2020-05-17Remove temporarily the failing tests for RedoxXavier L'Heureux
TODO: Fix them in Relibc
2020-05-17Add termio supportXavier L'Heureux
2020-05-17Remove more unsupported functions and make it possible to run testsXavier L'Heureux
2020-05-17Add Redox support for most of the modulesXavier L'Heureux
Some things are not implemented yet in redox, so a lot of annotations were added to remove functions when compiling for redox. Those functions will hopefully be added in time, but for now it's better to have partial support than none. Blocked by https://github.com/rust-lang/libc/pull/1438
2020-05-17Replace void crate with Rust standard lib Infallible typeOssi Herrala
std::convert::Infallible has been available since Rust 1.34 and nix currently targets Rust 1.36 or later so this should not cause problems. Fixes #1238

1242: Don't implement `NixPath` for `Option<&P> where P: NixPath` r=asomers a=asomers Most Nix functions that accept `NixPath` arguments can't do anything useful with `None`. The exceptions (`mount` and `quotactl_sync`) already take explicitly optional arguments. Also, this changes the behavior of `mount` with `None` arguments. Previously, it would call mount(2) with empty strings for those arguments. Now, it will use null pointers. Co-authored-by: Alan Somers <asomers@gmail.com>

1245: Make ptrace::write unsafe on Linux r=asomers a=asomers It always should've been unsafe, because it dereferences a user-provided pointer. Co-authored-by: Alan Somers <asomers@gmail.com>
2020-05-16Make ptrace::write unsafe on LinuxAlan Somers
It always should've been unsafe, because it dereferences a user-provided pointer.
2020-05-16Apply `repr(transparent)` to several FFI typesAlan Somers
repr(transparent) is required in order to safely cast between an FFI type and its NewType. This commit applies that attribute to PollFd, EpollEvent, IpMembershipRequest, Ipv6MembershipRequest, TimeVal, and IoVec. Fixes #1241

2020-05-08Add SO_BINDTODEVICE sockoptJean Pierre Dudey
This is available only on Linux as far I know, [socket(7)](https://linux.die.net/man/7/socket) has some information about the `SO_BINDTODEVICE` sockopt. In simple words it binds a socket to an specific network device (specified as an string like "wlo1", "eth0", etc.), to only process packets from that device.

1209: Support UDP GSO and GRO on linux r=asomers a=glebpom This PR implements support for UDP GSO and GRO on Linux. It provides the way to send/receive UDP payloads bigger than interface MTU. The goal is to improve UDP performance. GSO was introduced in Linux 4.18, GRO in 5.3 Co-authored-by: Gleb Pomykalov <gleb@lancastr.com>

1207: Add select::FdSet::fds() method r=asomers a=zombiezen To be more consistent with most Rust APIs and enable cloning of the iterator, I made `FdSet::contains` operate on an immutable borrow instead of a mutable one by copying the set. If this is not desirable, I can roll that back from this PR and focus purely on the `fds()` method. Co-authored-by: Ross Light <ross@zombiezen.com>

1206: Fix unaligned casting of cmsg data to af_alg_iv r=asomers a=glebpom Casting a pointer to `cmsg_data` to `af_alg_iv` is incorrect since it's not properly aligned. As of the [`cmsg` man page](http://man7.org/linux/man-pages/man3/cmsg.3.html) "Applications should not cast it to a pointer type matching the payload, but should instead use memcpy(3) to copy data to or from a suitably declared object."

2020-04-12Fix UB in getsockoptAlan Somers
The old code tried to zero-initialize an enum for which 0 is not a valid value. That worked for older compilers, but triggers a panic with Rust 1.44.0. The correct technique is to use mem::MaybeUninit. Fixes #1212

ignore really is the correct things to do for these doc tests. compile_fail should only be used for examples that demonstrate a compile failure by design, not for stuff that only works on one platform.
