The lifetime of those mapping are not tied to the lifetime of the - process. If those memories are sealed from userspace, then munmap() will fail, - causing leaks in VMA address space during the lifetime of the process. - -- Brk (heap) - - Currently, userspace applications can seal parts of the heap by calling - malloc() and mseal(). - let's assume following calls from user space: - - - ptr = malloc(size); - - mprotect(ptr, size, RO); - - mseal(ptr, size); - - free(ptr); - - Technically, before mseal() is added, the user can change the protection of - the heap by calling mprotect(RO). As long as the user changes the protection - back to RW before free(), the memory range can be reused. - - Adding mseal() into the picture, however, the heap is then sealed partially, - the user can still free it, but the memory remains to be RO. If the address - is re-used by the heap manager for another malloc, the process might crash - soon after. Therefore, it is important not to apply sealing to any memory - that might get recycled. - - Furthermore, even if the application never calls the free() for the ptr, - the heap manager may invoke the brk system call to shrink the size of the - heap. In the kernel, the brk-shrink will call munmap(). Consequently, - depending on the location of the ptr, the outcome of brk-shrink is - nondeterministic. - - -Additional notes: -================= As Jann Horn pointed out in [3], there are still a few ways to write -to RO memory, which is, in a way, by design. Those cases are not covered -by mseal(). If applications want to block such cases, sandbox tools (such as -seccomp, LSM, etc) might be considered. +to RO memory, which is, in a way, by design.
