Quoting Linus Torvalds <[email protected]>:
Krzysztof, please try to cc the appropriate people/list.
I've added linux-crypto and the people who touched aesni-intel since
3.6, and am re-quoting the whole email (except for the continuation
oopses that won't be relevant)
It seems to crash on the very first instruction of _aesni_enc1,
which is just a
movaps (KEYP), KEY
where on x86-32, KEYP is %edi and KEY is %xmm2.
In the oops register dump, %edi is 0xf169fe64, which looks like a
valid kernel pointer (depending on amount of memory), but it looks
like the problem is that it's not 16-byte aligned.
I dunno. None of the asm code seems to have changed since 3.6 afaik,
so some calling code change triggers this? Guys, ideas?
Linus
Problem is that aesni_enc is asmlinkage and it's casted to non-asmlinkage
function pointer (when using XTS mode). Doesn't break on x86-64, but on
x86-32 however.. My bad, sorry.
I'll send patch soon.
