2022-08-05Add support for the IP_SENDSRCADDR control messageMatthew Ingwersen
This control message (actually just an alias for IP_RECVDSTADDR) sets the IPv4 source address when used with sendmsg. It is available on FreeBSD, NetBSD, OpenBSD, and DragonFlyBSD.

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

2022-05-02Restore conversions from ip v4/6 Sockaddr types to std::net equivalents.Kyle Huey
Fixes #1710
2022-04-22Fix UnixAddr::size on Linux and AndroidAlan Somers
SockaddrLike::size() is meant to return the amount of space that can be used to store the sockaddr. But on Linux-based OSes, UnixAddr contains an extra field to store the address's length. This field is not part of the address, and should not contribute to the value of size(). This bug can't cause an out-of-bounds write, and every OS that we test on can tolerate the greater-than-expected length, but it might confuse applications that implement functions similar to getsockname in userland.

1643: Replace the IoVec struct with IoSlice and IoSliceMut from the standard library r=asomers a=notgull As per discussion in #1637, the `IoVec<&[u8]>` and `IoVec<&mut [u8]>` types have been replaced with `std::io::IoSlice` and `IoSliceMut`, respectively. Notable changes made in this pull request include: - The complete replacement of `IoVec` with `IoSlice*` types in both public API, private API, and tests. - Replacing `IoVec` with `IoSlice` in docs. - Replacing `&[IoVec<&mut [u8]>]` with `&mut [IoSliceMut]`, note that the slice requires a mutable reference now. This is how it's done in the standard library, and there might be a soundness issue in doing it the other way. Resolves #1637 Co-authored-by: not_a_seagull <notaseagull048@gmail.com>

Because they're redundant with types in the standard library. Fixes #1681
2022-03-21Replace the Sockaddr enum with a unionAlan Somers
The SockAddr enum is quite large, and the user must allocate space for the whole thing even though he usually knows what type he needs. Furthermore, thanks to the sa_family field, the sockaddr types are basically an enum even in C. So replace the ungainly enum with a SockaddrLike trait implemented by all sockaddr types and a SockaddrStorage union that has safe accessors. Also, deprecate InetAddr, which only existed to support SockAddr. Supplants #1504 Fixes #1544

2022-03-13Fix a panic in Linkaddr::addrAlan Somers
The function assumed something about the values of the sockaddr_dl's fields. But because the inner type is public, we musn't do that. The only solution is to change the function's signature to return an Option.

This is more similar to how other sockaddr types work, and it's the same way that the BSDs use the sun_len field. Also, don't require that sun_path be nul-terminated. The OS doesn't require it. * On BSD-derived operating systems, struct sockaddr has a sa_len field that holds the length of the structure. UnixAddr's path_len field is redundant.

2021-12-30Optimize UnixAddr for the BSDsAlan Somers
On BSD-derived operating systems, struct sockaddr has a sa_len field that holds the length of the structure. UnixAddr's path_len field is redundant. Remove path_len on BSD-derived OSes, retaining it only for Illumos and Linux-based OSes. Also, ensure that two UnixAddrs compare equal if they differ only by the presence of a trailing NUL. On Linux, syscalls like getsockname add a trailing NUL to the sockaddr they return, even if no NUL was present on the sockaddr originally passed to the kernel via a syscall like bind, and even though the docs explicitly say that any NUL passed to bind is not considered to be part of the address. Work around this bug by stripping it in UnixAddrKind::get(), so that at least two UnixAddrs will compare identical even if they differ in the presence of a trailing NUL.

2021-10-09sockopt's Set and Get traits are not unsafeAlan Somers
They were properly marked as unsafe as originally written. However, when the internal mem::zeroed() was replaced by mem::uninitialized(), these traits actually became safe. Only Get::assume_init() is actually unsafe. Fixes a warning with the latest Clippy.

2021-09-06Add support for IP_RECVERR and IPV6_RECVERRConrad Meyer
Setting these options enables receiving errors, such as ICMP errors from the network, via `recvmsg()` with `MSG_ERRQUEUE`. Adds new `Ipv{4,6}RecvErr` variants to `ControlMessageOwned`. These control messages are produced when `Ipv4RecvErr` or `Ipv6RecvErr` options are enabled on a raw or datagram socket. New tests for the functionality can be run with `cargo test --test test test_recverr`. This commit builds on an earlier draft of the functionality authored by Matthew McPherrin <git@mcpherrin.ca>.
