An earlier version can also be found at https://lists.gnu.org/archive/html/grub-devel/2016-03/msg00298.html (March 30, 2016). The version the test suite uses for its "grub_202_patched" build is at https://github.com/charles-dyfis-net/grub-openpgp-compat-test/blob/master/pkgs/grub_2.02/openpgp-hashed-keyid-subpacket.patch, but since I did some repair to square it against the final grub 2.02 release it's not Ignat's original work. Any guidance you're willing to offer would be welcome -- I'm hoping to find a good chunk of time this weekend, but it's been ~20 years since I spent the bulk of my time in C, so there's been a bit of skillset atrophy; I'm trying to be slow and cautious. The next step I'm planning on taking is amending the test framework to automate attaching gdb to its test cases; with that done, I expect to be in a place to start walking through the existing code and making notes on how existing behavior squares with the RFC.
