H A Dalgif_skcipher.cdiff bc97e57eb21f8db55bf0e1f182d384e75b2e3c99 Tue Nov 30 03:04:31 CST 2010 Herbert Xu <herbert@gondor.apana.org.au> crypto: algif_skcipher - Handle unaligned receive buffer

As it is if user-space passes through a receive buffer that's not
aligned to to the cipher block size, we'll end up encrypting or
decrypting a partial block which causes a spurious EINVAL to be
returned.

This patch fixes this by moving the partial block test after the
af_alg_make_sg call.
