xattr Crashing (Is This a Bug?)

[ewhac]

I copied a video file over a CIFS share from a Linux client to the (new) FreeNAS box (v11.1-U4). Upon inspecting it from a FreeNAS shell, it had acquired an xattr named DOSATTRIB (where did it come from?). When I tried to inspect it using xattr, it crashed:

Code:

[ewhac@freenas ~]$ ls -l

DOSATTRIB
[ewhac@freenas ~]$ xattr -p DOSATTRIB 2017-03-19\ 17-36-31.mkv

	print("".join((file_prefix, attr_value)))

	if attr_value.find('\0') >= 0:
TypeError: a bytes-like object is required, not 'str'

This feels like an incomplete port from Python 2.7 to 3.x.

This has been fixed in the Nightlies (which will become the next version).
