commit 9e27c99104707f083dccd3b4d79762859b5a0614 upstream.
There is this call chain:
cvm_encrypt -> cvm_enc_dec -> cptvf_do_request -> process_request -> kzalloc
where we call sleeping allocator function even if CRYPTO_TFM_REQ_MAY_SLEEP
was not specified.

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/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.

tasklet_kill
commit 7f8c36fe9be46862c4f3c5302f769378028a34fa upstream.
Since tasklet is needed to be initialized before registering IRQ
handler, adjust the position of tasklet_init to fix the wrong order.
Besides, to fix the missed tasklet_kill, this patch adds a helper
function and uses devm_add_action to kill the tasklet automatically.

commit 11548f5a5747813ff84bed6f2ea01100053b0d8d upstream.
AMD Seattle incorporates a non-PCI version of the v3 CCP crypto
accelerator, and this version was left behind when the maximum
RSA modulus size was parameterized in order to support v5 hardware
which supports larger moduli than v3 hardware does. Due to this
oversight, RSA acceleration no longer works at all on these systems.
Fix this by setting the .rsamax property to the appropriate value
for v3 platform hardware.

commit 4549f7e5aa27ffc2cba63b5db8842a3b486f5688 upstream.
The geode AES driver is heavily broken because it stores per-request
state in the transform context. So it will crash or produce the wrong
result if used by any of the many places in the kernel that issue
concurrent requests for the same transform object.
This driver is also implemented using the deprecated blkcipher API,
which makes it difficult to fix, and puts it among the drivers
preventing that API from being removed.
Convert this driver to use the skcipher API, and change it to not store
per-request state in the transform context.

commit bd56cea012fc2d6381e8cd3209510ce09f9de8c9 upstream.
The chelsio crypto driver is casting 'struct crypto_aead' directly to
'struct crypto_tfm', which is incorrect because the crypto_tfm isn't the
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().

commit 504582e8e40b90b8f8c58783e2d1e4f6a2b71a3a upstream.
Commit 79c65d179a40e145 ("crypto: cbc - Convert to skcipher") updated
the generic CBC template wrapper from a blkcipher to a skcipher algo,
to get away from the deprecated blkcipher interface. However, as a side
effect, drivers that instantiate CBC transforms using the blkcipher as
a fallback no longer work, since skciphers can wrap blkciphers but not
the other way around. This broke the geode-aes driver.
So let's fix it by moving to the sync skcipher interface when allocating
the fallback. At the same time, align with the generic API for ECB and
CBC by rejecting inputs that are not a multiple of the AES block size.

[ 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.
