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.
This support was using the wrong commands to add a HWID and thus
never actually functioned. Furthermore it's purpose is to pull
the PID out of the bootloader to be able to properly identify
the device when in bootloader mode (as in recovery mode).
When in this state, generate the correct instance IDs for both
possible Wacom VID. We can't tell which Wacom VID we are in
bootloader mode.
This makes everything simpler, at the expense of not being able to create a
`BootFFFF` entry -- but if we get that far something has already gone very
wrong with the firmware...
Some derivative distributions re-use bootloader paths from their
upstream. When this happens the current logic to look for the `ID`
key in `/etc/os-release` doesn't work properly.
Adjust the logic to:
1) Use `ID`
2) Test the path exists. If so, use it.
3) If it doesn't use `ID_LIKE`.
4) Test if that path exists, if so use it.
5) If that path doesn't exist, return the key from `ID`
6) The plugin will make this path.
This fixes a regression introduced by 2031ce3bf6
that leads to:
```
USB error on device 2dc8:5750 : No such device (it may have been disconnected) [-4]

The GNU gold linker uses the section name `.rela.dyn` instead of
`.rela` for containing the relocation information. If this section
is not copied the EFI executable can crash.

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.

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

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:

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:

however, make the device it creates replace the dummy device:

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.

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.

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
I'm getting a bit fed up with failed reports from arch users where they just
have a broken system. I don't think it's useful to upload to the LVFS or notify
the vendor about failures like this.
The timeout to wait for the modem after being uninhibited was until
now exclusively to cover the port probing time, because the device
would be already available and ready to be used as soon as the
inhibition was removed.
With the change to include carrier config selection as part of the
fwupd upgrade process, the time to wait for the modem after being
uninhibited should now cover a full reboot of the module, and so the
original timeout of 45s could be a bit tight under some circumstances
(e.g the MM device probing logic is quite slow when there is no SIM
card detected by the module).
We increase this timeout to a much safer value of 120s, which is
extremely long for most cases, but should also be enough to cover even
the worst case scenario.
When we install the MCFG carrier config files with QMI PDC, we were
not explicitly selecting one, and that would end up reporting the
"DF" (default) config is in use. Instead, we should explicitly select
the carrier configuration that we were using before the firmware
upgrade operation.
For example, if the device originally was running with the Vodafone
specific carrier configuration (e.g. T77W968.F1.0.0.3.7.VF.009) and we
trigger the upgrade to the next available firmware associated to
the Vodafone carrier (e.g. T77W968.F1.0.0.3.8.VF.009), we would want
the device to boot with the Vodafone carrier config selected, instead
of booting without any config selected (T77W968.F1.0.0.3.8.DF.009).
This also fixes several upgrade problems detected by fwupd, because it
may end up complaining that the target firmware that was selected to
be installed (e.g. VF variant) is not the one actually reported by the
device after the upgrade (e.g. DF variant).
The selection of which is the config to activate is based on mapping
the mcfg file name with the firmware version reported by the module
before the upgrade. E.g. if the VF variant is reported by the module
(T77W968.F1.0.0.3.7.VF.009), fwupd will look for a MCFG file named
with the "mcfg.VF." prefix.
fu_uefi_get_esp_path_for_os() generates the path to the OS directory
based on "ID" in /etc/os-release, and it may not work for some distros.
Take openSUSE as an example, the "ID" for openSUSE Leap is
"opensuse-leap" and that for openSUSE Tumbleweed is "opensuse-tumbleweed".
However, both of them use the same OS directory in the ESP, i.e.
"/EFI/opensuse".
This commit adds a new build option, efi_os_dir, to allow the packager to
specify the name of OS directory at build time instead of the runtime
detection.

I'm not sure why we can't just use SIO_LDNxx_IDX_CHIPID1, but lets do the same
as the vendor tool in case there is a good reason that I don't know about.
Some system firmware helpfully 'deduplicate' the boot loader entries based on
the filepath, without taking into account either the label or optional data.
This means we have to use a custom copy of shim for firmware updates.
This was caught by LGTM.
This pointer might have type struct <unnamed> (size 28), but the
pointer arithmetic here is done with type UX_CAPSULE_HEADER * (size 16).
This feature is turned on with the new fwupdtool option `--enable-json-state`
The intended use case is for ChromeOS to be able to save information about
devices on the system when `fwupdtool update` was run to display in the UX at
a later time.
If a device reports that qmi-pdc is supported (e.g. DW5821e that
supports both fastboot and qmi-pdc), we'll end up first running the
fastboot installation before doing the qmi-pdc installation procedure.
These changes also make sure that the MM device inhibition is kept for
as long as the whole process is ongoing. Only after the last method is
run, the inhibition will be removed.
In order to handle devices being exposed in the system while the MM
inhibition is in place, e.g. to be able to run qmi-pdc after fastboot,
a simple udev based watcher is included, which will take care of
creating the FuMmDevice that is not associated to any modem currently
exposed by MM, but that shares all the details of the original device.
This new logic assumes that the devices don't change their USB layout
during a firmware upgrade, which is not a very good assumption, but it
works for the case at hand. If this is not the case, we may need to
end up doing some custom AT port probing instead of relying on the
original one reported by MM being still valid (note that we don't rely
on the device name, as that may change if some other device is plugged
in the system while we're doing the update, we rely on the USB
interface number).
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 is intended for devices that it is not safe to immediately activate
the firmware. It may be called at a more convenient time instead.
Both fwupdmgr and fwupdtool support the feature.
- if called at runtime with fwupdmgr it uses the daemon
- during shutdown fwupdtool uses the pending.db to perform this feature.
In some situations SELinux prevents fwupd from executing tpm2_pcrlist, but the
failure mode is that the process just hangs and never completes. This causes
systemd to time out the fwupd daemon startup and then errors to be shown in
GNOME Software.
To prevent this happening, add an optional timeout argument to
fu_common_spawn_sync() and cancel the subprocess if it takes longer than this
to complete.
See https://bugzilla.redhat.com/show_bug.cgi?id=1665701 for details.
The order of events when casting causes an access to unintended memory.

EC23 is the last version that will be supported on board 4 SKUs with
base PD firmware versions 18+.
* If on EC23 already, don't mark the device as updatable anymore.
* Flashing EC24 or later when currently on EC 22 or less will potentially
cause bricked docks that can't enumerate, so prevent this scenario
during update path.
The unifying version numbers are of the form 'RQR24.00_B0000' which means we
have to force the plugin to 'plain' version format to avoid stripping out the
non-semver chars.
Fixes https://github.com/hughsie/fwupd/issues/1018
The udev plugin is somewhat special as it uses a non-subclassed FuDevice that
never gets 'opened'.
This means that we never automatically call fu_device_setup() and thus the
instance IDs are not converted into GUIDs before the device is added.
The checksum is now stored as the very last flash descriptor, so we need to pad
the SREC data to include the 'missing' data range. As we're doing that, we
should optimize like the Wacom updater does and skip writing descriptors that
are unused.
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.
A device that has gone through a fastboot update may need more than
the previous default of 10s to come back up. Just use a much longer
value to make sure it's detected properly.

Splitting the file into lines does increase memory usage, but allows us to use
a much simpler parser design. This is just like we fixed IHEX a few weeks ago.
Some hardware from Lenovo deduplicates UEFI Boot entries, and uses the old
string 'Linux-Firmware-Updater' to avoid removing the firmware update entry.
Although this is forbidden in the UEFI specification we shouldn't break
firmware updates from old firmware versions.
Provide a quirk for this, and automatically whitelist anything with the LENOVO
SMBIOS Manufacturer.
This behavior will prevent the dock from performing most resets until
it has been unplugged from a host system.
This significantly speeds up the perceived update duaration and prevents
data loss during update.
It's not confirmed whether EC23 or later EC will enable it.
* So only enable by a custom flag until this is confirmed.
* Custom flag will be dropped when included into stable EC release.
This functionality also relies upon the CAB file providing a message warning
user that the dock might not be usable after unplugging for up to 1 minute.
Currently used structures were based on early libnitrokey definitions
(which were broken for some time). Corrected their sizes and elements,
and added tests.

Some aspects of the method for querying dock firmware do work in 'dell' plugin
but that is not useful for fwupd because it's incomplete.
Due to this the following error shows up in fwupd journal if run on a Dell system
when the new Dell dock is plugged in:
failed to add USB device 0bda:8153: failed to add device using on dell: invalid dock component request Query 3 0 2 4 0
Detect this scenario, and prevent showing errors in logs.
Unfortunately the previous fix (6131f5d) introduced this bug.
The code previously was actually looking for the non-zero case
which was correct, but non-obvious since `efi_guid_cmp` works like
`g_strcmp0` where a match returns zero.
So rather than revert 6131f5d make this completly explicit.
Affected drives should have a prominent statement in the update description,
possibly even the first line so it shows up by default in the updates panel.
Microsoft description about the Status is:
The Status field of the BGRT describes whether the image is currently
displayed on the screen. This is not applicable to the firmware update
display capsule.
Many thanks to Steven Chang for identifying this issue.

Some SKUs of board 4 and later have silicon that will not work with anything
but EC19 or later. So once flashed up to EC19 prohibit downgrades below that
to keep from bricking devices.
This is probably fall out from a previous code re-shuffling.
The EC version is already set elsewhere, and in many cases `self->ec_version`
is `NULL` at this time.
Board 4 was manufactured with package version 89.16.01.00 and this
will prevent properly upgrading between releases. Reset this version
to 00.00.00.00 if detected on this board.
We can't actually access the UEFI ROM from userspace, but the PCR0 is a hash
built from the ROM itself. We could use this value to ensure the firmware has
been written correctly, and that the PCR0 matches the expected value specified
in the metadata.
Future metadata from the LVFS will set the protocol the firmware is expected to
use. As vendors love to re-use common terms like DFU for incompatible protocols,
namespace them with the controlling company ID with an approximate reverse DNS
namespace.
This also allows more than one plugin to define support for the same protocol,
for instance rts54hid+rts54hub and synapticsmst+dell-dock.
This solves issues with implementations that require 4k alignment
of pages in BIOS which is seen on certain architectures.
The UEFI spec prescribes that the "minimum" size is the size of
the EFI header but that this may be increased up to larger sizes
due to extended header entries.
This mirrors the update process over DP aux to run the ESM update
first.
The thought process is as follows:
The "version" displayed doesn't show ESM version, only standard
bank version.
So if the update fails for the ESM then because the update of the
standard happening first it would never be flashed.
`g_ascii_strtoull` returns 0 and sets `errno` to `-EINVAL` only when
the base is invalid. It's hardcoded to `16` so this is impossible.
Reading `-EINVAL` from `errno` is incorrect in these circumstances.
Fixes: https://github.com/hughsie/fwupd/issues/879
This makes startup quicker as we no longer have to probe every USB device, and
is now possible with the new GUIDs we added. Devices not using the
specification-provided values can (and already are) worked around with quirks.
Otherwise this would cause fwupd to sit in an endless loop when providing a bad
image.
This additional enum is only available in EC16, but since it doesn't break existing
API on older EC images, don't bump minimum requirement to EC16 yet.
This metadata key is now unnecessary, as firmwares are expected to set the
version format in the metadata.
If the metadata is missing, the LVFS allows a per-vendor default for non-semver
release versions which is now unconditionally set in metadata.
Plugins are allowed to 'opt-out' of this behaviour using _RULE_INHIBITS_IDLE.
This should be used where waking up the hardware to coldplug is expensive,
either from a power consumption point of view, or if other artifacts are going
to be seem -- for instance if the screen flickers when probing display devices.
This functionality is also inhibited when the actual upgrade is happening,
for obvious reasons.
Admins can turn off this auto-sleep behaviour by editing the daemon.conf file.
Fixes https://github.com/hughsie/fwupd/issues/417
We load the Thunderbolt controller firmware to see if the controller is in
native mode, as this changes the GUID. If the controller is asleep the firmware
is not cached by the kernel and it can take more than 4 seconds to read out
504kB of firmware.
We only need the first two 64-byte chunks, so only read what is required.
This speeds up fwupd starting substantially, and also means we don't have to
allocate a giant chunk of heap memory just to inspect one byte.
Fixes: https://github.com/hughsie/fwupd/issues/848
The ids clash with the Xbox controller ids. This makes the Xbox controller unusable since fwupd unloads the device just after connecting it and fails to update it not being a 8bitdo device.
As seen here: https://github.com/paroj/xpad/issues/114
Since dell_dock is the priority plugin for MST flashing the VMM5331
no need to do delayed callbacks anymore.
When the dell_dock plugin bumps to EC 15 being the minimum requirement
more code can also be dropped.
1. Since board ID in synapticsmst.quirk is different based upon how
the board ID is read, don't whitelist it in `write_firmware`
2. Allow using `--force` with `fwupdmgr` or `fwupdtool` to override
board ID check.
3. Allow using custom flag `ignore-board-id` to ignore board IDs.
This will be the default for EVB boards and can be used in the event
of a factory mistake as well.
4. Move the EVB board IDs into their own synapticsmst_evb.quirk.
This file will not be installed by default (So EVB boards are only
functional when manually installed).
Although this is (currently) slower to flash with, bad behavior
and corner case scenarios such as these don't occur:
* Flickering during enumeration
* Monitor plugged in during enumeration but not during flash
* Heavy DP traffic slowing down update significantly
* Sandboxes without access to `/dev/drm_dp_auxY` unable to flash
* Exercising existing graphics driver bugs leading to system freezes.
Additionally this removes a lot of code in dell_dock that was put
in place specifically to be able to support waking up the MST hub
to try to use DP aux for flashing.
Now DP aux will only be used to flash when fwupd is compiled
without `dell_dock`.
It was identified that at least one other device on this shared
I2C bus can't operate at the speed. This means that it may
inadvertently respond to commands intended for another device.
Ensure the quirk object is set, and then add the GUIDs first so that the
version format can be set from a quirk file.
Additionally, only overwrite the fallback name if the name has not already been
set manually from a quirk.
The libxmlb library is much faster to query, and does not require the daemon
to parse the XML metadata at startup. It's a zero-copy mmap design that is more
modern and less clunky.
RSS has reduced from 3Mb (peak 3.61Mb) to 1Mb (peak 1.07Mb) and the startup
time has gone from 280ms to 250ms.
These are certainly bugs with one of the components, but if the situation
happens in the field the plugin needs to finish initialization to allow
upgrading to a fixed component.
We'll just fall back to the name in the quirk (Dell dock) in this case.
This plugin requires infrastructure introduced in fwupd 1.1.3
and can not be backported to earlier versions of fwupd.
It works together with the Synaptics and Thunderbolt plugins to
coordinate the proper flashing procedure for devices in this dock.
This allows a frontend to call update on an individual device ID which will
cause a CAB file to be downloaded, but then also re-use the same CAB file to
try to process devices with a relationship as part of a transaction.
The linker does not know which public symbol to call if a plugin calls it's own
symbol. Without this change one plugin could call into another plugin with the
wrong GsPluginData set -- which will probably explode in a ball of flames.
The profiling data is of limited use, and better data can be obtained using
kcachegrind and massif. Additionally, the profile samples were the cause of the
small RSS growth over time, when in reality the data would only be shown when
the verbose switch is used at daemon startup.
Since it matches the Realtek dongle, shouldn't show this error:
failed to add USB device 0bda:8153: no dock detected
All the time when that dongle is plugged in
It seems the 'Notebook' vendor is padded with spaces in the DMI data, and so
the GUID changes now we're following the same stripping scheme of Windows 10.
Now devices can have multiple GUIDs and do not share platform IDs there is
really no point waiting to add the device.
This allows us to remove a whole lot of code for this now-unused functionality.
This started popping up in Arch CI:
../fwupd/plugins/uefi/fu-uefi-vars.c: In function ‘fu_uefi_vars_get_data’:
../fwupd/plugins/uefi/fu-uefi-vars.c:233:9: error: pointer targets in assignment from ‘gchar *’ {aka ‘char *’} to ‘guint8 *’ {aka ‘unsigned char *’} differ in signedness [-Werror=pointer-sign]
*data = g_steal_pointer (&data_tmp);
^
Until now, the unifying plugin was a 'special snowflake' and did things in very
different ways to the other plugins. Refactor each object to derive from either
FuUsbDevice or FuUdevDevice, and then remove LuDevice and the LuContext layers.
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).
As an example use case earlier development versions of a Thunderbolt module
may contain DROM corresponding to one model ID and transition to another
model ID. Even if lying about the GUIDs supported by the device via a
quirk the Thunderbolt validation will fail because the device isn't
intended for that system.
This should only be used during development.
The daemon creates a baseclass of either FuUsbDevice or FuUdevDevice when the
devices are added or coldplugged to match the quirk database and to find out
what plugin to run.
This is proxied to plugins, but they are given the GUsbDevice or GUdevDevice and
the FuDevice is just thrown away. Most plugins either use a FuUsbDevice or
superclassed version like FuNvmeDevice and so we re-create the FuDevice, re-probe
the hardware, re-query the quirk database and then return this to the daemon.
In some cases, plugins actually probe the hardware three times (!) by creating
a FuUsbDevice to get the quirks, so that the plugin knows what kind of
superclass to create, which then itself probes the hardware again.
Passing the temporary FuDevice to the plugins means that the simplest ones can
just fu_plugin_device_add() the passed in object, or create a superclass and
incorporate the actual GUsbDevice and all the GUIDs.
This breaks internal plugin API but speeds up startup substantially and deletes
a lot of code.
If another plugin causes a Synaptics MST device to be removed, it
also needs to be removed from the cache to prevent problems when
the device is re-probed.
1) Switch to daemon provided vfuncs for USB
2) Set quirks so that the plugin only runs when Realtek NIC shows up
3) Rely on the daemon to process all removals by parent tree
The setup() is the counterpart to probe(), the difference being the former needs
the device open and the latter does not.
This allows objects that derive from FuDevice, and use FuDeviceLocker to use
open() and close() without worrying about the performance implications of
probing the hardware, i.e. open() now simply opens a file or device.
These are GUIDs that are related to the main device, but should not be used for
quirk matching. For instance, we might want to list the GUIDs for a bootloader
mode, but we don't want to import all the quirks for the bootloader when in the
runtime mode.
This flag is intended for devices that the restart procedure will
be performed as part of a transactional update by an external
controller.
None of the currently supported devices need this flag.
This allows us to match non-DeviceID GUIDs, and also GUIDs we don't know how to
generate.
To make this fully useful, search for device quirks when GUIDs are added.
This was compiling and passing CI as the un-implemented legacy functionality
was still exported in the header.
Remove the prototypes for the missing symbols and fix up the plugin.
Apparently the linker complains when dlopen'ing a plugin that's linked against
the libfwupdprivate library the daemon is using. This only seems to happen when
using distro packages...
The size check would always short circuit as
FU_WAC_DEVICE_FEATURE_FLAG_ALLOW_TRUNC == 0
is never true. The error message was thus never
written even if a difference was found.
With this patch we check if ALLOW_TRUNC is set in flags
instead, and only write the error if it is not.
Five plugins (soon to be 7) are linking to the DFU plugin just for this simple
segment-aware chunking functionality. Move this into common code to make
building simpler.
systemd-automount will unmount the ESP when not in use for some
people. This causes automatic ESP detection to fail.
In this case the ESP will need to be added to the conf file and
then this commit will let it keep working.
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.

Since the multi controller entry is part of the DROM and its place is
not fixed, it is possible (however unlikely) that the locations between
controller and the image are different. One scenario is that the new
image has typo in device or vendor name string fixed which could cause
the offset to be different.
To handle this case properly we need to read multi controller locations
of both controller and image separately, read their values and then
compare them against each other.

During review it was pointed out that the return value of
