This patch adds a requirement to the generic 3DES implementation
such that 2-key 3DES (K1 == K3) is no longer allowed in FIPS mode.
We will also provide helpers that may be used by drivers that
implement 3DES to make the same check.

In the VMX implementations of AES and AES modes, return -EINVAL when an
invalid key length is provided, rather than some unusual error code
determined via a series of additions. This makes the behavior match the
other AES implementations in the kernel's crypto API.

If the user-provided IV needs to be aligned to the algorithm's
alignmask, then skcipher_walk_virt() copies the IV into a new aligned
buffer walk.iv. But skcipher_walk_virt() can fail afterwards, and then
if the caller unconditionally accesses walk.iv, it's a use-after-free.
xts-aes-neonbs doesn't set an alignmask, so currently it isn't affected
by this despite unconditionally accessing walk.iv. However this is more
subtle than desired, and unconditionally accessing walk.iv has caused a
real problem in other algorithms. Thus, update xts-aes-neonbs to start
checking the return value of skcipher_walk_virt().

Add a module parameter cryptomgr.panic_on_fail which causes the kernel
to panic if any crypto self-tests fail.
Use cases:
- More easily detect crypto self-test failures by boot testing,
e.g. on KernelCI.
- Get a bug report if syzkaller manages to use the template system to
instantiate an algorithm that fails its self-tests.
The command-line option "fips=1" already does this, but it also makes
other changes not wanted for general testing, such as disabling
"unapproved" algorithms. panic_on_fail just does what it says.

My patches to make testmgr fuzz algorithms against their generic
implementation detected that the arm64 implementations of "cbcmac(aes)"
handle empty messages differently from the cbcmac template. Namely, the
arm64 implementations return the encrypted initial value, but the cbcmac
template returns the initial value directly.
This isn't actually a meaningful case because any user of cbcmac needs
to prepend the message length, as CCM does; otherwise it's insecure.
However, we should keep the behavior consistent; at the very least this
makes testing easier.
Do it the easy way, which is to change the arm64 implementations to have
the same behavior as the cbcmac template.
For what it's worth, ghash does things essentially the same way: it
returns its initial value when given an empty message, even though in
practice ghash is never passed an empty message.

My patches to make testmgr fuzz algorithms against their generic
implementation detected that the arm64 implementations of
"cts(cbc(aes))" handle empty messages differently from the cts template.
Namely, the arm64 implementations forbids (with -EINVAL) all messages
shorter than the block size, including the empty message; but the cts
template permits empty messages as a special case.
No user should be CTS-encrypting/decrypting empty messages, but we need
to keep the behavior consistent. Unfortunately, as noted in the source
of OpenSSL's CTS implementation [1], there's no common specification for
CTS. This makes it somewhat debatable what the behavior should be.
However, all CTS specifications seem to agree that messages shorter than
the block size are not allowed, and OpenSSL follows this in both CTS
conventions it implements. It would also simplify the user-visible
semantics to have empty messages no longer be a special case.
Therefore, make the cts template return -EINVAL on *all* messages
shorter than the block size, including the empty message.

If the rfc7539 template is instantiated with specific implementations,
e.g. "rfc7539(chacha20-generic,poly1305-generic)" rather than
"rfc7539(chacha20,poly1305)", then the implementation names end up
included in the instance's cra_name. This is incorrect because it then
prevents all users from allocating "rfc7539(chacha20,poly1305)", if the
highest priority implementations of chacha20 and poly1305 were selected.
Also, the self-tests aren't run on an instance allocated in this way.
Fix it by setting the instance's cra_name from the underlying
algorithms' actual cra_names, rather than from the requested names.
This matches what other templates do.

skcipher_walk_done() assumes it's a bug if, after the "slow" path is
executed where the next chunk of data is processed via a bounce buffer,
the algorithm says it didn't process all bytes. Thus it WARNs on this.
However, this can happen legitimately when the message needs to be
evenly divisible into "blocks" but isn't, and the algorithm has a
'walksize' greater than the block size. For example, ecb-aes-neonbs
sets 'walksize' to 128 bytes and only supports messages evenly divisible
into 16-byte blocks. If, say, 17 message bytes remain but they straddle
scatterlist elements, the skcipher_walk code will take the "slow" path
and pass the algorithm all 17 bytes in the bounce buffer. But the
algorithm will only be able to process 16 bytes, triggering the WARN.
Fix this by just removing the WARN_ON(). Returning -EINVAL, as the code
already does, is the right behavior.
This bug was detected by my patches that improve testmgr to fuzz
algorithms against their generic implementation.

Two per-CPU variables are allocated as pointer to per-CPU memory which
then are used as scratch buffers.
We could be smart about this and use instead a per-CPU struct which
contains the pointers already and then we need to allocate just the
scratch buffers.
Add a lock to the struct. By doing so we can avoid the get_cpu()
statement and gain lockdep coverage (if enabled) to ensure that the lock
is always acquired in the right context. On non-preemptible kernels the
lock vanishes.
It is okay to use raw_cpu_ptr() in order to get a pointer to the struct
since it is protected by the spinlock.
The diffstat of this is negative and according to size scompress.o:
text data bss dec hex filename
1847 160 24 2031 7ef dbg_before.o
1754 232 4 1990 7c6 dbg_after.o
1799 64 24 1887 75f no_dbg-before.o
1703 88 4 1795 703 no_dbg-after.o
The overall size increase difference is also negative. The increase in
the data section is only four bytes without lockdep.

Some i.MX6 devices (imx6D, imx6Q, imx6DL, imx6S, imx6DP and imx6DQ) have
an issue wherein AXI bus transactions may not occur in the correct order.
This isn't a problem running single descriptors, but can be if running
multiple concurrent descriptors. Reworking the CAAM driver to throttle
to single requests is impractical, so this patch limits the AXI pipeline
to a depth of one (from a default of 4) to preclude this situation from
occurring.
This patch applies to known affected platforms.

The register write is done using wr_reg32() which internally uses
