NAME

lvm_selinux - Security Enhanced Linux Policy for the lvm processes

DESCRIPTION

SELinux Linux secures lvm (Policy for logical volume management programs) 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 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 executable to the lvm_t domain.

Paths:: /sbin/dmraid, /sbin/pvremove, /sbin/vgextend, /lib/lvm-200/.*, /sbin/vgmerge, /sbin/vgrename, /sbin/lvdisplay, /sbin/pvs, /sbin/lvmdiskscan, /sbin/lvresize, /sbin/vgmknodes, /sbin/pvmove, /sbin/multipath.static, /sbin/vgck, /sbin/pvscan, /sbin/pvcreate, /sbin/lvreduce, /sbin/vgscan, /sbin/lvremove, /sbin/dmsetup, /usr/sbin/lvm, /sbin/vgchange, /sbin/lvm.static, /sbin/vgcfgbackup, /sbin/e2fsadm, /sbin/lvm, /sbin/pvdata, /sbin/lvextend, /sbin/vgcfgrestore, /sbin/vgs, /sbin/lvmchange, /sbin/vgimport, /sbin/vgremove, /sbin/dmsetup.static, /sbin/lvmsar, /sbin/lvmsadc, /sbin/lvmiopversion, /sbin/pvchange, /sbin/pvdisplay, /sbin/vgsplit, /sbin/multipathd, /sbin/cryptsetup, /sbin/vgwrapper, /sbin/lvchange, /sbin/mount.crypt, /sbin/vgcreate, /sbin/vgreduce, /sbin/lvrename, /sbin/vgscan.static, /sbin/vgexport, /sbin/lvs, /sbin/vgchange.static, /sbin/kpartx, /lib/lvm-10/.*, /sbin/lvscan, /sbin/lvcreate, /sbin/vgdisplay, /lib/udev/udisks-lvm-pv-export

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/multipathd.sock, /var/run/dmevent.*

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 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 policy modules.

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