fu-udev-device will open a locker automatically now.
However synaptics-rmi closes the file descriptor on it's own with `g_clear_object`.
So destroy the fd in synaptics-rmi.
Set `IS_BOOTLOADER` unconditionally when in fastboot mode. This seems logically
what it is; a degraded mode that's able to update firmware without runtime
functionality.
Fixes https://github.com/fwupd/fwupd/issues/1532
This allows us to do three things:
* Fuzz the loader with `fwupdtool firmware-parse`
* Check the firmware *before* the hardware is put into bootloader mode
* Use FuChunk to build the 32 byte payload chunks
Systems with multiple host controllers will most likely have a different
NVM image for each controller but there is no guarantee that the device_id
within the NVM image varies from one controller to another.
To account for this, build a GUID that contains the last element of the
Thunderbolt controller's udev path.
Sample GUID strings from an XPS 9380 (which only contains one host controller):
```
Guid: 0f401ed2-b847-532a-adc8-3193fc737be6 <- TBT-00d408af-native
Guid: 420b0596-f5cb-5fd7-8416-c99d48ad8de9 <- TBT-00d408af-native-0000:05:00.0
```
This commit follows the presumption that the kernel will enumerate the controllers
in the same order every time.
This also lets us remove the call to dfu_device_wait_for_replug() which was
causing a deadlock due to unsafe main context usage. Splitting the code allows
us to use the device list to watch for replug, without adding even more Jabra-
specific plugin code to the DFU plugin.
Looking at this with a 40,000ft view, the Jabra runtime really doesn't have
much in common with DFU and the reason it was originally all lumped together
was that the daemon couldn't "change" plugins between detach and update.
It's unfortunate that we have to include a sleep() in the DFU code after the
DFU probe, but this is specified by Jabra themselves. Attempting to open the
device without waiting reboots the hub back into runtime firmware mode, so we
can't even retry the failing setup action.
During startup we do 1898 persistent allocations to load the quirk files, which
equates to ~90kb of RSS. Use libxmlb to create a mmap'able store we can query
with XPath queries at runtime.
We can't use the IOTA mechanism in bootloader mode, and failing to create the
FuSynapromDevice object means we can't recover the hardware if the flash failed.
Some devices don't set the CAN_DOWNLOAD attribute in their runtime descriptor.
Rather than quirk these devices just assume that all DFU devices with a DFU
interface can download in DFU mode. The logic being, why would they expose a
runtime DFU interface if they can't download new firmware in DFU mode...
Devices like the DW1820A that are currently blacklisted because of broken DFU
support will remain blocked with this change.
This makes the daemon less destructive at startup, especially if the ESP
is not mounted.
It's stored in 3 different places right now, so move it into one point of truth.
Now the ESP is detected when needed including all point of time safety checks and
dynamically mounted and unmounted if necessary.
It appears to only happen on non-dell systems trying to look up system
ID through `sysinfo_get_dell_system_id`
Other than CI non-dell systems won't be running this code.
Detect and parse current coreboot version.
There's no need to depend on libflashrom for now.
An update mechanism isn't implemented as the kernel interface isn't
stable yet and will be implemented in a separate commit.
Tested on coreboot enabled machine.

Actually trying to instantiate the object leads to:

This was a new file format to help out an OEM, but they didn't actually use it.
If we do need it in the future, it would some back as a src/ helper, not in
plugins/dfu.
We don't support any hardware that actually uses this proposed standard, and
nowadays there is much better public-key encryption people can easily use.
Use this attribute to determine whether or not to try to read 'native'
from the Thunderbolt NVM image at probe time.
This attribute is new to kernel 5.5.
The new plugin is called `optionrom` as this is the only type of image that it
parses for verification only. FuUdevDevice is also the generic parent already.
Although they can be useful for debugging the codepath leading to
a problem, they are also confusing when it comes to the end user
messages:
```

{error #1} linux.c:406 device_get(): readlink of /sys/block/nvme0n1/device/driver failed: No such file or directory

```
Whereas if they weren't shown, that last message would have been plenty.
Avoid checking if bolt supports force-power in coldplug (early on)
because that will dbus-activate boltd, even on systems where there
is no actual thunderbolt hardware and thus also no force-power
support. Since boltd does use the very same kernel mechanism that
fwupd would use when boltd is not around this can not lead to any
regressions.
There are some packaging problems in some distributions that lead
to TSS stack emitting warnings that will fail self tests.
These don't occur as root, and furthermore those distributions run
CI as root already.
And in the dell plugin make it non-fatal to have TPM register read failures
in case the system has TPM1.2 not TPM2.0
If we're using an instance ID with FU_DEVICE_INSTANCE_FLAG_ONLY_QUIRKS (e.g.
for the vendor match in the previous commit) then the GUID is not available.
When the system doesn't support UEFI capsule updates no firmware version
is displayed for the BIOS. Fix this by creating a dummy device:
```

│ Current version: 1.7.0

│ Update Error: UEFI Capsule updates not available or enabled
│ Flags: internal|require-ac|registered|needs-reboot
```
If the dell-esrt plugin determines that capsule updates can be enabled
however, make the device it creates replace the dummy device:
```

Fixes: #1366
The factory-shipped MinnowBoardMAX board has firmware that does not include
the ESRT table. Create a 'fake' UEFI device with the lowest possible version
so that it can be updated to any version firmware.
All the HwId GUIDs are used for the fake UEFI device, and so should be used in
the firmware metadata for releases that should recover the system.
The fwupd UEFI plugin refuses to start if bit 3 of the "BIOS Characteristics
Extension Byte 2" (13h) is cleared. Bit 3 is UEFI Specification is supported.
Also, double-check that /sys/firmware/efi does not exist before disabling the
plugin as other machines may be affected too. The quirk then acts to supress
the console warning about the broken SMBIOS value.

The new firmware for receivers with the nordic chips is using the 0x04

There are commits to the Thunderbolt kernel driver that make sure
that the upgrade process goes smoothly. If these commits aren't
present then it will look like a fwupd problem, when it's actually
a kernel problem.
When this issue was reported it appeared that commit
e4be8c9b6a
was missing from the locally tested kernel, but it's impossible
to determine that from userspace.
Prevent running the thunderbolt plugin on older kernels than that
set in `$sysconfdir/fwupd/thunderbolt.conf`.
By default that is set to 4.13.0, but if a distribution vendor has
backported all the necessary support it can be decreased to a lower
version for distro packages.
This removes the 'two-layer' FuDevice and FuSyanpticsmstDevice model, where
a complicated plugin cache was used to add and remove devices to the daemon.
By making FuSynapticsmstDevice derive from FuDevice rather than GObject we can
also use a lot of the helper functionality like the other plugins, for instance
->prepare_firmware().
The `drm_dp_aux_dev` devices do not emit uevents on unplug/re-plug and so all
devices of `drm` class are watched and the actual DP AUX devices rescanned after
a small delay. When the AUX devices emit changes from the kernel this workaround
can be removed.
Also drop force power support for MST controllers in the Dell plugin. Overall
this has just led to more problems than it's helped.
* Monitor flickers when turned on
* Crashing graphics drivers from time to time
* Fragile logic that doesn't always represent the device state
The test is run if a physical TPM is available or if the environment
variable "TPM_SERVER_RUNNING" is set. In the latter case, the user is
expected to start a TPM simulator on their own, like we do in the Arch
Linux CI script here.
Using the library instead of the command line tools provides a more
stable interface. This implementation only fetches PCR 0 for all
available hash algorithms since this is the only PCR that is actually
used in fwupd.
tpm2_pcrlist has been renamed to tpm2_pcrread in
aedb0291d2
and the output format has changed slightly to include a leading "0x" in
9374bd70f4
Also add an example of the new output format to the self test.
This controller isn't flashable in fwupd, but fwupd can display information
about it.
* Use a generic device ID (similar to safemode)
* Build device name attribute from DMI data
This was previously used when the plugin was only run on Dell devices.
The plugin was already adjusted to run on other vendor's firmware
but this definition was not removed.
There are several subtle bugs in various places in fwupd caused by not treating
user-provided offsets into buffers as unsafe. As fwupd runs as root we have to
assume that all user firmware is evil, and also that devices cannot be trusted.
Make a helper to put all the logic into one place and convert all users.
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.
The DW5821e in modem mode uses the 0x81D7 PID, but when it boots in
fastboot mode it uses the 0x81D6 PID. The upgrade procedure was able
to automatically match these two devices because they both shared the
very generic per-VID (0x413C) GUID, but this is no longer operational
since commit 8ef139faba, as the very generic GUIDs have been removed
for matching purposes.
So, define a quirk for the DW5821e, in order to add a counterpart
GUID to make device matching work properly again.
Fixes https://github.com/hughsie/fwupd/issues/1271
If we add or remove a quirk from a machine using the uefi plugin then the new
setting is not used until the BootXXXX EFI key is manually removed. Rather than
just writing the contents of the found key back to the key (doh) just write the
new DP buffer contents if it is different from the previous buffer.
This allows the ODM to specify command line arguments such as:
--flags=use-shim-unique,use-legacy-bootmgr-desc,no-ux-capsule
..which is useful for testing broken firmware.
This difficult to debug bug only showed up when the fwupd service was stopped,
which the user never noticed, but services like abrt were still keen to report.
The root issue was that the call to fu_plugin_get_smbios_data() in
fu-plugin-uefi.c:fu_plugin_startup() was freeing the returned const GBytes,
which rippled down all the way to a double-free deep in libxmlb.
It's somewhat unusual to have a const GBytes, so just change the plugin helper
to returned a ref'd copy, on the logic a potential 16 byte memory leak is better
than a double-free when the next plugin gets the logic the wrong way around.
Fixes https://bugzilla.redhat.com/show_bug.cgi?id=1734746
* Set UpdateError to indicate how the device needs to be updated
* Set the device as needing reboot
* If admin password is set show the message to frontend via `UpdateError`
I'm not 100% sure calling flashrom_programmer_init('internal') unconditionally
on every platform is a very good idea. Only probe the hardware if there is a
whitelisted supported device.
Fixes https://github.com/hughsie/fwupd/issues/1239
Users are getting confused when they're being told that AC power is required
when they are already on AC power... but the battery is too low to perform the
update.
* In startup, check BIOS characteristics for UEFI supported instead of for /sys/firmware/uefi
* In coldplug check for /sys/firmware/uefi
* If /sys/firwmare/uefi missing, create a dummy device telling the user it is in legacy mode
This also means we now include a flashrom subproject as no distro currently has
a flashrom new enough to build the plugin.
