lvm_selinux(8) lvm SELinux Policy documentation lvm_selinux(8)NAMElvm_selinux - Security Enhanced Linux Policy for the lvm processes
DESCRIPTION
Security-Enhanced Linux secures the lvm processes via flexible manda‐
tory access control.
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 lvm policy is very flexible allowing users to setup their lvm
processes in as secure a method as possible.
The following file types are defined for lvm:
lvm_etc_t
- Set files with the lvm_etc_t type, if you want to store lvm files in
the /etc directories.
lvm_exec_t
- Set files with the lvm_exec_t type, if you want to transition an exe‐
cutable to the lvm_t domain.

lvm_lock_t
- Set files with the lvm_lock_t type, if you want to treat the files as
lvm lock data, stored under the /var/lock directory
Paths:
/var/lock/lvm(/.*)?, /etc/lvm/lock(/.*)?
lvm_metadata_t
- Set files with the lvm_metadata_t type, if you want to treat the
files as lvm metadata data.
Paths:
/etc/lvm/backup(/.*)?, /var/cache/multipathd(/.*)?,
/etc/lvmtab.d(/.*)?, /etc/lvmtab(/.*)?, /etc/lvm/.cache,
/etc/lvm/archive(/.*)?, /etc/lvm/cache(/.*)?
lvm_tmp_t
- Set files with the lvm_tmp_t type, if you want to store lvm temporary
files in the /tmp directories.
lvm_var_lib_t
- Set files with the lvm_var_lib_t type, if you want to store the lvm
files under the /var/lib directory.
lvm_var_run_t
- Set files with the lvm_var_run_t type, if you want to store the lvm
files under the /run directory.
Paths:
/var/run/lvm(/.*)?, /var/run/multipathd.sock, /var/run/dmevent.*
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
lvm policy is very flexible allowing users to setup their lvm processes
in as secure a method as possible.
The following process types are defined for lvm:
lvm_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.
