Hi, it looks that you rediscovered a bug ...

Craig Niederberger wrote:
Thanks for answering my post, Josef.  Unfortunately, I'm getting
exactly the same AVC denial and message when trying to access the
drive from vmware.  The odd thing is, I can access my home directory
from vmware without problem.  The /etc/fstab entry now reads:

/dev/sdd1 /mnt/media ntfs-3g
rw,locale=en_US.utf8,uid=500,gid=1000,context=system_u:system_r:samba_share_t
0 0

I've tried to a little bit investigate things,
in this case the forced context is completely ignored ...

[root@localhost vmware]# ls -Z /mnt/
drwxr-xr-x  root root system_u:object_r:mnt_t:s0       foo

[root@localhost vmware]# mount -t ntfs-3g -o loop,offset=32256,context=blabla ntfsImg-flat /mnt/foo/

[root@localhost vmware]# ls -Z /mnt/
drwxrwxrwx  root root system_u:object_r:fusefs_t:s0    foo

[root@localhost vmware]# umount /mnt/foo/

[root@localhost vmware]# mount -t ntfs-3g -o context=blabla:bleble:blabla,loop,offset=32256 ntfsImg-flat /mnt/foo/

[root@localhost vmware]# ls -Z /mnt/
drwxrwxrwx  root root system_u:object_r:fusefs_t:s0    foo

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

But not in this case.

[root@localhost vmware]# cat /dev/zero > file
[root@localhost vmware]# mkfs.ext3 file
...
[root@localhost vmware]# mount -o loop,context=system_u:object_r:httpd_sys_content_t:s0 file /mnt/foo/

[root@localhost vmware]# ls -Z /mnt/
drwxr-xr-x  root root system_u:object_r:httpd_sys_content_t:s0 foo

Similar bug(s) has been already reported.
https://bugzilla.redhat.com/show_bug.cgi?id=216846


Following command should help :-(

# setsebool -P samba_run_unconfined 1

Bye.
Josef
