Motivation:
af632278d2 introduced a test which only worked on some jvm versions and specific os'es.
Modifications:
Fix test to work on different java versions and os'es
Result:
No flacky test.
Motivation:
We need to ensure we not set duplicated certificates when using OpenSslEngine.
Modifications:
- Skip first cert in chain when set the chain itself and so not send duplicated certificates
- Add interopt unit tests to ensure no duplicates are send.
Result:
No more duplicates.
Motivation:
ReferenceCountedOpenSslEngine depends upon the the SslContext to cleanup JNI resources. If we don't wait until the ReferenceCountedOpenSslEngine is done with cleanup before cleaning up the SslContext we may crash the JVM.
Modifications:
- Wait for the channels to close (and thus the ReferenceCountedOpenSslEngine to be cleaned up) before cleaning up the associated SslContext.
Result:
Cleanup sequencing is correct and no more JVM crash.
Fixes https://github.com/netty/netty/issues/5692
Motivation:
OpenSslEngine and OpenSslContext currently rely on finalizers to ensure that native resources are cleaned up. Finalizers require the GC to do extra work, and this extra work can be avoided if the user instead takes responsibility of releasing the native resources.
Modifications:
- Make a base class for OpenSslENgine and OpenSslContext which does not have a finalizer but instead implements ReferenceCounted. If this engine is inserted into the pipeline it will be released by the SslHandler
- Add a new SslProvider which can be used to enable this new feature
Result:
Users can opt-in to a finalizer free OpenSslEngine and OpenSslContext.
Fixes https://github.com/netty/netty/issues/4958
Motivation:
Unit test for the OpenSslEngine "OpenSslEngine writePlaintextData WANT_READ with no data in BIO buffer" issue.
Modifications:
- Update SslEngine test to include renegotiation
Result:
More test coverage in OpenSslEngine.
Motivation:
These methods were recently deprecated. However, they remained in use in several locations in Netty's codebase.
Modifications:
Netty's code will now access the bootstrap config to get the group or child group.
Result:
No impact on functionality.
Motivation:
At the moment SSLSession.getId() may always return an empty byte array when OpenSSLEngine is used. This is as we not set SSL_OP_NO_TICKET on the SSLContext and so SSL_SESSION_get_id(...) will return an session id with length of 0 if tickets are not used.
Modifications:
- Set SSL_OP_NO_TICKET by default and only clear it if the user requests the usage of session tickets.
- Add unit test
Result:
Ensure consistent behavior between different SSLEngine implementations.
Motivation:
We need to enable SSL_MODE_ACCEPT_MOVING_WRITE_BUFFER when using OpenSslContext as the memory address of the buffer that is passed to OpenSslEngine.wrap(...) may change during calls and retries. This is the case as
if the buffer is a heap-buffer we will need to copy it to a direct buffer to hand it over to the JNI layer. When not enable this mode we may see errors like: 'error:1409F07F:SSL routines:SSL3_WRITE_PENDING: bad write retry'.
Related to https://github.com/netty/netty-tcnative/issues/100.
Modifications:
Explitict set mode to SSL.SSL_MODE_RELEASE_BUFFERS | SSL.SSL_MODE_ACCEPT_MOVING_WRITE_BUFFER . (SSL.SSL_MODE_RELEASE_BUFFERS was used before implicitly).
Result:
No more 'error:1409F07F:SSL routines:SSL3_WRITE_PENDING: bad write retry' possible when writing heap buffers.
Motivation:
Attempts to enable SSL protocols which are currently disabled fail when using the OpenSslEngine. Related to https://github.com/netty/netty/issues/4736
Modifications:
Clear out all options that have disabled SSL protocols before attempting to enable any SSL protocol.
Result:
setEnabledProtocols works as expected.
Motivation:
Currently there are no tests for OpenSSL Engine,
only for JdkSSL engine.
Modifications:
Common methods from `JdkSslEngine` test moved
to `SSLEngineTest`, JdkSslEngine now implements
NPN and ALPN tests.
Result:
OpenSSL Engine is now covered with unit tests.
Motivation:
Use new / non-deprecated APIs for creating SSL Context
in tests, in order to be able to implement OpenSsl
tests with maximum code reuse.
Modifications:
Use `SslContextBuilder.(forServer|forClient)` instead
of deprecated `JdkSslServerContext` constructor.
Use `ApplicationProtocolConfig` instead of Protocol
Negotiator.
Use custom exception type for skipping tests to avoid
swallowing exceptions arising from tests.
Result:
Exceptions from tests aren't swallowed.
Using new APIs allows reusing same test code for
OpenSsl tests.
Motivation:
The SSLSession allows to invalidate a SSLSession and so disallow resume of a session. We should support this for OpenSSLEngine as well.
Modifications:
- Correctly implement SSLSession.isValid() and invalidate() in OpenSSLEngine
- Add unit test.
Result:
Invalidate of SSL sessions is supported when using OpenSSL now.
Motivation:
As a SSL session may be created later at some time we should compute the creation time in a lazy fashion.
Modifications:
- Lazy compute creation time
- Add some unit test
Result:
More correct behavior
Related: #3641 and #3813
Motivation:
When setting up an HTTP/1 or HTTP/2 (or SPDY) pipeline, a user usually
ends up with adding arbitrary set of handlers.
Http2OrHttpChooser and SpdyOrHttpChooser have two abstract methods
(create*Handler()) that expect a user to return a single handler, and
also have add*Handlers() methods that add the handler returned by
create*Handler() to the pipeline as well as the pre-defined set of
handlers.
The problem is, some users (read: I) don't need all of them or the
user wants to add more than one handler. For example, take a look at
io.netty.example.http2.tiles.Http2OrHttpHandler, which works around
this issue by overriding addHttp2Handlers() and making
createHttp2RequestHandler() a no-op.
Modifications:
- Replace add*Handlers() and create*Handler() with configure*()
- Rename getProtocol() to selectProtocol() to make what it does clear
- Provide the default implementation of selectProtocol()
- Remove SelectedProtocol.UNKNOWN and use null instead, because
'UNKNOWN' is not a protocol
- Proper exception handling in the *OrHttpChooser so that the
exception is logged and the connection is closed when failed to
select a protocol
- Make SpdyClient example always use SSL. It was always using SSL
anyway.
- Implement SslHandshakeCompletionEvent.toString() for debuggability
- Remove an orphaned class: JettyNpnSslSession
- Add SslHandler.applicationProtocol() to get the name of the
application protocol
- SSLSession.getProtocol() now returns transport-layer protocol name
only, so that it conforms to its contract.
Result:
- *OrHttpChooser have better API.
- *OrHttpChooser handle protocol selection failure properly.
- SSLSession.getProtocol() now conforms to its contract.
- SpdyClient example works with SpdyServer example out of the box
Motivation:
Currently mutual auth is not supported when using OpenSslEngine.
Modification:
- Add support to OpenSslClientContext
- Correctly throw SSLHandshakeException when an error during handshake is detected
Result:
Mutual auth can be used with OpenSslEngine
