[PATCH 03/17] cryptodisk: Incorrect calculation of start sector for grub_disk_read in grub_cryptodisk_read.

From: Glenn Washburn Here dev is a grub_cryptodisk_t and dev->offset is offset in sectors of size native to the cryptodisk device. The sector is correctly transformed into native grub sector size, but then added to dev->offset which is not transformed. It would be nice if the type system would he

[PATCH 06/17] luks2: grub_cryptodisk_t->total_length is the max number of device native sectors.

From: Glenn Washburn The total_length field is named confusingly because length usually refers to bytes, whereas in this case its really the total number of sectors on the device. Also counter-intuitively, grub_disk_get_size returns the total number of device native sectors sectors. We need to co

[PATCH 10/17] cryptodisk: Properly handle non-512 byte sized sectors.

From: Glenn Washburn By default, dm-crypt internally uses an IV that corresponds to 512-byte sectors, even when a larger sector size is specified. What this means is that when using a larger sector size, the IV is incremented every sector. However, the amount the IV is incremented is the number o

[PATCH 12/17] fs: Allow number of blocks in block list to be optional, where length will be defaulted to the length of the device.

From: Glenn Washburn This is primarily useful to do something like "loopback newdev (dev)8+" to create a device that skips the first 4K, which may contain a non-standard RAID1 header that grub does not recognize. This would allow that initial data to be accessed and potentially mounted by grub up
