SP800-56A rev3 section 5.7.1.2 step 2 mandates that the validity of the
calculated shared secret is verified before the data is returned to the
caller. Thus, the export function and the validity check functions are
reversed. In addition, the sensitive variables of priv and rand_z are

of course means there are also no outstanding jobs.

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.

Introduce a new algorithm flag CRYPTO_ALG_ALLOCATES_MEMORY.  If this
flag is set, then the driver allocates memory in its request routine.
Such drivers are not suitable for disk encryption because GFP_ATOMIC
allocation can fail anytime (causing random I/O errors) and GFP_KERNEL
allocation can recurse into the block layer, causing a deadlock.

For now, this flag is only implemented for some algorithm types.  We
also assume some usage constraints for it to be meaningful, since there
are lots of edge cases the crypto API allows (e.g., misaligned or
fragmented scatterlists) that mean that nearly any crypto algorithm can
allocate memory in some case.  See the comment for details.

Also add this flag to CRYPTO_ALG_INHERITED_FLAGS so that when a template
is instantiated, this flag is set on the template instance if it is set
on any algorithm the instance uses.

CRYPTO_ALG_NEED_FALLBACK is handled inconsistently.  When it's requested
to be clear, some templates propagate that request to child algorithms,
while others don't.

It's apparently desired for NEED_FALLBACK to be propagated, to avoid
deadlocks where a module tries to load itself while it's being
initialized, and to avoid unnecessarily complex fallback chains where we
have e.g. cbc-aes-$driver falling back to cbc(aes-$driver) where
aes-$driver itself falls back to aes-generic, instead of cbc-aes-$driver
simply falling back to cbc(aes-generic).  There have been a number of
fixes to this effect:

commit 89027579 ("crypto: xts - Propagate NEED_FALLBACK bit")
commit d2c2a85c ("crypto: ctr - Propagate NEED_FALLBACK bit")
commit e6c2e65c ("crypto: cbc - Propagate NEED_FALLBACK bit")

But it seems that other templates can have the same problems too.

To avoid this whack-a-mole, just add NEED_FALLBACK to INHERITED_FLAGS so
that it's always inherited.

The flag CRYPTO_ALG_ASYNC is "inherited" in the sense that when a
template is instantiated, the template will have CRYPTO_ALG_ASYNC set if
any of the algorithms it uses has CRYPTO_ALG_ASYNC set.

We'd like to add a second flag (CRYPTO_ALG_ALLOCATES_MEMORY) that gets
"inherited" in the same way.  This is difficult because the handling of
CRYPTO_ALG_ASYNC is hardcoded everywhere.  Address this by:

  - Add CRYPTO_ALG_INHERITED_FLAGS, which contains the set of flags that
    have these inheritance semantics.

  - Add crypto_algt_inherited_mask(), for use by template ->create()
    methods.  It returns any of these flags that the user asked to be
    unset and thus must be passed in the 'mask' to crypto_grab_*().

  - Also modify crypto_check_attr_type() to handle computing the 'mask'
    so that most templates can just use this.

  - Make crypto_grab_*() propagate these flags to the template instance
    being created so that templates don't have to do this themselves.

Make crypto/simd.c propagate these flags too, since it "wraps" another
algorithm, similar to a template.
