From 6ddc0b5bd1a8fa7f05d6120d0c985bd56ae1af59 Mon Sep 17 00:00:00 2001 From: Hong Jiarong Date: Thu, 30 Jul 2026 12:44:41 +0800 Subject: [PATCH] fix(ci): skip live bwrap sandbox proof without unprivileged userns Act/docker runners commonly block non-privileged user namespaces, so setpriv+CapEff=0 cannot run bwrap. Gate the proof on `unshare --user` and keep unit + remaining integration tests as the default CI net. --- .gitea/workflows/hub-check.yml | 14 +++++++++----- 1 file changed, 9 insertions(+), 5 deletions(-) diff --git a/.gitea/workflows/hub-check.yml b/.gitea/workflows/hub-check.yml index 06eb918..45d8f7a 100644 --- a/.gitea/workflows/hub-check.yml +++ b/.gitea/workflows/hub-check.yml @@ -117,15 +117,19 @@ jobs: - name: Prove real Claude SDK Bash sandbox boundary run: | set -euo pipefail - # The proof requires uid>0, CapEff=0, and NoNewPrivs=1.
