offset_from: always allow pointers to point to the same address #124921

RalfJung · 2024-05-09T10:54:28Z

This PR implements the last remaining part of the t-opsem consensus in rust-lang/unsafe-code-guidelines#472: always permits offset_from when both pointers have the same address, no matter how they are computed. This is required to achieve provenance monotonicity.

Tracking issue: #117945

What is provenance monotonicity and why does it matter?

Provenance monotonicity is the property that adding arbitrary provenance to any no-provenance pointer must never make the program UB. More specifically, in the program state, data in memory is stored as a sequence of abstract bytes, where each byte can optionally carry provenance. When a pointer is stored in memory, all of the bytes it is stored in carry that provenance. Provenance monotonicity means: if we take some byte that does not have provenance, and give it some arbitrary provenance, then that cannot change program behavior or introduce UB into a UB-free program.

We care about provenance monotonicity because we want to allow the optimizer to remove provenance-stripping operations. Removing a provenance-stripping operation effectively means the program after the optimization has provenance where the program before the optimization did not -- since the provenance removal does not happen in the optimized program. IOW, the compiler transformation added provenance to previously provenance-free bytes. This is exactly what provenance monotonicity lets us do.

We care about removing provenance-stripping operations because *ptr = *ptr is, in general, (likely) a provenance-stripping operation. Specifically, consider ptr: *mut usize (or any integer type), and imagine the data at *ptr is actually a pointer (i.e., we are type-punning between pointers and integers). Then *ptr on the right-hand side evaluates to the data in memory without any provenance (because integers do not have provenance). Storing that back to *ptr means that the abstract bytes ptr points to are the same as before, except their provenance is now gone. This makes *ptr = *ptr a provenance-stripping operation (Here we assume *ptr is fully initialized. If it is not initialized, evaluating *ptr to a value is UB, so removing *ptr = *ptr is trivially correct.)

What does `offset_from` have to do with provenance monotonicity?

With ptr = without_provenance(N), ptr.offset_from(ptr) is always well-defined and returns 0. By provenance monotonicity, I can now add provenance to the two arguments of offset_from and it must still be well-defined. Crucially, I can add different provenance to the two arguments, and it must still be well-defined. In other words, this must always be allowed: ptr1.with_addr(N).offset_from(ptr2.with_addr(N)) (and it returns 0). But the current spec for offset_from says that the two pointers must either both be derived from an integer or both be derived from the same allocation, which is not in general true for arbitrary ptr1, ptr2.

To obtain provenance monotonicity, this PR hence changes the spec for offset_from to say that if both pointers have the same address, the function is always well-defined.

What further consequences does this have?

It means the compiler can no longer transform end2 = begin.offset(end.offset_from(begin)) into end2 = end. However, it can still be transformed into end2 = begin.with_addr(end.addr()), which later parts of the backend (when provenance has been erased) can trivially turn into end2 = end.

The only alternative I am aware of is a fundamentally different handling of zero-sized accesses, where a "no provenance" pointer is not allowed to do zero-sized accesses and instead we have a special provenance that indicates "may be used for zero-sized accesses (and nothing else)". offset and offset_from would then always be UB on a "no provenance" pointer, and permit zero-sized offsets on a "zero-sized provenance" pointer. This achieves provenance monotonicity. That is, however, a breaking change as it contradicts what we landed in #117329. It's also a whole bunch of extra UB, which doesn't seem worth it just to achieve that transformation.

What about the backend?

LLVM currently doesn't have an intrinsic for pointer difference, so we anyway cast to integer and subtract there. That's never UB so it is compatible with any relaxation we may want to apply.

If LLVM gets a ptrsub in the future, then plausibly it will be consistent with ptradd and consider two equal pointers to be inbounds.

#117329 landed, so we can consider this now.

@nikic the only point that's giving me pause here are compatibility concerns with a potential future ptrsub operation in LLVM. If such an operation gets added, do you think there will be a variant of it (with the right flags set) that matches the semantics given in this PR? I think all the provenance monotonicity arguments also apply to LLVM, but it's hard to say as LLVM hasn't decided yet how integer-typed loads of data with provenance behave.

RalfJung · 2024-07-02T19:13:01Z

@nikic any thoughts?

In principle we don't need provenance monotonicity in Rust-the-surface language, we only need it in an IR that wants to do optimizations like removing redundant load-store roundtrips. However, I think it would also be desirable to be able to teach programmers that having provenance attached with some data is just giving that data "extra capabilities" (namely to be used as a pointer), and can never lose anything. Such symmetries can make complicated topics easier to understand. So I think if at all possible we should strive to achieve provenance monotonicity in our surface syntax -- which means we should land something like this PR.

nikic · 2024-07-03T10:57:53Z

@RalfJung I can't tell the future, but I would expect that if LLVM introduces "ptrsub inbounds" that the semantics would mirror those of "ptradd inbounds", which includes the "equal pointers are always inbounds" special case.

RalfJung · 2024-07-03T11:39:24Z

Thanks! It's a bit of a different case here since we have two pointers, and inbounds is relative to the provenance of a single pointer, so then one could ask -- what is the pointer for which the range between the two pointers has to be "inbounds"? But the most conservative option seems to be "both".

In fact I quite like this, it lets us frame all of offset_from, offset, and "dereferenceable" in terms of the same underlying predicate. Let's say a pointer p is dereferenceable for n bytes if either n == 0 or the allocation p points to is live and fully contains the range p.addr() .. (p.addr() + n). We extend this to negative n by using the range (p.addr() + n) .. p.addr() in case n < 0. Then we can define:

offset::<T>(p, i) requires p to be dereferenceable for i*size_of::<T>() bytes. This in particular implies that i*size_of::<T>() fits in an isize (as there is no allocation larger than that) and that adding i*size_of::<T>() does not overflow (as there is no allocation that crosses the edge of the address space).
for offset_from::<T>(p1, p2), let diff = p1.addr().wrapping_sub(p2.addr()) as isize; now we require p1 to be dereferenceable for -diff bytes and p2 to be dereferenceable for diff bytes. This in particular implies that the absolute distance fits in an isize (as there is no allocation larger than that).

So the offset_from requirement "p1 and p2 have to point to the same allocation" would actually not be a fundamental requirement, it would merely fall out of the fact that the only way two pointers can both be dereferenceable for the same non-empty memory range is for them to point to the same allocation.

raw_eq: using it on bytes with provenance is not UB (outside const-eval) The current behavior of raw_eq violates provenance monotonicity. See rust-lang#124921 for an explanation of provenance monotonicity. It is violated in raw_eq because comparing bytes without provenance is well-defined, but adding provenance makes the operation UB. So remove the no-provenance requirement from raw_eq. However, the requirement stays in-place for compile-time invocations of raw_eq, that indeed cannot deal with provenance. Cc `@rust-lang/opsem`

Rust plugin support has been deprecated for four years and was removed in 1.75.0.](rust-lang/cargo#13902) <a id="1.81.0-Compatibility-Notes"></a> ## Compatibility Notes - Usage of the `wasm32-wasi` target will now issue a compiler warning and request users switch to the `wasm32-wasip1` target instead. Both targets are the same, `wasm32-wasi` is only being renamed, and this [change to the WASI target](https://blog.rust-lang.org/2024/04/09/updates-to-rusts-wasi-targets.html) is being done to enable removing `wasm32-wasi` in January 2025. - We have renamed `std::panic::PanicInfo` to `std::panic::PanicHookInfo`. The old name will continue to work as an alias, but will result in a deprecation warning starting in Rust 1.82.0. `core::panic::PanicInfo` will remain unchanged, however, as this is now a *different type*. The reason is that these types have different roles: `std::panic::PanicHookInfo` is the argument to the [panic hook](https://doc.rust-lang.org/stable/std/panic/fn.set_hook.html) in std context (where panics can have an arbitrary payload), while `core::panic::PanicInfo` is the argument to the [`#[panic_handler]`](https://doc.rust-lang.org/nomicon/panic-handler.html) in no_std context (where panics always carry a formatted *message*). Separating these types allows us to add more useful methods to these types, such as `std::panic::PanicHookInfo::payload_as_str()` and `core::panic::PanicInfo::message()`. - The new sort implementations may panic if a type's implementation of [`Ord`](https://doc.rust-lang.org/std/cmp/trait.Ord.html) (or the given comparison function) does not implement a [total order](https://en.wikipedia.org/wiki/Total_order) as the trait requires. `Ord`'s supertraits (`PartialOrd`, `Eq`, and `PartialEq`) must also be consistent. The previous implementations would not "notice" any problem, but the new implementations have a good chance of detecting inconsistencies, throwing a panic rather than returning knowingly unsorted data. - [In very rare cases, a change in the internal evaluation order of the trait solver may result in new fatal overflow errors.](rust-lang/rust#126128) <a id="1.81.0-Internal-Changes"></a> ## Internal Changes These changes do not affect any public interfaces of Rust, but they represent significant improvements to the performance or internals of rustc and related tools. - [Add a Rust-for Linux `auto` CI job to check kernel builds.](rust-lang/rust#125209) </details> --- ### Configuration 📅 **Schedule**: Branch creation - At any time (no schedule defined), Automerge - At any time (no schedule defined). 🚦 **Automerge**: Disabled by config.

Separating these types allows us to add more useful methods to these types, such as `std::panic::PanicHookInfo::payload_as_str()` and `core::panic::PanicInfo::message()`. * The new sort implementations may panic if a type's implementation of [`Ord`](https://doc.rust-lang.org/std/cmp/trait.Ord.html) (or the given comparison function) does not implement a [total order](https://en.wikipedia.org/wiki/Total_order) as the trait requires. `Ord`'s supertraits (`PartialOrd`, `Eq`, and `PartialEq`) must also be consistent. The previous implementations would not "notice" any problem, but the new implementations have a good chance of detecting inconsistencies, throwing a panic rather than returning knowingly unsorted data. * [In very rare cases, a change in the internal evaluation order of the trait solver may result in new fatal overflow errors.] (rust-lang/rust#126128) Internal Changes ---------------- These changes do not affect any public interfaces of Rust, but they represent significant improvements to the performance or internals of rustc and related tools. - [Add a Rust-for Linux `auto` CI job to check kernel builds.] (rust-lang/rust#125209)

What is provenance monotonicity and why does it matter?

What does offset_from have to do with provenance monotonicity?

What further consequences does this have?

What about the backend?
