Bump go

[acul71]

Updates / supersedes #788. Same bump-go changes but from my fork so the latest commit (fix: make go new transport spec compliant) is included.

Hi @MarcoPolo @dhuseby

I've upgrade go-v0.47 to the new transport specs. here I included the patch file.

I've opened a PR in go libp2p/go-libp2p#3456 but I'm having difficulties to make local CI/CD transport integration.

Here in test-plans all test passes except for

  ✗ 1 test(s) failed

The test is failing because of a WebRTC SRTP key length mismatch between Go and Rust, not because of your transport-spec or harness changes.

What happens

1. Rust listener panics in the SRTP (encryption) layer:

   • Assertion: left: 32 vs right: 16 in webrtc_srtp::key_derivation::aes_cm_key_derivation
   • So the Rust webrtc_srtp code expects a 16-byte key (AES-128-GCM) but gets 32 bytes (what Go is sending).

2. Go dialer then fails with “Failed to connect to other peer” because the Rust side has already crashed.

Why

• Go’s WebRTC stack is deriving/sending a 32-byte SRTP key (e.g. for AES-256-GCM or a different key format).
• Rust’s webrtc_srtp (and its use of generic-array in CipherAeadAesGcm::new) is built for a 16-byte key (AES-128-GCM).
• So the two stacks disagree on key size during DTLS/SRTP setup; this is an interop bug between go-libp2p and rust-libp2p WebRTC, not a bug in your test configuration.

What you can do

• Ignore this combo in CI: e.g. keep using --test-ignore "~failing" if go-v0.47-pre x rust-v0.56 (webrtc-direct) is already in the “failing” set, or add it so this test is skipped until the implementations are fixed.
• Fix the implementations: align Go and Rust WebRTC stacks on SRTP key length and cipher (e.g. both use 16-byte keys for AES-128-GCM, or both support the same 32-byte setup) in the respective libp2p/WebRTC repos.

So: the test is failing because of a known Go ↔ Rust WebRTC SRTP key-size mismatch, not because of your recent changes.
