RFC5753 requires that we omit parameters for AES key wrap and set them
to NULL for 3DES wrap. OpenSSL decrypt uses the received algorithm
parameters so can transparently handle either form.

The function int_rsa_verify is an internal function used for verifying an
RSA signature. It takes an argument |dtype| which indicates the digest type
that was used. Dependant on that digest type the processing of the
signature data will vary. In particular if |dtype == NID_mdc2| and the
signature data is a bare OCTETSTRING then it is treated differently to the
default case where the signature data is treated as a DigestInfo (X509_SIG).
Due to a missing "else" keyword the logic actually correctly processes the
OCTETSTRING format signature first, and then attempts to continue and
process it as DigestInfo. This will invariably fail because we already know
that it is a bare OCTETSTRING.
This failure doesn't actualy make a real difference because it ends up at
the |err| label regardless and still returns a "success" result. This patch
just cleans things up to make it look a bit more sane.

Even though SOCKET is effectively declared as (void *) on Windows, it's
not actually a pointer, but an index within per-process table of
kernel objects. The table size is actually limited and its upper limit
is far below upper limit for signed 32-bit integer. This is what makes

If we use BIO_new_file(), on Windows it'll jump through hoops to work
around their unusual charset/Unicode handling. it'll convert a UTF-8

If you use BIO_read_filename(), it doesn't do this. Shouldn't it be

There are a couple of minor fixes here:
1) Handle the case when RegisterEventSource() fails (which it may for
various reasons) and do the work of logging the event only if it succeeds.
2) Handle the case when ReportEvent() fails and do our best in debug builds
to at least attempt somehow indicate that something has gone wrong. The
typical situation would be someone running tools like DbMon, DBWin32,
DebugView or just having the debugger attached. The intent is to make sure
that at least some data will be captured so that we can save hours and days
of debugging time.
3) Minor fix to change the MessageBox() flag to MB_ICONERROR. Though the
value of MB_ICONERROR is the same value as MB_ICONSTOP, the intent is
better conveyed by using MB_ICONERROR.
Testing performed:
1) Clean compilation for debug-VC-WIN32 and VC-WIN32.
2) Good test results (nmake -f ms\ntdll.mak test) for debug-VC-WIN32 and
VC-WIN32.
3) Stepped through relevant changes using WinDBG and exercised the impacted
code paths.

In master we have the function OPENSSL_clear_free(x,y), which immediately
returns if x == NULL. In <=1.0.2 this function does not exist so we have to
do:
OPENSSL_cleanse(x, y);
OPENSSL_free(x);
However, previously, OPENSSL_cleanse did not check that if x == NULL, so
the real equivalent check would have to be:
if (x != NULL)
OPENSSL_cleanse(x, y);
OPENSSL_free(x);
It would be easy to get this wrong during cherry-picking to other branches
and therefore, for safety, it is best to just ensure OPENSSL_cleanse also
checks for NULL.

it must be:

This reduces memory fragmentation and make it impossible to accidentally
set a mandatory field to NULL.
This currently only works for SEQUENCE and since it is equivalent to

This provides support for building in the EDK II reference implementation
of UEFI. Most UEFI firmware in existence uses OpenSSL for implementing
the core cryptographic functionality needed for Secure Boot.
This has always previously been handled with external patches to OpenSSL
but we are now making a concerted effort to eliminate those.
In this mode, we don't actually use the OpenSSL makefiles; we process
the MINFO file generated by 'make files' and incorporate it into the
EDK2 build system.
Since EDK II builds for various targets with varying word size and we
need to have a single prepackaged configuration, we deliberately don't
hard-code the setting of SIXTY_FOUR_BIT vs. THIRTY_TWO_BIT in
opensslconf.h. We bypass that for OPENSSL_SYS_UEFI and allow EDK II
itself to set those, depending on the architecture.
For x86_64, EDK II sets SIXTY_FOUR_BIT and thus uses 'long long' for the
64-bit type, even when building with GCC where 'long' is also 64-bit. We
do this because the Microsoft toolchain has 32-bit 'long'.
