| Subject: [PATCH] xfrm: Fix key lengths for rfc3686(ctr(aes)) |
| |
| commit 4203223a1aed862b4445fdcd260d6139603a51d9 upstream. |
| |
| 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. |
