### Changed
- Change the `ForkptyResult` type to the following repr so that the
uninitialized
`master` field won't be accessed in the child process:
```rs
pub enum ForkptyResult {
Parent {
child: Pid,
master: OwnedFd,
},
Child,
}

done
with the `SignalFd` API even if other references to it exist.

- `nix::poll::ppoll`: `sigmask` parameter is now optional.
- Changed `gethostname` to return an owned `OsString`.
- `signal:SigSet` is now marked as `repr(transparent)`.
### Removed
- Removed support for resubmitting partially complete `lio_listio` operations.
It was too complicated, and didn't fit Nix's theme of zero-cost abstractions.
Instead, it can be reimplemented downstream.
## [0.24.2] - 2022-07-17
### Fixed
- Fixed buffer overflow in `nix::sys::socket::recvfrom`.
- Enabled `SockaddrStorage::{as_link_addr, as_link_addr_mut}` for Linux-like

### Changed
- `mqueue` functions now operate on a distinct type, `nix::mqueue::MqdT`.
Accessors take this type by reference, not by value.
- 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`.
- 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.
- Changed `getrlimit` and `setrlimit` to use `rlim_t` directly
instead of `Option<rlim_t>`.
- Deprecated `InetAddr` and `SockAddr` in favor of `SockaddrIn`, `SockaddrIn6`,
and `SockaddrStorage`.
- Deprecated `IpAddr`, `Ipv4Addr`, and `Ipv6Addr` in favor of their equivalents
from the standard library.
- `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`.
- Replaced `IoVec` with `IoSlice` and `IoSliceMut`, and replaced `IoVec::from_slice` with
### Fixed
- `InetAddr::from_std` now sets the `sin_len`/`sin6_len` fields on the BSDs.

### Removed
- Removed public access to the inner fields of `NetlinkAddr`, `AlgAddr`,
`SysControlAddr`, `LinkAddr`, and `VsockAddr`.
- Removed `EventFlag::EV_SYSFLAG`.
## [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.
### Fixed
- Fixed soundness issues in `FdSet::insert`, `FdSet::remove`, and
`FdSet::contains` involving file descriptors outside of the range
`0..FD_SETSIZE`.

into a `libc::passwd`. Consumes the `User` struct to give ownership over
the member pointers.

- Added `MAP_EXCL`, `MAP_ALIGNED_SUPER`, and `MAP_CONCEAL` mmap flags, and
exposed `MAP_ANONYMOUS` for all operating systems.
- Added read/write accessors for 'events' on `PollFd`.
### Changed
- `FdSet::{contains, highest, fds}` no longer require a mutable reference.
- `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
- `eventfd`s are supported on Android, change conditional compilation to
include `sys::eventfd::eventfd` and `sys::eventfd::EfdFlags`for Android
builds.
- Most enums that come from C, for example `Errno`, are now marked as
`#[non_exhaustive]`.
- Many more functions, mostly contructors, are now `const`.
- `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.
- Minimum supported Rust version is now 1.46.0.
- Rework `UnixAddr` to encapsulate internals better in order to fix soundness
issues. No longer allows creating a `UnixAddr` from a raw `sockaddr_un`.
- Raised bitflags to 1.3.0 and the MSRV to 1.46.0.
### Fixed
- `posix_fadvise` now returns errors in the conventional way, rather than as a
non-zero value in `Ok()`.
- Added more errno definitions for better backwards compatibility with
Nix 0.21.0.
- Fixed potential undefined behavior in `Signal::try_from` on some platforms.
- Fixed buffer overflow in `unistd::getgrouplist`.
### Removed
- Removed a couple of termios constants on redox that were never actually
supported.
- Removed `nix::sys::signal::NSIG`. It was of dubious utility, and not correct
for all platforms.
- Removed support for 32-bit Apple targets, since they've been dropped by both
Rustc and Xcode.
- Deprecated `SockAddr/InetAddr::to_str` in favor of `ToString::to_string`
- Removed `SigevNotify` on OpenBSD and Redox.
## [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.
## [0.22.2] - 28 September 2021
### Fixed
- Fixed buffer overflow in `unistd::getgrouplist`.
- Added more errno definitions for better backwards compatibility with
Nix 0.21.0.
## [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.
## [0.22.0] - 9 July 2021
### Added
- Added `nmount` for FreeBSD.
- Added `IpFreebind` socket option (sockopt) on Linux, Fuchsia and Android.
- Added `TcpUserTimeout` socket option (sockopt) on Linux and Fuchsia.
- Added `renameat2` for Linux
- Added `RxqOvfl` support on Linux, Fuchsia and Android.
### Changed
- `ptsname_r` now returns a lossily-converted string in the event of bad UTF,
just like `ptsname`.
- 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`.
## [0.21.2] - 29 September 2021
### Fixed
- Fixed buffer overflow in `unistd::getgrouplist`.
## [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.
## [0.21.0] - 31 May 2021
### Added
- Added `getresuid` and `getresgid`
- Added TIMESTAMPNS support for linux
- Added `MS_LAZYTIME` to `MsFlags`
### Changed
- Made `forkpty` unsafe, like `fork`
- Made `Uid`, `Gid` and `Pid` methods `from_raw` and `as_raw` a `const fn`
- Made `Uid::is_root` a `const fn`
- `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.
- `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.
- Minimum supported Rust version is now 1.41.0.
- Errno aliases are now associated consts on `Errno`, instead of consts in the
`errno` module.
### Fixed
- Allow `sockaddr_ll` size, as reported by the Linux kernel, to be smaller then it's definition
- Fix spurious errors using `sendmmsg` with multiple cmsgs
- Added `Errno::EOPNOTSUPP` to FreeBSD, where it was missing.
### Removed
- Removed `sys::socket::accept4` from Android arm because libc removed it in
version 0.2.87.
- `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.
- Removed some Errno values from platforms where they aren't actually defined.

- Made `unistd::fork` an unsafe funtion, bringing it in line with [libstd's decision](https://github.com/rust-lang/rust/pull/58059).
## [0.18.0] - 26 July 2020

- Added support on linux systems for `MAP_HUGE_`_`SIZE`_ family of flags.
- Added support for `F_OFD_*` `fcntl` commands on Linux and Android.

where it's available, and clears the environment of all variables
via `std::env::vars` and `std::env::remove_var` on others.
- `FsType` inner value made public.
- Added `unistd::setfsuid` and `unistd::setfsgid` to set the user or group
identity for filesystem checks per-thread.
- 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.

### 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
- On Linux, `ptrace::write` is now an `unsafe` function. Caveat programmer.
- `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`.
- Several `Inotify` methods now take `self` by value instead of by reference
- `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.
- Fixed a bug in nix::unistd that would result in an infinite loop
when a group or user lookup required a buffer larger than
- 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.
- Fixed unaligned pointer read in `Inotify::read_events`.
### Removed
- Removed `sys::socket::addr::from_libc_sockaddr` from the public API.
- 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.
- 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.
- Removed `unistd::daemon` and `unistd::pipe2` on OSX and ios
- Removed `sys::event::FilterFlag::NOTE_EXIT_REPARENTED` and
`sys::event::FilterFlag::NOTE_REAP` on OSX and ios.

- Implemented `Default` for `FdSet`
- Added `NixPath::is_empty`.
- Added `mkfifoat`
- Added `User::from_uid`, `User::from_name`, `User::from_gid` and
`Group::from_name`,
- Added `linkat`
- Added `sched_getaffinity`.
- Added optional `Signal` argument to `ptrace::{detach, syscall}` for signal
### Changed
- `sys::termios::BaudRate` now implements `TryFrom<speed_t>` instead of
`From<speed_t>`. The old `From` implementation would panic on failure.
- `sys::socket::ControlMessage::ScmCredentials` and
`sys::socket::ControlMessageOwned::ScmCredentials` now wrap `UnixCredentials`
rather than `libc::ucred`.
- `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.
- `sys::socket::recvfrom` now returns
`Result<(usize, Option<SockAddr>)>` instead of `Result<(usize, SockAddr)>`.
- `Signal::from_c_int` has been replaced by `Signal::try_from`
- Changed `readlink` and `readlinkat` to return `OsString`
```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.
- `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.
- Type `&CString` for parameters of `exec(v|ve|vp|vpe|veat)` are changed to `&CStr`.
### Fixed

without importing the `convert_ioctl_res!` macro.
```rust
use nix::ioctl_read_bad;
ioctl_read_bad!(tcgets, libc::TCGETS, libc::termios);
```

### Changed
- `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 {
```
- Replaced `CmsgSpace` with the `cmsg_space` macro.
### Fixed
- Fixed multiple bugs when using `sendmsg` and `recvmsg` with ancillary control messages
- Macros exported by `nix` may now be imported via `use` on the Rust 2018
edition without importing helper macros for BSD targets.
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);
```

- Marked `sys::ptrace::ptrace` as `unsafe`.
- Changed function signature of `socket()` and `socketpair()`. The `protocol` argument
has changed type from `c_int` to `SockProtocol`.
It accepts a `None` value for default protocol that was specified with zero using `c_int`.
- Made `select` easier to use, adding the ability to automatically calculate the `nfds` parameter using the new
- Exposed `unistd::setresuid` and `unistd::setresgid` on FreeBSD and OpenBSD
- Refactored the `statvfs` module removing extraneous API functions and the
`statvfs::vfs` module. Additionally `(f)statvfs()` now return the struct
directly. And the returned `Statvfs` struct now exposes its data through
- The `addr` argument to `madvise` and `msync` is now `*mut` to better match the
- `shm_open` and `shm_unlink` are no longer exposed on Android targets, where
- `MapFlags`, `MmapAdvise`, and `MsFlags` expose some more variants and only

- Fix potential memory corruption on non-Linux platforms when using
`sendmsg`/`recvmsg`, caused by mismatched `msghdr` definition.
### Removed

`from_bytes` or `from_bytes_mut` instead.
- The syscall module has been removed. This only exposed enough functionality for
`memfd_create()` and `pivot_root()`, which are still exposed as separate functions.
- 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.

- Changed type signature of `sys::select::FdSet::contains` to make `self`
- 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
- 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`.
Also file system type constants like `nix::sys::statfs::ADFS_SUPER_MAGIC` were removed in favor of the libc equivalent.
- 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
- 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.
### Removed
- Removed `io::Error` from `nix::Error` and the conversion from `nix::Error` to `Errno`
- 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
- 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.
### Fixed
- Fixed multiple issues compiling under different archetectures and OSes.
- `bind` and `errno_location` now work correctly on `Android`
- Added `nix::ptrace` on all Linux-kernel-based platforms
only available on x86, x86-64, and ARM, and also not on Android.
- Fixed `sys::socket::sendmsg` with zero entry `cmsgs` parameter.
- Multiple constants related to the termios API have now been properly defined for
- `ioctl!` macro now supports working with non-int datatypes and properly supports all platforms.
## [0.8.1] 2017-04-16
### Fixed
- Fixed build on FreeBSD. (Cherry-picked
## [0.8.0] 2017-03-02
### Added
- Added `::nix::sys::termios::BaudRate` enum to provide portable baudrate
- Added a new `WaitStatus::PtraceEvent` to support ptrace events on Linux
- Added support for POSIX AIO
- Added support for XNU system control sockets
- Added support for `ioctl` calls on BSD platforms
- Added struct `TimeSpec`
- Added complete definitions for all kqueue-related constants on all supported
OSes
- Added function `epoll_create1` and bitflags `EpollCreateFlags` in
`::nix::sys::epoll` in order to support `::libc::epoll_create1`.
- Added `setresuid` and `setresgid` for Linux in `::nix::unistd`
- Added `getpgid` in `::nix::unistd`
- Added `tcgetpgrp` and `tcsetpgrp` in `::nix::unistd`
- Added `CLONE_NEWCGROUP` in `::nix::sched`
- Added `getpgrp` in `::nix::unistd`
- Added `fchdir` in `::nix::unistd`
- Added `major` and `minor` in `::nix::sys::stat` for decomposing `dev_t`
- Fixed the style of many bitflags and use `libc` in more places.
- Added `ppoll` in `::nix::poll`
- Added support for getting and setting pipe size with fcntl(2) on Linux
### Changed
- `::nix::sys::termios::{cfgetispeed, cfsetispeed, cfgetospeed, cfsetospeed}`
switched to use `BaudRate` enum from `speed_t`.
- `epoll_ctl` now could accept None as argument `event`
when op is `EpollOp::EpollCtlDel`.
- Removed the `bad` keyword from the `ioctl!` macro
- Changed `TimeVal` into an opaque Newtype
- `kill`'s signature, defined in `::nix::sys::signal`, changed, so that the
signal parameter has type `T: Into<Option<Signal>>`. `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`.
- The minimum supported version of rustc is now 1.7.0.
- Changed `KEvent` to an opaque structure that may only be modified by its
constructor and the `ev_set` method.
- `pipe2` now calls `libc::pipe2` where available. Previously it was emulated
using `pipe`, which meant that setting `O_CLOEXEC` was not atomic.
- Renamed `EpollEventKind` to `EpollFlags` in `::nix::sys::epoll` in order for
it to conform with our conventions.
- `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.
- `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.
- `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.
### Fixed
- Fixed multiple issues with Unix domain sockets on non-Linux OSes
- Fixed using kqueue with `EVFILT_USER` on FreeBSD
- Fixed the build on FreeBSD, and fixed the getsockopt, sendmsg, and recvmsg
functions on that same OS.
- Fixed an off-by-one bug in `UnixAddr::new_abstract` in `::nix::sys::socket`.
- Fixed clone passing a potentially unaligned stack.
- Fixed mkdev not creating a `dev_t` the same way as libc.
## [0.7.0] 2016-09-09
### Added
- Added `lseek` and `lseek64` in `::nix::unistd`
- Added `mkdir` and `getcwd` in `::nix::unistd`
- Added accessors `sigmask_mut` and `sigmask` to `UContext` in
`::nix::ucontext`.
- Added `WUNTRACED` to `WaitPidFlag` in `::nix::sys::wait` for non-_linux_
targets.
- Added new module `::nix::sys::reboot` with enumeration `RebootMode` and
functions `reboot` and `set_cad_enabled`. Currently for _linux_ only.
- `FdSet` in `::nix::sys::select` now also implements `Clone`.
- Added `F_FULLFSYNC` to `FcntlArg` in `::nix::fcntl` for _apple_ targets.
- Added `CpuSet::unset` in `::nix::sched`.
- Added constructor method `new()` to `PollFd` in `::nix::poll`, in order to
allow creation of objects, after removing public access to members.
- Added method `revents()` to `PollFd` in `::nix::poll`, in order to provide
read access to formerly public member `revents`.
- Added `MSG_CMSG_CLOEXEC` to `MsgFlags` in `::nix::sys::socket` for _linux_ only.
### Changed
- Replaced the reexported integer constants for signals by the enumeration
`Signal` in `::nix::sys::signal`.
- Renamed `EventFdFlag` to `EfdFlags` in `::nix::sys::eventfd`.
- Changed the result types of `CpuSet::is_set` and `CpuSet::set` in
`::nix::sched` to `Result<bool>` and `Result<()>`, respectively. They now
return `EINVAL`, if an invalid argument for the `field` parameter is passed.
- `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`.
- 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.
- 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.
### Removed
- Type alias `SigNum` from `::nix::sys::signal`.
- Type alias `CpuMask` from `::nix::shed`.
- Removed public fields from `PollFd` in `::nix::poll`. (See also added method
`revents()`.
### Fixed
- Fixed the build problem for NetBSD (Note, that we currently do not support
it, so it might already be broken again).
- Fixed the build on FreeBSD, and fixed the getsockopt, sendmsg, and recvmsg
functions on that same OS.
## [0.6.0] 2016-06-10
### Added
- Added `gettid` in `::nix::unistd` for _linux_ and _android_.
- Some _mips_ support in `::nix::sched` and `::nix::sys::syscall`.
- Added `SIGNALFD_SIGINFO_SIZE` in `::nix::sys::signalfd`.
- Added new module `::nix::ucontext` with struct `UContext`. Currently for
_linux_ only.

- Added `pause` to `::nix::unistd`.
- Added `sleep` to `::nix::unistd`.
- Added `S_IFDIR`, `S_IFLNK`, `S_IFMT` to `SFlag` in `::nix::sys::stat`.
- Added `clear` and `extend` functions to `SigSet`'s implementation in
`::nix::sys::signal`.
- `sockaddr_storage_to_addr` in `::nix::sys::socket` now supports `sockaddr_nl`
on _linux_ and _android_.
- Added support for `SO_ORIGINAL_DST` in `::nix::sys::socket` on _linux_.
- Added `SIGINFO` in `::nix::sys::signal` for the _macos_ target as well as
`SIGPWR` and `SIGSTKFLT` in `::nix::sys::signal` for non-_macos_ targets.
### Changed
- Changed the structure `IoVec` in `::nix::sys::uio`.
- Replaced `CREATE_NEW_FD` by `SIGNALFD_NEW` in `::nix::sys::signalfd`.
- Renamed `SaFlag` to `SaFlags` and `SigFlag` to `SigFlags` in
`::nix::sys::signal`.
- Renamed `Fork` to `ForkResult` and changed its fields in `::nix::unistd`.
- Added the `signal` parameter to `clone`'s signature in `::nix::sched`.
- `execv`, `execve`, and `execvp` now return `Result<Void>` instead of
`Result<()>` in `::nix::unistd`.
### Fixed
