You can't ever safely map a single page and then map a superpage sized mapping over it with MAP_FIXED. Even in a single-threaded program, ASLR might mean you land too close to another mapping and on CheriBSD we don't allow the initial reservation to grow because doing so requires program changes that are hard to automate. To avoid this, map the entire region we want to use upfront. Reviewed by: markj Obtained from: CheriBSD Sponsored by: DARPA Differential Revision: https://reviews.freebsd.org/D43282 |
