crypto: hash - Fixed digest size check
missed one spot for the digest type. This patch corrects that
error.Signed-off-by: Herbert Xu

All new crypto interfaces should go into individual files as much
as possible in order to ensure that crypto.h does not collapse under
its own weight.This patch moves the ahash code into crypto/hash.h and crypto/internal/hash.h
respectively.Signed-off-by: Herbert Xu

The base field in ahash_tfm appears to have been cut-n-pasted from
ablkcipher. It isn't needed here at all. Similarly, the info field
in ahash_request also appears to have originated from its cipher
counter-part and is vestigial.Signed-off-by: Herbert Xu

The digest size check on hash algorithms is incorrect. It's
perfectly valid for hash algorithms to have a digest length
longer than their block size. For example crc32c has a block
size of 1 and a digest size of 4. Rather than having it lie
about its block size, this patch fixes the checks to do what
they really should which is to bound the digest size so that
code placing the digest on the stack continue to work.HMAC however still needs to check this as it's only defined
for such algorithms.Signed-off-by: Herbert Xu

Every file should include the headers containing the externs for its
global code (in this case for struct crypto_{init,exit}_digest_ops()).Signed-off-by: Adrian Bunk

Unfortunately the generic chaining hasn't been ported to all architectures
yet, and notably not s390. So this patch restores the chainging that we've
been using previously which does work everywhere.Signed-off-by: Herbert Xu
-
The scatterwalk infrastructure is used by algorithms so it needs to
move out of crypto for future users that may live in drivers/crypto
or asm/*/crypto.Signed-off-by: Herbert Xu

This patch converts the crypto scatterwalk code to use the generic
scatterlist chaining rather the version specific to crypto.Signed-off-by: Herbert Xu

This patch removes the old cipher interface and related code.

Using blkcipher/hash crypto operations in hard IRQ context can lead
to random memory corruption due to the reuse of kmap_atomic slots.
Since crypto operations were never meant to be used in hard IRQ
contexts, this patch checks for such usage and returns an error
before kmap_atomic is performed.Signed-off-by: Herbert Xu

This patch removes the old HMAC implementation now that nobody uses it
anymore.Signed-off-by: Herbert Xu
Signed-off-by: David S. Miller -
The existing digest user interface is inadequate for support asynchronous
operations. 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.

The sleeping flag used to determine whether crypto_yield can actually
yield is really a per-operation flag rather than a per-tfm flag. This
patch changes crypto_yield to take a flag directly so that we can start
using a per-operation flag instead the tfm flag.Signed-off-by: Herbert Xu
-
When the final result location is unaligned, we store the digest in a
temporary buffer before copying it to the final location. Currently
that buffer sits on the stack. This patch moves it to an area in the
tfm, just like the CBC IV buffer.Signed-off-by: Herbert Xu
-
Now that the tfm is passed directly to setkey instead of the ctx, we no
longer need to pass the &tfm->crt_flags pointer.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.Signed-off-by: Herbert Xu

Fix a few omissions in passing TFM instead of CTX to algorithms.
Signed-off-by: Michal Ludvig
Signed-off-by: Herbert Xu -
Up until now algorithms have been happy to get a context pointer since
they know everything that's in the tfm already (e.g., alignment, block
size).However, once we have parameterised algorithms, such information will
be specific to each tfm. So the algorithm API needs to be changed to
pass the tfm structure instead of the context pointer.This patch is basically a text substitution. The only tricky bit is
the assembly routines that need to get the context pointer offset
through asm-offsets.h.Signed-off-by: Herbert Xu

Some hash modules load/store data words directly. The digest layer
should pass properly aligned buffer to update()/final() method. This

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.Let it rip!
