Description Oliver Paukstadt 2005-06-15 04:09:59 EDT
Description of problem:
There is a bug in sha-hmac implementation.
This makes it impossible to exchange filesystem images between 64 and 32 bit
architectures.
Maybe this has an impact on security of encryption on 64 bit.

Version-Release number of selected component (if applicable):
cryptsetup-luks-1.0-1.src.rpm

How reproducible:
create an filesystem-image with luks on 32 bit and transfer it to 64 bit.
Same if you want to use the same partion from a 32/64 Bit dualboot.

Additional info:
Patch is available and attached

Note that some minor fixes need made here for it to build:

- s/uint32_t/u_int32_t/
- add a #include <sys/types.h>
