7740bd51ef crypto: nx - don't abuse blkcipher_desc to pass iv around
The NX crypto driver is using 'struct blkcipher_desc' to pass the IV
around, even for AEADs (for which it creates the struct on the stack).
This is not appropriate since this structure is part of the "blkcipher"
API, which is deprecated and will be removed.

Just pass around the IV directly instead.

4549f7e5aa crypto: geode-aes - convert to skcipher API and make thread-safe
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.

0fc5deae03 KVM: SVM: Remove unneeded WBINVD and DF_FLUSH when starting SEV guests
Performing a WBINVD and DF_FLUSH are expensive operations. The SEV support
currently performs this WBINVD/DF_FLUSH combination when an SEV guest is
terminated, so there is no need for it to be done before LAUNCH.

However, when the SEV firmware transitions the platform from UNINIT state
to INIT state, all ASIDs will be marked invalid across all threads.
Therefore, as part of transitioning the platform to INIT state, perform a
WBINVD/DF_FLUSH after a successful INIT in the PSP/SEV device driver.
Since the PSP/SEV device driver is x86 only, it can reference and use the
WBINVD related functions directly.

504582e8e4 crypto: geode-aes - switch to skcipher for cbc(aes) fallback
Commit 79c65d179a ("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.

86ef1dfcb5 crypto: atmel-aes - Fix IV handling when req->nbytes < ivsize
commit 394a9e0447 ("crypto: cfb - add missing 'chunksize' property")
adds a test vector where the input length is smaller than the IV length
(the second test vector). This revealed a NULL pointer dereference in
the atmel-aes driver, that is caused by passing an incorrect offset in
scatterwalk_map_and_copy() when atmel_aes_complete() is called.

Do not save the IV in req->info of ablkcipher_request (or equivalently
req->iv of skcipher_request) when req->nbytes < ivsize, because the IV
will not be further used.

While touching the code, modify the type of ivsize from int to
unsigned int, to comply with the return type of
crypto_ablkcipher_ivsize().

977da0738f crypto: inside-secure - Remove #ifdef checks
When both PCI and OF are disabled, no drivers are registered, and
we get some unused-function warnings:

drivers/crypto/inside-secure/safexcel.c:1221:13: error: unused function 'safexcel_unregister_algorithms' [-Werror,-Wunused-function]
static void safexcel_unregister_algorithms(struct safexcel_crypto_priv *priv)

drivers/crypto/inside-secure/safexcel.c:1531:13: error: unused function 'safexcel_hw_reset_rings' [-Werror,-Wunused-function]
static void safexcel_hw_reset_rings(struct safexcel_crypto_priv *priv)

It's better to make the compiler see what is going on and remove
such ifdef checks completely. In case of PCI, this is trivial since
pci_register_driver() is defined to an empty function that makes the
compiler subsequently drop all unused code silently.

The global pcireg_rc/ofreg_rc variables are not actually needed here
since the driver registration does not fail in ways that would make
it helpful.

For CONFIG_OF, an IS_ENABLED() check is still required, since platform
drivers can exist both with and without it.

A little change to linux/pci.h is needed to ensure that
pcim_enable_device() is visible to the driver. Moving the declaration
outside of ifdef would be sufficient here, but for consistency with the
rest of the file, adding an inline helper is probably best.

74e6bd472b crypto: inside-secure - Fix a maybe-uninitialized warning

it with a slightly scarier warning:

drivers/crypto/inside-secure/safexcel.c:1100:6: error: variable 'irq' is used uninitialized whenever 'if' condition is false [-Werror,-Wsometimes-uninitialized]

This is harmless as it is impossible to get into this case, but
the compiler has no way of knowing that. Add an explicit error
handling case to make it obvious to both compilers and humans
reading the source.

using memcpy_toio. What I also noticed is that the mmio store
(either one) is not endian-safe, this will only work on little-
endian configurations, so I also add a Kconfig dependency on
that, regardless of the architecture.
Finally, a depenndecy on CONFIG_64BIT is needed because of the
writeq().

b8c5d882c8 crypto: inside-secure - Fix stability issue with Macchiatobin
This patch corrects an error in the Transform Record Cache initialization
code that was causing intermittent stability problems on the Macchiatobin
board.

Unfortunately, due to HW platform specifics, the problem could not happen
on the main development platform, being the VCU118 Xilinx development
board. And since it was a problem with hash table access, it was very
dependent on the actual physical context record DMA buffers being used,
i.e. with some (bad) luck it could seemingly work quit stable for a while.

This patch adds support for the authenc(hmac(sha1),cbc(sm4)),
authenc(hmac(sm3),cbc(sm4)), authenc(hmac(sha1),rfc3686(ctr(sm4))),
and authenc(hmac(sm3),rfc3686(ctr(sm4))) aead ciphersuites.
These are necessary to support IPsec according to the Chinese standard
GM/T 022-1014 - IPsec VPN specification.

Note that there are no testvectors present in testmgr for these
ciphersuites. However, considering all building blocks have already been
verified elsewhere, it is fair to assume the generic implementation to be
correct-by-construction.
The hardware implementation has been fuzzed against this generic
implementation by means of a locally modified testmgr. The intention is
to upstream these testmgr changes but this is pending other testmgr changes
being made by Eric Biggers.

The patch has been tested with the eip197c_iewxkbc configuration on the
Xilinx VCU118 development board, using the abovementioned modified testmgr

This patch applies on top of "Add support for SM4 ciphers" and needs to
be applied before "Add (HMAC) SHA3 support".

a60619211d crypto: inside-secure - Add support for the Chacha20-Poly1305 AEAD
This patch adds support for the Chacha20-Poly1305 cipher suite.
It adds both the basic rfc7539(chacha20,poly1305) as well as the
rfc7539esp(chacha20,poly1305) variant for IPsec ESP acceleration.

changes since v1:
- rebased on top of DES library changes done on cryptodev/master
- fixed crypto/Kconfig so that generic fallback is compiled as well

changes since v2:
- nothing

changes since v3:
- Fixed a problem where the tcrypt performance test would run fully on the
  fallback cipher instead of the HW due to using an AAD length of 8 for
  rfc7539esp. While this is not actually legal ESP (which includes SPI and
  sequence number in the AAD as well), it is both inconvenient and not
  necessary to run these vectors on the fallback cipher.
- Due to above, also realised that for plain (non-ESP) rfc7539, you
  probably want to be able to run vectors with less than 8 bytes of AAD
  on the HW, and this is actually possible as long as cryptlen is large
  enough, so made that possible as well.

24fbf7bad8 crypto: hisilicon - Fix double free in sec_free_hw_sgl()
There are two problems in sec_free_hw_sgl():

First, when sgl_current->next is valid, @hw_sgl will be freed in the
first loop, but it free again after the loop.

Second, sgl_current and sgl_current->next_sgl is not match when
dma_pool_free() is invoked, the third parameter should be the dma
address of sgl_current, but sgl_current->next_sgl is the dma address
of next chain, so use sgl_current->next_sgl is wrong.

Fix this by deleting the last dma_pool_free() in sec_free_hw_sgl(),
modifying the condition for while loop, and matching the address for
dma_pool_free().

796114f5c5 crypto: caam - make sure clocks are enabled first
In order to access IP block's registers we need to enable appropriate
clocks first, otherwise we are risking hanging the CPU.

The problem becomes very apparent when trying to use CAAM driver built
as a kernel module. In that case caam_probe() gets called after
clk_disable_unused() which means all of the necessary clocks are
guaranteed to be disabled.

Coincidentally, this change also fixes iomap leak introduced by early
return (instead of "goto iounmap_ctrl") in commit
41fc54afae70 ("crypto: caam - simplfy clock initialization")

Since the ccp driver already has a fallback skcipher standby for
dealing with input sizes other than [16, 512, 1024, 2048, 4096],
just drop the check against the block size.

9f5db8b5ea crytpo: caam - make use of iowrite64*_hi_lo in wr_reg64
In order to be able to unify 64 and 32 bit implementations of
wr_reg64, let's convert it to use helpers from
<linux/io-64-nonatomic-hi-lo.h> first. Here are the steps of the
transformation:

1. Inline wr_reg32 helpers:

	if (!caam_imx && caam_little_end) {
		if (caam_little_end) {
			iowrite32(data >> 32, (u32 __iomem *)(reg) + 1);
			iowrite32(data, (u32 __iomem *)(reg));
		} else {
			iowrite32be(data >> 32, (u32 __iomem *)(reg) + 1);
			iowrite32be(data, (u32 __iomem *)(reg));
		}
	} else {
		if (caam_little_end) {
			iowrite32(data >> 32, (u32 __iomem *)(reg));
			iowrite32(data, (u32 __iomem *)(reg) + 1);
		} else {
			iowrite32be(data >> 32, (u32 __iomem *)(reg));
			iowrite32be(data, (u32 __iomem *)(reg) + 1);
		}
	}

2. Transfrom the conditionals such that the check for
'caam_little_end' is at the top level:

	if (caam_little_end) {
		if (!caam_imx) {
			iowrite32(data >> 32, (u32 __iomem *)(reg) + 1);
			iowrite32(data, (u32 __iomem *)(reg));
		} else {
			iowrite32(data >> 32, (u32 __iomem *)(reg));
			iowrite32(data, (u32 __iomem *)(reg) + 1);
		}
	} else {
		iowrite32be(data >> 32, (u32 __iomem *)(reg));
		iowrite32be(data, (u32 __iomem *)(reg) + 1);
	}

3. Invert the check for !caam_imx:

	if (caam_little_end) {
		if (caam_imx) {
			iowrite32(data >> 32, (u32 __iomem *)(reg));
			iowrite32(data, (u32 __iomem *)(reg) + 1);
		} else {
			iowrite32(data >> 32, (u32 __iomem *)(reg) + 1);
			iowrite32(data, (u32 __iomem *)(reg));
		}
	} else {
		iowrite32be(data >> 32, (u32 __iomem *)(reg));
		iowrite32be(data, (u32 __iomem *)(reg) + 1);
	}

4. Make use of iowrite64* helpers from <linux/io-64-nonatomic-hi-lo.h>

	if (caam_little_end) {
		if (caam_imx) {
			iowrite32(data >> 32, (u32 __iomem *)(reg));
			iowrite32(data, (u32 __iomem *)(reg) + 1);
		} else {
			iowrite64(data, reg);
		}
	} else {
		iowrite64be(data, reg);
	}

No functional change intended.

f6cc45c854 crypto: inside-secure - add support for using the EIP197 without vendor firmware
Until now, the inside-secure driver required a set of firmware images
supplied by the silicon vendor, typically under NDA, to be present in
/lib/firmware/inside-secure in order to be able to function.
This patch removes the dependence on this official vendor firmware by
falling back to generic "mini" FW - developed specifically for this
driver - that can be provided under GPL 2.0 through linux-firmwares.

This patch adds support for a PCIE development board with FPGA from Xilinx,
to facilitate pre-silicon driver development by both Inside Secure and its
IP customers. Since Inside Secure neither produces nor has access to actual
silicon, this is required functionality to allow us to contribute.

70e39e2259 crypto: inside-secure - Remove redundant algo to engine mapping code
This removes some code determine which engine has which algorithms which
was effectively redundant (may have been forward-looking?) due to always
enabling all algorithms for all currently supported engines.
A future patch will use a different, more scalable approach to achieve
this. This is removed now because otherwise the next patch will add new
hardware which would otherwise have to be added to all algorithms, so
now is a convenient time to just get rid of this.

0f6e5c8234 crypto: inside-secure - make driver selectable for non-Marvell hardware
While being a generic EIP97/EIP197 driver, the driver was only selectable
for Marvell Armada hardware. This fix makes the driver selectable for any
Device Tree supporting kernel configuration, allowing it to be used for
other compatible hardware by just adding the correct device tree entry.

It also allows the driver to be selected for PCI(E) supporting kernel con-
figurations, to be able to use it with PCIE based FPGA development boards
for pre-silicon driver development by both Inside Secure and its IP custo-
mers.

84a0b00aa4 crypto: s5p - deal gracefully with bogus input sizes
The s5p skcipher driver returns -EINVAL for zero length inputs, which
deviates from the behavior of the generic ECB template, and causes fuzz
tests to fail. In cases where the input is not a multiple of the AES
block size (and the chaining mode is not CTR), it prints an error to
the kernel log, which is a thing we usually try to avoid in response
to situations that can be triggered by unprivileged users.

For correctness and compliance with the XTS-AES specification, we are

though no use cases are known that will be enabled by this.

Since the Power8 implementation already has a fallback skcipher standby
for other purposes, let's use it for this purpose as well. If ciphertext
stealing use cases ever become a bottleneck, we can always revisit this.

This will also permit the cipher interface to be made private to the

ccp-dev.h uses dma_direction, which is defined in linux/dma-direction.h.
Include that explicitly instead of relying on it being included via
linux/pci.h, since ccp-dev.h requires nothing else from linux/pci.h.

Similarly, ccp-dmaengine.c uses dma_get_mask(), which is defined in
linux/dma-mapping.h, so include that explicitly since it requires nothing
else from linux/pci.h.

A future patch will remove the includes of linux/pci.h where it is not

4e3a61c55b crypto: caam - execute module exit point only if necessary
Commit 1b46c90c8e ("crypto: caam - convert top level drivers to libraries")
changed entry and exit points behavior for caamalg,
caamalg_qi, caamalg_qi2, caamhash, caampkc, caamrng.

For example, previously caam_pkc_init() and caam_pkc_exit() were
module entry/exit points. This means that if an error would happen
in caam_pkc_init(), then caam_pkc_exit() wouldn't have been called.
After the mentioned commit, caam_pkc_init() and caam_pkc_exit()
are manually called - from jr.c. caam_pkc_exit() is called
unconditionally, even if caam_pkc_init() failed.

Added a global variable to keep the status of the algorithm
registration and free of resources.
The exit point of caampkc/caamrng module is executed only if the
registration was successful. Therefore we avoid double free of
resources in case the algorithm registration failed.

e9b4913a5f crypto: caam - fix MDHA key derivation for certain user key lengths
Fuzz testing uncovered an issue when |user key| > |derived key|.
Derived key generation has to be fixed in two cases:

1. Era >= 6 (DKP is available)
DKP cannot be used with immediate input key if |user key| > |derived key|,
since the resulting descriptor (after DKP execution) would be invalid -
having a few bytes from user key left in descriptor buffer
as incorrect opcodes.

Fix DKP usage both in standalone hmac and in authenc algorithms.
For authenc the logic is simplified, by always storing both virtual
and dma key addresses.

2. Era < 6
The same case (|user key| > |derived key|) fails when DKP
is not available.
Make sure gen_split_key() dma maps max(|user key|, |derived key|),
since this is an in-place (bidirectional) operation.

ERN handler calls the caam/qi frontend "done" callback with a status
of -EIO. This is incorrect, since the callback expects a status value
meaningful for the crypto engine - hence the cryptic messages
like the one below:
platform caam_qi: 15: unknown error source

Fix this by providing the callback with:
-the status returned by the crypto engine (fd[status]) in case
it contains an error, OR
-a QI "No error" code otherwise; this will trigger the message:
platform caam_qi: 50000000: Queue Manager Interface: No error
which is fine, since QMan driver provides details about the cause of
failure

1bfaac7c53 crypto: inside-secure - Remove redundant DES ECB & CBC keysize check
This patch removes a DES key size check that is redundant as it is already

48f89d2a29 crypto: caam - fix concurrency issue in givencrypt descriptor
IV transfer from ofifo to class2 (set up at [29][30]) is not guaranteed

If ofifo -> external memory transfer happens first, DECO will hang
(issuing a Watchdog Timeout error, if WDOG is enabled) waiting for
data availability in ofifo for the ofifo -> c2 ififo transfer.

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

6ed01097f4 crypto: caam/qi2 - Increase napi budget to process more caam responses
While running ipsec processing for traffic through multiple network
interfaces, it is observed that caam driver gets less time to poll
responses from caam block compared to ethernet driver. This is because
ethernet driver has as many napi instances per cpu as the number of
ethernet interfaces in system. Therefore, caam driver's napi executes
lesser than the ethernet driver's napi instances. This results in
situation that we end up submitting more requests to caam (which it is
able to finish off quite fast), but don't dequeue the responses at same
rate. This makes caam response FQs bloat with large number of frames. In
some situations, it makes kernel crash due to out-of-memory. To prevent
it We increase the napi budget of dpseci driver to a big value so that
caam driver is able to drain its response queues at enough rate.

72c8117adf crypto: ccp - Reduce maximum stack usage
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.

kmemdup is introduced to duplicate a region of memory in a neat way.
Rather than kmalloc/kzalloc + memcpy, which the programmer needs to
write the size twice (sometimes lead to mistakes), kmemdup improves
readability, leads to smaller code and also reduce the chances of mistakes.
Suggestion to use kmemdup rather than using kmalloc/kzalloc + memcpy.

This patch fixes an issue with hash and HMAC operations that perform
"large" intermediate updates (i.e. combined size > 2 hash blocks) by
actually making use of the hardware's hash continue capabilities.
The original implementation would cache these updates in a buffer that
was 2 hash blocks in size and fail if all update calls combined would
overflow that buffer. Which caused the cryptomgr extra tests to fail.

5bdb6e6aa5 crypto: inside-secure - fix incorrect skcipher output IV
This patch fixes corruption issues with the skcipher output IV
witnessed on x86+EIP197-FPGA (devboard). The original fix, commit
57660b11d5 ("crypto: inside-secure - implement IV retrieval"),
attempted to write out the result IV through the context record.
However, this is not a reliable mechanism as there is no way of
knowing the hardware context update actually arrived in memory, so
it is possible to read the old contents instead of the updated IV.
(and indeed, this failed for the x86/FPGA case)

The alternative approach used here recognises the fact that the
result IV for CBC is actually the last cipher block, which is the last
input block in case of decryption and the last output block in case
of encryption. So the result IV is taken from the input data buffer
respectively the output data buffer instead, which *is* reliable.

         40 writers, Iterations Min/Mean/Max = 94,466/95,845/97,098"

     There's a lot of changes to the locking implementation that makes
     it similar to qrwlock, including owner handoff for more fair
     locking.

     Another microbenchmark shows how across the spectrum the
     improvements are:

       "With a locking microbenchmark running on 5.1 based kernel, the
        total locking rates (in kops/s) on a 2-socket Skylake system
        with equal numbers of readers and writers (mixed) before and
        after this patchset were:

        # of Threads   Before Patch      After Patch
        ------------   ------------      -----------
             2            2,618             4,193
             4            1,202             3,726
             8              802             3,622
            16              729             3,359
            32              319             2,826
            64              102             2,744"

     The changes are extensive and the patch-set has been through
     several iterations addressing various locking workloads. There
     might be more regressions, but unless they are pathological I
     believe we want to use this new implementation as the baseline
     going forward.

   - jump-label optimizations by Daniel Bristot de Oliveira: the primary
     motivation was to remove IPI disturbance of isolated RT-workload
     CPUs, which resulted in the implementation of batched jump-label
     updates. Beyond the improvement of the real-time characteristics
     kernel, in one test this patchset improved static key update
     overhead from 57 msecs to just 1.4 msecs - which is a nice speedup
     as well.

   - atomic64_t cross-arch type cleanups by Mark Rutland: over the last
     ~10 years of atomic64_t existence the various types used by the
     APIs only had to be self-consistent within each architecture -
     which means they became wildly inconsistent across architectures.
     Mark puts and end to this by reworking all the atomic64
     implementations to use 's64' as the base type for atomic64_t, and
     to ensure that this type is consistently used for parameters and
     return values in the API, avoiding further problems in this area.

   - A large set of small improvements to lockdep by Yuyang Du: type
     cleanups, output cleanups, function return type and othr cleanups
     all around the place.

   - A set of percpu ops cleanups and fixes by Peter Zijlstra.

   - Misc other changes - please see the Git log for more details"

58cdbc6d22 crypto: talitos - fix hash on SEC1.
On SEC1, hash provides wrong result when performing hashing in several
steps with input data SG list has more than one element. This was
detected with CONFIG_CRYPTO_MANAGER_EXTRA_TESTS:

[   44.185947] alg: hash: md5-talitos test failed (wrong result) on test vector 6, cfg="random: may_sleep use_finup src_divs=[<reimport>25.88%@+8063, <flush>24.19%@+9588, 28.63%@+16333, <reimport>4.60%@+6756, 16.70%@+16281] dst_divs=[71.61%@alignmask+16361, 14.36%@+7756, 14.3%@+"

[   44.493500] alg: hash: sha224-talitos test failed (wrong result) on test vector 4, cfg="random: use_final nosimd src_divs=[<reimport>52.27%@+7401, <reimport>17.34%@+16285, <flush>17.71%@+26, 12.68%@+10644] iv_offset=43"
[   44.673262] alg: hash: sha256-talitos test failed (wrong result) on test vector 4, cfg="random: may_sleep use_finup src_divs=[<reimport>60.6%@+12790, 17.86%@+1329, <reimport>12.64%@alignmask+16300, 8.29%@+15, 0.40%@+13506, <reimport>0.51%@+16322, <reimport>0.24%@+16339] dst_divs"

This is due to two issues:
- We have an overlap between the buffer used for copying the input
data (SEC1 doesn't do scatter/gather) and the chained descriptor.
- Data copy is wrong when the previous hash left less than one
blocksize of data to hash, implying a complement of the previous
block with a few bytes from the new request.

Fix it by:
- Moving the second descriptor after the buffer, as moving the buffer
after the descriptor would make it more complex for other cipher
operations (AEAD, ABLKCIPHER)
- Skip the bytes taken from the new request to complete the previous
one by moving the SG list forward.

8d3bcb9900 crypto: sun4i-ss - reduce stack usage
After the latest addition, the stack usage of sun4i_ss_cipher_poll
grew beyond the warning limit when KASAN is enabled:

drivers/crypto/sunxi-ss/sun4i-ss-cipher.c:118:12: error: stack frame size of 1152 bytes in function 'sun4i_ss_cipher_poll' [-Werror,-Wframe-larger-than=]
static int sun4i_ss_cipher_poll(struct skcipher_request *areq)

Reduce it in three ways:

- split out the new code into a separate function so its stack
  usage can overlap that of the sun4i_ss_opti_poll() code path
- mark both special cases as noinline_for_stack, which should
  ideally result in a tail call that frees the rest of the
  stack
- move the buf and obuf variables into the code blocks in
  which they are used.

The three separate functions now use 144, 640 and 304 bytes of kernel
stack, respectively.

instead of performing the operation in SW.

Besides being more efficient, this also fixes IV update for CTR mode.

Output HW S/G table is appended with an entry pointing to the same
IV buffer used as input (which is now mapped BIDIRECTIONAL).

AS (Algorithm State) parameter of the OPERATION command is changed
from INIFINAL to INIT in descriptors used by ctr(aes), cbc(aes).
This is needed since in case FINAL bit is set, HW skips IV updating
in the Context Register for the last data block.

059d73eea6 crypto: caam - use len instead of nents for bulding HW S/G table
Currently, conversion of SW S/G table into HW S/G layout relies on
nents returned by sg_nents_for_len(sg, len).
However this leaves the possibility of HW S/G referencing more data
then needed: since buffer length in HW S/G entries is filled using
sg_dma_len(sg), the last entry in HW S/G table might have a length
that is bigger than needed for the crypto request.

This way of S/G table conversion is fine, unless after converting a table
more entries have to be appended to the HW S/G table.
In this case, crypto engine would access data from the S/G entry having
the incorrect length, instead of advancing in the S/G table.
This situation doesn't exist, but the upcoming implementation of
IV update for skcipher algorithms needs to add a S/G entry after
req->dst S/G (corresponding to output IV).

1793d1aba1 crypto: qat - use struct_size() helper
One of the more common cases of allocation size calculations is finding
the size of a structure that has a zero-sized array at the end, along
with memory for some number of elements for that array. For example:

struct qat_alg_buf_list {
	...
        struct qat_alg_buf bufers[];
} __packed __aligned(64);

Make use of the struct_size() helper instead of an open-coded version
in order to avoid any potential type mistakes.

So, replace the following form:

sizeof(struct qat_alg_buf_list) + ((1 + n) * sizeof(struct qat_alg_buf))

with:

struct_size(bufl, bufers, n + 1)

This code was detected with the help of Coccinelle.

ed527b13d8 crypto: caam - limit output IV to CBC to work around CTR mode DMA issue
The CAAM driver currently violates an undocumented and slightly
controversial requirement imposed by the crypto stack that a buffer
referred to by the request structure via its virtual address may not
be modified while any scatterlists passed via the same request
structure are mapped for inbound DMA.

This may result in errors like

  alg: aead: decryption failed on test 1 for gcm_base(ctr-aes-caam,ghash-generic): ret=74
  alg: aead: Failed to load transform for gcm(aes): -2

on non-cache coherent systems, due to the fact that the GCM driver
passes an IV buffer by virtual address which shares a cacheline with
the auth_tag buffer passed via a scatterlist, resulting in corruption
of the auth_tag when the IV is updated while the DMA mapping is live.

Since the IV that is returned to the caller is only valid for CBC mode,
and given that the in-kernel users of CBC (such as CTS) don't trigger the
same issue as the GCM driver, let's just disable the output IV generation
for all modes except CBC for the time being.

8933259042 crypto: inside-secure - do not rely on the hardware last bit for result descriptors
When performing a transformation the hardware is given result
descriptors to save the result data. Those result descriptors are
batched using a 'first' and a 'last' bit. There are cases were more
descriptors than needed are given to the engine, leading to the engine
only using some of them, and not setting the last bit on the last
descriptor we gave. This causes issues were the driver and the hardware
aren't in sync anymore about the number of result descriptors given (as
the driver do not give a pool of descriptor to use for any
transformation, but a pool of descriptors to use *per* transformation).

This patch fixes it by attaching the number of given result descriptors
to the requests, and by using this number instead of the 'last' bit
found on the descriptors to process them.

90fde663ae locking/atomic, crypto/nx: Prepare for atomic64_read() conversion
The return type of atomic64_read() varies by architecture. It may return
long (e.g. powerpc), long long (e.g. arm), or s64 (e.g. x86_64). This is
somewhat painful, and mandates the use of explicit casts in some cases
(e.g. when printing the return value).

To ameliorate matters, subsequent patches will make the atomic64 API
consistently use s64.

As a preparatory step, this patch updates the nx-842 code to treat the
return value of atomic64_read() as s64, using explicit casts. These
casts will be removed once the s64 conversion is complete.

da001fb651 crypto: atmel-i2c - add support for SHA204A random number generator
The Linaro/96boards Secure96 mezzanine contains (among other things)
an Atmel SHA204A symmetric crypto processor. This chip implements a
number of different functionalities, but one that is highly useful
for many different 96boards platforms is the random number generator.

So let's implement a driver for the SHA204A, and for the time being,
implement support for the random number generator only.

3c756aa346 crypto: atmel-ecc - add support for ACPI probing on non-AT91 platforms
The Atmel/Microchip EC508A is a I2C device that could be wired into
any platform, and is being used on the Linaro/96boards Secure96
mezzanine adapter. This means it could be found on any platform, even
on ones that use ACPI enumeration (via PRP0001 devices). So update the
code to enable this use case.

This involves tweaking the bus rate discovery code to take ACPI probing
into account, which records the maximum bus rate as a property of the
slave device. For the atmel-ecc code, this means that the effective bus
rate should never exceed the maximum rate, unless we are dealing with
buggy firmware. Nonetheless, let's just use the existing plumbing to
discover the bus rate and keep the existing logic intact.

The CAAM driver used to put its debug messages inside #ifdef DEBUG and
then prints the messages at KERN_ERR level. Replace this with proper
functions printing at KERN_DEBUG level. The #ifdef DEBUG gets
unnecessary when the right functions are used.

This replaces:

- print_hex_dump(KERN_ERR ...) inside #ifdef DEBUG with
  print_hex_dump_debug(...)
- dev_err() inside #ifdef DEBUG with dev_dbg()
- printk(KERN_ERR ...) inside #ifdef DEBUG with dev_dbg()

Some parts of the driver use these functions already, so it is only
consequent to use the debug function consistently.

0f7a813740 crypto: crypto4xx - block ciphers should only accept complete blocks
The hardware automatically zero pads incomplete block ciphers
blocks without raising any errors. This is a screw-up. This
was noticed by CONFIG_CRYPTO_MANAGER_EXTRA_TESTS tests that
sent a incomplete blocks and expect them to fail.

This fixes:
cbc-aes-ppc4xx encryption unexpectedly succeeded on test vector
"random: len=2409 klen=32"; expected_error=-22, cfg="random:
may_sleep use_digest src_divs=[96.90%@+2295, 2.34%@+4066,

ecb-aes-ppc4xx encryption unexpectedly succeeded on test vector
"random: len=1011 klen=32"; expected_error=-22, cfg="random:

70c4997f34 crypto: crypto4xx - fix blocksize for cfb and ofb
While the hardware consider them to be blockciphers, the

Do the right thing and set the blocksize to 1. This
was found by CONFIG_CRYPTO_MANAGER_EXTRA_TESTS.

bfa2ba7d9e crypto: crypto4xx - fix AES CTR blocksize value
This patch fixes a issue with crypto4xx's ctr(aes) that was
discovered by libcapi's kcapi-enc-test.sh test.

The some of the ctr(aes) encryptions test were failing on the
non-power-of-two test:

kcapi-enc - Error: encryption failed with error 0
kcapi-enc - Error: decryption failed with error 0
[FAILED: 32-bit - 5.1.0-rc1+] 15 bytes: STDIN / STDOUT enc test (128 bits):

[FAILED: 32-bit - 5.1.0-rc1+] 15 bytes: STDIN / STDOUT enc test (password):

But the 16, 32, 512, 65536 tests always worked.

Thankfully, this isn't a hidden hardware problem like previously,
instead this turned out to be a copy and paste issue.

With this patch, all the tests are passing with and
kcapi-enc-test.sh gives crypto4xx's a clean bill of health:
 "Number of failures: 0" :).

Currently there is a mismatch b/w the ICID (Isolation Context ID) used
for DMA mapping keys and ICID used for accessing them.
-keys are DMA mapped using a job ring device, thus a job ring ICID
-keys are accessed from descriptors enqueued via Queue Interface,
thus using QI ICID

[Note: ICIDs of JRs, QI are configured by U-boot / other entity by:
-fixing up the corresponding job ring and controller DT nodes
-setting up corresponding caam ICID registers]

In order to avoid IOMMU faults, DMA map the key using the controller
device instead of a job ring device.

1b46c90c8e crypto: caam - convert top level drivers to libraries
Currently we allow top level code, i.e. that which sits between the
low level (HW-specific) drivers and crypto API, to be built as several
drivers: caamalg, caamhash, caam_pkc, caamrng, caamalg_qi.

There is no advantage in this, more it interferes with adding support
for deferred probing (there are no corresponding devices and thus
no bus).

Convert these drivers and call init() / exit() manually at the right
time.
Move algorithms initialization at JR probe / remove time:
-the first probed JR registers the crypto algs
-the last removed JR unregisters the crypto algs

Note: caam_qi_init() is called before JR platform devices creation
(of_populate_bus()), such that QI interface is initialized when
the caam/qi algorithms are registered in the JR driver (by calling
caam_qi_algapi_init().

While here, fix the Kconfig entries under CRYPTO_DEV_FSL_CAAM_JR
to be aligned.

a5e5c13398 crypto: caam - fix S/G table passing page boundary
According to CAAM RM:
-crypto engine reads 4 S/G entries (64 bytes) at a time,
even if the S/G table has fewer entries
-it's the responsibility of the user / programmer to make sure
this HW behaviour has no side effect

The drivers do not take care of this currently, leading to IOMMU faults
when the S/G table ends close to a page boundary - since only one page
is DMA mapped, while CAAM's DMA engine accesses two pages.

Fix this by rounding up the number of allocated S/G table entries
to a multiple of 4.
Note that in case of two *contiguous* S/G tables, only the last table
might needs extra entries.

dcd9c76e5a crypto: caam - avoid S/G table fetching for AEAD zero-length output
When enabling IOMMU support, the following issue becomes visible
in the AEAD zero-length case.

Even though the output sequence length is set to zero, the crypto engine
tries to prefetch 4 S/G table entries (since SGF bit is set
in SEQ OUT PTR command - which is either generated in SW in case of
caam/jr or in HW in case of caam/qi, caam/qi2).
The DMA read operation will trigger an IOMMU fault since the address in
the SEQ OUT PTR is "dummy" (set to zero / not obtained via DMA API
mapping).

1. In case of caam/jr, avoid the IOMMU fault by clearing the SGF bit
in SEQ OUT PTR command.

2. In case of caam/qi - setting address, bpid, length to zero for output
entry in the compound frame has a special meaning (cf. CAAM RM):
"Output frame = Unspecified, Input address = Y. A unspecified frame is
indicated by an unused SGT entry (an entry in which the Address, Length,
and BPID fields are all zero). SEC obtains output buffers from BMan as
prescribed by the preheader."

Since no output buffers are needed, modify the preheader by setting
(ABS = 1, ADDBUF = 0):
-"ABS = 1 means obtain the number of buffers in ADDBUF (0 or 1) from
the pool POOL ID"
-ADDBUF: "If ABS is set, ADD BUF specifies whether to allocate
a buffer or not"

3. In case of caam/qi2, since engine:
-does not support FLE[FMT]=2'b11 ("unused" entry) mentioned in DPAA2 RM
-requires output entry to be present, even if not used
the solution chosen is to leave output frame list entry zeroized.

Here are series of patches that add SPDX tags to different kernel files,
 based on two different things:
   - SPDX entries are added to a bunch of files that we missed a year ago
     that do not have any license information at all.
 
     These were either missed because the tool saw the MODULE_LICENSE()
     tag, or some EXPORT_SYMBOL tags, and got confused and thought the
     file had a real license, or the files have been added since the last
     big sweep, or they were Makefile/Kconfig files, which we didn't
     touch last time.
 
   - Add GPL-2.0-only or GPL-2.0-or-later tags to files where our scan
     tools can determine the license text in the file itself.  Where this
     happens, the license text is removed, in order to cut down on the
     700+ different ways we have in the kernel today, in a quest to get
     rid of all of these.
 
 These patches have been out for review on the linux-spdx@vger mailing
 list, and while they were created by automatic tools, they were
 hand-verified by a bunch of different people, all whom names are on the
 patches are reviewers.
 
 The reason for these "large" patches is if we were to continue to
 progress at the current rate of change in the kernel, adding license
 tags to individual files in different subsystems, we would be finished
 in about 10 years at the earliest.
 
 There will be more series of these types of patches coming over the next
 few weeks as the tools and reviewers crunch through the more "odd"
 variants of how to say "GPLv2" that developers have come up with over
 the years, combined with other fun oddities (GPL + a BSD disclaimer?)
 that are being unearthed, with the goal for the whole kernel to be
 cleaned up.
 
 These diffstats are not small, 3840 files are touched, over 10k lines
 removed in just 24 patches.

357d065a44 crypto: vmx - ghash: do nosimd fallback manually
VMX ghash was using a fallback that did not support interleaving simd
and nosimd operations, leading to failures in the extended test suite.

If I understood correctly, Eric's suggestion was to use the same
data format that the generic code uses, allowing us to call into it
with the same contexts. I wasn't able to get that to work - I think
there's a very different key structure and data layout being used.

So instead steal the arm64 approach and perform the fallback
operations directly if required.

009b30ac74 crypto: vmx - CTR: always increment IV as quadword
The kernel self-tests picked up an issue with CTR mode:
alg: skcipher: p8_aes_ctr encryption test failed (wrong result) on test vector 3, cfg="uneven misaligned splits, may sleep"

Test vector 3 has an IV of FFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFD, so
after 3 increments it should wrap around to 0.

In the aesp8-ppc code from OpenSSL, there are two paths that
increment IVs: the bulk (8 at a time) path, and the individual
path which is used when there are fewer than 8 AES blocks to
process.

In the bulk path, the IV is incremented with vadduqm: "Vector
Add Unsigned Quadword Modulo", which does 128-bit addition.

In the individual path, however, the IV is incremented with
vadduwm: "Vector Add Unsigned Word Modulo", which instead
does 4 32-bit additions. Thus the IV would instead become
FFFFFFFFFFFFFFFFFFFFFFFF00000000, throwing off the result.

Use vadduqm.

This was probably a typo originally, what with q and w being
adjacent. It is a pretty narrow edge case: I am really
impressed by the quality of the kernel self-tests!

7e92e1717e crypto: crypto4xx - fix cfb and ofb "overran dst buffer" issues
Currently, crypto4xx CFB and OFB AES ciphers are
failing testmgr's test vectors.

|cfb-aes-ppc4xx encryption overran dst buffer on test vector 3, cfg="in-place"
|ofb-aes-ppc4xx encryption overran dst buffer on test vector 1, cfg="in-place"

This is because of a very subtile "bug" in the hardware that
gets indirectly mentioned in 18.1.3.5 Encryption/Decryption
of the hardware spec:

the OFB and CFB modes for AES are listed there as operation
modes for >>> "Block ciphers" <<<. Which kind of makes sense,
but we would like them to be considered as stream ciphers just
like the CTR mode.

To workaround this issue and stop the hardware from causing
"overran dst buffer" on crypttexts that are not a multiple
of 16 (AES_BLOCK_SIZE), we force the driver to use the scatter
buffers as the go-between.

As a bonus this patch also kills redundant pd_uinfo->num_gd
and pd_uinfo->num_sd setters since the value has already been
set before.

25baaf8e2c crypto: crypto4xx - fix ctr-aes missing output IV
Commit 8efd972ef9 ("crypto: testmgr - support checking skcipher output IV")
caused the crypto4xx driver to produce the following error:

| ctr-aes-ppc4xx encryption test failed (wrong output IV)
| on test vector 0, cfg="in-place"

This patch fixes this by reworking the crypto4xx_setkey_aes()
function to:

 - not save the iv for ECB (as per 18.2.38 CRYP0_SA_CMD_0:
   "This bit mut be cleared for DES ECB mode or AES ECB mode,
   when no IV is used.")

 - instruct the hardware to save the generated IV for all
   other modes of operations that have IV and then supply
   it back to the callee in pretty much the same way as we
   do it for cbc-aes already.

 - make it clear that the DIR_(IN|OUT)BOUND is the important
   bit that tells the hardware to encrypt or decrypt the data.
   (this is cosmetic - but it hopefully prevents me from
    getting confused again).

 - don't load any bogus hash when we don't use any hash
   operation to begin with.

df80bfd343 crypto: caam/jr - update gcm detection logic
GCM detection logic has to change for two reasons:
-some CAAM instantiations with Era < 10, even though they have AES LP,
they now support GCM mode
-Era 10 upwards, there is a dedicated bit in AESA_VERSION[AESA_MISC]
field for GCM support

For Era 9 and earlier, all AES accelerator versions support GCM,
except for AES LP (CHAVID_LS[AESVID]=3) with revision CRNR[AESRN] < 8.

For Era 10 and later, bit 9 of the AESA_VERSION register should be used
to detect GCM support in AES accelerator.

Note: caam/qi and caam/qi2 are drivers for QI (Queue Interface), which
is used in DPAA-based SoCs; for now, we rely on CAAM having an AES HP
and this AES accelerator having support for GCM.

877b5691f2 crypto: shash - remove shash_desc::flags
The flags field in 'struct shash_desc' never actually does anything.
The only ostensibly supported flag is CRYPTO_TFM_REQ_MAY_SLEEP.
However, no shash algorithm ever sleeps, making this flag a no-op.

With this being the case, inevitably some users who can't sleep wrongly
pass MAY_SLEEP.  These would all need to be fixed if any shash algorithm
actually started sleeping.  For example, the shash_ahash_*() functions,
which wrap a shash algorithm with the ahash API, pass through MAY_SLEEP
from the ahash API to the shash API.  However, the shash functions are
called under kmap_atomic(), so actually they're assumed to never sleep.

Even if it turns out that some users do need preemption points while
hashing large buffers, we could easily provide a helper function
crypto_shash_update_large() which divides the data into smaller chunks
and calls crypto_shash_update() and cond_resched() for each chunk.  It's
not necessary to have a flag in 'struct shash_desc', nor is it necessary
to make individual shash algorithms aware of this at all.

Therefore, remove shash_desc::flags, and document that the
crypto_shash_*() functions can be called from any context.

75f2222832 crypto: nx - don't abuse shash MAY_SLEEP flag
The nx driver uses the MAY_SLEEP flag in shash_desc::flags as an
indicator to not retry sending the operation to the hardware as many
times before returning -EBUSY.  This is bogus because (1) that's not
what the MAY_SLEEP flag is for, and (2) the shash API doesn't allow
failing if the hardware is busy anyway.

For now, just make it always retry the larger number of times.  This
doesn't actually fix this driver, but it at least makes it not use the
shash_desc::flags field anymore.  Then this field can be removed, as no
other drivers use it.

fb24ea52f7 drivers: Remove explicit invocations of mmiowb()
mmiowb() is now implied by spin_unlock() on architectures that require
it, so there is no reason to call it from driver code. This patch was
generated using coccinelle:

	@mmiowb@
	@@
	- mmiowb();

and invoked as:

$ for d in drivers include/linux/qed sound; do \
spatch --include-headers --sp-file mmiowb.cocci --dir $d --in-place; done

NOTE: mmiowb() has only ever guaranteed ordering in conjunction with
spin_unlock(). However, pairing each mmiowb() removal in this patch with
the corresponding call to spin_unlock() is not at all trivial, so there
is a small chance that this change may regress any drivers incorrectly
relying on mmiowb() to order MMIO writes between CPUs using lock-free
synchronisation. If you've ended up bisecting to this commit, you can
reintroduce the mmiowb() calls using wmb() instead, which should restore
the old behaviour on all architectures other than some esoteric ia64
systems.

The current definition and implementation of the SEV_GET_ID command
does not provide the length of the unique ID returned by the firmware.
As per the firmware specification, the firmware may return an ID
length that is not restricted to 64 bytes as assumed by the SEV_GET_ID
command.

Introduce the SEV_GET_ID2 command to overcome with the SEV_GET_ID
limitations. Deprecate the SEV_GET_ID in the favor of SEV_GET_ID2.

At the same time update SEV API web link.

Some i.MX6 devices (imx6D, imx6Q, imx6DL, imx6S, imx6DP and imx6DQ) have
an issue wherein AXI bus transactions may not occur in the correct order.
This isn't a problem running single descriptors, but can be if running
multiple concurrent descriptors. Reworking the CAAM driver to throttle
to single requests is impractical, so this patch limits the AXI pipeline
to a depth of one (from a default of 4) to preclude this situation from
occurring.
This patch applies to known affected platforms.

In caam_jr_enqueue(), a write barrier is needed to order stores to job
ring slot before declaring addition of new job into input job ring.
The register write is done using wr_reg32() which internally uses
iowrite32() for write operation. The api iowrite32() issues a write
barrier before issuing write operation. Therefore, the wmb() preceding
wr_reg32() can be safely removed.

This leads to corruption of the IV, which leads to subsequent blocks

drivers/crypto/ccree/cc_cipher.c:318:12: error: stack frame size of 1152 bytes in function 'cc_cipher_setkey' [-Werror,-Wframe-larger-than=]

The problem is that there are two large variables: the temporary
'tmp' array and the SHASH_DESC_ON_STACK() declaration. Moving
the first into the block in which it is used reduces the
total frame size to 768 bytes, which seems more reasonable
and is under the warning limit.

Instead of reading job ring's occupancy registers for every req/rsp
enqueued/dequeued respectively, we read these registers once and store
them in memory. After completing a job enqueue/dequeue, we decrement
these values. When these values become zero, we refresh the snapshot of
job ring's occupancy registers. This eliminates need of expensive device
register read operations for every job enqueued and dequeued and hence
makes caam_jr_enqueue() and caam_jr_dequeue() faster. The performance of
kernel ipsec improved by about 6% on ls1028 (for frame size 408 bytes).

7df5218d66 crypto: ccp - Update driver messages to remove some confusion
The current content of some of the driver messages and the way that they
are issued results in some confusion, especially in the area of the PSP
as it relates to SEV support. If SEV is not supported, a message is issued
that says "psp initialization failed." This makes it seem like there was
a problem, when in fact, the PSP support is just disabled if SEV is not
supported.

Update the driver to check SEV support a bit earlier and issue a debug-
level message if SEV is not supported, followed by a debug-level message
that the PSP is disabled. This way you will only see PSP messages if SEV
is supported or if debug information is desired. Also, remove the overall
"enabled" and "disabled" messages for the driver and rely on the CCP and
PSP support to issue component-specific messages.

ac5d15b451 crypto: caam/qi2 - use affine DPIOs
Driver was relying on an older DPIO API, which provided a CPU-affine DPIO
in case it was called with preemption disabled.

Since this is no longer the case, save the CPU-affine DPIO in per-cpu
private structure during setup and further use it on the hot path.

Note that preemption is no longer disabled while trying to enqueue an
FD. Thus it might be possible to run the enqueue on a different CPU
(due to migration, when in process context), however this wouldn't be a
functionality issue.
Since we allow for all cores to enqueue, we take care of data
structures setup to handle the case when number of (Rx, Tx) queue pairs
is smaller than number of cores.

The netfilter conflicts were rather simple overlapping
changes.

However, the cls_tcindex.c stuff was a bit more complex.

On the 'net' side, Cong is fixing several races and memory
leaks.  Whilst on the 'net-next' side we have Vlad adding
the rtnl-ness support.

What I've decided to do, in order to resolve this, is revert the
conversion over to using a workqueue that Cong did, bringing us back
to pure RCU.  I did it this way because I believe that either Cong's
races don't apply with have Vlad did things, or Cong will have to
implement the race fix slightly differently.

1358c13a48 crypto: ccree - fix resume race condition on init
We were enabling autosuspend, which is using data set by the
hash module, prior to the hash module being inited, casuing
a crash on resume as part of the startup sequence if the race
was lost.

This was never a real problem because the PM infra was using low
res timers so we were always winning the race, until commit 8234f6734c
("PM-runtime: Switch autosuspend over to using hrtimers") changed that :-)

Fix this by seperating the PM setup and enablement and doing the
latter only at the end of the init sequence.

The cause is that the struct ahash_request *req is created as a
stack-local variable up in the stack (presumably somewhere in the IMA
implementation), then passed down into the CAAM driver, which tries to
dma_single_map the req->result (indirectly via map_seq_out_ptr_result)
in order to make that buffer available for the CAAM to store the result
of the following hash operation.

The calling code doesn't know how req will be used by the CAAM driver,
and there could be other such occurrences where stack memory is passed
down to the CAAM driver. Therefore we should rather fix this issue in
the CAAM driver where the requirements are known."

Fix this problem by:
-instructing the crypto engine to write the final hash in state->caam_ctx
-subsequently memcpy-ing the final hash into req->result

231baecdef crypto: clarify name of WEAK_KEY request flag
CRYPTO_TFM_REQ_WEAK_KEY confuses newcomers to the crypto API because it
sounds like it is requesting a weak key.  Actually, it is requesting
that weak keys be forbidden (for algorithms that have the notion of
"weak keys"; currently only DES and XTS do).

Also it is only one letter away from CRYPTO_TFM_RES_WEAK_KEY, with which
it can be easily confused.  (This in fact happened in the UX500 driver,
though just in some debugging messages.)

Therefore, make the intent clear by renaming it to
CRYPTO_TFM_REQ_FORBID_WEAK_KEYS.

will ensure that when a DPIO device, which is indirectly used by other
devices, is unbound any consumer devices will be also unbound from their
drivers.

For example, any DPNI, bound to the dpaa2-eth driver, which is using
DPIO devices will be unbound before its supplier device.

Also, add a new parameter to the dpaa2_io_service_[de]register functions
to specify the requesting device (ie the consumer).

There are several issues with symbols shared b/w:
-caam/jr and caam/qi drivers on one hand
-caam/qi2 driver on the other hand

Commit 52813ab249 ("crypto: caam/qi2 - avoid double export") fixed
some of them, however compilation still fails for CRYPTO_DEV_FSL_CAAM=m
and CRYPTO_DEV_FSL_DPAA2_CAAM=y.

Another issue is related to dependency cycles reported by depmod when
CRYPTO_DEV_FSL_CAAM=n and CRYPTO_DEV_FSL_DPAA2_CAAM=m, as mentioned in
82c7b351be ("Revert "arm64: defconfig: Enable FSL_MC_BUS and FSL_MC_DPIO"")

To fix all these, move the symbols shared by these drivers in a common
location. The only existing possibility is error.c file (note that naming
doesn't help and should probably change).

96d4f267e4 Remove 'type' argument from access_ok() function
Nobody has actually used the type (VERIFY_READ vs VERIFY_WRITE) argument
of the user address range verification function since we got rid of the
old racy i386-only code to walk page tables by hand.

It existed because the original 80386 would not honor the write protect
bit when in kernel mode, so you had to do COW by hand before doing any
user access.  But we haven't supported that in a long time, and these
days the 'type' argument is a purely historical artifact.

A discussion about extending 'user_access_begin()' to do the range
checking resulted this patch, because there is no way we're going to
move the old VERIFY_xyz interface to that model.  And it's best done at
the end of the merge window when I've done most of my merges, so let's
just get this done once and for all.

This patch was mostly done with a sed-script, with manual fix-ups for
the cases that weren't of the trivial 'access_ok(VERIFY_xyz' form.

There were a couple of notable cases:

 - csky still had the old "verify_area()" name as an alias.

 - the iter_iov code had magical hardcoded knowledge of the actual
   values of VERIFY_{READ,WRITE} (not that they mattered, since nothing
   really used it)

 - microblaze used the type argument for a debug printout

but other than those oddities this should be a total no-op patch.

I tried to fix up all architectures, did fairly extensive grepping for
access_ok() uses, and the changes are trivial, but I may have missed
something.  Any missed conversion should be trivially fixable, though.

 2) Add ipv4 ttl and tos, plus ipv6 flow label and hop limit offloads to
    nfp driver. From Stefano Brivio.

 3) Implement GRO for plain UDP sockets, from Paolo Abeni.

 4) Lots of work from Michał Mirosław to eliminate the VLAN_TAG_PRESENT
    bit so that we could support the entire vlan_tci value.

 5) Rework the IPSEC policy lookups to better optimize more usecases,
    from Florian Westphal.

 6) Infrastructure changes eliminating direct manipulation of SKB lists
    wherever possible, and to always use the appropriate SKB list
    helpers. This work is still ongoing...

    simplifications, from Heiner Kallweit.

 8) Various TSO deferral refinements, from Eric Dumazet.

 9) Add ntuple filter support to aquantia driver, from Dmitry Bogdanov.

10) Batch dropping of XDP packets in tuntap, from Jason Wang.

11) Lots of cleanups and improvements to the r8169 driver from Heiner

    Shlomo and others.

22) Add a NETDEV_PRE_CHANGEADDR so that drivers can veto the change and
    therefore abort the operation before the commit phase (which is the

c79b411eaa crypto: skcipher - remove remnants of internal IV generators
Remove dead code related to internal IV generators, which are no longer
used since they've been replaced with the "seqiv" and "echainiv"
templates.  The removed code includes:

- The "givcipher" (GIVCIPHER) algorithm type.  No algorithms are
  registered with this type anymore, so it's unneeded.

- The "const char *geniv" member of aead_alg, ablkcipher_alg, and
  blkcipher_alg.  A few algorithms still set this, but it isn't used
  anymore except to show via /proc/crypto and CRYPTO_MSG_GETALG.
  Just hardcode "<default>" or "<none>" in those cases.

- The 'skcipher_givcrypt_request' structure, which is never used.

8636a1f967 treewide: surround Kconfig file paths with double quotes
The Kconfig lexer supports special characters such as '.' and '/' in
the parameter context. In my understanding, the reason is just to
support bare file paths in the source statement.

I do not see a good reason to complicate Kconfig for the room of
ambiguity.

The majority of code already surrounds file paths with double quotes,
and it makes sense since file paths are constant string literals.

Make it treewide consistent now.

67d8208fba crypto4xx_core: don't abuse __dma_sync_page
This function is internal to the DMA API implementation. Instead use
the DMA API to properly unmap. Note that the DMA API usage in this
driver is a disaster and urgently needs some work - it is missing all
the unmaps, seems to do a secondary map where it looks like it should
to a unmap in one place to work around cache coherency and the
directions passed in seem to be partially wrong.

1ca1b91794 crypto: chacha20-generic - refactor to allow varying number of rounds
In preparation for adding XChaCha12 support, rename/refactor
chacha20-generic to support different numbers of rounds.  The
justification for needing XChaCha12 support is explained in more detail
in the patch "crypto: chacha - add XChaCha12 support".

The only difference between ChaCha{8,12,20} are the number of rounds
itself; all other parts of the algorithm are the same.  Therefore,
remove the "20" from all definitions, structures, functions, files, etc.
that will be shared by all ChaCha versions.

Also make ->setkey() store the round count in the chacha_ctx (previously
chacha20_ctx).  The generic code then passes the round count through to
chacha_block().  There will be a ->setkey() function for each explicitly
allowed round count; the encrypt/decrypt functions will be the same.  I
decided not to do it the opposite way (same ->setkey() function for all
round counts, with different encrypt/decrypt functions) because that
would have required more boilerplate code in architecture-specific
implementations of ChaCha and XChaCha.

1ad0f1603a crypto: drop mask=CRYPTO_ALG_ASYNC from 'cipher' tfm allocations
'cipher' algorithms (single block ciphers) are always synchronous, so
passing CRYPTO_ALG_ASYNC in the mask to crypto_alloc_cipher() has no
effect.  Many users therefore already don't pass it, but some still do.
This inconsistency can cause confusion, especially since the way the
'mask' argument works is somewhat counterintuitive.

Thus, just remove the unneeded CRYPTO_ALG_ASYNC flags.

This patch shouldn't change any actual behavior.

Some algorithms initialize their .cra_list prior to registration.
But this is unnecessary since crypto_register_alg() will overwrite

Apparently the useless assignment has just been copy+pasted around.

So, remove the useless assignments.

Exception: paes_s390.c uses cra_list to check whether the algorithm is
registered or not, so I left that as-is for now.

7172122be6 crypto: cavium/nitrox - fix a DMA pool free failure
In crypto_alloc_context(), a DMA pool is allocated through dma_pool_alloc()
to hold the crypto context. The meta data of the DMA pool, including the
pool used for the allocation 'ndev->ctx_pool' and the base address of the
DMA pool used by the device 'dma', are then stored to the beginning of the
pool. These meta data are eventually used in crypto_free_context() to free
the DMA pool through dma_pool_free(). However, given that the DMA pool can
also be accessed by the device, a malicious device can modify these meta
data, especially when the device is controlled to deploy an attack. This
can cause an unexpected DMA pool free failure.

To avoid the above issue, this patch introduces a new structure
crypto_ctx_hdr and a new field chdr in the structure nitrox_crypto_ctx hold
the meta data information of the DMA pool after the allocation. Note that
the original structure ctx_hdr is not changed to ensure the compatibility.

40b06553c9 cxgb4: fix the error path of cxgb4_uld_register()
On multi adapter setup if the uld registration fails even on
one adapter, the allocated resources for the uld on all the
adapters are freed, rendering the functioning adapters unusable.

This commit fixes the issue by freeing the allocated resources
only for the failed adapter.

18e732b803 crypto: ccree - avoid implicit enum conversion
Clang warns when one enumerated type is implicitly converted to another
and this happens in several locations in this driver, ultimately related
to the set_cipher_{mode,config0} functions. set_cipher_mode expects a mode
of type drv_cipher_mode and set_cipher_config0 expects a mode of type
drv_crypto_direction.

drivers/crypto/ccree/cc_ivgen.c:58:35: warning: implicit conversion from
enumeration type 'enum cc_desc_direction' to different enumeration type
'enum drv_crypto_direction' [-Wenum-conversion]
        set_cipher_config0(&iv_seq[idx], DESC_DIRECTION_ENCRYPT_ENCRYPT);

drivers/crypto/ccree/cc_hash.c:99:28: warning: implicit conversion from
enumeration type 'enum cc_hash_conf_pad' to different enumeration type
'enum drv_crypto_direction' [-Wenum-conversion]
                set_cipher_config0(desc, HASH_DIGEST_RESULT_LITTLE_ENDIAN);

drivers/crypto/ccree/cc_aead.c:1643:30: warning: implicit conversion
from enumeration type 'enum drv_hash_hw_mode' to different enumeration
type 'enum drv_cipher_mode' [-Wenum-conversion]
        set_cipher_mode(&desc[idx], DRV_HASH_HW_GHASH);

Since this fundamentally isn't a problem because these values just
represent simple integers for a shift operation, make it clear to Clang
that this is okay by making the mode parameter in both functions an int.

29e83c7570 crypto: caam/qi - simplify CGR allocation, freeing
CGRs (Congestion Groups) have to be freed by the same CPU that
initialized them.
This is why currently the driver takes special measures; however, using
set_cpus_allowed_ptr() is incorrect - as reported by Sebastian.

Instead of the generic solution of replacing set_cpus_allowed_ptr() with
work_on_cpu_safe(), we use the qman_delete_cgr_safe() QBMan API instead
of qman_delete_cgr() - which internally takes care of proper CGR
deletion.

00fab2350e s390/zcrypt: multiple zcrypt device nodes support
This patch is an extension to the zcrypt device driver to provide,
support and maintain multiple zcrypt device nodes. The individual
zcrypt device nodes can be restricted in terms of crypto cards,
domains and available ioctls. Such a device node can be used as a
base for container solutions like docker to control and restrict
the access to crypto resources.

The handling is done with a new sysfs subdir /sys/class/zcrypt.
Echoing a name (or an empty sting) into the attribute "create" creates
a new zcrypt device node. In /sys/class/zcrypt a new link will appear
which points to the sysfs device tree of this new device. The
attribute files "ioctlmask", "apmask" and "aqmask" in this directory
are used to customize this new zcrypt device node instance. Finally
the zcrypt device node can be destroyed by echoing the name into
/sys/class/zcrypt/destroy. The internal structs holding the device
info are reference counted - so a destroy will not hard remove a
device but only marks it as removable when the reference counter drops
to zero.

The mask values are bitmaps in big endian order starting with bit 0.
So adapter number 0 is the leftmost bit, mask is 0x8000...  The sysfs
attributes accept 2 different formats:
* Absolute hex string starting with 0x like "0x12345678" does set
  the mask starting from left to right. If the given string is shorter
  than the mask it is padded with 0s on the right. If the string is
  longer than the mask an error comes back (EINVAL).
* Relative format - a concatenation (done with ',') of the
  terms +<bitnr>[-<bitnr>] or -<bitnr>[-<bitnr>]. <bitnr> may be any
  valid number (hex, decimal or octal) in the range 0...255. Here are
  some examples:
    "+0-15,+32,-128,-0xFF"
    "-0-255,+1-16,+0x128"
    "+1,+2,+3,+4,-5,-7-10"

A simple usage examples:

  # create new zcrypt device 'my_zcrypt':
  echo "my_zcrypt" >/sys/class/zcrypt/create
  # go into the device dir of this new device
  echo "my_zcrypt" >create
  cd my_zcrypt/
  ls -l
  total 0
  -rw-r--r-- 1 root root 4096 Jul 20 15:23 apmask
  -rw-r--r-- 1 root root 4096 Jul 20 15:23 aqmask
  -r--r--r-- 1 root root 4096 Jul 20 15:23 dev
  -rw-r--r-- 1 root root 4096 Jul 20 15:23 ioctlmask
  lrwxrwxrwx 1 root root    0 Jul 20 15:23 subsystem -> ../../../../class/zcrypt
  ...
  # customize this zcrypt node clone
  # enable only adapter 0 and 2
  echo "0xa0" >apmask
  # enable only domain 6
  echo "+6" >aqmask
  # enable all 256 ioctls
  echo "+0-255" >ioctls
  # now the /dev/my_zcrypt may be used
  # finally destroy it
  echo "my_zcrypt" >/sys/class/zcrypt/destroy

Please note that a very similar 'filtering behavior' also applies to
the parent z90crypt device. The two mask attributes apmask and aqmask
in /sys/bus/ap act the very same for the z90crypt device node. However
the implementation here is totally different as the ap bus acts on
bind/unbind of queue devices and associated drivers but the effect is
still the same. So there are two filters active for each additional
zcrypt device node: The adapter/domain needs to be enabled on the ap
bus level and it needs to be active on the zcrypt device node level.

ea9e7568f7 crypto: mxs-dcp - Implement sha import/export
The mxs-dcp driver fails to probe if sha1/sha256 are supported:

[    2.455404] mxs-dcp 80028000.dcp: Failed to register sha1 hash!
[    2.464042] mxs-dcp: probe of 80028000.dcp failed with error -22

This happens because since commit 8996eafdcb ("crypto: ahash - ensure
statesize is non-zero") import/export is mandatory and ahash_prepare_alg
fails on statesize == 0.

A set of dummy import/export functions were implemented in commit
9190b6fd5d ("crypto: mxs-dcp - Add empty hash export and import") but
statesize is still zero and the driver fails to probe. That change was
apparently part of some unrelated refactoring.

Fix by actually implementing import/export.

cfa1d74495 crypto: qat - move temp buffers off the stack
Arnd reports that with Kees's latest VLA patches applied, the HMAC
handling in the QAT driver uses a worst case estimate of 160 bytes
for the SHA blocksize, allowing the compiler to determine the size
of the stack frame at compile time and throw a warning:

  drivers/crypto/qat/qat_common/qat_algs.c: In function 'qat_alg_do_precomputes':
  drivers/crypto/qat/qat_common/qat_algs.c:257:1: error: the frame size
  of 1112 bytes is larger than 1024 bytes [-Werror=frame-larger-than=]

Given that this worst case estimate is only 32 bytes larger than the
actual block size of SHA-512, the use of a VLA here was hiding the
excessive size of the stack frame from the compiler, and so we should
try to move these buffers off the stack.

So move the ipad/opad buffers and the various SHA state descriptors
into the tfm context struct. Since qat_alg_do_precomputes() is only
called in the context of a setkey() operation, this should be safe.
Using SHA512_BLOCK_SIZE for the size of the ipad/opad buffers allows
them to be used by SHA-1/SHA-256 as well.

cdf640a69f crypto: s5p-sss: Add aes-ctr support
Add support for aes counter(ctr) block cipher mode of operation for
Exynos Hardware. In contrast to ecb and cbc modes, aes-ctr allows
encyption/decryption for request sizes not being a multiple of 16(bytes).

Hardware requires block sizes being a multiple of 16(bytes). In order to
achieve this, copy request source and destination memory, and align it's size
to 16. That way hardware processes additional bytes, that are omitted
when copying the result back to its original destination.

Tested on Odroid-U3 with Exynos 4412 CPU, kernel 4.19-rc2 with crypto
run-time self test testmgr.

Looking into the code:

  int ret, bar_mask;
    :
  for_each_set_bit(bar_nr, (const unsigned long *)&bar_mask,

It is casting a 32-bit integer pointer to a 64-bit unsigned long
pointer. There are two problems here. First, the 32-bit pointer address
may not be 64-bit aligned. Secondly, it is accessing an extra 4 bytes.

This is fixed by changing the bar_mask type to unsigned long.

d80771c083 crypto: mxs-dcp - Fix wait logic on chan threads
When compiling with CONFIG_DEBUG_ATOMIC_SLEEP=y the mxs-dcp driver
prints warnings such as:

WARNING: CPU: 0 PID: 120 at kernel/sched/core.c:7736 __might_sleep+0x98/0x9c
do not call blocking ops when !TASK_RUNNING; state=1 set at [<8081978c>] dcp_chan_thread_sha+0x3c/0x2ec

The problem is that blocking ops will manipulate current->state
themselves so it is not allowed to call them between
set_current_state(TASK_INTERRUPTIBLE) and schedule().

Fix this by converting the per-chan mutex to a spinlock (it only
protects tiny list ops anyway) and rearranging the wait logic so that
callbacks are called current->state as TASK_RUNNING. Those callbacks
will indeed call blocking ops themselves so this is required.

Add CAAM driver that works using the DPSECI backend, i.e. manages
DPSECI DPAA2 objects sitting on the Management Complex (MC) fsl-mc bus.

Data transfers (crypto requests) are sent/received to/from CAAM crypto
engine via Queue Interface (v2), this being similar to existing caam/qi.
OTOH, configuration/setup (obtaining virtual queue IDs, authorization
etc.) is done by sending commands to the MC f/w.

Note that the CAAM accelerator included in DPAA2 platforms still has
Job Rings. However, the driver being added does not handle access
via this backend. Kconfig & Makefile are updated such that DPAA2-CAAM
(a.k.a. "caam/qi2") driver does not depend on caam/jr or caam/qi
backends - which rely on platform bus support (ctrl.c).

Support for the following aead and authenc algorithms is also added
in this patch:
-aead:
gcm(aes)
rfc4106(gcm(aes))
rfc4543(gcm(aes))
-authenc:
authenc(hmac({md5,sha*}),cbc({aes,des,des3_ede}))
echainiv(authenc(hmac({md5,sha*}),cbc({aes,des,des3_ede})))

13cc6f48c7 crypto: caam/jr - fix ablkcipher_edesc pointer arithmetic
In some cases the zero-length hw_desc array at the end of
ablkcipher_edesc struct requires for 4B of tail padding.

Due to tail padding and the way pointers to S/G table and IV
are computed:
	edesc->sec4_sg = (void *)edesc + sizeof(struct ablkcipher_edesc) +
			 desc_bytes;
	iv = (u8 *)edesc->hw_desc + desc_bytes + sec4_sg_bytes;
first 4 bytes of IV are overwritten by S/G table.

Update computation of pointer to S/G table to rely on offset of hw_desc
member and not on sizeof() operator.

3702a0585e crypto: ccp - add timeout support in the SEV command
Currently, the CCP driver assumes that the SEV command issued to the PSP
will always return (i.e. it will never hang).  But recently, firmware bugs
have shown that a command can hang.  Since of the SEV commands are used
in probe routines, this can cause boot hangs and/or loss of virtualization
capabilities.

To protect against firmware bugs, add a timeout in the SEV command
execution flow.  If a command does not complete within the specified
timeout then return -ETIMEOUT and stop the driver from executing any
further commands since the state of the SEV firmware is unknown.

Earlier used to post the current command without checking queue full
     after backlog submissions. So, post the current command only after
     confirming the space in queue after backlog submissions.

     Maintain host write index instead of reading device registers
     to get the next free slot to post the command.

     Return -ENOSPC in queue full case.

0522236d4f crypto: vmx - Fix sleep-in-atomic bugs
This patch fixes sleep-in-atomic bugs in AES-CBC and AES-XTS VMX
implementations. The problem is that the blkcipher_* functions should
not be called in atomic context.

The bugs can be reproduced via the AF_ALG interface by trying to
encrypt/decrypt sufficiently large buffers (at least 64 KiB) using the
VMX implementations of 'cbc(aes)' or 'xts(aes)'. Such operations then
trigger BUG in crypto_yield():

d5acba26bf Char/Misc driver patches for 4.19-rc1
Here is the bit set of char/misc drivers for 4.19-rc1
 
 There is a lot here, much more than normal, seems like everyone is
 writing new driver subsystems these days...  Anyway, major things here
 are:
 	- new FSI driver subsystem, yet-another-powerpc low-level
 	  hardware bus
 	- gnss, finally an in-kernel GPS subsystem to try to tame all of
 	  the crazy out-of-tree drivers that have been floating around
 	  for years, combined with some really hacky userspace
 	  implementations.  This is only for GNSS receivers, but you
 	  have to start somewhere, and this is great to see.
 Other than that, there are new slimbus drivers, new coresight drivers,
 new fpga drivers, and loads of DT bindings for all of these and existing
 drivers.
 
 Full details of everything is in the shortlog.
 
 All of these have been in linux-next for a while with no reported
 issues.

5e2d059b52 powerpc updates for 4.19
Notable changes:
 
  - A fix for a bug in our page table fragment allocator, where a page table page
    could be freed and reallocated for something else while still in use, leading
    to memory corruption etc. The fix reuses pt_mm in struct page (x86 only) for
    a powerpc only refcount.
 
  - Fixes to our pkey support. Several are user-visible changes, but bring us in
    to line with x86 behaviour and/or fix outright bugs. Thanks to Florian Weimer
    for reporting many of these.
 
  - A series to improve the hvc driver & related OPAL console code, which have
    been seen to cause hardlockups at times. The hvc driver changes in particular
    have been in linux-next for ~month.
 
  - Increase our MAX_PHYSMEM_BITS to 128TB when SPARSEMEM_VMEMMAP=y.
 
  - Remove Power8 DD1 and Power9 DD1 support, neither chip should be in use
    anywhere other than as a paper weight.
 
  - An optimised memcmp implementation using Power7-or-later VMX instructions
 
  - Support for barrier_nospec on some NXP CPUs.
 
  - Support for flushing the count cache on context switch on some IBM CPUs
    (controlled by firmware), as a Spectre v2 mitigation.
 
  - A series to enhance the information we print on unhandled signals to bring it
    into line with other arches, including showing the offending VMA and dumping
    the instructions around the fault.

656ecc16e8 crypto/nx: Initialize 842 high and normal RxFIFO control registers
NX increments readOffset by FIFO size in receive FIFO control register
when CRB is read. But the index in RxFIFO has to match with the
corresponding entry in FIFO maintained by VAS in kernel. Otherwise NX
may be processing incorrect CRBs and can cause CRB timeout.

VAS FIFO offset is 0 when the receive window is opened during
initialization. When the module is reloaded or in kexec boot, readOffset
in FIFO control register may not match with VAS entry. This patch adds
nx_coproc_init OPAL call to reset readOffset and queued entries in FIFO
control register for both high and normal FIFOs.

afb31cd2d1 crypto: ccp - Check for NULL PSP pointer at module unload
Should the PSP initialization fail, the PSP data structure will be
freed and the value contained in the sp_device struct set to NULL.
At module unload, psp_dev_destroy() does not check if the pointer
value is NULL and will end up dereferencing a NULL pointer.

Add a pointer check of the psp_data field in the sp_device struct
in psp_dev_destroy() and return immediately if it is NULL.

f53ad3e1b3 crypto: ccree - allow bigger than sector XTS op
The ccree driver had a sanity check that we are not asked
to encrypt an XTS buffer bigger than a sane sector size
since XTS IV needs to include the sector number in the IV
so this is not expected in any real use case.

Unfortunately, this breaks cryptsetup benchmark test which
has a synthetic performance test using 64k buffer of data
with the same IV.

Remove the sanity check and allow the user to hang themselves
and/or run benchmarks if they so wish.

This accelerator is found inside hisilicon hip06 and hip07 SoCs.
Each instance provides a number of queues which feed a different number of

The queues are operating in an out of order mode in the interests of
throughput. The silicon does not do tracking of dependencies between
multiple 'messages' or update of the IVs as appropriate for training.

c89105c9b3 staging: fsl-mc: Move DPIO from staging to drivers/soc/fsl
Move the NXP DPIO (Datapath I/O Driver) out of the
drivers/staging directory and into the drivers/soc/fsl directory.

The DPIO driver enables access to Queue and Buffer Manager (QBMAN)
hardware on NXP DPAA2 devices. This is a prerequisite to moving the
DPAA2 Ethernet driver out of staging.

46d8c4b286 crypto: padlock-aes - Fix Nano workaround data corruption
This was detected by the self-test thanks to Ard's chunking patch.

I finally got around to testing this out on my ancient Via box.  It
turns out that the workaround got the assembly wrong and we end up
doing count + initial cycles of the loop instead of just count.

This obviously causes corruption, either by overwriting the source
that is yet to be processed, or writing over the end of the buffer.

On CPUs that don't require the workaround only ECB is affected.
On Nano CPUs both ECB and CBC are affected.

This patch fixes it by doing the subtraction prior to the assembly.

cca9bab1b7 tcp: use monotonic timestamps for PAWS
Using get_seconds() for timestamps is deprecated since it can lead
to overflows on 32-bit systems. While the interface generally doesn't
overflow until year 2106, the specific implementation of the TCP PAWS
algorithm breaks in 2038 when the intermediate signed 32-bit timestamps
overflow.

A related problem is that the local timestamps in CLOCK_REALTIME form
lead to unexpected behavior when settimeofday is called to set the system
clock backwards or forwards by more than 24 days.

While the first problem could be solved by using an overflow-safe method
of comparing the timestamps, a nicer solution is to use a monotonic
clocksource with ktime_get_seconds() that simply doesn't overflow (at
least not until 136 years after boot) and that doesn't change during
settimeofday().

To make 32-bit and 64-bit architectures behave the same way here, and
also save a few bytes in the tcp_options_received structure, I'm changing
the type to a 32-bit integer, which is now safe on all architectures.

Finally, the ts_recent_stamp field also (confusingly) gets used to store
a jiffies value in tcp_synq_overflow()/tcp_synq_no_recent_overflow().
This is currently safe, but changing the type to 32-bit requires
some small changes there to keep it working.

which only reverses the last two blocks if the stolen ciphertext amount
are none zero. Move it to the kernel chosen format of CBC-CS3  which swaps
the final blocks unconditionally and rename it to "cts" now that it
complies with the kernel format and passes the self tests.

Ironically, the CryptoCell REE HW does just that, so the fix is dropping
the code that forced it to use plain CBC if the ciphertext was block

9744fec95f crypto: inside-secure - remove request list to improve performance
This patch main goal is to improve driver performance by moving the
crypto request from a list to a RDR ring shadow.

This is possible since there is one producer and one consume for this
RDR request shadow and one ring descriptor is left unused.
Doing this change eliminates the use of spinlock when accessing the
descriptor ring and the need to dynamicaly allocate memory per crypto
request.

The crypto request is placed in the first RDR shadow descriptor only
if there are enough descriptors, when the result handler is invoked,
it fetches the first result descriptor from RDR shadow.

ac3167257b headers: separate linux/mod_devicetable.h from linux/platform_device.h
At over 4000 #includes, <linux/platform_device.h> is the 9th most
#included header file in the Linux kernel.  It does not need
<linux/mod_devicetable.h>, so drop that header and explicitly add
<linux/mod_devicetable.h> to source files that need it.

   4146 #include <linux/platform_device.h>

After this patch, there are 225 files that use <linux/mod_devicetable.h>,
for a reduction of around 3900 times that <linux/mod_devicetable.h>
does not have to be read & parsed.

    225 #include <linux/mod_devicetable.h>

This patch was build-tested on 20 different arch-es.

It also makes these drivers SubmitChecklist#1 compliant.

a86854d0c5 treewide: devm_kzalloc() -> devm_kcalloc()
The devm_kzalloc() function has a 2-factor argument form, devm_kcalloc().
This patch replaces cases of:

        devm_kzalloc(handle, a * b, gfp)

with:
        devm_kcalloc(handle, a * b, gfp)

as well as handling cases of:

        devm_kzalloc(handle, a * b * c, gfp)

with:

        devm_kzalloc(handle, array3_size(a, b, c), gfp)

as it's slightly less ugly than:

        devm_kcalloc(handle, array_size(a, b), c, gfp)

This does, however, attempt to ignore constant size factors like:

        devm_kzalloc(handle, 4 * 1024, gfp)

though any constants defined via macros get caught up in the conversion.

Any factors with a sizeof() of "unsigned char", "char", and "u8" were
dropped, since they're redundant.

Some manual whitespace fixes were needed in this patch, as Coccinelle
really liked to write "=devm_kcalloc..." instead of "= devm_kcalloc...".

The Coccinelle script used for this was:

6396bb2215 treewide: kzalloc() -> kcalloc()
The kzalloc() function has a 2-factor argument form, kcalloc(). This
patch replaces cases of:

        kzalloc(a * b, gfp)

with:
        kcalloc(a * b, gfp)

as well as handling cases of:

        kzalloc(a * b * c, gfp)

with:

        kzalloc(array3_size(a, b, c), gfp)

as it's slightly less ugly than:

        kzalloc_array(array_size(a, b), c, gfp)

This does, however, attempt to ignore constant size factors like:

        kzalloc(4 * 1024, gfp)

though any constants defined via macros get caught up in the conversion.

Any factors with a sizeof() of "unsigned char", "char", and "u8" were
dropped, since they're redundant.

The Coccinelle script used for this was:

// Fix redundant parens around sizeof().

c2e415fe75 crypto: clarify licensing of OpenSSL asm code
Several source files have been taken from OpenSSL. In some of them a
comment that "permission to use under GPL terms is granted" was
included below a contradictory license statement. In several cases,
there was no indication that the license of the code was compatible
with the GPLv2.

This change clarifies the licensing for all of these files. I've
confirmed with the author (Andy Polyakov) that a) he has licensed the
files with the GPLv2 comment under that license and b) that he's also
happy to license the other files under GPLv2 too. In one case, the
file is already contained in his CRYPTOGAMS bundle, which has a GPLv2
option, and so no special measures are needed.

In all cases, the license status of code has been clarified by making
the GPLv2 license prominent.

The .S files have been regenerated from the updated .pl files.

This is a comment-only change. No code is changed.

f16b613ca8 crypto: chtls - fix a missing-check bug
In do_chtls_setsockopt(), the tls crypto info is first copied from the
poiner 'optval' in userspace and saved to 'tmp_crypto_info'. Then the
'version' of the crypto info is checked. If the version is not as expected,
i.e., TLS_1_2_VERSION, error code -ENOTSUPP is returned to indicate that
the provided crypto info is not supported yet. Then, the 'cipher_type'
field of the 'tmp_crypto_info' is also checked to see if it is
TLS_CIPHER_AES_GCM_128. If it is, the whole struct of
tls12_crypto_info_aes_gcm_128 is copied from the pointer 'optval' and then
the function chtls_setkey() is invoked to set the key.

Given that the 'optval' pointer resides in userspace, a malicious userspace
process can race to change the data pointed by 'optval' between the two
copies. For example, a user can provide a crypto info with TLS_1_2_VERSION
and TLS_CIPHER_AES_GCM_128. After the first copy, the user can modify the
'version' and the 'cipher_type' fields to any versions and/or cipher types
that are not allowed. This way, the user can bypass the checks, inject
bad data to the kernel, cause chtls_setkey() to set a wrong key or other
issues.

This patch reuses the data copied in the first try so as to ensure these
checks will not be bypassed.

Enable CryptoCell support for hardware keys.

Hardware keys are regular AES keys loaded into CryptoCell internal memory
via firmware, often from secure boot ROM or hardware fuses at boot time.

As such, they can be used for enc/dec purposes like any other key but
cannot (read: extremely hard to) be extracted since since they are not
available anywhere in RAM during runtime.

The mechanism has some similarities to s390 secure keys although the keys
are not wrapped or sealed, but simply loaded offline. The interface was
therefore modeled based on the s390 secure keys support.

584201f189 crypto: crypto4xx - extend aead fallback checks
1020 bytes is the limit for associated data. Any more
and it will no longer fit into hash_crypto_offset anymore.

The hardware will not process aead requests with plaintext
that have less than AES_BLOCK_SIZE bytes. When decrypting
aead requests the authsize has to be taken in account as
well, as it is part of the cryptlen. Otherwise the hardware
will think it has been misconfigured and will return:

aead return err status = 0x98

For rtc4543(gcm(aes)), the hardware has a dedicated GMAC
mode as part of the hash function set.

Fix this issue for the AMCC Crypto4xx hardware engine.
The tcrypt test case for cts(cbc(aes)) is now correctly passed.

The hardware uses only the last 32-bits as the counter while the
kernel tests (aes_ctr_enc_tv_template[4] for example) expect that
the whole IV is a counter. To make this work, the driver will
fallback if the counter is going to overlow.

The aead's crypto4xx_setup_fallback() function is renamed to
crypto4xx_aead_setup_fallback.

37ff02acaa crypto: cavium - Fix fallout from CONFIG_VMAP_STACK
Enabling virtual mapped kernel stacks breaks the thunderx_zip
driver. On compression or decompression the executing CPU hangs
in an endless loop. The reason for this is the usage of __pa
by the driver which does no longer work for an address that is
not part of the 1:1 mapping.

The zip driver allocates a result struct on the stack and needs
to tell the hardware the physical address within this struct
that is used to signal the completion of the request.

As the hardware gets the wrong address after the broken __pa
conversion it writes to an arbitrary address. The zip driver then
waits forever for the completion byte to contain a non-zero value.

Allocating the result struct from 1:1 mapped memory resolves this
bug.

3a488aaec6 crypto: caam/qi - fix IV DMA mapping and updating
There are two IV-related issues:
(1) crypto API does not guarantee to provide an IV buffer that is DMAable,
thus it's incorrect to DMA map it
(2) for in-place decryption, since ciphertext is overwritten with
plaintext, updated IV (req->info) will contain the last block of plaintext
(instead of the last block of ciphertext)

While these two issues could be fixed separately, it's straightforward
to fix both in the same time - by using the {ablkcipher,aead}_edesc
extended descriptor to store the IV that will be fed to the crypto engine;
this allows for fixing (2) by saving req->src[last_block] in req->info
directly, i.e. without allocating yet another temporary buffer.

A side effect of the fix is that it's no longer possible to have the IV
contiguous with req->src or req->dst.
Code checking for this case is removed.

This patches uses the state size of the algorithms instead of their
digest size to copy the ipad and opad in the context. This doesn't fix
anything as the state and digest size are the same for many algorithms,
and for all the hmac currently supported by this driver. However
hmac(sha224) use the sha224 hash function which has a different digest
and state size. This commit prepares the addition of such algorithms.

15f64ee0ae crypto: inside-secure - improve the skcipher token
The token used for encryption and decryption of skcipher algorithms sets
its stat field to "last packet". As it's a cipher only algorithm, there
is not hash operation and thus the "last hash" bit should be set to tell
the internal engine no hash operation should be performed.

This does not fix a bug, but improves the token definition to follow
exactly what's advised by the datasheet.

This patches moves the digest information from the transformation

of time, as the HMAC init functions call the SHA init one which reset
the value. This lead to a small percentage of HMAC being incorrectly
computed under heavy load.

e9acf05255 crypto: cavium - Replace mdelay with msleep in cpt_device_init
cpt_device_init() is never called in atomic context.

The call chain ending up at cpt_device_init() is:
[1] cpt_device_init() <- cpt_probe()
cpt_probe() is only set as ".probe" in pci_driver structure
"cpt_pci_driver".

Despite never getting called from atomic context, cpt_device_init() calls
mdelay(100), i.e. busy wait for 100ms.
That is not necessary and can be replaced with msleep to
avoid busy waiting.

This is found by a static analysis tool named DCNS written by myself.
