[pkg-cryptsetup-devel] Bug#676159: cryptsetup checks LUKS offset incorrectly with detached header

[Alex Roper]

Package: cryptsetup
Version: 2:1.4.1-3
Severity: normal
Tags:

When operating with a detached header,
setup.c:crypt_check_data_device_size checks to make sure the detached
header is at least as large as the offset specified in the header. This
is fine for a regular header, but this causes a detached header to fail
unless the header file appears to be at least as large as the offset.

When --header is used, the check should consider the size of the backing
device, not the LUKS header device.
