From 93f2f2c8ee44a8cb469fd7e656599c2b9546a1af Mon Sep 17 00:00:00 2001 From: John Millikin Date: Wed, 25 Oct 2023 17:01:21 +0900 Subject: Convert `Unix{Datagram,Stream}::{set_}passcred()` to per-OS traits These methods are the pre-stabilized API for obtaining peer credentials from an `AF_UNIX` socket, part of the `unix_socket_ancillary_data` feature. Their current behavior is to get/set one of the `SO_PASSCRED` (Linux), `LOCAL_CREDS_PERSISTENT` (FreeBSD), or `LOCAL_CREDS` (NetBSD) socket options. On other targets the `{set_}passcred()` methods do not exist. There are two problems with this approach: 1. Having public methods only exist for certain targets isn't permitted in a stable `std` API. 2. These options have generally similar purposes, but they are non-POSIX and their details can differ in subtle and surprising ways (such as whether they continue to be set after the next call to `recvmsg()`). Splitting into OS-specific extension traits is the preferred solution to both problems. --- library/std/src/os/linux/net.rs | 3 +++ 1 file changed, 3 insertions(+) (limited to 'library/std/src/os/linux') diff --git a/library/std/src/os/linux/net.rs b/library/std/src/os/linux/net.rs index c8e734d740b..f898e705487 100644 --- a/library/std/src/os/linux/net.rs +++ b/library/std/src/os/linux/net.rs @@ -5,5 +5,8 @@ #[stable(feature = "unix_socket_abstract", since = "1.70.0")] pub use crate::os::net::linux_ext::addr::SocketAddrExt; +#[unstable(feature = "unix_socket_ancillary_data", issue = "76915")] +pub use crate::os::net::linux_ext::socket::UnixSocketExt; + #[unstable(feature = "tcp_quickack", issue = "96256")] pub use crate::os::net::linux_ext::tcp::TcpStreamExt; -- cgit 1.4.1-3-g733a5
