When an app is proxying access to runtime permission protected
data it needs to check whether the calling app has a permission
to the data it is about to proxy which leaves a trace in app ops
that the requesting app perofmed a data access. However, then the
app doing the work needs to get the protected data itself from the
OS which access gets attributed only to itself. As a result there
are two data accesses in app ops where only the first one is a
proxy one that app A got access to Foo through app B - that is the
one we want to show in the permission tracking UIs - and one
for the data access - that is the one we would want to blame on
the calling app, and in fact, these two accesses should be one -
that app A accessed Foo though B. This limitation requires fragile
one off workarounds where both accesses use the same attribution
tag and sys UI has hardcoded rules to dedupe. Since this is not
documented we cannot expect that the ecosystem would reliably
do this workaround in apps that that the workaround in the OS
would be respected by every OEM.
This change adds a mechaism to resolve this issue. It allows for
an app to create an attribution context for another app and then
any private data access thorugh this context would result in a
single app op blame that A accessed Foo though B, i.e. we no longer
have double accounting. Also this can be nested through apps, e.g.
app A asks app B which asks app C for contacts. In this case app
B creates an attribution context for app A and calls into app C
which creates an attribution context for app B. When app C gets
contacts the entire attribution chain would get a porper, single
blame: that C accessed the data, that B got the data from C, and
that A got the data form B. Furthermore, this mechanism ensures
that apps cannot forget to check permissions for the caller
before proxying private data. In our example B and C don't need
to check the permisisons for A and B, respectively, since the
permisisons for the entire attribution chain are checked before
data delivery. Attribution chains are not forgeable preventing
a bad actor to create an arbitrary one - each attribution is
created by the app it refers to and points to a chain of
attributions created by their corresponding apps.
This change also fixes a bug where all content provider accesses
were double counted in app ops due to double noting. While at
this it also fixes that apps can now access their own last ops.
There was a bug where one could not pass null getting the attributed
ops from a historical package ops while this is a valid use case
since if there is no attribution everything is mapped to the null
tag. There were some app op APIs not being piped thorough the app
ops delegate and by extension through the app ops policy. Also
now that we have nice way to express the permission chain in a
call we no longer need the special casing in activity manager to
handle content provider accesses through the OS. Fixed a bug
where we don't properly handle the android.os.shell calls with
an invlaid tag which was failing while the shell can do any tag.
Finally, to ensure the mechanims is validated and works end-to-end
we are adding support for a voice recognizer to blame the client
app for the mic access. The recognition service can create a blaming
context when opening the mic and if the mic is open, which would
do all permission checks, we would not do so again. Since changes
to PermissionChercker for handling attribution sources were made
the CL also hooks up renounced permissoins in the request permission
flow and in the permission checks.

These feature flags will hold the KeyMint version for the default and
StrongBox HALs. They can be used by apps to convey that they'll only
work on devices which have a recent enough version of KeyMint.
For example, if an application requires ECDH to be implemented in
Secure Hardware it can convey this requirement by indicated that it
needs FEATURE_HARDWARE_KEYSTORE >= 100. Or if it needs this in the
StrongBox it can use FEATURE_STRONGBOX_KEYSTORE >= 100. As with other
feature flags, this can be used to only show the app on devices which
satisfy such requirements.
