a935791d54 Rework and make DEBUG macros consistent.
Remove unused -DCONF_DEBUG and -DBN_CTX_DEBUG.

Rename REF_PRINT to REF_DEBUG for consistency, and add a new
tracing category and use it for printing reference counts.

Rename -DDEBUG_UNUSED to -DUNUSED_RESULT_DEBUG

Fix BN_DEBUG_RAND so it compiles and, when set, force DEBUG_RAND to
be set also.

Rename engine_debug_ref to be ENGINE_REF_PRINT also for consistency.

0d40ca47bd bn: Add fixed length (n=6), unrolled PPC Montgomery Multiplication
Overall improvement for p384 of ~18% on Power 9, compared to existing
Power assembling code.  See comment in code for more details.

Multiple unrolled versions could be generated for values other than
6.  However, for TLS 1.3 the only other ECC algorithms that might use
Montgomery Multiplication are p256 and p521, but these have custom
algorithms that don't use Montgomery Multiplication.  Non-ECC
algorithms are likely to use larger key lengths that won't fit into
the n <= 10 length limitation of this code.

848af5e8fe Drop libimplementations.a
libimplementations.a was a nice idea, but had a few flaws:

1.  The idea to have common code in libimplementations.a and FIPS
    sensitive helper functions in libfips.a / libnonfips.a didn't
    catch on, and we saw full implementation ending up in them instead
    and not appearing in libimplementations.a at all.

2.  Because more or less ALL algorithm implementations were included
    in libimplementations.a (the idea being that the appropriate
    objects from it would be selected automatically by the linker when
    building the shared libraries), it's very hard to find only the
    implementation source that should go into the FIPS module, with
    the result that the FIPS checksum mechanism include source files
    that it shouldn't

To mitigate, we drop libimplementations.a, but retain the idea of
collecting implementations in static libraries.  With that, we not
have:

libfips.a

    Includes all implementations that should become part of the FIPS
    provider.

liblegacy.a

    Includes all implementations that should become part of the legacy
    provider.

libdefault.a

    Includes all implementations that should become part of the
    default and base providers.

With this, libnonfips.a becomes irrelevant and is dropped.
libcommon.a is retained to include common provider code that can be
used uniformly by all providers.

788a72e92f Increase minimum clang version requirement for rsaz-avx512.pl
The reason is that clang-6 does not enable proper -march flags by
default for assembly modules (rsaz-avx512.pl requires avx512ifma, avx512dq,
avx512vl, avx512f). This is not true for newer clang versions - clang-7 and
further work ok.

For older clang versions users who want to get optimization from this
file, we have a note in the OPENSSL_ia32cap.pod with the workaround that
proposes having a wrapper that forces using external assembler.

d4bf0d57a8 Flag RSA secret BNs as consttime on keygen and checks
<https://github.com/openssl/openssl/pull/11765> switched the default
code path for keygen.

External testing through TriggerFlow highlighted that in several places
we failed (once more!) to set the `BN_FLG_CONSTTIME` flag on critical
secret values (either long term or temporary values).

This commit tries to make sure that the secret BN values inside the
`rsa struct` are always flagged on creation, and that temporary values
derived from these secrets are flagged when allocated from a BN_CTX.

5d8b3a3ef2 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()`.

DH_set0_pqg() is now responsible for caching the nid, q and length.

DH with or without named safe prime groups now default to using the maximum private key length (BN_num_bits(q) - 1)
when generating a DH private key. The code is now shared between fips and non fips mode for DH key generation.

The OSSL_PKEY_PARAM_DH_PRIV_LEN parameter can be used during keygen to override the maximum private key length to be
in the range (2 * strength ... bits(q) - 1). Where the strength depends on the length of p.

Added q = (p - 1) / 2 safe prime BIGNUMS so that the code is data driven (To simplify adding new names).
The BIGNUMS were code generated.

2d9167ed0b [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.

32be631ca1 Do not silently truncate files on perlasm errors
If one of the perlasm xlate drivers crashes, OpenSSL's build will
currently swallow the error and silently truncate the output to however
far the driver got. This will hopefully fail to build, but better to
check such things.

Handle this by checking for errors when closing STDOUT (which is a pipe
to the xlate driver).

"adcx %rbp, $out" since %rbp is always 0, and carry is
also zero, therefore that is a no-op.

There is an overflow bug in the x64_64 Montgomery squaring procedure used in

suggests that attacks against 2-prime RSA1024, 3-prime RSA1536, and DSA1024 as a
result of this defect would be very difficult to perform and are not believed
likely. Attacks against DH512 are considered just feasible. However, for an
attack the target would have to re-use the DH512 private key, which is not
recommended anyway. Also applications directly using the low level API
BN_mod_exp may be affected if they use BN_FLG_CONSTTIME.

PR https://github.com/openssl/openssl/pull/10122 introduced changes to
the BN_gcd function and the control logic inside it accessed `g->d[0]`
irrespective of `g->top`.

When BN_add is called, in case the result is zero, `BN_zero` is called.
The latter behaves differently depending on the API compatibility level
flag: normally `g->d[0]` is cleared but in `no-deprecated` builds only
`g->top` is set to zero.

This commit uses bitwise logic to ensure that `g` is treated as zero if
`g->top` is zero, irrespective of `g->d[0]`.

8eba6de59e Unify BN_rshift design
This commit aims at refactoring the `BN_rshift` by making it a wrapper

`BN_lshift`, as suggested in the discussion at
https://github.com/openssl/openssl/pull/10122#discussion_r332474277 .

As described in the code, by refactoring this function, `BN_rshift`
provides a constant-time behavior for sufficiently[!] zero-padded inputs
under the following assumptions: `|n < BN_BITS2|` or `|n / BN_BITS2|`
being non-secret.

Notice that `BN_rshift` returns a canonical representation of the
BIGNUM, if a `fixed_top` representation is required, the caller should
call `bn_rshift_fixed_top` instead.

The FIPS provider module is built from providers/fips/*.c and linked
with libimplementations, libcommon and libfips.

The Legacy provider module is built from providers/legacy/*.c and
linked with liblegacy, libcommon and libcrypto.
If module building is disabled, the object files from liblegacy and
libcommon are added to libcrypto and the Legacy provider becomes a
built-in provider.

The Default provider module is built-in, so it ends up being linked
with libimplementations, libcommon and libnonfips.  For libcrypto in
form of static library, the object files from those other libraries
are simply being added to libcrypto.

ae4186b004 Fix header file include guard names
Make the include guards consistent by renaming them systematically according
to the naming conventions below

For the public header files (in the 'include/openssl' directory), the guard
names try to match the path specified in the include directives, with
all letters converted to upper case and '/' and '.' replaced by '_'. For the
private header files files, an extra 'OSSL_' is added as prefix.

706457b7bd Reorganize local header files
Apart from public and internal header files, there is a third type called
local header files, which are located next to source files in the source
directory. Currently, they have different suffixes like

  '*_lcl.h', '*_local.h', or '*_int.h'

This commit changes the different suffixes to '*_local.h' uniformly.

25f2138b0a Reorganize private crypto header files
Currently, there are two different directories which contain internal
header files of libcrypto which are meant to be shared internally:

While header files in 'include/internal' are intended to be shared
between libcrypto and libssl, the files in 'crypto/include/internal'
are intended to be shared inside libcrypto only.

To make things complicated, the include search path is set up in such
a way that the directive #include "internal/file.h" could refer to
a file in either of these two directoroes. This makes it necessary
in some cases to add a '_int.h' suffix to some files to resolve this
ambiguity:

  #include "internal/file.h"      # located in 'include/internal'
  #include "internal/file_int.h"  # located in 'crypto/include/internal'

This commit moves the private crypto headers from

  'crypto/include/internal'  to  'include/crypto'

As a result, the include directives become unambiguous

  #include "internal/file.h"       # located in 'include/internal'
  #include "crypto/file.h"         # located in 'include/crypto'

hence the superfluous '_int.h' suffixes can be stripped.

The files 'store_int.h' and 'store.h' need to be treated specially;
they are joined into a single file.

1aa89a7a3a Unify all assembler file generators
They now generally conform to the following argument sequence:

    script.pl "$(PERLASM_SCHEME)" [ C preprocessor arguments ... ] \
              $(PROCESSOR) <output file>

However, in the spirit of being able to use these scripts manually,
they also allow for no argument, or for only the flavour, or for only
the output file.  This is done by only using the last argument as
output file if it's a file (it has an extension), and only using the
first argument as flavour if it isn't a file (it doesn't have an
extension).

While we're at it, we make all $xlate calls the same, i.e. the $output
argument is always quoted, and we always die on error when trying to
start $xlate.

There's a perl lesson in this, regarding operator priority...

This will always succeed, even when it fails:

    open FOO, "something" || die "ERR: $!";

The reason is that '||' has higher priority than list operators (a
function is essentially a list operator and gobbles up everything
following it that isn't lower priority), and since a non-empty string
is always true, so that ends up being exactly the same as:

    open FOO, "something";

This, however, will fail if "something" can't be opened:

    open FOO, "something" or die "ERR: $!";

The reason is that 'or' has lower priority that list operators,
i.e. it's performed after the 'open' call.
