The RFC4106 key derivation code instantiates an AES cipher transform
to encrypt only a single block before it is freed again. Switch to
the new AES library which is more suitable for such use cases.

The AES-NI code contains fallbacks for invocations that occur from a
context where the SIMD unit is unavailable, which really only occurs
when running in softirq context that was entered from a hard IRQ that
was taken while running kernel code that was already using the FPU.
That means performance is not really a consideration, and we can just
use the new library code for this use case, which has a smaller
footprint and is believed to be time invariant. This will allow us to
drop the non-SIMD asm routines in a subsequent patch.

gcmaes_crypt_by_sg() dereferences the NULL pointer returned by
scatterwalk_ffwd() when encrypting an empty plaintext and the source
scatterlist ends immediately after the associated data.
Fix it by only fast-forwarding to the src/dst data scatterlists if the
data length is nonzero.
This bug is reproduced by the "rfc4543(gcm(aes))" test vectors when run
with the new AEAD test manager.

Add the appropriate scatter/gather stubs to the avx asm.
In the C code, we can now always use crypt_by_sg, since both
sse and asm code now support scatter/gather.
Introduce a new struct, aesni_gcm_tfm, that is initialized on
startup to point to either the SSE, AVX, or AVX2 versions of the
four necessary encryption/decryption routines.
GENX_OPTSIZE is still checked at the start of crypt_by_sg. The
total size of the data is checked, since the additional overhead
is in the init function, calculating additional HashKeys.

Add support for 192/256-bit keys using the avx gcm/aes routines.
The sse routines were previously updated in e31ac32d3b (Add support
for 192 & 256 bit keys to AESNI RFC4106).
Instead of adding an additional loop in the hotpath as in e31ac32d3b,
this diff instead generates separate versions of the code using macros,
and the entry routines choose which version once. This results
in a 5% performance improvement vs. adding a loop to the hot path.
This is the same strategy chosen by the intel isa-l_crypto library.
The key size checks are removed from the c code where appropriate.
Note that this diff depends on using gcm_context_data - 256 bit keys
require 16 HashKeys + 15 expanded keys, which is larger than
struct crypto_aes_ctx, so they are stored in struct gcm_context_data.

necessary for avx.

For historical reasons, the AES-NI based implementation of the PCBC
chaining mode uses a special FPU chaining mode wrapper template to
amortize the FPU start/stop overhead over multiple blocks.
When this FPU wrapper was introduced, it supported widely used
chaining modes such as XTS and CTR (as well as LRW), but currently,
PCBC is the only remaining user.
Since there are no known users of pcbc(aes) in the kernel, let's remove
this special driver, and rely on the generic pcbc driver to encapsulate
the AES-NI core cipher.

Authenticated encryption may be used by dm-crypt. If the encryption or

Add gcmaes_crypt_by_sg routine, that will do scatter/gather
by sg. Either src or dst may contain multiple buffers, so
iterate over both at the same time if they are different.
If the input is the same as the output, iterate only over one.
Currently both the AAD and TAG must be linear, so copy them out
with scatterlist_map_and_copy. If first buffer contains the
entire AAD, we can optimize and not copy. Since the AAD
can be any size, if copied it must be on the heap. TAG can
be on the stack since it is always < 16 bytes.
Only the SSE routines are updated so far, so leave the previous
gcmaes_en/decrypt routines, and branch to the sg ones if the
keysize is inappropriate for avx, or we are SSE only.

GCM can be invoked with a zero destination buffer. This is possible if
the AAD and the ciphertext have zero lengths and only the tag exists in
the source buffer (i.e. a source buffer cannot be zero). In this case,
the GCM cipher only performs the authentication and no decryption
operation.
When the destination buffer has zero length, it is possible that no page
is mapped to the SG pointing to the destination. In this case,
sg_page(req->dst) is an invalid access. Therefore, page accesses should
only be allowed if the req->dst->length is non-zero which is the
indicator that a page must exist.
This fixes a crash that can be triggered by user space via AF_ALG.

There are quite a number of occurrences in the kernel of the pattern
if (dst != src)
memcpy(dst, src, walk.total % AES_BLOCK_SIZE);
crypto_xor(dst, final, walk.total % AES_BLOCK_SIZE);
or
crypto_xor(keystream, src, nbytes);
memcpy(dst, keystream, nbytes);
where crypto_xor() is preceded or followed by a memcpy() invocation
that is only there because crypto_xor() uses its output parameter as
one of the inputs. To avoid having to add new instances of this pattern
in the arm64 code, which will be refactored to implement non-SIMD
fallbacks, add an alternative implementation called crypto_xor_cpy(),
taking separate input and output arguments. This removes the need for
the separate memcpy().

The rfc4106 encrypy/decrypt helper functions cause an annoying
false-positive warning in allmodconfig if we turn on
-Wmaybe-uninitialized warnings again:
arch/x86/crypto/aesni-intel_glue.c: In function ‘helper_rfc4106_decrypt’:
include/linux/scatterlist.h:67:31: warning: ‘dst_sg_walk.sg’ may be used uninitialized in this function [-Wmaybe-uninitialized]
The problem seems to be that the compiler doesn't track the state of the
'one_entry_in_sg' variable across the kernel_fpu_begin/kernel_fpu_end
section.
This takes the easy way out by adding a bogus initialization, which
should be harmless enough to get the patch into v4.9 so we can turn on
this warning again by default without producing useless output. A

Currently aesni uses an async ctr(aes) to derive the rfc4106
subkey, which was presumably copied over from the generic rfc4106
code. Over there it's done that way because we already have a
ctr(aes) spawn. But it is simply overkill for aesni since we
have to go get a ctr(aes) from scratch anyway.
This patch simplifies the subkey derivation by using a straight

In addition, this service function received a check to ensure that the

The low-level interface remains as is for now because we can't
touch it until cryptd itself is upgraded.
In the conversion I've also removed the duplicate copy of the
context in the top-level algorithm. Now all processing is carried
out in the low-level __driver-gcm-aes-aesni algorithm.

We already have fpu/types.h, move i387.h to fpu/api.h.
The file name has become a misnomer anyway: it offers generic FPU APIs,
but is not limited to i387 functionality.

This patch uses the crypto_aead_set_reqsize helper to avoid directly
touching the internals of aead.

Pull crypto update from Herbert Xu:
"Here is the crypto update for 4.1:
New interfaces:
- user-space interface for AEAD
- user-space interface for RNG (i.e., pseudo RNG)
New hashes:
- ARMv8 SHA1/256
- ARMv8 AES
- ARMv8 GHASH
- ARM assembler and NEON SHA256
- MIPS OCTEON SHA1/256/512
- MIPS img-hash SHA1/256 and MD5
- Power 8 VMX AES/CBC/CTR/GHASH
- PPC assembler AES, SHA1/256 and MD5
- Broadcom IPROC RNG driver
Cleanups/fixes:
- prevent internal helper algos from being exposed to user-space
- merge common code from assembly/C SHA implementations
- misc fixes"

Flag all AES-NI helper ciphers as internal ciphers to prevent them from
being called by normal users.
