With the introduction of PT-TLS, we started sending TLS close notifies after
the application layer completes (7bbf7aa9). While this makes sense for TCP based
transports, it is not required in EAP methods. In EAP, handshake completion
can be directly signaled using the outer EAP-SUCCESS message. This also saves
one round-trip in the EAP exchange.
Windows 7/8 does not seem to like TLS close notifies at all in EAP, and either
stalls (EAP-TTLS) or disconnects (PEAP).
Fixes#556.
A type is returned only if upper layers successfully created a record, that is
returns NEED_MORE. If we do not check for the return value, we might check a
previous record or the uninitialized type variable and falsely reset the
sequence number.
When running the tests in GDB the working directory apparently is
different. With the relative path used previously the plugins would not
be found and those installed on the system would get used.
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.
While a hardcoded 1.2 version is fine when we offer that in Client Hello, we
should include the actually offered version if it has been reduced before
starting the exchange.
Fixes fragment reassembling if a buffer contains more than one record, but
the last record contains a partial TLS record header. Thanks to Nick Saunders
and Jamil Nimeh for identifying this issue and providing a fix for it.
To better separate the code path for different TLS versions and modes of
operation, we introduce a TLS AEAD abstraction. We provide three implementations
using traditional transforms, and get prepared for TLS AEAD modes.
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.
