# Change Log All notable changes to this project will be documented in this file. This project adheres to [Semantic Versioning](https://semver.org/). ## [Unreleased] - ReleaseDate ### Added - Added the `LocalPeerCred` sockopt. (#[1482](https://github.com/nix-rust/nix/pull/1482)) - Added `TimeSpec::from_duration` and `TimeSpec::from_timespec` (#[1465](https://github.com/nix-rust/nix/pull/1465)) - Added `IPV6_V6ONLY` sockopt. (#[1470](https://github.com/nix-rust/nix/pull/1470)) - Added `impl From 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](https://github.com/nix-rust/nix/pull/1471)) - Added `pthread_kill`. (#[1472](https://github.com/nix-rust/nix/pull/1472)) - Added `mknodat`. (#[1473](https://github.com/nix-rust/nix/pull/1473)) - Added `setrlimit` and `getrlimit`. (#[1302](https://github.com/nix-rust/nix/pull/1302)) - Added `ptrace::interrupt` method for platforms that support `PTRACE_INTERRUPT` (#[1422](https://github.com/nix-rust/nix/pull/1422)) - Added `IP6T_SO_ORIGINAL_DST` sockopt. (#[1490](https://github.com/nix-rust/nix/pull/1490)) ### Changed - `FdSet::{contains, highest, fds}` no longer require a mutable reference. (#[1464](https://github.com/nix-rust/nix/pull/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](https://github.com/nix-rust/nix/pull/1471)) - `eventfd`s are supported on Android, change conditional compilation to include `sys::eventfd::eventfd` and `sys::eventfd::EfdFlags`for Android builds. (#[1481](https://github.com/nix-rust/nix/pull/1481)) - Most enums that come from C, for example `Errno`, are now marked as `#[non_exhaustive]`. (#[1474](https://github.com/nix-rust/nix/pull/1474)) - Many more functions, mostly contructors, are now `const`. (#[1476](https://github.com/nix-rust/nix/pull/1476)) (#[1492](https://github.com/nix-rust/nix/pull/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](https://github.com/nix-rust/nix/pull/1484)) - Minimum supported Rust version is now 1.46.0. ([#1492](https://github.com/nix-rust/nix/pull/1492)) ### Fixed - Added more errno definitions for better backwards compatibility with Nix 0.21.0. (#[1467](https://github.com/nix-rust/nix/pull/1467)) - Fixed potential undefined behavior in `Signal::try_from` on some platforms. (#[1484](https://github.com/nix-rust/nix/pull/1484)) ### Removed - Removed a couple of termios constants on redox that were never actually supported. (#[1483](https://github.com/nix-rust/nix/pull/1483)) - Removed `nix::sys::signal::NSIG`. It was of dubious utility, and not correct for all platforms. (#[1484](https://github.com/nix-rust/nix/pull/1484)) - Removed support for 32-bit Apple targets, since they've been dropped by both Rustc and Xcode. (#[1492](https://github.com/nix-rust/nix/pull/1492)) ## [0.22.0] - 9 July 2021 ### Added - Added `if_nameindex` (#[1445](https://github.com/nix-rust/nix/pull/1445)) - Added `nmount` for FreeBSD. (#[1453](https://github.com/nix-rust/nix/pull/1453)) - Added `IpFreebind` socket option (sockopt) on Linux, Fuchsia and Android. (#[1456](https://github.com/nix-rust/nix/pull/1456)) - Added `TcpUserTimeout` socket option (sockopt) on Linux and Fuchsia. (#[1457](https://github.com/nix-rust/nix/pull/1457)) - Added `renameat2` for Linux (#[1458](https://github.com/nix-rust/nix/pull/1458)) - Added `RxqOvfl` support on Linux, Fuchsia and Android. (#[1455](https://github.com/nix-rust/nix/pull/1455)) ### Changed - `ptsname_r` now returns a lossily-converted string in the event of bad UTF, just like `ptsname`. ([#1446](https://github.com/nix-rust/nix/pull/1446)) - Nix's error type is now a simple wrapper around the platform's Errno. This means it is now `Into`. 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](https://github.com/nix-rust/nix/pull/1446)) ### Fixed ### Removed ## [0.21.0] - 31 May 2021 ### Added - Added `getresuid` and `getresgid` (#[1430](https://github.com/nix-rust/nix/pull/1430)) - Added TIMESTAMPNS support for linux (#[1402](https://github.com/nix-rust/nix/pull/1402)) - Added `sendfile64` (#[1439](https://github.com/nix-rust/nix/pull/1439)) - Added `MS_LAZYTIME` to `MsFlags` (#[1437](https://github.com/nix-rust/nix/pull/1437)) ### Changed - Made `forkpty` unsafe, like `fork` (#[1390](https://github.com/nix-rust/nix/pull/1390)) - Made `Uid`, `Gid` and `Pid` methods `from_raw` and `as_raw` a `const fn` (#[1429](https://github.com/nix-rust/nix/pull/1429)) - Made `Uid::is_root` a `const fn` (#[1429](https://github.com/nix-rust/nix/pull/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](https://github.com/nix-rust/nix/pull/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](https://github.com/nix-rust/nix/pull/1440)) - Minimum supported Rust version is now 1.41.0. ([#1440](https://github.com/nix-rust/nix/pull/1440)) - Errno aliases are now associated consts on `Errno`, instead of consts in the `errno` module. (#[1452](https://github.com/nix-rust/nix/pull/1452)) ### Fixed - Allow `sockaddr_ll` size, as reported by the Linux kernel, to be smaller then it's definition (#[1395](https://github.com/nix-rust/nix/pull/1395)) - Fix spurious errors using `sendmmsg` with multiple cmsgs (#[1414](https://github.com/nix-rust/nix/pull/1414)) - Added `Errno::EOPNOTSUPP` to FreeBSD, where it was missing. (#[1452](https://github.com/nix-rust/nix/pull/1452)) ### Removed - Removed `sys::socket::accept4` from Android arm because libc removed it in version 0.2.87. ([#1399](https://github.com/nix-rust/nix/pull/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. `AioCb`s now work exclusively with borrowed buffers, not owned ones. (#[1440](https://github.com/nix-rust/nix/pull/1440)) - Removed some Errno values from platforms where they aren't actually defined. (#[1452](https://github.com/nix-rust/nix/pull/1452)) ## [0.20.0] - 20 February 2021 ### Added - Added a `passwd` field to `Group` (#[1338](https://github.com/nix-rust/nix/pull/1338)) - Added `mremap` (#[1306](https://github.com/nix-rust/nix/pull/1306)) - Added `personality` (#[1331](https://github.com/nix-rust/nix/pull/1331)) - Added limited Fuchsia support (#[1285](https://github.com/nix-rust/nix/pull/1285)) - Added `getpeereid` (#[1342](https://github.com/nix-rust/nix/pull/1342)) - Implemented `IntoIterator` for `Dir` (#[1333](https://github.com/nix-rust/nix/pull/1333)). ### Changed - Minimum supported Rust version is now 1.40.0. ([#1356](https://github.com/nix-rust/nix/pull/1356)) - i686-apple-darwin has been demoted to Tier 2 support, because it's deprecated by Xcode. (#[1350](https://github.com/nix-rust/nix/pull/1350)) - Fixed calling `recvfrom` on an `AddrFamily::Packet` socket (#[1344](https://github.com/nix-rust/nix/pull/1344)) ### Fixed - `TimerFd` now closes the underlying fd on drop. ([#1381](https://github.com/nix-rust/nix/pull/1381)) - Define `*_MAGIC` filesystem constants on Linux s390x (#[1372](https://github.com/nix-rust/nix/pull/1372)) - mqueue, sysinfo, timespec, statfs, test_ptrace_syscall() on x32 (#[1366](https://github.com/nix-rust/nix/pull/1366)) ### Removed - `Dir`, `SignalFd`, and `PtyMaster` are no longer `Clone`. (#[1382](https://github.com/nix-rust/nix/pull/1382)) - Removed `SockLevel`, which hasn't been used for a few years (#[1362](https://github.com/nix-rust/nix/pull/1362)) - Removed both `Copy` and `Clone` from `TimerFd`.

(#[1281](https://github.com/nix-rust/nix/pull/1281)) - Added wrapper functions for `PTRACE_SYSEMU` and `PTRACE_SYSEMU_SINGLESTEP`. (#[1300](https://github.com/nix-rust/nix/pull/1300)) - Add support for Vsock on Android rather than just Linux. (#[1301](https://github.com/nix-rust/nix/pull/1301)) - Added `TCP_KEEPCNT` and `TCP_KEEPINTVL` TCP keepalive options. (#[1283](https://github.com/nix-rust/nix/pull/1283)) ### Changed - Expose `SeekData` and `SeekHole` on all Linux targets (#[1284](https://github.com/nix-rust/nix/pull/1284)) - Changed unistd::{execv,execve,execvp,execvpe,fexecve,execveat} to take both `&[&CStr]` and `&[CString]` as its list argument(s). (#[1278](https://github.com/nix-rust/nix/pull/1278)) - Made `unistd::fork` an unsafe funtion, bringing it in line with [libstd's decision](https://github.com/rust-lang/rust/pull/58059). (#[1293](https://github.com/nix-rust/nix/pull/1293)) ### Fixed ### Removed ## [0.18.0] - 26 July 2020 ### Added - Added `fchown(2)` wrapper.

(#[1211](https://github.com/nix-rust/nix/pull/1211)) - Added support for `F_OFD_*` `fcntl` commands on Linux and Android. (#[1195](https://github.com/nix-rust/nix/pull/1195)) - Added `env::clearenv()`: calls `libc::clearenv` on platforms where it's available, and clears the environment of all variables via `std::env::vars` and `std::env::remove_var` on others. (#[1185](https://github.com/nix-rust/nix/pull/1185)) - `FsType` inner value made public. (#[1187](https://github.com/nix-rust/nix/pull/1187)) - Added `unistd::setfsuid` and `unistd::setfsgid` to set the user or group identity for filesystem checks per-thread. (#[1163](https://github.com/nix-rust/nix/pull/1163)) - Derived `Ord`, `PartialOrd` for `unistd::Pid` (#[1189](https://github.com/nix-rust/nix/pull/1189)) - Added `select::FdSet::fds` method to iterate over file descriptors in a set. ([#1207](https://github.com/nix-rust/nix/pull/1207)) - Added support for UDP generic segmentation offload (GSO) and generic receive offload (GRO) ([#1209](https://github.com/nix-rust/nix/pull/1209)) - Added support for `sendmmsg` and `recvmmsg` calls (#[1208](https://github.com/nix-rust/nix/pull/1208)) - Added support for `SCM_CREDS` messages (`UnixCredentials`) on FreeBSD/DragonFly (#[1216](https://github.com/nix-rust/nix/pull/1216)) - Added `BindToDevice` socket option (sockopt) on Linux (#[1233](https://github.com/nix-rust/nix/pull/1233)) - Added `EventFilter` bitflags for `EV_DISPATCH` and `EV_RECEIPT` on OpenBSD.

(#[1222](https://github.com/nix-rust/nix/pull/1222)) - `CpuSet` and `UnixCredentials` now implement `Default`. (#[1244](https://github.com/nix-rust/nix/pull/1244)) - Added `unistd::ttyname` (#[1259](https://github.com/nix-rust/nix/pull/1259)) - Added support for `Ipv4PacketInfo` and `Ipv6PacketInfo` to `ControlMessage` for iOS and Android.

(#[1261](https://github.com/nix-rust/nix/pull/1261)) ### Changed - Changed `fallocate` return type from `c_int` to `()` (#[1201](https://github.com/nix-rust/nix/pull/1201)) - Enabled `sys::ptrace::setregs` and `sys::ptrace::getregs` on x86_64-unknown-linux-musl target (#[1198](https://github.com/nix-rust/nix/pull/1198)) - On Linux, `ptrace::write` is now an `unsafe` function. Caveat programmer. (#[1245](https://github.com/nix-rust/nix/pull/1245)) - `execv`, `execve`, `execvp` and `execveat` in `::nix::unistd` and `reboot` in `::nix::sys::reboot` now return `Result` instead of `Result` (#[1239](https://github.com/nix-rust/nix/pull/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](https://github.com/nix-rust/nix/pull/1244)) - Several `Inotify` methods now take `self` by value instead of by reference (#[1244](https://github.com/nix-rust/nix/pull/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](https://github.com/nix-rust/nix/pull/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](https://github.com/nix-rust/nix/pull/1198)) - Fixed unaligned casting of `cmsg_data` to `af_alg_iv` (#[1206](https://github.com/nix-rust/nix/pull/1206)) - Fixed `readlink`/`readlinkat` when reading symlinks longer than `PATH_MAX` (#[1231](https://github.com/nix-rust/nix/pull/1231)) - `PollFd`, `EpollEvent`, `IpMembershipRequest`, `Ipv6MembershipRequest`, `TimeVal`, and `IoVec` are now `repr(transparent)`. This is required for correctness's sake across all architectures and compilers, though now bugs have been reported so far. (#[1243](https://github.com/nix-rust/nix/pull/1243)) - Fixed unaligned pointer read in `Inotify::read_events`. (#[1244](https://github.com/nix-rust/nix/pull/1244)) ### Removed - Removed `sys::socket::addr::from_libc_sockaddr` from the public API. (#[1215](https://github.com/nix-rust/nix/pull/1215)) - Removed `sys::termios::{get_libc_termios, get_libc_termios_mut, update_wrapper` from the public API. These were previously hidden in the docs but still usable by downstream. (#[1235](https://github.com/nix-rust/nix/pull/1235)) - Nix no longer implements `NixPath` for `Option

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](https://github.com/nix-rust/nix/pull/1242)) - Removed `unistd::daemon` and `unistd::pipe2` on OSX and ios (#[1255](https://github.com/nix-rust/nix/pull/1255)) - Removed `sys::event::FilterFlag::NOTE_EXIT_REPARENTED` and `sys::event::FilterFlag::NOTE_REAP` on OSX and ios.

([#1148](https://github.com/nix-rust/nix/pull/1148)) - Added optional `Signal` argument to `ptrace::{detach, syscall}` for signal injection. ([#1083](https://github.com/nix-rust/nix/pull/1083)) ### Changed - `sys::termios::BaudRate` now implements `TryFrom` instead of `From`. The old `From` implementation would panic on failure. ([#1159](https://github.com/nix-rust/nix/pull/1159)) - `sys::socket::ControlMessage::ScmCredentials` and `sys::socket::ControlMessageOwned::ScmCredentials` now wrap `UnixCredentials` rather than `libc::ucred`. ([#1160](https://github.com/nix-rust/nix/pull/1160)) - `sys::socket::recvmsg` now takes a plain `Vec` instead of a `CmsgBuffer` implementor. If you were already using `cmsg_space!`, then you needn't worry. ([#1156](https://github.com/nix-rust/nix/pull/1156)) - `sys::socket::recvfrom` now returns `Result<(usize, Option)>` instead of `Result<(usize, SockAddr)>`. ([#1145](https://github.com/nix-rust/nix/pull/1145)) - `Signal::from_c_int` has been replaced by `Signal::try_from` ([#1113](https://github.com/nix-rust/nix/pull/1113)) - Changed `readlink` and `readlinkat` to return `OsString` ([#1109](https://github.com/nix-rust/nix/pull/1109)) ```rust # use nix::fcntl::{readlink, readlinkat}; // the buffer argument of `readlink` and `readlinkat` has been removed, // and the return value is now an owned type (`OsString`). // Existing code can be updated by removing the buffer argument // and removing any clone or similar operation on the output // old code `readlink(&path, &mut buf)` can be replaced with the following let _: OsString = readlink(&path); // old code `readlinkat(dirfd, &path, &mut buf)` can be replaced with the following let _: OsString = readlinkat(dirfd, &path); ``` - Minimum supported Rust version is now 1.36.0. ([#1108](https://github.com/nix-rust/nix/pull/1108)) - `Ipv4Addr::octets`, `Ipv4Addr::to_std`, `Error::as_errno`, `ForkResult::is_child`, `ForkResult::is_parent`, `Gid::as_raw`, `Uid::is_root`, `Uid::as_raw`, `Pid::as_raw`, and `PollFd::revents` now take `self` by value. ([#1107](https://github.com/nix-rust/nix/pull/1107)) - Type `&CString` for parameters of `exec(v|ve|vp|vpe|veat)` are changed to `&CStr`.

([#1091](https://github.com/nix-rust/nix/pull/1091)) - Add `unlinkat` ([#1058](https://github.com/nix-rust/nix/pull/1058)) - Add `renameat`. ([#1097](https://github.com/nix-rust/nix/pull/1097)) ### Changed - Support for `ifaddrs` now present when building for Android. ([#1077](https://github.com/nix-rust/nix/pull/1077)) - Minimum supported Rust version is now 1.31.0 ([#1035](https://github.com/nix-rust/nix/pull/1035)) ([#1095](https://github.com/nix-rust/nix/pull/1095)) - Now functions `statfs()` and `fstatfs()` return result with `Statfs` wrapper ([#928](https://github.com/nix-rust/nix/pull/928)) ### Fixed - Enabled `sched_yield` for all nix hosts.

([#820](https://github.com/nix-rust/nix/pull/820)) - The syscall module has been removed. This only exposed enough functionality for `memfd_create()` and `pivot_root()`, which are still exposed as separate functions. ([#747](https://github.com/nix-rust/nix/pull/747)) - The `Errno` variants are no longer reexported from the `errno` module. `Errno` itself is no longer reexported from the crate root and instead must be accessed using the `errno` module. ([#696](https://github.com/nix-rust/nix/pull/696)) - Removed `MS_VERBOSE`, `MS_NOSEC`, and `MS_BORN` from `MsFlags`. These are internal kernel flags and should never have been exposed.

([#661](https://github.com/nix-rust/nix/pull/661)) - Changed `ioctl!(write ...)` into `ioctl!(write_ptr ...)` and `ioctl!(write_int ..)` variants to more clearly separate those use cases. ([#670](https://github.com/nix-rust/nix/pull/670)) - Marked `sys::mman::{ mmap, munmap, madvise, munlock, msync }` as unsafe. ([#559](https://github.com/nix-rust/nix/pull/559)) - Minimum supported Rust version is now 1.13. - Removed `revents` argument from `PollFd::new()` as it's an output argument and will be overwritten regardless of value. ([#542](https://github.com/nix-rust/nix/pull/542)) - Changed type signature of `sys::select::FdSet::contains` to make `self` immutable ([#564](https://github.com/nix-rust/nix/pull/564)) - Introduced wrapper types for `gid_t`, `pid_t`, and `uid_t` as `Gid`, `Pid`, and `Uid` respectively. Various functions have been changed to use these new types as arguments. ([#629](https://github.com/nix-rust/nix/pull/629)) - Fixed compilation on all Android and iOS targets ([#527](https://github.com/nix-rust/nix/pull/527)) and promoted them to Tier 2 support. - `nix::sys::statfs::{statfs,fstatfs}` uses statfs definition from `libc::statfs` instead of own linux specific type `nix::sys::Statfs`.

([#561](https://github.com/nix-rust/nix/pull/561)) - Revised the termios API including additional tests and documentation and exposed it on iOS. ([#527](https://github.com/nix-rust/nix/pull/527)) - `eventfd`, `signalfd`, and `pwritev`/`preadv` functionality is now included by default for all supported platforms. ([#681](https://github.com/nix-rust/nix/pull/561)) - The `ioctl!` macro's plain variants has been replaced with "bad read" to be consistent with other variants. The generated functions also have more strict types for their arguments. The "*_buf" variants also now calculate total array size and take slice references for improved type safety. The documentation has also been dramatically improved. ([#670](https://github.com/nix-rust/nix/pull/670)) ### Removed - Removed `io::Error` from `nix::Error` and the conversion from `nix::Error` to `Errno` ([#614](https://github.com/nix-rust/nix/pull/614)) - All feature flags have been removed in favor of conditional compilation on supported platforms. `execvpe` is no longer supported, but this was already broken and will be added back in the next release. ([#681](https://github.com/nix-rust/nix/pull/561)) - Removed `ioc_*` functions and many helper constants and macros within the `ioctl` module. These should always have been private and only the `ioctl!` should be used in public code. ([#670](https://github.com/nix-rust/nix/pull/670)) ### Fixed - Fixed multiple issues compiling under different archetectures and OSes. Now compiles on Linux/MIPS ([#538](https://github.com/nix-rust/nix/pull/538)), `Linux/PPC` ([#553](https://github.com/nix-rust/nix/pull/553)), `MacOS/x86_64,i686` ([#553](https://github.com/nix-rust/nix/pull/553)), `NetBSD/x64_64` ([#538](https://github.com/nix-rust/nix/pull/538)), `FreeBSD/x86_64,i686` ([#536](https://github.com/nix-rust/nix/pull/536)), and `Android` ([#631](https://github.com/nix-rust/nix/pull/631)). - `bind` and `errno_location` now work correctly on `Android` ([#631](https://github.com/nix-rust/nix/pull/631)) - Added `nix::ptrace` on all Linux-kernel-based platforms [#624](https://github.com/nix-rust/nix/pull/624).

([#623](https://github.com/nix-rust/nix/pull/623)) - Multiple constants related to the termios API have now been properly defined for all supported platforms. ([#527](https://github.com/nix-rust/nix/pull/527)) - `ioctl!` macro now supports working with non-int datatypes and properly supports all platforms. ([#670](https://github.com/nix-rust/nix/pull/670)) ## [0.8.1] 2017-04-16 ### Fixed - Fixed build on FreeBSD. (Cherry-picked [a859ee3c](https://github.com/nix-rust/nix/commit/a859ee3c9396dfdb118fcc2c8ecc697e2d303467)) ## [0.8.0] 2017-03-02 ### Added - Added `::nix::sys::termios::BaudRate` enum to provide portable baudrate values. ([#518](https://github.com/nix-rust/nix/pull/518)) - Added a new `WaitStatus::PtraceEvent` to support ptrace events on Linux and Android ([#438](https://github.com/nix-rust/nix/pull/438)) - Added support for POSIX AIO ([#483](https://github.com/nix-rust/nix/pull/483)) ([#506](https://github.com/nix-rust/nix/pull/506)) - Added support for XNU system control sockets ([#478](https://github.com/nix-rust/nix/pull/478)) - Added support for `ioctl` calls on BSD platforms ([#478](https://github.com/nix-rust/nix/pull/478)) - Added struct `TimeSpec` ([#475](https://github.com/nix-rust/nix/pull/475)) ([#483](https://github.com/nix-rust/nix/pull/483)) - Added complete definitions for all kqueue-related constants on all supported OSes ([#415](https://github.com/nix-rust/nix/pull/415)) - Added function `epoll_create1` and bitflags `EpollCreateFlags` in `::nix::sys::epoll` in order to support `::libc::epoll_create1`. ([#410](https://github.com/nix-rust/nix/pull/410)) - Added `setresuid` and `setresgid` for Linux in `::nix::unistd` ([#448](https://github.com/nix-rust/nix/pull/448)) - Added `getpgid` in `::nix::unistd` ([#433](https://github.com/nix-rust/nix/pull/433)) - Added `tcgetpgrp` and `tcsetpgrp` in `::nix::unistd` ([#451](https://github.com/nix-rust/nix/pull/451)) - Added `CLONE_NEWCGROUP` in `::nix::sched` ([#457](https://github.com/nix-rust/nix/pull/457)) - Added `getpgrp` in `::nix::unistd` ([#491](https://github.com/nix-rust/nix/pull/491)) - Added `fchdir` in `::nix::unistd` ([#497](https://github.com/nix-rust/nix/pull/497)) - Added `major` and `minor` in `::nix::sys::stat` for decomposing `dev_t` ([#508](https://github.com/nix-rust/nix/pull/508)) - Fixed the style of many bitflags and use `libc` in more places. ([#503](https://github.com/nix-rust/nix/pull/503)) - Added `ppoll` in `::nix::poll` ([#520](https://github.com/nix-rust/nix/pull/520)) - Added support for getting and setting pipe size with fcntl(2) on Linux ([#540](https://github.com/nix-rust/nix/pull/540)) ### Changed - `::nix::sys::termios::{cfgetispeed, cfsetispeed, cfgetospeed, cfsetospeed}` switched to use `BaudRate` enum from `speed_t`. ([#518](https://github.com/nix-rust/nix/pull/518)) - `epoll_ctl` now could accept None as argument `event` when op is `EpollOp::EpollCtlDel`. ([#480](https://github.com/nix-rust/nix/pull/480)) - Removed the `bad` keyword from the `ioctl!` macro ([#478](https://github.com/nix-rust/nix/pull/478)) - Changed `TimeVal` into an opaque Newtype ([#475](https://github.com/nix-rust/nix/pull/475)) - `kill`'s signature, defined in `::nix::sys::signal`, changed, so that the signal parameter has type `T: Into>`. `None` as an argument for that parameter will result in a 0 passed to libc's `kill`, while a `Some`-argument will result in the previous behavior for the contained `Signal`. ([#445](https://github.com/nix-rust/nix/pull/445)) - The minimum supported version of rustc is now 1.7.0. ([#444](https://github.com/nix-rust/nix/pull/444)) - Changed `KEvent` to an opaque structure that may only be modified by its constructor and the `ev_set` method. ([#415](https://github.com/nix-rust/nix/pull/415)) ([#442](https://github.com/nix-rust/nix/pull/442)) ([#463](https://github.com/nix-rust/nix/pull/463)) - `pipe2` now calls `libc::pipe2` where available. Previously it was emulated using `pipe`, which meant that setting `O_CLOEXEC` was not atomic. ([#427](https://github.com/nix-rust/nix/pull/427)) - Renamed `EpollEventKind` to `EpollFlags` in `::nix::sys::epoll` in order for it to conform with our conventions. ([#410](https://github.com/nix-rust/nix/pull/410)) - `EpollEvent` in `::nix::sys::epoll` is now an opaque proxy for `::libc::epoll_event`. The formerly public field `events` is now be read-only accessible with the new method `events()` of `EpollEvent`. Instances of `EpollEvent` can be constructed using the new method `new()` of EpollEvent. ([#410](https://github.com/nix-rust/nix/pull/410)) - `SigFlags` in `::nix::sys::signal` has be renamed to `SigmaskHow` and its type has changed from `bitflags` to `enum` in order to conform to our conventions. ([#460](https://github.com/nix-rust/nix/pull/460)) - `sethostname` now takes a `&str` instead of a `&[u8]` as this provides an API that makes more sense in normal, correct usage of the API. - `gethostname` previously did not expose the actual length of the hostname written from the underlying system call at all. This has been updated to return a `&CStr` within the provided buffer that is always properly NUL-terminated (this is not guaranteed by the call with all platforms/libc implementations). - Exposed all fcntl(2) operations at the module level, so they can be imported direclty instead of via `FcntlArg` enum. ([#541](https://github.com/nix-rust/nix/pull/541)) ### Fixed - Fixed multiple issues with Unix domain sockets on non-Linux OSes ([#474](https://github.com/nix-rust/nix/pull/415)) - Fixed using kqueue with `EVFILT_USER` on FreeBSD ([#415](https://github.com/nix-rust/nix/pull/415)) - Fixed the build on FreeBSD, and fixed the getsockopt, sendmsg, and recvmsg functions on that same OS. ([#397](https://github.com/nix-rust/nix/pull/397)) - Fixed an off-by-one bug in `UnixAddr::new_abstract` in `::nix::sys::socket`. ([#429](https://github.com/nix-rust/nix/pull/429)) - Fixed clone passing a potentially unaligned stack. ([#490](https://github.com/nix-rust/nix/pull/490)) - Fixed mkdev not creating a `dev_t` the same way as libc. ([#508](https://github.com/nix-rust/nix/pull/508)) ## [0.7.0] 2016-09-09 ### Added - Added `lseek` and `lseek64` in `::nix::unistd` ([#377](https://github.com/nix-rust/nix/pull/377)) - Added `mkdir` and `getcwd` in `::nix::unistd` ([#416](https://github.com/nix-rust/nix/pull/416)) - Added accessors `sigmask_mut` and `sigmask` to `UContext` in `::nix::ucontext`. ([#370](https://github.com/nix-rust/nix/pull/370)) - Added `WUNTRACED` to `WaitPidFlag` in `::nix::sys::wait` for non-_linux_ targets. ([#379](https://github.com/nix-rust/nix/pull/379)) - Added new module `::nix::sys::reboot` with enumeration `RebootMode` and functions `reboot` and `set_cad_enabled`. Currently for _linux_ only. ([#386](https://github.com/nix-rust/nix/pull/386)) - `FdSet` in `::nix::sys::select` now also implements `Clone`. ([#405](https://github.com/nix-rust/nix/pull/405)) - Added `F_FULLFSYNC` to `FcntlArg` in `::nix::fcntl` for _apple_ targets. ([#407](https://github.com/nix-rust/nix/pull/407)) - Added `CpuSet::unset` in `::nix::sched`. ([#402](https://github.com/nix-rust/nix/pull/402)) - Added constructor method `new()` to `PollFd` in `::nix::poll`, in order to allow creation of objects, after removing public access to members. ([#399](https://github.com/nix-rust/nix/pull/399)) - Added method `revents()` to `PollFd` in `::nix::poll`, in order to provide read access to formerly public member `revents`. ([#399](https://github.com/nix-rust/nix/pull/399)) - Added `MSG_CMSG_CLOEXEC` to `MsgFlags` in `::nix::sys::socket` for _linux_ only. ([#422](https://github.com/nix-rust/nix/pull/422)) ### Changed - Replaced the reexported integer constants for signals by the enumeration `Signal` in `::nix::sys::signal`. ([#362](https://github.com/nix-rust/nix/pull/362)) - Renamed `EventFdFlag` to `EfdFlags` in `::nix::sys::eventfd`. ([#383](https://github.com/nix-rust/nix/pull/383)) - Changed the result types of `CpuSet::is_set` and `CpuSet::set` in `::nix::sched` to `Result` and `Result<()>`, respectively. They now return `EINVAL`, if an invalid argument for the `field` parameter is passed. ([#402](https://github.com/nix-rust/nix/pull/402)) - `MqAttr` in `::nix::mqueue` is now an opaque proxy for `::libc::mq_attr`, which has the same structure as the old `MqAttr`. The field `mq_flags` of `::libc::mq_attr` is readable using the new method `flags()` of `MqAttr`. `MqAttr` also no longer implements `Debug`. ([#392](https://github.com/nix-rust/nix/pull/392)) - The parameter `msq_prio` of `mq_receive` with type `u32` in `::nix::mqueue` was replaced by a parameter named `msg_prio` with type `&mut u32`, so that the message priority can be obtained by the caller. ([#392](https://github.com/nix-rust/nix/pull/392)) - The type alias `MQd` in `::nix::queue` was replaced by the type alias `libc::mqd_t`, both of which are aliases for the same type. ([#392](https://github.com/nix-rust/nix/pull/392)) ### Removed - Type alias `SigNum` from `::nix::sys::signal`. ([#362](https://github.com/nix-rust/nix/pull/362)) - Type alias `CpuMask` from `::nix::shed`. ([#402](https://github.com/nix-rust/nix/pull/402)) - Removed public fields from `PollFd` in `::nix::poll`. (See also added method `revents()`. ([#399](https://github.com/nix-rust/nix/pull/399)) ### Fixed - Fixed the build problem for NetBSD (Note, that we currently do not support it, so it might already be broken again). ([#389](https://github.com/nix-rust/nix/pull/389)) - Fixed the build on FreeBSD, and fixed the getsockopt, sendmsg, and recvmsg functions on that same OS. ([#397](https://github.com/nix-rust/nix/pull/397)) ## [0.6.0] 2016-06-10 ### Added - Added `gettid` in `::nix::unistd` for _linux_ and _android_. ([#293](https://github.com/nix-rust/nix/pull/293)) - Some _mips_ support in `::nix::sched` and `::nix::sys::syscall`. ([#301](https://github.com/nix-rust/nix/pull/301)) - Added `SIGNALFD_SIGINFO_SIZE` in `::nix::sys::signalfd`. ([#309](https://github.com/nix-rust/nix/pull/309)) - Added new module `::nix::ucontext` with struct `UContext`. Currently for _linux_ only.

([#359](https://github.com/nix-rust/nix/pull/359)) - Added `clear` and `extend` functions to `SigSet`'s implementation in `::nix::sys::signal`. ([#347](https://github.com/nix-rust/nix/pull/347)) - `sockaddr_storage_to_addr` in `::nix::sys::socket` now supports `sockaddr_nl` on _linux_ and _android_. ([#366](https://github.com/nix-rust/nix/pull/366)) - Added support for `SO_ORIGINAL_DST` in `::nix::sys::socket` on _linux_. ([#367](https://github.com/nix-rust/nix/pull/367)) - Added `SIGINFO` in `::nix::sys::signal` for the _macos_ target as well as `SIGPWR` and `SIGSTKFLT` in `::nix::sys::signal` for non-_macos_ targets. ([#361](https://github.com/nix-rust/nix/pull/361)) ### Changed - Changed the structure `IoVec` in `::nix::sys::uio`. ([#304](https://github.com/nix-rust/nix/pull/304)) - Replaced `CREATE_NEW_FD` by `SIGNALFD_NEW` in `::nix::sys::signalfd`. ([#309](https://github.com/nix-rust/nix/pull/309)) - Renamed `SaFlag` to `SaFlags` and `SigFlag` to `SigFlags` in `::nix::sys::signal`.

([#344](https://github.com/nix-rust/nix/pull/344)) - `execv`, `execve`, and `execvp` now return `Result` instead of `Result<()>` in `::nix::unistd`. ([#357](https://github.com/nix-rust/nix/pull/357)) ### Fixed - Improved the conversion from `std::net::SocketAddr` to `InetAddr` in `::nix::sys::socket::addr`. ([#335](https://github.com/nix-rust/nix/pull/335)) ## [0.5.0] 2016-03-01
