6 systemd_sysctl_selinux - Security Enhanced Linux Policy for the sys‐
7 temd_sysctl processes
8
10 Security-Enhanced Linux secures the systemd_sysctl processes via flexi‐
11 ble mandatory access control.
12 The systemd_sysctl processes execute with the systemd_sysctl_t SELinux
14 type. You can check if you have these processes running by executing
15 the ps command with the -Z qualifier.
16 For example:
18 ps -eZ | grep systemd_sysctl_t
20
24 The systemd_sysctl_t SELinux type can be entered via the sys‐
25 temd_sysctl_exec_t file type.
26 The default entrypoint paths for the systemd_sysctl_t domain are the
28 following:
29 /usr/lib/systemd/systemd-sysctl
31
33 SELinux defines process types (domains) for each process running on the
34 system
35 You can see the context of a process using the -Z option to ps
37 Policy governs the access confined processes have to files. SELinux
39 systemd_sysctl policy is very flexible allowing users to setup their
40 systemd_sysctl processes in as secure a method as possible.
41 The following process types are defined for systemd_sysctl:
43 systemd_sysctl_t
45 Note: semanage permissive -a systemd_sysctl_t can be used to make the
47 process type systemd_sysctl_t permissive. SELinux does not deny access
48 to permissive process types, but the AVC (SELinux denials) messages are
49 still generated.
50
53 SELinux policy is customizable based on least access required. sys‐
54 temd_sysctl policy is extremely flexible and has several booleans that
55 allow you to manipulate the policy and run systemd_sysctl with the
56 tightest access possible.
57 If you want to dontaudit all daemons scheduling requests (setsched,
61 sys_nice), you must turn on the daemons_dontaudit_scheduling boolean.
62 Enabled by default.
63 setsebool -P daemons_dontaudit_scheduling 1
65 If you want to allow all domains to execute in fips_mode, you must turn
69 on the fips_mode boolean. Enabled by default.
70 setsebool -P fips_mode 1
72 If you want to allow system to run with NIS, you must turn on the
76 nis_enabled boolean. Disabled by default.
77 setsebool -P nis_enabled 1

83 The SELinux process type systemd_sysctl_t can manage files labeled with
84 the following file types. The paths listed are the default paths for
85 these file types. Note the processes UID still need to have DAC per‐
86 missions.

143 SELinux requires files to have an extended attribute to define the file
144 type.
145 You can see the context of a file using the -Z option to ls
147 Policy governs the access confined processes have to these files.
149 SELinux systemd_sysctl policy is very flexible allowing users to setup
150 their systemd_sysctl processes in as secure a method as possible.
151 STANDARD FILE CONTEXT
153 SELinux defines the file context types for the systemd_sysctl, if you
155 wanted to store files with these types in a different paths, you need
156 to execute the semanage command to specify alternate labeling and then
157 use restorecon to put the labels on disk.
158 semanage fcontext -a -t systemd_sysctl_exec_t '/srv/systemd_sysctl/con‐
160 tent(/.*)?'
161 restorecon -R -v /srv/mysystemd_sysctl_content
162 Note: SELinux often uses regular expressions to specify labels that
164 match multiple files.
165 The following file types are defined for systemd_sysctl:
167 systemd_sysctl_exec_t
171 - Set files with the systemd_sysctl_exec_t type, if you want to transi‐
173 tion an executable to the systemd_sysctl_t domain.
174 Note: File context can be temporarily modified with the chcon command.
178 If you want to permanently change the file context you need to use the
179 semanage fcontext command. This will modify the SELinux labeling data‐
180 base. You will need to use restorecon to apply the labels.
181
184 semanage fcontext can also be used to manipulate default file context
185 mappings.
186 semanage permissive can also be used to manipulate whether or not a
188 process type is permissive.
189 semanage module can also be used to enable/disable/install/remove pol‐
191 icy modules.
192 semanage boolean can also be used to manipulate the booleans
194 system-config-selinux is a GUI tool available to customize SELinux pol‐
197 icy settings.
