[patch] policy: add new permission setsuid to file class

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Add a new permission to the file class and a corresponding policy
capability.  This is checked any time chmod is called and the suid or
sgid bits are set or will be set on that file.  This does not enable the
permission in policy, only defines it.
