2022-11-19Fix using SockaddrStorage to store Unix domain addresses on LinuxAlan Somers
Since it has variable length, the user of a sockaddr_un must keep track of its true length. On the BSDs, this is handled by the builtin sun_len field. But on Linux-like operating systems it isn't. Fix this bug by explicitly tracking it for SockaddrStorage just like we already do for UnixAddr. Fixes #1866

It returns the mount flags on the BSDs. On Linux, it returns a slightly different set of flags.

2022-10-14reimplement recvmsg/sendmmsgMichael Baikov
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() }; ```
2022-10-14pack_mhdr_to_receive: pass iovec ptr and capacity separatelyMichael Baikov
We'll be using that to reinitialize buffers later
2022-10-14pack_mhdr_to_receive: pass pointer and capacity directlyMichael Baikov
This is already an unsafe function, dealing with pointers directly does not make it much more unsafe but simplifies lifetimes later on and similar to a previous commit allows to alocate a single buffer to store all the control messages
2022-10-14socket: stop setting vector length inside read_mhdrMichael Baikov
CMSG_FIRSTHDR/CMSG_NEXTHDR operate in terms of pointers contained inside msghdr structure, vector capacity doesn't matter for them. This would change external behavior of recvmsg/recvmmsg in a sense that buffer passed to store controll messages won't have it's length updated but intended way to receive control messages is with cmsgs iterator on `RecvMsg` which would still work. This change is required to allow using a single vector to store control messages from multiple packets

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!

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.
