It seems some older versions of libefi var incorrectly build the 'length' value
in the DP returned from efi_generate_file_device_path(). This means we copy past
the end of the allocated buffer when parsing the efi_update_info_t structure.
This bug seems fixed in efivar git master, and this fix is only going to help
people with older efivar versions. It's probably a good thing to be a bit more
paranoid about EFI variable data anyway.

Adding a new plugin
An extensible architecture allows for providing new plugin types (for reading and writing different firmware) as well as ways quirk their behavior.
You can find more information about the architecture in the developers section of the fwupd website.
If you have a firmware specification and would like to see support in this project, please file an issue and share the spec. Patches are also welcome.
We will not accept plugins that upgrade hardware using a proprietary Linux executable, library, or DBus interface.
Plugin interaction
Some plugins may be able to influence the behavior of other plugins. This includes things like one plugin turning on a device, or providing missing metadata to another plugin.
The ABI for these interactions is defined in: https://github.com/hughsie/fwupd/blob/master/src/fu-device-metadata.h
All interactions between plugins should have the interface defined in that file.
