NAME

6       setfiles_mac_selinux  -  Security  Enhanced  Linux  Policy for the set‐
7       files_mac processes
8

DESCRIPTION

10       Security-Enhanced Linux secures the setfiles_mac processes via flexible
11       mandatory access control.
12
13       The  setfiles_mac  processes  execute  with  the setfiles_mac_t SELinux
14       type. You can check if you have these processes  running  by  executing
15       the ps command with the -Z qualifier.
16
17       For example:
18
19       ps -eZ | grep setfiles_mac_t
20

22

ENTRYPOINTS

24       The  setfiles_mac_t SELinux type can be entered via the setfiles_exec_t
25       file type.
26
27       The default entrypoint paths for the setfiles_mac_t domain are the fol‐
28       lowing:
29
30       /sbin/setfiles.*,        /usr/sbin/setfiles.*,        /sbin/restorecon,
31       /usr/sbin/restorecon
32

PROCESS TYPES

34       SELinux defines process types (domains) for each process running on the
35       system
36
37       You can see the context of a process using the -Z option to ps
38
39       Policy  governs  the  access confined processes have to files.  SELinux
40       setfiles_mac policy is very flexible allowing users to setup their set‐
41       files_mac processes in as secure a method as possible.
42
43       The following process types are defined for setfiles_mac:
44
45       setfiles_mac_t
46
47       Note:  semanage  permissive  -a  setfiles_mac_t can be used to make the
48       process type setfiles_mac_t permissive. SELinux does not deny access to
49       permissive  process  types,  but the AVC (SELinux denials) messages are
50       still generated.
51
52

BOOLEANS

54       SELinux policy is customizable based on least  access  required.   set‐
55       files_mac  policy  is  extremely flexible and has several booleans that
56       allow you to manipulate the policy and run setfiles_mac with the tight‐
57       est access possible.
58
59
60
61       If you want to deny user domains applications to map a memory region as
62       both executable and writable, this  is  dangerous  and  the  executable
63       should be reported in bugzilla, you must turn on the deny_execmem bool‐
64       ean. Enabled by default.
65
66       setsebool -P deny_execmem 1
67
68
69
70       If you want to allow all domains to execute in fips_mode, you must turn
71       on the fips_mode boolean. Enabled by default.
72
73       setsebool -P fips_mode 1
74
75
76
77       If  you  want  to control the ability to mmap a low area of the address
78       space, as configured by /proc/sys/vm/mmap_min_addr, you  must  turn  on
79       the mmap_low_allowed boolean. Disabled by default.
80
81       setsebool -P mmap_low_allowed 1
82
83
84
85       If  you  want  to  disable  kernel module loading, you must turn on the
86       secure_mode_insmod boolean. Enabled by default.
87
88       setsebool -P secure_mode_insmod 1
89
90
91
92       If you want to allow unconfined executables to make their  heap  memory
93       executable.   Doing  this  is  a  really bad idea. Probably indicates a
94       badly coded executable, but could indicate an attack.  This  executable
95       should   be   reported  in  bugzilla,  you  must  turn  on  the  selin‐
96       uxuser_execheap boolean. Disabled by default.
97
98       setsebool -P selinuxuser_execheap 1
99
100
101
102       If you want to allow unconfined executables to make  their  stack  exe‐
103       cutable.   This  should  never, ever be necessary. Probably indicates a
104       badly coded executable, but could indicate an attack.  This  executable
105       should  be reported in bugzilla, you must turn on the selinuxuser_exec‐
106       stack boolean. Enabled by default.
107
108       setsebool -P selinuxuser_execstack 1

MANAGED FILES

113       The SELinux process type setfiles_mac_t can manage files  labeled  with
114       the  following  file types.  The paths listed are the default paths for
115       these file types.  Note the processes UID still need to have  DAC  per‐
116       missions.
117
118       file_type
119
120            all files on the system
121
122

COMMANDS

124       semanage  fcontext  can also be used to manipulate default file context
125       mappings.
126
127       semanage permissive can also be used to manipulate  whether  or  not  a
128       process type is permissive.
129
130       semanage  module can also be used to enable/disable/install/remove pol‐
131       icy modules.
132
133       semanage boolean can also be used to manipulate the booleans
134
135
136       system-config-selinux is a GUI tool available to customize SELinux pol‐
137       icy settings.
