Smack: adds smackfs/ptrace interface
This allows to limit ptrace beyond the regular smack access rules. It adds a smackfs/ptrace interface that allows smack to be configured to require equal smack labels for PTRACE_MODE_ATTACH access. See the changes in Documentation/security/Smack.txt below for details. Signed-off-by: Lukasz Pawelczyk <l.pawelczyk@partner.samsung.com> Signed-off-by: Rafal Krypa <r.krypa@samsung.com>
