6 systemd_tmpfiles_selinux - Security Enhanced Linux Policy for the sys‐
7 temd_tmpfiles processes
8
10 Security-Enhanced Linux secures the systemd_tmpfiles processes via
11 flexible mandatory access control.
12
13 The systemd_tmpfiles processes execute with the systemd_tmpfiles_t
14 SELinux type. You can check if you have these processes running by exe‐
15 cuting the ps command with the -Z qualifier.
16
17 For example:
18
19 ps -eZ | grep systemd_tmpfiles_t
20
21
22
24 The systemd_tmpfiles_t SELinux type can be entered via the systemd_tmp‐
25 files_exec_t file type.
26
27 The default entrypoint paths for the systemd_tmpfiles_t domain are the
28 following:
29
30 /bin/systemd-tmpfiles, /usr/bin/systemd-tmpfiles, /usr/lib/systemd/sys‐
31 temd-tmpfiles
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 systemd_tmpfiles policy is very flexible allowing users to setup their
41 systemd_tmpfiles processes in as secure a method as possible.
42
43 The following process types are defined for systemd_tmpfiles:
44
45 systemd_tmpfiles_t
46
47 Note: semanage permissive -a systemd_tmpfiles_t can be used to make the
48 process type systemd_tmpfiles_t permissive. SELinux does not deny
49 access to permissive process types, but the AVC (SELinux denials) mes‐
50 sages are still generated.
51
52
54 SELinux policy is customizable based on least access required. sys‐
55 temd_tmpfiles policy is extremely flexible and has several booleans
56 that allow you to manipulate the policy and run systemd_tmpfiles with
57 the tightest access possible.
58
59
60
61 If you want to allow users to resolve user passwd entries directly from
62 ldap rather then using a sssd server, you must turn on the authlo‐
63 gin_nsswitch_use_ldap boolean. Disabled by default.
64
65 setsebool -P authlogin_nsswitch_use_ldap 1
66
67
68
69 If you want to allow all domains to execute in fips_mode, you must turn
70 on the fips_mode boolean. Enabled by default.
71
72 setsebool -P fips_mode 1
73
74
75
76 If you want to allow confined applications to run with kerberos, you
77 must turn on the kerberos_enabled boolean. Enabled by default.
78
79 setsebool -P kerberos_enabled 1
80
81
82
83 If you want to allow system to run with NIS, you must turn on the
84 nis_enabled boolean. Disabled by default.
85
86 setsebool -P nis_enabled 1
87
88
89
90 If you want to allow confined applications to use nscd shared memory,
91 you must turn on the nscd_use_shm boolean. Disabled by default.
92
93 setsebool -P nscd_use_shm 1
94
95
96
98 The SELinux process type systemd_tmpfiles_t can manage files labeled
99 with the following file types. The paths listed are the default paths
100 for these file types. Note the processes UID still need to have DAC
101 permissions.

205 SELinux requires files to have an extended attribute to define the file
206 type.
207
208 You can see the context of a file using the -Z option to ls
209
210 Policy governs the access confined processes have to these files.
211 SELinux systemd_tmpfiles policy is very flexible allowing users to set‐
212 up their systemd_tmpfiles processes in as secure a method as possible.
213
214 The following file types are defined for systemd_tmpfiles:
215
216
217
218 systemd_tmpfiles_exec_t
219
220 - Set files with the systemd_tmpfiles_exec_t type, if you want to tran‐
221 sition an executable to the systemd_tmpfiles_t domain.
222
223
224 Paths:
225 /bin/systemd-tmpfiles, /usr/bin/systemd-tmpfiles, /usr/lib/sys‐
226 temd/systemd-tmpfiles
227
228
229 Note: File context can be temporarily modified with the chcon command.
230 If you want to permanently change the file context you need to use the
231 semanage fcontext command. This will modify the SELinux labeling data‐
232 base. You will need to use restorecon to apply the labels.
233
234
236 semanage fcontext can also be used to manipulate default file context
237 mappings.
238
239 semanage permissive can also be used to manipulate whether or not a
240 process type is permissive.
241
242 semanage module can also be used to enable/disable/install/remove pol‐
243 icy modules.
244
245 semanage boolean can also be used to manipulate the booleans
246
247
248 system-config-selinux is a GUI tool available to customize SELinux pol‐
249 icy settings.
