Purpose

  • munmap_syscall blindly called mmap(MAP_FIXED|PROT_NONE) over the rounded-up byte range without checking what pages the caller actually owns. When the rounded length extended into an adjacent shm page, it got wiped.
  • Now intersects the requested range with vmmap entries and only PROT_NONEs pages belonging to anonymous mappings. SharedMemory-backed entries are left to shmdt.
  • Fixes the dead read-lock/drop at the top of the function (the lock is now a single write lock used for both lookup and mutation).

Fixes #1062 and #1052

Concern

I was reading Linux's behavior around this un-mapping logic and it seems like for the calling process, the kernel would unlink even the shared memory reference (alongside the anonymous backed region). In our case, we simply ignore that problem.
I suspect this could cause a divergence in the state of shm at the cage level. However, I couldn't conceptualize/didn't invest enough time to read how that state works.
I was also reading that it is unlikely for VMAs of anonymous and shared memory being adjacent to each other.

Please let me know if I should dig deeper if this fix isn't optimal for our use-case.

This is a really good find/PR. Thanks @rishabhBudhouliya.

It would be good to add a test that would have failed before this fix to confirm this.

As for your questions, I think the inconsistency is only visible if the same cage tries to re-access the address after munmap, which is undefined behavior anyway. I don't think we really need to worry about that.
