[pkg-cryptsetup-devel] Bug#949336: Mapped integrity devices of size ≥2TiB are unusable on 32-bits platforms

[nbf at waifu.club]

Package: cryptsetup-bin
Version: 2:2.1.0-5+deb10u2
Severity: important

Dear Maintainers,

this is an unfortunate folowup to #935702. I thank Milan Broz very much 
for fixing that one so quickly.

Unfortunately, even though the mapped size is now correct, 
integritysetup still silently configures a DM device that cannot be read 
and only gives I/O errors. Most likely this is another issue specific to 
large volumes on 32-bit systems.

Affected versions:
"testing" 2:2.2.2-1
"stable"  2:2.1.0-5+deb10u2

Working version:
same as in #935702

Affected command:
integritysetup --integrity hmac-sha256 --integrity-key-size=4096 
--integrity-key-file=/IDISK.ikey open /dev/sda IDISK


Best,
n.b.f.
