Sometimes the error handling returns an ASN1_STRING
object in *out although that was not passed in by the
caller, and sometimes the error handling deletes the
ASN1_STRING but forgets to clear the *out parameter.
Therefore the caller has no chance to know, if the leaked
object in *out shall be deleted or not.
This may cause a use-after-free error e.g. in asn1_str2type:

If a malformed config file is provided such as the following:
openssl_conf = openssl_init
[openssl_init]
providers = provider_sect
[provider_sect]
= provider_sect
The config parsing library will crash overflowing the stack, as it
recursively parses the same provider_sect ad nauseum.
Prevent this by maintaing a list of visited nodes as we recurse through
referenced sections, and erroring out in the event we visit any given
section node more than once.
Note, adding the test for this revealed that our diagnostic code
inadvertently pops recorded errors off the error stack because
provider_conf_load returns success even in the event that a
configuration parse failed. The call path to provider_conf_load has been
updated in this commit to address that shortcoming, allowing recorded
errors to be visibile to calling applications.

Currently, a provider is activated from our config file using the
activate parameter. However, the presence of the config parameter is
sufficient to trigger activation, leading to a counterintuitive
situation in which setting "activate = 0" still activates the provider
Make activation more intuitive by requiring that activate be set to one
of yes|true|1 to trigger activation. Any other value, as well as
omitting the parameter entirely, prevents activation (and also maintains
backward compatibility.
It seems a bit heavyweight to create a test specifically to validate the
plurality of these settings. Instead, modify the exiting openssl config
files in the test directory to use variants of these settings, and
augment the default.cnf file to include a provider section that is
explicitly disabled

The [LP64D ABI][1] requires the floating-point registers f24-f31
(aka fs0-fs7) callee-saved. The low 64 bits of a LSX/LASX vector
register aliases with the corresponding FPR, so we must save and restore
the callee-saved FPR when we writes into the corresponding vector
register.
This ABI breakage can be easily demonstrated by injecting the use of a
saved FPR into the test in bio_enc_test.c:
static int test_bio_enc_chacha20(int idx)
{
register double fs7 asm("f31") = 114.514;
asm("#optimize barrier":"+f"(fs7));
return do_test_bio_cipher(EVP_chacha20(), idx) && fs7 == 114.514;
}
So fix it. To make the logic simpler, jump into the scalar
implementation earlier when LSX and LASX are not enumerated in AT_HWCAP,
or the input is too short.

In param_build.c, the functions OSSL_PARAM_BLD_push_utf8_string() and

strlen() might be too large (it is stored in an intermediate "int"),
so check for that.
There are analogous functions in params.c, but they do not use an
intermediate "int" to store the size_t returned by strlen(). So there
is some inconsistency between the implementations.

sscanf can return -1 on an empty input string. We need to appropriately
handle such an invalid case.
The instance in OSSL_HTTP_parse_url could cause an uninitialised read of
sizeof(unsigned int) bytes (typically 4). In many cases this uninit read
will immediately fail on the following check (i.e. if the read value
>65535).
If the top 2 bytes of a 4 byte unsigned int are zero then the value will
be <=65535 and the uninitialised value will be returned to the caller and
could represent arbitrary data on the application stack.
The OpenSSL security team has assessed this issue and consider it to be
a bug only (i.e. not a CVE).

The little-endian optimization is doing some type-punning in a way
violating the C standard aliasing rule by loading or storing through a
lvalue with type "unsigned int" but the memory location has effective
type "unsigned long" or "unsigned long long" (BN_ULONG). Convert these
accesses to use memcpy instead, as memcpy is defined as-is "accessing
through the lvalues with type char" and char is aliasing with all types.
GCC does a good job to optimize away the temporary copies introduced
with the change. Ideally copying to a temporary unsigned int array,
doing the calculation, and then copying back to `r_d` will make the code
look better, but unfortunately GCC would fail to optimize away this
temporary array then.
I've not touched the LE optimization in BN_nist_mod_224 because it's
guarded by BN_BITS2!=64, then BN_BITS2 must be 32 and BN_ULONG must be
unsigned int, thus there is no aliasing issue in BN_nist_mod_224.

We already check for an excessively large P in DH_generate_key(), but not in
DH_check_pub_key(), and none of them check for an excessively large Q.
This change adds all the missing excessive size checks of P and Q.
It's to be noted that behaviours surrounding excessively sized P and Q
differ. DH_check() raises an error on the excessively sized P, but only
sets a flag for the excessively sized Q. This behaviour is mimicked in
DH_check_pub_key().

When successful, ossl_X509_ALGOR_from_nid() returns a pointer to an
X509_ALGOR object. Inside ossl_X509_ALGOR_from_nid(),
X509_ALGOR_set0() is called, and this passes ownership of the ASN1
object "los" (label octet string) to the X509_ALGOR object. When
ossl_X509_ALGOR_from_nid() fails, ownership has not been passed on and
we need to free "los".
Change the scope of "los" and ensure it is freed on failure (on
success, set it to NULL so it is not freed inside the function).

The RISC-V vector extension comes with an implementation-defined
number of bits per vector register (VLEN), which can be read out at
run-time using the CSR 'vlenb' (which returns VLEN/8) followed by a
multiplication by 8 (to convert bytes to bits).
This patch introduces a RISC-V capability 'V' to specify the
availability of the vector extension. If this extension is found at
run-time, then we read out VLEN as described above and cache it.
Caching ensures that we only read the CSR once at startup.
This is necessary because reading out CSR can be expensive
(e.g. if CSR readout is implemented using trap-and-emulate).
Follow-up patches can make use of VLEN and chose the best strategy
based on the available length of the vector registers.

evp_cipher_init_internal() takes a params array argument and this is processed
late in the initialisation process for some ciphers (AEAD ones).
This means that changing the IV length as a parameter will either truncate the
IV (very bad if SP 800-38d section 8.2.1 is used) or grab extra uninitialised
bytes.
Truncation is very bad if SP 800-38d section 8.2.1 is being used to
contruct a deterministic IV. This leads to an instant loss of confidentiality.
Grabbing extra bytes isn't so serious, it will most likely result in a bad
decryption.

The 'rand_generate' method is not well suited for being used with
weak entropy sources in the 'get_entropy' callback, because the
caller needs to provide a preallocated buffer without knowing
how much bytes are actually needed to collect the required entropy.
Instead we use the 'rand_get_seed' and 'rand_clear_seed' methods
which were exactly designed for this purpose: it's the callee who
allocates and fills the buffer, and finally cleans it up again.
The 'rand_get_seed' and 'rand_clear_seed' methods are currently
optional for a provided random generator. We could fall back to
using 'rand_generate' if those methods are not implemented.
However, imo it would be better to simply make them an officially
documented requirement for seed sources.
