I didn't get this. Sorry for confusion... I meant, if only exec*( could race with _register(), we could add another uprobe hook which updates all (delayed) counters before return to user-mode. > > Afaics, the really problematic case is dlopen() which can race with _register() > > too, right? > > dlopen() should internally use mmap() right? So what is the problem here? Can > you please elaborate. What I tried to say is that we can't avoid uprobe_mmap()->delayed_uprobe_install() because dlopen() can race with _register() too, just like exec. Oleg.
