This adds an explicit limit to the size of an X509_NAME structure. Some
part of OpenSSL (e.g. TLS) already effectively limit the size due to
restrictions on certificate size.

Don't use an uninitialised variable in srp application
The srp application created an uninitialised DB_ATTR object and then
passed it to the load_index function which attempted to read it. A
DB_ATTR object only contains a single field called "unique_subject".
AFAICT this attribute is unused in the SRP case, and therefore it would be
better to pass a NULL DB_ATTR to load_index (which handles that case
gracefully).

Avoid a NULL ptr deref if group is not set
We should only copy parameters and keys if the group is set. Otherwise
they don't really make any sense. Previously we copied the private key
regardless of whether the group was set...but if it wasn't a NULL ptr
deref could occur. It's unclear whether we could ever get into that
situation, but since we were already checking it for the public key we
should be consistent.

VMS: It seems DEC C doesn't handle certain header files quite right
With DEC C on VMS, you can use __DECC_INCLUDE_PROLOGUE.H and
__DECC_INCLUDE_EPILOGUE.H to include some DEC C specific features or

It seems, however, that the current version of the compiler requires

Add aliases for des-ede-ecb and des-ede3-ecb ciphers.
Currently we can get all block ciphers with
EVP_get_cipherbyname("<alg_name>-<block-mode-name>")
for example, by names "aes-128-ecb" or "des-ede-cbc".
I found a problem with des-ede-ecb and des-ede3-ecb ciphers as
they can be accessed only with names:
EVP_get_cipherbyname("des-ede")
EVP_get_cipherbyname("des-ede3")
It breaks the general concept.
In this patch I add aliases which allow to use names:
EVP_get_cipherbyname("des-ede-ecb")
EVP_get_cipherbyname("des-ede3-ecb")
in addition to the currently used names.

Make BIO_sock_error return a proper error code when getsockopt fails
BIO_sock_error() returned 1 when getsockopt() fails when it should

Additionally, the optlen parameter to getsockopt() has to point at
the size of the area that the optval parameter points at rather than
zero. Some systems may forgive it being zero, but others don't.
The traditional private key encryption algorithm doesn't function
properly if the IV length of the cipher is zero. These ciphers

Future proof build_chain() in x509_vfy.c
Coverity reports a potential NULL deref when "2 0 0" DANE trust-anchors
from DNS are configured via SSL_dane_tlsa_add() and X509_STORE_CTX_init()
is called with a NULL stack of untrusted certificates.
Since ssl_verify_cert_chain() always provideds a non-NULL stack of
untrusted certs, and no other code path enables DANE, the problem
can only happen in applications that use SSL_CTX_set_cert_verify_callback()
to implement their own wrappers around X509_verify_cert() passing
only the leaf certificate to the latter.
Regardless of the "improbability" of the problem, we do need to
ensure that build_chain() handles this case correctly.
