crypto: akcipher - default implementation for setting a private key

Changes from v1:
  * removed the default implementation from set_pub_key: it is assumed that
    an implementation must always have this callback defined as there are
    no use case for an algorithm, which doesn't need a public key

Many akcipher implementations (like ECDSA) support only signature
verifications, so they don't have all callbacks defined.

Commit 78a0324f4a53 ("crypto: akcipher - default implementations for
request callbacks") introduced default callbacks for sign/verify
operations, which just return an error code.

However, these are not enough, because before calling sign the caller would
likely call set_priv_key first on the instantiated transform (as the
in-kernel testmgr does). This function does not have a default stub, so the
kernel crashes, when trying to set a private key on an akcipher, which
doesn't support signature generation.

I've noticed this, when trying to add a KAT vector for ECDSA signature to
the testmgr.

With this patch the testmgr returns an error in dmesg (as it should)
instead of crashing the kernel NULL ptr dereference.

crypto: ccp - Fail the PSP initialization when writing psp data file failed

Currently the OS continues the PSP initialization when there is a write

SEV is properly INIT'd even though the psp data file is not updated.

crypto: ccp - Initialize PSP when reading psp data file failed

Currently the OS fails the PSP initialization when the file specified at
'init_ex_path' does not exist or has invalid content. However the SEV
spec just requires users to allocate 32KB of 0xFF in the file, which can
be taken care of by the OS easily.

To improve the robustness during the PSP init, leverage the retry
mechanism and continue the init process:

Before the first INIT_EX call, if the content is invalid or missing,
continue the process by feeding those contents into PSP instead of
aborting. PSP will then override it with 32KB 0xFF and return
SEV_RET_SECURE_DATA_INVALID status code. In the second INIT_EX call,
this 32KB 0xFF content will then be fed and PSP will write the valid
data to the file.

In order to do this, sev_read_init_ex_file should only be called once
for the first INIT_EX call. Calling it again for the second INIT_EX call
will cause the invalid file content overwriting the valid 32KB 0xFF data
provided by PSP in the first INIT_EX call.

arc4 is named ecb(arc4), not arc4.

Tests are sparsely numbered from 0 to 1000. For example:
    modprobe tcrypt mode=12
tests sha512, and
    modprobe tcrypt mode=152
tests rfc4543(gcm(aes))) - AES-GCM as GMAC

The test manager generates WARNING crashdumps every time it attempts
a test using an algorithm that is not available (not built-in to the
kernel or available as a module):

If the kernel is compiled with CRYPTO_USER_API_ENABLE_OBSOLETE
disabled (the default), then these algorithms are not compiled into
the kernel or made into modules and trigger WARNINGs:
    arc4 tea xtea khazad anubis xeta seed

Additionally, any other algorithms that are not enabled in .config
will generate WARNINGs. In RHEL 9.0, for example, the default
selection of algorithms leads to 16 WARNING dumps.

One attempt to fix this was by modifying tcrypt_test() to check
crypto_has_alg() and immediately return 0 if crypto_has_alg() fails,
rather than proceed and return a non-zero error value that causes
the caller (alg_test() in crypto/testmgr.c) to invoke WARN().
That knocks out too many algorithms, though; some combinations
like ctr(des3_ede) would work.

Instead, change the condition on the WARN to ignore a return
value is ENOENT, which is the value returned when the algorithm
or combination of algorithms doesn't exist. Add a pr_warn to
communicate that information in case the WARN is skipped.

This approach allows algorithm tests to work that are combinations,
not provided by one driver, like ctr(blowfish).

Result - no more WARNINGs:

COMPILE_TEST as an alternative is no longer needed.

It is actually better to always build such drivers with OF enabled,
so that the test builds are closer to how each driver will actually be
built on its intended target. Building them without OF may not test
much as the compiler will optimize out potentially large parts of the
code. In the worst case, this could even pop false positive warnings.
Dropping COMPILE_TEST here improves the quality of our testing and
avoids wasting time on non-existent issues.

hwrng: core - let sleep be interrupted when unregistering hwrng

There are two deadlock scenarios that need addressing, which cause
problems when the computer goes to sleep, the interface is set down, and
hwrng_unregister() is called. When the deadlock is hit, sleep is delayed
for tens of seconds, causing it to fail. These scenarios are:

1) The hwrng kthread can't be stopped while it's sleeping, because it
   uses msleep_interruptible() which does not react to kthread_stop.

2) A normal user thread can't be interrupted by hwrng_unregister() while
   it's sleeping, because hwrng_unregister() is called from elsewhere.

We solve both issues by add a completion object called dying that
fulfils waiters once we have started the process in hwrng_unregister.

At the same time, we should cleanup a common and useless dmesg splat
in the same area.

crypto: lib - move __crypto_xor into utils

CRYPTO_LIB_CHACHA depends on CRYPTO for __crypto_xor, defined in
crypto/algapi.c.  This is a layering violation because the dependencies
should only go in the other direction (crypto/ => lib/crypto/).  Also
the correct dependency would be CRYPTO_ALGAPI, not CRYPTO.  Fix this by
moving __crypto_xor into the utils module in lib/crypto/.

Note that CRYPTO_LIB_CHACHA_GENERIC selected XOR_BLOCKS, which is
unrelated and unnecessary.  It was perhaps thought that XOR_BLOCKS was
needed for __crypto_xor, but that's not the case.

crypto: qat - add check to validate firmware images

The function qat_uclo_check_image() validates the MMP and AE firmware
images. If the QAT device supports firmware authentication (indicated
by the handle to firmware loader), the input signed binary MMP and AE
images are validated by parsing the following information:
- Header length
- Full size of the binary
- Type of binary image (MMP or AE Firmware)

Firmware binaries use RSA3K for signing and verification.
The header length for the RSA3k is 0x384 bytes.

All the size field values in the binary are quantified
as DWORDS (1 DWORD = 4bytes).

On an invalid value the function prints an error message and returns
with an error code "EINVAL".
