rgmanager_selinux(8) - Linux man page

Name

rgmanager_selinux - Security Enhanced Linux Policy for the rgmanager processes

Description

Security-Enhanced Linux secures the rgmanager processes via flexible mandatory access control.

The rgmanager processes execute with the rgmanager_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 rgmanager_t

Entrypoints

The rgmanager_t SELinux type can be entered via the "mtrr_device_t,unlabeled_t,proc_type,rgmanager_exec_t,sysctl_type,filesystem_type,file_type" file types. The default entrypoint paths for the rgmanager_t domain are the following:"

/dev/cpu/mtrr, /usr/lib(64)?/heartbeat/heartbeat, /usr/sbin/ccs_tool, /usr/sbin/cpglockd, /usr/sbin/cman_tool, /usr/sbin/rgmanager, all files on the system

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 rgmanager policy is very flexible allowing users to setup their rgmanager processes in as secure a method as possible.

The following process types are defined for rgmanager:

rgmanager_t

Note: semanage permissive -a rgmanager_t

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

Booleans

SELinux policy is customizable based on least access required. rgmanager policy is extremely flexible and has several booleans that allow you to manipulate the policy and run rgmanager with the tightest access possible.

If you want to allow rgmanager domain to connect to the network using TCP, you must turn on the rgmanager_can_network_connect boolean.

setsebool -P rgmanager_can_network_connect 1

If you want to allow rgmanager domain to connect to the network using TCP, you must turn on the rgmanager_can_network_connect boolean.

setsebool -P rgmanager_can_network_connect 1

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 rgmanager policy is very flexible allowing users to setup their rgmanager processes in as secure a method as possible.

The following file types are defined for rgmanager:

rgmanager_exec_t

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

rgmanager_initrc_exec_t

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

rgmanager_tmp_t

- Set files with the rgmanager_tmp_t type, if you want to store rgmanager temporary files in the /tmp directories.

rgmanager_tmpfs_t

- Set files with the rgmanager_tmpfs_t type, if you want to store rgmanager files on a tmpfs file system.

rgmanager_var_lib_t

- Set files with the rgmanager_var_lib_t type, if you want to store the rgmanager files under the /var/lib directory.

rgmanager_var_log_t

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

rgmanager_var_run_t

- Set files with the rgmanager_var_run_t type, if you want to store the rgmanager 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 rgmanager_t can manage files labeled with the following file types. The paths listed are the default paths for these file types. Note the processes UID still need to have DAC permissions.

file_type

all files on the system

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 policy modules.

semanage boolean can also be used to manipulate the booleans

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