Three properties are declared as vendor-init-settable:
ro.media.xml_variant.codecs
ro.media.xml_variant.codecs_performance
ro.media.xml_variant.profiles
media_codecs.xml can now be named
media_codecs${ro.media.xml_variant.codecs}.xml
media_codecs_performance.xml can now be named
media_codecs_performance${ro.media.xml_variant.codecs_performance}.xml
media_profiles_V1_0 can now be named
media_profiles${ro.media.xml_variant.profiles}.xml
Test: Rename "media_codecs.xml" to "media_codecs_test.xml",
set ro.media.xml_variant.codecs to "_test", then
call "stagefright -i".
Test: Rename "media_codecs_performance.xml" to
"media_codecs_performance_test.xml",
set ro.media.xml_variant.codecs_performance to "_test", then
run android.media.cts.VideoDecoderPerfTest.
Test: Rename "media_profiles_V1_0.xml" to "media_profiles_test.xml",
set ro.media.xml_variant.profiles to "_test", then
run vts_mediaProfiles_validate_test.

This grants default access to the new GNSS subsystem for Linux to the
GNSS HAL default implementation. The GNSS subsystem creates character
devices similar to ttys but without much unneeded complexity. The GNSS
device class is specific to location use cases.

This property type represents properties used in CTS tests of userspace
reboot. For example, test.userspace_reboot.requested property which is
used to check that userspace reboot was successful and didn't result in
full reboot, e.g.:
* before test setprop test.userspace_reboot.requested 1
* adb reboot userspace
* wait for boot to complete
* verify that value of test.userspace_reboot.requested is still 1
Test: adb shell setprop test.userspace_reboot.requested 1

(cherry picked from commit 3bd53a9cee)
See discussion in aosp/1233645. There was a concern about this
filesystem automounting when enabled, so this change adds sepolicy to
preemptively lock it down.
I'm not confident it actually automounts. If it does, it'll land in
/sys/kernel/security, which is also protected with the sysfs policy.

* allow shell to enable/disable the daemon via a sysprop
* don't audit signals, as some denials are expected
* exclude zygote from the profileable set of targets on debug builds.
I've not caught any crashes in practice, but believe there's a
possibility that the zygote forks while holding a non-whitelisted fd
due to the signal handler.

Define two property_context.
1. vendor_socket_hook_prop - for ro.vendor.redirect_socket_calls. The
property set once in vendor_init context. It's evaluated at process
start time and is cannot change at runtime on a given device. The set
permission is restricted to vendor_init. The read permission is
unrestricted.
2. socket_hook_prop - for net.redirect_socket_calls.hooked. The
property can be changed by System Server at runtime. It's evaluated when
shimmed socket functions is called. The set permission is restricted to
System Server. The read permission is unrestricted.

Setting files and dirs under /data/incremental as apk_data_file, so that
they will have the same permissions as the ones under /data/app.
Current layout of the dirs:
1. /data/incremental/[random]/mount -> holds data files (such as base.apk) and
control files (such as .cmd). Its subdirectory is first bind-mounted to
/data/incremental/tmp/[random], eventually bind-mounted to
/data/app/~~[randomA]/[packageName]-[randomB].
2. /data/incremental/[random]/backing_mount -> hold incfs backing image.
3. /data/incremental/tmp/[random] -> holds temporary mountpoints (bind-mount targets)
during app installation.

/mnt/pass_through was introduced to allow the FUSE daemon unrestricted
access to the lower filesystem (or sdcardfs).
At zygote fork time, the FUSE daemon will have /mnt/pass_through/0
bind mounted to /storage instead of /mnt/user/0. To keep /sdcard
(symlink to /storage/self/primary) paths working, we create a
'self' directory with an additional 'primary' symlink to
/mnt/pass_through/0/emulated/0 which is a FUSE mount point.
The following components need varying sepolicy privileges:
Vold: Creates the self/primary symlink and mounts the lower filesystem
on /mnt/pass_through/0/emulated. So needs create_dir and mount access
+ create_file access for the symlink
zygote: In case zygote starts an app before vold sets up the paths.
This is unlikely but can happen if the FUSE daemon (a zygote forked app)
is started before system_server completes vold mounts.
Same sepolicy requirements as vold
installd: Needs to clear/destroy app data using lower filesystem
mounted on /mnt/pass_through so needs read_dir access to walk
/mnt/pass_through
priv_app (FUSE daemon): Needs to server content from the lower
filesystem mounted on /mnt/pass_through so needs read_dir access to
walk /mnt/pass_through
Bug: 135341433
Test: adb shell ls /mnt/pass_through/0/self/primary

The steps involved in setting up profiling and stack unwinding are
described in detail at go/perfetto-perf-android.
To summarize the interesting case: the daemon uses cpu-wide
perf_event_open, with userspace stack and register sampling on. For each
sample, it identifies whether the process is profileable, and obtains
the FDs for /proc/[pid]/{maps,mem} using a dedicated RT signal (with the
bionic signal handler handing over the FDs over a dedicated socket). It
then uses libunwindstack to unwind & symbolize the stacks, sending the
results to the central tracing daemon (traced).
This patch covers the app profiling use-cases. Splitting out the
"profile most things on debug builds" into a separate patch for easier
review.
Most of the exceptions in domain.te & coredomain.te come from the
"vendor_file_type" allow-rule. We want a subset of that (effectively all
libraries/executables), but I believe that in practice it's hard to use
just the specific subtypes, and we're better off allowing access to all
vendor_file_type files.
