Hi, I have met a "Access denied " error, when run wasi-socket tests using wasm cmd. please help me to check what it's the reason.
Really appreciate it.

After build the artifacts under the test-programs,I got the .wasm file of the bin files under the test-programs(the .wasm file in my host under the dir /Wasmtime/target/debug/build/test-programs-artifacts-10901ff28f726621/out/wasm32-wasi/debug ). And then I execute the command:
~/work/Git/Wasmtime/target/debug/wasmtime run --wasm component-model preview2_udp_connect.component.wasm

And then, error happends:

And I found many files if it executing the blocking_bind() func, it would triggle this Error Code.
And I found it both in linux and macos.

alexcrichton commented on issue #7762:

Would you perhaps have ipv6 disabled on your machine? If that's not the case this'll probably need some more debugging prints added to the tests to understand why this is failing.

cc @badeend as well as you might have an idea too

badeend commented on issue #7762:

Nothing spings to mind. Like Alex said, it would be good to know whether this happens on a specific IP version or not. At the bottom of the test file you can comment out all Ipv6 invocations and see whether that changes anything, if not; maybe check with the Ipv4 tests commented out instead.

I've tried removing the ipv6 related test functions, but it comes out the same error

Greensue commented on issue #7762:

I fond the SocketAddrCheck func are false as default, and I change that to True , then the test passed. @badeend

impl Default for SocketAddrCheck {
    fn default() -> Self {
        Self(Arc::new(|_, _| false))
    }
}

Aha I see what's going on here, I missed this earlier. Yes running the binaries from the CLI by default will require the -Sinherit-network option to be specified. The CLI disables network access by default, and the tests assume network access. This is configured as part of the test runner by when running outside of the runner you'll need to configure network access to be available.
