This patch allows shash algorithms to be used through the old hash
interface. This is a transitional measure so we can convert the
underlying algorithms to shash before converting the users across.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

When HMAC gets a key longer than the block size of the hash, it needs
to feed it as input to the hash to reduce it to a fixed length. As
it is HMAC converts the key to a scatter and gather list. However,
this doesn't work on certain platforms if the key is not allocated
via kmalloc. For example, the keys from tcrypt are stored in the
rodata section and this causes it to fail with HMAC on x86-64.This patch fixes this by copying the key to memory obtained via
kmalloc before hashing it.Signed-off-by: Herbert Xu

Convert instances of ERR_PTR(PTR_ERR(p)) to ERR_CAST(p) using:
perl -spi -e 's/ERR_PTR[(]PTR_ERR[(](.*)[)][)]/ERR_CAST(\1)/' `grep -rl 'ERR_PTR[(]*PTR_ERR' fs crypto net security`

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

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

hmac_setkey(), hmac_init(), and hmac_final() have
a singular on-stack scatterlist. Initialit is
using sg_init_one() instead of using sg_set_buf().Signed-off-by: David S. Miller

Most drivers need to set length and offset as well, so may as well fold
those three lines into one.Add sg_assign_page() for those two locations that only needed to set
the page, where the offset/length is set outside of the function context.Signed-off-by: Jens Axboe

This patch passes the type/mask along when constructing instances of
templates. This is in preparation for templates that may support
multiple types of instances depending on what is requested. For example,
the planned software async crypto driver will use this construct.For the moment this allows us to check whether the instance constructed
is of the correct type and avoid returning success if the type does not
match.Signed-off-by: Herbert Xu

The error return values are truncated by unlikely so we need to

The crypto_hash_update call in hmac_init gave the number 1
instead of the length of the sg list in bytes. This is a
missed conversion from the digest => hash change.As tcrypt only tests crypto_hash_digest it didn't catch this.

anymore.Signed-off-by: Herbert Xu

This patch rewrites HMAC as a crypto template. This means that HMAC is no
longer a hard-coded part of the API. It's now a template that generates
standard digest algorithms like any other.The old HMAC is preserved until all current users are converted.
The same structure can be used by other MACs such as AES-XCBC-MAC.

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.

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!
