TCP_KEEPALIVE and LOCAL_PEEREID missing for QNX 8.0 (aarch64-unknown-nto-qnx800)

[AutumnYX]

TCP_KEEPALIVE and LOCAL_PEEREID are defined in the nto70/nto71 branch of src/unix/nto/mod.rs (lines 919 and 967), but missing from the else branch that covers nto80 (QNX 8.0). This causes compilation failures for crates like
socket2 and tokio when targeting aarch64-unknown-nto-qnx800.

Target triple: aarch64-unknown-nto-qnx800

Minimum reproduction:

// main.rs — no dependencies other than libc
extern crate libc;

fn main() {
let _ = libc::TCP_KEEPALIVE; // error[E0432]: no TCP_KEEPALIVE in the root
let _ = libc::LOCAL_PEEREID; // error[E0432]: no LOCAL_PEEREID in the root
}

Cargo.toml

[package]
name = "libc-qnx800-repro"
version = "0.1.0"
edition = "2021"

[dependencies]
libc = "0.2.185"

cargo build --target aarch64-unknown-nto-qnx800

Build log (trimmed):

error[E0432]: unresolved import libc::TCP_KEEPALIVE
--> /root/.cargo/registry/src/index.crates.io-.../socket2-0.5.10/src/sys/unix.rs:291:5
|
291 | use libc::TCP_KEEPALIVE as KEEPALIVE_TIME;
| ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ no TCP_KEEPALIVE in the root

error[E0432]: unresolved import libc::LOCAL_PEEREID
--> /root/.cargo/registry/src/index.crates.io-.../tokio-1.42.1/src/net/unix/ucred.rs:127:56

127 | use libc::{c_void, getsockopt, socklen_t, unpcbid, LOCAL_PEEREID, SOL_SOCKET};
| ^^^^^^^^^^^^^ no LOCAL_PEEREID in the root

Root cause:

In src/unix/nto/mod.rs, the cfg_if! block at line 906 splits QNX definitions into two branches:

• nto70 / nto71 (line 907): defines TCP_KEEPALIVE and LOCAL_PEEREID
• else — covering nto71_iosock and nto80 (line 982): does not define them

QNX 8.0 supports both constants. They should be added to the else branch.

Environment:

• libc: 0.2.185
• rustc: nightly (cross-compiling to aarch64-unknown-nto-qnx800)
• Host: x86_64-unknown-linux-gnu
• QNX SDP: 8.0

Do you know/have a reference for these values? Are these same as QNX 7.0/7.1? I cannot confirm it on my end as the source is not public.
