2022-08-20Rollup merge of #100129 - RalfJung:miri-test-libstd, r=thomccMatthias Krüger-33/+82
add miri-test-libstd support to libstd - The first commit mirrors what we already have in liballoc. - The second commit adds some regression tests that only really make sense to be run in Miri, since they rely on Miri's extra checks to detect anything. - The third commit makes the MPSC tests work in reasonable time in Miri by reducing iteration counts. - The fourth commit silences some warnings due to code being disabled with `cfg(miri)`
2022-08-20Rollup merge of #97963 - devnexen:net_listener_neg, r=the8472Matthias Krüger-2/+10

2022-08-20Rollup merge of #100710 - ChrisDenton:load-library, r=thomccMatthias Krüger-81/+93
Windows: Load synch functions together Attempt to load all the required sync functions and fail if any one of them fails. This fixes a FIXME by going back to optional loading of `WakeByAddressSingle`. Also reintroduces a macro for optional loading of functions but keeps it separate from the fallback macro rather than having that do two different jobs. r? `@thomcc`
2022-08-20Rollup merge of #100642 - mzohreva:mz/update-sgx-abi-cancel-queue, ↵Matthias Krüger-5/+32
r=Mark-Simulacrum Update fortanix-sgx-abi and export some useful SGX usercall traits Update `fortanix-sgx-abi` to 0.5.0 to add support for cancel queue (see https://github.com/fortanix/rust-sgx/pull/405 and https://github.com/fortanix/rust-sgx/pull/404). Export some useful traits for processing SGX usercall. This is needed for https://github.com/fortanix/rust-sgx/pull/404 to avoid duplication. cc `@raoulstrackx` and `@jethrogb`
2022-08-20Rollup merge of #99544 - dylni:expose-utf8lossy, r=Mark-SimulacrumMatthias Krüger-17/+32
Expose `Utf8Lossy` as `Utf8Chunks` This PR changes the feature for `Utf8Lossy` from `str_internals` to `utf8_lossy` and improves the API. This is done to eventually expose the API as stable. Proposal: rust-lang/libs-team#54 Tracking Issue: #99543

2022-08-20Rollup merge of #100729 - thomcc:less-initialized, r=ChrisDentonMatthias Krüger-5/+13
Avoid zeroing a 1kb stack buffer on every call to `std::sys::windows::fill_utf16_buf` I've also tried to be slightly more careful about integer overflows, although in practice this is likely still not handled ideally. r? `@ChrisDenton`

Mitigate stale data reads on SGX platform Intel disclosed the Stale Data Read vulnerability yesterday. In order to mitigate this issue completely, reading userspace from an SGX enclave must be aligned and in 8-bytes chunks.

promote debug_assert to assert when possible and useful This PR fixed a very old issue https://github.com/rust-lang/rust/issues/94705 to clarify and improve the POSIX error checking, and some of the checks are skipped because can have no benefit, but I'm sure that this can open some interesting discussion.
