NAME

uml_selinux - Security Enhanced Linux Policy for the uml processes

DESCRIPTION

SELinux Linux secures uml (Policy for UML) processes via flexible mandatory access control.

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

The following file types are defined for uml:

uml_exec_t

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

uml_ro_t

- Set files with the uml_ro_t type, if you want to treat the files as uml read/only content.

uml_rw_t

- Set files with the uml_rw_t type, if you want to treat the files as uml read/write content.

uml_switch_exec_t

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

uml_switch_var_run_t

- Set files with the uml_switch_var_run_t type, if you want to store the uml switch files under the /run directory.

uml_tmp_t

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

uml_tmpfs_t

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

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.

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

The following process types are defined for uml:

uml_switch_t, uml_t

Note: semanage permissive -a PROCESS_TYPE can be used to make a process type permissive. Permissive process types are not denied access by SELinux. AVC messages will still be generated.

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.

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