620 followers · 20767 posts · Server todon.euHello #systemd bubble! Does anyone know why `ukify genkey` generates a signing key/cert pair (AFAICT that corresponds to the #EFI #SecureBoot DB Key/Cert), and even references sd-boot's ability to enroll them, but sd-boot requires .auth files for KEK, PK and DB (I mean, it can't just invent them :'-D)?
So, the only way to do that is to either manually generate KEK, PK and then sign them with the DB key and generate the .auth files, or to let a tool like #sbctl or whatever generate them and try to feed those into ukify (which internally uses #sbsigntool). But both seem to be a bit more of a hassle than needed?

33 followers · 272 posts · Server macaw.socialYour average Operating System gets a lot of quality engineering time (code review, testing etc).
You know what gets none of that? Firmware aka BIOS. Cheapest bidder wins garbage dumpster fire untested code.
All that fancy #SecureBoot and #TPM and stuff? All bullshit. Nobody reviewed that code, nor tested that it actually works.

311 followers · 11727 posts · Server todon.euIt seems that #Windows #Update #KB5012170 updates the #SecureBoot DBX database to exclude some exploits. Unfortunately this may fail with 0x800f0992 on installation with incompatible firmwares. OVMF_CODE.secboot.fd for #QEMU/#KVM/#libvirt seems to be just that. Switch to the 4M-version of the firmware which has 4 Megabytes allocated instead of 2M to fix this.
