The `protocol` argument 1198 has changed type from `c_int` to `SockProtocol`. 1199 It accepts a `None` value for default protocol that was specified with zero using `c_int`. 1200 ([#647](https://github.com/nix-rust/nix/pull/647)) 1201- Made `select` easier to use, adding the ability to automatically calculate the `nfds` parameter using the new 1202 `FdSet::highest` ([#701](https://github.com/nix-rust/nix/pull/701)) 1203- Exposed `unistd::setresuid` and `unistd::setresgid` on FreeBSD and OpenBSD 1204 ([#721](https://github.com/nix-rust/nix/pull/721)) 1205- Refactored the `statvfs` module removing extraneous API functions and the 1206 `statvfs::vfs` module. Additionally `(f)statvfs()` now return the struct 1207 directly. And the returned `Statvfs` struct now exposes its data through 1208 accessor methods. ([#729](https://github.com/nix-rust/nix/pull/729)) 1209- The `addr` argument to `madvise` and `msync` is now `*mut` to better match the 1210 libc API. ([#731](https://github.com/nix-rust/nix/pull/731)) 1211- `shm_open` and `shm_unlink` are no longer exposed on Android targets, where 1212 they are not officially supported.

See the module docs for 1233 `nix::sys::termios` for more details. 1234 ([#843](https://github.com/nix-rust/nix/pull/843)) 1235 1236### Fixed 1237- Fix compilation and tests for OpenBSD targets 1238 ([#688](https://github.com/nix-rust/nix/pull/688)) 1239- Fixed error handling in `AioCb::fsync`, `AioCb::read`, and `AioCb::write`. 1240 It is no longer an error to drop an `AioCb` that failed to enqueue in the OS. 1241 ([#715](https://github.com/nix-rust/nix/pull/715)) 1242- Fix potential memory corruption on non-Linux platforms when using 1243 `sendmsg`/`recvmsg`, caused by mismatched `msghdr` definition. 1244 ([#648](https://github.com/nix-rust/nix/pull/648)) 1245 1246### Removed 1247- `AioCb::from_boxed_slice` has been removed. It was never actually safe. Use 1248 `from_bytes` or `from_bytes_mut` instead. 1249 ([#820](https://github.com/nix-rust/nix/pull/820)) 1250- The syscall module has been removed. This only exposed enough functionality for 1251 `memfd_create()` and `pivot_root()`, which are still exposed as separate functions. 1252 ([#747](https://github.com/nix-rust/nix/pull/747)) 1253- The `Errno` variants are no longer reexported from the `errno` module. `Errno` itself is no longer reexported from the 1254 crate root and instead must be accessed using the `errno` module. ([#696](https://github.com/nix-rust/nix/pull/696)) 1255- Removed `MS_VERBOSE`, `MS_NOSEC`, and `MS_BORN` from `MsFlags`. These 1256 are internal kernel flags and should never have been exposed. 1257 ([#814](https://github.com/nix-rust/nix/pull/814)) 1258 1259 1260## [0.9.0] 2017-07-23 1261 1262### Added 1263- Added `sysconf`, `pathconf`, and `fpathconf` 1264 ([#630](https://github.com/nix-rust/nix/pull/630) 1265- Added `sys::signal::SigAction::{ flags, mask, handler}` 1266 ([#611](https://github.com/nix-rust/nix/pull/609) 1267- Added `nix::sys::pthread::pthread_self` 1268 ([#591](https://github.com/nix-rust/nix/pull/591) 1269- Added `AioCb::from_boxed_slice` 1270 ([#582](https://github.com/nix-rust/nix/pull/582) 1271- Added `nix::unistd::{openat, fstatat, readlink, readlinkat}` 1272 ([#551](https://github.com/nix-rust/nix/pull/551)) 1273- Added `nix::pty::{grantpt, posix_openpt, ptsname/ptsname_r, unlockpt}` 1274 ([#556](https://github.com/nix-rust/nix/pull/556) 1275- Added `nix::ptr::openpty` 1276 ([#456](https://github.com/nix-rust/nix/pull/456)) 1277- Added `nix::ptrace::{ptrace_get_data, ptrace_getsiginfo, ptrace_setsiginfo 1278 and nix::Error::UnsupportedOperation}` 1279 ([#614](https://github.com/nix-rust/nix/pull/614)) 1280- Added `cfmakeraw`, `cfsetspeed`, and `tcgetsid`.

([#661](https://github.com/nix-rust/nix/pull/661)) 1290- Changed `ioctl!(write ...)` into `ioctl!(write_ptr ...)` and `ioctl!(write_int ..)` variants 1291 to more clearly separate those use cases. ([#670](https://github.com/nix-rust/nix/pull/670)) 1292- Marked `sys::mman::{ mmap, munmap, madvise, munlock, msync }` as unsafe. 1293 ([#559](https://github.com/nix-rust/nix/pull/559)) 1294- Minimum supported Rust version is now 1.13. 1295- Removed `revents` argument from `PollFd::new()` as it's an output argument and 1296 will be overwritten regardless of value. 1297 ([#542](https://github.com/nix-rust/nix/pull/542)) 1298- Changed type signature of `sys::select::FdSet::contains` to make `self` 1299 immutable ([#564](https://github.com/nix-rust/nix/pull/564)) 1300- Introduced wrapper types for `gid_t`, `pid_t`, and `uid_t` as `Gid`, `Pid`, and `Uid` 1301 respectively. Various functions have been changed to use these new types as 1302 arguments. ([#629](https://github.com/nix-rust/nix/pull/629)) 1303- Fixed compilation on all Android and iOS targets ([#527](https://github.com/nix-rust/nix/pull/527)) 1304 and promoted them to Tier 2 support. 1305- `nix::sys::statfs::{statfs,fstatfs}` uses statfs definition from `libc::statfs` instead of own linux specific type `nix::sys::Statfs`. 1306 Also file system type constants like `nix::sys::statfs::ADFS_SUPER_MAGIC` were removed in favor of the libc equivalent. 1307 ([#561](https://github.com/nix-rust/nix/pull/561)) 1308- Revised the termios API including additional tests and documentation and exposed it on iOS. ([#527](https://github.com/nix-rust/nix/pull/527)) 1309- `eventfd`, `signalfd`, and `pwritev`/`preadv` functionality is now included by default for all 1310 supported platforms. ([#681](https://github.com/nix-rust/nix/pull/561)) 1311- The `ioctl!` macro's plain variants has been replaced with "bad read" to be consistent with 1312 other variants. The generated functions also have more strict types for their arguments. The 1313 "*_buf" variants also now calculate total array size and take slice references for improved type 1314 safety. The documentation has also been dramatically improved. 1315 ([#670](https://github.com/nix-rust/nix/pull/670)) 1316 1317### Removed 1318- Removed `io::Error` from `nix::Error` and the conversion from `nix::Error` to `Errno` 1319 ([#614](https://github.com/nix-rust/nix/pull/614)) 1320- All feature flags have been removed in favor of conditional compilation on supported platforms. 1321 `execvpe` is no longer supported, but this was already broken and will be added back in the next 1322 release. ([#681](https://github.com/nix-rust/nix/pull/561)) 1323- Removed `ioc_*` functions and many helper constants and macros within the `ioctl` module. These 1324 should always have been private and only the `ioctl!` should be used in public code. 1325 ([#670](https://github.com/nix-rust/nix/pull/670)) 1326 1327### Fixed 1328- Fixed multiple issues compiling under different archetectures and OSes. 1329 Now compiles on Linux/MIPS ([#538](https://github.com/nix-rust/nix/pull/538)), 1330 `Linux/PPC` ([#553](https://github.com/nix-rust/nix/pull/553)), 1331 `MacOS/x86_64,i686` ([#553](https://github.com/nix-rust/nix/pull/553)), 1332 `NetBSD/x64_64` ([#538](https://github.com/nix-rust/nix/pull/538)), 1333 `FreeBSD/x86_64,i686` ([#536](https://github.com/nix-rust/nix/pull/536)), and 1334 `Android` ([#631](https://github.com/nix-rust/nix/pull/631)). 1335- `bind` and `errno_location` now work correctly on `Android` 1336 ([#631](https://github.com/nix-rust/nix/pull/631)) 1337- Added `nix::ptrace` on all Linux-kernel-based platforms 1338 [#624](https://github.com/nix-rust/nix/pull/624). Previously it was 1339 only available on x86, x86-64, and ARM, and also not on Android. 1340- Fixed `sys::socket::sendmsg` with zero entry `cmsgs` parameter. 1341 ([#623](https://github.com/nix-rust/nix/pull/623)) 1342- Multiple constants related to the termios API have now been properly defined for 1343 all supported platforms. ([#527](https://github.com/nix-rust/nix/pull/527)) 1344- `ioctl!` macro now supports working with non-int datatypes and properly supports all platforms. 1345 ([#670](https://github.com/nix-rust/nix/pull/670)) 1346 1347## [0.8.1] 2017-04-16 1348 1349### Fixed 1350- Fixed build on FreeBSD. (Cherry-picked 1351 [a859ee3c](https://github.com/nix-rust/nix/commit/a859ee3c9396dfdb118fcc2c8ecc697e2d303467)) 1352 1353## [0.8.0] 2017-03-02 1354 1355### Added 1356- Added `::nix::sys::termios::BaudRate` enum to provide portable baudrate 1357 values. ([#518](https://github.com/nix-rust/nix/pull/518)) 1358- Added a new `WaitStatus::PtraceEvent` to support ptrace events on Linux 1359 and Android ([#438](https://github.com/nix-rust/nix/pull/438)) 1360- Added support for POSIX AIO 1361 ([#483](https://github.com/nix-rust/nix/pull/483)) 1362 ([#506](https://github.com/nix-rust/nix/pull/506)) 1363- Added support for XNU system control sockets 1364 ([#478](https://github.com/nix-rust/nix/pull/478)) 1365- Added support for `ioctl` calls on BSD platforms 1366 ([#478](https://github.com/nix-rust/nix/pull/478)) 1367- Added struct `TimeSpec` 1368 ([#475](https://github.com/nix-rust/nix/pull/475)) 1369 ([#483](https://github.com/nix-rust/nix/pull/483)) 1370- Added complete definitions for all kqueue-related constants on all supported 1371 OSes 1372 ([#415](https://github.com/nix-rust/nix/pull/415)) 1373- Added function `epoll_create1` and bitflags `EpollCreateFlags` in 1374 `::nix::sys::epoll` in order to support `::libc::epoll_create1`. 1375 ([#410](https://github.com/nix-rust/nix/pull/410)) 1376- Added `setresuid` and `setresgid` for Linux in `::nix::unistd` 1377 ([#448](https://github.com/nix-rust/nix/pull/448)) 1378- Added `getpgid` in `::nix::unistd` 1379 ([#433](https://github.com/nix-rust/nix/pull/433)) 1380- Added `tcgetpgrp` and `tcsetpgrp` in `::nix::unistd` 1381 ([#451](https://github.com/nix-rust/nix/pull/451)) 1382- Added `CLONE_NEWCGROUP` in `::nix::sched` 1383 ([#457](https://github.com/nix-rust/nix/pull/457)) 1384- Added `getpgrp` in `::nix::unistd` 1385 ([#491](https://github.com/nix-rust/nix/pull/491)) 1386- Added `fchdir` in `::nix::unistd` 1387 ([#497](https://github.com/nix-rust/nix/pull/497)) 1388- Added `major` and `minor` in `::nix::sys::stat` for decomposing `dev_t` 1389 ([#508](https://github.com/nix-rust/nix/pull/508)) 1390- Fixed the style of many bitflags and use `libc` in more places. 1391 ([#503](https://github.com/nix-rust/nix/pull/503)) 1392- Added `ppoll` in `::nix::poll` 1393 ([#520](https://github.com/nix-rust/nix/pull/520)) 1394- Added support for getting and setting pipe size with fcntl(2) on Linux 1395 ([#540](https://github.com/nix-rust/nix/pull/540)) 1396 1397### Changed 1398- `::nix::sys::termios::{cfgetispeed, cfsetispeed, cfgetospeed, cfsetospeed}` 1399 switched to use `BaudRate` enum from `speed_t`. 1400 ([#518](https://github.com/nix-rust/nix/pull/518)) 1401- `epoll_ctl` now could accept None as argument `event` 1402 when op is `EpollOp::EpollCtlDel`. 1403 ([#480](https://github.com/nix-rust/nix/pull/480)) 1404- Removed the `bad` keyword from the `ioctl!` macro 1405 ([#478](https://github.com/nix-rust/nix/pull/478)) 1406- Changed `TimeVal` into an opaque Newtype 1407 ([#475](https://github.com/nix-rust/nix/pull/475)) 1408- `kill`'s signature, defined in `::nix::sys::signal`, changed, so that the 1409 signal parameter has type `T: Into<Option<Signal>>`. `None` as an argument 1410 for that parameter will result in a 0 passed to libc's `kill`, while a 1411 `Some`-argument will result in the previous behavior for the contained 1412 `Signal`. 1413 ([#445](https://github.com/nix-rust/nix/pull/445)) 1414- The minimum supported version of rustc is now 1.7.0. 1415 ([#444](https://github.com/nix-rust/nix/pull/444)) 1416- Changed `KEvent` to an opaque structure that may only be modified by its 1417 constructor and the `ev_set` method. 1418 ([#415](https://github.com/nix-rust/nix/pull/415)) 1419 ([#442](https://github.com/nix-rust/nix/pull/442)) 1420 ([#463](https://github.com/nix-rust/nix/pull/463)) 1421- `pipe2` now calls `libc::pipe2` where available. Previously it was emulated 1422 using `pipe`, which meant that setting `O_CLOEXEC` was not atomic. 1423 ([#427](https://github.com/nix-rust/nix/pull/427)) 1424- Renamed `EpollEventKind` to `EpollFlags` in `::nix::sys::epoll` in order for 1425 it to conform with our conventions. 1426 ([#410](https://github.com/nix-rust/nix/pull/410)) 1427- `EpollEvent` in `::nix::sys::epoll` is now an opaque proxy for 1428 `::libc::epoll_event`. The formerly public field `events` is now be read-only 1429 accessible with the new method `events()` of `EpollEvent`. Instances of 1430 `EpollEvent` can be constructed using the new method `new()` of EpollEvent. 1431 ([#410](https://github.com/nix-rust/nix/pull/410)) 1432- `SigFlags` in `::nix::sys::signal` has be renamed to `SigmaskHow` and its type 1433 has changed from `bitflags` to `enum` in order to conform to our conventions. 1434 ([#460](https://github.com/nix-rust/nix/pull/460)) 1435- `sethostname` now takes a `&str` instead of a `&[u8]` as this provides an API 1436 that makes more sense in normal, correct usage of the API. 1437- `gethostname` previously did not expose the actual length of the hostname 1438 written from the underlying system call at all. This has been updated to 1439 return a `&CStr` within the provided buffer that is always properly 1440 NUL-terminated (this is not guaranteed by the call with all platforms/libc 1441 implementations). 1442- Exposed all fcntl(2) operations at the module level, so they can be 1443 imported direclty instead of via `FcntlArg` enum. 1444 ([#541](https://github.com/nix-rust/nix/pull/541)) 1445 1446### Fixed 1447- Fixed multiple issues with Unix domain sockets on non-Linux OSes 1448 ([#474](https://github.com/nix-rust/nix/pull/415)) 1449- Fixed using kqueue with `EVFILT_USER` on FreeBSD 1450 ([#415](https://github.com/nix-rust/nix/pull/415)) 1451- Fixed the build on FreeBSD, and fixed the getsockopt, sendmsg, and recvmsg 1452 functions on that same OS. 1453 ([#397](https://github.com/nix-rust/nix/pull/397)) 1454- Fixed an off-by-one bug in `UnixAddr::new_abstract` in `::nix::sys::socket`. 1455 ([#429](https://github.com/nix-rust/nix/pull/429)) 1456- Fixed clone passing a potentially unaligned stack. 1457 ([#490](https://github.com/nix-rust/nix/pull/490)) 1458- Fixed mkdev not creating a `dev_t` the same way as libc. 1459 ([#508](https://github.com/nix-rust/nix/pull/508)) 1460 1461## [0.7.0] 2016-09-09 1462 1463### Added 1464- Added `lseek` and `lseek64` in `::nix::unistd` 1465 ([#377](https://github.com/nix-rust/nix/pull/377)) 1466- Added `mkdir` and `getcwd` in `::nix::unistd` 1467 ([#416](https://github.com/nix-rust/nix/pull/416)) 1468- Added accessors `sigmask_mut` and `sigmask` to `UContext` in 1469 `::nix::ucontext`. 1470 ([#370](https://github.com/nix-rust/nix/pull/370)) 1471- Added `WUNTRACED` to `WaitPidFlag` in `::nix::sys::wait` for non-_linux_ 1472 targets. 1473 ([#379](https://github.com/nix-rust/nix/pull/379)) 1474- Added new module `::nix::sys::reboot` with enumeration `RebootMode` and 1475 functions `reboot` and `set_cad_enabled`. Currently for _linux_ only. 1476 ([#386](https://github.com/nix-rust/nix/pull/386)) 1477- `FdSet` in `::nix::sys::select` now also implements `Clone`. 1478 ([#405](https://github.com/nix-rust/nix/pull/405)) 1479- Added `F_FULLFSYNC` to `FcntlArg` in `::nix::fcntl` for _apple_ targets. 1480 ([#407](https://github.com/nix-rust/nix/pull/407)) 1481- Added `CpuSet::unset` in `::nix::sched`. 1482 ([#402](https://github.com/nix-rust/nix/pull/402)) 1483- Added constructor method `new()` to `PollFd` in `::nix::poll`, in order to 1484 allow creation of objects, after removing public access to members. 1485 ([#399](https://github.com/nix-rust/nix/pull/399)) 1486- Added method `revents()` to `PollFd` in `::nix::poll`, in order to provide 1487 read access to formerly public member `revents`. 1488 ([#399](https://github.com/nix-rust/nix/pull/399)) 1489- Added `MSG_CMSG_CLOEXEC` to `MsgFlags` in `::nix::sys::socket` for _linux_ only. 1490 ([#422](https://github.com/nix-rust/nix/pull/422)) 1491 1492### Changed 1493- Replaced the reexported integer constants for signals by the enumeration 1494 `Signal` in `::nix::sys::signal`. 1495 ([#362](https://github.com/nix-rust/nix/pull/362)) 1496- Renamed `EventFdFlag` to `EfdFlags` in `::nix::sys::eventfd`. 1497 ([#383](https://github.com/nix-rust/nix/pull/383)) 1498- Changed the result types of `CpuSet::is_set` and `CpuSet::set` in 1499 `::nix::sched` to `Result<bool>` and `Result<()>`, respectively. They now 1500 return `EINVAL`, if an invalid argument for the `field` parameter is passed. 1501 ([#402](https://github.com/nix-rust/nix/pull/402)) 1502- `MqAttr` in `::nix::mqueue` is now an opaque proxy for `::libc::mq_attr`, 1503 which has the same structure as the old `MqAttr`. The field `mq_flags` of 1504 `::libc::mq_attr` is readable using the new method `flags()` of `MqAttr`. 1505 `MqAttr` also no longer implements `Debug`. 1506 ([#392](https://github.com/nix-rust/nix/pull/392)) 1507- The parameter `msq_prio` of `mq_receive` with type `u32` in `::nix::mqueue` 1508 was replaced by a parameter named `msg_prio` with type `&mut u32`, so that 1509 the message priority can be obtained by the caller. 1510 ([#392](https://github.com/nix-rust/nix/pull/392)) 1511- The type alias `MQd` in `::nix::queue` was replaced by the type alias 1512 `libc::mqd_t`, both of which are aliases for the same type. 1513 ([#392](https://github.com/nix-rust/nix/pull/392)) 1514 1515### Removed 1516- Type alias `SigNum` from `::nix::sys::signal`. 1517 ([#362](https://github.com/nix-rust/nix/pull/362)) 1518- Type alias `CpuMask` from `::nix::shed`. 1519 ([#402](https://github.com/nix-rust/nix/pull/402)) 1520- Removed public fields from `PollFd` in `::nix::poll`. (See also added method 1521 `revents()`. 1522 ([#399](https://github.com/nix-rust/nix/pull/399)) 1523 1524### Fixed 1525- Fixed the build problem for NetBSD (Note, that we currently do not support 1526 it, so it might already be broken again). 1527 ([#389](https://github.com/nix-rust/nix/pull/389)) 1528- Fixed the build on FreeBSD, and fixed the getsockopt, sendmsg, and recvmsg 1529 functions on that same OS. 1530 ([#397](https://github.com/nix-rust/nix/pull/397)) 1531 1532## [0.6.0] 2016-06-10 1533 1534### Added 1535- Added `gettid` in `::nix::unistd` for _linux_ and _android_. 1536 ([#293](https://github.com/nix-rust/nix/pull/293)) 1537- Some _mips_ support in `::nix::sched` and `::nix::sys::syscall`. 1538 ([#301](https://github.com/nix-rust/nix/pull/301)) 1539- Added `SIGNALFD_SIGINFO_SIZE` in `::nix::sys::signalfd`. 1540 ([#309](https://github.com/nix-rust/nix/pull/309)) 1541- Added new module `::nix::ucontext` with struct `UContext`. Currently for 1542 _linux_ only. 1543 ([#311](https://github.com/nix-rust/nix/pull/311)) 1544- Added `EPOLLEXCLUSIVE` to `EpollEventKind` in `::nix::sys::epoll`. 1545 ([#330](https://github.com/nix-rust/nix/pull/330)) 1546- Added `pause` to `::nix::unistd`. 1547 ([#336](https://github.com/nix-rust/nix/pull/336)) 1548- Added `sleep` to `::nix::unistd`. 1549 ([#351](https://github.com/nix-rust/nix/pull/351)) 1550- Added `S_IFDIR`, `S_IFLNK`, `S_IFMT` to `SFlag` in `::nix::sys::stat`. 1551 ([#359](https://github.com/nix-rust/nix/pull/359)) 1552- Added `clear` and `extend` functions to `SigSet`'s implementation in 1553 `::nix::sys::signal`. 1554 ([#347](https://github.com/nix-rust/nix/pull/347)) 1555- `sockaddr_storage_to_addr` in `::nix::sys::socket` now supports `sockaddr_nl` 1556 on _linux_ and _android_. 1557 ([#366](https://github.com/nix-rust/nix/pull/366)) 1558- Added support for `SO_ORIGINAL_DST` in `::nix::sys::socket` on _linux_. 1559 ([#367](https://github.com/nix-rust/nix/pull/367)) 1560- Added `SIGINFO` in `::nix::sys::signal` for the _macos_ target as well as 1561 `SIGPWR` and `SIGSTKFLT` in `::nix::sys::signal` for non-_macos_ targets. 1562 ([#361](https://github.com/nix-rust/nix/pull/361)) 1563 1564### Changed 1565- Changed the structure `IoVec` in `::nix::sys::uio`. 1566 ([#304](https://github.com/nix-rust/nix/pull/304)) 1567- Replaced `CREATE_NEW_FD` by `SIGNALFD_NEW` in `::nix::sys::signalfd`. 1568 ([#309](https://github.com/nix-rust/nix/pull/309)) 1569- Renamed `SaFlag` to `SaFlags` and `SigFlag` to `SigFlags` in 1570 `::nix::sys::signal`. 1571 ([#314](https://github.com/nix-rust/nix/pull/314)) 1572- Renamed `Fork` to `ForkResult` and changed its fields in `::nix::unistd`. 1573 ([#332](https://github.com/nix-rust/nix/pull/332)) 1574- Added the `signal` parameter to `clone`'s signature in `::nix::sched`. 1575 ([#344](https://github.com/nix-rust/nix/pull/344)) 1576- `execv`, `execve`, and `execvp` now return `Result<Void>` instead of 1577 `Result<()>` in `::nix::unistd`. 1578 ([#357](https://github.com/nix-rust/nix/pull/357)) 1579 1580### Fixed 1581- Improved the conversion from `std::net::SocketAddr` to `InetAddr` in 1582 `::nix::sys::socket::addr`. 1583 ([#335](https://github.com/nix-rust/nix/pull/335)) 1584 1585## [0.5.0] 2016-03-01 1586
