This the backport of #3956 to
release-1.1
, the original description is:Fix #3952
When we call
unix.Mount
, if we use file mode bits from the bits with the typefs.FileMode
directly, it will cause some bits missing.Please refer: https://github.com/golang/go/blob/master/src/os/file.go#L258-L265
