How to mount iso file with selinux context












0















I am trying to mount iso file in /var/ftp/pub/centos



When I try to access those files using ftp in web browser it's not working . After troubleshooting I found that it's because of selinux.




dr-xr-xr-x. root root system_u:object_r:iso9660_t:s0 centos
-rw-r--r--. root root unconfined_u:object_r:public_content_t:s0 CentOS-6.10-x86_64-bin-DVD1.iso



Is it possible to mount iso including selinux ?



I referred this method (used selinux context for ftp) but it didn't work for me.



OS I am using CentOS release 6.10.

          I also could not get this working. As the "semanage fcontext" + restorecon won't also work because of the FS being read-only, I would merely add an exception to allow httpd reading those files (I think this brings no significant security issue):





          • set permissive mode to make sure all relevants denials appear in audit.log



            $ sudo setenforce permissive



          • mount the ISO and read files through the WEB server.



          • denial messages should be found by:



            $ sudo grep denied /var/log/audit/audit.log | grep httpd | grep iso9660_t




          • build a selinux exception module with these denial events and apply it



            $ sudo grep denied /var/log/audit/audit.log | grep httpd | grep iso9660_t | audit2allow -M my-iso-rules
            $ sudo semodule -i my-iso-rules.pp




          • restore enforcing mode:



            $ sudo setenforce enforcing
