On 01/07/11 10:40, Somebody in the thread at some point said:
It would appear that sha512sum is broken, at least in the F12 distro
(coreutils-7.6-5.fc12.fa1.armv5tel). It is producing a different hash
for the same file compared to what my x86 machines produce. This is
quite worrying and a potentially dangerous crypto-security issue.
The only thing that comes to mind as a potential cause (other than a
bug) is that I am using gcc/libgcc from F13 with F12 coreutils. I just
updated coreutils to the F13 package (coreutils-8.4-5.fc13.armv5tel),
and that produces the correct hashes.
Can anybody with a clean F12 vanilla copy check if they can reproduce
the problem?
No problem here.
