[macOS] OpenSSL 1.1 will be removed and OpenSSL 3 will be the default for all macOS images from November 4 #10817

Open sarathrajsrinivasan opened 3 weeks ago

sarathrajsrinivasan commented 3 weeks ago

Breaking changes

OpenSSL 1.1 will be removed from all macOS images and the default version will be switched to OpenSSL 3.

Target date

Image deployment will start on November 4 and will take 2-3 days.

The motivation for the changes

OpenSSL 1.1 has reached its end-of-life (EOL) and is no longer supported. Due to its deprecation, Homebrew has removed it from its available packages.

Possible impact

If your library/project is not compatible with OpenSSL 3 and you build them based on default OpenSSL version - your workflow will be broken.

Platforms affected

Runner images affected

Mitigation ways

Use the below step in your workflow to download and install OpenSSL 1.1 manually

    - name : Install  OpenSSL 1.1 manually
      run : |
        wget https://www.openssl.org/source/openssl-1.1.1w.tar.gz
        tar -xvf openssl-1.1.1w.tar.gz
        cd openssl-1.1.1w
        ./config --prefix=/usr/local/openssl
        make
        sudo make install
        export PATH=/usr/local/openssl/bin:$PATH

This means currently some runs on macos-14 have openssl@1.1 and some don't: https://github.com/eregon/setup-ruby/actions/runs/11724213556/job/32657603152

This is quite problematic because if something is built on macos-14 on a run with openssl@1.1 (and the software links to that) it can fail when that's later used in another run as openssl@1.1 /opt/homebrew/opt/openssl@1.1/lib/libssl.1.1.dylib is gone.

Basically, anything that ever linked to openssl@1.1 on macos-* will be broken by this change (until it's recompiled against openssl@3).

Is there a way to configure our build so we only run on the OpenSSL@3-equipped images? We can't add the -legacy flag we need for OpenSSL@3 (called within InstallAppleCertificate@2's pre-job) because it breaks when the build runs on an openssl@1.1.1-equipped image, and we can't manually install openssl@1.1.1 via a script because the call to openssl is in InstallAppleCertificate@2's pre-job.

We worked around it with InstallAppleCertificate@2 by putting two copies of the task in our pipeline - one with opensslPkcsArgs: -legacy and one without, and with continueWithError: true on both so the one that fails won't fail our build.

Could this change be breaking actions/setup-python on Mac?

In this test run https://github.com/Chia-Network/chia-blockchain/actions/runs/11745259139?pr=18844 with 30x each of macOS ARM/Intel and Python version 3.9/3.10/3.11/3.12, only 3.10 on Intel failed. The passing jobs were run on either 20241008.186 or 20241023.237. The failing jobs were on 20241107.313.

I think we might be seeing a combination of both #10817 and #10812. In your test run, Python 3.10 was found in the cache on macOS ARM64, so it passes. But if you land on an agent without Python 3.10 in the cache, it will try to download and install, but fails with the SSL error.

I'm facing the same problem and if rollout to openssl@3.0 all the InstallAppleCertificate@2 task will be broken. Even if I use a cert signed by openssl@3.0 there is still a problem:

InstallAppleCertificate@2 will generate one command:

security import /MSALCPPAppleBuildCertificate_fgh.p12 -P -A -t cert -f pkcs12 -k ***/ios_signing_temp.keychain

which requires the MSALCPPAppleBuildCertificate_fgh.p12 signed by openssl@1.1

Hi All,

We are currently reverting the change and keeping OpenSSL 1.1 in our images. It will be the default version for now. Will keep you posted with the updates.

dalemyers commented 2 days ago

@sarathrajsrinivasan Why was this reverted? After having spent time adjusting our flows to make it work with v3, we now need to undo that work, causing more disruption. This is likely the case for many others.

eregon commented 2 days ago

@dalemyers There is no need to undo that work, openssl@3 is available before & after that change.

dalemyers commented 2 days ago

@dalemyers There is no need to undo that work, openssl@3 is available before & after that change.

It is, but it's not the default, and various tasks expect one version or the other, so they need to be adjusted. Anything we control calling openssl directly is fine.
