blktap_selinux(8)     blktap SELinux Policy documentation    blktap_selinux(8)

NAME
       blktap_selinux  -  Security  Enhanced  Linux Policy for the blktap pro‐
       cesses

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

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

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

       The following file types are defined for blktap:

       blktap_exec_t

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

       Paths:
	    /usr/sbin/blktapctrl, /usr/sbin/tapdisk

       blktap_var_run_t

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

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

       The following process types are defined for blktap:

       blktap_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 boolean can also be used to manipulate the booleans

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