Types

type ReverseFS

type ReverseFS struct {
	// Embed pathfs.defaultFileSystem for a ENOSYS implementation of all methods
	pathfs.FileSystem
	// contains filtered or unexported fields
}

ReverseFS implements the pathfs.FileSystem interface and provides an encrypted view of a plaintext directory.

func NewFS

func NewFS(args fusefrontend.Args, c *contentenc.ContentEnc, n *nametransform.NameTransform) *ReverseFS

NewFS returns an encrypted FUSE overlay filesystem. In this case (reverse mode) the backing directory is plain-text and ReverseFS provides an encrypted view.

func (*ReverseFS) Access

func (rfs *ReverseFS) Access(relPath string, mode uint32, context *fuse.Context) fuse.Status

Access - FUSE call

func (*ReverseFS) DecryptPath

func (rfs *ReverseFS) DecryptPath(cipherPath string) (string, error)

DecryptPath implements ctlsock.Backend

func (*ReverseFS) EncryptPath

func (rfs *ReverseFS) EncryptPath(plainPath string) (string, error)

EncryptPath implements ctlsock.Backend. This is actually not used inside reverse mode, but we implement it because third-party tools want to encrypt paths through the control socket.

func (*ReverseFS) GetAttr

func (rfs *ReverseFS) GetAttr(relPath string, context *fuse.Context) (*fuse.Attr, fuse.Status)

GetAttr - FUSE call "relPath" is the relative ciphertext path

func (*ReverseFS) Open

func (rfs *ReverseFS) Open(relPath string, flags uint32, context *fuse.Context) (fuseFile nodefs.File, status fuse.Status)

Open - FUSE call

func (*ReverseFS) OpenDir

func (rfs *ReverseFS) OpenDir(cipherPath string, context *fuse.Context) ([]fuse.DirEntry, fuse.Status)

OpenDir - FUSE readdir call

func (*ReverseFS) Readlink

func (rfs *ReverseFS) Readlink(relPath string, context *fuse.Context) (string, fuse.Status)

Readlink - FUSE call

func (*ReverseFS) StatFs

func (rfs *ReverseFS) StatFs(path string) *fuse.StatfsOut

StatFs - FUSE call. Returns information about the filesystem (free space etc). Securing statfs against symlink races seems to be more trouble than it's worth, so we just ignore the path and always return info about the backing storage root dir.
