Name:Force a signal that the process can't ignore: if necessary* we unblock the signal and change any SIG_IGN to SIG_DFL.* Note: If we unblock the signal, we always reset it to SIG_DFL,* since we do not want to have a signal handler that was blocked
Proto:static int force_sig_info_to_task(struct kernel_siginfo *info, struct task_struct *t)
Type:int
Parameter:
Type | Parameter | Name |
---|---|---|
struct kernel_siginfo * | info | |
struct task_struct * | t |
1311 | spin_lock_irqsave( & siglock, flags) |
1313 | ignored = sa_handler == gnore signal |
1314 | blocked = sigismember( & blocked, sig) |
1317 | If blocked Then |
1326 | If sa_handler == default signal handling && Not ptrace Then Per task flags (PF_*), defined further below: &= ~r init: ignore fatal signals |
1328 | ret = send_signal(sig, info, t, PIDTYPE_PID) |
1329 | spin_unlock_irqrestore( & siglock, flags) |
1331 | Return ret |
