6 setfiles_mac_selinux - Security Enhanced Linux Policy for the set‐
7 files_mac processes
8
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
21
22
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
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
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

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

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
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.
