Linux-mint wrong file-attributes over Samba-shares

[Rob van Snippenburg]

1. Situation :

- home network with 2 computers :
  - name : Googol-5; ip-address : 192.168.178.36 (fixed)
  - name : Googol-6; ip-address : 192.168.178.34 (fixed)
- both Linux mint 18.2 Sonya with Mate-desktop
- Linux Kernel : 4.10.0.38 (important part!)

2. Get Samba working : (no problems here. Just FYI)

- menu > administration > software manager : search for "samba"
  - install System-config-samba
  - install Samba
- configure samba :
  - sudo touch /etc/libuser.conf
  - menu > samba (samba server configuration)
  - preferences > server settings : workgroup : "workgroup"
  - add a samba share ("+" sign) : directory : "/home/rob"; share name : "dd"; writable; visible; access : allow access to everyone
- add 1 line in the [dd] section (bottom of the file) in /etc/samba/smb.conf : "force user = rob"
- sudo service nmbd (re)start
- sudo service smbd (re)start
- adjust firewall setting :
  - menu > preferences > firewall configuration :
  - rules > add :
    Policy : allow (or limit); Direction : In; Category : Network; Subcategory : File Transfer; Application : Samba <add>
- Create mount-point folders ;
  - sudo mkdir /media/rob/Googol-6
- Create file for lunux credentials :
  - sudo touch /etc/linux_credentials
  - sudo chmod 000 /etc/linux_credentials
  - sudo xed /etc/linux_credentials
    "
username=rob
password=...
domain=workgroup
    "
- add lines in /etc/fstab at the bottom :
  - sudo xed /etc/fstab (add at the bottom of the file)
    "
//192.168.178.34/dd /media/rob/Googol-6 cifs credentials=/etc/linux_credentials,noperm 0 0
#
    "
- sudo mount -a (or reboot the system)

3. Result in terminal (correct !!) :

rob@Googol-5 ~ $ ls -la /media/rob/Googol-6
total 26728

4. Updating to later version of Linux-kernel ( 4.13.0.31 ) (any 4.13.. will reproduce this error) :

5. Result in terminal (fault !!) : Group, Owner and Permissions are NOT correct:

rob@Googol-5 ~ $

6. reproducable :
   - Downgrading to linux Kernel 4.10.0.38 solves the problem
