      KEYS: Provide signature verification with an asymmetric key · 4ae71c1d
      由 David Howells 提交于 
      Provide signature verification using an asymmetric-type key to indicate the
public key to be used.

The API is a single function that can be found in crypto/public_key.h:

	int verify_signature(const struct key *key,
			     const struct public_key_signature *sig)

The first argument is the appropriate key to be used and the second argument
is the parsed signature data:

	struct public_key_signature {
		u8 *digest;
		u16 digest_size;
		enum pkey_hash_algo pkey_hash_algo : 8;
		union {
			MPI mpi[2];
			struct {
				MPI s;		/* m^d mod n */
			} rsa;
			struct {
				MPI r;
				MPI s;
			} dsa;
		};
	};

This should be filled in prior to calling the function.  The hash algorithm
should already have been called and the hash finalised and the output should
be in a buffer pointed to by the 'digest' member.

Any extra data to be added to the hash by the hash format (eg. PGP) should
have been added by the caller prior to finalising the hash.

It is assumed that the signature is made up of a number of MPI values.  If an
algorithm becomes available for which this is not the case, the above structure
will have to change.

It is also assumed that it will have been checked that the signature algorithm
matches the key algorithm.

This patch fixes this by providing a declaration for struct shash_desc.

      net: remove mm.h inclusion from netdevice.h · b7f080cf
      由 Alexey Dobriyan 提交于 
      Remove linux/mm.h inclusion from netdevice.h -- it's unused (I've checked manually).

To prevent mm.h inclusion via other channels also extract "enum dma_data_direction"
definition into separate header. This tiny piece is what gluing netdevice.h with mm.h
via "netdevice.h => dmaengine.h => dma-mapping.h => scatterlist.h => mm.h".
Removal of mm.h from scatterlist.h was tried and was found not feasible
on most archs, so the link was cutoff earlier.

Hope people are OK with tiny include file.

Note, that mm_types.h is still dragged in, but it is a separate story.

      crypto: af_alg - User-space interface for Crypto API · 03c8efc1
      由 Herbert Xu 提交于 
      This patch creates the backbone of the user-space interface for
the Crypto API, through a new socket family AF_ALG.

Each session corresponds to one or more connections obtained from
that socket.  The number depends on the number of inputs/outputs
of that particular type of operation.  For most types there will
be a s ingle connection/file descriptor that is used for both input
and output.  AEAD is one of the few that require two inputs.

Each algorithm type will provide its own implementation that plugs
into af_alg.  They're keyed using a string such as "skcipher" or
"hash".

IOW this patch only contains the boring bits that is required
to hold everything together.

Thakns to Miloslav Trmac for reviewing this and contributing
fixes and improvements.

      crypto: skcipher - Add ablkcipher_walk interfaces · bf06099d
      由 David S. Miller 提交于 
      These are akin to the blkcipher_walk helpers.

The main differences in the async variant are:

1) Only physical walking is supported.  We can't hold on to
   kmap mappings across the async operation to support virtual
   ablkcipher_walk operations anyways.

2) Bounce buffers used for async more need to be persistent and
   freed at a later point in time when the async op completes.
   Therefore we maintain a list of writeback buffers and require
   that the ablkcipher_walk user call the 'complete' operation
   so we can copy the bounce buffers out to the real buffers and
   free up the bounce buffer chunks.

These interfaces will be used by the new Niagara2 crypto driver.
