(#[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)) - Rework `UnixAddr` to encapsulate internals better in order to fix soundness issues.

(#[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)) - Deprecated `SockAddr/InetAddr::to_str` in favor of `ToString::to_string` (#[1495](https://github.com/nix-rust/nix/pull/1495)) - Removed `SigevNotify` on OpenBSD and Redox. (#[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`.

(#[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)) ## [0.21.2] - 29 September 2021 ### Fixed - Fixed buffer overflow in `unistd::getgrouplist`. (#[1545](https://github.com/nix-rust/nix/pull/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](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.

([#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.

([#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.

([#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.

([#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. ([#311](https://github.com/nix-rust/nix/pull/311)) - Added `EPOLLEXCLUSIVE` to `EpollEventKind` in `::nix::sys::epoll`.

([#351](https://github.com/nix-rust/nix/pull/351)) - Added `S_IFDIR`, `S_IFLNK`, `S_IFMT` to `SFlag` in `::nix::sys::stat`. ([#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`. ([#314](https://github.com/nix-rust/nix/pull/314)) - Renamed `Fork` to `ForkResult` and changed its fields in `::nix::unistd`. ([#332](https://github.com/nix-rust/nix/pull/332)) - Added the `signal` parameter to `clone`'s signature in `::nix::sched`. ([#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
