16287397ec crypto: qcom-rng - fix infinite loop on requests not multiple of WORD_SZ
The commit referenced in the Fixes tag removed the 'break' from the else
branch in qcom_rng_read(), causing an infinite loop whenever 'max' is
not a multiple of WORD_SZ. This can be reproduced e.g. by running:

    kcapi-rng -b 67 >/dev/null

There are many ways to fix this without adding back the 'break', but
they all seem more awkward than simply adding it back, so do just that.

Tested on a machine with Qualcomm Amberwing processor.

I notieced the log is not properly aligned:

  PERL drivers/crypto/vmx/ghashp8-ppc.S
  CC [M]  drivers/crypto/vmx/aes.o

Add some spaces after 'PERL'.

While I was here, I cleaned up the Makefile:

 - Merge the two similar rules

 - Remove redundant 'clean-files' (Having 'targets' is enough)

 - Move the flavour into the build command

This still avoids the build failures fixed by commit 4ee812f614

5718218231 crypto: atmel-sha204a - Suppress duplicate error message
Returning an error value in an i2c remove callback results in an error
message being emitted by the i2c core, but otherwise it doesn't make a
difference. The device goes away anyhow and the devm cleanups are
called.

As atmel_sha204a_remove already emits an error message ant the additional
error message by the i2c core doesn't add any useful information, change
the return value to zero to suppress this error message.

Note that after atmel_sha204a_remove() returns *i2c_priv is freed, so there
is trouble ahead because atmel_sha204a_rng_done() might be called after
that freeing. So make the error message a bit more frightening.

ATSHA204 is predecessor of ATSHA204A which supports less features and some
of them are slightly different.

Introduce a new compatible string for ATSHA204 cryptochip "atmel,atsha204".

Current version of Linux kernel driver atmel-sha204a.c implements only hw
random number generator which is same in both ATSHA204 and ATSHA204A
cryptochips. So driver already supports also ATSHA204 hw generator, so just
simply extends list of compatible strings.

Since commit 358ba762d9 ("crypto: caam - enable prediction resistance

caam_jr 2101000.jr: 20003c5b: CCB: desc idx 60: RNG: Hardware error
hwrng: no data available

This error is due to an incorrect entropy delay for i.MX6SX.

Fix it by increasing the minimum entropy delay for i.MX6SX
as done in U-Boot:
https://patchwork.ozlabs.org/project/uboot/patch/20220415111049.2565744-1-gaurav.jain@nxp.com/

As explained in the U-Boot patch:

"RNG self tests are run to determine the correct entropy delay.
Such tests are executed with different voltages and temperatures to identify
the worst case value for the entropy delay. For i.MX6SX, it was determined
that after adding a margin value of 1000 the minimum entropy delay should be
at least 12000."

1. In user namespaces, normal user tasks (e.g. VMM) can change their

   init_ex_path is provided as a module param related to root file
   system. Solution: use the root directory of init_task to avoid
   accessing the wrong file.

2. Normal user tasks (e.g. VMM) don't have the privilege to access
   the INIT_EX data file. Solution: open the file as root and
   restore permissions immediately.

c690c7f631 crypto: qat - rework the VF2PF interrupt handling logic
Change the VF2PF interrupt handler in the PF ISR and the definition of
the internal PFVF API to correct the current implementation, which can
result in missed interrupts.

More specifically, current HW generations consider a write to the mask
register, regardless of the value, as an acknowledge of any pending
VF2PF interrupt. Therefore, if there is an interrupt between the source
register read and the mask register write, such interrupt will not be
delivered and silently acknowledged, resulting in a lost VF2PF message.

To work around the problem, rather than disabling specific interrupts,
disable all the interrupts and re-enable only the ones that we are not
serving (excluding the already disabled ones too). This will force any
other pending interrupt to be triggered and be serviced by a subsequent
ISR.

This new approach requires, however, changes to the interrupt related
pfvf_ops functions. In particular, get_vf2pf_sources() has now been
removed in favor of disable_pending_vf2pf_interrupts(), which not only
retrieves and returns the pending (and enabled) sources, but also
disables them.
As a consequence, introduce the adf_disable_pending_vf2pf_interrupts()
utility in place of adf_disable_vf2pf_interrupts_irq(), which is no
longer needed.

9ff9139b5d crypto: qat - fix ETR sources enabled by default on GEN2 devices
When the driver starts the device, it enables all the necessary
interrupts. However interrupts associated to host rings are enabled by
default on all GEN2 devices (except for dh895x) even when SR-IOV is
active. Fix this behaviour by checking if data structures associated to
VFs have been allocated to determine whether to enable such interrupts
or not.

Since the logic for the fix is the same across GEN2 devices, replace
the function to be fixed (adf_enable_ints()) with a single one
(adf_gen2_enable_ints()) in the common GEN2 code in adf_gen2_hw_data.c.
Likewise, remove the unnecessary duplication of defines too.

When list_for_each_entry() completes the iteration over the whole list
without breaking the loop, the iterator value will be a bogus pointer
computed based on the head element.

While it is safe to use the pointer to determine if it was computed
based on the head element, either with list_entry_is_head() or
&pos->member == head, using the iterator variable after the loop should
be avoided.

In preparation to limit the scope of a list iterator to the list
traversal loop, use a dedicated pointer to point to the found element [1].

  - Support is added for i.MXRT10xx, a Cortex-M7 based microcontroller
    from NXP. At the moment this is still incomplete as other portions
    are merged through different trees.
 
  - Long abandoned support for running NOMMU ARMv4 or ARMv5 platforms
    gets removed, now the Arm NOMMU platforms are limited to the
    Cortex-M family of microcontrollers
 
  - Two old PXA boards get removed, along with corresponding driver
    bits.
 
  - Continued cleanup of the Intel IXP4xx platforms, removing some
    remnants of the old board files.
 
  - Minor Cleanups and fixes for Orion, PXA, MMP, Mstar, Samsung
 
  - CPU idle support for AT91

a680b1832c crypto: qcom-rng - ensure buffer for generate is completely filled
The generate function in struct rng_alg expects that the destination
buffer is completely filled if the function returns 0. qcom_rng_read()
can run into a situation where the buffer is partially filled with
randomness and the remaining part of the buffer is zeroed since
qcom_rng_generate() doesn't check the return value. This issue can
be reproduced by running the following from libkcapi:

    kcapi-rng -b 9000000 > OUTFILE

The generated OUTFILE will have three huge sections that contain all
zeros, and this is caused by the code where the test
'val & PRNG_STATUS_DATA_AVAIL' fails.

Let's fix this issue by ensuring that qcom_rng_read() always returns
with a full buffer if the function returns success. Let's also have
qcom_rng_generate() return the correct value.

Here's some statistics from the ent project
(https://www.fourmilab.ch/random/) that shows information about the
quality of the generated numbers:

    $ ent -c qcom-random-before
    Value Char Occurrences Fraction
      0           606748   0.067416
      1            33104   0.003678

    255   �        33239   0.003693

    Total:       9000000   1.000000

    Entropy = 7.811590 bits per byte.

    Optimum compression would reduce the size
    of this 9000000 byte file by 2 percent.

    Chi square distribution for 9000000 samples is 9329962.81, and
    randomly would exceed this value less than 0.01 percent of the
    times.

    Arithmetic mean value of data bytes is 119.3731 (127.5 = random).
    Monte Carlo value for Pi is 3.197293333 (error 1.77 percent).
    Serial correlation coefficient is 0.159130 (totally uncorrelated =
    0.0).

Without this patch, the results of the chi-square test is 0.01%, and
the numbers are certainly not random according to ent's project page.
The results improve with this patch:

    $ ent -c qcom-random-after
    Value Char Occurrences Fraction

    Total:       9000000   1.000000

    Entropy = 7.999979 bits per byte.

    Optimum compression would reduce the size
    of this 9000000 byte file by 0 percent.

    Chi square distribution for 9000000 samples is 258.77, and randomly
    would exceed this value 42.24 percent of the times.

    Arithmetic mean value of data bytes is 127.5006 (127.5 = random).
    Monte Carlo value for Pi is 3.141277333 (error 0.01 percent).
    Serial correlation coefficient is 0.000468 (totally uncorrelated =

8893d27ffc crypto: qat - disable registration of algorithms
The implementations of aead and skcipher in the QAT driver do not
support properly requests with the CRYPTO_TFM_REQ_MAY_BACKLOG flag set.
If the HW queue is full, the driver returns -EBUSY but does not enqueue
the request.
This can result in applications like dm-crypt waiting indefinitely for a
completion of a request that was never submitted to the hardware.

To avoid this problem, disable the registration of all crypto algorithms
in the QAT driver by setting the number of crypto instances to 0 at
configuration time.

The zynqmp-sha driver is always loaded and register its algorithm even on
platform which do not have the proper hardware.
This lead to a stacktrace due to zynqmp-sha3-384 failing its crypto
self tests.
So check if hardware is present via the firmware API call get_version.

While at it, simplify the platform_driver by using module_platform_driver()

Furthermore the driver should depend on ZYNQMP_FIRMWARE since it cannot

Xilinx ZynqMP SoC has SHA3 engine used for secure hash calculation.
The flow is
SHA3 request from Userspace -> SHA3 driver-> ZynqMp driver-> Firmware ->
SHA3 HW Engine

SHA3 HW engine in Xilinx ZynqMP SoC, does not support parallel processing
of 2 hash requests.
Therefore, software fallback is being used for init, update, final,
export and import in the ZynqMP SHA driver
For digest, the calculation of SHA3 hash is done by the hardened
SHA3 accelerator in Xilinx ZynqMP SoC.

Kernel code should always use “flexible array members”[1] for these
cases. The older style of one-element or zero-length arrays should
no longer be used[2].

This code was transformed with the help of Coccinelle:

e236ab0d43 crypto: octeontx2 - increase CPT HW instruction queue length
LDWB is getting incorrectly used in HW when
CPT_AF_LF()_PTR_CTL[IQB_LDWB]=1 and CPT instruction queue has less than
320 free entries. So, increase HW instruction queue size by 320 and give
320 entries less for SW/NIX RX as a SW workaround.

9eef6e972a crypto: octeontx2 - disable DMA black hole on an DMA fault
When CPT_AF_DIAG[FLT_DIS] = 0 and a CPT engine access to
LLC/DRAM encounters a fault/poison, a rare case may result
in unpredictable data being delivered to a CPT engine.
So, this patch adds code to set FLT_DIS as a workaround.

bd9305b0cb crypto: octeontx2 - CN10K CPT to RNM workaround
When software sets CPT_AF_CTL[RNM_REQ_EN]=1 and RNM in not producing
entropy(i.e., RNM_ENTROPY_STATUS[NORMAL_CNT] < 0x40), the first cycle of
the response may be lost due to a conditional clocking issue. Due to
this, the subsequent random number stream will be corrupted. So, this
patch adds support to ensure RNM_ENTROPY_STATUS[NORMAL_CNT] = 0x40
before writing CPT_AF_CTL[RNM_REQ_EN] = 1, as a workaround.

This is justified because the mask size (eng_grps->engs_num) can be at
most 144 (OTX2_CPT_MAX_ENGINES bits), which is larger than available
storage. 4 * 32 == 128, so this must be 5: 5 * 32bit = 160.

Additionally clear the mask before conversion so trailing bits are zero.

642a7d49c2 crypto: qat - fix access to PFVF interrupt registers for GEN4
The logic that detects, enables and disables pfvf interrupts was
expecting a single CSR per VF. Instead, the source and mask register are
two registers with a bit per VF.
Due to this, the driver is reading and setting reserved CSRs and not
masking the correct source of interrupts.

Fix the access to the source and mask register for QAT GEN4 devices by
removing the outer loop in adf_gen4_get_vf2pf_sources(),
adf_gen4_enable_vf2pf_interrupts() and
adf_gen4_disable_vf2pf_interrupts() and changing the helper macros
ADF_4XXX_VM2PF_SOU and ADF_4XXX_VM2PF_MSK.

that a ring reset failed even if the operation was successful.

Fix by starting the definition of ring reset result values from 0.

c5d692a233 crypto: hisilicon - cleanup warning in qm_get_qos_value()
Building with clang static analysis returns this warning:

qm.c:4382:11: warning: The left operand of '==' is a garbage value
        if (*val == 0 || *val > QM_QOS_MAX_VAL || ret) {
            ~~~~ ^

The call to qm_qos_value_init() can return an error without setting
*val.  So check ret before checking *val.

29009604ad crypto: stm32/crc32 - Fix kernel BUG triggered in probe()
The include/linux/crypto.h struct crypto_alg field cra_driver_name description
states "Unique name of the transformation provider. " ... " this contains the
name of the chip or provider and the name of the transformation algorithm."

In case of the stm32-crc driver, field cra_driver_name is identical for all
registered transformation providers and set to the name of the driver itself,
which is incorrect. This patch fixes it by assigning a unique cra_driver_name
to each registered transformation provider.

The kernel crash is triggered when the driver calls crypto_register_shashes()
which calls crypto_register_shash(), which calls crypto_register_alg(), which
calls __crypto_register_alg(), which returns -EEXIST, which is propagated
back through this call chain. Upon -EEXIST from crypto_register_shash(), the
crypto_register_shashes() starts unregistering the providers back, and calls
crypto_unregister_shash(), which calls crypto_unregister_alg(), and this is
where the BUG() triggers due to incorrect cra_refcnt.

d7779e22e8 crypto: ux500 - Use platform_get_irq() to get the interrupt
platform_get_resource(pdev, IORESOURCE_IRQ, ..) relies on static
allocation of IRQ resources in DT core code, this causes an issue
when using hierarchical interrupt domains using "interrupts" property
in the node as this bypasses the hierarchical setup and messes up the
irq chaining.

In preparation for removal of static setup of IRQ resource from DT core
code use platform_get_irq() so that interrupt mapping is created on demand.

While at it also store the IRQ number in struct cryp_device_data so that
we don't have to call platform_get_irq() frequently.
