0d95bdee02 crypto: sun4i-ss - initialize need_fallback
commit 4ec8977b921fd9d512701e009ce8082cb94b5c1c upstream.

The need_fallback is never initialized and seem to be always true at runtime.
So all hardware operations are always bypassed.

4fc52e091a crypto: sun4i-ss - checking sg length is not sufficient
commit 7bdcd851fa7eb66e8922aa7f6cba9e2f2427a7cf upstream.

The optimized cipher function need length multiple of 4 bytes.
But it get sometimes odd length.
This is due to SG data could be stored with an offset.

So the fix is to check also if the offset is aligned with 4 bytes.

adc2e1dba9 crypto: talitos - Work around SEC6 ERRATA (AES-CTR mode data size error)
[ Upstream commit 416b846757bcea20006a9197e67ba3a8b5b2a680 ]

Talitos Security Engine AESU considers any input
data size that is not a multiple of 16 bytes to be an error.
This is not a problem in general, except for Counter mode
that is a stream cipher and can have an input of any size.

Test Manager for ctr(aes) fails on 4th test vector which has
a length of 499 while all previous vectors which have a 16 bytes
multiple length succeed.

As suggested by Freescale, round up the input data length to the
nearest 16 bytes.

[ Upstream commit f7f2b43eaf6b4cfe54c75100709be31d5c4b52c8 ]

Renaming 'struct device_private' to 'struct bcm_device_private',
because it clashes with 'struct device_private' from
'drivers/base/base.h'.

While it's not a functional problem, it's causing two distinct
type hierarchies in BTF data. It also breaks build with options:
  CONFIG_DEBUG_INFO_BTF=y
  CONFIG_CRYPTO_DEV_BCM_SPU=y

as reported by Qais Yousef [1].

e056f69dea crypto: sun4i-ss - fix kmap usage
[ Upstream commit 9bc3dd24e7dccd50757db743a3635ad5b0497e6e ]

With the recent kmap change, some tests which were conditional on
CONFIG_DEBUG_HIGHMEM now are enabled by default.
This permit to detect a problem in sun4i-ss usage of kmap.

sun4i-ss uses two kmap via sg_miter (one for input, one for output), but
using two kmap at the same time is hard:
"the ordering has to be correct and with sg_miter that's probably hard to get
right." (quoting Tlgx)

So the easiest solution is to never have two sg_miter/kmap open at the same time.
After each use of sg_miter, I store the current index, for being able to
resume sg_miter to the right place.

[ Upstream commit 583513510a7acd2306787865bcd19ebb2f629d42 ]

When running the non-optimized cipher function, SS produce partial random

This is due to linearize buffers being reseted after each loop.

I move them in sun4i_ss_ctx.

9db1f14e70 cxgb4/chtls/cxgbit: Keeping the max ofld immediate data size same in cxgb4 and ulds
[ Upstream commit 2355a6773a2cb0d2dce13432dde78497f1d6617b ]

The Max imm data size in cxgb4 is not similar to the max imm data size
in the chtls. This caused an mismatch in output of is_ofld_imm() of
cxgb4 and chtls. So fixed this by keeping the max wreq size of imm data
same in both chtls and cxgb4 as MAX_IMM_OFLD_TX_DATA_WR_LEN.

As cxgb4's max imm. data value for ofld packets is changed to
MAX_IMM_OFLD_TX_DATA_WR_LEN. Using the same in cxgbit also.

3a0d5b5358 chelsio/chtls: fix tls record info to user
[ Upstream commit 4f3391ce8f5a69e7e6d66d0a3fc654eb6dbdc919 ]

chtls_pt_recvmsg() receives a skb with tls header and subsequent
skb with data, need to finalize the data copy whenever next skb
with tls header is available. but here current tls header is
overwritten by next available tls header, ends up corrupting
user buffer data. fixing it by finalizing current record whenever
next skb contains tls header.

28bd8f392f crypto: ccp - Fix use of merged scatterlists
commit 8a302808c60d441d9884cb00ea7f2b534f2e3ca5 upstream.

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.

clang static analysis flags this error

qat_uclo.c:297:3: warning: Attempt to free released memory

                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.

d9add5d7d9 crypto: hisilicon - don't sleep of CRYPTO_TFM_REQ_MAY_SLEEP was not specified
commit 5ead051780404b5cb22147170acadd1994dc3236 upstream.

There is this call chain:
sec_alg_skcipher_encrypt -> sec_alg_skcipher_crypto ->
sec_alg_alloc_and_calc_split_sizes -> kcalloc
where we call sleeping allocator function even if CRYPTO_TFM_REQ_MAY_SLEEP
was not specified.
