6 netlabel_mgmt_selinux - Security Enhanced Linux Policy for the netla‐
7 bel_mgmt processes
8
10 Security-Enhanced Linux secures the netlabel_mgmt processes via flexi‐
11 ble mandatory access control.
12 The netlabel_mgmt processes execute with the netlabel_mgmt_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 netlabel_mgmt_t
20
24 The netlabel_mgmt_t SELinux type can be entered via the netla‐
25 bel_mgmt_exec_t file type.
26 The default entrypoint paths for the netlabel_mgmt_t domain are the
28 following:
29 /sbin/netlabelctl, /usr/sbin/netlabelctl, /usr/sbin/netlabel-config
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 netlabel_mgmt policy is very flexible allowing users to setup their
40 netlabel_mgmt processes in as secure a method as possible.
41 The following process types are defined for netlabel_mgmt:
43 netlabel_mgmt_t
45 Note: semanage permissive -a netlabel_mgmt_t can be used to make the
47 process type netlabel_mgmt_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. netla‐
54 bel_mgmt policy is extremely flexible and has several booleans that
55 allow you to manipulate the policy and run netlabel_mgmt with the
56 tightest access possible.

90 default.
91 setsebool -P deny_ptrace 1
93 If you want to allow any process to mmap any file on system with
97 attribute file_type, you must turn on the domain_can_mmap_files bool‐
98 ean. Enabled by default.
99 setsebool -P domain_can_mmap_files 1
101 If you want to allow all domains write to kmsg_device, while kernel is
105 executed with systemd.log_target=kmsg parameter, you must turn on the
106 domain_can_write_kmsg boolean. Disabled by default.
107 setsebool -P domain_can_write_kmsg 1
109 If you want to allow all domains to use other domains file descriptors,
113 you must turn on the domain_fd_use boolean. Enabled by default.
114 setsebool -P domain_fd_use 1
116 If you want to allow all domains to have the kernel load modules, you
120 must turn on the domain_kernel_load_modules boolean. Disabled by
121 default.
122 setsebool -P domain_kernel_load_modules 1
124 If you want to allow all domains to execute in fips_mode, you must turn
128 on the fips_mode boolean. Enabled by default.
129 setsebool -P fips_mode 1
131 If you want to enable reading of urandom for all domains, you must turn
135 on the global_ssp boolean. Disabled by default.
136 setsebool -P global_ssp 1

142 The SELinux process type netlabel_mgmt_t can manage files labeled with
143 the following file types. The paths listed are the default paths for
144 these file types. Note the processes UID still need to have DAC per‐
145 missions.

184 SELinux requires files to have an extended attribute to define the file
185 type.
186 You can see the context of a file using the -Z option to ls
188 Policy governs the access confined processes have to these files.
190 SELinux netlabel_mgmt policy is very flexible allowing users to setup
191 their netlabel_mgmt processes in as secure a method as possible.
192 STANDARD FILE CONTEXT
194 SELinux defines the file context types for the netlabel_mgmt, if you
196 wanted to store files with these types in a diffent paths, you need to
197 execute the semanage command to sepecify alternate labeling and then
198 use restorecon to put the labels on disk.
199 semanage fcontext -a -t netlabel_mgmt_unit_file_t '/srv/mynetla‐
201 bel_mgmt_content(/.*)?'
202 restorecon -R -v /srv/mynetlabel_mgmt_content
203 Note: SELinux often uses regular expressions to specify labels that
205 match multiple files.
206 The following file types are defined for netlabel_mgmt:
208 netlabel_mgmt_exec_t
212 - Set files with the netlabel_mgmt_exec_t type, if you want to transi‐
214 tion an executable to the netlabel_mgmt_t domain.
215 Paths:
218 /sbin/netlabelctl, /usr/sbin/netlabelctl, /usr/sbin/netlabel-con‐
219 fig
220 netlabel_mgmt_unit_file_t
223 - Set files with the netlabel_mgmt_unit_file_t type, if you want to
225 treat the files as netlabel mgmt unit content.
226 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
236 semanage fcontext can also be used to manipulate default file context
237 mappings.
238 semanage permissive can also be used to manipulate whether or not a
240 process type is permissive.
241 semanage module can also be used to enable/disable/install/remove pol‐
243 icy modules.
244 semanage boolean can also be used to manipulate the booleans
246 system-config-selinux is a GUI tool available to customize SELinux pol‐
249 icy settings.
