xend_selinux(8) xend SELinux Policy documentation xend_selinux(8)NAMExend_selinux - Security Enhanced Linux Policy for the xend processes
DESCRIPTION
Security-Enhanced Linux secures the xend processes via flexible manda‐
tory access control.
BOOLEANS
SELinux policy is customizable based on least access required. xend
policy is extremely flexible and has several booleans that allow you to
manipulate the policy and run xend with the tightest access possible.
If you want to allow xen to manage nfs file, you must turn on the
xen_use_nfs boolean.
setsebool -P xen_use_nfs 1
If you want to allow xend to run qemu-dm. Not required if using par‐
avirt and no vfb, you must turn on the xend_run_qemu boolean.
setsebool -P xend_run_qemu 1
If you want to allow xend to run blktapctrl/tapdisk. Not required if
using dedicated logical volumes for disk images, you must turn on the
xend_run_blktap boolean.
setsebool -P xend_run_blktap 1
NSSWITCH DOMAINFILE 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 xend policy is very flexible allowing users to setup their xend
processes in as secure a method as possible.
The following file types are defined for xend:
xend_exec_t
- Set files with the xend_exec_t type, if you want to transition an
executable to the xend_t domain.
xend_tmp_t
- Set files with the xend_tmp_t type, if you want to store xend tempo‐
rary files in the /tmp directories.
xend_var_lib_t
- Set files with the xend_var_lib_t type, if you want to store the xend
files under the /var/lib directory.
Paths:
/var/lib/xen(/.*)?, /var/lib/xend(/.*)?
xend_var_log_t
- Set files with the xend_var_log_t type, if you want to treat the data
as xend var log data, usually stored under the /var/log directory.
Paths:
/var/log/xen(/.*)?, /var/log/xen-hotplug.log, /var/log/xend.log,
/var/log/xend-debug.log
xend_var_run_t
- Set files with the xend_var_run_t type, if you want to store the xend
files under the /run directory.
Paths:
/var/run/xenner(/.*)?, /var/run/xend(/.*)?, /var/run/xend.pid
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.
PORT TYPES
SELinux defines port types to represent TCP and UDP ports.
You can see the types associated with a port by using the following
command:
semanage port -l
Policy governs the access confined processes have to these ports.
SELinux xend policy is very flexible allowing users to setup their xend
processes in as secure a method as possible.
The following port types are defined for xend:
xen_port_t
Default Defined Ports:
tcp 8002
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
xend policy is very flexible allowing users to setup their xend pro‐
cesses in as secure a method as possible.
The following process types are defined for xend:
xend_t, xenstored_t, xenconsoled_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.
semanage port can also be used to manipulate the port definitions
semanage boolean can also be used to manipulate the booleans
system-config-selinux is a GUI tool available to customize SELinux pol‐
icy settings.
