- Nikos handed over project maintainance to Phil Sutter.
- Several pending patches have been merged upstream so we removed
them from the recipe. The remaining ones have been sorted

+ offload
-Upstream-status: Pending
+This adds support for composite algorithm offload as a primitive
+crypto (cipher + hmac) operation.
-This adds support for composite algorithm offload in a single crypto
-(cipher + hmac) operation.
-
-It requires either software or hardware TLS support in the Linux kernel
-and can be used with Freescale B*, P* and T* platforms that have support
-for hardware TLS acceleration.
+It requires kernel support for tls10(hmac(sha1),cbc(aes)) algorithm
+provided either in software or accelerated by hardware such as
+Freescale B*, P* and T* platforms.

-Without this patch, the hmac and cipher keys can't be combined in the

-Blockcipher and non-composite aead algorithms (e.g. AES-GCM) use a

-
-Upstream-status: Pending
-
-For in-place operations, the scatterlist must be big enough to allow for
-either the source or destination data:
- - for block ciphers, the destination will be bigger than the source if
- the source is not multiple of blocksize
- - for aead ciphers, the additional data and padding guarantees the
- destination to be bigger than the source.

- userspace
-
-Upstream-status: Pending
-
-There is no need to keep keys around for the entire duration of the
-session. The keys are copied from user-space and then used to initialize
-the ciphers. After this, the original keys can be discarded.
-The total required space for keys is small and known in advance. This
-patch uses this information to allocate required space on stack.
