2017-03-18Actually mark mmap and related functions as `unsafe`Kevin Mehall
The nix::sys::mman::mmap documentation says > Calls to mmap are inherently unsafe, so they must be made in an unsafe block. however, the function was not actually marked unsafe. * `munmap` should also be `unsafe` for obvious reasons. * `madvise` should be `unsafe` because of the MADV_DONTNEED flag. * `mlock` was already marked `unsafe` * `munlock` and `msync` don't strictly need to be `unsafe` despite taking pointers AFAICT, but are marked `unsafe` for consistency and in case they add additional flags in the future.
2017-03-02Remove revents from PollFd::newBryant Mairs
revents is an output field so regardless of what value it is set to it will be overwritten by many of the function calls that take a PollFd. The only value that makes sense for the caller to pass in in `EventFlags::empty()` so we just hardcode that instead of making the caller do it.
2017-02-28fcntl: Expose FcntlArg variants at the module levelKamal Marhubi
This allows importing them directly from `nix::fcntl` which is more ergonomic than needing to use them via `FcntlArg`.

2017-02-27Auto merge of #506 - asomers:aio3, r=posborneHomu
Improve AIO API - Turn most `aio_*` functions into `AioCb` methods - Add runtime checks to `AioCb` methods - Implement `Drop` for `AioCb`
2017-02-26Auto merge of #520 - Susurrus:master, r=fiveopHomu
Add ppoll() This will currently fail CI, as the necessary changes haven't hit libc yet. That is tracked in rust-lang/libc#537. This does build on my computer using the changes tracked on that PR, so I'd appreciate any visual review of this code as it should be "done". I also wanted to get this submitted so hopefully it'd be in the queue for the 0.8 release.
2017-02-26Auto merge of #526 - Fulkerson:master, r=posborneHomu
Remove EPOLLWAKEUP and SIGEV_THREAD_ID when cross-compiling to MIPS. With this nix builds for mipsel-unknown-linux-gnu.
2017-02-26Auto merge of #518 - berkowski:baud_constants, r=posborneHomu
Added BaudRate enum for termios Issue #514 Does not provide `BaudRate::EXTA` or `BaudRate::EXTB` constants. These seem to alias to `B19200` and `B38400` respectively and so break the 1:1 mapping needed by `From`. I don't know their historic use.

2017-02-23Auto merge of #503 - Idolf:bitflags, r=kamalmarhubiHomu
Fix the style for bitflags! Prefer `libc_bitflags!` over `bitflags!`. Prefer `libc::CONSTANTS` over writing the constant manually. This makes #501 unnecessary, since upstream now contains the `O_TMPFILE` constant.

2017-02-18Auto merge of #508 - aidanhs:aphs-major-minor-macros, r=posborneHomu
Implement major/minor macros, correct mkdev It appears that the previous `mkdev` was based on the kernel headers (https://github.com/torvalds/linux/blob/v4.7/include/linux/kdev_t.h#L6) which (I guess) is the internal kernel dev_t. Scrolling down the file you can see some bitshifting operations to do conversions. The new implementation(s) are based on [musl](http://git.musl-libc.org/cgit/musl/tree/include/sys/sysmacros.h?id=dbbb3734d8c0176feabd6c46e2e85bbc3b8a60af) and [glibc](https://github.molgen.mpg.de/git-mirror/glibc/blob/20003c49884422da7ffbc459cdeee768a6fee07b/sysdeps/unix/sysv/linux/sys/sysmacros.h#L38), which are in agreement about how dev_t should be handled. (as it happens I suspect we could omit the shift by 32 since I don't see that in the kernel headers, but doesn't hurt to take the conservative route and mimic the libcs)

2017-02-14Auto merge of #438 - chaosagent:wait-ptrace, r=kamalmarhubiHomu
wait: Support ptrace events for Linux Adds new WaitStatus value `PtraceEvent`. Implementation of #273 that only affects Linux/Android.
2017-02-05Implement Drop for AioCbAlan Somers
If an AioCb has any in-kernel state, AioCb.drop will print a warning and wait for it to complete.
2017-02-05Add runtime checks to AioCb methodsAlan Somers
Prevent immutable buffers from being used with aio_read or lio_listio with LIO_READ. AioCb.from_slice no longer needs to be unsafe.

2017-01-26Auto merge of #483 - asomers:aio2, r=posborneHomu
Add POSIX AIO support POSIX AIO is a standard for asynchronous file I/O. Read, write, and fsync operations can all take place in the background, with completion notification delivered by a signal, by a new thread, by kqueue, or not at all. The SigEvent class, used for AIO notifications among other things, is also added.

2017-01-19unistd: add fchdir(2)Luca Bruno
This introduces a wrapper for fchdir(2), allowing a process to change directory based on an open file descriptor. The underlying function is available in libc crate since 0.2.20.
2017-01-15sethostname: convert to taking OsStr refPaul Osborne
Baed on discussions on the related PR, sethostname now takes an `S: AsRef<OsStr>` in order to allow for a greater range of inputs that allow for a more fluid interface. Signed-off-by: Paul Osborne <osbpau@gmail.com>
2017-01-15unistd: document and change implementation of gethostnamePaul Osborne
Previously gethostname just mutated a buffer. We now provide a slightly more usable (but still allocation free) API that ensures that the returned buffer is NUL-terminated. We give back a `&CStr` instead of requiring that the user do all of the conversions from `&[u8]` when we know we are dealing with a `&CStr`. Signed-off-by: Paul Osborne <osbpau@gmail.com>
2017-01-15unistd: add docs for gethostname and tweak APIPaul Osborne
Although the underlying C API does take a pointer to a set of characters, it is a requirement of almost every operating system that these bytes not contain a premature NUL character or other special characters. In other words, you want a `&str`. Changing this to make the API make a bit more sense. Signed-off-by: Paul Osborne <osbpau@gmail.com>

2017-01-11Auto merge of #489 - fiveop:fixcopyinto, r=fiveopHomu
Fix ControlMessage::encode_into when encoding multiple messages copy_bytes updates dst so that it points after the bytes that were just copied into it. encode_into did not advance the buffer in the same way when encoding the data. See #473

2016-12-16Add POSIX AIO supportAlan Somers
POSIX AIO is a standard for asynchronous file I/O. Read, write, and fsync operations can all take place in the background, with completion notification delivered by a signal, by a new thread, by kqueue, or not at all. This commit supports all standard AIO functions. However, lio_listio is disabled on macos because it doesn't seem to work, even though the syscall is present. The SigEvent class, used for AIO notifications among other things, is also added. Also, impl AsRef for TimeVal and TimeSpec
2016-12-17Auto merge of #478 - conradev:sys-control, r=fiveopHomu
Add support for system control sockets for XNU I added support for macOS and iOS system sockets, which can be used to control the kernel as described [here](https://developer.apple.com/library/content/documentation/Darwin/Conceptual/NKEConceptual/control/control.html). To do this, I had to add in support for `ioctl` on those platforms, so I added in `ioctl` support for all BSD-based platforms. The API seems to be the same between [xnu](https://opensource.apple.com/source/xnu/xnu-3248.60.10/bsd/sys/ioccom.h.auto.html), [FreeBSD](https://github.com/freebsd/freebsd/blob/master/sys/sys/ioccom.h), [NetBSD](https://ftp.netbsd.org/pub/NetBSD/NetBSD-current/src/sys/sys/ioccom.h), [OpenBSD](http://cvsweb.openbsd.org/cgi-bin/cvsweb/src/sys/sys/ioccom.h?rev=1.5&content-type=text/x-cvsweb-markup) and [Dragonfly BSD](http://gitweb.dragonflybsd.org/dragonfly.git/blob/HEAD:/sys/sys/ioccom.h). I added a test that runs on macOS and iOS for the functionality. Let me know if I need to make any changes!
2016-12-17Auto merge of #490 - kevindejong:master, r=fiveopHomu
Ensure child stack passed to clone is 16 byte aligned. The current implementation assumes that the array passed by the caller is word aligned (which I don't think Rust guarantees for [u8]) and a multiple of the word size.
