Subjectpinpointed: PANIC caused by dequeue_signal() in current Linus BK tree
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
