Description of problem:
  dund isn't able to start a pppd conection over bluetooth.
  I get an error that he isn't able to open /dev/rfcomm0
  From the syslog:
    pppd[...]: Couldn't stat /dev/rfcomm0: Permission denied

Version-Release number of selected component (if applicable):
  bluez-utils-2.15-7
  selinux-policy-targeted-1.27.1-2.1

How reproducible:


Steps to Reproduce:
1. Configure bluetooth and dund as server
2. Use enforcement in selinux
3. Setup a "dund" connection
  
Actual results:
  You get the following error in syslog:
    pppd[...]: Couldn't stat /dev/rfcomm0: Permission denied

Expected results:
  ppp should start and you should be able to use ip on the other device


Additional info:
  The problem is the selinux permisions on "/dev/rfcomm0".
  The default permisions are:
    # ls -lZ /dev/rfcomm0
    crw-rw----  root root system_u:object_r:device_t     /dev/rfcomm0
  I have changed "/etc/selinux/targeted/contexts/files/file_contexts".
  I added the folling line (i copied the "/dev/ircomm" line):
    /dev/rfcomm[0-9]+       -c      system_u:object_r:tty_device_t
  That changes the permisions for "/dev/rfcomm0" to:
    # ls -lZ /dev/rfcomm0
    crw-rw----  root root system_u:object_r:tty_device_t /dev/rfcomm0
  With this setup it works.

  Ofcourse it also works when you disable selinux!
