Pounds of miri provenance errors #957

Closed SUPERCILEX closed 1 year ago

SUPERCILEX commented 1 year ago

Not sure if this is solvable on stable yet, but there are quite a few miri errors.

warning: integer-to-pointer cast
   --> /home/runner/.cargo/registry/src/github.com-1ecc6299db9ec823/crossbeam-epoch-0.9.13/src/atomic.rs:[204](https://github.com/SUPERCILEX/ftzz/actions/runs/4039367309/jobs/6944029052#step:5:205):11

204 |         &*(ptr as *const T)
    |           ^^^^^^^^^^^^^^^^^ integer-to-pointer cast
    |
    = help: This program is using integer-to-pointer casts or (equivalently) `ptr::from_exposed_addr`,
    = help: which means that Miri might miss pointer bugs in this program.
    = help: See https://doc.rust-lang.org/nightly/std/ptr/fn.from_exposed_addr.html for more details on that operation.
    = help: To ensure that Miri does not miss bugs in your program, use Strict Provenance APIs (https://doc.rust-lang.org/nightly/std/ptr/index.html#strict-provenance, https://crates.io/crates/sptr) instead.
    = help: You can then pass the `-Zmiri-strict-provenance` flag to Miri, to ensure you are not relying on `from_exposed_addr` semantics.
    = help: Alternatively, the `-Zmiri-permissive-provenance` flag disables this warning.

I believe the strict-provenance-related stuff has been fixed in the master (https://github.com/crossbeam-rs/crossbeam/pull/796). As for stacked-borrows-related stuff in the epoch, there is a fix in https://github.com/crossbeam-rs/crossbeam/pull/871, but feedback on the new API is needed.

Closing as already fixed.
