When a new stack is created, a red zone is typically created - * (actually, the red zone is simply left unmapped) above the top of the stack, - * such that the stack will not be able to grow all the way to the bottom of the - * next stack. This isn't fool-proof. It is possible for a stack to grow by a - * large amount, such that it grows into the next stack, and as long as the - * memory within the red zone is never accessed, nothing will prevent one thread - * stack from trouncing all over the next. - * - * low memory - * . . . . . . . . . . . . . . . . . . - * | | - * | stack 3 | start of 3rd thread stack - * +-----------------------------------+ - * | | - * | Red Zone (guard page) | red zone for 2nd thread - * | | - * +-----------------------------------+ - * | stack 2 - _pthread_stack_default | top of 2nd thread stack - * | | - * | | - * | | - * | | - * | stack 2 | - * +-----------------------------------+ <-- start of 2nd thread stack - * | | - * | Red Zone | red zone for 1st thread - * | | - * +-----------------------------------+ - * | stack 1 - _pthread_stack_default | top of 1st thread stack - * | | - * | | - * | | - * | | - * | stack 1 | - * +-----------------------------------+ <-- start of 1st thread stack - * | | (initial value of last_stack) - * | Red Zone | - * | | red zone for main thread - * +-----------------------------------+ - * | USRSTACK - _pthread_stack_initial | top of main thread stack - * | | ^ - * | | | - * | | | - * | | | stack growth - * | | - * +-----------------------------------+ <-- start of main thread stack - * (USRSTACK) - * high memory - * - */ -static void * last_stack; - -void * -_thread_stack_alloc(size_t stacksize, size_t guardsize) -{ - void *stack = NULL; - struct stack *spare_stack; - size_t stack_size; - - /* - * Round up stack size to nearest multiple of _pthread_page_size, - * so that mmap() * will work.
