## `filepath-securejoin` ##
[![Build Status](https://travis-ci.org/cyphar/filepath-securejoin.svg?branch=master)](https://travis-ci.org/cyphar/filepath-securejoin)
An implementation of `SecureJoin`, a [candidate for inclusion in the Go
standard library][go#20126]. The purpose of this function is to be a "secure"
alternative to `filepath.Join`, and in particular it provides certain
guarantees that are not provided by `filepath.Join`.
This is the function prototype:
```go
func SecureJoin(root, unsafePath string) (string, error)
```
This library **guarantees** the following:
* If no error is set, the resulting string **must** be a child path of
`SecureJoin` and will not contain any symlink path components (they will all
be expanded).
* When expanding symlinks, all symlink path components **must** be resolved
relative to the provided root. In particular, this can be considered a
userspace implementation of how `chroot(2)` operates on file paths. Note that
these symlinks will **not** be expanded lexically (`filepath.Clean` is not
called on the input before processing).
* Non-existant path components are unaffected by `SecureJoin` (similar to
`filepath.EvalSymlinks`'s semantics).
* The returned path will always be `filepath.Clean`ed and thus not contain any
`..` components.
A (trivial) implementation of this function on GNU/Linux systems could be done
with the following (note that this requires root privileges and is far more
opaque than the implementation in this library, and also requires that
`readlink` is inside the `root` path):
```go
package securejoin
import (
"os/exec"
"path/filepath"
)
func SecureJoin(root, unsafePath string) (string, error) {
unsafePath = string(filepath.Separator) + unsafePath
cmd := exec.Command("chroot", root,
"readlink", "--canonicalize-missing", "--no-newline", unsafePath)
output, err := cmd.CombinedOutput()
if err != nil {
return "", err
}
expanded := string(output)
return filepath.Join(root, expanded), nil
}
```
