Test: build aosp_sailfish
Change-Id: Iaefe1df66885d3e78feb600c3d9845bd9fe671a2

Prior to this CL, /sys/devices/virtual/block/dm-X was using the generic
sysfs label. This CL creates sysfs_dm label and grants the following
accesses:
 - update_verifier to read sysfs_dm dir and file at
   /sys/devices/virtual/block/dm-X.
 - vold to write sysfs_dm.

Bug: 63440407
Test: update_verifier successfully triggers blocks verification and
      marks a sucessful boot;
Test: No sysfs_dm related denials on sailfish.

isolated_apps are intended to be strictly limited in the /sys files
which can be read. Add a neverallow assertion to guarantee this on all
Android compatible devices.

Test: policy compiles.

Comments indicate that these permissions are used to access already
open FDs. However, getattr of a directory is clearly not necessary
for that, search of system_data_file is already granted to domain
and following symlinks is clearly not needed for reading an already
open FD.

Test: boot marlin. Test drm with google play movies, no related
    denials
Test: cts-tradefed run cts -m CtsMediaTestCases -t \

    5/6 tests fail with no related selinux denials. The same 5/6
    also fail in selinux permissive mode.

Bullhead and dragon are broken. Revert until I can fix
those builds.

Test: policy compiles.

Mediaextractor should only be operating on data passed directly to it.
It shouldn't be attempting to open /data files on it's own.

Add a neverallow statement (compile time assertion + CTS test) to ensure
this is the case.

Renamed this type:
proc_asound_cards -> proc_asound

Labeled /proc/asound/devices as proc_asound.

We now use proc_asound type to label files under /proc/asound which we
want to expose to system components.

Bug: 66988327
Test: Pixel 2 boots, can play sound with or without headphones, and
selinux denials to proc_asound are not seen.

On Marlin/Sailfish, StorageManager tests in CTS are exposing a bug
where the /proc/<pid>/ns/mnt files for system_server are briefly
mislabeled as "proc" instead of "system_server". Resulting in the
tests failing. Temporarily re-granting access to the default label
until the labeling issue can be tracked down.
