2018-09-03new dir moduleScott Lamb
This is a lower-level interface than `std::fs::ReadDir`. Notable differences: * can be opened from a file descriptor (as returned by `openat`, perhaps before knowing if the path represents a file or directory). Uses `fdopendir` for this, available on all Unix platforms as of rust-lang/libc#1018. * implements `AsRawFd`, so it can be passed to `fstat`, `openat`, etc. * can be iterated through multiple times without closing and reopening the file descriptor. Each iteration rewinds when finished. * returns entries for `.` (current directory) and `..` (parent directory). * returns entries' names as a `CStr` (no allocation or conversion beyond whatever libc does).

923: Fix control message *decoding* and add support for `ScmCredentials` r=asomers a=jonas-schievink While https://github.com/nix-rust/nix/pull/918 fixed the *encoding*, the *decoding* done by the `CmsgIterator` still remained broken when multiple messages are received. However, since nix didn't support any control message that could reliably be sent twice in one `sendmsg` call, this couldn't be tested properly. This PR addresses this by adding `SCM_CREDENTIALS` support and testing all of this by passing both an `SCM_CREDENTIALS` and a `SCM_RIGHTS` message at the same time. I've also verified that the resulting encoding is the same as for roughly equivalent C code. Co-authored-by: Jonas Schievink <jonasschievink@gmail.com>

921: Get `SO_PEERCRED` working on all Linux targets r=asomers a=jonas-schievink These were disabled for ARM way back in 0db6ed1a28b4fb4d408cd9b7c4dba0a79bccf1f7 and 09c00ed7d9d92db2a79baa3ed212e7e239edceb9. Try to enable them for all arches and Android as well, since the removal wasn't really explained and I see no reason why this shouldn't work.

907: Remove emulation of FD_CLOEXEC/O_NONBLOCK r=asomers a=Susurrus Rather than using the native implementation of these constants on supported platforms, the native implementation was instead emulated. This was also hidden from the user even though this could result in data races and the functionality being broken. Native functionality is, however, not support on macos/ios. Rather than enable this emulation solely for this platform, it should be removed as this is a dangerous abstraction. This is a replacement for #863. There is much previous discussion there which I recommend you read to familiarize yourself with this decision. I'm looking to push this through rather quickly as it's the last thing blocking our next 0.11.0 release. cc @aomser @kristate Co-authored-by: Bryant Mairs <bryantmairs@google.com>

892: Fixed ptrace::Request cfg conditions r=asomers a=dalance The cfg condition of ptrace::Request seems to be different from libc. For example, PTRACE_GETREGS is defined by libc to i686-unknown-linux-gnu target, but it is not defined in ptrace::Request. I tried to change the cfg condition to the same as libc's condition.
