Rollup merge of #129121 - devnexen:stabilize_ext_linux_tcp_layer, r=tgross35

2025-06-09T11:55:32+00:00

Stabilize `tcp_quickack` to stabilise the quickack part for now, tcp_deferaccept had been added at a later stage. The related API calls are the following ```rust // std::os::linux::net // sealed trait, implemented for std::net::TcpStream pub trait TcpStreamExt: Sealed{ fn quickack(&self) -> io::Result; fn set_quickack(&self, quickack: bool) -> io::Result<()>; } ``` Closes: https://github.com/rust-lang/rust/issues/96256

Update std doctests for android

2025-05-15T01:26:06+00:00

This updates some doctests that fail to run on android. We will soon be supporting cross-compiled doctests, and the `arm-android` job fails to run these tests. In summary: - Android re-exports some traits from linux under a different path. - Android doesn't seem to have common unix utilities like `true`, `false`, or `whoami`, so these are disabled.

proposal to expand (a subset of) linux specific socket capabilities.

Reformat `use` declarations.

The previous commit updated `rustfmt.toml` appropriately. This commit is the outcome of running `x fmt --all` with the new formatting options.

Convert `Unix{Datagram,Stream}::{set_}passcred()` to per-OS traits

2023-10-25T08:01:21+00:00

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.

os::net: expanding TcpStreamExt for Linux with `tcp_deferaccept`.

allows for socket to process only when there is data to process, the option sets a number of seconds until the data is ready.

Rollup merge of #106618 - jmillikin:os-net-rustdoc-wasm32, r=JohnTitor

2023-01-29T05:14:16+00:00

Disable `linux_ext` in wasm32 and fortanix rustdoc builds. The `std::os::unix` module is stubbed out when building docs for these target platforms. The introduction of Linux-specific extension traits caused `std::os::net` to depend on sub-modules of `std::os::unix`, which broke rustdoc for the `wasm32-unknown-unknown` target. Adding an additional `#[cfg]` guard solves that rustdoc failure by not declaring `linux_ext` on targets with a stubbed `std::os::unix`. Fixes #105467
