* NFS: Add dentry materialisation opDavid Howells2006-09-22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The attached patch adds a new directory cache management function that prepares a disconnected anonymous function to be connected into the dentry tree. The anonymous dentry is transferred the name and parentage from another dentry. The following changes were made in [try #2]: (*) d_materialise_dentry() now switches the parentage of the two nodes around correctly when one or other of them is self-referential. The following changes were made in [try #7]: (*) d_instantiate_unique() has had the interior part split out as function __d_instantiate_unique(). Callers of this latter function must be holding the appropriate locks. (*) _d_rehash() has been added as a wrapper around __d_rehash() to call it with the most obvious hash list (the one from the name). d_rehash() now calls _d_rehash(). (*) d_materialise_dentry() is now __d_materialise_dentry() and is static. (*) d_materialise_unique() added to perform the combination of d_find_alias(), d_materialise_dentry() and d_add_unique() that the NFS client was doing twice, all within a single dcache_lock critical section. This reduces the number of times two different spinlocks were being accessed. The following further changes were made: (*) Add the dentries onto their parents d_subdirs lists.

| | | | | | | | | | | The current access cache only allows one entry at a time to be cached for each inode. Add a per-inode red-black tree in order to allow more than one to be cached at a time.

For one it doesn't return a value to indicate success or failure, nor does it take a per-operation descriptor which is essential for the issuing of requests while other requests are still outstanding. This patch is the first in a series of steps to remodel the interface for asynchronous operations. For the ease of transition the new interface will be known as "hash" while the old one will remain as "digest". This patch also changes sg_next to allow chaining.

| * | | | [CRYPTO] cipher: Added block ciphers for CBC/ECBHerbert Xu2006-09-20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds two block cipher algorithms, CBC and ECB. These are implemented as templates on top of existing single-block cipher algorithms. They invoke the single-block cipher through the new encrypt_one/decrypt_one interface. This also optimises the in-place encryption and decryption to remove the cost of an IV copy each round. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
| * | | | [CRYPTO] cipher: Added block cipher typeHerbert Xu2006-09-20

Unlike current cipher algorithms which operate on a single block at a time, block ciphers operate on an arbitrarily long linear area of data. As it is block-based, it will skip any data remaining at the end which cannot form a block. The block cipher has one major difference when compared to the existing block cipher implementation. The sg walking is now performed by the algorithm rather than the cipher mid-layer. This is needed for drivers that directly support sg lists. It also improves performance for all algorithms as it reduces the total number of indirect calls by one. In future the existing cipher algorithm will be converted to only have a single-block interface. This will be done after all existing users have switched over to the new block cipher type.

| * | | | [CRYPTO] scatterwalk: Prepare for block ciphersHerbert Xu2006-09-20

Firstly it halves the size of scatter_walk on 32-bit platforms. This is important as we allocate at least two of these objects on the stack for each block cipher operation. It also exports the symbols since the block cipher code can be built as a module. Finally there is a hack in scatterwalk_unmap that relies on progress being made. Unfortunately, for hardware crypto we can't guarantee progress to be made since the hardware can fail. So this also gets rid of the hack by not advancing the address returned by scatterwalk_map.

This will be the main interface after the existing block operations have moved over to the new block ciphers. It also adds the crypto_cipher type which is currently only used on the new operations but will be extended to setkey as well once existing users have been converted to use block ciphers where applicable.

As a result of that, we check the types at run-time before each crypto operation. This is rather cumbersome. We could instead use different C types for each crypto type to ensure that the correct types are used at compile time. That is, we would have crypto_cipher/crypto_digest instead of just crypto_tfm. The appropriate type would then be required for the actual operations such as crypto_digest_digest. Now that we have the type/mask fields when looking up algorithms, it is easy to request for an algorithm of the precise type that the user wants. However, crypto_alloc_tfm currently does not expose these new attributes. This patch introduces the function crypto_alloc_base which will carry these new parameters. It will be renamed to crypto_alloc_tfm once all existing users have been converted. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

This patch also gets rid of a few unnecessary checks on the key length for ciphers as the cipher layer guarantees that the key length is within the bounds specified by the algorithm. Rather than testing dia_setkey every time, this patch does it only once during crypto_alloc_tfm. The redundant check from crypto_digest_setkey is also removed.

| * | | | [CRYPTO] api: Split out low-level APIHerbert Xu2006-09-20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The crypto API is made up of the part facing users such as IPsec and the low-level part which is used by cryptographic entities such as algorithms. This patch splits out the latter so that the two APIs are more clearly delineated. As a bonus the low-level API can now be modularised if all algorithms are built as modules.

| * | | | [IPSEC]: Move linux/crypto.h inclusion out of net/xfrm.hHerbert Xu2006-09-20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The header file linux/crypto.h is only needed by a few files so including it in net/xfrm.h (which is included by half of the networking stack) is a waste. This patch moves it out of net/xfrm.h and into the specific header files that actually need it. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
| * | | | [CRYPTO] api: Add crypto_alg reference countingHerbert Xu2006-09-20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Up until now we've relied on module reference counting to ensure that the crypto_alg structures don't disappear from under us. This was good enough as long as each crypto_alg came from exactly one module. However, with parameterised crypto algorithms a crypto_alg object may need two or more modules to operate. This means that we need to count the references to the crypto_alg object directly. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: David S. Miller <davem@davemloft.net>

It also creates a new header file which will be used by all 3 modules. This eliminates all code duplication. Correctness was verified with the tcrypt module and automated test scripts.
