2022-12-14Rework vsock testStefano Garzarella
We mainly provide VsockAddr, so let's try to test well that VsockAddr mapping to libc::sockaddr_vm is correct. Let's remove all interactions with the socket, since vsock may or may not be available in the environment. Testing socket(), bind(), listen(), connect(), etc. caused unexpected failures, and it's out of scope of this crate. So let's simplify the vsock test focussing on VsockAddr. This should work also on graviton, so let's try to re-enable it. Fixes #1934 Signed-off-by: Stefano Garzarella <sgarzare@redhat.com>

1913: feat: I/O safety for 'sys/inotify' r=asomers a=SteveLauC #### What this PR does: 1. Changes the `fd` field of `struct Inotify` from `RawFd` to `OwnedFd` 2. Changes the interfaces of functions in the `impl Inotify {}` > The type of `self` changes from `Self` to `&mut Self`. From: ```rust pub fn add_watch<P: ?Sized + NixPath>( self, path: &P, mask: AddWatchFlags, ) -> Result<WatchDescriptor> pub fn rm_watch(self, wd: WatchDescriptor) -> Result<()> pub fn read_events(self) -> Result<Vec<InotifyEvent>> ``` To: ```rust pub fn add_watch<P: ?Sized + NixPath>( &mut self, path: &P, mask: AddWatchFlags, ) -> Result<WatchDescriptor> pub fn rm_watch(&mut self, wd: WatchDescriptor) -> Result<()> pub fn read_events(&mut self) -> Result<Vec<InotifyEvent>> ``` In the previous implementation, these functions can take `self` by value as `struct Inotify` [was `Copy`](https://docs.rs/nix/latest/nix/sys/inotify/struct.Inotify.html#impl-Copy-for-Inotify). With the changes in `1` applied, `struct Inotify` is no longer `Copy`, so we have to take `self` by reference. ------- Blocks until the merge of #1863 as this PR needs `read(2)` to be I/O-safe. 1926: feat: I/O safety for 'sys/sendfile' r=asomers a=SteveLauC #### What this PR does: 1. Adds I/O safety for module `sys/sendfile`. 1927: feat: I/O safety for 'sys/statvfs' r=asomers a=SteveLauC #### What this PR does: 1. Adds I/O safety for module `sys/statvfs`. 1931: feat: I/O safety for 'sys/uid' & 'sched' r=asomers a=SteveLauC #### What this PR does: Adds I/O safety for modules: 1. `sys/uio` 2. `sched` 1933: feat: I/O safety for 'sys/timerfd' r=asomers a=SteveLauC #### What this PR does: 1.

2022-11-28Fix UB in the SO_TYPE sockoptAlan Somers
When reading a value into an enum from getsockopt, we must validate it. Failing to do so can lead to UB for example with SOCK_PACKET on Linux. Perform the validation in GetSockOpt::get. Currently SockType is the only type that requires validation. Fixes #1819

1857: Add better support for unnamed unix socket addrs r=asomers a=stevenengler This adds the following 2 functions/methods: `UnixAddr::new_unnamed` and `UnixAddr::is_unnamed`. Closes #1585 unix(7) on Linux: > unnamed: A stream socket that has not been bound to a pathname using bind(2) has no name. Likewise, the two sockets created by socketpair(2) are unnamed. When the address of an unnamed socket is returned, its length is `sizeof(sa_family_t)`, and `sun_path` should not be inspected. **Edit:** This currently isn't working on BSD, but I see why. Will fix it shortly. Co-authored-by: Steven Engler <opara@cs.georgetown.edu>

New implementation performs no allocations after all the necessary structures are created, removes potentially unsound code that was used by the old version (see below) and adds a bit more documentation about bugs in how timeout is actually handled ``` let timeout = if let Some(mut t) = timeout { t.as_mut() as *mut libc::timespec } else { ptr::null_mut() }; ```

2022-10-08Fix clippy warnings on nightlyRyan Zoeller
Clippy is now smarter about detecting unnecessary casts and useless conversions, which means we need to be more explicit about when the conversions are needed for a subset of platforms. Required changes found by repeatedly running the following command against a list of the supported platforms. `xargs -t -I {} sh -c "cargo clippy -Zbuild-std --target {} --all-targets -- -D warnings || exit 255"` I removed the casts it complained about, and then restored them with an `#[allow]` if a later target needed the cast.

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!
