      Remove generic socket access from untrusted processes · abf0663e
      Nick Kralevich authored 
      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 16011320,
a TODO was added indicating that this access was likely unnecessary. In
cb835a28, an auditallow was added to
test to see if this rule was actually used, and in master branch
d0113ae0, 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 d0113ae0, 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

      Enable permission checking by binderservicedomain. · 9acda2f3
      dcashman authored 
      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.

      Allow system_server to bind ping sockets. · 16c36f68
      Lorenzo Colitti authored 
      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:

[  209.744636] type=1400 audit(1441805730.510:14): avc: denied { node_bind } for pid=8347 comm="Thread-202" saddr=2400:xxxx:xxxx:xxxx:40b1:7e:a1d7:b3ae scontext=u:r:system_server:s0 tcontext=u:object_r:node:s0 tclass=rawip_socket permissive=0

      Allow untrusted_app to list services. · 0b764ae9
      dcashman authored 
      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.
