From 26bab0ae9c65d08ef377e1c469155e4ef24dea09 Mon Sep 17 00:00:00 2001 From: Ray Walker Date: Fri, 15 May 2026 21:41:55 +1000 Subject: [PATCH 1/9] ci: fix EXDEV error in fuzz-smoke rustup nightly install Set RUSTUP_HOME=/tmp/rustup and CARGO_HOME=/tmp/cargo so rustup temp files and toolchains are on the same filesystem. Without this, `rustup toolchain install nightly` fails with "Invalid cross-device link (os error 18)" on ephemeral runners where /home/runner/.rustup (hostPath cache volume) and /tmp (overlay) are different mounts. Same fix applied to cachekit-rs CI in 2026-03. --- .github/workflows/fuzz-smoke.yml | 4 ++++ 1 file changed, 4 insertions(+) diff --git a/.github/workflows/fuzz-smoke.yml b/.github/workflows/fuzz-smoke.yml index 0e53896..4347c54 100644 --- a/.github/workflows/fuzz-smoke.yml +++ b/.github/workflows/fuzz-smoke.yml @@ -14,6 +14,10 @@ permissions: env: CARGO_TERM_COLOR: always RUST_BACKTRACE: 1 + # Avoid EXDEV "cross-device link" errors on ephemeral runners where + # hostPath cache and overlay are on different filesystems + RUSTUP_HOME: /tmp/rustup + CARGO_HOME: /tmp/cargo concurrency: group: ${{ github.workflow }}-${{ github.ref }} From 362d5f44f85fcd1b05ce4d47b84cafb5086ed98a Mon Sep 17 00:00:00 2001 From: Ray Walker Date: Fri, 15 May 2026 21:52:16 +1000 Subject: [PATCH 2/9] ci: pin fuzz-smoke to nightly-2026-05-10 (rustix vs nightly breakage) cargo-fuzz 0.13.1 depends on rustix which uses internal rustc_layout_scalar_valid_range_* attributes.
