The activation flag is stored into the history database, but not all
plugins will want to inherit it on coldplug the next time the daemon
is started.
For example the Dell Dock plugin will query this information from the
device and it will prevent getting into a bad state as a result.
Fixes: #3106
This allows us to 'nest' firmware formats, and removes a ton of duplication.
The aim here is to deprecate FuFirmwareImage -- it's almost always acting
as a 'child' FuFirmware instance, and even copies most of the vfuncs to allow
custom types. If I'm struggling to work out what should be a FuFirmware and
what should be a FuFirmwareImage then a plugin author has no hope.
For simple payloads we were adding bytes into an image and then the image into
a firmware. This gets really messy when most plugins are treating the FuFirmware
*as* the binary firmware file.
The GBytes saved in the FuFirmware would be considered the payload with the
aim of not using FuFirmwareImage in the single-image case.
Devices may want to support more than one protocol, and for some devices
(e.g. Unifying peripherals stuck in bootloader mode) you might not even be able
to query for the correct protocol anyway.
This allows a device subclass to call the parent method after doing an initial
action, or even deliberately not call the *generic* parent method at all.
It also simplifies the plugins; you no longer have to remember what the plugin
is deriving from and accidentally clobber the wrong superclass method.
At the moment FuChunks are sometimes mutable, and sometimes immutable, and it's
all a bit too low level for comfort.
Before we can do any kind of optimisation or verification we need plugins to
stop reading directly from the C structure. The aim here is to make FuChunk
optionally mutable without making assumptions about the memory model, and also
to be able to introspect it for the docs.
That giant uint64_t isn't looking so big now, and we'll want to add even more
to it in the future. Split out some private flags that are never useful to the
client, although the #defines will have to remain until we break API again.
Asking the user for the UID mapping isn't working very well, as it requires lots
of manual handholding. It also doesn't work very well when the device vendor
does not actually have a PCI ID or if the vendor has split into two entities.
Just use the OUI address as an additional VendorID and match any of the device
IDs against any of the metadata-supplied values.
Sometimes we only want to add the instance ID to get the quirk matches, and it
is confusing to see the "fake" IDs in the 'fwupdmgr get-devices' output.
If we say that the version format should be the same for the `version_lowest`
and the `version_bootloader` then it does not always make sense to set it at
the same time.
Moving the `version_format` to a standalone first-class property also means it
can be typically be set in the custom device `_init()` function, which means we
don't need to worry about *changing* ther version format as set by the USB and
UDev superclass helpers.
Some vendors want to ship updates for ATA hardware, but there are currently no
lock-down restrictions in place for these kind of devices.
There is the OUI from the WWN block which is supposed to identify the vendor,
but this is not always set and so we have to be a little creative. We can match
90% of hardware using the vendor name prefix, and the last 10% can be detected
with a heuristic that was the result of comparing over 900 drive models.
I'm not including very old drive models, media converters, raid controllers,
or external 'portable' drives as I don't think it is useful. Also, if the drive
contains a Dell vendor block just hardcode this as Dell rather than trying to
be clever.
Also ask the user to contribute OUI values if this data is found with no quirk
data as this is the only real sane way to manage this data long term.
The list of OUIs can be found here: http://standards-oui.ieee.org/oui.txt
Some plugins have devices with more than one protocol. Logically the protocol
belongs to the device, not the plugin, and in the future we could use this to
further check firmware that's about to be deployed.
This is also not exported into libfwupd (yet?) as it's remains a debug-feature
only -- protocols are not actually required for devices to be added.
In many plugins we've wanted to use ->prepare_firmware() to parse the firmware
ahead of ->detach() and ->write_firmware() but this has the limitation that it
can only return a single blob of data.
For many devices, multiple binary blobs are required from one parsed image,
for instance providing signatures, config and data blobs that have to be pushed
to the device in different way.
This also means we parse the firmware *before* we ask the user to detach.
Break the internal FuDevice API to support these firmware types as they become
more popular.
This also allows us to move the Intel HEX and SREC parsing out of the dfu plugin
as they are used by a few plugins now, and resolving symbols between plugins
isn't exactly awesome.
This leads to madness, as some formats are supersets of the detected types,
e.g. 'intel-me' is detected as 'quad' and 'bcd' is detected as 'pair'.
Where the version format is defined in a specification or hardcoded in the
source use a hardcoded enum value, otherwise use a quirk override.
Additionally, warn if the version does not match the defined version format
This will allow us to switch to the new firmware version during shutdown when
the filesystems have been remounted readonly.
Activating manually means we don't have to get the user to shutdown and then
do a fresh power-on, rather than the more usual restart.
This also allows us to write mixed-endian structures and adds tests. As part of
this commit we've also changed the API of something that's not yet been in any
tarball release, so no pitchforks please.
This allows hardware from OEMs to *not* match generic firmware supplied by the
device manufacturer. The idea being, that the OEM will supply firmware that
will actually work on the device.
Based on a patch from Mario Limonciello, many thanks.
Similar to NVME, ATA drives distributed by Dell have special values
that should be used to designate fwupd GUIDs and only run correct
firmware.
When detecting Dell GUIDs remove the standard fwupd GUIDs. "Generic"
firmware targeted to those GUIDs will fail to install.
During download and activation we have to reset the drive to apply the new
firmware. If the kernel gets an unexpected ATA reset then it might panic.
Default to activating the command on the next drive power-up to be safe.
Many thanks to the Dell storage team for the advice.
