#HFSPlus
Those HFSPlus drivers are what I installed after I guessed it was a Mac format drive.

But that AppleHFS driver ... that's been there for a loooooong time.

Slava started with a simple fuzzer implementation and then improved it step-by-step by adding coverage collection, proper seed generation, mutations, etc.

The source code of the fuzzer is public.

Streamlining secure boot for 26.10
Ubuntu systems support secure boot using grub. grub contains a lot of parsers for file systems and other things which are a constant source of security issues. In 26.10, we’d like to propose removing the following features from signed GRUB builds: Filesystems for /boot Remove btrfs, hfsplus, xfs, zfs Retain ext4, fat, iso9660 (and squashfs for snaps) Image formats: Remove jpeg, png Retain none We do not use images, but using that in your grub.cfg locally is a massive security risk (if eve...

Canonical named Ubuntu 26.10 "Stonking Stingray" for October 15 and proposed dropping btrfs, hfsplus, xfs, zfs from signed GRUB (the bootloader used for Secure Boot). Only ext4, FAT, ISO9660, squashfs stay. The people cutting the surface never pay for the migration.
