More than one person has asked about 'why call fu_plugin_update() for a
reinstall or downgrade' and I didn't have a very good answer.
The plugin API is not officially stable, and we should fix things to be
less confusing. Use the same verbs as the FuDevice vfuncs instead.
There is a lot of code in fwupd that just assigns a shared object type to
a FuPlugin, and then for each device on that plugin assigns that same shared
object to each FuDevice.
Rather than proxy several kinds of information stores over two different levels
of abstraction create a 'context' which contains the shared *system* state
between the daemon, the plugins and the daemon.
This will allow us to hold other per-machine state in the future, for instance
the system battery level or AC state.
There are now two 'backends' of device plug/unplug events, and there is about
to become three. Rather than just adding two more vfuncs for every backend type
define common ones that all providers can use.
Also fix up the existing in-tree plugins to use the new vfunc names and filter
on the correct GType.
If the device is not authorized, it may cause a composite update that it's part
of to not behave properly.
If device is authorized at runtime, add updatable flag at runtime as well
See #2374 for more details
Thunderbolt images brought in from the SPI don't have a FARB header.
Thunderbolt update images do.
So these two types of images need to be handled separately from the
firmware parser.
Remove it's references to it's own GUdevclient and instead use
FuUdevDevice.
Some intentional casualties of the move:
* Plugin metadata around native and safe mode dropped.
- These haven't been useful in debugging anything and aren't relevant
on new hardware
* Extra GUID for 2 host controllers in same system dropped
- Although this was normally static information BIOS operations like
turning off PCI-E SD card reader or LAN controller changed things.
* The NVM version is parsed directly instead of through gudev to prevent
cached data breaking change events.
Remaining TODO:
* Force power w/ thunderbolt-power doesn't work
We don't actually need either of the things it provides (looking up in source
and built, and converting to an absolute path) so just replace it with
g_build_filename() instead.
This also has the advantage that it does the right thing on Windows.
It wasn't hugely clear what the platform ID was actually meant to represent. In
some cases it was being used like a physical ID, in others it was a logical ID,
and in others it was both. In some cases it was even used as a sysfs path.
Clear up all the confusion by splitting the platform ID into two parts, an
optional *physical* ID to represent the electrical connection, and an optional
*logical* ID to disambiguate composite devices with the same physical ID.
Also create an explicit sysfs_path getter for FuUdevDevice to make this clear.
This allows WAIT_FOR_REPLUG to always work, rather than depending on the order
that the GUIDs were added, and that the kernel would always return the same
sysfs path (which it doesn't have to do, especially for hidraw devices).
Currently we only parse the nvm_version attribute according fwupd
expectations when the device is initially added. Elsewhere we just use
the raw version as is which might be problematic as the version format
can change in the middle (for example "33.02" vs. "33.2"). Fix this so
that fu_plugin_thunderbolt_udev_get_version () always returns parsed
version string.
Update self tests accordingly to have "parsed" version to which we
compare against.

There are a lot of hacks here;
* Pulling newer libappstream-glib from Fedora
* Pulling a systemd backport
* Manually installing pillow and pygobject
* PKCS7 is turned off (gnutls is too old)
GLib creates two static inline functions for paramaters that may
not be used that set off warnings in clang but not gcc.
Ignore these on clang builds everywhere that
G_DEFINE_AUTOPTR_CLEANUP_FUNC is used.
It's actually less scary to see a SHA1 hash than it is to see a path like
/sys/devices/pci0000:00/0000:00:1d.0/usb1/1-1/1-1.2. It's also way easier to
copy and paste into the various fwupdmgr command that require a device ID and
also means we can match a partial prefix much like git allows.
If we also move to a model where plugins can be changed during different stages
of the update (e.g. during detach) then the device might change connection type
and then the sysfs path not only becomes difficult to paste, but incorrect.
Session software doesn't care about the format of the device ID (it is supposed
to be an implementation detail) and so there's no API or ABI break here. A few
plugins also needed to be ported, but nothing too worrying.
umockdev 0.9.4 changed how to test for running in mock and this
causes the assumptions on mock testing at init to fail.
Move the test for this to after the environment has been set up.
Thunderbolt has a new kernel interface starting from version 4.13,
which simplifies updating the host controller and devices: the
kernel now exposes a sysfs interface for the non-volatile memory
as a device node. This can be used to write the new firmware blob.
Updates are then triggered also via a simple write to a sysfs
file (nvm_authenticate), which in turn is also used for error
reporting.
The plugin should be functionally, but a few items are missing:
- image verification
- safe mode handling
