ci: force reinstall of kernel headers in asan
When using hosted runners in combination with cached docker images,
there is the possibility that the host runner image is updated,
rendering the linux-headers package (stored in the cached docker image)
incompatible.
Fix this by doing a re-install of the headers package in
03_test_script.sh.
If the underlying runner kernel has not changed thie has no effect, but
prevents the job from failing if it has.
What changed, and why it matters
This commit changes a Bitcoin Core continuous integration (CI) test script. It forces a re-install of Linux kernel headers when running an AddressSanitizer (ASan) test in a Docker container. The goal is to avoid CI failures when the host runner's Linux kernel is updated but a cached Docker image still contains older kernel headers. This is a build/test infrastructure fix, not a change to the Bitcoin software users run.
No security action required. This is a CI reliability improvement. Reviewers may verify that apt-get install uses only the intended $PACKAGES list and that the change does not introduce unintended package upgrades.
Security signals we found
No strong security signals were identified.
Evidence from the diff
The patch adds a conditional block in ci/test/03_test_script.sh for the ci_native_asan container. It runs apt-get update and apt-get install for the packages listed in $PACKAGES, using the CI retry wrapper. The intent is to ensure the container’s linux-headers package matches the host kernel, preventing ASan CI jobs from failing due to kernel header mismatches on cached Docker images. No Bitcoin node code, consensus logic, networking, wallet, or RPC code is modified.
