To my understanding, you can lseek to any "proper" offset inside a directory. Proper means that the offset marks the beginning of a new dirent (or end of file) in the interpretation of the filesystem. A filesystem could use offset n for directory entry n, or it could interpret n as the offset in bytes and require that a dirent start at this offset (else the offset wouldn't be proper) or it could be anything else as well. Userspace doesn't have any means to figure out, which addresses are proper and which aren't. Except that getdents(2) moves the fd offset to a proper address, which likely will remain proper until the fd is closed. Reopening the same directory may result in a formerly proper offset isn't anymore. Does the above make sense?
