This patch fixes most of the sparse endianness warnings in stm32.
The patch itself doesn't change anything apart from markings,
but there is some questionable code in stm32_cryp_check_ctr_counter.
That function operates on the counters as if they're in CPU order,
however, they're then written out as big-endian. This looks like
a genuine bug. Therefore I've left that warning alone until
someone can confirm that this really does work as intended on
little-endian.

pm_runtime_get_sync() increments the runtime PM usage counter
even when it returns an error code. However, users of cc_pm_get(),

on the error handling path to keep the counter balanced.

This patch squashes all the sparse warnings in mediatek, some of
which appear to be genuine bugs. In particular, previously on
BE the keys and IVs all get 32-bit swabbed which can't be right
because they don't get swabbed on LE. I presume LE is the one
that actually works.
Another funky thing is that the GHASH key gets swabbed on LE.
This makes no sense but I'm presuming someone actually tested
this on LE so I'm preserving the swabbing. Someone needs to
test this though as it is entirely possible that GCM is the
only thing that worked on BE but not LE.

When the devices are removed or not existing, the corresponding algorithms
which are registered by 'hisi-zip' driver can't be used.
Move 'hisi_zip_register_to_crypto' from 'hisi_zip_init' to
'hisi_zip_probe'. The algorithms will be registered to crypto only when
there is device bind on the driver. And when the devices are removed,
the algorithms will be unregistered.
In the previous process, the function 'xxx_register_to_crypto' need a lock

A symmetric naming is only helpful if it implies symmetries in use.
Otherwise it's actively misleading.
In "kzalloc()", the z is meaningful and an important part of what the
caller wants.
In "kzfree()", the z is actively detrimental, because maybe in the
future we really _might_ want to use that "memfill(0xdeadbeef)" or
something. The "zero" part of the interface isn't even _relevant_.
The main reason that kzfree() exists is to clear sensitive information
that should not be leaked to other future users of the same memory
objects.
Rename kzfree() to kfree_sensitive() to follow the example of the recently
added kvfree_sensitive() and make the intention of the API more explicit.
In addition, memzero_explicit() is used to clear the memory to make sure
that it won't get optimized away by the compiler.
The renaming is done by using the command sequence:
git grep -w --name-only kzfree |\
xargs sed -i 's/kzfree/kfree_sensitive/'
followed by some editing of the kfree_sensitive() kerneldoc and adding
a kzfree backward compatibility macro in slab.h.

Nowadays output function has a 'synack_type' argument that tells us when
the syn/ack is emitted via syncookies.
The request already tells us when timestamps are supported, so check
both to detect special timestamp for tcp option encoding is needed.
We could remove cookie_ts altogether, but a followup patch would
otherwise need to adjust function signatures to pass 'want_cookie' to
mptcp core.
This way, the 'existing' bit can be used.

Drivers using legacy power management .suspen()/.resume() callbacks
have to manage PCI states and device's PM states themselves. They also
need to take care of standard configuration registers.
Switch to generic power management framework using a single
"struct dev_pm_ops" variable to take the unnecessary load from the driver.
This also avoids the need for the driver to directly call most of the PCI
helper functions and device power state control functions as through
the generic framework, PCI Core takes care of the necessary operations,
and drivers are required to do only device-specific jobs.

The UDP reuseport conflict was a little bit tricky.
The net-next code, via bpf-next, extracted the reuseport handling
into a helper so that the BPF sk lookup code could invoke it.
At the same time, the logic for reuseport handling of unconnected
sockets changed via commit efc6b6f6c3
which changed the logic to carry on the reuseport result into the
rest of the lookup loop if we do not return immediately.
This requires moving the reuseport_has_conns() logic into the callers.
While we are here, get rid of inline directives as they do not belong
in foo.c files.
The other changes were cases of more straightforward overlapping
modifications.

clang static analysis flags this error
qat_uclo.c:297:3: warning: Attempt to free released memory
[unix.Malloc]
kfree(*init_tab_base);
^~~~~~~~~~~~~~~~~~~~~
When input *init_tab_base is null, the function allocates memory for
the head of the list. When there is problem allocating other list
elements the list is unwound and freed. Then a check is made if the
list head was allocated and is also freed.
Keeping track of the what may need to be freed is the variable 'tail_old'.
The unwinding/freeing block is
while (tail_old) {
mem_init = tail_old->next;
kfree(tail_old);
tail_old = mem_init;
}
The problem is that the first element of tail_old is also what was
allocated for the list head
init_header = kzalloc(sizeof(*init_header), GFP_KERNEL);
...
*init_tab_base = init_header;
flag = 1;
}
tail_old = init_header;
So *init_tab_base/init_header are freed twice.
There is another problem.
When the input *init_tab_base is non null the tail_old is calculated by
traveling down the list to first non null entry.
tail_old = init_header;
while (tail_old->next)
tail_old = tail_old->next;
When the unwinding free happens, the last entry of the input list will
be freed.
So the freeing needs a general changed.
If locally allocated the first element of tail_old is freed, else it
is skipped. As a bit of cleanup, reset *init_tab_base if it came in
as null.

The AmLogic GXL crypto accelerator driver is built into the kernel if

defconfig enables all platforms by default, and so ARCH_MESON is usually

This means that the AmLogic driver causes the arm64 defconfig build to
pull in a huge chunk of the crypto stack as a builtin as well, which is
undesirable, so let's make the amlogic GXL driver default to 'm' instead.

Running the crypto manager self tests with
CONFIG_CRYPTO_MANAGER_EXTRA_TESTS may result in several types of errors
when using the ccp-crypto driver:
alg: skcipher: cbc-des3-ccp encryption failed on test vector 0; expected_error=0, actual_error=-5 ...
alg: skcipher: ctr-aes-ccp decryption overran dst buffer on test vector 0 ...
alg: ahash: sha224-ccp test failed (wrong result) on test vector ...
These errors are the result of improper processing of scatterlists mapped
for DMA.
Given a scatterlist in which entries are merged as part of mapping the
scatterlist for DMA, the DMA length of a merged entry will reflect the
combined length of the entries that were merged. The subsequent
scatterlist entry will contain DMA information for the scatterlist entry
after the last merged entry, but the non-DMA information will be that of
the first merged entry.
The ccp driver does not take this scatterlist merging into account. To
address this, add a second scatterlist pointer to track the current
position in the DMA mapped representation of the scatterlist. Both the DMA
representation and the original representation of the scatterlist must be
tracked as while most of the driver can use just the DMA representation,
scatterlist_map_and_copy() must use the original representation and
expects the scatterlist pointer to be accurate to the original
representation.
In order to properly walk the original scatterlist, the scatterlist must
be walked until the combined lengths of the entries seen is equal to the
DMA length of the current entry being processed in the DMA mapped
representation.

ahash_finup_no_ctx() returns -ENOMEM in most error cases,
and this is fine for almost all of them.
However, the return code provided by dpaa2_caam_enqueue()
(e.g. -EIO or -EBUSY) shouldn't be overridden by -ENOMEM.

The variable err is being initialized with a value that is never read
and it is being updated later with a new value. The initialization is
redundant and can be removed.

This patch fixes all the sparse warnings in the octeontx driver.
Some of these are just trivial type changes.
However, some of the changes are non-trivial on little-endian hosts.
Obviously the driver appears to be broken on either LE or BE as it
was doing different things. I've taken the BE behaviour as the
correct one.

As stress-ng running SEC engine on the Ubuntu OS,
we found that SEC only supports two threads each with one TFM
based on the default module parameter 'ctx_q_num'.
If running more threads, stress-ng will fail since it cannot
get more TFMs.
In order to fix this, we adjusted the default values
of the module parameters to support more TFMs.
