Functions ¶
func IsIntegrityFS ¶
IsIntegrityFS checks if the fstype string contains an integrity suffix. If yes, returns the trimmed fstype and true, fstype and false otherwise.
Types ¶
type CryptDevice ¶
type CryptDevice struct {
*cryptsetup.Device
}
CryptDevice is a wrapper for cryptsetup.Device.
func (*CryptDevice) Free ¶
func (c *CryptDevice) Free() bool
Free releases crypt device context and used memory.
func (*CryptDevice) Init ¶
func (c *CryptDevice) Init(devicePath string) error
Init initializes a crypt device backed by 'devicePath'. Sets the cryptDevice's deviceMapper to the newly allocated Device or returns any error encountered.
func (*CryptDevice) InitByName ¶
func (c *CryptDevice) InitByName(name string) error
InitByName initializes a crypt device from provided active device 'name'. Sets the deviceMapper to the newly allocated Device or returns any error encountered.
type CryptMapper ¶
type CryptMapper struct {
// contains filtered or unexported fields
}
CryptMapper manages dm-crypt volumes.
func New ¶
func New(kms KeyCreator, mapper deviceMapper) *CryptMapper
New initializes a new CryptMapper with the given kms client and key-encryption-key ID. kms is used to fetch data encryption keys for the dm-crypt volumes.
func (*CryptMapper) CloseCryptDevice ¶
func (c *CryptMapper) CloseCryptDevice(volumeID string) error
CloseCryptDevice closes the crypt device mapped for volumeID. Returns nil if the volume does not exist.
func (*CryptMapper) GetDevicePath ¶
func (c *CryptMapper) GetDevicePath(volumeID string) (string, error)
GetDevicePath returns the device path of a mapped crypt device.
func (*CryptMapper) OpenCryptDevice ¶
func (c *CryptMapper) OpenCryptDevice(ctx context.Context, source, volumeID string, integrity bool) (string, error)
OpenCryptDevice maps the volume at source to the crypt device identified by volumeID. The key used to encrypt the volume is fetched using CryptMapper's kms client.
func (*CryptMapper) ResizeCryptDevice ¶
ResizeCryptDevice resizes the underlying crypt device and returns the mapped device path.
