2025-03-23Trusty: Fix build for anonymous pipes and std::sys::processThalia Archibald-2/+0
PRs #136842 (Add libstd support for Trusty targets), #137793 (Stablize anonymous pipe), and #136929 (std: move process implementations to `sys`) merged around the same time, so update Trusty to take them into account.

std: move process implementations to `sys` As per #117276, this moves the implementations of `Process` and friends out of the `pal` module and into the `sys` module, removing quite a lot of error-prone `#[path]` imports in the process (hah, get it ;-)). I've also made the `zircon` module a dedicated submodule of `pal::unix`, hopefully we can move some other definitions there as well (they are currently quite a lot of duplications in `sys`). Also, the `ensure_no_nuls` function on Windows now lives in `sys::pal::windows` – it's not specific to processes and shared by the argument implementation.

Add stack overflow handler for cygwin The cygwin runtime handles stack overflow exception and converts it to `SIGSEGV`, but the passed `si_addr` is obtained from `ExceptionInformation[1]` which is actually an undocumented value when stack overflows. Thus I choose to use Windows API directly to register handler, just like how std does on native Windows. The code is basically copied from the Windows one.

uefi: fs: Implement exists Also adds the initial file abstractions. The file opening algorithm is inspired from UEFI shell. It starts by classifying if the Path is Shell mapping, text representation of device path protocol, or a relative path and converts into an absolute text representation of device path protocol. After that, it queries all handles supporting EFI_SIMPLE_FILE_SYSTEM_PROTOCOL and opens the volume that matches the device path protocol prefix (similar to Windows drive). After that, it opens the file in the volume using the remaining pat. It also introduces OwnedDevicePath and BorrowedDevicePath abstractions to allow working with the base UEFI and Shell device paths efficiently. DevicePath in UEFI behaves like an a group of nodes laied out in the memory contiguously and thus can be modeled using iterators. This is an effort to break the original PR (https://github.com/rust-lang/rust/pull/129700) into much smaller chunks for faster upstreaming.

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). Please let me know if there's any additional context I need to add.
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/+23
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``````

uefi: Add Service Binding Protocol abstraction - Some UEFI protocols such as TCP4, TCP6, UDP4, UDP6, etc are managed by service binding protocol. - A new instance of such protocols is created and destroyed using the corresponding service binding protocol. - This PR adds abstractions to make using such protocols simpler using Rust Drop trait. - The reason to add these abstractions in a seperate PR from TCP4 Protocol is to make review easier.

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
