Motivation:
At the moment we don't support session caching on the client side at all when using the native SSL implementation. We should at least allow to enable it.
Modification:
Allow to enable session cache for client side but disable ti by default due a JDK bug atm.
Result:
Be able to cache sessions on the client side when using native SSL implementation .
Motivation:
In WriteTimeoutHandler we did make the assumption that the executor which is used to schedule the timeout is the same that is backing the write promise. This may not be true which will cause concurrency issues
Modifications:
Ensure we are on the right thread when try to modify the doubly-linked-list and if not schedule it on the right thread.
Result:
Fixes https://github.com/netty/netty/issues/11053
Motivation:
We need to ensure that we call queue.remove() before we cal writeAndFlush() as this operation may cause an event that also touches the queue and remove from it. If we miss to do so we may see NoSuchElementExceptions.
Modifications:
- Call queue.remove() before calling writeAndFlush(...)
- Add unit test
Result:
Fixes https://github.com/netty/netty/issues/11046
Motivation:
The `!fastOpen` part of `active || !fastOpen` is always false.
Modification:
- Remove `!fastOpen` and keep only `active` as a `flushAtEnd` flag for
`startHandshakeProcessing`;
- Update comment;
Result:
Simplified `flushAtEnd` flag computation in `SslHandler#handlerAdded`.
Support TCP Fast Open for clients and make SslHandler take advantage
Motivation:
- TCP Fast Open allow us to send a small amount of data along side the initial SYN packet when establishing a TCP connection.
- The TLS Client Hello packet is small enough to fit in there, and is also idempotent (another requirement for using TCP Fast Open), so if we can save a round-trip when establishing TLS connections when using TFO.
Modification:
- Add support for client-side TCP Fast Open for Epoll, and also lowers the Linux kernel version requirements to 3.6.
- When adding the SslHandler to a pipeline, if TCP Fast Open is enabled for the channel (and the channel is not already active) then start the handshake early by writing it to the outbound buffer.
- An important detail to note here, is that the outbound buffer is not flushed at this point, like it would for normal handshakes. The flushing happens later as part of establishing the TCP connection.
Result:
- It is now possible for clients (on epoll) to open connections with TCP Fast Open.
- The SslHandler automatically detects when this is the case, and now send its Client Hello message as part of the initial data in the TCP Fast Open flow when available, saving a round-trip when establishing TLS connections.

Motivation:
The testGlobalWriteThrottle is flaky and failed our build multiple times now. Lets disable it for now until we had time to investigate
Modifications:
Disable flaky test
Result:
Less failures during build
Motivation:
At the moment we always set SSL_OP_NO_TICKET when building our context. The problem with this is that this also disables resumption for TLSv1.3 in BoringSSL as it only supports stateless resumption for TLSv1.3 which uses tickets.
We should better clear this option when TLSv1.3 is enabled to be able to resume sessions. This is also inline with the OpenJDK which enables this for TLSv1.3 by default as well.
Modifications:
Check for enabled protocols and if TLSv1.3 is set clear SSL_OP_NO_TICKET.
Result:
Be able to resume sessions for TLSv1.3 when using BoringSSL.
Motivation:
File.createTempFile(String, String)` will create a temporary file in the system temporary directory if the 'java.io.tmpdir'. The permissions on that file utilize the umask. In a majority of cases, this means that the file that java creates has the permissions: `-rw-r--r--`, thus, any other local user on that system can read the contents of that file.
This can be a security concern if any sensitive data is stored in this file.
This was reported by Jonathan Leitschuh <jonathan.leitschuh@gmail.com> as a security problem.
Modifications:
Use Files.createTempFile(...) which will use safe-defaults when running on java 7 and later. If running on java 6 there isnt much we can do, which is fair enough as java 6 shouldnt be considered "safe" anyway.
Result:
Create temporary files with sane permissions by default.
Motivation:
Some of the features we want to support can only be supported by some of the SslContext implementations. We should allow to configure these in a consistent way the same way as we do it with Channel / ChannelOption
Modifications:
- Add SslContextOption and add builder methods that take these
- Add OpenSslContextOption and define two options there which are specific to openssl
Result:
More flexible configuration and implementation of SslContext
Motivation:
It was not 100% clear who is responsible calling close() on the InputStream.
Modifications:
Clarify javadocs.
Result:
Related to https://github.com/netty/netty/issues/10974
Co-authored-by: Chris Vest <christianvest_hansen@apple.com>
Motivation:
TLS_FALSE_START slightly changes the "flow" during handshake which may cause suprises for the end-user. We should better disable it by default again and later add a way to enable it for the user.
Modification:
This reverts commit 514d349e1f.
Result:
Restore "old flow" during TLS handshakes.
Motivation:
We didnt correctly filter out TLSv1.3 ciphers when TLSv1.3 is not enabled.
Modifications:
- Filter out ciphers that are not supported due the selected TLS version
- Add unit test
Result:
Fixes https://github.com/netty/netty/issues/10911
Co-authored-by: Bryce Anderson <banderson@twitter.com>
Motivation:
If the given port is already bound, the PcapWriteHandlerTest will sometimes fail.
Modification:
Use a dynamic port using `0`, which is more reliable
Result:
Less Flaky
Motivation:
Creating certificates from a byte[] while lazy parse it is general useful and is also needed by https://github.com/netty/netty-incubator-codec-quic/pull/141
Modifications:
Move classes, rename these and make them public
Result:
Be able to reuse code
Motivation:
We should override the get*ApplicationProtocol() methods in ReferenceCountedOpenSslEngine to make it easier for users to obtain the selected application protocol
Modifications:
Add missing overrides
Result:
Easier for the user to get the selected application protocol (if any)
Motivation:
We should expose some methods as protected to make it easier to write custom SslContext implementations.
This will be reused by the code for https://github.com/netty/netty-incubator-codec-quic/issues/97
Modifications:
- Add protected to some static methods which are useful for sub-classes
- Remove some unused methods
- Move *Wrapper classes to util package and make these public
Result:
Easier to write custom SslContext implementations
Motivation:
We need to ensure we always drain the error stack when a callback throws as otherwise we may pick up the error on a different SSL instance which uses the same thread.
Modifications:
- Correctly drain the error stack if native method throws
- Add a unit test which failed before the change
Result:
Always drain the error stack
Motivation:
When validating PRs we should also at least run one job that uses boringssl
Modifications:
- Add job that uses boringssl
- Cleanup docker compose files
- Fix buffer leak in test
Result:
Also run with boringssl when PRs are validated
Motivation:
When using the JDKs SSLEngineImpl with TLSv1.3 it sometimes returns HandshakeResult.FINISHED multiple times. This can lead to have SslHandshakeCompletionEvents to be fired multiple times.
Modifications:
- Keep track of if we notified before and if so not do so again if we use TLSv1.3
- Add unit test
Result:
Consistent usage of events
Motivation:
We can make use of internalNioBuffer(...) if we cant access the memoryAddress. This at least will reduce the object creations.
Modifications:
Use internalNioBuffer(...) and so reduce the GC
Result:
Less object creation if we can't access the memory address.
Motivation:
https in xmlns URIs does not work and will let the maven release plugin fail:
```

Modifications:
Use http for xmlns
Result:
Be able to use maven release plugin
Motivation:
Sometimes it would be helpful to easily detect if an operation failed due the SSLEngine already be closed.
Modifications:
Add special exception that is used when the engine was closed
Result:
Easier to detect a failure caused by a closed exception
Motivation:
FingerprintTrustManagerFactory can only use SHA-1 that is considered
insecure.
Modifications:
- Updated FingerprintTrustManagerFactory to accept a stronger hash algorithm.
- Deprecated the constructors that still use SHA-1.
- Added a test for FingerprintTrustManagerFactory.
Result:
A user can now configure FingerprintTrustManagerFactory to use a
stronger hash algorithm.
The compiler shows a warning if the code still uses one of the
unsafe constructors.

Motivation:
HTTP is a plaintext protocol which means that someone may be able
to eavesdrop the data. To prevent this, HTTPS should be used whenever
possible. However, maintaining using https:// in all URLs may be
difficult. The nohttp tool can help here. The tool scans all the files
in a repository and reports where http:// is used.
Modifications:
- Added nohttp (via checkstyle) into the build process.
- Suppressed findings for the websites
that don't support HTTPS or that are not reachable
Result:
- Prevent using HTTP in the future.
- Encourage users to use HTTPS when they follow the links they found in
the code.
Motivation:
junit deprecated Assert.assertThat(...)
Modifications:
Use MatcherAssert.assertThat(...) as replacement for deprecated method
Result:
Less deprecation warnings
Motivation:
We can filter out `null` rules while initializing the instance of `RuleBasedIpFilter` so we don't have to keep checking for `null` rules while iterating through `rules` array in `for loop` which is just a waste of CPU cycles.
Modification:
Added `null` rule check inside the constructor.
Result:
No more wasting CPU cycles on check the `null` rule each time in `for loop` and makes the overall operation more faster.
Motivation:
LGTM reports multiple issues. They need to be triaged,
and real ones should be fixed.
Modifications:
- Fixed multiple issues reported by LGTM, such as redundant conditions,
resource leaks, typos, possible integer overflows.
- Suppressed false-positives.
- Added a few testcases.
Result:
Fixed several possible issues, get rid of false alarms in the LGTM report.
Motivation:
Users may want to do special actions when onComplete(...) was called and depend on these once they receive the SniCompletionEvent
Modifications:
Switch order and so call onLookupComplete(...) before we fire the event
Result:
Fixes https://github.com/netty/netty/issues/10655
Motivation:
We should implement the Closeable method to properly close `OutputStream` and `PcapWriteHandler`. So whenever `handlerRemoved(ChannelHandlerContext)` is called or the user wants to stop the Pcap writes into `OutputStream`, we have a proper method to close it otherwise writing data to close `OutputStream` will result in `IOException`.
Modification:
Implemented `Closeable` in `PcapWriteHandler` which calls `PcapWriter#close` and closes `OutputStream` and stops Pcap writes.
Result:
Better handling of Pcap writes.
Motivation:
We need to take the Provider into account as well when trying to detect if TLSv1.3 is used by default / supported
Modifications:
- Change utility method to respect provider as well
- Change testcode
Result:
Less error-prone tests
Motivation:
Some JDKs dissallow the usage of keysizes < 2048, so we should not use such small keysizes in tests.
This showed up on fedora 32:
```
Caused by: java.security.cert.CertPathValidatorException: Algorithm constraints check failed on keysize limits. RSA 1024bit key used with certificate: CN=tlsclient. Usage was tls client
at sun.security.util.DisabledAlgorithmConstraints$KeySizeConstraint.permits(DisabledAlgorithmConstraints.java:817)
at sun.security.util.DisabledAlgorithmConstraints$Constraints.permits(DisabledAlgorithmConstraints.java:419)
at sun.security.util.DisabledAlgorithmConstraints.permits(DisabledAlgorithmConstraints.java:167)
at sun.security.provider.certpath.AlgorithmChecker.check(AlgorithmChecker.java:326)
at sun.security.provider.certpath.PKIXMasterCertPathValidator.validate(PKIXMasterCertPathValidator.java:125)
... 23 more
```
Modifications:
Replace hardcoded keys / certs with SelfSignedCertificate
Result:
No test-failures related to small key sizes anymore.
Motivation:
We should stop as soon as we were able to set the key material on the server side as otherwise we may select keymaterial that "belongs" to a less prefered cipher. Beside this it also is just useless work.
We also need to propagate the exception when it happens during key material selection on the client side so openssl will produce the right alert.
Modifications:
- Stop once we were able to select a key material on the server side
- Ensure we not call choose*Alias more often then needed
- Propagate exceptions during selection of the keymaterial on the client side.
Result:
Less overhead and more correct behaviour
Motivation:
We need to let openssl know that we failed to find the key material so it will produce an alert for the remote peer to consume. Beside this we also need to ensure we wrap(...) until we produced everything as otherwise the remote peer may see partial data when an alert is produced in multiple steps.
Modifications:
- Correctly throw if we could not find the keymaterial
- wrap until we produced everything
- Add test
Result:
Correctly handle the case when key material could not be found
Motivation:
Calling chooseServerAlias(...) may be expensive so we should ensure we not call it multiple times for the same auth methods.
Modifications:
Remove duplicated from authMethods before trying to call chooseServerAlias(...)
Result:
Less performance overhead during key material selection
Motivation:
Following Javadoc standard
Modification:
Change from `@param KeyManager` to `@param keyManager`
Result:
The `@param` matches the actual parameter variable name
Motivation:
Write TCP and UDP packets into Pcap `OutputStream` which helps a lot in debugging.
Modification:
Added TCP and UDP Pcap writer.
Result:
New handler can write packets into an `OutputStream`, e.g. a file that can be opened with Wireshark.
Fixes#10385.
Motivation:
This reverts commit 825916c7f0 as it turns out it introduced a big performance regression.
Modifications:
Revert 825916c7f0
Result:
Performance of TLS is back to normal
Motivation:
`IpSubnetFilter` uses Binary Search for IP Address search which is fast if we have large set of IP addresses to filter.
Modification:
Added `IpSubnetFilter` which takes `IpSubnetFilterRule` for filtering.
Result:
Faster IP address filter.
Motivation:
`RuleBasedIpFilter` had JavaDoc `{@link #channelRejected(ChannelHandlerContext, SocketAddress)}` instead of `{@link AbstractRemoteAddressFilter#channelRejected(ChannelHandlerContext, SocketAddress)}`.
Modification:
Added `AbstractRemoteAddressFilter` reference.
Result:
Fixed JavaDoc error and made documentation more clear.
Motivation:
Right now after a SslMasterKeyHandler is added to the pipeline,
it also needs to be enabled via a system property explicitly. In
some environments where the handler is conditionally added to
the pipeline this is redundant and a bit confusing.
Modifications:
This changeset keeps the default behavior, but allows child
implementations to tweak the way on how it detects that it
should actually handle the event when it is being raised.
Also, removed a private static that is not used in the wireshark
handler.
Result:
Child implementations can be more flexible in deciding when
and how the handler should perform its work (without changing
any of the defaults).
Motivation:
To reduce latency and RTTs we should use TLS False Start when jdkCompatibilityMode is not required and its supported
Modifications:
Use SSL_MODE_ENABLE_FALSE_START when jdkCompatibilityMode is false
Result:
Less RTTs and so lower latency when TLS False Start is supported
Motivation:
How we init our static fields in Conscrypt was kind of error-prone and may even lead to NPE later on when methods were invoked out of order.
Modifications:
- Move all the init code to a static block
- Remove static field which is not needed anymore
Result:
Cleanup and also fixes https://github.com/netty/netty/issues/10413
Motiviation:
When TLSv1.3 was introduced almost 2 years ago, it was decided to disable it by default, even when it's supported by the underlying TLS implementation.
TLSv13 is pretty stable now in Java (out of the box in Java 11, OpenJSSE for Java 8, BoringSSL and OpenSSL) and may be enabled by default.
Modifications:
Ensure TLSv13 is enabled by default when the underyling JDK SSLEngine implementation enables it as well
Result:
TLSv1.3 is now enabled by default, so users don't have to explicitly enable it.

Motivation:
AlgorithmId.sha256WithRSAEncryption_oid was removed in JDK15 and later so we should not depend on it as otherwise we will see compilation errors
Modifications:
Replace AlgorithmId.sha256WithRSAEncryption_oid usage with specify the OID directly
Result:
Compiles on JDK15+
Motivation:
Replace Class.getClassLoader with io.netty.util.internal.PlatformDependent.getClassLoader in Openssl so it also works when a SecurityManager is in place
Modification:
Replace Class.getClassLoader with io.netty.util.internal.PlatformDependent.getClassLoader in Openssl
Result:
No issues when a SecurityManager is in place
Motivation:
TLSv1.3 is not strictly limited to Java11+ anymore as different vendors backported TLSv1.3 to Java8 as well. We should ensure we make the detection of if TLSv1.3 is supported not depend on the Java version that is used.
Modifications:
- Add SslProvider.isTlsv13Supported(...) and use it in tests to detect if we should run tests against TLSv1.3 as well
- Adjust testcase to work on latest JDK 8 release as well
Result:
Correct detection of TLSv1.3 support even if Java version < 11.
Motivation:
At the moment we don't support session caching for client side when using native SSLEngine implementation and our implementation of SSLSessionContext is incomplete.
Modification:
- Consume netty-tcnative changes to be able to cache session in an external cache
- Add and adjust unit tests to test session caching
- Add an in memory session cache that is hooked into native SSLEngine
Result:
Support session caching on the client and server side
Motivation:
jdk.tls.client.enableSessionTicketExtension property must be respect by OPENSSL and OPENSSL_REFCNT SslProvider to ensure a consistent behavior. Due a bug this was not the case and it only worked for OPENSSL_REFCNT but not for OPENSSL.
Modifications:
Move the property check into static method that is used by both
Result:
Correctly respect jdk.tls.client.enableSessionTicketExtension
Motivation:
At the moment we may report BUFFER_OVERFLOW when wrap(...) fails to consume data but still prodce some. This is not correct and we should better report NEED_WRAP as we already have produced some data (for example tickets). This way the user will try again without increasing the buffer size which is more correct and may reduce the number of allocations
Modifications:
Return NEED_WRAP when we produced some data but not consumed any.
Result:
Fix ReferenceCountedOpenSslEngine.wrap(...) state machine
**Motivation:**
We are interested in building Netty libraries with Ahead-of-time compilation with GraalVM. We saw there was [prior work done on this](https://github.com/netty/netty/search?q=graalvm&unscoped_q=graalvm). We want to introduce a change which will unblock GraalVM support for applications using netty and `netty-tcnative`.
This solves the error [that some others encounter](https://github.com/oracle/graal/search?q=UnsatisfiedLinkError+sslOpCipherServerPreference&type=Issues):
```
Exception in thread "main" java.lang.UnsatisfiedLinkError: io.grpc.netty.shaded.io.netty.internal.tcnative.NativeStaticallyReferencedJniMethods.sslOpCipherServerPreference()I [symbol: Java_io_grpc_netty_shaded_io_netty_internal_tcnative_NativeStaticallyReferencedJniMethods_sslOpCipherServerPreference or Java_io_grpc_netty_shaded_io_netty_internal_tcnative_NativeStaticallyReferencedJniMethods_sslOpCipherServerPreference__]
```
**Modification:**
The root cause of the issue is that in the tcnative libraries, the [`SSL.java` class](783a8b6b69/openssl-dynamic/src/main/java/io/netty/internal/tcnative/SSL.java (L67)) references a native call in the static initialization of the class - the method `sslOpCipherServerPreference()` on line 67 is used to initialize the static variable. But you see that `OpenSsl` also uses[ `SSL.class` to check if `netty-tcnative` is on the classpath before loading the native library](cbe238a95b/handler/src/main/java/io/netty/handler/ssl/OpenSsl.java (L123)).
So this is the problem because in ahead-of-time compilation, when it references the SSL class, it will try to load those static initializers and make the native library call, but it cannot do so because the native library has not been loaded yet since the `SSL` class is being referenced to check if the library should be loaded in the first place.
**Solution:** So the proposed solution here is to just choose a different class in the `tcnative` package which does not make a native library call during static initialization. I just chose `SSLContext` if this is OK.
This should have no negative effects other than unblocking the GraalVM use-case.
**Result:**
It fixes the unsatisfied link error. It will fix error for future users; it is a common error people encounter.
Motivation:
There was a new netty-tcnative release which we should use. Beside this the SSLErrorTest was quite fragile and so should be adjusted.
Modifications:
Update netty-tcnative and adjust test
Result:
Use latest netty-tcnative release
Motivation:
BoringSSL behaves differently then OpenSSL and not include any TLS1.3 ciphers in the returned array when calling SSL_get_ciphers(...). This is due the fact that it also not allow to explicit configure which are supported and which not for TLS1.3. To mimic the behaviour expected by the SSLEngine API we should workaround this.
Modifications:
- Add a unit test that verifies enabled protocols / ciphers
- Add special handling for BoringSSL and tls1.3
Result:
Make behaviour consistent
Motivation:
We did not correctly preserve the original cause of the SSLException when all the following are true:
* SSL_read failed
* handshake was finished
* some outbound data was produced durigin SSL_read (for example ssl alert) that needs to be picked up by wrap(...)
Modifications:
Ensure we correctly preserve the original cause of the SSLException and rethrow it once we produced all data via wrap(...)
Result:
Be able to understand why we see an error in all cases
Motivation:
Due a bug in our test we may dropped data on the floor which are generated during handshaking (or slightly after). This could lead to corrupt state in the engine itself and so fail tests. This is especially true for TLS1.3 which generates the sessions on the server after the "actual handshake" is done.
Modifications:
Contine with wrap / unwrap until all data was consumed
Result:
Correctly feed all data to the engine during testing
Motivation:
When ApplicationProtocolNegotiationHandler is in the pipeline we should expect that its handshakeFailure(...) method will be able to completly handle the handshake error. At the moment this is not the case as it only handled SslHandshakeCompletionEvent but not the exceptionCaught(...) that is also triggered in this case
Modifications:
- Call handshakeFailure(...) in exceptionCaught and so fix double notification.
- Add testcases
Result:
Fixes https://github.com/netty/netty/issues/10342
The current FLowControlHandler keeps a flag to track whether a read() call is pending.
This could lead to a scenario where you call read multiple times when the queue is empty,
and when the FlowControlHandler Queue starts getting messages, channelRead will be fired only once,
when we should've fired x many times, once for each time the handlers downstream called read().
Modifications:
Minor change to replace the boolean flag with a counter and adding a unit test for this scenario.
Result:
I used TDD, so I wrote the test, made sure it's failing, then updated the code and re-ran the test
to make sure it's successful after the changes.
Co-authored-by: Kareem Ali <kali@localhost.localdomain>
Motivation:
9b7e091 added a special SSLHandshakeException sub-class to signal handshake timeouts but we missed to update a testcase to directly assert the type of the exception.
Modifications:
Assert directly that SslHandshakeTimeoutException is used
Result:
Test cleanup
Motivation:
It seems that `testSwallowedReadComplete(...)` may fail with an AssertionError sometimes after my tests. The relevant stack trace is as follows:

Obviously the `readerIdleTime` of `IdleStateHandler` and the thread sleep time before `EmbeddedChannel.runPendingTasks` are both 100ms. And if `userEvents.poll()` happened before `userEvents.add(...)` or no `IdleStateEvent` fired at all, this test case would fail.
Modification:
Sleep for a little more time before running all pending tasks in the `EmbeddedChannel`.
Result:
Fix the problem of small probability of failure.
Motivation:
SslHandler currently throws a general SSLException if a wrap attempt
fails due to the SSLEngine being closed. If writes are queued the
failure rational typically requires more investigation to track down the
original failure from a previous event. We may have more informative
rational for the failure and so we should use it.
Modifications:
- SslHandler#wrap to use failure information from the handshake or prior
transport closure if available
Result:
More informative exceptions from SslHandler#wrap if the SSLEngine has
been previously closed.
Motivation:
The `FlowControlHandler` may cache the received messages in a queue in order to do the flow control. However, if this handler is manually removed from pipeline during runtime, those cached messages might not be passed to the next channel handler forever.
Modification:
Dequeue all these cached messages and call `ChannelHandlerContext.fireChannelRead(...)` in `handlerRemoved(...)` method.
Result:
Avoid losing the received messages.
Motivation:
`SslHandlerTest.testSessionTicketsWithTLSv12AndNoKey` does not require
BoringSSL and works with OpenSSL as well.
Modifications:
- Remove assume statement that expected BoringSSL;
Result:
Test works for any implementation of `OPENSSL` provider.
Motivation:
To ensure we not crash in all cases we should better check that the SSL pointer was not freed before using it.
Modifications:
Add missing `isDestroyed()` checks
Result:
Ensure we not crash due usage of freed pointer.
Motivation:
make the existing setter `ReferenceCountedOpenSslContext.setUseTasks` public
Modification:
Added the `public` qualified and removed the comment "for tests only"
Result:
Fixes#10288
Motivation:
We should respect jdk.tls.client.enableSessionTicketExtension and jdk.tls.server.enableSessionTicketExtension when using the native SSL implementation as well to make the usage of it easier and more consistent. These properties were introduced by JDK13:
https://seanjmullan.org/blog/2019/08/05/jdk13
Modifications:
Check if the properties are set to true and if so enable tickets
Result:
Easier to enable tickets and be more consistent
Motivation:
BoringSSL supports to automatically manage the session tickets to be used and so also rotate them etc. This is often prefered by users as it removed some complexity. We should support to make use of this.
Modifications:
- Allow to have setSessionTickets() called without an argument or an empty array
- Add tests
Result:
Easier usage of session tickets
Motivation:
OpenSslSession.getLocalCertificates() and getLocalPrincipal() must return null on client side if mTLS is not used as stated in the API documentation. At the moment this is not always the case
Modifications:
- Ensure we only return non-null if mTLS is used
- Add unit tests
Result:
Follow SSLSession API contract
Motivation:
EC is better than RSA because of the small key size, efficient and secure which makes it perfect for testing purposes.
Modification:
Added support to specify an algorithm (EC or RSA) in constructors for key pair generation. The default key size is 256-bits as promulgated by NSA Suite B.
Result:
Able to generate a self-signed certificate of EC or RSA.
Motivation:
We are far behind with the version of Conscrypt we are using during testing. We should ensure we use the latest.
Modifications:
- Update conscrypt dependency
- Ensure we use conscrypt provider in tests
- Add workarounds for conscrypt bugs in testsuite
Result:
Use latest Conscrypt release
Motivation:
Currently calculateSize method in AbstractTrafficShapingHandler calculates size for object of type ByteBuf or ByteBufHolder. Adding a check for FileRegion, makes it possible to do traffic shaping for FileRegion objects as well
Modification:
Check if object to be sent is of type FileRegion, if yes calculate the size using its count() method.

Motivation:
We need to make some slightly changes to be able to build on Java15 as some previous deprecated methods now throw UnsupportedOperationException
Modifications:
- Add code to handle UnsupportedOperationException
- Revert previous applied workaround for bug that was fixed in Java15
- Add maven profile
Result:
Be able to build with latest Java15 EA release
