1776: Add support for the IP_SENDSRCADDR control message r=rtzoeller a=matttpt This control message is available on FreeBSD, NetBSD, and OpenBSD. When used with `sendmsg`, it sets the IPv4 source address. This adds support through a new `ControlMessage::Ipv4SendSrcAddr` variant that complements `ControlMessageOwned::Ipv4RecvDstAddr`. A few notes: * `IP_SENDSRCADDR` is actually just an alias for `IP_RECVDSTADDR` (though the code doesn't depend on this). * On NetBSD, `IP_PKTINFO` can be used to accomplish the same thing and is already supported by nix. On FreeBSD and OpenBSD, though, `IP_SENDSRCADDR` is the only method I'm aware of. * The accompanying test binds a UDP socket to all local interfaces (0.0.0.0). If this is not acceptable, please let me know; however, FreeBSD requires this to use `IP_SENDSRCADDR`. I'll add a change-log entry once I see the PR number. Thanks!

2022-07-23Fix SockaddrLike::from_raw with unaligned inputsAlan Somers
The major users of this function are functions like gethostname, which will always properly align their buffers. But out-of-crate consumers could manually construct an unaligned buffer. Handle that correctly. Enable Clippy's cast_ptr_alignment lint. It's disabled by default as it reports many false positives, but it would've caught this problem. Reported-by: Miri Fixes: 1769

1741: SigSet: A new unsafe helper method to create a SigSet from a sigset_t r=rtzoeller a=germag Currently, the only way to create a `SigSet` from a `sigset_t` object is by using pointer casts, like: ``` unsafe { let sigset = *(&sigset as *const libc::sigset_t as *const SigSet) }; ``` This is un-ergonomic for library creators with interfaces to C. So, let's add a new unsafe method that creates a `SigSet` from a `libc::sigset_t` object. We can't implement `From` since converting from `libc::sigset_t` to `SigSet` is unsafe, because objects of type `libc::sigset_t` must be initialized by calling either `sigemptyset(3)` or `sigfillset(3)` before being used. In other case, the results are undefined. We can't implement `TryFrom` either, because there is no way to check if an object of type `libc::sigset_t` is initialized.
