From 4203223a1aed862b4445fdcd260d6139603a51d9 Mon Sep 17 00:00:00 2001 From: Tushar Gohad Date: Thu, 28 Jul 2011 10:36:20 +0000 Subject: xfrm: Fix key lengths for rfc3686(ctr(aes)) Fix the min and max bit lengths for AES-CTR (RFC3686) keys. The number of bits in key spec is the key length (128/256) plus 32 bits of nonce. This change takes care of the "Invalid key length" errors reported by setkey when specifying 288 bit keys for aes-ctr. Signed-off-by: Tushar Gohad Acked-by: Herbert Xu Signed-off-by: David S.
