1cc692dd7d Fix incorrect reachability assumption in ResourceLeakDetector (#8410)
Motivation:

trackedObject != null gives no guarantee that trackedObject remains reachable. This may cause problems related to premature finalization: false leak detector warnings.
 
Modifications:

Add private method reachabilityFence0 that works on JDK 8 and can be factored out into PlatformDependent. Later, it can be swapped for the real Reference.reachabilityFence.
 
Result:

No false leak detector warnings in future versions of JDK.

Correctly detect if KeyManagerFactory is supported by OpenSSL even when sun.security.x509.* can not be accessed and bouncycastle is not on the classpath. (#8415)
Motivation:

OpenSsl used SelfSignedCertificate in its static init block to detect if KeyManagerFactory is supported. Unfortunally this only works when either sun.security.x509.* can be accessed or bouncycastle is on the classpath.
We should not depend on either of it.

This came up in https://github.com/netty/netty-tcnative/issues/404#issuecomment-431551890.

Modifications:

Just directly use the bytes to generate the X509Certificate and so not depend on sun.security.x509.* / bouncycastle.

Result:

Correctly be able to detect if KeyManagerFactory can be supported in all cases.

Upgrade commons-compress to 2.0.18 (#8416)
Motivation:

Commons-compress < 2.0.18 has a security flaw so we should upgrade (even if we only use it in tests anyway).

Modifications:

Update to 2.0.18

Result:

Use latest version.

We had put some workaround in our tests due a bug in the Java11 implementation of TLSv1.3. This was now fixes as part of 11.0.1.

See https://bugs.openjdk.java.net/browse/JDK-8211067.

Modifications:

Remove workaround in SSL tests.

Result:

Run all tests with supported TLS version.

Reduce overhead by ByteBufUtil.decodeString(...) which is used by AbstractByteBuf.toString(...) and AbstractByteBuf.getCharSequence(...) (#8388)
Motivation:

Our current implementation that is used for toString(Charset) operations on AbstractByteBuf implementation is quite slow as it does a lot of uncessary memory copies. We should just use new String(...) as it has a lot of optimizations to handle these cases.

Modifications:

Rewrite ByteBufUtil.decodeString(...) to use new String(...)

Result:

Less overhead for toString(Charset) operations.

CompositeByteBuf.decompose(...) does not correctly slice content. (#8403)
Motivation:

CompositeByteBuf.decompose(...) did not correctly slice the content and so produced an incorrect representation of the data.

Modifications:

- Rewrote implementation to fix bug and also improved it to reduce GC
- Add unit tests.

Result:

Fixes https://github.com/netty/netty/issues/8400.

3a4a0432d3 Fix broken testsuite-shading when using with netty-tcnative-boringssl-static (#8404)
Motivation:

2109f14c24 corrected how we run the testsuite with boringssl-static but missed to also adjust the testsuite-shading configuration which lead to test failures.

Modifications:

Correctly compose the native lib name when no classifier is used.

Result:

Testsuite passes again.

a6f807dd68 Fix context and window sizes sides. (#8395)
Motivation:

As mentioned in RFC 7692 :

The "server_no_context_takeover" Extension Parameter should be used on server side for compression and on client side for decompression.

The "client_no_context_takeover" Extension Parameter should be used on client side for compression and on server side for decompression.

Right now, in PerMessageDeflateClientExtensionHandshaker, the decoder uses clientNoContext instead of serverNoContext and the encoder uses serverNoContext instead of clientNoContext.

The same inversion is present in PerMessageDeflateServerExtensionHandshaker: the decoder uses
serverNoContext instead of clientNoContext, while the encoder uses serverNoContext instead of clientNoContext. Besides the context inversion, the sliding window sizes seem to be inversed as well.

Modification:

Inverse clientNoContext with serverNoContext and clientWindowSize with serverWindowSize for both the Decoder and Encoder in PerMessageDeflateServerExtensionHandshaker and PerMessageDeflateClientExtensionHandshaker.

Result:

This fixes the decompression fail in the case that one of the contexts is set and the other one is not.

Allow to use TLSv1.3 with netty-tcnative withe java versions prior to 11. (#8394)
Motivation:

At the moment it's only possible to use TLSv1.3 with netty-tcnative if Java 11 is used. It should be possible to do so even with Java 8, 9 and 10.

Modification:

Add a workaround to be able to use TLSv1.3 also when using Java version prior to Java 11 and the default X509ExtendedTrustManager is used.

Result:

Be able to use TLSv1.3 also with past versions of Java.

Explicit specify java version to use to ensure we rebuild image when java version changes. (#8397)
Motivation:

We should explicit specify the java version to use to ensure docker will rebuild the image once a new java version was released and we specify it. Also we should use openjdk for testing when possible.

Modifications:

- Explicit specify the java versions to use
- Use openjdk when possible.

Result:

Ensure latest java versions are used during testing

Ensure OpenSslEngine will not try to call SSL_free multiple times even when constructor throws. (#8399)
Motivation:

When the constructor of OpenSslEngine threw we could end up to self call SSL_free by ourself and then have the finalizer do the same which may lead to double free-ing and so SIGSEV.

Modifications:

Just call shutdown() when the constructor throws and so ensure SSL_free is guarded correctly in the finalizer.

Result:

No more SIGSEV possible.

Modifications:

Ensure we use empty classifier.

Result:

Add support for TLSv1.3 (#8293)
Motivation:

TLSv1.3 support is included in java11 and is also supported by OpenSSL 1.1.1, so we should support when possible.

Modifications:
- Add support for TLSv1.3 using either the JDK implementation or the native implementation provided by netty-tcnative when compiled against openssl 1.1.1
- Adjust unit tests for semantics provided by TLSv1.3
- Correctly handle custom Provider implementations that not support TLSv1.3

Result:

Be able to use TLSv1.3 with netty.

9eebe7ed74 Add full JdkSslContext public constructor, close #8384 (#8389)
Motivation:

JdkSslContext provides public constructors to wrap an existing `javax.net.ssl.SSLContext`.

Sadly, some options combinations are not possible with the existing constructors, eg:
*  protocols is not exposed and always forced to null, so default protocols are always enforced
* startTls is not exposed and always forced to false

Modification:

Add full constructor that take protocols and startTls parameters.

Result:

It's possible to create a JdkSslContext from an existing SSLContext and still have control over protocols and startTls

- New version contains upgraded version of h2spec

Modifications:
- Bump h2spec-maven-plugin to 0.6
- Remove excluded specs that are no passing
- Add failing spec "half closed (remote): Sends a HEADERS frame" to
exclude list

Result:
Build will fail when non excluded specs fails.

b59336142f deprecate own ConcurrentSet for removal (#8340)
Motivation:

Java since version 6 has the wrapper for the ConcurrentHashMap that could be created via Collections.newSetFromMap(map). So no need to create own ConcurrentSet class. Also, since netty plans to switch to Java 8 soon there is another method for that - ConcurrentHashMap.newKeySet().
For now, marking this class @deprecated would be enough, just to warn users who use netty's ConcurrentSet. After switching to Java 8 ConcurrentSet should be removed and replaced with ConcurrentHashMap.newKeySet().

Modification:

ConcurrentSet deprecated.

Modifications:

Use MACOSX_DEPLOYMENT_TARGET=10.6

Result:

Prevent NPE when attempting to set client key material with no alias (#8378)
Motivation:

It is possible that a client is unable to locate a certificate alias given the list of issuers and key types. In this case the X509KeyManager
will return a null which when past to the OpenSslKeyMaterialProvider implementation may produce a NPE. If no matching alias could be found we should not
call OpenSslKeyMaterialProvider at all which is also consistent what OpenJDK does.

Modifications:

- Add null check before calling OpenSslKeyMaterialProvider
- Add unit test.

Result:

No more NPE caused by passing null as client alias.

Correctly decrement pending bytes when submitting AbstractWriteTask fails. (#8349)
Motivation:

Currently we may end up in the situation that we incremented the pending bytes before submitting the AbstractWriteTask but never decrement these again if the submitting of the task fails. This may result in incorrect watermark handling.

Modifications:

- Correctly decrement pending bytes if subimitting of task fails and also ensure we recycle it correctly.
- Add unit test.

Result:

are added new test case branches to address the increased
complexity of ByteBufInputStream::readLine

Result:

Reduced GC activity if ByteBufInputStream::readLine isn't used

fc28bccdf1 Fix SelectableChannel support in NioEventLoop (#8344)
Motivation:

Unless the 'io.netty.noKeySetOptimization' system property is set,
registering a SelectableChannel instance to a NioEventLoop results
in a ClassCastException:

    io.netty.channel.nio.SelectedSelectionKeySetSelector cannot be cast
        to java.nio.channels.spi.AbstractSelector

Modifications:

Instead of 'selector', pass 'unwrappedSelector' to SelectableChannel.

Result:

It is possible to register a SelectableChannel instance without
setting the 'io.netty.noKeySetOptimization' system property.

3a96e7373b Added option to do busy-wait on epoll (#8267)
Motivation:

Add an option (through a SelectStrategy return code) to have the Netty event loop thread to do busy-wait on the epoll.

The reason for this change is to avoid the context switch cost that comes when the event loop thread is blocked on the epoll_wait() call.

On average, the context switch has a penalty of ~13usec.

This benefits both:

The latency when reading from a socket
Scheduling tasks to be executed on the event loop thread.
The tradeoff, when enabling this feature, is that the event loop thread will be using 100% cpu, even when inactive.

Modification:

Added SelectStrategy option to return BUSY_WAIT
Epoll loop will do a epoll_wait() with no timeout
Use pause instruction to hint to processor that we're in a busy loop
Result:

When enabled, minimizes impact of context switch in the critical path

When writing an HTTP/2 HEADERS with END_STREAM=1, the application expects
the stream to be closed afterward. However, the write can fail locally
due to HPACK encoder and similar. When that happens we need to make sure
to issue a RST_STREAM otherwise the stream can be closed locally but
orphaned remotely. The RST_STREAM is typically handled by
Http2ConnectionHandler.onStreamError, which will only send a RST_STREAM
if that stream still exists locally.

There are two possible flows for trailers, one handled immediately and
one going through the flow controller. Previously they behaved
differently, with the immedate code calling the error handler after
closing the stream. The immediate code also used a listener for calling
closeStreamLocal while the flow controlled code did so immediately after
the write.

The two code paths also differed in their VoidChannelPromise handling,
but both were broken. The immediate code path called unvoid() only if
END_STREAM=1, however it could always potentially add a listener via
notifyLifecycleManagerOnError(). And the flow controlled code path
unvoided incorrectly, changing the promise completion behavior. It also
passed the wrong promise to closeStreamLocal() in FlowControlledBase.

Modifications:

Move closeStreamLocal handling after calls to onError. This is the
primary change.

Now call closeStreamLocal immediately instead of when the future
completes. This is the more likely correct behavior as it matches that
of DATA frames.

Fix all the VoidChannelPromise handling.

Result:

Http2ConnectionHandler.onStreamError sees the same state as the remote
and issues a RST_STREAM, properly cleaning up the stream.

6138541033 Avoid repeating the same field and hiding it (#8335)
Motivation

The EpollChannelConfig (same for KQueues) and its subclasses repeatetly declare their own channel field which leads to a 3x repetition for each config instance. Given the fields are protected or package-private it's exposing the code code to "field hiding" bugs.

Modifications

Use the the existing protected channel field from the DefaultChannelConfig class and simply cast it when needed.

Result

Fixes #8331

Ensure X509KeyManager methods are called on the correct time when using server-side and support more methods of ExtendedSSLSession. (#8283)
Motivation:

Before when on server-side we just called the X509KeyManager methods when handshake() was called the first time which is not quite correct as we may not have received the full SSL hello / handshake and so could not extra for example the SNI hostname that was requested.
OpenSSL exposes the SSL_CTX_set_cert_cb function which allows to set a callback which is executed at the correct moment, so we should use it. This also allows us to support more methods of ExtendedSSLSession easily.

Modifications:

- Make use of new methods exposed by netty-tcnative since https://github.com/netty/netty-tcnative/pull/388 to ensure we select the key material at the correct time.
- Implement more methods of ExtendedOpenSslSession
- Add unit tests to ensure we are able to retrieve various things on server-side in the X509KeyManager and so verify it is called at the correct time.
- Simplify code by using new netty-tcnative methods.

Result:

More correct implementation for server-side usage and more complete implemented of ExtendedSSLSession.

Check if hostname validation is supported before trying to use in test. (#8333)
Motivation:

a208f6dc7c added a testcase which uses hostname validation which may not be supported by OpenSSL depending on the version that is used. We should check first before we try to use it.

Modifications:

Add assumeTrue(...) check to ensure hostname validation is supported before trying to run the test.

Result:

No more test-failures on OpenSSL versions < 1.0.2.

Do the same extended checks as the JDK when a X509TrustManager is used with the OpenSSL provider. (#8307)
Motivation:

When a X509TrustManager is used while configure the SslContext the JDK automatically does some extra checks during validation of provided certs by the remote peer. We should do the same when our native implementation is used.

Modification:

- Automatically wrap a X509TrustManager and so do the same validations as the JDK does.
- Add unit tests.

Result:

More consistent behaviour. Fixes https://github.com/netty/netty/issues/6664.

Use AuthoritativeDnsServerCache for creating the new redirect stream. (#8316)
* Use AuthoritativeDnsServerCache for creating the new redirect stream.

Motivation:

At the moment if a user wants to provide custom sorting of the nameservers used for redirects it needs to be implemented in two places. This is more complicated as it needs to be.

Modifications:

- Just delegate to the AuthoritativeDnsServerCache always as we fill it before we call newRedirectDnsServerStream anyway.

Result:

Easier way for the user to implement custom sorting.

Add cache for CNAME mappings resolved during lookup of DNS entries. (#8314)
* Add cache for CNAME mappings resolved during lookup of DNS entries.

Motivation:

If the CNAMEd hostname is backed by load balancing component, typically the final A or AAAA DNS records have small TTL. However, the CNAME record itself is setup with longer TTL.

For example:
* x.netty.io could be CNAMEd to y.netty.io with TTL of 5 min
* A / AAAA records for y.netty.io has a TTL of 0.5 min

In current Netty implementation, original hostname is saved in resolved cached with the TTL of final A / AAAA records. When that cache entry expires, Netty recursive resolver sends at least two queries — 1st one to be resolved as CNAME record and the 2nd one to resolve the hostname in CNAME record.
If CNAME record was cached, only the 2nd query would be needed most of the time. 1st query would be needed less frequently.

Modifications:

Add a new CnameCache that will be used to cache CNAMEs and so may reduce queries.

Result:

Less queries needed when CNAME is used.

ba594bcf4a Fixed illegal reflective access by not relying on a sun.net.dns class. (#8318) (#8319)
Motivation

Applications should not depend on internal packages with Java 9 and later. This cause a warning now, but will break in future versions of Java.

Modification

This change adds methods to UnixResolverDnsServerAddressStreamProvider (following after #6844) that parse /etc/resolv.conf for domain and search entries. Then DnsNameResolver does not need to rely on sun.net.dns.ResolverConfiguration to do this.

Result

Fixes #8318. Furthermore, at least in my testing with Java 11, this also makes multiple search entries work properly (previously I was only getting the first entry).
