Johannes Berg 5b5d760280 um: mm: check more comprehensively for stub changes ... commit 47da29763ec9a153b9b685bff9db659e4e09e494 upstream. 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.
