All domains using libbinder need access to this new ioctl in order to
pull precise information upon failed binder operations.

Tested: clients can now use the ioctl through libbinder

We've got a SELinux warning in kernel-5.10 when "File Transfer" (MTP)
has been enabled by user.
Error log:
avc: denied { ioctl } for pid=5521 comm="MtpServer" path="/dev/usb-ffs/mtp/ep1" dev="functionfs" ino=102677 ioctlcmd=0x67e7 scontext=u:r:mediaprovider:s0:c512,c768 tcontext=u:object_r:functionfs:s0 tclass=file permissive=0
Repeat steps:
1. Connect the phone to PC with USB cable.
2. Select "File Transfer" (MTP) in "USB Preferences" Menu.
3. Selinux warning will arise after "File Transfer" has been enabled by user
due to an IOCTL access to /dev/usb-ffs/mtp/ep1.
Solution:
To solve this warning, add a sepolicy to allow this type of IOCTL is required.

IncFS in S adds a bunch of new ioctls, and requires the users
to read its features in sysfs directory. This change adds
all the features, maps them into the processes that need to
call into them, and allows any incfs user to query the features

the new ioctl allows system server to verfiry the state of a frozen
binder inderface before unfreezing a process.

BINDER_FREEZE is used to block ipc transactions to frozen processes, so
only system_server must be allowed to use it.
Bug: 143717177
Test: manually verified that attempts to use BINDER_FREEZE by processes
other
than system_server receive a sepolicy denial
Test: verified that system_server can enable/disable the freezer in
binder

allowed to use any of the fscrypt ioctls.

Allow the shell domain to use the FS_IOC_GET_ENCRYPTION_POLICY and
FS_IOC_GET_ENCRYPTION_POLICY_EX ioctls so that we can write a CTS test
which checks that the device complies with the CDD requirements to use
appropriate algorithms for file-based encryption.
The information returned by these ioctls is already available in logcat,
but scraping the log for a CTS test seems fragile; I assume that people
would prefer a more robust solution.
For more details see change I9082241066cba82b531e51f9a5aec14526467162

The original fs-verity implementation requires CAP_SYS_ADMIN and thus
the actual setup is proxied through installd. Instead, upstream
FS_IOC_ENABLE_VERITY ioctl checks write permission to inode, and thus
can happen in system_server.
Also, replace the old measure ioctl with FS_IOC_SET_VERITY_MEASUREMENT.
Note that although the number is name, they work differently.
Test: set ro.apk_verity.mode=2, in-progress CTS passed without denial

Sort file by ioctl name. This will make it hopefully easier to find
entries.
Alternatives considered: sorting file by ioctl value. This has the
advantage that it's easier to map an SELinux ioctlcmd= avc message into
a variable name, but would otherwise make this file harder to read.
Test: policy compiles.

Divide policy into public and private components. This is the first
step in splitting the policy creation for platform and non-platform
policies. The policy in the public directory will be exported for use
in non-platform policy creation. Backwards compatibility with it will
be achieved by converting the exported policy into attribute-based
policy when included as part of the non-platform policy and a mapping
file will be maintained to be included with the platform policy that
maps exported attributes of previous versions to the current platform
version.
Eventually we would like to create a clear interface between the
platform and non-platform device components so that the exported policy,
and the need for attributes is minimal. For now, almost all types and
avrules are left in public.
Test: Tested by building policy and running on device.
