2025-03-13Remove has_redox_schemebjorn3-4/+1
Redox OS is moving away from name:/path style paths to /scheme/name/path style paths which are already handled correctly without has_redox_scheme.
2025-03-13Remove usage of legacy scheme paths on RedoxOSbjorn3-3/+6
The name:/path path syntax is getting phased out in favor of /scheme/name/path. Also using null: is no longer necessary as /dev/null is available on Redox OS too.

Implement `read_buf` and vectored read/write for SGX stdio Implement `read_buf`, `read_vectored`, and `write_vectored` for the SGX stdio types. Additionally, extend `User<T>::copy_to_enclave` to work for copying to uninitialized values and fix unsoundness in `UserRef<[T]>::copy_to_enclave_vec`. cc ``@jethrogb`` Tracked in https://github.com/rust-lang/rust/issues/136756

Add libstd support for Trusty targets This PR adds support for `alloc` and `std` for the Trusty targets based on the internal patches used in Android. The original patches can be seen [here](https://android.googlesource.com/toolchain/android_rust/+/refs/heads/main/patches/development/rustc-0023-Add-Trusty-OS-support-to-Rust-std.patch) and [here](https://android.googlesource.com/toolchain/android_rust/+/refs/heads/main/patches/development/rustc-0054-Add-std-os-fd-support-for-Trusty.patch).

2025-03-11Fix `UserRef<[T]>::copy_to_enclave_vec`Thalia Archibald-13/+6
It reinterprets uninitialized memory as initialized and does not drop existing elements of the Vec. Fix that. Additionally, make it more general by appending, instead of overwriting existing elements, and rename it to `append_to_enclave_vec`. A caller can simply call `.clear()` before, for the old behavior.

2025-03-11Rollup merge of #138002 - 1c3t3a:fix-std-cfi-violation, r=rcvalleMatthias Krüger-0/+37
Disable CFI for weakly linked syscalls Currently, when enabling CFI via -Zsanitizer=cfi and executing e.g. std::sys::random::getrandom, we can observe a CFI violation. This is the case for all consumers of the std::sys::pal::weak::syscall macro, as it is defining weak functions which don't show up in LLVM IR metadata. CFI fails for all these functions. Similar to other such cases in https://github.com/rust-lang/rust/issues/115199, this change stops emitting the CFI typecheck for consumers of the macro via the `#[no_sanitize(cfi)]` attribute. r? ``````@rcvalle``````

As per #117276, this moves the platform definitions of `Stdout` and friends into `sys`. This PR also unifies the UNIX and Hermit implementations and moves the `__rust_print_err` function needed by libunwind on SGX into the dedicated module for such helper functions.

2025-03-07Rollup merge of #137777 - thaliaarchi:os_string-push-str, r=joboetMatthias Krüger-0/+10
Specialize `OsString::push` and `OsString as From` for UTF-8 When concatenating two WTF-8 strings, surrogate pairs at the boundaries need to be joined. However, since UTF-8 strings cannot contain surrogate halves, this check can be skipped when one string is UTF-8. Specialize `OsString::push` to use a more efficient concatenation in this case. The WTF-8 version of `OsString` tracks whether it is known to be valid UTF-8 with its `is_known_utf8` field. Specialize `From<AsRef<OsStr>>` so this can be set for UTF-8 string types. Unfortunately, a specialization for `T: AsRef<str>` conflicts with `T: AsRef<OsStr>`, so stamp out string types with a macro. r? ``@ChrisDenton``

2025-03-05Rollup merge of #137463 - sunshowers:illumos-posix-spawn, r=Mark-Simulacrum许杰友 Jieyou Xu (Joe)-1/+16
[illumos] attempt to use posix_spawn to spawn processes illumos has `posix_spawn`, and the very newest versions also have `_addchdir`, so use that. POSIX standardized this function so I also added a weak symbol lookup for the non `_np` version. (illumos has both.) This probably also works on Solaris, but I don't have access to an installation to validate this so I decided to focus on illumos instead. This is a nice ~4x performance improvement for process creation. My go-to as usual is nextest against the clap repo, which acts as a stress test for process creation -- with [this commit]: ```console $ cargo nextest run -E 'not test(ui_tests) and not test(example_tests)' before: Summary [ 1.747s] 879 tests run: 879 passed, 2 skipped after: Summary [ 0.445s] 879 tests run: 879 passed, 2 skipped ``` [this commit]: https://github.com/clap-rs/clap/commit/fde45f9aea766fb8de46e3d46e6575f393c3b6b9

2025-03-01Rollup merge of #137809 - Noratrieb:io-error-casing, r=thomccMatthias Krüger-70/+70
Use correct error message casing for `io::const_error`s Error messages are supposed to start with lowercase letters, but a lot of `io::const_error` messages did not. This fixes them to start with a lowercase letter. I did consider adding a const check for this to the macro, but some of them start with proper nouns that make sense to uppercase them. See https://doc.rust-lang.org/1.85.0/std/error/trait.Error.html
