dereferenced when both parameter arrays ended with the same key

Neil Horman 837592dcd9 Fix buggy stringop-overflow error on s390
Despite some recent changes to our s390 builds, we're still seeing
errors due to some stringop-overflow warnings:
https://github.com/openssl/openssl/actions/runs/15748518222/job/44389197443

It appears to be caused because the static analysis that gcc preforms in
gcc 12 (the version of the compiler on our s390 runner), fails to infer
the proper sizes of the buffer on which we do the reverse memcpy in
swap_copy(), resulting in warnings, which on --strict-warnings builds,
breaks us.

Fix it by using inlen rather than outlen to limit the copy length,
adjusting it if need be to match the size of the output buffer in
le_copy().  This allows the compiler to properly infer the array length
constraints and suppress the warnings.

Ingo Franzki 9a788281d9 Silence -Wstringop-overflow warnings with gcc 14 on s390x
Compiling OpenSSL on s390x with gcc 14 (i.e. in Fedora 41) shows several
-Wstringop-overflow warnings in providers/implementations/rands/drbg_ctr.c
and test/params_api_test.c.

Add explicit length checks to let the compiler know that it won't overrun
the buffer. This also silences the warnings.

Nicolas Blais-Miko a0ff819e53 Fix silent error in EVP_CIPHER_CTX_get_updated_iv.
Added new params API function OSSL_PARAM_set_octet_string_or_ptr to only
call the correct setter for OSSL_CIPHER_PARAM_IV and OSSL_CIPHER_PARAM_UPDATED_IV.
Both OSSL_PARAM_set_octet_string and OSSL_PARAM_set_octet_ptr could be called with
only one expected to succeed. This would put a silent error on the error stack when
calling EVP_CIPHER_CTX_get_updated_iv.

Fixes #27117

Neil Horman 806bbafe2d Check appropriate OSSL_PARAM_get_* functions for NULL
The base type OSSL_PARAM getters will NULL deref if they are initalized
as null.  Add NULL checks for those parameters that have no expectation
of returning null (int32/64/uint32/64/BN).  Other types can be left as
allowing NULL, as a NULL setting may be meaningful (string, utf8str,
octet string, etc).

They are due to an additional conversion copy.  Remove this copy to solve the

Shane Lontis 884314cab7 Add OSSL_PARAM_dup() and OSSL_PARAM_merge().
These functions are prerequisites for implementing EVP_PKEY_todata().

OSSL_PARAM_dup() is required to make a deep copy of the exported
params (since the provider export() uses a OSSL_PARAM_BLD which throws away the
data after the call), and then use OSSL_PARAM_merge() to add some additional params
that can be passed to the EVP_PKEY_todata().

Richard Levitte 247a1786e2 OSSL_PARAM: Correct the assumptions on the UTF8 string length
When the string "ABCDEFGH" is passed, what's considered its data, this?

    { 'A', 'B', 'C', 'D', 'E', 'F', 'G', 'H' }

or this?

    { 'A', 'B', 'C', 'D', 'E', 'F', 'G', 'H', '\0' }

If it's passed as a pass phrase, should the terminating NUL byte be
considered part of the pass phrase, or not?

Our treatment of OSSL_PARAMs with the data type OSSL_PARAM_UTF8_STRING
set the length of the string to include the terminating NUL byte,
which is quite confusing.  What should the recipient of such a string
believe?

Instead of perpetuating this confusion, we change the assumption to
set the OSSL_PARAM to the length of the string, not including the
terminating NUL byte, thereby giving it the same value as a strlen()
call would give.

Pauli 7ffbd7ca96 OSSL_PARAM helper functions.
Provide a number of functions to allow parameters to be set and
retrieved in a type safe manner.  Functions are provided for many
integral types plus double, BIGNUM, UTF8 strings and OCTET strings.

All of the integer functions will widen the parameter data as
required.  This permits a degree of malleability in the parameter
definition.  For example a type can be changed from a thirty two bit
integer to a sixty four bit one without changing application code.
Only four and eight byte integral sizes are supported here.

A pair of real functions are available for doubles.

A pair of functions is available for BIGNUMs.  These accept any sized
unsigned integer input and convert to/from a BIGNUM.

For each OCTET and UTF8 strings, four functions are defined.  This
provide get and set functionality for string and for pointers to
strings.  The latter avoiding copies but have other inherent risks.

Finally, some utility macros and functions are defined to allow
OSSL_PARAM definition arrays to be specified in a simple manner.
There are two macro and one function for most types.  The exception
being BIGNUM, for which there is one macro and one function.
