Description of problem:

SELinux denial when plugging in a USB Floppy drive

Version-Release number of selected component (if applicable):

Fedora 10 
selinux-policy-3.5.13-38.fc10.noarch
selinux-policy-targeted-3.5.13-38.fc10.noarch


How reproducible:
Always.

Steps to Reproduce:
1. Plug USB Floppy drive in
  
Actual results:

Unable to use Floppy drive (/dev/sdb because its USB).
Specifically, unable to use the floppy drive in VirtualBox due to a permission-denied error.

SELinux Denial:

node=foo.example.com type=AVC msg=audit(1231776458.106:22): avc:  denied  { getattr } for  pid=4489 comm="setfacl" path="/dev/sdb" dev=tmpfs ino=19716 scontext=system_u:system_r:hald_acl_t:s0 tcontext=system_u:object_r:fixed_disk_device_t:s0 tclass=blk_file

node=foo.example.com type=SYSCALL msg=audit(1231776458.106:22): arch=40000003 syscall=196 success=no exit=-13 a0=bfb97828 a1=bfb97758 a2=b98ff4 a3=1 items=0 ppid=4487 pid=4489 auid=4294967295 uid=0 gid=0 euid=0 suid=0 fsuid=0 egid=0 sgid=0 fsgid=0 tty=(none) ses=4294967295 comm="setfacl" exe="/usr/bin/setfacl" subj=system_u:system_r:hald_acl_t:s0 key=(null)



Expected results:

No Denial and able to use/mount floppy disks via USB floppy drive.


Additional info:

This problem persists regardless of whether I have a floppy disk (1.44MB) inserted when I plug the device in or not.

I tried running  restorecon -v '/dev/sdb'  as suggested - this appears to have no effect:

[root@foo ~]# ls -laZ /dev/sdb
brw-rw----  root disk system_u:object_r:fixed_disk_device_t:s0 /dev/sdb
[root@foo ~]# restorecon -v '/dev/sdb'
[root@foo ~]# ls -laZ /dev/sdb
brw-rw----  root disk system_u:object_r:fixed_disk_device_t:s0 /dev/sdb

I also tried following the instructions at http://fedora.redhat.com/docs/selinux-faq-fc5/#id2961385 (as listed in the AVC Denial message):

[root@foo ~]# audit2allow -m local -l -i /var/log/audit/audit.log > local.te
[root@foo ~]# cat local.te

module local 1.0;

require {
        type hald_acl_t;
        type fixed_disk_device_t;
        class blk_file getattr;
}

#============= hald_acl_t ==============
allow hald_acl_t fixed_disk_device_t:blk_file getattr;

[root@foo ~]# semodule -i local.te
