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 control the ability to mmap a low area  of  the  address
71       space,  as  configured  by /proc/sys/vm/mmap_min_addr, you must turn on
72       the mmap_low_allowed boolean. Disabled by default.
73
74       setsebool -P mmap_low_allowed 1
75
76
77
78       If you want to disable kernel module loading,  you  must  turn  on  the
79       secure_mode_insmod boolean. Enabled by default.
80
81       setsebool -P secure_mode_insmod 1
82
83
84
85       If  you  want to allow unconfined executables to make their heap memory
86       executable.  Doing this is a really  bad  idea.  Probably  indicates  a
87       badly  coded  executable, but could indicate an attack. This executable
88       should  be  reported  in  bugzilla,  you  must  turn  on   the   selin‐
89       uxuser_execheap boolean. Disabled by default.
90
91       setsebool -P selinuxuser_execheap 1
92
93
94
95       If  you  want  to allow unconfined executables to make their stack exe‐
96       cutable.  This should never, ever be necessary.  Probably  indicates  a
97       badly  coded  executable, but could indicate an attack. This executable
98       should be reported in bugzilla, you must turn on the  selinuxuser_exec‐
99       stack boolean. Disabled by default.
100
101       setsebool -P selinuxuser_execstack 1

MANAGED FILES

106       The  SELinux  process type setfiles_mac_t can manage files labeled with
107       the following file types.  The paths listed are the default  paths  for
108       these  file  types.  Note the processes UID still need to have DAC per‐
109       missions.
110
111       file_type
112
113            all files on the system
114
115

COMMANDS

117       semanage fcontext can also be used to manipulate default  file  context
118       mappings.
119
120       semanage  permissive  can  also  be used to manipulate whether or not a
121       process type is permissive.
122
123       semanage module can also be used to enable/disable/install/remove  pol‐
124       icy modules.
125
126       semanage boolean can also be used to manipulate the booleans
127
128
129       system-config-selinux is a GUI tool available to customize SELinux pol‐
130       icy settings.
