The following warnings were discovered during the build. These warnings are an
indication that the packages contain code that will become an error in a
future release of Rust. These warnings typically cover changes to close
soundness problems, unintended or undocumented behavior, or critical problems
that cannot be fixed in a backwards-compatible fashion, and are not expected
to be in wide use.
Each warning should contain a link for more information on what the warning
means and how to resolve it.
To solve this problem, you can try the following approaches:
- If the issue is not solved by updating the dependencies, a fix has to be
implemented by those dependencies. You can help with that by notifying the
maintainers of this problem (e.g. by creating a bug report) or by proposing a
fix to the maintainers (e.g. by creating a pull request):
- linux-loader@0.8.1
- Repository: https://github.com/rust-vmm/linux-loader
- Detailed warning command: `cargo report future-incompatibilities --id 2 --package linux-loader@0.8.1`
- If waiting for an upstream fix is not an option, you can use the `[patch]`
section in `Cargo.toml` to use your own version of the dependency. For more
information, see:
https://doc.rust-lang.org/cargo/reference/overriding-dependencies.html#the-patch-section
The package `linux-loader v0.8.1 (/workdir)` currently triggers the following future incompatibility lints:
> warning: reference to packed field is unaligned
> --> src/loader_gen/x86_64/bootparam.rs:383:18
> |
> 383 | unsafe { &(*(::std::ptr::null::<screen_info>())).ext_mem_k as *const _ as usize },
> | ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
> |
> = warning: this was previously accepted by the compiler but is being phased out; it will become a hard error in a future release!
> = note: for more information, see issue #82523 <https://github.com/rust-lang/rust/issues/82523>
> = note: fields of packed structs are not properly aligned, and creating a misaligned reference is undefined behavior (even if that reference is never dereferenced)
> = help: copy the field contents to a local variable, or replace the reference with a raw pointer and use `read_unaligned`/`write_unaligned` (loads and stores via `*p` must be properly aligned even when using raw pointers)
> note: the lint level is defined here
> --> src/loader_gen/mod.rs:14:40

...
reports 121 unaligned warnings (
warning: reference to packed field is unaligned) that will become errors in future Rust versions and should be fixed.
