[pbs-devel] [PATCH backup v2 0/2] fix #5946: disks: wipe: ensure GPT header backup is wiped

[Filip Schauer <f.schauer@proxmox.com>]

When wiping a block device with a GUID partition table, the header
backup might get left behind at the end of the disk. This commit also
wipes the last 4096 bytes of the disk, making sure that a GPT header
backup is erased, even from disks with 4k sector sizes.

Also lower the number of bytes that is zeroed out at the start of the
disk from 200 MiB to 1 MiB.

Changed since v1:
* Use `std::os::unix::fs::FileExt::write_all_at` instead of calling `dd`
* only zero out the first 1 MiB

Filip Schauer (2):
  fix #5946: disks: wipe: ensure GPT header backup is wiped
  disks: wipe: only zero out the first 1 MiB
