OpenSsl.memoryAddress(...) should use internalNioBuffer(...) if it can't access the memoryAddress (#10818)
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.

Use http in xmlns URIs to make maven release plugin happy again (#10788)
Motivation:

https in xmlns URIs does not work and will let the maven release plugin fail:

Use special exception when failing because the SSLEngine was closed (#10783)
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

Better hash algorithm in FingerprintTrustManagerFactory (#10683)
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.

Enable nohttp check during the build (#10708)
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.

Add null rule check in rules array of RuleBasedIpFilter (#10527)
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.

Fix or suppress LGTM findings (#10689)
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.

Add Close method for closing OutputStream and PcapWriteHandler (#10638)
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.

Use SelfSignedCertificate to fix test-failure related to small key size (#10620)
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)

Only set the keymaterial once and correctly handle errors during keymaterial setting on the client-side as well (#10613)
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

Correctly report back when we fail to select the key material and ens… (#10610)
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

Filter out duplicates before trying to find the alias to use (#10612)
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

Add PcapWriteHandler Support (#10498)
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.

Binary search based IpSubnetFilter (#10492)
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.

Allow to customize how SslMasterKeyHandler is enabled (#10513)
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).

Enable SSL_MODE_ENABLE_FALSE_START if jdkCompatibilityMode is false (#10407)
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

Cleanup Conscrypt initialization (#10466)
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.

- Remove static field which is not needed anymore

Result:

Enable TLS1.3 by default of JDK SSLEngine implementation does by default (#10451)
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.

Make the TLSv1.3 check more robust and not depend on the Java version… (#10409)
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.

Support session cache for client and server when using native SSLEngine implementation (#10331)
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

jdk.tls.client.enableSessionTicketExtension must be respected by OPENSSL and OPENSSL_REFCNT SslProviders (#10401)
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 return NEED_WRAP if we produced some data even if we could not consume any during SSLEngine.wrap(...) (#10396)
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

Modify OpenSSL native library loading to accommodate GraalVM (#10395)
**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.

Correctly include TLS1.3 ciphers in the enabled ciphersuites when using BoringSSL (#10388)
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(...)

Ensure we feed all data to the SSLEngine during handshaking in our tests (#10373)
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.

b559711f3e
Motivation: (#10326)
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.

Fix a test case problem: testSwallowedReadComplete(...) may fail with an AssertionError sometimes. (#10313)
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.

SslHandler#wrap to preserve exception if SSLEngine is closed (#10327)
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.

Dequeue all cached messages and destroy the queue instance after removing the FlowControlHandler from channel pipeline. (#10304)
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.

Do not require BoringSSL for testSessionTicketsWithTLSv12AndNoKey (#10301)
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.

Check if SSL pointer was freed before using it in RefereceCountedOpenSslEngine in all cases (#10299)
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.

Respect jdk.tls.client.enableSessionTicketExtension and jdk.tls.server.enableSessionTicketExtension when using native SSL impl (#10296)
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

Allow to have the session tickets automatically managed by the native… (#10280)
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

Specify algorithm for key pair in self signed certificate to generate EC or RSA based certificate. (#10223)
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.

Add check for DefaultFileRegion to calculate size of msg in AbstractTrafficShapingHandler (#10215)
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.

Release the channel attribute--REOPEN_TASK after removing the TrafficShapingHandler from channel pipeline. (#10177)
Motivation:

The `AbstractTrafficShapingHandler` caches the `ReopenReadTimerTask` instance in the channel attribute. However, if this handler is removed from the channel pipeline, this `ReopenReadTimerTask` instance may not be released.

Modification:

Release the channel attribute `REOPEN_TASK` in `handlerRemoved` method.

Result:

Avoid a channel attribute leak.

Allow Conscrypt to be used on Android (#10182)
**Motivation:**

Following up on https://github.com/netty/netty/issues/10181

I was able to successfully setup a Netty server with TLS on Android, using Conscrypt, with the change proposed here. Conscrypt publishes an [Android specific version](https://github.com/google/conscrypt#android). But the current availability check prevents Netty from using it (the call `PlatformDependent.javaVersion()` returns `6` on Android).

**Modification:**

Check whether the java version is above 8, or if it's running on an Android device, to flag Conscrypt as available (besides the remaining checks).

**Result:**

Netty with TLS runs fine on Android 👍

SslHandler should fail handshake / close promise and notify pipeline on removal (#10161)
Motivation:

If the SslHandler is removed from the pipeline we also need to ensure we fail the handshake / close promise if it was not notified before as otherwise we may never do so.

Modifications:

- Correctly fail promise and notify pipeline if handshake was not done yet when the SslHandler is removed
- Add unit test

Result:

Fix https://github.com/netty/netty/issues/10158

Don't produce multiple calls to exceptionCaught(...) on SSL handshake failure (#10134)
Motivation:

Before release 4.1.23, there was only ONE call to exceptionCaught method when an ssl handshake failure occurs, now we have two when using the JDK provider.

Modifications:

- Ensure we only propagate one exception fi we already failed the handshake and channelInactive(...) produce an exception again
- Add unit test

Result:

Add log level check simply before logging. (#10080)
Motivation:

In general, we will close the debug log in a product environment. However, logging without external level check may still affect performance as varargs will need to allocate an array.

Add SslHandshakeTimeoutException and use it for handshake timeouts (#10062)
Motivation:

Often it is useful to be able to detect different sorts of SSL errors that cause the handshake to fail. To make this easier we should throw and explicit exception type for handshake timeouts.

Modifications:

- Add SslHandshakeTimeoutException (which extends SSLHandshakeException) and use it for handshake timeouts
- Adjust testcases

Result:

Easier to detect that handshake failed because of a timeout

Correctly handle lifecycle of clientHello ByteBuf in SslClientHelloHandler (#10030)
Motivation:

Due incorrectly handling of reference count of the clientHello ByteBuf we may overrelease the buffer. This did show up in the log of a test:

Motivation:

Sometimes it is useful to do something depending on the Ssl ClientHello (like for example select a SslContext to use). At the moment we only allow to hook into the SNI extension but this is not enough.

Modifications:

Add SslClientHelloHandler which allows to hook into ClientHello messages. This class is now also the super class of AbstractSniHandler

Result:

More flexible processing of SSL handshakes

SslHandler.wrap(...) must ensure it not loose the original exception when finishWrap(...) fails (#9974)
Motivation:

When SslHandler.finishWrap throws an exception, ensure that the promise and buf is not reused to avoid throwing IllegalArgumentException or IllegalReferenceCountException which causes the original exception to be lost.

Modification:

The change ensures that the values for the promise and bytebuf are nulled before calling finishWrap so that it will not be called again with the same arguments.

Result:

Fixes #9971 .

384eaf773c Set keystoreType for JdkSslClientContext Keystores (#9965)
Motivation:

In the PR #9003, the issue #8998 was supposedly solved. But actually the fix only made it so the TrustManager can use the specified keystore type instead of also supporting it in the KeyManagerFactory.

In my environment, we are using PKCS#11 Keys which are then rejected by the PKCS#12 keystore. A PKCS#12 keystore is created since the keystoreType was set to null by the code from the mentioned PR.

Modification:

Do not ignore the keystoreType parameter during the creation of the JdkSslClientContext KeyManagerFactory.

Result:

Fixes #8998.

a7de4747d0 Add ByteBufFormat option to LoggingHandler (#9915)
Motivation

LoggingHandler is a very useful tool for debugging and for tracking the
sequence of events in a pipeline. LoggingHandler also includes the
functionality to log a hex dump of all written and received ByteBufs.
This can be useful for small messages, but for large messages, this can
potentially result in extremely large logs. E.g., a 1 MB payload will
result in over a 1 MB log message being recorded. While LoggingHandler
may only be intended for debugging, this can still be too excessive in
some debugging scenarios.

Modifications

* Create a new ByteBufFormat enum that allows users to specify "SIMPLE"
or "HEX_DUMP" logging for ByteBufs.
* For all constructors that currently accept a LogLevel parameter,
create new overloaded constructors that also accept this enum as a
parameter.
* Continue to record hex dumps by default.

Result

Users will be able to opt out of full hex dump recording, if they wish
to.

Reduce allocations in ChunkedWriteHandler when processing the queued … (#9960)
Motivation:

At the moment we create a new ChannelFutureListener per chunk when trying to write these to the underlying transport. This can be optimized by replacing the seperate write and flush call with writeAndFlush and only allocate the listener if the future is not complete yet.

Modifications:

- Replace seperate write and flush calls with writeAndFlush
- Only create listener if needed, otherwise execute directly

Result:

Less allocations

Remove extra field from ChunkedWriteHandler to make it less error-prone (#9958)
Motivation:

At the moment we use an extra field in ChunedWriteHandler to hold the current write. This is not needed and makes sense even more error-prone. We can just peek in the queue.

Modifications:

Use Queue.peek() to keep track of current write

Result:

Less error-prone code

Add ResolveAddressHandler which can be used to resolve addresses on the fly (#9947)
Motivation:

At the moment resolving addresses during connect is done via setting an AddressResolverGroup on the Bootstrap. While this works most of the times as expected sometimes the user want to trigger the connect() from the Channel itself and not via the Bootstrap. For this cases we should provide a ChannelHandler that the user can use that will do the resolution.

Modifications:

Add ResolveAddressHandler and tests

Result:

Be able to resolve addresses without Bootstrap
