Sorry in advance for making what shall be a basic question for this list, but I have really ran out of ideas. Can someone explain me please, how does the memory layout and sg lists work for the IPSec case, with generated IV case? As I understand, it is like this (ascii art) AD | IV Space | Plain Text | Auth Tag ^ ^ | | asg sg But I am having the AD overwritten, and the AUTH tag and encryption is not correct? Could someone please point me in the right direction? Thank you again Regards Juan -- To unsubscribe from this list: send the line "unsubscribe linux-crypto" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
