Functions

func BindFdToPath

func BindFdToPath(fd uintptr, targetPath string) error

BindFdToPath creates a bind mount from the open file (which is actually a directory) to the specified location. If it succeeds, the caller will need to unmount the targetPath when it's finished using it. Regardless, it closes the passed-in descriptor.

func InChroot

func InChroot(root, wd, path string, mode int, perm uint32) (fd int, errno syscall.Errno, err error)

InChroot opens the file at `path` after chrooting to `root` and then changing its working directory to `wd`. Both `wd` and `path` are evaluated in the chroot. Returns a file handle, an Errno value if there was an error and the underlying error was a standard library error code, and a non-empty error if one was detected.
