Obviate #[allow(improper_ctypes_definitions)] Modifies the return type for `fn entry` so that allowing improper_ctypes_definitions is no longer necessary. This change is derived from a similar pattern in `libstd/sys/sgx/abi/usercalls/raw.rs` with `UsercallReturn`. cc @jethrogb

Fortanix SGX target libunwind build process changes Ticket: https://github.com/fortanix/rust-sgx/issues/174 LLVM related changes (merged): https://github.com/rust-lang/llvm-project/pull/57 Description: libunwind changes needed to run code in sgx environment via rust-sgx. Target that uses this in rust: x86_64-fortanix-unknown-sgx. Without this change, rust std for this toolchain is forced to use a precompiled library loaded via environment variable. With this change we act the same as musl target.
2020-06-24lints: add `improper_ctypes_definitions`David Wood-0/+1
This commit adds a new lint - `improper_ctypes_definitions` - which functions identically to `improper_ctypes`, but on `extern "C" fn` definitions (as opposed to `improper_ctypes`'s `extern "C" {}` declarations). Signed-off-by: David Wood <david@davidtw.co>

2020-06-18Prevent attacker from manipulating FPU tag word used in SGX enclaveRaoul Strackx-0/+7
Insufficient sanitization of the x87 FPU tag word in the trusted enclave runtime allowed unprivileged adversaries in the containing host application to induce incoherent or unexpected results for ABI-compliant compiled enclave application code that uses the x87 FPU. Vulnerability was disclosed to us by Fritz Alder, Jo Van Bulck, David Oswald and Frank Piessens

2019-11-29Format libstd/sys with rustfmtDavid Tolnay-131/+142
This commit applies rustfmt with rust-lang/rust's default settings to files in src/libstd/sys *that are not involved in any currently open PR* to minimize merge conflicts. THe list of files involved in open PRs was determined by querying GitHub's GraphQL API with this script: https://gist.github.com/dtolnay/aa9c34993dc051a4f344d1b10e4487e8 With the list of files from the script in outstanding_files, the relevant commands were: $ find src/libstd/sys -name '*.rs' \ | xargs rustfmt --edition=2018 --unstable-features --skip-children $ rg libstd/sys outstanding_files | xargs git checkout -- Repeating this process several months apart should get us coverage of most of the rest of the files. To confirm no funny business: $ git checkout $THIS_COMMIT^ $ git show --pretty= --name-only $THIS_COMMIT \ | xargs rustfmt --edition=2018 --unstable-features --skip-children $ git diff $THIS_COMMIT # there should be no difference

2019-02-13Auto merge of #58235 - jethrogb:jb/sgx-usercall-internals, r=alexcrichtonbors-80/+58
SGX target: simplify usercall internals This moves logic from assembly to Rust and removes the special case for exit/panic handling, merging it with regular usercall handling. Also, this fixes a bug in the exit usercall introduced in a75ae00. The bug would make regular exits look like panics with high probability. It would also with some probability leak information through uncleared registers. cc @VardhanThigle r? @alexcrichton
