[Samba] fruit:resource=stream on ZFS safety?

[Chad William Seys]

Hi Mike and all,
    I still see ._ files with fruit:resource=xattr and not with 
fruit:resource=stream.
    Try extracting the attached zip file using a macintosh on the samba 
share. (Sounds dangerous, right?!)

    With fruit:resource=xattr
# ls -al
total 537
drwxrwx---+ 2 cwseys cwseys      9 Feb 17 09:57  .
drwxrwx---+ 3 cwseys cwseys      5 Feb 17 09:57  ..
-rwxrwxr--+ 1 cwseys cwseys  20120 Feb 17 09:57 'directory listing.png'
-rwxrwxr--+ 1 cwseys cwseys   6148 Feb 17 09:57  .DS_Store
-rwxrwxr--+ 1 cwseys cwseys  61808 Feb 17 09:57 '._RF=151KB Extension'
-rwxrwxr--+ 1 cwseys cwseys 543239 Feb 17 09:57 'RF=151KB Extension'
-rwxrwxr--+ 1 cwseys cwseys   4488 Feb 17 09:57 '._RF=4KB ReadMe'
-rwxrwxr--+ 1 cwseys cwseys   3519 Feb 17 09:57 'RF=4KB ReadMe'
-rwxrwxr--+ 1 cwseys cwseys 174806 Feb 17 09:57 'what the readme should 
look like.png'

    With fruit:resource=stream the directory looks the same as if it had 
been extracted on Macintosh local filesystem.  (The readme does not 
display as shown by 'what the readme should look like.png' when opened 
from either samba share or local Macintosh file system, so ignore that?)

# ls -al resourceForkTest/

-rwxrwxr--+ 1 cwseys cwseys 174806 Feb 17 10:13 'what the readme should

Some debug info:
Samba 4.9.18, zfs 0.8.3
# zfs get xattr tank/home_cwseys
NAME              PROPERTY  VALUE  SOURCE
tank/home_cwseys  xattr     sa     local

Relevant smb.conf

# global
fruit:nfs_aces = no

[share]
    inherit acls = Yes
    inherit permissions = Yes
    path = /srv/smb
    vfs objects = full_audit catia fruit streams_xattr
    fruit:veto_appledouble = no
    fruit:resource = stream
    fruit:metadata = stream
    fruit:encoding = native


Let me know your thoughts b/c I'd rather not use something marked 
'experimental' !

Thanks!
Chad.
