Public bug reported:
I'm using 16.10. I have a DVD with strange permissions for the root
folder:
michele@cassandra:~$ ls -l /media/michele
total 2
d--x--x--- 3 michele michele 88 gen 1 2004 SONY_DVD_RECORDER_VOLUME
The DVD is readable e.g. on windows but with ubuntu while I can access
it as root:
root@cassandra:~# ls -l /media/michele/SONY_DVD_RECORDER_VOLUME/
total 4
dr-xr-xr-x 2 michele michele 3628 gen 1 2004 VIDEO_TS
I cannot as the non-root user that is logged in when I insert the disk:
michele@cassandra:~$ ls -l /media/michele/SONY_DVD_RECORDER_VOLUME
ls: cannot open directory '/media/michele/SONY_DVD_RECORDER_VOLUME': Permission
denied
Looking at the mount options it seems to me that this is a regression
for bug #10550. The options used by udisks2 are:
root@cassandra:~# mount |grep SONY
/dev/sr0 on /media/michele/SONY_DVD_RECORDER_VOLUME type udf
(ro,nosuid,nodev,relatime,uid=1000,gid=1000,iocharset=utf8,uhelper=udisks2)
while my understanding from bug #10550 is that I should have also
mode=0777 and dmode=0777
And indeed this works:
root@cassandra:~# mount -t udf -o
ro,nosuid,nodev,relatime,uid=1000,gid=1000,iocharset=utf8,uhelper=udisks2,mode=0777,dmode=0777
/dev/sr0 ~michele/z
michele@cassandra:~$ ls -l ~michele/z
total 4
drwxrwxrwx 2 michele michele 3628 gen 1 2004 VIDEO_TS
