    🔄 Changed

    • mqueue functions now operate on a distinct type, nix::mqueue::MqdT. Accessors take this type by reference, not by value. (#1639)
    • ✂ Removed SigSet::extend in favor of <SigSet as Extend<Signal>>::extend. Because of this change, you now need use std::iter::Extend to call extend on a SigSet. (#1553)
    • ✂ Removed the the PATH_MAX restriction from APIs accepting paths. Paths will now be allocated on the heap if they are too long. In addition, large instruction count improvements (~30x) were made to path handling. (#1656)
    • 🔄 Changed getrlimit and setrlimit to use rlim_t directly instead of Option<rlim_t>. (#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. (#1675) (#1677)

    ✂ Removed

    • ✂ Removed public access to the inner fields of NetlinkAddr, AlgAddr, SysControlAddr, LinkAddr, and VsockAddr. (#1614)
    • ✂ Removed EventFlag::EV_SYSFLAG. (#1635)

  • v0.23.1 Changes

    December 16, 2021

    ➕ Added

    🔄 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)

    🛠 Fixed

    • 🛠 Fixed soundness issues in FdSet::insert, FdSet::remove, and FdSet::contains involving file descriptors outside of the range 0..FD_SETSIZE. (#1575)

    • ➕ Added IPV6_V6ONLY sockopt. (#1470)
    • ➕ Added impl From<User> for libc::passwd trait implementation to convert a User into a libc::passwd. Consumes the User struct to give ownership over the member pointers. (#1471)
    • ➕ Added pthread_kill. (#1472)
    • ➕ Added mknodat. (#1473)
    • ➕ Added setrlimit and getrlimit. (#1302)

    • ➕ Added Ipv4RecvErr and Ipv6RecvErr sockopts and associated control messages. (#1514)
    • ➕ Added AsRawFd implementation on PollFd. (#1516)
    • ➕ Added Ipv4Ttl and Ipv6Ttl sockopts. (#1515)

    🔄 Changed

    • FdSet::{contains, highest, fds} no longer require a mutable reference. (#1464)
    • 👍 User::gecos and corresponding libc::passwd::pw_gecos are supported on 64-bit Android, change conditional compilation to include the field in 64-bit Android builds (#1471)
    • 👍 eventfds are supported on Android, change conditional compilation to 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(). (#1538)
    • ➕ Added more errno definitions for better backwards compatibility with Nix 0.21.0. (#1467)
    • 🛠 Fixed potential undefined behavior in Signal::try_from on some platforms. (#1484)
    • 🛠 Fixed buffer overflow in unistd::getgrouplist. (#1545)

    ✂ Removed

    • ✂ Removed a couple of termios constants on redox that were never actually supported. (#1483)
    • ✂ Removed nix::sys::signal::NSIG. It was of dubious utility, and not correct 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)

  • v0.22.0 Changes

    July 09, 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)

    🛠 Fixed

    ✂ Removed

  • v0.21.0 Changes

    May 31, 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. This avoids a soundness issue with the old LioCb. Usage is similar but construction now uses the builder pattern. See the documentation for details. (#1440)
    • 👍 Minimum supported Rust version is now 1.41.0. (#1440)
    • Errno aliases are now associated consts on Errno, instead of consts in the errno module. (#1452)

    🛠 Fixed

    • 👍 Allow sockaddr_ll size, as reported by the Linux kernel, to be smaller then it's definition (#1395)
    • 🛠 Fix spurious errors using sendmmsg with multiple cmsgs (#1414)
    • ➕ Added Errno::EOPNOTSUPP to FreeBSD, where it was missing. (#1452)

    ✂ Removed

    • ✂ Removed sys::socket::accept4 from Android arm because libc removed it in version 0.2.87. (#1399)
    • AioCb::from_boxed_slice and AioCb::from_boxed_mut_slice have been removed. They were useful with earlier versions of Rust, but should no longer be needed now that async/await are available. AioCbs now work exclusively with borrowed buffers, not owned ones. (#1440)
    • ✂ Removed some Errno values from platforms where they aren't actually defined. (#1452)

  • v0.20.0 Changes

    • execv, execve, execvp and execveat in ::nix::unistd and reboot in ::nix::sys::reboot now return Result<Infallible> instead of Result<Void> (#1239)
    • sys::socket::sockaddr_storage_to_addr is no longer unsafe. So is offset_of!.
    • sys::socket::sockaddr_storage_to_addr, offset_of!, and Errno::clear are no longer unsafe.
    • SockAddr::as_ffi_pair,sys::socket::sockaddr_storage_to_addr, offset_of!, and Errno::clear are no longer unsafe. (#1244)
    • Several Inotify methods now take self by value instead of by reference (#1244)
    • 📊 nix::poll::ppoll: timeout parameter is now optional, None is equivalent for infinite timeout.

    🛠 Fixed

    • 🛠 Fixed getsockopt. The old code produced UB which triggers a panic with Rust 1.44.0. (#1214)

    • 🛠 Fixed a bug in nix::unistd that would result in an infinite loop when a group or user lookup required a buffer larger than 16KB. (#1198)

    ✂ Removed

    • Removed sys::socket::addr::from_libc_sockaddr from the public API. (#1215)

    • Nix no longer implements NixPath for Option<P> where P: NixPath. 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. (#1242)

    • ✂ Removed unistd::daemon and unistd::pipe2 on OSX and ios (#1255)

    • Removed sys::event::FilterFlag::NOTE_EXIT_REPARENTED and sys::event::FilterFlag::NOTE_REAP on OSX and ios. (#1255)
