Hi, Sorry for my english. I started learn assembly again after 15 years. Now, I'm learning about memory management and sys_brk system call. I've created a really simple program, which try to extend the heap size. I've read, when sys_brk is called with the new break address(last usable address of the heap or data segment), it will be rounded up to the next nearest page, but it didn't. Am I misundestand somthing?
I've noticed this. Seems to be related to kernel version (220.127.116.11 here). May be a "bug"? I think you can access memory up to the top of the page (what you/we would "expect" brk to return). I don't know what to make of it.
