| |
Hi,
I had a look and the panic actually happens in collect_signal() in here:
static inline int collect_signal(int sig, struct sigpending *list, siginfo_t *info) { if (sigismember(&list->signal, sig)) { /* Collect the siginfo appropriate to this signal. */ struct sigqueue *q, **pp; pp = &list->head; while ((q = *pp) != NULL) { q becomes 0x5a5a5a5a ^^^^^^^^^ if (q->info.si_signo == sig) 0x5a5a5a5a is dereferenced ^^^^^^^^^^^^^^^^ goto found_it; pp = &q->next; }
Hope this helps.
Best regards,
Anton
