From 114b0c799dd36080b91679d7c8cf49a295213919 Mon Sep 17 00:00:00 2001 From: David Carlier Date: Fri, 8 Dec 2023 12:00:37 +0000 Subject: [PATCH] std: enabling new netbsd (10) calls. Introducing a new config for this purpose as NetBSD 9 or 8 will be still around for a good while. For now, we re finally enabling sys::unix::rand::getrandom. --- library/std/build.rs | 4 +++- library/std/src/sys/pal/unix/rand.rs | 10 ++++++---- src/bootstrap/src/lib.rs | 1 + 3 files changed, 10 insertions(+), 5 deletions(-) diff --git a/library/std/build.rs b/library/std/build.rs index 35b183c47d7..ee3f3612d2e 100644 --- a/library/std/build.rs +++ b/library/std/build.rs @@ -7,7 +7,9 @@ fn main() { let target_vendor = env::var("CARGO_CFG_TARGET_VENDOR").expect("CARGO_CFG_TARGET_VENDOR was not set"); let target_env = env::var("CARGO_CFG_TARGET_ENV").expect("CARGO_CFG_TARGET_ENV was not set"); - + if target_os == "netbsd" && env::var("RUSTC_STD_NETBSD10").is_ok() { + println!("cargo:rustc-cfg=netbsd10"); + } if target_os == "linux" || target_os == "android" || target_os == "netbsd" diff --git a/library/std/src/sys/pal/unix/rand.rs b/library/std/src/sys/pal/unix/rand.rs index 1dba1ccf64e..5c32957bc51 100644 --- a/library/std/src/sys/pal/unix/rand.rs +++ b/library/std/src/sys/pal/unix/rand.rs @@ -62,7 +62,7 @@ fn getrandom( unsafe { getrandom(buf.as_mut_ptr().cast(), buf.len(), libc::GRND_NONBLOCK) } } - #[cfg(any(target_os = "espidf", target_os = "horizon", target_os = "freebsd"))] + #[cfg(any(target_os = "espidf", target_os = "horizon", target_os = "freebsd", netbsd10))] fn getrandom(buf: &mut [u8]) -> libc::ssize_t { unsafe { libc::getrandom(buf.as_mut_ptr().cast(), buf.len(), 0) } } @@ -72,7 +72,8 @@ fn getrandom(buf: &mut [u8]) -> libc::ssize_t { target_os = "android", target_os = "espidf", target_os = "horizon", - target_os = "freebsd" + target_os = "freebsd", + netbsd10 )))] fn getrandom_fill_bytes(_buf: &mut [u8]) -> bool { false @@ -83,7 +84,8 @@ fn getrandom_fill_bytes(_buf: &mut [u8]) -> bool { target_os = "android", target_os = "espidf", target_os = "horizon", - target_os = "freebsd" + target_os = "freebsd", + netbsd10 ))] fn getrandom_fill_bytes(v: &mut [u8]) -> bool { use crate::sync::atomic::{AtomicBool, Ordering}; @@ -230,7 +232,7 @@ pub fn fill_bytes(v: &mut [u8]) { } // FIXME: once the 10.x release becomes the minimum, this can be dropped for simplification. -#[cfg(target_os = "netbsd")] +#[cfg(all(target_os = "netbsd", not(netbsd10)))] mod imp { use crate::ptr; diff --git a/src/bootstrap/src/lib.rs b/src/bootstrap/src/lib.rs index 36f9ee6aff6..0e9a9791fb2 100644 --- a/src/bootstrap/src/lib.rs +++ b/src/bootstrap/src/lib.rs @@ -86,6 +86,7 @@ (Some(Mode::Std), "no_global_oom_handling", None), (Some(Mode::Std), "no_rc", None), (Some(Mode::Std), "no_sync", None), + (Some(Mode::Std), "netbsd10", None), (Some(Mode::Std), "backtrace_in_libstd", None), /* Extra values not defined in the built-in targets yet, but used in std */ (Some(Mode::Std), "target_env", Some(&["libnx"])),
