bug: 30963384
Change-Id: I62b5ffd43469dbb0bba67e1bb1d3416e7354f9e5

This allows the shell user to control whether unprivileged access to
perf events is allowed.
To enable unprivileged access to perf:
adb shell setprop security.perf_harden 0
To disable it again:
adb shell setprop security.perf_harden 1
This allows Android to disable this kernel attack surface by default,
while still allowing profiling tools to work automatically. It can also
be manually toggled, but most developers won't ever need to do that if
tools end up incorporating this.

SELinux defines various classes for various socket types, including
tcp_socket, udp_socket, rawip_socket, netlink_socket, etc. Socket
classes not known to the SELinux kernel code get lumped into the generic
"socket" class. In particular, this includes the AF_MSM_IPC socket
class.
Bluetooth using apps were granted access to this generic socket class at
one point in 2012. In 1601132086b054adc70e7f8f38ed24574c90bc37,
a TODO was added indicating that this access was likely unnecessary. In
cb835a2852997dde0be2941173f8c879ebbef157, an auditallow was added to
test to see if this rule was actually used, and in master branch
d0113ae0aed1a455834f26ec847b6ca8610e3b16, this rule was completely
deleted.
Revoke access to the generic socket class for isolated_app,
untrusted_app, and shell for older Android releases. This is
conceptually a backport of d0113ae0aed1a455834f26ec847b6ca8610e3b16, but
affecting fewer domains to avoid potential breakage.
Add a neverallow rule asserting that this rule isn't present for the
untrusted domains. Contrary to our usual conventions, the neverallow
rule is placed in bluetooth.te, to avoid merge conflicts and simplify
patching.

Restrict unix_dgram_socket and unix_stream_socket to a whitelist
for all domains. Remove ioctl permission for netlink_selinux_socket and
netlink_route_socket for netdomain.

binderservicedomain services often expose their methods to untrusted
clients and rely on permission checks for access control. Allow these
services to query the permission service for access decisions.

This allows NetworkDiagnostics to send ping packets from specific
source addresses in order to detect reachability problems on the
reverse path.
This addresses the following denial:

CTS relies on the ability to see all services on the system to make sure
the dump permission is properly enforced on all services. Allow this.
