test/drbgtest.c: Fix error check test

The condition in test_error_checks() was inverted, so the test succeeded
as long as error_check() failed. Incidently, error_check() contained
several bugs that assured it always failed, thus giving overall drbg
test success.

Remove the broken explicit zero check.
RAND_DRBG_uninstantiate() cleanses the data via drbg_ctr_uninstantiate(),
but right after that it resets drbg->data.ctr using RAND_DRBG_set(),
so TEST_mem_eq(zero, sizeof(drbg->data)) always failed.

Avoid errors with a priori inapplicable protocol bounds

The 'MinProtocol' and 'MaxProtocol' configuration commands now silently
ignore TLS protocol version bounds when configurign DTLS-based contexts,
and conversely, silently ignore DTLS protocol version bounds when
configuring TLS-based contexts.  The commands can be repeated to set
bounds of both types.  The same applies with the corresponding

SSL_CTX instances that are created for a fixed protocol version (e.g.
TLSv1_server_method()) also silently ignore version bounds.  Previously

Don't attempt to duplicate the BIO state in SSL_dup

SSL_dup attempted to duplicate the BIO state if the source SSL had BIOs
configured for it. This did not work.

Firstly the SSL_dup code was passing a BIO ** as the destination
argument for BIO_dup_state. However BIO_dup_state expects a BIO * for that
parameter. Any attempt to use this will either (1) fail silently, (2) crash
or fail in some other strange way.

Secondly many BIOs do not implement the BIO_CTRL_DUP ctrl required to make
this work.

Thirdly, if rbio == wbio in the original SSL object, then an attempt is made
to up-ref the BIO in the new SSL object - even though it hasn't been set
yet and is NULL. This results in a crash.

This appears to have been broken for a very long time with at least some of
the problems described above coming from SSLeay. The simplest approach is
to just remove this capability from the function.

Refactor BN_R_NO_INVERSE logic in internal functions

Closes #12129

As described in https://github.com/openssl/openssl/issues/12129 the
readability of the internal functions providing the two alternative
implementations for `BN_mod_inverse()` is a bit lacking.

Both these functions are now completely internal, so we have the
flexibility needed to slightly improve readability and remove
unnecessary NULL checks.

The main changes here are:
- rename `BN_mod_inverse_no_branch()` as `bn_mod_inverse_no_branch()`:
  this function is `static` so it is not even visible within the rest of
  libcrypto. By convention upcase prefixes are reserved for public
  functions.
- remove `if (pnoinv == NULL)` checks in `int_bn_mod_inverse()`: this
  function is internal to the BN module and we can guarantee that all
  callers pass non-NULL arguments.
- `bn_mod_inverse_no_branch()` takes an extra `int *pnoinv` argument, so
  that it can signal if no inverse exists for the given inputs: in this
  way the caller is in charge of raising `BN_R_NO_INVERSE` as it is the
  case for the non-consttime implementation of `int_bn_mod_inverse()`.
- `BN_mod_inverse()` is a public function and must guarantee that the
  internal functions providing the actual implementation receive valid
  arguments. If the caller passes a NULL `BN_CTX` we create a temporary
  one for internal use.
- reorder function definitions in `crypto/bn/bn_gcd.c` to avoid forward
  declaration of `static` functions (in preparation for inlining)
- inline `bn_mod_inverse_no_branch()`.

For each built-in curve, it tests key generation with text output, in
PEM and in DER format, using `explicit` and `named_curve` for parameters
encoding.

The list of built-in curves is static at the moment, as this allows to
differentiate between prime curves and binary curves to avoid failing
when ec2m is disabled.

[crypto/ec] Remove unreachable AVX2 code in NISTZ256 implementation

`crypto/ec/ecp_nistz256.c` contained code sections guarded by a
`ECP_NISTZ256_AVX2` define.

The relevant comment read:

> /*
>  * Note that by default ECP_NISTZ256_AVX2 is undefined. While it's great
>  * code processing 4 points in parallel, corresponding serial operation

Without diminishing the quality of the original submission, it's evident
that this code has been basically unreachable without modifications to
the library source code and is under-tested.

This commit removes these sections from the codebase.

bio printf: Avoid using rounding errors in range check

There is a problem casting ULONG_MAX to double which clang-10 is warning about.
ULONG_MAX typically cannot be exactly represented as a double.  ULONG_MAX + 1
can be and this fix uses the latter, however since ULONG_MAX cannot be
represented exactly as a double number we subtract 65535 from this number,

represented as a double integer without rounding error.  By adding
65536.0 to this number we achive the correct result, which should avoid the
warning.

The addresses a symptom of the underlying problem: we print doubles via an

AES CTR-DRGB: performance improvement

Optimize the the AES-based implementation of the CTR_DRBG
construction, see 10.2.1 in [1].
Due to the optimizations, the code may deviate (more) from the
pseudocode in [1], but it is functional equivalence being decisive
for compliance:

"All DRBG mechanisms and algorithms are described in this document
in pseudocode, which is intended to explain functionality.
The pseudocode is not intended to constrain real-world
implementations." [9 in [1]].

The following optimizations are done:

- Replace multiple plain AES encryptions by a single AES-ECB
  encryption of a corresponding pre-initialized buffer, where
  possible.
  This allows platform-specific AES-ECB support to
  be used and reduces the overhead of multiple EVP calls.

- Replace the generate operation loop (which is a counter
  increment followed by a plain AES encryption) by a
  loop which does a plain AES encryption followed by
  a counter increment. The latter loop is just a description
  of AES-CTR, so we replace it by a single AES-CTR
  encryption.
  This allows for platform-specific AES-CTR support to be used
  and reduces the overhead of multiple EVP calls.
  This change, that is, going from a pre- to a post- counter
  increment, requires the counter in the internal state
  to be kept at "+1" (compared to the pseudocode in [1])
  such that it is in the correct state, when a generate
  operation is called.
  That in turn also requires all other operations to be
  changed from pre- to post-increment to keep functional
  equivalence.

Correct alignment calculation in ssl3_setup_write

The alignment calculation in ssl3_setup_write incorrectly results in an
alignment allowance of
(-SSL3_RT_HEADER_LENGTH) & (SSL3_ALIGN_PAYLOAD - 1) bytes. This equals 3
in almost all cases. The maximum alignment actually used in do_ssl3_write
is (SSL3_ALIGN_PAYLOAD - 1). This equals 7 bytes in almost all cases. So
there is a potential to overrun the buffer by up to 4 bytes.

Fortunately, the encryption overhead allowed for is 80 bytes which
consists of 16 bytes for the cipher block size and 64 bytes for the MAC
output. However the biggest MAC that we ever produce is HMAC-384 which is
48 bytes - so we have a headroom of 16 bytes (i.e. more than the 4 bytes
of potential overrun).

Fix PEM certificate loading that sometimes fails

As described in https://github.com/openssl/openssl/issues/9187, the
loading of PEM certificates sometimes fails if a line of base64
content has the length of a multiple of 254.
The problem is in get_header_and_data(). When such a line with a
length of 254 (or a multiple) has been read, the next read will
only read a newline. Due to this get_header_and_data() expects to be
in the header not in the data area. This commit fixes that by checking
if lines have been read completely or only partially. In case of a
previous partial read, a newline will be ignored.

[BN] harden `BN_copy()` against leaks from memory accesses

`BN_copy()` (and indirectly `BN_dup()`) do not propagate the
`BN_FLG_CONSTTIME` flag: the propagation has been turned on and off a
few times in the past years, because in some conditions it has shown
unintended consequences in some code paths.

Without turning the propagation on once more, we can still improve
`BN_copy()` by avoiding to leak `src->top` in case `src` is flagged with
`BN_FLG_CONSTTIME`.
In this case we can instead use `src->dmax` as the number of words
allocated for `dst` and for the `memcpy` operation.

Barring compiler or runtime optimizations, if the caller provides `src`
flagged as const time and preallocated to a public size, no leak should
happen due to the copy operation.

[EC] harden EC_KEY against leaks from memory accesses

We should never leak the bit length of the secret scalar in the key,
so we always set the `BN_FLG_CONSTTIME` flag on the internal `BIGNUM`
holding the secret scalar.

This is important also because `BN_dup()` (and `BN_copy()`) do not
propagate the `BN_FLG_CONSTTIME` flag from the source `BIGNUM`, and
this brings an extra risk of inadvertently losing the flag, even when
the called specifically set it.

The propagation has been turned on and off a few times in the past
years because in some conditions has shown unintended consequences in
some code paths, so at the moment we can't fix this in the BN layer.

In `EC_KEY_set_private_key()` we can work around the propagation by
manually setting the flag after `BN_dup()` as we know for sure that
inside the EC module the `BN_FLG_CONSTTIME` is always treated
correctly and should not generate unintended consequences.

Setting the `BN_FLG_CONSTTIME` flag alone is never enough, we also have
to preallocate the `BIGNUM` internal buffer to a fixed public size big
enough that operations performed during the processing never trigger
a realloc which would leak the size of the scalar through memory
accesses.

Fixed Length
------------

The order of the large prime subgroup of the curve is our choice for
a fixed public size, as that is generally the upper bound for
generating a private key in EC cryptosystems and should fit all valid
secret scalars.

For preallocating the `BIGNUM` storage we look at the number of "words"
required for the internal representation of the order, and we
preallocate 2 extra "words" in case any of the subsequent processing
might temporarily overflow the order length.

Future work
-----------

A separate commit addresses further hardening of `BN_copy()` (and
indirectly `BN_dup()`).

[EC] Constify internal EC_KEY pointer usage

A pair of internal functions related to EC_KEY handling could benefit
from declaring `EC_KEY *` variables as `const`, providing clarity for
callers and readers of the code, in addition to enlisting the compiler
in preventing some mistakes.

(cherry picked from commit cd701de96a147260c2290d85af8a0656120a8ff8)

In master `id2_ECParameters` and most of the ASN1 public functions have
been properly constified in their signature.

Unfortunately this has been deemed not doable in a patch release for
1.1.1 as, in subtle ways, this would break API compatibility.
See the discussion at https://github.com/openssl/openssl/pull/9347 for
more details about this.

This constification commit should still be portable w.r.t. our criteria,
as the constification happens only on internal functions.

The fix here is to explicitly discard the const qualifier before the
call to `i2d_ECParameters`, which should be safe anyway because we can
expect `i2d_ECParameters()` to treat the first argument as if it was
const.
