There is a regular need in the kernel to provide a way to declare having a
dynamically sized set of trailing elements in a structure. Kernel code should
always use “flexible array members”[1] for these cases. The older style of
one-element or zero-length arrays should no longer be used[2].

This patch fixes the compilation warnings displayed by sparse tool for
chcr driver.
V1->V2
Avoid type casting by using get_unaligned_be32() and
put_unaligned_be16/32() functions.
The key which comes from stack is an u8 byte stream so we store it in
an unsigned char array(ablkctx->key). The function get_aes_decrypt_key()
is a used to calculate the reverse round key for decryption, for this
operation the key has to be divided into 4 bytes, so to extract 4 bytes
from an u8 byte stream and store it in an u32 variable, get_aligned_be32()
is used. Similarly for copying back the key from u32 variable to the
original u8 key stream, put_aligned_be32() is used.

<linux/cryptohash.h> sounds very generic and important, like it's the
header to include if you're doing cryptographic hashing in the kernel.
But actually it only includes the library implementation of the SHA-1
compression function (not even the full SHA-1). This should basically
never be used anymore; SHA-1 is no longer considered secure, and there
are much better ways to do cryptographic hashing in the kernel.
Most files that include this header don't actually need it. So in
preparation for removing it, remove all these unneeded includes of it.

This solves the following issues observed during self test when
CONFIG_CRYPTO_MANAGER_EXTRA_TESTS is enabled.
1. Added fallback for cbc, ctr and rfc3686 if req->nbytes is zero
and for xts added a fallback case if req->nbytes is not multiple of 16.
2. In case of cbc-aes, solved wrong iv update. When
chcr_cipher_fallback() is called, used req->info pointer instead of
reqctx->iv.
3. In cbc-aes decryption there was a wrong result. This occurs when
chcr_cipher_fallback() is called from chcr_handle_cipher_resp().
In the fallback function iv(req->info) used is wrongly updated.
So use the initial iv for this case.
4)In case of ctr-aes encryption observed wrong result. In adjust_ctr_overflow()
there is condition which checks if ((bytes / AES_BLOCK_SIZE) > c),
where c is the number of blocks which can be processed without iv overflow,
but for the above bytes (req->nbytes < 32 , not a multiple of 16) this
condition fails and the 2nd block is corrupted as it requires the rollover iv.
So added a '=' condition in this to take care of this.
5)In rfc3686-ctr there was wrong result observed. This occurs when
chcr_cipher_fallback() is called from chcr_handle_cipher_resp().
Here also copying initial_iv in init_iv pointer for handling the fallback
case correctly.

This patch fixes two issues observed during self tests with

1. gcm(aes) hang issue , that happens during decryption.
2. rfc4106-gcm-aes-chcr encryption unexpectedly succeeded.
For gcm-aes decryption , authtag is not mapped due to
sg_nents_for_len(upto size: assoclen+ cryptlen - authsize).
So fix it by dma_mapping authtag.
Also replaced sg_nents() to sg_nents_for_len() in case of aead_dma_unmap().
For rfc4106-gcm-aes-chcr, used crypto_ipsec_check_assoclen() for checking
the validity of assoclen.

This reverts commit 27c6feb0fb.
For ipsec offload the chelsio's ethernet driver expects a single mtu
sized packet.
But when ipsec traffic is running using iperf, most of the packets in
that traffic are gso packets(large sized skbs) because GSO is enabled by
default in TCP, due to this commit 0a6b2a1dc2 ("tcp: switch to GSO
being always on"), so chcr_ipsec_offload_ok() receives a gso
skb(with gso_size non zero).
Due to the check in chcr_ipsec_offload_ok(), this function returns false
for most of the packet, then ipsec offload is skipped and the skb goes
out taking the coprocessor path which reduces the bandwidth for inline
ipsec.
If this check is removed then for most of the packets(large sized skbs)
the chcr_ipsec_offload_ok() returns true and then as GSO is on, the
segmentation of the packet happens in the kernel and then finally the
driver_xmit is called, which receives a segmented mtu sized packet which
is what the driver expects for ipsec offload. So this case becomes
unnecessary here, therefore removing it.

This issue occurs only when multiadapters are present. Hang

adapter which is not yet initialized as for this adapter cxgb_up
is not been called yet.
The last_dev pointer is used to determine u_ctx pointer and it
is initialized two times in chcr_uld_add in chcr_dev_add respectively.
The fix here is don't initialize the last_dev pointer during
chcr_uld_add. Only assign to value to it when the adapter's
initialization is completed i.e in chcr_dev_add.

Kernel TLS forms TLS header in kernel during encryption and removes
while decryption before giving packet back to user application. The
similar logic is introduced in chtls code as well.
v1->v2:
- tls_proccess_cmsg() uses tls_handle_open_record() which is not required
in TOE-TLS. Don't mix TOE with other TLS types.

This patch contains handling of first part or middle part of the record.
When we get a middle record, we will fetch few already sent bytes to
make packet start 16 byte aligned.
And if the packet has only the header part, we don't need to send it for
packet encryption, send that packet as a plaintext.
v1->v2:
- un-necessary updating left variable.
v3->v4:
- replaced kfree_skb with dev_kfree_skb_any.

TCP segment can chop a record in any order. Record can either be
complete or it can be partial (first part which contains header,
middle part which doesn't have header or TAG, and the end part
which contains TAG. This patch handles partial end part of a tx
record. In case of partial end part's, driver will send complete
record to HW, so that HW will calculate GHASH (TAG) of complete
packet.
Also added support to handle multiple records in a segment.
v1->v2:
- miner change in calling chcr_write_cpl_set_tcb_ulp.
- no need of checking return value of chcr_ktls_write_tcp_options.

A new macro is defined to enable ktls tx offload support on Chelsio
T6 adapter. And if this macro is enabled, cxgb4 will send mailbox to
enable or disable ktls settings on HW.
In chcr, enabled tx offload flag in netdev and registered tls_dev_add
and tls_dev_del.
v1->v2:
- mark tcb state to close in tls_dev_del.
- u_ctx is now picked from adapter structure.
- clear atid in case of failure.
- corrected ULP_CRYPTO_KTLS_INLINE value.

The current codebase makes use of the zero-length array language
extension to the C90 standard, but the preferred mechanism to declare
variable-length types such as these ones is a flexible array member[1][2],
introduced in C99:
struct foo {
int stuff;
struct boo array[];
};
By making use of the mechanism above, we will get a compiler warning
in case the flexible array does not occur last in the structure, which
will help us prevent some kind of undefined behavior bugs from being
inadvertently introduced[3] to the codebase from now on.
Also, notice that, dynamic memory allocations won't be affected by
this change:
"Flexible array members have incomplete type, and so the sizeof operator
may not be applied. As a quirk of the original implementation of
zero-length arrays, sizeof evaluates to zero."[1]
This issue was found with the help of Coccinelle.

kctx_len = (ntohl(KEY_CONTEXT_CTX_LEN_V(aeadctx->key_ctx_hdr)) << 4)
- sizeof(chcr_req->key_ctx);
can't possibly be endian-safe. Look: ->key_ctx_hdr is __be32. And
KEY_CONTEXT_CTX_LEN_V is "shift up by 24 bits". On little-endian hosts it
sees
b0 b1 b2 b3
in memory, inteprets that into b0 + (b1 << 8) + (b2 << 16) + (b3 << 24),
shifts up by 24, resulting in b0 << 24, does ntohl (byteswap on l-e),
gets b0 and shifts that up by 4. So we get b0 * 16 - sizeof(...).
Sounds reasonable, but on b-e we get
b3 + (b2 << 8) + (b1 << 16) + (b0 << 24), shift up by 24,
yielding b3 << 24, do ntohl (no-op on b-e) and then shift up by 4.
Resulting in b3 << 28 - sizeof(...), i.e. slightly under b3 * 256M.
Then we increase it some more and pass to alloc_skb() as size.
Somehow I doubt that we really want a quarter-gigabyte skb allocation
here...
Note that when you are building those values in
#define FILL_KEY_CTX_HDR(ck_size, mk_size, d_ck, opad, ctx_len) \
htonl(KEY_CONTEXT_VALID_V(1) | \
KEY_CONTEXT_CK_SIZE_V((ck_size)) | \
KEY_CONTEXT_MK_SIZE_V(mk_size) | \
KEY_CONTEXT_DUAL_CK_V((d_ck)) | \
KEY_CONTEXT_OPAD_PRESENT_V((opad)) | \
KEY_CONTEXT_SALT_PRESENT_V(1) | \
KEY_CONTEXT_CTX_LEN_V((ctx_len)))
ctx_len ends up in the first octet (i.e. b0 in the above), which
matches the current behaviour on l-e. If that's the intent, this
thing should've been
kctx_len = (KEY_CONTEXT_CTX_LEN_G(ntohl(aeadctx->key_ctx_hdr)) << 4)
- sizeof(chcr_req->key_ctx);
instead - fetch after ntohl() we get (b0 << 24) + (b1 << 16) + (b2 << 8) + b3,
shift it down by 24 (b0), resuling in b0 * 16 - sizeof(...) both on l-e and
on b-e.
PS: when sparse warns you about endianness problems, it might be worth checking
if there really is something wrong. And I don't mean "slap __force cast on it"...

chtls_uld_add allocates room for info->nports net_device structs
following the chtls_dev struct, presumably because it was originally
intended that the ports array would be stored there. This is suggested
by the assignment which was present in initial versions and removed by
c4e848586c ("crypto: chelsio - remove redundant assignment to
cdev->ports"):
cdev->ports = (struct net_device **)(cdev + 1);
This assignment was never used, being overwritten by lldi->ports
immediately afterwards, and I couldn't find any uses of the memory
allocated past the end of the struct.
