Subject: [PATCH 0/1]  selinux-testsuite: Add perf_event tests
Date: Sun,  1 Dec 2019 14:52:37 +0000	[thread overview]
Message-ID: <20191201145238.265621-1-richard_c_haines@btinternet.com> (raw)

This was tested on kernel.org 'next-20191128' as Rawhide kernels
don't yet support the new perf_event hooks.

Note that the default .config enables the following that have been added
to defconfig:
CONFIG_HAVE_PERF_EVENTS=y
CONFIG_PERF_EVENTS=y
CONFIG_TRACEPOINTS=y

To allow testing, the following steps are required to update Fedora
policy:

1) Using the diff below, add the perf_event class and its
   permissions to:
/usr/share/selinux/devel/include/support/all_perms.spt

 	class smc_socket all_smc_socket_perms;
 	class bpf all_bpf_perms;
 	class xdp_socket all_xdp_socket_perms;
+	class perf_event { open cpu kernel tracepoint read write };
 ')
 
 define(`all_userspace_class_perms',`


2) Create a cil module 'test_perf.cil' that defines the class:

(class perf_event (open cpu kernel tracepoint read write))
(classorder (unordered perf_event))

Then insert into policy:
semodule -i test_perf.cil
