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 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 For example:
18 ps -eZ | grep systemd_tmpfiles_t
20
24 The systemd_tmpfiles_t SELinux type can be entered via the systemd_tmp‐
25 files_exec_t file type.
26 The default entrypoint paths for the systemd_tmpfiles_t domain are the
28 following:
29 /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 You can see the context of a process using the -Z option to ps
38 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 The following process types are defined for systemd_tmpfiles:
44 systemd_tmpfiles_t
46 Note: semanage permissive -a systemd_tmpfiles_t can be used to make the
48 process type systemd_tmpfiles_t permissive. SELinux does not deny ac‐
49 cess to permissive process types, but the AVC (SELinux denials) mes‐
50 sages are still generated.
51
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 If you want to dontaudit all daemons scheduling requests (setsched,
62 sys_nice), you must turn on the daemons_dontaudit_scheduling boolean.
63 Enabled by default.
64 setsebool -P daemons_dontaudit_scheduling 1
66 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 setsebool -P fips_mode 1
73 If you want to allow system to run with NIS, you must turn on the
77 nis_enabled boolean. Disabled by default.
78 setsebool -P nis_enabled 1

84 The SELinux process type systemd_tmpfiles_t can manage files labeled
85 with the following file types. The paths listed are the default paths
86 for these file types. Note the processes UID still need to have DAC
87 permissions.

144 SELinux requires files to have an extended attribute to define the file
145 type.
146 You can see the context of a file using the -Z option to ls
148 Policy governs the access confined processes have to these files.
150 SELinux systemd_tmpfiles policy is very flexible allowing users to
151 setup their systemd_tmpfiles processes in as secure a method as possi‐
152 ble.
153 STANDARD FILE CONTEXT
155 SELinux defines the file context types for the systemd_tmpfiles, if you
157 wanted to store files with these types in a different paths, you need
158 to execute the semanage command to specify alternate labeling and then
159 use restorecon to put the labels on disk.
160 semanage fcontext -a -t systemd_tmpfiles_exec_t '/srv/systemd_tmp‐
162 files/content(/.*)?'
163 restorecon -R -v /srv/mysystemd_tmpfiles_content
164 Note: SELinux often uses regular expressions to specify labels that
166 match multiple files.
167 The following file types are defined for systemd_tmpfiles:
169 systemd_tmpfiles_exec_t
173 - Set files with the systemd_tmpfiles_exec_t type, if you want to tran‐
175 sition an executable to the systemd_tmpfiles_t domain.
176 Paths:
179 /bin/systemd-tmpfiles, /usr/bin/systemd-tmpfiles, /usr/lib/sys‐
180 temd/systemd-tmpfiles
181 Note: File context can be temporarily modified with the chcon command.
184 If you want to permanently change the file context you need to use the
185 semanage fcontext command. This will modify the SELinux labeling data‐
186 base. You will need to use restorecon to apply the labels.
187
190 semanage fcontext can also be used to manipulate default file context
191 mappings.
192 semanage permissive can also be used to manipulate whether or not a
194 process type is permissive.
195 semanage module can also be used to enable/disable/install/remove pol‐
197 icy modules.
198 semanage boolean can also be used to manipulate the booleans
200 system-config-selinux is a GUI tool available to customize SELinux pol‐
203 icy settings.
