crytpo: caam - make use of iowrite64*_hi_lo in wr_reg64

In order to be able to unify 64 and 32 bit implementations of
wr_reg64, let's convert it to use helpers from
<linux/io-64-nonatomic-hi-lo.h> first. Here are the steps of the
transformation:

1. Inline wr_reg32 helpers:

if (!caam_imx && caam_little_end) {
if (caam_little_end) {
iowrite32(data >> 32, (u32 __iomem *)(reg) + 1);
iowrite32(data, (u32 __iomem *)(reg));
} else {
iowrite32be(data >> 32, (u32 __iomem *)(reg) + 1);
iowrite32be(data, (u32 __iomem *)(reg));
}
} else {
if (caam_little_end) {
iowrite32(data >> 32, (u32 __iomem *)(reg));
iowrite32(data, (u32 __iomem *)(reg) + 1);
} else {
iowrite32be(data >> 32, (u32 __iomem *)(reg));
iowrite32be(data, (u32 __iomem *)(reg) + 1);
}
}

2. Transfrom the conditionals such that the check for
'caam_little_end' is at the top level:

if (caam_little_end) {
if (!caam_imx) {
iowrite32(data >> 32, (u32 __iomem *)(reg) + 1);
iowrite32(data, (u32 __iomem *)(reg));
} else {
iowrite32(data >> 32, (u32 __iomem *)(reg));
iowrite32(data, (u32 __iomem *)(reg) + 1);
}
} else {
iowrite32be(data >> 32, (u32 __iomem *)(reg));
iowrite32be(data, (u32 __iomem *)(reg) + 1);
}

3. Invert the check for !caam_imx:

if (caam_little_end) {
if (caam_imx) {
iowrite32(data >> 32, (u32 __iomem *)(reg));
iowrite32(data, (u32 __iomem *)(reg) + 1);
} else {
iowrite32(data >> 32, (u32 __iomem *)(reg) + 1);
iowrite32(data, (u32 __iomem *)(reg));
}
} else {
iowrite32be(data >> 32, (u32 __iomem *)(reg));
iowrite32be(data, (u32 __iomem *)(reg) + 1);
}

4. Make use of iowrite64* helpers from <linux/io-64-nonatomic-hi-lo.h>

if (caam_little_end) {
if (caam_imx) {
iowrite32(data >> 32, (u32 __iomem *)(reg));
iowrite32(data, (u32 __iomem *)(reg) + 1);
} else {
iowrite64(data, reg);
}
} else {
iowrite64be(data, reg);
}

No functional change intended.

crypto: s390/xts-aes - invoke fallback for ciphertext stealing

For correctness and compliance with the XTS-AES specification, we are
adding support for ciphertext stealing to XTS implementations, even
though no use cases are known that will be enabled by this.

Since the s390 implementation already has a fallback skcipher standby
for other purposes, let's use it for this purpose as well. If ciphertext
stealing use cases ever become a bottleneck, we can always revisit this.

fs: cifs: move from the crypto cipher API to the new DES library interface

Some legacy code in the CIFS driver uses single DES to calculate
some password hash, and uses the crypto cipher API to do so. Given
that there is no point in invoking an accelerated cipher for doing
56-bit symmetric encryption on a single 8-byte block of input, the

random: Support freezable kthreads in add_hwgenerator_randomness()

The kthread calling this function is freezable after commit 03a3bb7ae631
("hwrng: core - Freeze khwrng thread during suspend") is applied.
Unfortunately, this function uses wait_event_interruptible() but doesn't
check for the kthread being woken up by the fake freezer signal. When a
user suspends the system, this kthread will wake up and if it fails the
entropy size check it will immediately go back to sleep and not go into
the freezer. Eventually, suspend will fail because the task never froze
and a warning message like this may appear:

 PM: suspend entry (deep)
 Filesystems sync: 0.000 seconds
 Freezing user space processes ... (elapsed 0.001 seconds) done.
 OOM killer disabled.

Check for a freezer signal here and skip adding any randomness if the
task wakes up because it was frozen. This should make the kthread freeze
properly and suspend work again.

crypto: arm64/aegis128 - implement plain NEON version

Provide a version of the core AES transform to the aegis128 SIMD
code that does not rely on the special AES instructions, but uses
plain NEON instructions instead. This allows the SIMD version of
the aegis128 driver to be used on arm64 systems that do not
implement those instructions (which are not mandatory in the

Since GCC makes a mess of this when using the tbl/tbx intrinsics
to perform the sbox substitution, preload the Sbox into v16..v31
in this case and use inline asm to emit the tbl/tbx instructions.
Clang does not support this approach, nor does it require it, since
it does a much better job at code generation, so there we use the
intrinsics as usual.

hwrng: core - Freeze khwrng thread during suspend

Let's make this kthread freezable so that we don't try to touch the
hwrng during suspend/resume. This ensures that we can't cause the hwrng
backing driver to get into a bad state because the device is guaranteed

padata: initialize pd->cpu with effective cpumask

Exercising CPU hotplug on a 5.2 kernel with recent padata fixes from
cryptodev-2.6.git in an 8-CPU kvm guest...

    # modprobe tcrypt alg="pcrypt(rfc4106(gcm(aes)))" type=3
    # echo 0 > /sys/devices/system/cpu/cpu1/online
    # echo c > /sys/kernel/pcrypt/pencrypt/parallel_cpumask
    # modprobe tcrypt mode=215

...caused the following crash:

    BUG: kernel NULL pointer dereference, address: 0000000000000000
    #PF: supervisor read access in kernel mode
    #PF: error_code(0x0000) - not-present page
    PGD 0 P4D 0
    Oops: 0000 [#1] SMP PTI
    CPU: 2 PID: 134 Comm: kworker/2:2 Not tainted 5.2.0-padata-base+ #7
    Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS 1.12.0-<snip>
    Workqueue: pencrypt padata_parallel_worker
    RIP: 0010:padata_reorder+0xcb/0x180
    ...
    Call Trace:
     padata_do_serial+0x57/0x60

     process_one_work+0x1b5/0x3f0
     worker_thread+0x4a/0x3c0
     ...

In padata_alloc_pd, pd->cpu is set using the user-supplied cpumask
instead of the effective cpumask, and in this case cpumask_first picked
an offline CPU.

The offline CPU's reorder->list.next is NULL in padata_reorder because
the list wasn't initialized in padata_init_pqueues, which only operates
on CPUs in the effective mask.

Fix by using the effective mask in padata_alloc_pd.

crypto: ccp - Include DMA declarations explicitly

ccp-dev.h uses dma_direction, which is defined in linux/dma-direction.h.
Include that explicitly instead of relying on it being included via
linux/pci.h, since ccp-dev.h requires nothing else from linux/pci.h.

Similarly, ccp-dmaengine.c uses dma_get_mask(), which is defined in
linux/dma-mapping.h, so include that explicitly since it requires nothing
else from linux/pci.h.

A future patch will remove the includes of linux/pci.h where it is not
needed.

Based on seqiv, IPsec ESP and rfc4543/rfc4106 the assoclen can be 16 or
20 bytes.

From esp4/esp6, assoclen is sizeof IP Header. This includes spi, seq_no
and extended seq_no, that is 8 or 12 bytes.
In seqiv, to asscolen is added the IV size (8 bytes).
Therefore, the assoclen, for rfc4543, should be restricted to 16 or 20
bytes, as for rfc4106.
