Johannes Berg 47da29763e um: mm: check more comprehensively for stub changes ... If userspace tries to change the stub, we need to kill it, because otherwise it can escape the virtual machine. In a few cases the stub checks weren't good, e.g. if userspace just tries to mmap(0x100000 - 0x1000, 0x3000, ...) it could succeed to get a new private/anonymous mapping replacing the stubs. Fix this by checking everywhere, and checking for _overlap_, not just direct changes.
