We need to check for stack overflow only when the signal is on stack.
So we can improve the patch "http://lkml.org/lkml/2007/11/27/101"; as
following.
thanks, applied.
These patches change the behaviour of programs that longjmp out of a
signal handler on an alternate stack, don't they?
I'm interested to know what gave you confidence that changing that
behaviour won't break existing working programs.
Shouldn't such programs use sigsetjmp/siglongjmp, which should reset the
signal stack state?
