SHA256 with ECDSA on the NIST P-256 curve.

Do not change ownership on /sys/fs/selinux/enforce.

There is no longer any reason to permit system UID to set enforcing mode.

Run the console service shell in the shell domain.

This allows it to be permissive in userdebug/eng builds
but confined/enforcing in user builds.

Apply strict SELinux checking of PROT_EXEC on mmap/mprotect calls.

If checkreqprot == 1, SELinux only checks the protection flags passed
by the application, even if the kernel internally adds PROT_EXEC for
READ_IMPLIES_EXEC personality flags.  Switch to checkreqprot == 0
to check the final protection flags applied by the kernel.

Set security context of /adb_keys and /data/misc/adb/adb_keys.

I97b3d86a69681330bba549491a2fb39df6cf20ef introduced a separate type
for the adb_keys file.  Set the security context of the adb_keys file
accordingly by adding restorecon commands to init.rc.

Move restorecon and restorecon_recursive code to libselinux.

This requires telling libselinux to use the sehandle already
obtained by init rather than re-acquiring it internally.  init
retains ownership of the sehandle because it performs the
initial load, uses the sehandle for other purposes (e.g. labeling
of directories created via mkdir and labeling of socket files),
and handles the policy reload property trigger.

Move creation of /data/misc/wifi and /data/misc/dhcp to main init.rc file.

mkdir /data/misc/wifi subdirectories and /data/misc/dhcp is performed
in the various device-specific init*.rc files but seems generic.
Move it to the main init.rc file.

Drop the separate chown for /data/misc/dhcp as this is handled by mkdir
built-in if the directory already exists.

Add a restorecon_recursive /data/misc/wifi/sockets.

Trigger a policy reload from post-fs-data.

Once userdata is available and decrypted, trigger a policy reload to pick
up any policy update files stored under /data/security.

Apply restorecon_recursive to all of /data.

With the following prior changes:
I77bf2a0c4c34b1feef6fdf4d6c3bd92dbf32f4a1

it should now be safe (will correctly label all files)
and reasonably performant (will skip processing unless
file_contexts has changed since the last call) to call
restorecon_recursive /data from init.rc.

The call is placed after the setprop selinux.policy_reload 1 so that
we use any policy update under /data/security if present.

Revert "toolbox: Add levelFromUid categorization support to restorecon"

This reverts commit 679e2100087be07878a506ff0f7748a32811a40d.

Unify toolbox restorecon and libselinux restorecon implementations.

Extend the libselinux restorecon implementation to allow reuse
by the toolbox restorecon command.  This simply requires adding
support for the nochange (-n) and verbose (-v) options to the
libselinux functions and rewriting the toolbox restorecon command
to use the libselinux functions.   Also add a force (-F) option to
support forcing a restorecon_recursive even if the restorecon_last
attribute matches the current file_contexts hash so that we can
continue to force a restorecon via the toolbox command for testing
or when we know something else has changed (e.g. for when we support
relabeling /data/data and package information has changed).

Convert all selinux_android_restorecon and _setfilecon calls to new API.

libselinux selinux_android_restorecon API is changing to the more
general interface with flags and dropping the older variants.

Also get rid of the old, no longer used selinux_android_setfilecon API
and rename selinux_android_setfilecon2 to it as it is the only API in use.

Handle policy reloads within ueventd rather than restarting it.

Restarting ueventd upon policy reloads has reportedly created
stability problems for some users and could cause events to be lost.
Stop restarting ueventd and instead handle policy reloads within ueventd.

Also stops restarting installd upon policy reloads.
