This merges all source files into botan_all.cpp, which reduces the build
time by almost 50%. Building outside the strongSwan tree avoids analyzing
Botan with sonarqube.
ldconfig is required, otherwise the library won't be found by
strongSwan in the same session.
Should later be changed to 2.8.0 or a newer stable release.
This also changes how unknown/corrupted memory is handled in the free()
and realloc() hooks in general.
Incorporates changes provided by Thomas Egerer who ran into a similar
issue.
Due to the mangled C++ function names it's tricky to be more specific. The
"leaked" allocations are from a static hashtable containing EC groups.
There is another leak caused by the locking allocator singleton
(triggered by the first function that uses it, usually initialization of
a cipher, but could be a hasher in other test runners), but we can avoid
that with a Botan config option.
Simplifies public key loading and this way unencrypted PKCS#8-encoded
keys can be loaded directly without pkcs8 plugin (code for encrypted
keys could probably later be added, if necessary).
It also simplifies the implementation of private_key_t::get_public_key()
a lot.
Without OID we can't generate an algorithmIdentifier when loading the
key again. And older versions of OpenSSL insist on a public key when
e.g. converting a key to PKCS#8.
Simply unwrapping the ECPrivateKey structure avoids log messages when
parsing other keys in the KEY_ANY case.
Support MD5 in the Botan plugin if supported by Botan.
MD5 is required for RADIUS and obviously EAP-MD5,
and also for non-PKCS#8 encoded, encrypted private keys.
Botan only allows RSA generating keys >= 1,024 bits, which makes
the RSA test suite fail. It is questionable whether it makes
sense to test 768 bit RSA keys anymore. They are too weak
from today's perspective anyway.
This requires config changes if filelog is used with a path that
contains dots. This path must now be defined in the `path` setting of an
arbitrarily named subsection of `filelog`. Without that change the
whole strongswan.conf file will fail to load, which some users might
not notice immediately.
