OpenBSD may soon gain further memory protections: immutable userland mappings

=> ↺ OpenBSD may soon gain further memory protections: immutable userland mappings

My next attempt is to lock memory mappings. The current working name is mimmutable(void *addr, size_t len). This identifies all current mapped memory in a region, and tags the mappings. Such mappings can never be unmapped. No new mmap can be done on top of the mappings. And the permissions cannot be changed. Other than that, the underlying storage memory works fine, it is just the mapping that is locked.
