8ac05d760d UPSTREAM: crypto: arm/blake2s - fix for big endian
The new ARM BLAKE2s code doesn't work correctly (fails the self-tests)
in big endian kernel builds because it doesn't swap the endianness of
the message words when loading them.  Fix this.

2d99053675 BACKPORT: crypto: arm/blake2b - add NEON-accelerated BLAKE2b
Add a NEON-accelerated implementation of BLAKE2b.

On Cortex-A7 (which these days is the most common ARM processor that
doesn't have the ARMv8 Crypto Extensions), this is over twice as fast as
SHA-256, and slightly faster than SHA-1.  It is also almost three times
as fast as the generic implementation of BLAKE2b:

	Algorithm            Cycles per byte (on 4096-byte messages)
	===================  =======================================
	blake2b-256-neon     14.0
	sha1-neon            16.3
	blake2s-256-arm      18.8
	sha1-asm             20.8
	blake2s-256-generic  26.0
	sha256-neon	     28.9
	sha256-asm	     32.0
	blake2b-256-generic  38.9

This implementation isn't directly based on any other implementation,
but it borrows some ideas from previous NEON code I've written as well
as from chacha-neon-core.S.  At least on Cortex-A7, it is faster than
the other NEON implementations of BLAKE2b I'm aware of (the
implementation in the BLAKE2 official repository using intrinsics, and
Andrew Moon's implementation which can be found in SUPERCOP).  It does
only one block at a time, so it performs well on short messages too.

NEON-accelerated BLAKE2b is useful because there is interest in using
BLAKE2b-256 for dm-verity on low-end Android devices (specifically,
devices that lack the ARMv8 Crypto Extensions) to replace SHA-1.  On
these devices, the performance cost of upgrading to SHA-256 may be
unacceptable, whereas BLAKE2b-256 would actually improve performance.

Although BLAKE2b is intended for 64-bit platforms (unlike BLAKE2s which
is intended for 32-bit platforms), on 32-bit ARM processors with NEON,
BLAKE2b is actually faster than BLAKE2s.  This is because NEON supports
64-bit operations, and because BLAKE2s's block size is too small for
NEON to be helpful for it.  The best I've been able to do with BLAKE2s
on Cortex-A7 is 18.8 cpb with an optimized scalar implementation.

(I didn't try BLAKE2sp and BLAKE3, which in theory would be faster, but
they're more complex as they require running multiple hashes at once.
Note that BLAKE2b already uses all the NEON bandwidth on the Cortex-A7,
so I expect that any speedup from BLAKE2sp or BLAKE3 would come only
from the smaller number of rounds, not from the extra parallelism.)

For now this BLAKE2b implementation is only wired up to the shash API,
since there is no library API for BLAKE2b yet.  However, I've tried to
keep things consistent with BLAKE2s, e.g. by defining
blake2b_compress_arch() which is analogous to blake2s_compress_arch()
and could be exported for use by the library API later if needed.

e9f2289a4b BACKPORT: crypto: blake2b - sync with blake2s implementation
Sync the BLAKE2b code with the BLAKE2s code as much as possible:

- Move a lot of code into new headers <crypto/blake2b.h> and
  <crypto/internal/blake2b.h>, and adjust it to be like the
  corresponding BLAKE2s code, i.e. like <crypto/blake2s.h> and
  <crypto/internal/blake2s.h>.

- Rename constants, e.g. BLAKE2B_*_DIGEST_SIZE => BLAKE2B_*_HASH_SIZE.

- Use a macro BLAKE2B_ALG() to define the shash_alg structs.

- Export blake2b_compress_generic() for use as a fallback.

This makes it much easier to add optimized implementations of BLAKE2b,
as optimized implementations can use the helper functions
crypto_blake2b_{setkey,init,update,final}() and
blake2b_compress_generic().  The ARM implementation will use these.

But this change is also helpful because it eliminates unnecessary
differences between the BLAKE2b and BLAKE2s code, so that the same
improvements can easily be made to both.  (The two algorithms are
basically identical, except for the word size and constants.)  It also
makes it straightforward to add a library API for BLAKE2b in the future
if/when it's needed.

This change does make the BLAKE2b code slightly more complicated than it
needs to be, as it doesn't actually provide a library API yet.  For
example, __blake2b_update() doesn't really need to exist yet; it could
just be inlined into crypto_blake2b_update().  But I believe this is
outweighed by the benefits of keeping the code in sync.

1afd413cae UPSTREAM: crypto: arm/blake2s - add ARM scalar optimized BLAKE2s
Add an ARM scalar optimized implementation of BLAKE2s.

NEON isn't very useful for BLAKE2s because the BLAKE2s block size is too
small for NEON to help.  Each NEON instruction would depend on the
previous one, resulting in poor performance.

With scalar instructions, on the other hand, we can take advantage of
ARM's "free" rotations (like I did in chacha-scalar-core.S) to get an
implementation get runs much faster than the C implementation.

Performance results on Cortex-A7 in cycles per byte using the shash API:

	4096-byte messages:
		blake2s-256-arm:     18.8
		blake2s-256-generic: 26.0

	500-byte messages:
		blake2s-256-arm:     20.3
		blake2s-256-generic: 27.9

	100-byte messages:
		blake2s-256-arm:     29.7
		blake2s-256-generic: 39.2

	32-byte messages:
		blake2s-256-arm:     50.6
		blake2s-256-generic: 66.2

Except on very short messages, this is still slower than the NEON
implementation of BLAKE2b which I've written; that is 14.0, 16.4, 25.8,
and 76.1 cpb on 4096, 500, 100, and 32-byte messages, respectively.
However, optimized BLAKE2s is useful for cases where BLAKE2s is used
instead of BLAKE2b, such as WireGuard.

This new implementation is added in the form of a new module
blake2s-arm.ko, which is analogous to blake2s-x86_64.ko in that it
provides blake2s_compress_arch() for use by the library API as well as
optionally register the algorithms with the shash API.

e13d2476a6 UPSTREAM: crypto: blake2s - optimize blake2s initialization
If no key was provided, then don't waste time initializing the block
buffer, as its initial contents won't be used.

Also, make crypto_blake2s_init() and blake2s() call a single internal
function __blake2s_init() which treats the key as optional, rather than
conditionally calling blake2s_init() or blake2s_init_key().  This
reduces the compiled code size, as previously both blake2s_init() and
blake2s_init_key() were being inlined into these two callers, except
when the key size passed to blake2s() was a compile-time constant.

These optimizations aren't that significant for BLAKE2s.  However, the
equivalent optimizations will be more significant for BLAKE2b, as
everything is twice as big in BLAKE2b.  And it's good to keep things
consistent rather than making optimizations for BLAKE2b but not BLAKE2s.

4af17e1312 BACKPORT: crypto: blake2s - share the "shash" API boilerplate code
Add helper functions for shash implementations of BLAKE2s to
include/crypto/internal/blake2s.h, taking advantage of
__blake2s_update() and __blake2s_final() that were added by the previous
patch to share more code between the library and shash implementations.

crypto_blake2s_setkey() and crypto_blake2s_init() are usable as
shash_alg::setkey and shash_alg::init directly, while
crypto_blake2s_update() and crypto_blake2s_final() take an extra
'blake2s_compress_t' function pointer parameter.  This allows the
implementation of the compression function to be overridden, which is
the only part that optimized implementations really care about.

The new functions are inline functions (similar to those in sha1_base.h,
sha256_base.h, and sm3_base.h) because this avoids needing to add a new
module blake2s_helpers.ko, they aren't *too* long, and this avoids
indirect calls which are expensive these days.  Note that they can't go
in blake2s_generic.ko, as that would require selecting CRYPTO_BLAKE2S
from CRYPTO_BLAKE2S_X86, which would cause a recursive dependency.

Finally, use these new helper functions in the x86 implementation of
BLAKE2s.  (This part should be a separate patch, but unfortunately the
x86 implementation used the exact same function names like
"crypto_blake2s_update()", so it had to be updated at the same time.)

45e0eb38e5 UPSTREAM: crypto: blake2b - Fix clang optimization for ARMv7-M
When building for ARMv7-M, clang-9 or higher tries to unroll some loops,
which ends up confusing the register allocator to the point of generating
rather bad code and using more than the warning limit for stack frames:

warning: stack frame size of 1200 bytes in function 'blake2b_compress' [-Wframe-larger-than=]

Forcing it to not unroll the final loop avoids this problem.

The TFM context can be renamed to a more appropriate name and the local

'mctx'.

The _setkey callback was the last one without the blake2b_ prefix,

5ecbb9a584 UPSTREAM: crypto: blake2b - simplify key init
The keyed init writes the key bytes to the input buffer and does an
update. We can do that in two ways: fill the buffer and update
immediatelly. This is what current blake2b_init_key does. Any other
following _update or _final will continue from the updated state.

The other way is to write the key and set the number of bytes to process
at the next _update or _final, lazy evaluation. Which leads to the the
simplified code in this patch.

92071d4ceb UPSTREAM: crypto: blake2b - merge blake2 init to api callback
The call chain from blake2b_init can be simplified because the param
block is effectively zeros, besides the key.

- blake2b_init0 zeroes state and sets IV
- blake2b_init sets up param block with defaults (key and some 1s)
- init with key, write it to the input buffer and recalculate state

So the compact way is to zero out the state and initialize index 0 of
the state directly with the non-zero values and the key.

edb90dfdf1 BACKPORT: crypto: testmgr - add test vectors for blake2b
Test vectors for blake2b with various digest sizes. As the algorithm is
the same up to the digest calculation, the key and input data length is
distributed in a way that tests all combinanions of the two over the
digest sizes.

Based on the suggestion from Eric, the following input sizes are tested
[0, 1, 7, 15, 64, 247, 256], where blake2b blocksize is 128, so the
padded and the non-padded input buffers are tested.

          blake2b-160  blake2b-256  blake2b-384  blake2b-512
         ---------------------------------------------------
len=0   | klen=0       klen=1       klen=32      klen=64
len=1   | klen=32      klen=64      klen=0       klen=1
len=7   | klen=64      klen=0       klen=1       klen=32
len=15  | klen=1       klen=32      klen=64      klen=0
len=64  | klen=0       klen=1       klen=32      klen=64
len=247 | klen=32      klen=64      klen=0       klen=1
len=256 | klen=64      klen=0       klen=1       klen=32

Where key:

- klen=0: empty key
- klen=1: 1 byte value 0x42, 'B'
- klen=32: first 32 bytes of the default key, sequence 00..1f
- klen=64: default key, sequence 00..3f

The unkeyed vectors are ordered before keyed, as this is required by
testmgr.

e4c224108b BACKPORT: crypto: blake2b - add blake2b generic implementation
The patch brings support of several BLAKE2 variants (2b with various
digest lengths).  The keyed digest is supported, using tfm->setkey call.
The in-tree user will be btrfs (for checksumming), we're going to use
the BLAKE2b-256 variant.

The code is reference implementation taken from the official sources and
modified in terms of kernel coding style (whitespace, comments, uintXX_t
-> uXX types, removed unused prototypes and #ifdefs, removed testing
code, changed secure_zero_memory -> memzero_explicit, used own helpers
for unaligned reads/writes and rotations).

Further changes removed sanity checks of key length or output size,
these values are verified in the crypto API callbacks or hardcoded in
shash_alg and not exposed to users.

eaa8097fa6 mqprio: Correct stats in mqprio_dump_class_stats().
commit 1413269086 upstream.

Introduction of lockless subqueues broke the class statistics.
Before the change stats were accumulated in `bstats' and `qstats'
on the stack which was then copied to struct gnet_dump.

After the change the `bstats' and `qstats' are initialized to 0
and never updated, yet still fed to gnet_dump. The code updates
the global qdisc->cpu_bstats and qdisc->cpu_qstats instead,
clobbering them. Most likely a copy-paste error from the code in
mqprio_dump().

__gnet_stats_copy_basic() and __gnet_stats_copy_queue() accumulate
the values for per-CPU case but for global stats they overwrite
the value, so only stats from the last loop iteration / tc end up
in sch->[bq]stats.

Use the on-stack [bq]stats variables again and add the stats manually
in the global case.

6560d144c4 platform/mellanox: mlxreg-io: Fix argument base in kstrtou32() call
commit 9b02420169 upstream.

Change kstrtou32() argument 'base' to be zero instead of 'len'.
It works by chance for setting one bit value, but it is not supposed to
work in case value passed to mlxreg_io_attr_store() is greater than 1.

It works for example, for:
echo 1 > /sys/devices/platform/mlxplat/mlxreg-io/hwmon/.../jtag_enable
But it will fail for:
echo n > /sys/devices/platform/mlxplat/mlxreg-io/hwmon/.../jtag_enable,
where n > 1.

The flow for input buffer conversion is as below:
_kstrtoull(const char *s, unsigned int base, unsigned long long *res)
calls:
rv = _parse_integer(s, base, &_res);

For the second case, where n > 1:
- _parse_integer() converts 's' to 'val'.
  For n=2, 'len' is set to 2 (string buffer is 0x32 0x0a), for n=3
  'len' is set to 3 (string buffer 0x33 0x0a), etcetera.
- 'base' is equal or greater then '2' (length of input buffer).

As a result, _parse_integer() exits with result zero (rv):
	rv = 0;
	while (1) {
		...
		if (val >= base)-> (2 >= 2)
			break;
		...
		rv++;
		...
	}

And _kstrtoull() in their turn will fail:
	if (rv == 0)
		return -EINVAL;

a3999758c3 ethernet: s2io: fix setting mac address during resume
commit 40507e7aad upstream.

After recent cleanups, gcc started warning about a suspicious
memcpy() call during the s2io_io_resume() function:

In function '__dev_addr_set',
    inlined from 'eth_hw_addr_set' at include/linux/etherdevice.h:318:2,
    inlined from 's2io_set_mac_addr' at drivers/net/ethernet/neterion/s2io.c:5205:2,
    inlined from 's2io_io_resume' at drivers/net/ethernet/neterion/s2io.c:8569:7:
arch/x86/include/asm/string_32.h:182:25: error: '__builtin_memcpy' accessing 6 bytes at offsets 0 and 2 overlaps 4 bytes at offset 2 [-Werror=restrict]
  182 | #define memcpy(t, f, n) __builtin_memcpy(t, f, n)
      |                         ^~~~~~~~~~~~~~~~~~~~~~~~~
include/linux/netdevice.h:4648:9: note: in expansion of macro 'memcpy'
 4648 |         memcpy(dev->dev_addr, addr, len);
      |         ^~~~~~

What apparently happened is that an old cleanup changed the calling
conventions for s2io_set_mac_addr() from taking an ethernet address
as a character array to taking a struct sockaddr, but one of the
callers was not changed at the same time.

Change it to instead call the low-level do_s2io_prog_unicast() function
that still takes the old argument type.

The crc32_le() call comes through the ether_crc_le() call in
arc_emac_set_rx_mode().

[v2: moved the select to ARC_EMAC_CORE; the Makefile is a bit confusing,
but the error comes from emac_main.o, which is part of the arc_emac module,
which in turn is enabled by CONFIG_ARC_EMAC_CORE. Note that arc_emac is
different from emac_arc...]

c57fdeff69 sctp: account stream padding length for reconf chunk
commit a2d859e3fc upstream.

sctp_make_strreset_req() makes repeated calls to sctp_addto_chunk()
which will automatically account for padding on each call. inreq and
outreq are already 4 bytes aligned, but the payload is not and doing
SCTP_PAD4(a + b) (which _sctp_make_chunk() did implicitly here) is
different from SCTP_PAD4(a) + SCTP_PAD4(b) and not enough. It led to
possible attempt to use more buffer than it was allocated and triggered
a BUG_ON.
