it has no
caller outside src/conf/ and it's unlikely it ever will.

531b62950f domain_conf: Unexport virDomainDefPostParseDeviceIteratorData
The virDomainDefPostParseDeviceIteratorData struct is exported in
domain_conf.h because it's used in both domain_conf.c and
domain_validate.c. However, the latter usage is not warranted,
it's just a shortcut so that we don't have to introduce a similar
struct just for domain_validate.c. Well, do the extra step and
introduce a separate structure for domain_validate.c. This allows
us to move post parse code later on.

262672dbbf qemu_firmware: Enable loader.secure when requires-smm
Currently, a firmware configuration such as

  <os firmware='efi'>
    <firmware>
      <feature enabled='yes' name='enrolled-keys'/>
    </firmware>
  </os>

will correctly pick a firmware that implements the Secure Boot
feature and initialize the NVRAM file so that it contains the
keys necessary to enforce the signing requirements. However, the
lack of a

  <loader secure='yes'/>

element makes it possible for pflash writes to happen outside
of SMM mode. This means that the authenticated UEFI variables
where the keys are stored could potentially be overwritten by
malicious code running in the guest, thus making it possible to
circumvent Secure Boot.

To prevent that from happening, automatically turn on the
loader.secure feature whenever a firmware that implements Secure
Boot is chosen by the firmware autoselection logic. This is
identical to the way we already automatically enable SMM in such
a scenario.

Note that, while this is technically a guest-visible change, it
will not affect migration of existings VMs and will not prevent
legitimate guest code from running.

de2a338dce conf: Validate firmware configuration more thoroughly
Generally speaking, when firmware autoselection is in use we
don't want any information to be provided manually. There are
two exceptions:

  * we still want the path to the NVRAM file to be customizable;

  * using <loader secure='yes'/> was how you would ask for a
    firmware that implements the Secure Boot feature in the
    original approach to firmware autoselection, so we want to
    keep that working.

Anything else should result in a descriptive error.

421d4f1fa8 conf: Always parse all firmware information
Currently we're simply ignoring some elements and attributes,
such as the loader path, when firmware autoselection is enabled
because we know we're not going to use them.

This makes sense, but has the unfortunate consequence of
confusing users who experience part of their configuration
simply going away for no apparent reason.

A more user-friendly approach is to produce meaningful error
messages in those scenarios. As a first step towards that goal,
stop conditionally parsing information.

This combination doesn't make sense and so the firmware
autoselection logic will not be able to find a suitable firmware,
but it's more user-friendly to report a detailed error upfront.

Note that this check would ideally happen in the validate phase,
but if we moved it there we would no longer be able to
automatically enable secure-boot when enrolled-keys=yes. Since
the combination never resulted in a working configuration, the
chances of this causing real-world VMs to disappear are
extremely low.
