racoon policy. Initial policy for racoon (IKE key management). Signed-off-by: Robert Craig <rpcraig@tycho.ncsc.mil> Change-Id: If1e344f39ea914e42afbaa021b272ba1b7113479

# IKE key management daemon
Create attribute for moving perms out of domain Motivation: Domain is overly permissive. Start removing permissions from domain and assign them to the domain_deprecated attribute. Domain_deprecated and domain can initially be assigned to all domains. The goal is to not assign domain_deprecated to new domains and to start removing domain_deprecated where it is not required or reassigning the appropriate permissions to the inheriting domain when necessary.

Clean up socket rules. Replace * or any permission set containing create with create_socket_perms or create_stream_socket_perms. Add net_domain() to all domains using network sockets and delete rules already covered by domain.te or net.te. For netlink_route_socket, only nlmsg_write needs to be separately granted to specific domains that are permitted to modify the routing table. Clarification: read/write permissions are just ability to perform read/recv() or write/send() on the socket, whereas nlmsg_read/ nlmsg_write permissions control ability to observe or modify the underlying kernel state accessed via the socket. See security/selinux/nlmsgtab.c in the kernel for the mapping of netlink message types to nlmsg_read or nlmsg_write. Delete legacy rule for b/12061011. This change does not touch any rules where only read/write were allowed to a socket created by another domain (inherited across exec or received across socket or binder IPC). We may wish to rewrite some or all of those rules with the rw_socket_perms macro but that is a separate change.

Deduplicate binder_call rules. A number of binder_call rules are duplicated by other rules written in terms of attributes/sets (e.g. appdomain, binderservicedomain). Get rid of the duplicates. Also use binder_use() in racoon.te rather than manually writing the base rule for communicating with the servicemanager.

Enforce ioctl command whitelisting on all sockets Remove the ioctl permission for most socket types. For others, such as tcp/udp/rawip/unix_dgram/unix_stream set a default unprivileged whitelist that individual domains may extend (except where neverallowed like untrusted_app). Enforce via a neverallowxperm rule. Change-Id: I15548d830f8eff1fd4d64005c5769ca2be8d4ffe

Adding policies for KeyStore MAC. Add keystore_key class and an action for each action supported by keystore. Add policies that replicate the access control that already exists in keystore.
