Use explicitly specified ivsize instead of blocksize, when we mean IV size.

Authored by ae on Jan 12 2015, 5:52 PM.



In r275732 was introduced new field in struct enc_xform ivsize and all
xform definitions were modified by copying blocksize value into ivsize.
Some encryption algorithms can use different IV size and block size,
and in preparation for adding them ESP implementation needs a small modification.

Also set ivsize = 0 in enc_xform_null and remove special handling for them.

Test Plan

Currently it affects nothing. I tested IPsec between patched and unpatched
host - ESP still works.

Can you please not commit this.
I have a patch which does all of this and more, including using AES-NI for IPsec.

Well, there is now D2566, which I believe has parts of this change in it, but there is to be an updated patch soon too.
