Description Ondrej Kozina 2013-11-25 18:08:57 UTC

Description of problem:

cryptsetup-reencrypt (just the utility) is not aware of non-512 sector size block devices

Version-Release number of selected component (if applicable):
cryptsetup-reencrypt-1.6.2-2.el7 (even upstream 1.6.2)

How reproducible:

Steps to Reproduce:
1. create 4K physical sector size block device (modprobe scsi_debug sector_size=4096 dev_size_mb=100) 
2. echo aaa | cryptsetup --force-password luksFormat /dev/sdd (/dev/sdd being 4K sector blockdev)
3. cryptsetup-reencrypt --debug /dev/sdd

Actual results:
cryptsetup-reencrypt fails w/ message "Cannot read /dev/sdd"

Expected results:
/dev/sdd is reencrypted

Comment 3 Ondrej Kozina 2013-11-26 12:36:19 UTC

Fix is already on it's way to upstream cryptsetup

Comment 5 Ondrej Kozina 2013-12-09 09:56:50 UTC

fixed in upstream: http://code.google.com/p/cryptsetup/source/detail?r=957201e7586f16f11106d7cde23289401d14d47b

(comment in git wrongly references different bug)
