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
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 all daemons to write corefiles to /, you must turn
61 on the allow_daemons_dump_core boolean. Disabled by default.
62 setsebool -P allow_daemons_dump_core 1
64 If you want to allow all daemons to use tcp wrappers, you must turn on
68 the allow_daemons_use_tcp_wrapper boolean. Disabled by default.
69 setsebool -P allow_daemons_use_tcp_wrapper 1
71 If you want to allow all daemons the ability to read/write terminals,
75 you must turn on the allow_daemons_use_tty boolean. Disabled by
76 default.
77 setsebool -P allow_daemons_use_tty 1
79 If you want to allow all domains to use other domains file descriptors,
83 you must turn on the allow_domain_fd_use boolean. Enabled by default.
84 setsebool -P allow_domain_fd_use 1
86 If you want to allow sysadm to debug or ptrace all processes, you must
90 turn on the allow_ptrace boolean. Disabled by default.
91 setsebool -P allow_ptrace 1
93 If you want to enable cluster mode for daemons, you must turn on the
97 daemons_enable_cluster_mode boolean. Disabled by default.
98 setsebool -P daemons_enable_cluster_mode 1
100 If you want to allow all domains to have the kernel load modules, you
104 must turn on the domain_kernel_load_modules boolean. Disabled by
105 default.
106 setsebool -P domain_kernel_load_modules 1
108 If you want to allow all domains to execute in fips_mode, you must turn
112 on the fips_mode boolean. Enabled by default.
113 setsebool -P fips_mode 1
115 If you want to enable reading of urandom for all domains, you must turn
119 on the global_ssp boolean. Disabled by default.
120 setsebool -P global_ssp 1
122 If you want to enable support for upstart as the init program, you must
126 turn on the init_upstart boolean. Enabled by default.
127 setsebool -P init_upstart 1

133 The SELinux process type cgclear_t can manage files labeled with the
134 following file types. The paths listed are the default paths for these
135 file types. Note the processes UID still need to have DAC permissions.

200 SELinux requires files to have an extended attribute to define the file
201 type.
202 You can see the context of a file using the -Z option to ls
204 Policy governs the access confined processes have to these files.
206 SELinux cgclear policy is very flexible allowing users to setup their
207 cgclear processes in as secure a method as possible.
208 The following file types are defined for cgclear:
210 cgclear_exec_t
214 - Set files with the cgclear_exec_t type, if you want to transition an
216 executable to the cgclear_t domain.
217 Note: File context can be temporarily modified with the chcon command.
221 If you want to permanently change the file context you need to use the
222 semanage fcontext command. This will modify the SELinux labeling data‐
223 base. You will need to use restorecon to apply the labels.
224
227 semanage fcontext can also be used to manipulate default file context
228 mappings.
229 semanage permissive can also be used to manipulate whether or not a
231 process type is permissive.
232 semanage module can also be used to enable/disable/install/remove pol‐
234 icy modules.
235 semanage boolean can also be used to manipulate the booleans
237 system-config-selinux is a GUI tool available to customize SELinux pol‐
240 icy settings.
