Programs that do an IOCTL are bogus, but there's no harm in allowing it. As for getattr, that's valid so I've changed my tree to allow that too. Read was already allowed for SSP (which only does blind reads with no getattr and no ioctl). -- http://www.coker.com.au/selinux/ My NSA Security Enhanced Linux packages http://www.coker.com.au/bonnie++/ Bonnie++ hard drive benchmark http://www.coker.com.au/postal/ Postal SMTP/POP benchmark http://www.coker.com.au/~russell/ My home page
