Woohoo! This looks very nice! Your current implementation matches, at least
conceptually, pretty closely the trusted pid patch I originally posted. You
have added some extra checks for the situation where another process has
taken the same pid. I am happy!
I'd like to clarify how the "relatives" check is done. It seems to me that
the while loop below would step up thru the process family hierarchy until it
finds a process that is its own parent. What kind of a process is that?
static inline struct task_struct* get_root_parent(struct task_struct *p)
{
struct task_struct *ts = p;
while (1)
{
if (ts == NULL)
return NULL;
if (ts->p_pptr == NULL)
return ts;
if (ts == ts->p_pptr)
return ts;
if (ts->p_pptr == ts->p_pptr->p_pptr)
return ts;
ts = ts->p_pptr;
}
}
