Compiling it in the kernel solves the problem. Thanks for the clue! I now have the xts(ecb(aes-generic)) driver appearing in /proc/crypto. I had no xts driver before. I don't think it's necessary now to copy my kernel config. Also, it's quite minimalist: make defconfig with a few drivers I need, mostly compiled in the kernel. > (See commit description, shouldn't XTS now select ECB as well?

Should I submit a patch for that? Or maybe it would be easier if a maintainer directly makes the change? > What mail on dmcrypt list? I do not see any recent mail. It was a mail from 2012, I should be more careful with search engines... -- Nicolas Porcel
