Release Notes

nix-rust/nix (nix)

v0.31.1

Compare Source

Added

• termios: Add definition for IUCLC to supported platforms
  (#​2702)
• termios: Add definition for XCASE for supported platforms
  (#​2703)

v0.31.0

Compare Source

Added

• Added the UDP GSO/GRO socket options and CMsgs on Android. This includes the
  following types:

  • UdpGsoSegment
  • UdpGroSegment
  • ControlMessage::UdpGsoSegments
  • ControlMessageOwned::UdpGroSegments

  (#​2666)

• Define errno EWOULDBLOCK as an alias of EAGAIN to match the AIX libc
  definition. (#​2692)

• Enable module ifaddrs on GNU Hurd
  (#​2697)

• Add termios OutputFlags::OFILL for Linux, Android, Aix, Cygwin, Fuchsia,
  Haiku,
  GNU/Hurd, Nto, Redox, Illumos, Solaris and Apple OSes.
  (#​2701)

• add sync() for cygwin (#​2708)

Changed

• changed EpollEvent methods to be const
  (#​2656)
• Bumped libc to
  0.2.180
  (#​2724)

Fixed

• Fixed nix::sys::ptrace::syscall_info, which was not setting the data
  argument properly, causing garbage values to be returned.
  (#​2653)
• Cast the 'addr' argument of 'madvise()' to '*mut u8' on AIX to match the
  signature in the AIX libc.
  (#​2655)
• Fixed the Dir module on NTO, Solaris, Hurd, and possibly other platforms.
  The
  d_name field was not copied correctly on those platforms. For some other
  platforms, it could be copied incorrectly for files with very long pathnames.
  (#​2674)
• Fix the build on Illumos (#​2694)

Removed

• Removed Eq and PartialEq implementations from SigHandler, because they
  never worked reliably. The suggested alternative is matches!. For
  example:

  let h: SigHandler = ...
  if matches!(h, SigHandler::SigIgn) {
      ...
  }
  ``` ([#​2642](https://redirect.github.com/nix-rust/nix/pull/2642))
  

• Removed IFF_NOTRAILERS by NetBSD, as it has been removed upstream and from
  libc (#​2724)

  (#1668)
• Deprecated InetAddr and SockAddr in favor of SockaddrIn, SockaddrIn6,
  and SockaddrStorage.
  (#1684)
• Deprecated IpAddr, Ipv4Addr, and Ipv6Addr in favor of their equivalents
  from the standard library.
  (#1685)
• uname now returns a Result<UtsName> instead of just a UtsName and
  ignoring failures from libc. And getters on the UtsName struct now return
  an &OsStr instead of &str.
  (#1672)
• Replaced IoVec with IoSlice and IoSliceMut, and replaced IoVec::from_slice with
  IoSlice::new. (#1643)

Fixed

• InetAddr::from_std now sets the sin_len/sin6_len fields on the BSDs.
  (#1642)
• Fixed a panic in LinkAddr::addr. That function now returns an Option.

  FdSet::contains involving file descriptors outside of the range
  0..FD_SETSIZE.

  (#1465)
• Added IPV6_V6ONLY sockopt.
  (#1470)

  include sys::eventfd::eventfd and sys::eventfd::EfdFlagsfor Android
  builds.
  (#1481)
• Most enums that come from C, for example Errno, are now marked as
  #[non_exhaustive].
  (#1474)
• Many more functions, mostly contructors, are now const.
  (#1476)
  (#1492)
• sys::event::KEvent::filter now returns a Result instead of being
  infalliable. The only cases where it will now return an error are cases
  where it previously would've had undefined behavior.
  (#1484)
• Minimum supported Rust version is now 1.46.0.
  (#​1492)
• Rework UnixAddr to encapsulate internals better in order to fix soundness
  issues. No longer allows creating a UnixAddr from a raw sockaddr_un.
  (#​1496)
• Raised bitflags to 1.3.0 and the MSRV to 1.46.0.
  (#​1492)

Fixed

• posix_fadvise now returns errors in the conventional way, rather than as a
  non-zero value in Ok().

  (#1545)

Removed

• Removed a couple of termios constants on redox that were never actually
  supported.
  (#1483)

  for all platforms.
  (#1484)
• Removed support for 32-bit Apple targets, since they've been dropped by both
  Rustc and Xcode.
  (#1492)
• Deprecated SockAddr/InetAddr::to_str in favor of ToString::to_string
  (#1495)
• Removed SigevNotify on OpenBSD and Redox.
  (#1511)

[0.22.3] - 22 January 2022

Changed

• Relaxed the bitflags requirement from 1.3.1 to 1.1. This partially reverts
  #​1492. From now on, the MSRV is not guaranteed to work with all versions of
  all dependencies, just with some version of all dependencies.
  (#1607)

[0.22.2] - 28 September 2021

Fixed

• Fixed buffer overflow in unistd::getgrouplist.
  (#1545)
• Added more errno definitions for better backwards compatibility with
  Nix 0.21.0.
  (#1467)

[0.22.1] - 13 August 2021

Fixed

• Locked bitflags to < 1.3.0 to fix the build with rust < 1.46.0.

Removed

• Removed a couple of termios constants on redox that were never actually
  supported.
  (#1483)

[0.22.0] - 9 July 2021

Added

• Added if_nameindex (#1445)
• Added nmount for FreeBSD.
  (#1453)
• Added IpFreebind socket option (sockopt) on Linux, Fuchsia and Android.
  (#1456)
• Added TcpUserTimeout socket option (sockopt) on Linux and Fuchsia.
  (#1457)
• Added renameat2 for Linux
  (#1458)
• Added RxqOvfl support on Linux, Fuchsia and Android.
  (#1455)

Changed

• ptsname_r now returns a lossily-converted string in the event of bad UTF,
  just like ptsname.
  (#​1446)
• Nix's error type is now a simple wrapper around the platform's Errno. This
  means it is now Into<std::io::Error>. It's also Clone, Copy, Eq, and
  has a small fixed size. It also requires less typing. For example, the old
  enum variant nix::Error::Sys(nix::errno::Errno::EINVAL) is now simply
  nix::Error::EINVAL.
  (#​1446)

[0.21.2] - 29 September 2021

Fixed

• Fixed buffer overflow in unistd::getgrouplist.
  (#1545)

[0.21.1] - 13 August 2021

Fixed

• Locked bitflags to < 1.3.0 to fix the build with rust < 1.46.0.

Removed

• Removed a couple of termios constants on redox that were never actually
  supported.
  (#1483)

[0.21.0] - 31 May 2021

Added

• Added getresuid and getresgid
  (#1430)
• Added TIMESTAMPNS support for linux
  (#1402)
• Added sendfile64 (#1439)
• Added MS_LAZYTIME to MsFlags
  (#1437)

Changed

• Made forkpty unsafe, like fork
  (#1390)
• Made Uid, Gid and Pid methods from_raw and as_raw a const fn
  (#1429)
• Made Uid::is_root a const fn
  (#1429)
• AioCb is now always pinned. Once a libc::aiocb gets sent to the kernel,
  its address in memory must not change. Nix now enforces that by using
  std::pin. Most users won't need to change anything, except when using
  aio_suspend. See that method's documentation for the new usage.
  (#1440)
• LioCb is now constructed using a distinct LioCbBuilder struct. T
