Re: Suspect bug in the authenc module

Hello

i pulled the crypto-2.6 repo today. Issues appear to be solved for both 32-bit 
and 64-bit systems. Many thanks!

I have got another trouble when compiling my test module with a 64-bit 
operating system:

when dumping the data placed pointed by the scatterlist array i noted that the 
assoc is always zero'ed. I investigated further and it seems that the problem 
is the static allocation of the assoc string in my test module. When using the 
kmalloc the dump is correct.
