6 cgclear_selinux - Security Enhanced Linux Policy for the cgclear pro‐
7 cesses
8
10 Security-Enhanced Linux secures the cgclear processes via flexible
11 mandatory access control.
12 The cgclear processes execute with the cgclear_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 cgclear_t
20
24 The cgclear_t SELinux type can be entered via the cgclear_exec_t file
25 type.
26 The default entrypoint paths for the cgclear_t domain are the follow‐
28 ing:
29 /sbin/cgclear, /usr/sbin/cgclear
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 cgclear policy is very flexible allowing users to setup their cgclear
40 processes in as secure a method as possible.
41 The following process types are defined for cgclear:
43 cgclear_t
45 Note: semanage permissive -a cgclear_t can be used to make the process
47 type cgclear_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. cgclear
54 policy is extremely flexible and has several booleans that allow you to
55 manipulate the policy and run cgclear with the tightest access possi‐
56 ble.
57 If you want to allow users to resolve user passwd entries directly from
61 ldap rather then using a sssd server, you must turn on the authlo‐
62 gin_nsswitch_use_ldap boolean. Disabled by default.

93 If you want to deny any process from ptracing or debugging any other
97 processes, you must turn on the deny_ptrace boolean. Enabled by
98 default.

101 If you want to allow any process to mmap any file on system with
105 attribute file_type, you must turn on the domain_can_mmap_files bool‐
106 ean. Enabled by default.
107 setsebool -P domain_can_mmap_files 1
109 If you want to allow all domains write to kmsg_device, while kernel is
113 executed with systemd.log_target=kmsg parameter, you must turn on the
114 domain_can_write_kmsg boolean. Disabled by default.
115 setsebool -P domain_can_write_kmsg 1
117 If you want to allow all domains to use other domains file descriptors,
121 you must turn on the domain_fd_use boolean. Enabled by default.
122 setsebool -P domain_fd_use 1
124 If you want to allow all domains to have the kernel load modules, you
128 must turn on the domain_kernel_load_modules boolean. Disabled by
129 default.
130 setsebool -P domain_kernel_load_modules 1
132 If you want to allow all domains to execute in fips_mode, you must turn
136 on the fips_mode boolean. Enabled by default.
137 setsebool -P fips_mode 1
139 If you want to enable reading of urandom for all domains, you must turn
143 on the global_ssp boolean. Disabled by default.
144 setsebool -P global_ssp 1
146 If you want to allow confined applications to run with kerberos, you
150 must turn on the kerberos_enabled boolean. Enabled by default.
151 setsebool -P kerberos_enabled 1
153 If you want to allow system to run with NIS, you must turn on the
157 nis_enabled boolean. Disabled by default.
158 setsebool -P nis_enabled 1
160 If you want to allow confined applications to use nscd shared memory,
164 you must turn on the nscd_use_shm boolean. Disabled by default.
165 setsebool -P nscd_use_shm 1

171 The SELinux process type cgclear_t can manage files labeled with the
172 following file types. The paths listed are the default paths for these
173 file types. Note the processes UID still need to have DAC permissions.
174 cgroup_t
176 /sys/fs/cgroup
178 cluster_conf_t
180 /etc/cluster(/.*)?
182 cluster_var_lib_t

216 SELinux requires files to have an extended attribute to define the file
217 type.
218 You can see the context of a file using the -Z option to ls
220 Policy governs the access confined processes have to these files.
222 SELinux cgclear policy is very flexible allowing users to setup their
223 cgclear processes in as secure a method as possible.
224 The following file types are defined for cgclear:
226 cgclear_exec_t
230 - Set files with the cgclear_exec_t type, if you want to transition an
232 executable to the cgclear_t domain.
233 Paths:
236 /sbin/cgclear, /usr/sbin/cgclear
237 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.
