So a CRC calculated on a BE machine would fail to be validated by a
LE machine and vice versa.
Has this been fixed / verified?
From taking a look at crypto/crc32c.c it still appears AFAICT to not be
big endian safe. I was planning to test this patch on some powerpc/ppc
hardware with v2.6.36-rc4 in the next days, but it looks like
lio-core-2.6.git will need a seperate crypto/crc32c.c patch to function
properly on big endian arches.
There was this bug that was fixed a couple years ago:
http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff;h=ef19454bd437b2ba14c9cda1de85debd9f383484
since then I think we have not had problems.
