6 cgdcbxd_selinux - Security Enhanced Linux Policy for the cgdcbxd pro‐
7 cesses
8
10 Security-Enhanced Linux secures the cgdcbxd processes via flexible
11 mandatory access control.
12 The cgdcbxd processes execute with the cgdcbxd_t SELinux type. You can
14 check if you have these processes running by executing the ps command
15 with the -Z qualifier.
16 For example:
18 ps -eZ | grep cgdcbxd_t
20
24 The cgdcbxd_t SELinux type can be entered via the cgdcbxd_exec_t file
25 type.
26 The default entrypoint paths for the cgdcbxd_t domain are the follow‐
28 ing:
29 /usr/sbin/cgdcbxd
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 cgdcbxd policy is very flexible allowing users to setup their cgdcbxd
40 processes in as secure a method as possible.
41 The following process types are defined for cgdcbxd:
43 cgdcbxd_t
45 Note: semanage permissive -a cgdcbxd_t can be used to make the process
47 type cgdcbxd_t permissive. SELinux does not deny access to permissive
48 process types, but the AVC (SELinux denials) messages are still gener‐
49 ated.
50
53 SELinux policy is customizable based on least access required. cgdcbxd
54 policy is extremely flexible and has several booleans that allow you to
55 manipulate the policy and run cgdcbxd with the tightest access possi‐
56 ble.

93 If you want to allow any process to mmap any file on system with

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 cgdcbxd_t can manage files labeled with the
143 following file types. The paths listed are the default paths for these
144 file types. Note the processes UID still need to have DAC permissions.

191 SELinux requires files to have an extended attribute to define the file
192 type.
193 You can see the context of a file using the -Z option to ls
195 Policy governs the access confined processes have to these files.
197 SELinux cgdcbxd policy is very flexible allowing users to setup their
198 cgdcbxd processes in as secure a method as possible.
199 STANDARD FILE CONTEXT
201 SELinux defines the file context types for the cgdcbxd, if you wanted
203 to store files with these types in a diffent paths, you need to execute
204 the semanage command to sepecify alternate labeling and then use
205 restorecon to put the labels on disk.
206 semanage fcontext -a -t cgdcbxd_var_run_t '/srv/mycgdcbxd_con‐
208 tent(/.*)?'
209 restorecon -R -v /srv/mycgdcbxd_content
210 Note: SELinux often uses regular expressions to specify labels that
212 match multiple files.
213 The following file types are defined for cgdcbxd:
215 cgdcbxd_exec_t
219 - Set files with the cgdcbxd_exec_t type, if you want to transition an
221 executable to the cgdcbxd_t domain.
222 cgdcbxd_unit_file_t
226 - Set files with the cgdcbxd_unit_file_t type, if you want to treat the
228 files as cgdcbxd unit content.
229 cgdcbxd_var_run_t
233 - Set files with the cgdcbxd_var_run_t type, if you want to store the
235 cgdcbxd files under the /run or /var/run directory.
236 Note: File context can be temporarily modified with the chcon command.
240 If you want to permanently change the file context you need to use the
241 semanage fcontext command. This will modify the SELinux labeling data‐
242 base. You will need to use restorecon to apply the labels.
243
246 semanage fcontext can also be used to manipulate default file context
247 mappings.
248 semanage permissive can also be used to manipulate whether or not a
250 process type is permissive.
251 semanage module can also be used to enable/disable/install/remove pol‐
253 icy modules.
254 semanage boolean can also be used to manipulate the booleans
256 system-config-selinux is a GUI tool available to customize SELinux pol‐
259 icy settings.
