We looked at Stuart and it can prevent a recursive submodule update at the first level but then it would prevent further updates. Here Repo A can prevent a recursive update in edk2 but it would then not be able to get libspdm.

  [Repo A] -[1]> [edk2] -[2]> [libspdm] -[3]> [cmocka]

At its root, the issue is that this is broken, not wasteful. Therefore, it is disruptive and a regression for existing workflows.

We, and I'm sure many other projects, recursively clone packages in edk2 with submodules. For years, this has been fine except for a few brief exceptions. We pulled the change with the libspdm dependency into our codebase 8 days ago and this has been broken all day. The track record of cryptomilk.org in the past was also very poor and frequently caused problems. There is not an incident response team that I'm aware of at cryptomilk.org that provides status updates and proactively addresses services issues (i.e. https://www.githubstatus.com/).

Also, libspdm is now a dependency and cloning cmocka there may fail. Users should expect that they can clone and work in that repo as part of their firmware development process without frequent service disruptions in the way.

While I started this thread to raise the issue for users impacted here, I filed https://github.com/DMTF/libspdm/issues/2707 to track the request in the libspdm repo.

Thanks,
Michael

Libspdm also depends on openssl.  We did not want to clone openssl twice.

I though stuart config specifies which submodules to clone.  Can’t we skip
all the submodules within libspdm to fix CI?

Can't devs choose to not use --recursive?

I don't think that's a very good solution given the diversity of
downstream projects dependent on the repo or even for the libspdm repo
itself.

Thanks,

Subject: libspdm Breaking Builds

Recently, the libspdm submodule was added to SecurityPkg
(SecurityPkg/DeviceSecurity/SpdmLib/libspdm) [1].

That submodule points to https://github.com/DMTF/libspdm.git.

The libspdm repo contains a submodule for cmocka that is hosted on
cryptomilk.org [2].

Cloning that submodule is failing today, breaking all builds/CI
dependent on SecurityPkg.

This has been an issue in the past and it is very disruptive given the
number of dependencies on edk2/SecurityPkg. Because of its reliability
issues, edk2 moved to a version of the repo hosted in tianocore [3] in
2021 [4]

Can you please make a similar change in libspdm and we get edk2 updated
as soon as possible?

Thanks,
Michael
