1216: Add UnixCredentials support on FreeBSD/DragonFly r=asomers a=myfreeweb This allows working with `SCM_CREDS` messages, which are like `SCM_CREDENTIALS` on Linux, but slightly different (always overwritten by the kernel, contain a bit more info — euid and groups). With this PR, it is possible to write portable code that would use the appropriate message for the platform, but one remaining quirk is that `PassCred` thing still has to be present and `cfg`'d to Linux. Adding the `SCM_CREDS` constant to libc: https://github.com/rust-lang/libc/pull/1740 Co-authored-by: Greg V <greg@unrelenting.technology>

1215: Remove sys::socket::addr::from_libc_sockaddr from the public API r=posborne a=asomers This function never should've been public, since it's basically impossible to use directly. It's only public due to an oversight from PR #667 . Co-authored-by: Alan Somers <asomers@gmail.com>

1208: Support sendmmsg/recvmmsg r=asomers a=glebpom This pull request adds `sendmmsg` and `recvmmsg` functions. They are used to send and receive multiple messages per one call. Additionally, `AsMut` implemented for both `TimeSpec` and `TimeVal`. This is still WIP, because we need to find the best way on how to pass multiple values to *mmsg functions. Current approach with iterators doesn't seem ergonomic. Co-authored-by: Gleb Pomykalov <gleb@lancastr.com> Co-authored-by: Alan Somers <asomers@gmail.com>

1209: Support UDP GSO and GRO on linux r=asomers a=glebpom This PR implements support for UDP GSO and GRO on Linux. It provides the way to send/receive UDP payloads bigger than interface MTU. The goal is to improve UDP performance. GSO was introduced in Linux 4.18, GRO in 5.3 Co-authored-by: Gleb Pomykalov <gleb@lancastr.com>

1207: Add select::FdSet::fds() method r=asomers a=zombiezen To be more consistent with most Rust APIs and enable cloning of the iterator, I made `FdSet::contains` operate on an immutable borrow instead of a mutable one by copying the set. If this is not desirable, I can roll that back from this PR and focus purely on the `fds()` method. Co-authored-by: Ross Light <ross@zombiezen.com>

1206: Fix unaligned casting of cmsg data to af_alg_iv r=asomers a=glebpom Casting a pointer to `cmsg_data` to `af_alg_iv` is incorrect since it's not properly aligned. As of the [`cmsg` man page](http://man7.org/linux/man-pages/man3/cmsg.3.html) "Applications should not cast it to a pointer type matching the payload, but should instead use memcpy(3) to copy data to or from a suitably declared object."

1205: unistd: avoid infinite loop caused by reserve_double_buffer_size r=asomers a=stevendanna Functions such as Group::from_anything use reserve_double_buffer_size in a loop, expecting it to return ERANGE if the passed limit is reached. However, the returned vector is passed as pointer to a libc function that writes data into memory and doesn't update the length of the Vec. Because of this, the previous code would never return ERANGE and the calling loops would never exit if they hit a case where the required buffer was larger than the maximum buffer. This fixes the problem by checking the capacity rather than the length. Signed-off-by: Steven Danna <steve@chef.io> Co-authored-by: Steven Danna <steve@chef.io>
