This prevents horrible things happening when different plugins provide the
parent and child, and the child gets added before the parent.

In this instance, we define the 'same device' to be a FuDevice that has at
least one matching GUID. We allow the plugins to define which one is 'better'
than other plugins, and use this to only have one FuDevice for the physical
device.

This pivots the data storage so that the group is used as the preconditon
and the key name is used as the parameter to change. This allows a more natural
data flow, where a new device needs one new group and a few few keys, rather
than multiple groups, each with one key.
This also allows us to remove the key globbing when matching the version format
which is often a source of confusion.
Whilst changing all the quirk files, change the key prefixes to be more familiar
to Windows users (e.g. Hwid -> Smbios, and FuUsbDevice -> DeviceInstanceId)
who have to use the same IDs in Windows Update.
This also allows us to pre-match the desired plugin, rather than calling the
probe() function on each plugin.
Now we can update multiple devices (in multiple plugins) using one firmware
archive we need a way to cleanup after all the plugins have been run.
Fixes https://github.com/hughsie/fwupd/issues/561
Fixes a segfault that occurs during cleanup of USB plugins.
When g_module_close was called memory allocated by the plugin would
get freed leading to the finalize method for object class pointing
to garbage.
This allows us to find out the logical parent device, for instance in composite
devices with more than one firmware image for a single device.
We also allow lazily specifying the device parent using a GUID and the engine
then automatically sets the parent object when the GUIDs match, which allows
children and parents to exist in different plugins.
This allows plugins to set and explicit build-time version. It also uses the
same AppStream component-ID scheme rather than the home-grown 'FooVersion' key.
Also, use the new runtime and compile-time versions in the report metadata.
Due to the key change we'll also need to update some LVFS rules.
In some cases firmware can only be installed with an up to date GUsb (e.g. with
some STM-DFU hardware) or with a new version of fwupdate (e.g. any UEFI
UpdateCapsule without a capsule header).
We should be able to match against other software versions like we can the
fwupd version, e.g.
<requires>
<id compare="ge" version="0.9.2">org.freedesktop.fwupd</id>
<id compare="ge" version="11">com.redhat.fwupdate</id>
</requires>
Also, rather than checking each requirement we know about on the component,
check each requirement on the component about things we know. This ensures we
don't allow firmware to be installs that requires for instance fwupdate 22 when
the runtime version is only being added in fwupdate 12 and up.
This means the following is now an error that will fail to allow the firmware
to be installed:
<requires>
<firmware>doesnotexist</firmware>
<some_future_tag>also_unknown</some_future_tag>
</requires>
Also add a lot of self tests to test the various new failure modes.
Fixes https://github.com/hughsie/fwupd/issues/463
If this happens:
1.2.3 -> 1.2.4 = failure
1.2.3 -> 1.2.5 = success
...we want to preserve both in the history database so they can both be shared
with the LVFS. Use the device ID and the new and old firmware versions when
modifying and deleting entries.
This fix is made slightly more tricky as we have to drop the PRIMARY KEY
attribute on the device_id, and due to a limitation in SQLite, it means copying
the old history into a new table.
Previous to having the history database we could only notify about firmware that
as installed using the uefi plugin, as that had a few system-wide API calls to
say 'this update failed' or 'this was the error'.
Now we have the local history database not only can we report more details about
the UEFI update (e.g. the old version number) but we can also offer the same
functionality for all other plugins.
Although this does rework how the data for GetResults() is populated, it does
make the FuEngine object quite a lot less confused.
It also fixes a warning in the fwupd plugin for gnome-software, which was
expecting the FwupdRelease to be populated for the FwupdDevice.
Rename FuPending to FuHistory to better represent what the object is now doing.
Also, while we're here, switch to using SQLite prepared statements to avoid a
possible invalid read on i386 hardware.
The name, summary and icon are not strictly required for a USB device
supporting both DFU interfaces, but having this extra data makes GNOME Software
look much nicer. Using the quirks feature means we can merge in support for new
devices after fwupd has been released for stable distros.
This saves all the USB plugins from connecting to the context and managing the
device lifecycle and allows devices that uses FuUsbDevice to be removed
automatically.
This makes supported plugins *much* smaller indeed.
This allows us to do two things:
* Attach after a failed update, so the user isn't left with 'dead' hardware
* Split the detach and attach actions into different plugins in the future
This also allows us to have a separate vfunc to get the new version number
after flashing the firmware, as this may be handled in a different plugin to
the detach phase.
When fwupd is installed in long-term support distros it's very hard to backport
new versions as new hardware is released.
There are several reasons why we can't just include the mapping and quirk
information in the AppStream metadata:
* The extra data is hugely specific to the installed fwupd plugin versions
* The device-id is per-device, and the mapping is usually per-plugin
* Often the information is needed before the FuDevice is created
* There are security implications in allowing plugins to handle new devices
The idea with quirks is that the end user can drop an additional (or replace
an existing) file in a .d director with a simple format and the hardware will
magically start working. This assumes no new quirks are required, as this would
obviously need code changes, but allows us to get most existing devices working
in an easy way without the user compiling anything.
This allows us to fix issues like https://github.com/hughsie/fwupd/issues/265
This allows a plugin to see if a GUID is supported in the AppStream metadata of
configured remotes. It allows plugins to skip devices that are not supported
and that do bad things when probed.
By removing the device from the hash table before we add it to the devices
array we could inadvertently drop the last object reference if the plugin is
not using the (optional) cache.
Just re-arrange things to fix https://github.com/hughsie/fwupd/issues/259
It only remained on FwupdResult because I couldn't make up my mind about whether
it was a property of the device, or the firmware release. It's more logically
the former, and that's how plugins are using it.
The Linux DMI class still does not provide the information we need, and parsing
the blob directly also allows the Dell and Redfish plugins to get the raw data.
Over the months the original meaning of ALLOW_OFFLINE and ALLOW_ONLINE have be
lost, and there is now a confusing mixture of uses in the source tree. With this
commit we make it clear the UPDATABLE flag is used to specify when the device is
updatable (e.g. from the desktop live session, or from the systemd offline
updates mode, or both) and the NEEDS_REBOOT flag lets us know when the update
is actually going to be done.
For instance, a UEFI UpdateCapsule can be *scheduled* from either the desktop
or from the update mode (but the latter would be a bit weird), but does require
a reboot. Some devices might only be updatable outside the live session, for
instance a hard drive update or a GPU update -- there's just too much going on
with a live session and we want to tightly control what's running during the
firmware flash.
This also means we don't have to "retry" the update when scheduling an update
that really can be scheduled whenever, but just requires a reboot to apply.
This could be used, for instance, to set a property on ThunderBolt controllers
inside Dell computers saying that they support forcing the power level during
coldplug. It could also be used to set the dock type for the synapticsmst hub.
Adding this level of complexity allows us to avoid the creep of HAVE_DELL and
HAVE_LENOVO into seemingly unrelated plugins, and also allows us to have
multiple vendor plugins providing the same end result with two different
vendor-specific mechanisms.
Although we supported other hashes than SHA1 (which is now moderately unsafe)
we had to switch the metadata provider and daemon on some kind of flag day to
using SHA256. Since that's somewhat impractical, just allow multiple checksums
to be set on objects and just try to match whatever is given in preference
order.
This also means we can easily transition to other hash types in the future.
The removed API was never present in a tarball release, so not an API break.
This commit provides a new "hwids" subcommand for fwupdmgr that shows the
hardware GUIDs on the local system. It also provides API that plugins can use
to self-disable when a specific HWID does not match.
The GUIDs used in this implementation match that of ComputerHardwareIds.exe
Packagers should still enable it so that tracking lost memory
in plugins is possible, but on some distros some archs don't
have valgrind available which would otherwise prevent fwupd
from running.
This is as problem currently for Debian unstable where some
archs valgrind fails to compile.
Poll each plugin, and only register the service when all the delayed coldplug
devices have been added to the device list. This prevents returning an error
when calling "fwupdmgr get-devices" for the very first time.
Resolves: https://github.com/hughsie/fwupd/issues/82
This allows a plugin to signal the daemon that something has happened and that
all plugins should wake up connected devices, re-add them all and then put the
devices back to powersave mode. Any duplicate devices will be ignored.
This is a large commit that removes all the providers and turns them into
plugins. I think having both providers _and_ plugins was super confusing.
Plugins are loaded at runtime so you could in theory develop a new plugin
without putting it in the fwupd source tree, although there are no installed
headers or PC files as I'm not sure it's a good idea at this stage.
This commit moves all the per-provider docs, tests, notes, debug dumps and test
data to plugin-specific directories -- these also allows the plugin author to
"own" more of the source tree so we don't enforce fu- prefixes and the style
guide everywhere.
This allows us to run the same action on all the plugins in the future, so we
could have a prepare(FuPlugin, FuDevice) and cleanup(FuPlugin, FuDevice) run
on *all* plugins, so doing an update using one plugin would allow us to work
around hardware quirks in other plugins.
If I've broken your out-of-tree provider it's trivial to port to the new API
with sed and a fixed up build file. If you need help please let me know.
This means we don't have more that one thread just watching for the USB
hotplug events. To achieve this split up the coldplug into setup and coldplug
phases and run the enumerate just once in the daemon.
