The GLib g_byte_array_set_size() function does not zero the contents if the
array size is larger, which leads to unpredictable output when using valgrind.
To do this without rebooting the device implement VliUsbhubPdDevice->reload()
like the other FuVliUsbhubDevice child devices.
Fixes half of https://github.com/fwupd/fwupd/issues/2376
For instance, we can tell the user that UEFI UpdateCapsule is disabled in the
system firmware, or that efivarfs is not mounted. This is much better than
creating "dummy" devices which are really just hacks around the problem because
no better API existed. THe dummy devices cause as many problems as they solve.
Plugins have to set FWUPD_PLUGIN_FLAG_USER_WARNING if a warning should be shown
to the user, and only one warning will be shown of each failure type.
It is expected that GUI clients like gnome-software and gnome-firmware would use
this API to notify the user the localized message for why firmware updates are
not being shown.
Fixes https://github.com/fwupd/fwupd/issues/2456
Add quirks for PID 5048 and 5049, which are cros-ec devices
that update via USB endpoint. Notable about these two are
they support rw_sig, for RW region signature verification.
Our update flow prior to this was:
1. On detach, reboot to RO.
2. From Old RO, Update RW.
3. Reboot to New RW
4. From New RW, Update RO.
5. Reboot to finish
This flow has a flaw, which is that the Old RO may be buggy (especially
during development, before it's actually locked down and actually Read-Only).
This change will do the following instead:
1. On detach, do not reboot to RO if RO is writeable, and we are in RW
2. From old RW, Update RO
3. Reboot to new RO
4. From New RO, update RW
5. Reboot to finish.
This has a speed advantage as well, as we save one reboot cycle (2 vs 3).
As a result of the previous change, where we send an immediate reset to
devices in order to transition back to rw, we will end up reenumerating
as RO briefly, although the destination we wanted to get to was RW.
In that case, basically skip the write firmware step, set another write
required and allow the RO firmware to complete rw_sig and jump to the rw
partition.
Previously, we sent a 'stay-in-ro' subcommand when we are in
fu_cros_ec_usb_device_reset_to_ro, which is called from the detach phase,
in other words, we are currently sitting in RW.
This is incorrect, since stay-in-ro only interrupts an RO's
rw_sig process if it is in progress.
Instead, 'stay-in-ro' must be issued when the device reenumerates in RO,
immediately before the writing sequence starts. On devices that implement
rw_sig, they will briefly enumerate as RO before self-issuing a jump to RW
on the signature check being valid. In order to stay in RO to perform a RW
partition update, we must interrupt it as soon as we see the RO version
enumerate.
- Use pci function 0 instead of 1 when flashing firmware.
In certain situations, the BCM5719 NVM controller can lockup if
a function other than 0 is used to read from NVM word-by-word like
the kernel driver does.
- Fix APE_MODE offset in BAR[2] to enable proper resetting of the APE.
- Remove unnededed NVRam lock when resetting the APE.

Based on a patch by Mario Limonciello <mario.limonciello@dell.com>, many thanks.
When support for dynamically mounting disks was added for 25ba41579f
udisks2 became a harder dependency and it was less obvious to users.
Create devices but show an error in why devices aren't updatable if
it's not found.
Users can still configure ESP manually in `uefi.conf`
Fixes: #2444
The FWUPD_INSTALL_FLAG_FORCE flag has really unclear semantics, and ignoring a
file CRC, checksum or model ID should only be done when using fwupdtool actually
debugging a plugin or firmware parser.
Use the existing --force flag when we want a "gentle nudge" like reuploading
previously processed reports.
This allows us to handle this in the plugin, which might mean detaching the
*proxy* device. It's also very important as a few plugins reboot the device
in ->attach() to get the new firmware version, which isn't required for a dump.
This partially reverts a58510b246 and does the
detach and attach in the few plugins where actually required.
With how well fwupd UEFI updates work these days >99% of people
don't need to see messages about the capsule update running.
Those who have problems, this isn't going to help them.
Firsly, that HSI isn't expected for embedded devices and then secondary how we
require SecureBoot to be available for HSI:1
At the moment we get a runtime failure if it is disabled. Making SB a part of
`HSI:1` makes this requiremnt explicit and prevents us getting `HSI:2!` if it
is not available.
The 721C is a VL103, which isn't a FuVliUsbhubDevice at all. Fixes the:
already set GType to FuVliPdDevice, ignoring FuVliUsbhubDevice
...message when the Mini dock / powered hub is inserted.
Use one of the errors mapping to FWUPD_UPDATE_STATE_FAILED_TRANSIENT to avoid
uploading a failure report for something the user has to fix, i.e. update the
distro shim package.
Conceptually we were trying to stuff subtly different actions into one vfunc:
* Read firmware from the device to update the verification checksums
* Read a firmware blob from the device for debugging
For the first action we might want to mask out the sections of the flash with
serial numbers (so the verification hashes match the ones published on the LVFS)
and for the second we want just a raw ROM file from the hardware with no
pre-processing that we can compare against an external SPI dumper.
Split out ->dump_firmware to get the raw blob, and allow plugins to also
implement ->read_firmware() if they have to mask out specific offsets or remove
specific images from the FuFirmware container.
In the common case when masking is not required, fall back to using a 'binary'
FuFirmware automatically to make most plugins simpler.
At the moment there are commands to convert one file format to another, but not
to 'merge' or alter them. Some firmware files are containers which can store
multiple images, each with optional id, idx and addresses.
This would allow us to, for instance, create a DfuSe file with two different
raw files that are flashed to different addresses on the SPI flash. It would
also allow us to create very small complicated container formats for fuzzing.
This can be used by writing a `firmware.builder.xml` file like:
<?xml version="1.0" encoding="UTF-8"?>
<firmware gtype="FuBcm57xxFirmware">
<version>1.2.3</version>
<image>
<version>4.5.6</version>
<id>header</id>
<idx>456</idx>
<addr>0x456</addr>
<filename>header.bin</filename>
</image>
<image>
<version>7.8.9</version>
<id>payload</id>
<idx>789</idx>
<addr>0x789</addr>
<data>aGVsbG8=</data>
</image>
</firmware>
...and then using something like:
# fwupdtool firmware-convert firmware.builder.xml firmware.dfu builder dfu
This is only applicable for kernel 5.9 or kernels that backported
the authenticate on disconnect patches.
For installation time this isn't very important since no device will
restart. This also isn't relevant for the authenticate on disconnect
scenario.
However the manual activation scenario, it's important to activate the
WD19TB device first, followed by Thunderbolt.
I2C doesn't have any specification for what is a probe and what is a more
destructive action. Sending tx_buf out on the i2c bus to a generic address
might not be safe in all cases.
To prevent this, use a HWID to check the machine DMI value during device
creation before ->probe() or ->setup() is called on the device.
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
This ensures we perform the updates in this order:
* cxaudio
* vli
* thunderbolt
As any other order causes enumeration failures.

This object derives from FuDevice rather than FuVliDevice and so does not
inherit the NO_GUID_MATCHING flag like other devices.

It seems the MEI parameters are not set for platforms such as Apollo Lake.
The only bit set was FPF_SOC_LOCK, with the others all cleared to zero.
Fixes https://github.com/fwupd/fwupd/issues/2335 for a peculiar definition of 'fix'.
As described in DFU protocol (7. Manifestation Phase), after the
firmware reprogramming is done, if bitWillDetach = 1, it doesn't
require the host to issue a USB bus reset, but the device can
generate a detach-attach sequence itself to go back to normal.
Add a quirk flag "no-bus-reset-attach" to skip the bus reset in
dfu_device_attach(), and increase the "RemoveDelay" as well.
Print the sysfs path for devices deriving from FuUdevDevice, which also allows
us to use FU_UDEV_DEVICE_DEBUG without monkey-patching the plugins that also
define a device_class->to_string() vfunc.
For some Poly USB Cameras, it takes a longer time than the
default (FU_DEVICE_REMOVE_DELAY_RE_ENUMERATE) for being detached
to DFU or attached to normal mode. Need to specify the timeout in
"RemoveDelay" quirk key.
Also replace the hard-coded timeout with fu_device_get_remove_delay()
in dfu-tool.c.
Some devices may accumulate the firmware image and perform the
entire reprogramming operation at one time. In this case, the
device enters dfuMANIFEST-SYNC or dfuMANIFEST state after
dfuDNLOAD-IDLE.
The fwupd shall be able to poll the status from the device via
DFU_GETSTATUS until the device completes the reprogramming or
reports an error.
For details, please refer to Section 7. Manifestation Phase and
A.1 Interface State Transition Diagram in the USB DFU protocol.
https://www.usb.org/sites/default/files/DFU_1.1.pdf
For not affecting the other DFU capable devices, introduce a quirk
"manifest-poll" to limit the logic.
The nr_chunks is defined as an unsigned short, the max value is
65536. Assume the transfer_size reported by device is 4096, the
maximum size of DFU firmware supported is 65536 * 4096 = 256MB.
To support larger DFU firmware, we can change the guint16 to
guint32.
This implements the following simple state machine:
1. Reboot to RO, Update RW first, set ANOTHER_WRITE_REQUIRED
2. Second time around, don't reboot into RO. Stay in RW.
3. Update RO.
4. Done.
Only add instance ID if it actually probes properly.
Otherwise this makes an invalid assumption that the device is a WD19
EC just because it had the correct hub in front.
Instead check the first time it's opened that the correct device
is identified (`EXPECTED_DOCK_TYPE`)
This is much more efficient than parsing hundreds of lines of /proc/cpuinfo
and also causes hundreds of thousands less allocations at startup. For systems
with dozens of virtual CPUs the deduplication of device objects was increasing
start up time considerably.
Use the msr plugin to read the microcode version as this is not obtained using
CPUID, as it is instead being provided in an MSR.
To do this mount all ESP partitions and check all the binaries there to see if
they match any entries in the new dbx. If we applied the update when a hash
matched, we would unintentially 'brick' the users machine, as the grub and shim
binaries *have* to be updated first.
This functionality does reimplement the PE hashing functionality found in
sbsigntools and pesign. This was done for 4 main reasons:
* There were some memory safety issues found when fuzzing random binaries
* Executing the tools hundreds of times was a lot of overhead
* Operating from a blob of immutable mmap'd memory is much faster
* We only need a very small amount of functionality from both tools
The I²C proxy specification is not always shared with all other devices as
I originally hoped, instead there are other legacy devices that use different
sets of I²C commands.
Un-share various bits of code to allow for additional I²C devices to be added.
No logic changes.
Write the firmware to the usb device, first finding which section to
write to, then breaking into blocks (based on maximum pdu size),
and then into chunks, which are transferred to the device using bulk transfers.
The register specifications have been taken as a superset of the coreboot
documentation as different flags were documented in more detail on various
different platforms.
Having this new data allows us to add future tests and make the current tests
much easier to understand.
