Eric Biggers 674f368a95 crypto: remove CRYPTO_TFM_RES_BAD_KEY_LEN
The CRYPTO_TFM_RES_BAD_KEY_LEN flag was apparently meant as a way to
make the ->setkey() functions provide more information about errors.

However, no one actually checks for this flag, which makes it pointless.

Also, many algorithms fail to set this flag when given a bad length key.
Reviewing just the generic implementations, this is the case for
aes-fixed-time, cbcmac, echainiv, nhpoly1305, pcrypt, rfc3686, rfc4309,
rfc7539, rfc7539esp, salsa20, seqiv, and xcbc.  But there are probably
many more in arch/*/crypto/ and drivers/crypto/.

Some algorithms can even set this flag when the key is the correct
length.  For example, authenc and authencesn set it when the key payload
is malformed in any way (not just a bad length), the atmel-sha and ccree
drivers can set it if a memory allocation fails, and the chelsio driver
sets it for bad auth tag lengths, not just bad key lengths.

So even if someone actually wanted to start checking this flag (which
seems unlikely, since it's been unused for a long time), there would be
a lot of work needed to get it working correctly.  But it would probably
be much better to go back to the drawing board and just define different
return values, like -EINVAL if the key is invalid for the algorithm vs.
-EKEYREJECTED if the key was rejected by a policy like "no weak keys".
That would be much simpler, less error-prone, and easier to test.

So just remove this flag.

Ard Biesheuvel b5e5c373ea crypto: ux500 - switch to skcipher API
Commit 7a7ffe65c8 ("crypto: skcipher - Add top-level skcipher interface")
dated 20 august 2015 introduced the new skcipher API which is supposed to
replace both blkcipher and ablkcipher. While all consumers of the API have
been converted long ago, some producers of the ablkcipher remain, forcing
us to keep the ablkcipher support routines alive, along with the matching
code to expose [a]blkciphers via the skcipher API.

So switch this driver to the skcipher API, allowing us to finally drop the
ablkcipher code in the near future.

Ard Biesheuvel 04007b0e6c crypto: des - split off DES library from generic DES cipher driver
Another one for the cipher museum: split off DES core processing into
a separate module so other drivers (mostly for crypto accelerators)
can reuse the code without pulling in the generic DES cipher itself.
This will also permit the cipher interface to be made private to the
crypto API itself once we move the only user in the kernel (CIFS) to
this library interface.

Eric Biggers 231baecdef crypto: clarify name of WEAK_KEY request flag
CRYPTO_TFM_REQ_WEAK_KEY confuses newcomers to the crypto API because it
sounds like it is requesting a weak key.  Actually, it is requesting
that weak keys be forbidden (for algorithms that have the notion of
"weak keys"; currently only DES and XTS do).

Also it is only one letter away from CRYPTO_TFM_RES_WEAK_KEY, with which
it can be easily confused.  (This in fact happened in the UX500 driver,
though just in some debugging messages.)

Therefore, make the intent clear by renaming it to
CRYPTO_TFM_REQ_FORBID_WEAK_KEYS.

Kamil Konieczny 3c9418f23e crypto: ux500/hash - Add empty export and import
Crypto framework requires export/import in async hash. If driver do not
implement them, wrapper functions in framework will be used, and it will
cause error during ahash alg registration (unless one disables crypto
internal tests). To make change in framework and expose this requirement,
I will remove wrappers from crypto/ahash.c , but this can broke code which
depends on them. Add empty hash export and import, with the same behaviour
as in framework and expose this directly in driver. This can also prevent
OOPS when config option in Cryptographic API 'Disable run-time self tests'
will be enabled.

Arnd Bergmann 9ac1c3200c crypto: ux500 - do not build with -O0
The ARM allmodconfig build currently warngs because of the
ux500 crypto driver not working well with the jump label
implementation that we started using for dynamic debug, which
breaks building with 'gcc -O0':

Turning off compiler optimizations has never really been supported
here, and it's only used when debugging the driver. I have not found
a good reason for doing this here, other than a misguided attempt
to produce more readable assembly output. Also, the driver is only
used in obsolete hardware that almost certainly nobody will spend
time debugging any more.

This just removes the -O0 flag from the compiler options.

2. Do not select ALGAPI unless you use a legacy type like
CRYPTO_ALG_TYPE_CIPHER.
3. Select the algorithm type that you are implementing, e.g., AEAD.
4. Do not select generic C code such as CBC/ECB unless you use them

The interrupt handler in the ux500 crypto driver has an obviously
incorrect way to access the data buffer, which for a while has

 static inline __attribute_const__ __u32 __fswab32(__u32 val)

There are at least two, possibly three problems here:
a) when writing into the FIFO, we copy the pointer rather than the
   actual data we want to give to the hardware
b) the data pointer is an array of 8-bit values, while the FIFO
   is 32-bit wide, so both the read and write access fail to do
   a proper type conversion
c) This seems incorrect for big-endian kernels, on which we need to
   byte-swap any register access, but not normally FIFO accesses,
   at least the DMA case doesn't do it either.

This converts the bogus loop to use the same readsl/writesl pair
that we use for the two other modes (DMA and polling). This is
more efficient and consistent, and probably correct for endianess.

The bug has existed since the driver was first merged, and was
probably never detected because nobody tried to use interrupt mode.
It might make sense to backport this fix to stable kernels, depending
on how the crypto maintainers feel about that.
