Stack-register Checking - March 10, 2018, 12:08 am UTC

Recently, Theo de Raadt ([email protected])
a new type of mitigation he has been working on together with Stefan Kempf ([email protected]):

How about we add another new permission!  This is not a hardware
permission, but a software permission. It is opportunistically
enforced by the kernel.

the permission is MAP_STACK. If you want to use memory as a stack,
you must mmap it with that flag bit. The kernel does so automatically
for the stack region of a process's stack. Two other types of stack
occur: thread stacks, and alternate signal stacks. Those are handled
in clever ways.

When a system call happens, we check if the stack-pointer register
points to such a page. If it doesn't, the program is killed. We
have tightened the ABI. You may no longer point your stack register
at non-stack memory. You'll be killed. This checking code is MI, so
it works for all platforms.

For more detail, see Theo's
original message.
