[ Upstream commit 228d284aac61283cde508a925d666f854b57af63 ]
In the init loop, if an error occurs in function 'dma_alloc_coherent',
then goto the err_cleanup section, after run i--,
in the array ring, the struct mtk_ring with index i will not be released,
causing memory leaks

[ Upstream commit 3faf757bad75f3fc1b2736f0431e295a073a7423 ]
Running export/import for hashes in peculiar order (mostly done by
openssl) can mess up the internal book keeping of the OMAP SHA core.
Fix by forcibly writing the correct DIGCNT back to hardware. This issue
was noticed while transitioning to openssl 1.1 support.

commit 45cb6653b0c355fc1445a8069ba78a4ce8720511 upstream.
Return -EINVAL for authenc(hmac(sha1),cbc(aes)),
authenc(hmac(sha256),cbc(aes)) and authenc(hmac(sha512),cbc(aes))
if the cipher length is not multiple of the AES block.
This is to prevent an undefined device behaviour.

commit 10a2f0b311094ffd45463a529a410a51ca025f27 upstream.
The setkey function for GCM/CCM algorithms didn't verify the key
length before copying the key and subtracting the salt length.
This patch delays the copying of the key til after the verification
has been done. It also adds checks on the key length to ensure
that it's at least as long as the salt.

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.

commit c06c76602e03bde24ee69a2022a829127e504202 upstream.
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.

[ Upstream commit eebac678556d6927f09a992872f4464cf3aecc76 ]
DMADEVICES is the top-level option for the slave DMA
subsystem, and should not be selected by device drivers,
as this can cause circular dependencies such as:
drivers/net/ethernet/freescale/Kconfig:6:error: recursive dependency detected!
drivers/net/ethernet/freescale/Kconfig:6: symbol NET_VENDOR_FREESCALE depends on PPC_BESTCOMM
drivers/dma/bestcomm/Kconfig:6: symbol PPC_BESTCOMM depends on DMADEVICES
drivers/dma/Kconfig:6: symbol DMADEVICES is selected by CRYPTO_DEV_SP_CCP
drivers/crypto/ccp/Kconfig:10: symbol CRYPTO_DEV_SP_CCP depends on CRYPTO
crypto/Kconfig:16: symbol CRYPTO is selected by LIBCRC32C
lib/Kconfig:222: symbol LIBCRC32C is selected by LIQUIDIO
drivers/net/ethernet/cavium/Kconfig:65: symbol LIQUIDIO depends on PTP_1588_CLOCK
drivers/ptp/Kconfig:8: symbol PTP_1588_CLOCK is implied by FEC
drivers/net/ethernet/freescale/Kconfig:23: symbol FEC depends on NET_VENDOR_FREESCALE
The LIQUIDIO driver causing this problem is addressed in a
separate patch, but this change is needed to prevent it from
happening again.
Using "depends on DMADEVICES" is what we do for all other
implementations of slave DMA controllers as well.

[ Upstream commit 8c855f0720ff006d75d0a2512c7f6c4f60ff60ee ]
The system'll crash when the users insmod crypto/tcrypto.ko with mode=155
( testing "authenc(hmac(sha1),cbc(aes))" ). It's caused by reuse the memory
of request structure.
In crypto_authenc_init_tfm(), the reqsize is set to:
[PART 1] sizeof(authenc_request_ctx) +
[PART 2] ictx->reqoff +
[PART 3] MAX(ahash part, skcipher part)
and the 'PART 3' is used by both ahash and skcipher in turn.
When the virtio_crypto driver finish skcipher req, it'll call ->complete
callback(in crypto_finalize_skcipher_request) and then free its
resources whose pointers are recorded in 'skcipher parts'.
However, the ->complete is 'crypto_authenc_encrypt_done' in this case,
it will use the 'ahash part' of the request and change its content,
so virtio_crypto driver will get the wrong pointer after ->complete
finish and mistakenly free some other's memory. So the system will crash
when these memory will be used again.
The resources which need to be cleaned up are not used any more. But the
pointers of these resources may be changed in the function
"crypto_finalize_skcipher_request". Thus release specific resources before
calling this function.

first field of 'struct crypto_aead'. Consequently, the calls to
crypto_tfm_set_flags() are modifying some other field in the struct.
Also, the driver is setting CRYPTO_TFM_RES_BAD_KEY_LEN in
->setauthsize(), not just in ->setkey(). This is incorrect since this
flag is for bad key lengths, not for bad authentication tag lengths.
Fix these bugs by removing the broken crypto_tfm_set_flags() calls from
->setauthsize() and by fixing them in ->setkey().

[ Upstream commit 72c8117adfced37df101c8c0b3f363e0906f83f0 ]
Each of the operations in ccp_run_cmd() needs several hundred
bytes of kernel stack. Depending on the inlining, these may
need separate stack slots that add up to more than the warning
limit, as shown in this clang based build:
drivers/crypto/ccp/ccp-ops.c:871:12: error: stack frame size of 1164 bytes in function 'ccp_run_aes_cmd' [-Werror,-Wframe-larger-than=]
static int ccp_run_aes_cmd(struct ccp_cmd_queue *cmd_q, struct ccp_cmd *cmd)
The problem may also happen when there is no warning, e.g. in the
ccp_run_cmd()->ccp_run_aes_cmd()->ccp_run_aes_gcm_cmd() call chain with
over 2000 bytes.
Mark each individual function as 'noinline_for_stack' to prevent
this from happening, and move the calls to the two special cases for aes
into the top-level function. This will keep the actual combined stack
usage to the mimimum: 828 bytes for ccp_run_aes_gcm_cmd() and
at most 524 bytes for each of the other cases.

[ Upstream commit 4ee812f6143d78d8ba1399671d78c8d78bf2817c ]
In the vmx crypto Makefile we assign to a variable called TARGET and
pass that to the aesp8-ppc.pl and ghashp8-ppc.pl scripts.
The variable is meant to describe what flavour of powerpc we're
building for, eg. either 32 or 64-bit, and big or little endian.
Unfortunately TARGET is a fairly common name for a make variable, and
if it happens that TARGET is specified as a command line parameter to
make, the value specified on the command line will override our value.
In particular this can happen if the kernel Makefile is driven by an
external Makefile that uses TARGET for something.
This leads to weird build failures, eg:
nonsense at /build/linux/drivers/crypto/vmx/ghashp8-ppc.pl line 45.
/linux/drivers/crypto/vmx/Makefile:20: recipe for target 'drivers/crypto/vmx/ghashp8-ppc.S' failed
Which shows that we passed an empty value for $(TARGET) to the perl
script, confirmed with make V=1:
perl /linux/drivers/crypto/vmx/ghashp8-ppc.pl > drivers/crypto/vmx/ghashp8-ppc.S
We can avoid this confusion by using override, to tell make that we
don't want anything to override our variable, even a value specified
on the command line. We can also use a less common name, given the
script calls it "flavour", let's use that.

ccp_tx_submit is passed a dma_async_tx_descriptor which is contained in
a ccp_dma_desc and adds it to a ccp channel's pending list:
list_del(&desc->entry);
list_add_tail(&desc->entry, &chan->pending);
The problem is that desc->entry may be uninitialized in the
async_trigger_callback path where the descriptor was gotten
from ccp_prep_dma_interrupt which got it from ccp_alloc_dma_desc
which doesn't initialize the desc->entry list head. So, just
initialize the list head to avoid the problem.

If ofifo -> external memory transfer happens first, DECO will hang

Make sure IV transfer happens first by waiting for all CAAM internal
transfers to end before starting payload transfer.

commit c552ffb5c93d9d65aaf34f5f001c4e7e8484ced1 upstream.
