Package: cryptsetup
Version: 2:1.1.0-2.1
Severity: normal
Tags: squeeze sid patch
cryptsetup isLuks [..] code-path does not initialize gcrypt library properly.
For example: This is luksDump is from a healthy volume,
which was created with ripemd160 as the selected message digest.
# cryptsetup luksDump /dev/loop1
LUKS header information for /dev/loop1
Version: 1
Cipher name: serpent
Cipher mode: xts-benbi
Hash spec: ripemd160 <---
Payload offset: 2056
MK bits: 256
MK digest: 47 cd 8a 78 ab [...]
MK salt: d6 a9 81 f2 d7 [...]
MK iterations: 20750
UUID: e4245[...]
Key Slot 0: ENABLED
Iterations: 83[...]
Salt: 5d [...]
Key material offset: 8
AF stripes: 4000
Key Slot 1: DISABLED
[...]
However, for the same volume isLuks failes with
# cryptsetup isLuks /dev/loop1
Requested LUKS hash ripemd160 is not supported.
-
This behavior is actually a feature of libgcrypt.
It prevents damage and misuse of the library.
But in my case (I made the mistake of making
a root partition with ripemd160...) it confused
The initramfs script /scripts/local-top/cryptsetup,
which then tried to call "cryptsetup create ..."
instead of "luksOpen".
