We've been 'lucky' so far that there's no file collision because linux-firmware provides compressed blobs and amd64-microcode doesn't. But that also means that the compressed blobs (from the wrong package) are used. [Fix] Don't ship AMD TEE firmware with linux-firmware. [Test Case] Inspect package content and verify that it doesn't provide /usr/lib/amdtee firmware. [Where Problems Could Occur] initramfs could contain wrong amdtee firmware and kernel could load wrong firmware. This can result in the usual kernel firmware problems: Unpatched issues due to wrong firmware loaded, kernel crashes, oops, hangs, ... [Original Description] Hi, the amdtee firmwares are provided both by amd64-microcode: $ dpkg -L amd64-microcode | grep amdtee /usr/lib/firmware/amdtee /usr/lib/firmware/amdtee/773bd96f-b83f-4d52-b12dc529b13d8543.bin /usr/lib/firmware/amdtee/amd_pmf_v3.bin and by linux-firmware: $ dpkg -L linux-firmware | grep amdtee /lib/firmware/amdtee /lib/firmware/amdtee/773bd96f-b83f-4d52-b12dc529b13d8543.bin.zst /lib/firmware/amdtee/amd_pmf_v3.bin.zst - one compressed and the other uncompressed - one in /lib and the other in /usr/lib Would it be possible to better coordinate both packages?
