cgred_selinux(8) SELinux Policy documentation for cgred cgred_selinux(8)

NAME cgred_selinux - Security Enhanced Linux Policy for the cgred processes

DESCRIPTION Security-Enhanced Linux secures the cgred processes via flexible manda- tory access control.

The cgred processes execute with the cgred_t SELinux type. You can check if you have these processes running by executing the ps command with the -Z qualifier.

For example:

ps -eZ | grep cgred_t

ENTRYPOINTS The cgred_t SELinux type can be entered via the "cgred_exec_t" file type. The default entrypoint paths for the cgred_t domain are the fol- lowing:"

/sbin/cgrulesengd

PROCESS TYPES SELinux defines process types (domains) for each process running on the system

You can see the context of a process using the -Z option to ps

Policy governs the access confined processes have to files. SELinux cgred policy is very flexible allowing users to setup their cgred pro- cesses in as secure a method as possible.

The following process types are defined for cgred:

cgred_t

Note: semanage permissive -a cgred_t

can be used to make the process type cgred_t permissive. Permissive process types are not denied access by SELinux. AVC messages will still be generated.

FILE CONTEXTS SELinux requires files to have an extended attribute to define the file type.

You can see the context of a file using the -Z option to ls

Policy governs the access confined processes have to these files. SELinux cgred policy is very flexible allowing users to setup their cgred processes in as secure a method as possible.

The following file types are defined for cgred:

cgred_exec_t

- Set files with the cgred_exec_t type, if you want to transition an executable to the cgred_t domain.

cgred_initrc_exec_t

- Set files with the cgred_initrc_exec_t type, if you want to transi- tion an executable to the cgred_initrc_t domain.

cgred_log_t

- Set files with the cgred_log_t type, if you want to treat the data as cgred log data, usually stored under the /var/log directory.

cgred_var_run_t

- Set files with the cgred_var_run_t type, if you want to store the cgred files under the /run directory.

Note: File context can be temporarily modified with the chcon command. If you want to permanently change the file context you need to use the semanage fcontext command. This will modify the SELinux labeling database. You will need to use restorecon to apply the labels.

MANAGED FILES The SELinux process type cgred_t can manage files labeled with the fol- lowing file types. The paths listed are the default paths for these file types. Note the processes UID still need to have DAC permissions.

cgred_log_t

/var/log/cgrulesengd.log.*

cgred_var_run_t

/var/run/cgred.*

cgroup_t

/cgroup(/.*)?

initrc_tmp_t

mnt_t

/mnt(/[^/]*) /mnt(/[^/]*)? /rhev(/[^/]*)? /media(/[^/]*) /media(/[^/]*)? /etc/rhgb(/.*)? /media/.hal-.* /net /afs /misc /rhev

root_t

/ /initrd

tmp_t

/tmp /usr/tmp /var/tmp /var/tmp/vi.recover

COMMANDS semanage fcontext can also be used to manipulate default file context mappings.

semanage permissive can also be used to manipulate whether or not a process type is permissive.

semanage module can also be used to enable/disable/install/remove pol- icy modules.

system-config-selinux is a GUI tool available to customize SELinux pol- icy settings.
