Alternative fix for CVE-2022-4304
This is about a timing leak in the topmost limb
of the internal result of RSA_private_decrypt,
before the padding check.
There are in fact at least three bugs together that
caused the timing leak:
First and probably most important is the fact that
the blinding did not use the constant time code path
at all when the RSA object was used for a private
decrypt, due to the fact that the Montgomery context
rsa->_method_mod_n was not set up early enough in
rsa_ossl_private_decrypt, when BN_BLINDING_create_param
needed it, and that was persisted as blinding->m_ctx,
although the RSA object creates the Montgomery context
just a bit later.
Then the infamous bn_correct_top was used on the
secret value right after the blinding was removed.
And finally the function BN_bn2binpad did not use
the constant-time code path since the BN_FLG_CONSTTIME
was not set on the secret value.
In order to address the first problem, this patch
makes sure that the rsa->_method_mod_n is initialized
right before the blinding context.
And to fix the second problem, we add a new utility
function bn_correct_top_consttime, a const-time
variant of bn_correct_top.
Together with the fact, that BN_bn2binpad is already
constant time if the flag BN_FLG_CONSTTIME is set,
this should eliminate the timing oracle completely.
In addition the no-asm variant may also have
branches that depend on secret values, because the last
invocation of bn_sub_words in bn_from_montgomery_word
had branches when the function is compiled by certain
gcc compiler versions, due to the clumsy coding style.
So additionally this patch stream-lined the no-asm
C-code in order to avoid branches where possible and
improve the resulting code quality.

Function EVP_PKEY_get_bn_param() uses temporary buffer (on stack or
heap allocated) to store serialized bignum, but after deserializing it
into BIGNUM*, the buffer is not erased and may contain sensitive data.
This change makes sure the buffer is erased if it was successfully
filled before. Unfortunately, it does not distinguish between public and
private key components, and will always erase the buffer.

Calling OPENSSL_init_crypto from inside a RUN_ONCE seems like a bad idea.

The initialisation in OPENSSL_init_crypto is already "run once" protected.

DSA_sign() assumes that the signature passed in is related to DSA_size().
If q is negative then DSA_size() actually fails and returns 0.
A test that tries to allocate the signature buffer using DSA_size() and then
pass it to DSA_sign() will then either.
(1) Have a signature buffer of NULL. In this case it was leaking data
returned via i2d_DSA_SIG.
(2) Cause a seg fault because we created a buffer that was not large

Per the Github conversation with levitte and t8m for pull request #19964, the following issues are not addressed by this patch:
The macro OSSL_CORE_MAKE_FUNC in core_dispatch.h generates a function, and a corresponding function signature typedef with name ending in "_fn". The typedefed signature is unrelated to the signature of the function.
However, provider-decoder.pod describes typedefed signatures generated by the macro, but uses the names of the functions (lacking "_fn") instead of the typedefed signatures, which is a mismatch.
Also, the documented claim about OSSL_FUNC_decoder_export_object, etc that "None of these are actual functions" is contradicted by the fact that the code actually calls those functions, and calls them specifically by those names. E.g. in decoder_meth.c:
decoder->export_object = OSSL_FUNC_decoder_export_object(fns);
The functions are generated by OSSL_CORE_MAKE_FUNC.
The paragraph "None of these are actual functions"... should be replaced by something more like "These function signatures, generated by the OSSL_CORE_MAKE_FUNC macro, are for functions that are offered via function pointers in OSSL_DISPATCH arrays."

fips: Use salt >= 16 bytes in PBKDF2 selftest
NIST SP 800-132 [1] section 5.1 says "[t]he length of the
randomly-generated portion of the salt shall be at least
128 bits", which implies that the salt for PBKDF2 must be at least 16
bytes long (see also Appendix A.2.1).
The FIPS 140-3 IG [2] section 10.3.A requires that "the lengths and the
properties of the Password and Salt parameters, as well as the desired
length of the Master Key used in a CAST shall be among those supported
by the module in the approved mode."
As a consequence, the salt length in the self test must be at least 16
bytes long for FIPS 140-3 compliance. Switch the self test to use the
only test vector from RFC 6070 that uses salt that is long enough to
fulfil this requirement. Since RFC 6070 does not provide expected
results for PBKDF2 with HMAC-SHA256, use the output from [3], which was
generated with python cryptography, which was tested against the RFC
6070 vectors with HMAC-SHA1.

Fix infinite loops in DSA sign code.
Fixes #20268
Values such as q=1 or priv=0 caused infinite loops when calling
DSA_sign() without these changes.
There are other cases where bad domain parameters may have caused
infinite loops where the retry counter has been added. The simpler case
of priv=0 also hits this case. q=1 caused an infinite loop in the setup.
The max retry value has been set to an arbitrary value of 8 (it is
unlikely to ever do a single retry for valid values).
The minimum q bits was set to an arbitrary value of 128 (160 is still
used for legacy reasons when using 512 bit keys).
Thanks @guidovranken for detecting this, and @davidben for his
insightful analysis.

CMS_decrypt_set1_*(): fix NULL deref on unsuitable content type
Fixes #19975
for CMS_decrypt_set1_pkey_and_peer() in the obvious way,
and a related potential crash in CMS_decrypt_set1_password().
The point is that the input might have an unexpected content type,
so a guard is needed at both places after `ec` is obtained.
Note that in CMS_decrypt_set1_pkey_and_peer() there was
no such ec != NULL guard for
```
if (ris != NULL)
debug = ec->debug;

maybe because it is implied here by ris != NULL.
