Rather than trying to guess typos, force each plugin to register the quirk
keys it supports, so we can show a sensible warning if required at startup on
the console.
The best way of not getting something wrong is to not require it in the first
place...
All plugins now use DeviceInstanceId-style quirk matches and we can just drop
the prefix in all files. We were treating HwId=, Guid= and DeviceInstanceId= in
exactly the same way -- they're just converted to GUIDs when building the silo!
The end year is legally and functionally redundant, and more importantly causes
cherry-pick conflicts when trying to maintain old branches. Use git for history.
The snap-store intends to ship an updated libfwupd library but
to use it with whatever version daemon is on the host system.
This means that the library needs to still work with older metadata
signing types.
This fixes the following error in that scenario:
```Failed to update metadata for lvfs: Keyring kind jcat not supported```
A Jcat file can be used to store GPG, PKCS-7 and SHA-256 checksums for multiple
files. This allows us to sign a firmware or metadata multiple times (perhaps
by the OEM and also then the LVFS) which further decentralizes the trust model
of the LVFS.
The Jcat format was chosen as the Microsoft catalog format is nonfree and not
documented. We also don't want to modify an existing .cat file created from WU
as this may make it unsuitable to use on Windows.

If the measurements are missing but it's a UEFI system, it's a good indication
that the user has secure boot turned off.
Notify the user on the UEFI device through a non-fatal `UpdateMessage`
To accomplish this, move fu-uefi-vars into the plugin library for other plugins to use
Some hardware does not handle upgrading from version 1.2.2 to 1.2.4 and instead
needs to be upgraded from 1.2.2->1.2.3->1.2.4 so that on-device metadata can be
migrated correctly.
Add a new per-device flag `install-all-releases` which causes the daemon to not
skip directly to the newest release. This is designed to be set from a quirk
file.
This can obviously only be used for devices that can apply firmware "live" and
thus do not need a reboot or system shutdown to actually apply the firmware.
This also needs the cabinet archive to ship multiple versions of the firmware,
and for the metainfo.xml file to refer to multiple release objects.
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.
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.
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 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.
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.
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.
If a remote like LVFS outputs <location>foo.cab</location> without a prepended
hostname and path then we should use the metadata URI hostname and path instead.
This allows us to trivially mirror a firmware repository, although clients using
older versions of libfwupd will not work without this patch. We should encourage
people to use `FirmwareBaseURI` for a long time yet.
In the latest version of the LVFS you can restrict the firmware to a specific
machine type, for instance a specific baseboard vendor. This is the same as
done in Microsoft Update using the CHID mechanism.
This commit adds support for the <hardware> requires type, although it needs to
be built against appstream-glib 0.7.4 to be supported and/or tested.
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
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.
According to the crypto experts, path_len=1 makes things more secure for a CA
to prevent the Sub-CAs from issuing further Sub-Sub-CAs. I'll stick to code.
This also switches around the test for the self signed key to now fail, as the
generated certificate is no longer loaded into the trust list. This is a more
useful test as it more accurately represents what the fwupd daemon is doing.
As a side-note the detached signature from the derivate cannot be generated
using `--no-p7-include-cert` as only the main LVFS-CA certificate is shipped
with fwupd.
This means we return an error when encountering a rollback attack. This can
currently be performed by providing the old metadata and old signature when
calling into UpdateMetadata.
We can use this as an alternative for GPG. No PKCS7 certificates are currently
installed by fwupd and it's expected that the LVFS will still only provide GPG
detached signatures.
If an OEM distributor wants to sign firmware with a PKCS7 and the corresponding
certificate is provided then the firmware will be marked as valid.
Only firmware shipping with a .p7b file will use the PKCS7 functionality,
similarly remote metadata validation will default to GPG unless Keyring=pkcs7
is specified in the config file.
