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.
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.
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.
* 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 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.
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.

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).
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.
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.
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.
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.

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.
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.
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);

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).
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.
/boot is a special cased directory when using ProtectSystem=full
Due to this, it's marked read only even if it's listed in ReadWritePaths.
Allow folks to use this for their ESP, but they need to create /boot/EFI
in advance of starting fwupd.
Additionally, if the user specified something invalid, do not autodetect the
ESP but return with a journal error. It seems wrong to ignore what the user
explicitly set and perhaps do something dangerous.
Alternative to https://github.com/hughsie/fwupd/pull/599
Previously if missing secure boot binaries, or invalid ESP was created the
plugin would just not load.
Now instead populate UpdateError and remove the updateble flag, but still show
the device in fwupdmgr and fwupdtool.
1) Drop the path at the end of the title (\fwupdx64.efi)
2) Linux-Firmware-Updater to Linux Firmware Updater
The behavior that required the hacky name has been fixed since shim 10
which is in all the relevant distros now.

Check across a list of common EFI system partition locations for a mounted
location before starting fwupd.
This also will cause the plugin to not initialize if the EFI system partition
is not mounted.
If the user is using some super-old kernel or broken system we want to return
early with an error rather than try to catch each way this can fail at runtime.
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.
Using just the default GUID is fragile and might break if the GUIDs get added
in the 'wrong' order or if the GUID list is sorted.
Fixes https://github.com/hughsie/fwupd/issues/518
Several places in the UEFI plugin operate on the default GUID rather
than iterating a list of GUIDs. This is normally fine since UEFI
GUIDs are tied to the ESRT and normally one FuDevice shouldn't
have multiple GUIDs.
The alternate GUID was added to set parents accordingly but this
caused no CAB files to be able to install.
Fixes: cc664d7d (amt: Put the AMT device as a child under the system UEFI firmware)
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.
