`SysControlAddr`, `LinkAddr`, and `VsockAddr`.
(#[1614](https://github.com/nix-rust/nix/pull/1614))
- Removed `EventFlag::EV_SYSFLAG`.
(#[1635](https://github.com/nix-rust/nix/pull/1635))
## [0.23.1] - 2021-12-16
### 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](https://github.com/nix-rust/nix/pull/1607))
### Fixed
- Fixed soundness issues in `FdSet::insert`, `FdSet::remove`, and
`FdSet::contains` involving file descriptors outside of the range

(#[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))
- Rework `UnixAddr` to encapsulate internals better in order to fix soundness
issues. No longer allows creating a `UnixAddr` from a raw `sockaddr_un`.
([#1496](https://github.com/nix-rust/nix/pull/1496))
- Raised bitflags to 1.3.0 and the MSRV to 1.46.0.
([#1492](https://github.com/nix-rust/nix/pull/1492))
### Fixed
- `posix_fadvise` now returns errors in the conventional way, rather than as a
non-zero value in `Ok()`.
(#[1538](https://github.com/nix-rust/nix/pull/1538))
- 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))

(#[1545](https://github.com/nix-rust/nix/pull/1545))
### 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))

(#[1511](https://github.com/nix-rust/nix/pull/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](https://github.com/nix-rust/nix/pull/1607))
## [0.22.2] - 28 September 2021
### Fixed
- Fixed buffer overflow in `unistd::getgrouplist`.
(#[1545](https://github.com/nix-rust/nix/pull/1545))
- Added more errno definitions for better backwards compatibility with
Nix 0.21.0.
(#[1467](https://github.com/nix-rust/nix/pull/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](https://github.com/nix-rust/nix/pull/1483))

### 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<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](https://github.com/nix-rust/nix/pull/1446))
## [0.21.2] - 29 September 2021

(#[1483](https://github.com/nix-rust/nix/pull/1483))
## [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))
## [0.20.2] - 28 September 2021
### Fixed

- 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))

by Xcode.
(#[1350](https://github.com/nix-rust/nix/pull/1350))

([#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`.
([#1381](https://github.com/nix-rust/nix/pull/1381))
## [0.19.1] - 28 November 2020
### Fixed

(#[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))
## [0.18.0] - 26 July 2020

- Added support for `F_OFD_*` `fcntl` commands on Linux and Android.
(#[1195](https://github.com/nix-rust/nix/pull/1195))

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 support for `TimerFd`.
(#[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<Infallible>` instead of `Result<Void>` (#[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<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](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))

### Added
- Add `CLK_TCK` to `SysconfVar`
(#[1177](https://github.com/nix-rust/nix/pull/1177))
### Removed
- Removed deprecated Error::description from error types
(#[1175](https://github.com/nix-rust/nix/pull/1175))
## [0.16.1] - 23 December 2019
### Fixed
- Fixed the build for OpenBSD
(#[1168](https://github.com/nix-rust/nix/pull/1168))
## [0.16.0] - 1 December 2019
### Added
- Added `ptrace::seize()`: similar to `attach()` on Linux
but with better-defined semantics.
(#[1154](https://github.com/nix-rust/nix/pull/1154))
- Added `Signal::as_str()`: returns signal name as `&'static str`
(#[1138](https://github.com/nix-rust/nix/pull/1138))
- Added `posix_fallocate`.
([#1105](https://github.com/nix-rust/nix/pull/1105))
- Implemented `Default` for `FdSet`
([#1107](https://github.com/nix-rust/nix/pull/1107))

`Group::from_name`,
([#1139](https://github.com/nix-rust/nix/pull/1139))
- Added `linkat`
([#1101](https://github.com/nix-rust/nix/pull/1101))
- Added `sched_getaffinity`.
([#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<speed_t>` instead of
`From<speed_t>`. 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<SockAddr>)>` 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`.
([#1121](https://github.com/nix-rust/nix/pull/1121))
### Fixed
- Fix length of abstract socket addresses
([#1120](https://github.com/nix-rust/nix/pull/1120))

types that support them. ([#1035](https://github.com/nix-rust/nix/pull/1035))
- Added `copy_file_range` wrapper
([#1069](https://github.com/nix-rust/nix/pull/1069))
- Add `mkdirat`.
([#1084](https://github.com/nix-rust/nix/pull/1084))
- Add `posix_fadvise`.
([#1089](https://github.com/nix-rust/nix/pull/1089))

([#928](https://github.com/nix-rust/nix/pull/928))
### Fixed
- Enabled `sched_yield` for all nix hosts.
([#1090](https://github.com/nix-rust/nix/pull/1090))
## [0.14.1] - 2019-06-06
### Added
- Macros exported by `nix` may now be imported via `use` on the Rust 2018
edition without importing helper macros on Linux targets.
([#1066](https://github.com/nix-rust/nix/pull/1066))
For example, in Rust 2018, the `ioctl_read_bad!` macro can now be imported
without importing the `convert_ioctl_res!` macro.
```rust
use nix::ioctl_read_bad;
ioctl_read_bad!(tcgets, libc::TCGETS, libc::termios);
```
### Changed
- Changed some public types from reexports of libc types like `uint32_t` to the
native equivalents like `u32.`
([#1072](https://github.com/nix-rust/nix/pull/1072/commits))
### Fixed
- Fix the build on Android and Linux/mips with recent versions of libc.
([#1072](https://github.com/nix-rust/nix/pull/1072/commits))
## [0.14.0] - 2019-05-21
### Added

Android and Linux. ([#1016](https://github.com/nix-rust/nix/pull/1016))
- Add `ALG_SET_IV`, `ALG_SET_OP` and `ALG_SET_AEAD_ASSOCLEN` control messages and `AF_ALG`
socket types on Linux and Android ([#1031](https://github.com/nix-rust/nix/pull/1031))
- Add killpg
([#1034](https://github.com/nix-rust/nix/pull/1034))
- Added ENOTSUP errno support for Linux and Android.
([#969](https://github.com/nix-rust/nix/pull/969))
- Add several errno constants from OpenBSD 6.2
([#1036](https://github.com/nix-rust/nix/pull/1036))

([#1043](https://github.com/nix-rust/nix/pull/1043))
- Added `nix::unistd:seteuid` and `nix::unistd::setegid` for those platforms that do
not support `setresuid` nor `setresgid` respectively.

- `PollFd` event flags renamed to `PollFlags` ([#1024](https://github.com/nix-rust/nix/pull/1024/))
- `recvmsg` now returns an Iterator over `ControlMessageOwned` objects rather
than `ControlMessage` objects. This is sadly not backwards-compatible. Fix
code like this:
```rust
if let ControlMessage::ScmRights(&fds) = cmsg {
```
By replacing it with code like this:
```rust
if let ControlMessageOwned::ScmRights(fds) = cmsg {
```
([#1020](https://github.com/nix-rust/nix/pull/1020))
- Replaced `CmsgSpace` with the `cmsg_space` macro.
([#1020](https://github.com/nix-rust/nix/pull/1020))
### Fixed
- Fixed multiple bugs when using `sendmsg` and `recvmsg` with ancillary control messages
([#1020](https://github.com/nix-rust/nix/pull/1020))
- Macros exported by `nix` may now be imported via `use` on the Rust 2018
edition without importing helper macros for BSD targets.
([#1041](https://github.com/nix-rust/nix/pull/1041))
For example, in Rust 2018, the `ioctl_read_bad!` macro can now be imported
without importing the `convert_ioctl_res!` macro.
```rust
use nix::ioctl_read_bad;
ioctl_read_bad!(tcgets, libc::TCGETS, libc::termios);
```
### Removed
- `Daemon`, `NOTE_REAP`, and `NOTE_EXIT_REPARENTED` are now deprecated on OSX
