Motivation:
NPN has been superseeded by ALPN
SPDY has been superseeded by HTTP/2 and Chrome has dropped support in 2016
Those protocols are deprecated and most likely no longer used at large.
Modifications:
Remove NPN and SPDY code.
`ApplicationProtocolConfig.Protocol` enum is left with 2 values: NONE and ALPN, as this might be more explicit than a boolean and would be more versatile should a new negotiation protocol appear.
Result:
Removed dead code
Motivation:
The behavior for SelectorFailureBehavior and SelectedListenerFailureBehavior enum values are not clear. Additional comments would clarify the expected behavior.
Modifications:
- Add comments for each value in SelectedListenerFailureBehavior and SelectorFailureBehavior which clarify the expected behavior
Result:
The behavior of SelectedListenerFailureBehavior and SelectorFailureBehavior are more clearly communicated.
Motivation:
To support HTTP2 we need APLN support. This was not provided before when using OpenSslEngine, so SSLEngine (JDK one) was the only bet.
Beside this CipherSuiteFilter was not supported
Modifications:
- Upgrade netty-tcnative and make use of new features to support ALPN and NPN in server and client mode.
- Guard against segfaults after the ssl pointer is freed
- support correctly different failure behaviours
- add support for CipherSuiteFilter
Result:
Be able to use OpenSslEngine for ALPN / NPN for server and client.
Motivation:
When ALPN/NPN is disabled, a user has to instantiate a new
ApplicationProtocolConfig with meaningless parameters.
Modifications:
- Add ApplicationProtocolConfig.DISABLED, the singleton instance
- Reject the constructor calls with Protocol.NONE, which doesn't make
much sense because a user should use DISABLED instead.
Result:
More user-friendly API when ALPN/NPN is not needed by a user.
Motivation:
Improvements were made on the main line to support ALPN and mutual
authentication for TLS. These should be backported.
Modifications:
- Backport commits from the master branch
- f8af84d599
- e74c8edba3
Result:
Support for ALPN and mutual authentication.
