Semantically it is the desire of the security attribute, not the bios
attribute, i.e. you could imagine that a specific attribute would have
to be *foo or bar or baz* for HSI-1 and *only foo* for HSI-2
Also make it easier to add possible BIOS attribute target values in
plugin code.
This means we don't need to worry about changing multiple
implementations if the HSI levels change for a specific ID.
It also means we can fake HSI results in the future without having
to also store the 'correct' level in the input file.
We tried to solve this by matching the org.fwupd.hsi AppStream ID, but
in some cases the resolution depends on what actually failed.
Add "the action the user is supposed to do" as flags so that the
front-end can translate this in the appropriate way, for instance,
using a different string for log events and HSI dialogs.
We were calling g_module_symbol() 2703 times, which is actually more
expensive than you'd think.
It also means the plugins are actually what we tell people they are:
A set of vfuncs that get run. The reality before that they were dlsym'd
functions that get called at pretty random times.
When this is done, include:
* Including the hash
* Including anything that is not ABI stable in plugins yet
Suggested-by: Simon McVittie <smcv@debian.org>
To do this, rely on the AppStream ID to map to a translated string (providing a
fallback for clients that do not care) and switch the free-form result string
into a set of enumerated values that can be translated.
This fixes some of the problems where some things have to be enabled to "pass"
and other attributes have to be some other state. For cases where we want the
user to "do" something, provide a URL to a wiki page that we update out-of-band
of fwupd releases.
The HSI specification is currently incomplete and in active development.
