Ensure ByteToMessageDecoder.Cumulator implementations always release in buffer. (#8325)
Motivation:

We need to ensure the Cumulator always releases the input buffer if it can not take over the ownership of it as otherwise it may leak.

Modifications:

- Correctly ensure the buffer is always released.
- Add unit tests.

Result:

Ensure buffer is always released.

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).

Ensure we always encode all data in JdkZlibEncoder. (#8305)
Motivation:

In theory our estimation of the needed buffer could be off and so we need to ensure we grow it if there is no space left.

Modifications:

Ensure we grow the buffer if there is no space left in there but we still have data to deflate.

Result:

Correctly deflate data in all cases.

Cleanup SSL test. (#8301)
Motivation:

I noticed that we had some errors showing up in a test (which did not fail it tho) because we tried to full-fill the promise multiples times.

Modifications:

Use trySuccess(...) as we may produce multiple exceptions.

Result:

Less errors during test-run.

1b6e47ab2b Fix incorrectly encoded empty SOCKS5 address (#8292)
Motivation:

If you encode a SOCKS5 message like new DefaultSocks5CommandResponse(FAILURE, DOMAIN, "", 0)
you correctly get a result of 05010003000000.
But if the bndAddr is null, for example like new DefaultSocks5CommandResponse(FAILURE, DOMAIN)
the encoded result is 0501000301000000 which means the domain name has a length of one and consists of a 0-byte.

Modification:

With this commit it is also correctly encoded as a string of 0 length.

Result:

Correctly encode empty SOCKS5 address

Implemented ExtendedOpenSslSession.getStatusResponses() so it not throws an UnsupportedOperationException. (#8290)
Motivation:

6ed7c6c75d added support for ExtendedOpenSslSession but we did not override getStatusResponses(). This lead to test failures on java9.

Modifications:

Implement ExtendedOpenSslSession.getStatusResponses() so it just returns an empty list.

Result:

Test pass again on Java9.

Only use KeyManagerFactory in SniClientTest when supported by OpenSSL version. (#8289)
Motivation:

6ed7c6c75d added a test which blindly assumed we can use a KeyManagerFactory all the time. This is only true if have OpenSSL 1.0.2 or later, which may not be the case.

Modifications:

Only use KeyManagerFactory in test if the OpenSSL version does support it.

Result:

More robust tests.

Return an ExtendSSLSession whenever possible to allow more strict checking when using OpenSSL (#8281)
Motivation:

When an ExtendedSSLSession is used its possible to do more strict checking of the keys during handshake. We should do this whenever possible.

Modification:

- Return an ExtendedSSLSession when using client-mode and Java7+
- Add unit test
- Simplify unit tests

Result:

Don't cause ClassCastException if registration fails during constructing DnsNameResolver. (#8280)
Motivation:

We should not try to cast the Channel to a DatagramChannel as this will cause a ClassCastException.

Modifications:

- Do not cast
- rethrow from constructor if we detect the registration failed.
- Add unit test.

Result:

Propagate correct exception.

1dff107de1 Don't re-arm timerfd each epoll_wait (#7816)
Motivation:
The Epoll transport checks to see if there are any scheduled tasks
before entering epoll_wait, and resets the timerfd just before.
This causes an extra syscall to timerfd_settime before doing any
actual work.   When scheduled tasks aren't added frequently, or
tasks are added with later deadlines, this is unnecessary.

Modification:
Check the *deadline* of the peeked task in EpollEventLoop, rather
than the *delay*.  If it hasn't changed since last time, don't
re-arm the timer

Result:
About 2us faster on gRPC RTT 50pct latency benchmarks.

2a1596a4e9 Allow to configure socket option SO_BUSY_POLL (#8268)
Motivation:

When using Epoll based transport, allow applications to configure SO_BUSY_POLL socket option:

       SO_BUSY_POLL (since Linux 3.11)
              Sets the approximate time in microseconds to busy poll on a
              blocking receive when there is no data.  Increasing this value
              requires CAP_NET_ADMIN.  The default for this option is con‐
              trolled by the /proc/sys/net/core/busy_read file.

              The value in the /proc/sys/net/core/busy_poll file determines
              how long select(2) and poll(2) will busy poll when they oper‐
              ate on sockets with SO_BUSY_POLL set and no events to report
              are found.

              In both cases, busy polling will only be done when the socket
              last received data from a network device that supports this
              option.

              While busy polling may improve latency of some applications,
              care must be taken when using it since this will increase both
              CPU utilization and power usage.

Modification:

Added SO_BUSY_POLL socket option
Result:

Able to configure SO_BUSY_POLL from Netty

Directly init refCnt to 1 (#8274)
Motivation:

We should just directly init the refCnt to 1 and not use the AtomicIntegerFieldUpdater.

Modifications:

Just assing directly to 1.

Result:

Cleaner code and possible a bit faster as the JVM / JIT may be able to optimize the first store easily.

Use a non-volatile read for ensureAccessible() whenever possible to reduce overhead and allow better inlining. (#8266)
Motiviation:

At the moment whenever ensureAccessible() is called in our ByteBuf implementations (which is basically on each operation) we will do a volatile read. That per-se is not such a bad thing but the problem here is that it will also reduce the the optimizations that the compiler / jit can do. For example as these are volatile it can not eliminate multiple loads of it when inline the methods of ByteBuf which happens quite frequently because most of them a quite small and very hot. That is especially true for all the methods that act on primitives.

It gets even worse as people often call a lot of these after each other in the same method or even use method chaining here.

The idea of the change is basically just ue a non-volatile read for the ensureAccessible() check as its a best-effort implementation to detect acting on already released buffers anyway as even with a volatile read it could happen that the user will release it in another thread before we actual access the buffer after the reference check.

Modifications:

- Try to do a non-volatile read using sun.misc.Unsafe if we can use it.
- Add a benchmark

Result:

Big performance win when multiple ByteBuf methods are called from a method.

With the change:
UnsafeByteBufBenchmark.setGetLongUnsafeByteBuf  thrpt   20  281395842,128 ± 5050792,296  ops/s

Before the change:

Log the correct line-number when using SLF4j with netty if possible. (#8258)
* Log the correct line-number when using SLF4j with netty if possible.

Motivation:

At the moment we do not log the correct line number in many cases as it will log the line number of the logger wrapper itself. Slf4j does have an extra interface that can be used to filter out these nad make it more usable with logging wrappers.

Modifications:

Detect if the returned logger implements LocationAwareLogger and if so make use of its extra methods to be able to log the correct origin of the log request.

Result:

Better logging when using slf4j.

* PemPrivateKey.toPem(...) should throw IllegalArgumentException when PrivateKey which does not support encoding is used.

Motivation:

At the moment when a PrivateKey is used that does not support encoding we throw a NPE when trying to convert the key. We should better throw an IllegalArgumentException with the details about what key we tried to encode.

Modifications:

- Check if PrivateKey.getEncoded() returns null and if so throw an IllegalArgumentException
- Add unit test.

Result:

Better handling of non-supported PrivateKey implementations.

Remove flags when running benchmarks. (#8262)
Motivation:

Some of the flags we used are not supported anymore on more recent JDK versions. We should just remove all of them and only keep what we really need. This may also reflect better what people use in production.

Modifications:

Remove some flags when running the benchmarks.

Allow to generate a jmh uber jar to run benchmarks easily from cmdline with different arguments. (#8264)
Motivation:

It is sometimes useful to be able to run benchmarks easily from the commandline and passs different arguments / options here. We should support this.

Modifications:

Add the benchmark-jar profile which allows to generate such an "uber-jar" that can be used directly to run benchmarks as documented at http://openjdk.java.net/projects/code-tools/jmh/.

Result:

More flexible way to run benchmarks.

NioEventLoop should also use our special SelectionKeySet on Java9 and later. (#8260)
Motivation:

In Java8 and earlier we used reflection to replace the used key set if not otherwise told. This does not work on Java9 and later without special flags as its not possible to call setAccessible(true) on the Field anymore.

Modifications:

- Use Unsafe to instrument the Selector with out special set when sun.misc.Unsafe is present and we are using Java9+.

Result:

NIO transport produce less GC on Java9 and later as well.

PlatformDependent0 should be able to better detect if unaligned access is supported on java9 and later. (#8255)
Motivation:

In Java8 and earlier we used reflection to detect if unaligned access is supported. This fails in Java9 and later as we would need to change the accessible level of the method.
Lucky enough we can use Unsafe directly to read the content of the static field here.

Modifications:

Add special handling for detecting if unaligned access is supported on Java9 and later which does not fail due jigsaw.

Result:

Better and more correct detection on Java9 and later.

c78be33443 Added configurable ByteBuf bounds checking (#7521)
Motivation:

The JVM isn't always able to hoist out/reduce bounds checking (due to ref counting operations etc etc) hence making it configurable could improve performances for most CPU intensive use cases.

Modifications:

Each AbstractByteBuf bounds check has been tested against a new static final configuration property similar to checkAccessible ie io.netty.buffer.bytebuf.checkBounds.

Result:

Any user could disable ByteBuf bounds checking in order to get extra performances.

Do not fail on runtime when an older version of Log4J2 is on the classpath. (#8240)
Motivation:

At the moment we will just assume the correct version of log4j2 is used when we find it on the classpath. This may lead to an AbstractMethodError at runtime. We should not use log4j2 if the version is not correct.

Correctly check if cipher is supported for each SslProvider before trying to run test and fix buffer leaks in test. (#8247)
Motivation:

5aaa16b24c introduced a testcase for specific ciphersuites and checked if these are supported by our native implementation before running it. Unfortunally this is not good enough as even on the JDK it may not be supported on various JDK versions (like Java7). Beside this the test leaked buffers.

Modifications:

- Correctly check if ciphersuite is supported on each SslProvider before trying to run test.
- Fix buffer leaks.

a9863f8128 Add headers to MqttMessage returned by MqttDecoder in case of DecoderException (#8219)
Motivation:
When the MqttDecoder decodes a message larger than the 'maxBytesInMessage' a DecoderException is thrown and a MqttMessage with just the failure cause is returned. Even if I can't handle the message, I might want to send an ACK so that I won't have to worry about it again.

Modification:
The DecoderException is thrown after the variableHeader is decoded. The fixed and variable headers are then added to the MqttMessage along with the failure cause.

Result:
The invalid MqttMessage will have headers if available.

* We should be able to use the ByteBuffer cleaner on java8 (and earlier versions) even if sun.misc.Unsafe is not present.

Motivation:

At the moment we have a hard dependency on sun.misc.Unsafe to use the Cleaner on Java8 and earlier. This is not really needed as we can still use pure reflection if sun.misc.Unsafe is not present.

Modifications:

Refactor Cleaner6 to fallback to pure reflection if sun.misc.Unsafe is not present on system.

Result:

More timely releasing of direct memory on Java8 and earlier when sun.misc.Unsafe is not present.

Modifications:

- Correctly disable usage of sun.misc.Unsafe when -PnoUnsafe is used while running the build
- Correctly increment metric when UnpooledDirectByteBuf is allocated. This was uncovered once -PnoUnsafe usage was fixed.
- Implement fallbacks in all our native transport code for when sun.misc.Unsafe is not present.

Result:

Fixes https://github.com/netty/netty/issues/8229.

5aaa16b24c An unit test to ensure that cipher suites don't break/disappear between releases. (#8225)
Motivation

Ensure classes of cipher suites continue working between releases. Adding just a DHE check for now as it caused #8165 but this test can be expaned to other suites.

Modifications

Adding an unit test that checks for the presence of a cipher suite.

Result

Prevent #8165 from happening in the future.

We should prefer direct buffers if we can access the cleaner even if sun.misc.Unsafe is not present. (#8233)
Motivation:

We should prefer direct buffers whenever we can use the cleaner even if sun.misc.Unsafe is not present.

Modifications:

Correctly prefer direct buffers in all cases.

Result:

More correct code.

CleanerJava9 should be able to do its job even with a SecurityManager installed. (#8204)
Motivation:

CleanerJava9 currently fails whever a SecurityManager is installed. We should make use of AccessController.doPrivileged(...) so the user can give it the correct rights.

Modifications:

Use doPrivileged(...) when needed.

Result:

Fixes https://github.com/netty/netty/issues/8201.

338ef96931 Recycler will produce npe error when multiple recycled at different thread
Motivation:

Recycler may produce a NPE when the same object is recycled multiple times from different threads.

Modifications:

- Check if the id has changed or if the Stack became null and if so throw an IllegalStateException
- Add unit test

Result:

Fixes https://github.com/netty/netty/issues/8220.

Modifications:

Add some more details to the javadocs about the correct replacement.

Result:

Related to https://github.com/netty/netty/issues/8214.
