Define extended_socket_class policy capability and socket classes Add a definition for the extended_socket_class policy capability used to enable the use of separate socket security classes for all network address families rather than the generic socket class. The capability also enables the use of separate security classes for ICMP and SCTP sockets, which were previously mapped to rawip_socket class. Add definitions for the new socket classes and access vectors enabled by this capability. Add the new socket classes to the socket_class_set macro, and exclude them from webview_zygote domain as with other socket classes. Allowing access by specific domains to the new socket security classes is left to future commits. Domains previously allowed permissions to the 'socket' class will require permission to the more specific socket class when running on kernels with this support. The kernel support will be included upstream in Linux 4.11. The relevant kernel commits are da69a5306ab92e07224da54aafee8b1dccf024f6 ("selinux: support distinctions among all network address families"), ef37979a2cfa3905adbf0c2a681ce16c0aaea92d ("selinux: handle ICMPv6 consistently with ICMP"), and b4ba35c75a0671a06b978b6386b54148efddf39f ("selinux: drop unused socket security classes"). This change requires selinux userspace commit d479baa82d67c9ac56c1a6fa041abfb9168aa4b3 ("libsepol: Define extended_socket_class policy capability") in order to build the policy with this capability enabled. This commit is already in AOSP master. Test: policy builds Change-Id: I788b4be9f0ec0bf2356c0bbef101cd42a1af49bb Signed-off-by: Stephen Smalley <sds@tycho.nsa.gov> 2016-12-08 10:35:27 -08:00
