Hi all, I am trying to check that a process (struct proc) has root powers when it calls my KLD system call. I know from kern_jail.c that I can use suser() but this function takes a struct thread* instead of struct proc* although the credentials (struct ucred *p_ucred;) are stored in proc ! Is there an esay way to get a struct thread* from a struct proc* ? or should I simply use the function: int suser_cred(struct ucred *cred, int flag); with cred =3D p-> p_ucred BTW what would the value of flag be? Thanks, -aziz
