--- Comment #2 from Conrad Meyer <[email protected]> ---
I believe this is due to copyinstr(), which works with NUL-terminated strings
(and lengths), while the stack buffer in sys_extattr_set_fd(), etc, are only
sized to EXTATTR_MAXNAMELEN.  To fix this I think we just need to size the
buffers one larger to allow for the trailing NUL copyinstr expects.
