Subject: [PATCH 0/3] MODVERSIONS + RUST Redux
Date: Wed, 15 Nov 2023 18:50:08 +0000 [thread overview]
Message-ID: <20231115185858.2110875-1-mmaurer@google.com> (raw)
Support both MODVERSIONS and RUST by making symbol version information extensible. This works by having a separate section per field, and allowing iteration to work differently per field. The old module information remains available to allow existing kmod tools to continue to work on new modules if they are only looking for C information.
This also gives us the ability to attach additional information to symbol versioning (e.g. namespacing) should it become necessary in the future without breaking backwards compatibility - new sections will be added, but existing tools will still find all their information and keep the existing format.
PPC has a hack around removing leading dots in symvers. I have
replicated this hack for the new format, but without context for why
this was being done, I can't test that it works as expected.
This was inspired by Masahiro Yamada's suggestion[1] when discussing the previous attempt.
