These functions are:

    SSL_use_certificate_file
    SSL_use_RSAPrivateKey_file
    SSL_use_PrivateKey_file
    SSL_CTX_use_certificate_file
    SSL_CTX_use_RSAPrivateKey_file
    SSL_CTX_use_PrivateKey_file
    SSL_use_certificate_chain_file

Internally, they use BIO_s_file(), which is defined and implemented at
all times, even when OpenSSL is configured no-stdio.

The macros that produce PEM_write_FOO() andd PEM_read_FOO() only do so
unless 'no-stdio' has been configured.  mkdef.pl should mimic that by
marking those functions with the "STDIO" algo.

These were guarded by $disabled{tests}.  However, 'tests' is disabled
if we configure 'no-stdio', which means that we don't detect the lack
of OPENSSL_NO_STDIO guards in our public header files.  So we move the
generation and build of test/buildtest_*.c to be unconditional.

Should result in more accurate header file coverage, see
https://github.com/eddyxu/cpp-coveralls/issues/54Reviewed-by: NKurt Roeckx <kurt@openssl.org>

Run tests with coverage and report to coveralls.io

For simplicity, this currently only adds a single target in a
configuration that attempts to maximize coverage. The true CI coverage
from all the various builds may be a little larger.

The coverage run has the following configuration:
- no-asm: since we can't track asm coverage anyway, might as well measure the
  non-asm code coverage.
- Enable various disabled-by-default options:
  - rc5
  - md2
  - ec_nistp_64_gcc_128
  - ssl3
  - ssl3-method
  - weak-ssl-ciphers

Finally, observe that no-pic implies no-shared, and therefore running
both builds in the matrix is redundant.

Baroque, almost uncommented code triggers behaviour which is undefined
by the C standard. You might quite reasonably not care that the code was
broken on ones-complement machines, but if we support a ubsan build then
we need to at least pretend to care.

It looks like the special-case code for 64-bit big-endian is going to
behave differently (and wrongly) on wrap-around, because it treats the
values as signed. That seems wrong, and allows replay and other attacks.
Surely you need to renegotiate and start a new epoch rather than
wrapping around to sequence number zero again?

DTLSv1_client_method() is deprecated, but it was the only way to obtain
DTLS1_BAD_VER support. The SSL_OP_CISCO_ANYCONNECT hack doesn't work with
DTLS_client_method(), and it's relatively non-trivial to make it work without
expanding the hack into lots of places.

So deprecate SSL_OP_CISCO_ANYCONNECT with DTLSv1_client_method(), and make
it work with SSL_CTX_set_{min,max}_proto_version(DTLS1_BAD_VER) instead.

DTLS version numbers are strange and backwards, except DTLS1_BAD_VER so
we have to make a special case for it.

This does leave us with a set of macros which will evaluate their arguments
more than once, but it's not a public-facing API and it's not like this is
the kind of thing where people will be using DTLS_VERSION_LE(x++, y) anyway.

Commit d8e8590e ("Fix missing return value checks in SCTP") made the
DTLS handshake fail, even for non-SCTP connections, if
SSL_export_keying_material() fails. Which it does, for DTLS1_BAD_VER.

Apply the trivial fix to make it succeed, since there's no real reason
why it shouldn't even though we never need it.
