uml_selinux(8) uml SELinux Policy documentation uml_selinux(8)
NAME
uml_selinux - Security Enhanced Linux Policy for the uml processes
DESCRIPTION
Security-Enhanced Linux secures the uml processes via flexible manda‐
tory access control.
NSSWITCH DOMAIN
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 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 exe‐
cutable 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 permanantly change the file context you need to use the
semanage fcontext command. This will modify the SELinux labeling data‐
base. 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 ps
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 pol‐
icy modules.
system-config-selinux is a GUI tool available to customize SELinux pol‐
icy settings.
