force_sig_info_to_task

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

spin_lock_irqsave( & siglock, flags)

1312

action = action[sig - 1]

1313

ignored = sa_handler == gnore signal

1314

blocked = sigismember( & blocked, sig)

1315

If blocked || ignored Then

1316

sa_handler = default signal handling

1317

If blocked Then

1318

sigdelset( & blocked, sig)

1319

After recalculating TIF_SIGPENDING, we need to make sure the task wakes up.* This is superfluous when called on current, the wakeup is a harmless no-op.

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
