Unfortunately, we can't just add the generated C file to the sources in
Makefile.am as the linker would remove that object file when it notices
that no symbol in it is ever referenced. So we include it in the file
that contains the library initialization, which will definitely be
referenced by the executable.
This allows building an almost stand-alone static version of e.g. charon
when building with `--enable-monolithic --enable-static --disable-shared`
(without `--disable-shared` libtool will only build a version that links
the libraries dynamically). External libraries (e.g. gmp or openssl) are
not linked statically this way, though.
If the IKEv2 initiator acting as a TNC server receives invalid TNC measurements
from the IKEv2 responder acting as a TNC clienti, the exchange of PB-TNC batches
is continued until the IKEv2 responder acting as a TNC server has also finished
its TNC measurements.
In the past if these measurements in the other direction were correct
the IKEv2 responder acting as EAP server declared the IKEv2 EAP authentication
successful and the IPsec connection was established even though the TNC
measurement verification on the EAP peer side failed.
The fix adds an "allow" group membership on each endpoint if the corresponding
TNC measurements of the peer are successful. By requiring a "allow" group
membership in the IKEv2 connection definition the IPsec connection succeeds
only if the TNC measurements on both sides are valid.
Handling the result for enum_from_name() is difficult, as checking for
negative return values requires a cast if the enum type is unsigned. The new
signature clearly differentiates lookup result from lookup value.
Further, this actually allows to convert real -1 enum values, which could not
be distinguished from "not-found" and the -1 return value.
This also fixes several clang warnings where enums are unsigned.
The flag is required to convince libtool on Cygwin to build DLLs. But on
Windows these shared libraries can not have undefined symbols, so we have to
link them explicitly to the libraries they reference.
For plugins this is currently not done, so only the monolithic build is
supported. The plugin loader wouldn't be able to load DLLs anyway, as
it tries to load files that don't exist on Cygwin.
INCLUDES are now deprecated and throw warnings when using automake 1.13.
We now also differentiate AM_CPPFLAGS and AM_CFLAGS, where includes and
defines are passed to AM_CPPFLAGS only.
