It also assumes that you have an environment variable BORING_RUNNER_DIR

This has only been tested with a very old version of BoringSSL (from commit

be due to bugs in OpenSSL, some might be due to features that BoringSSL has

Integrate BoringSSL shim

The BoringSSL test suite contains numerous tests which OpenSSL does not.

The BoringSSL test runner uses a shim to launch the library and execute the
tests. This is a version of the BoringSSL shim converted to compile against
OpenSSL instead.

This is primarily based on the work of David Benjamin from the BoringSSL
project who did most of the necessary conversion. It also includes a few
other tweaks for opacity changes etc.

This is based on a *very* old version of BoringSSL from commit f277add6c.
That was the last commit known to work with this patched shim. Later
versions may also work but lots of merge conflicts occur when trying to
bring it up to date.

At the moment this has not been integrated into the build system. There is
a very simple standalone makefile in the ossl_shim directory which should
be executed directly before tyring to use the shim.

Ensure that libcrypto and libssl do not unload until the process exits

Because we use atexit() to cleanup after ourselves, this will cause a

atexit() handler may no longer be there.

Most modern atexit() implementations can handle this, however there are
still difficulties if libssl gets unloaded before libcrypto, because of
the atexit() callback that libcrypto makes to libssl.

The most robust solution seems to be to ensure that libcrypto and libssl
never unload. This is done by simply deliberately leaking a dlopen()
reference to them.

records.

Reviewed-by: Richard Levitte <levitte@openssl.org>

Fix read_ahead

The function ssl3_read_n() takes a parameter |clearold| which, if set,
causes any old data in the read buffer to be forgotten, and any unread data
to be moved to the start of the buffer. This is supposed to happen when we
first read the record header.

However, the data move was only taking place if there was not already
sufficient data in the buffer to satisfy the request. If read_ahead is set
then the record header could be in the buffer already from when we read the
preceding record. So with read_ahead we can get into a situation where even
though |clearold| is set, the data does not get moved to the start of the
read buffer when we read the record header. This means there is insufficient
room in the read buffer to consume the rest of the record body, resulting in
an internal error.

This commit moves the |clearold| processing to earlier in ssl3_read_n()
to ensure that it always takes place.
