2017-11-14Auto merge of #45896 - malbarbo:use-libc-const, r=alexcrichtonbors-50/+5
Use getrandom syscall for all Linux and Android targets. I suppose we can use it in all Linux and Android targets. In function `is_getrandom_available` is checked if the syscall is available (getrandom syscall was add in version 3.17 of Linux kernel), if the syscall is not available `fill_bytes` fallback to reading from `/dev/urandom`. Update libc to include getrandom related constants.

2017-11-09std: Avoid use of `libc` in portable modulesAlex Crichton-9/+9
This commit removes usage of the `libc` crate in "portable" modules like those at the top level and `sys_common`. Instead common types like `*mut u8` or `u32` are used instead of `*mut c_void` or `c_int` as well as switching to platform-specific functions like `sys::strlen` instead of `libc::strlen`.
2017-11-08std: Move the `cmath` module into the `sys` moduleAlex Crichton-0/+44
This commit moves the `f32::cmath` and `f64::cmath` modules into the `sys` module. Note that these are not publicly exported modules, simply implementation details. These modules are already platform-specific with shims on MSVC and this is mostly just a reflection of that reality. This should also help cut down on `#[cfg]` traffic if platforms are brought on which don't directly support these functions.
2017-11-08std: Change how EBADF is handled in `sys`Alex Crichton-1/+4
This commit removes the reexport of `EBADF_ERR` as a constant from libstd's portability facade, instead opting for a platform-specific function that specifically queries an `io::Error`. Not all platforms may have a constant for this, so it makes the intent a little more clear that a code need not be supplied, just an answer to a query.
2017-11-08std: Remove `rand` crate and moduleAlex Crichton-215/+76
This commit removes the `rand` crate from the standard library facade as well as the `__rand` module in the standard library. Neither of these were used in any meaningful way in the standard library itself. The only need for randomness in libstd is to initialize the thread-local keys of a `HashMap`, and that unconditionally used `OsRng` defined in the standard library anyway. The cruft of the `rand` crate and the extra `rand` support in the standard library makes libstd slightly more difficult to port to new platforms, namely WebAssembly which doesn't have any randomness at all (without interfacing with JS). The purpose of this commit is to clarify and streamline randomness in libstd, focusing on how it's only required in one location, hashmap seeds. Note that the `rand` crate out of tree has almost always been a drop-in replacement for the `rand` crate in-tree, so any usage (accidental or purposeful) of the crate in-tree should switch to the `rand` crate on crates.io. This then also has the further benefit of avoiding duplication (mostly) between the two crates!

2017-10-09Auto merge of #45041 - est31:master, r=alexcrichtonbors-29/+4
Remove support for the PNaCl target (le32-unknown-nacl) This removes support for the `le32-unknown-nacl` target which is currently supported by rustc on tier 3. Despite the "nacl" in the name, the target doesn't output native code (x86, ARM, MIPS), instead it outputs binaries in the PNaCl format. There are two reasons for the removal: * Google [has announced](https://blog.chromium.org/2017/05/goodbye-pnacl-hello-webassembly.html) deprecation of the PNaCl format. The suggestion is to migrate to wasm. Happens we already have a wasm backend! * Our PNaCl LLVM backend is provided by the fastcomp patch set that the LLVM fork used by rustc contains in addition to vanilla LLVM (`src/llvm/lib/Target/JSBackend/NaCl`). Upstream LLVM doesn't have PNaCl support. Removing PNaCl support will enable us to move away from fastcomp (#44006) and have a lighter set of patches on top of upstream LLVM inside our LLVM fork. This will help distribution packagers of Rust. Fixes #42420

2017-10-05replace libc::res_init with res_init_if_glibc_before_2_26Jack O'Connor-0/+83
The previous workaround for gibc's res_init bug is not thread-safe on other implementations of libc, and it can cause crashes. Use a runtime check to make sure we only call res_init when we need to, which is also when it's safe. See https://github.com/rust-lang/rust/issues/43592.

2017-09-15Retain suid/sgid/sticky bits in Metadata.permissionsTrevor Merrifield-3/+3
Most users would expect set_permissions(Metadata.permissions()) to be non-destructive. While we can't guarantee this, we can at least pass the needed info to chmod. Also update the PermissionsExt documentation to disambiguate what it contains, and to refer to the underlying value as `st_mode` rather than its type `mode_t`. Closes #44147
2017-09-14Auto merge of #43972 - TobiasSchaffner:std_clean, r=alexcrichtonbors-21/+504
Add the libstd-modifications needed for the L4Re target This commit adds the needed modifications to compile the std crate for the L4 Runtime environment (L4Re). A target for the L4Re was introduced in commit: c151220a84e40b65e45308cc0f3bbea4466d3acf In many aspects implementations for linux also apply for the L4Re microkernel. Some uncommon characteristics had to be resolved: * L4Re has no network funktionality * L4Re has a maximum stacksize of 1Mb for threads * L4Re has no uid or gid Co-authored-by: Sebastian Humenda <sebastian.humenda@tu-dresden.de>
2017-09-13Move default stack min size to thread implementationsTobias Schaffner-2/+7
The default min stack size value is smaller on l4re and therefore this value has to be different depending on the platform.
2017-09-10Auto merge of #44220 - ↵bors-7/+15
kennytm:fix-44216-instance-plus-max-duration-should-panic, r=alexcrichton Properly detect overflow in Instance ± Duration. Fix #44216. Fix #42622 The computation `Instant::now() + Duration::from_secs(u64::max_value())` now panics. The call `receiver.recv_timeout(Duration::from_secs(u64::max_value()))`, which involves such time addition, will also panic. The reason #44216 arises is because of an unchecked cast from `u64` to `i64`, making the duration equivalent to -1 second. Note that the current implementation is over-conservative, since e.g. (-2⁶²) + (2⁶³) is perfectly fine for an `i64`, yet this is rejected because (2⁶³) overflows the `i64`.

2017-09-08Re-enable networking module fo rL4ReSebastian Humenda-1/+445
As suggested in the discussion of PR #43972, std should provide a uniform API to all platforms. Since there's no networking on L4Re, this now is a module in `sys::net` providing types and functions/methods returning an error for each action.

2017-09-08Match c_char definitions and enable signal reset for L4ReSebastian Humenda-13/+17
* Match definition of c_char in os/raw.rs with the libc definition Due to historic reasons, os/raw.rs redefines types for c_char from libc, but these didn't match. Now they do :). * Enable signal reset on exec for L4Re L4Re has full signal emulation and hence it needs to reset the signal set of the child with sigemptyset. However, gid and uid should *not* be set.
2017-09-07Properly detect overflow in Instance +/- Duration.kennytm-7/+15
Avoid unchecked cast from `u64` to `i64`. Use `try_into()` for checked cast. (On Unix, cast to `time_t` instead of `i64`.)
