2021-04-04Use memoffset::offset_of instead of homegrown macroAlan Somers
The homegrown macro was fine in 2016, but at some point it technically became UB. The memoffset crate does the same thing, but avoids UB when using rustc 1.51.0 or later. Fixes #1415

2021-03-05Allow sockaddr_ll size mismatchJustin Ossevoort
Apparently the Linux kernel can return smaller sizes when the value in the last element of sockaddr_ll (`sll_addr`) is smaller than the declared size of that field.

2020-11-27Fix recvmmsg(2) implementationToby DiPasquale
There were two problems discovered with the `recvmmsg(2)` implementation that this changeset attempts to fix: 1. As mentioned in nix-rust/issues/1325, `recvmmsg(2)` can return fewer messages than requested, and 2. Passing the return value of `recvmmsg(2)` as the number of bytes in the messages received is incorrect. This changeset incorporates the proposed fix from nix-rust/issues/1325, as well as passing the correct value (`mmsghdr.msg_len`) for the number of bytes in a given message.

2020-08-18Add Netlink Protocol Families to SockProtocol enumsinkingpoint
Currently the SockProtocol enum is rather scarce. This commit adds the Netlink protocols defined in netlink(7) to the SockProtocol enum allowing us to use the Nix socket library for more indepth Netlink work
2020-07-04Expose IP_PKTINFO Control Message on AndroidBruno Tavares
The commit https://github.com/nix-rust/nix/pull/1222 added the very useful Ipv4PktInfo to allow `sendmsg` to define the origin of the ip. Unfortunattely, it didn't add the struct to Android target devices as well. This commit adds the `target_os = "android"` checks on the same place to allow the compilation to work for the following archs tested: - `cross build --target aarch64-linux-android` - `cross build --target x86_64-linux-android` - `cross build --target armv7-linux-androideabi` Also introduces iOS to allow using on libs for those platforms
2020-06-27Make SockAddr::as_ffi_pair safeAlan Somers
It was only marked unsafe because it did a pointer cast, but that particular pointer cast is always allowed by C.

2020-06-27Make sys::socket::sockaddr_storage a safe functionAlan Somers
It already fully validated its arguments, so there's no need for it to be `unsafe`.
2020-06-26Add Ipv{4,6}PacketInfo support to ControlMessage for send{m,}msgPerry Lorier
This adds Ipv4PacketInfo and Ipv6PacketInfo to ControlMessage, allowing these to be used with sendmsg/sendmmsg. This change contains the following squashed commits: Add Ipv{4,6}PacketInfo to ControlMessage. Add documentation links to Ipv{4,6}PacketInfo Add changelog entry for Ipv{4,6}PacketInfo Add link to PR in the Changelog. Add extra build environments. Add tests for Ipv{4,6}PacketInfo. Swap #[test] and #[cfg] The CI appears to be running the test, even though it's not cfg'd for that platform. I _think_ this might be due to these being in the wrong order. So lets try swapping them. s/freebsd/netbsd/ for Ipv4PacketInfo netbsd supports in_pktinfo, not freebsd. Fix the cfg for Ipv{4,6}PacketInfo usage. Ah, I see what I did wrong. I had fixed the definitions, but I had the wrong cfg() in the usage. This has the usage match the definitions. Change SOL_IPV6 to IPPROTO_IPV6. FreeBSD doesn't have SOL_IPV6, but does have IPPROTO_IPV6, and the two constants are defined as being equal. So change to use IPPROTO_IPV6. Skip Ipv6PacketInfo test if v6 is not available. If IPv6 is not available, then when we try and bind to ip6-localhost, we'll get a EADDRNOTAVAIL, so skip the test. This should mean that the test will run on any machine that has a v6 loopback address. More architecture cfg() fixes. These all need to be the same, and they were not. Make them them all the same. Attempt III. Fix up mismatched cfg's again. Take IV. Make sure the cfg's that use a enum variant match the enum definition.

2020-05-26Fix build on OpenBSD caused by erroneous inclusion in allowed OS list for ↵Nick Pelone
sendmmsg() / recvmmsg() in #1208. In #1208, sendmmsg() / recvmmsg() were added, but OpenBSD(who doesn't support these) was included on the list of allowed operating systems for sendmmsg() related things. This broke the build on OpenBSD. For more Rust-world examples, see: https://github.com/rust-lang/libc/commit/6f6297301d49ff67b8ca044d651f36a56950298c
2020-05-16Apply `repr(transparent)` to several FFI typesAlan Somers
repr(transparent) is required in order to safely cast between an FFI type and its NewType. This commit applies that attribute to PollFd, EpollEvent, IpMembershipRequest, Ipv6MembershipRequest, TimeVal, and IoVec. Fixes #1241

This eliminates one of the last remaining uninitialized memory accesses in Nix. Fixes #1142
2019-10-28Fix sys::socket::recvfrom for TCP socketsAlan Somers
recvfrom(2) only returns the sender's address for protocols that provide it. Usually, that means it returns the sender's address for datagram sockets but not for stream sockets. Fixes #1144
2019-10-15Properly initialize msghdr when using muslYuxuan Shui
Because of the use of MaybeUninit::uninit, the padding fields in msghdr, which only present on musl builds, are not initialized. Causing garbage data to be sent to the kernel. This change ensures the paddings are always zeroed.
2019-09-19Where relevant, replace equality checks in assert! with assert_eq!Xavier L'Heureux
`assert_eq!` gives more debug info when the test fails by default than `assert!`. This should help make debugging easier.
2019-09-03Replace most instances of mem::uninitialized with mem::MaybeUninitAlan Somers
Only two instances remain: * For the deprecated sys::socket::CmsgSpace::new. We should probably just remove that method. * For sys::termios::Termios::default_uninit. This will require some more thought. Fixes #1096

* Replace obsolete range syntax "..." with inclusive range "..=" * Use dyn Trait syntax instead of Box<Trait> * Raise MSRV to 1.27.0 (for dyn Trait syntax) * Raise MSRV to 1.31.0 (because of rand) tempfile pulls in rand, and rand pulls in fuchsia-cprng, which requires 1.31.0. Why rand pulls in fuchsia-cprng I don't know. It's specified as a target-specific dependency, but Cargo tries to build it anyway (only on Linux, not on FreeBSD or OSX). A bug in Cargo 1.27.0?

2019-02-14Fix misaligned references when using recvmsg with control messagesAlan Somers
On some platforms the alignment of cmsg_data could be less than the alignment of the messages that it contains. That led to unaligned reads on those platforms. This change fixes the issue by always copying the message contents into aligned objects. The change is not 100% backwards compatible when using recvmsg. Users may have to replace code like this: ```rust if let ControlMessage::ScmRights(&fds) = cmsg { ``` with this: ```rust if let ControlMessageOwned::ScmRights(fds) = cmsg { ``` Fixes #999
2019-02-14Replace CmsgSpace with a macroAlan Somers
CmsgSpace had three problems: 1) It would oversize buffers that expect multiple control messages 2) It didn't use the libc CMSG_SPACE(3) macro, so it might actually undersize a buffer for a single control message. 3) It could do bad things on drop, if you instantiate it with a type that implements Drop (which none of the currently supported ControlMessage types do). Fixes #994
2019-02-14Fix error handling of RecvMsgAlan Somers
There were two problems: 1) It would always return Ok, even on error 2) It could panic if there was an error, because sockaddr_storage_to_addr would be called on uninitialized memory.
2019-02-14Replace hand-rolled cmsg logic with libc's cmsg(3) functions.Alan Somers
Our hand-rolled logic had subtle alignment bugs that caused test_scm_rights to fail on OpenBSD (and probably could cause problems on other platforms too). Using cmsg(3) is much cleaner, shorter, and more portable. No user-visible changes.
