RELENG_6 weird '..' permission troubles

[Dmitry Morozovsky]

Dear colleagues,

I have misterious permission troubles on rather fresh RELENG_6:

from root everything's ok:

root at hasmter:/usr# ls -la /usr/
total 48
drwxr-xr-x  13 root  wheel      512 Feb  2 20:59 ./
drwxr-xr-x  20 root  wheel      512 Feb 16 14:37 ../
drwxrwx---   2 root  operator   512 Feb 16 15:58 .snap/
drwxr-xr-x   3 root  wheel      512 Feb  2 16:08 X11R6/
...

from myself too:

marck at hasmter:~> ls -la /usr/
total 48
drwxr-xr-x  13 root  wheel      512 Feb  2 20:59 ./
drwxr-xr-x  20 root  wheel      512 Feb 16 14:37 ../
drwxrwx---   2 root  operator   512 Feb 16 15:58 .snap/
drwxr-xr-x   3 root  wheel      512 Feb  2 16:08 X11R6/
...
marck at hasmter:~> id
uid=268(marck) gid=268(marck) groups=268(marck), 0(wheel), 5(operator)

but from really unprivileged user:

%id
uid=1008(nata) gid=1008(nata) groups=1008(nata), 24(samba)
%ls -la /usr
ls: ..: Permission denied
total 46
drwxr-xr-x  13 root  wheel      512 Feb  2 20:59 .
drwxrwx---   2 root  operator   512 Feb 16 15:58 .snap
drwxr-xr-x   3 root  wheel      512 Feb  2 16:08 X11R6
...

The same on other mountpoints. fsck is ok. 

Any hints? 


Sincerely,
D.Marck                                     [DM5020, MCK-RIPE, DM3-RIPN]
