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.

Result:

Testsuite pass again on Java7 and others when -Pleak is used.

Log more details when shutdown SSL because of an error. (#8236)
Motivation:

We should log a bit more details about why we shutdown the SSL.

Modifications:

Add the return value of SSL_get_error(...) as well in debug mode.

Result:

More logging to make it easier to understand why an SSL error happened.

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.

Allow to load PrivateKey via OpenSSL Engine (#8200)
Motivation:

OpenSSL itself has an abstraction which allows you to customize some things. For example it is possible to load the PrivateKey from the engine. We should support this.

Modifications:

Add two new static methods to OpenSslX509KeyManagerFactory which allow to create an OpenSslX509KeyManagerFactory that loads its PrivateKey via the OpenSSL Engine directly.

Result:

More flexible usage of OpenSSL possible

We should try to load netty-tcnative before using it in OpenSslCertificateException. (#8202)
Motivation:

In OpenSslCertificateException we should ensure we try to load netty-tcnative before trying to use any class from it as otherwise it may throw an error due missing linking of the native libs.

Modifications:

- Ensure we call OpenSsl.isAvailable() before we try to use netty-tcnative for validation
- Add testcase.

Result:

No more errors causing by not loading native libs before trying to use these.

Rename SslHandler.close(...) to closeOutbound(...) as it is still useful and delegate to the methods. (#8193)
* Rename SslHandler.close(...) to closeOutbound(...) as it is still useful and delegate to the methods.

Motivation:

Sometimes the user may want to send a close_notify without closing the underlying Channel. For this we offered the SslHandler.close(...) methods which were marked as deeprecated. We should offer an way to still do this without the user calling deprecated methods.

See https://stackoverflow.com/questions/51710231/using-nettys-sslhandlerclosechannelhandlercontext-channelpromise/51753742#comment90555949_51753742 .

Modifications:

- Remove deprecation of the SslHandler.close(...) method that exactly allows this and rename these to closeOutbound(...) as this is more clear.
- Add close(...) methods that delegate to these and mark these as deprecated.

Result:

Be able to send close_notify without closing the Channel.

dbc9ec1ab2 Set SNI servernames in OpenSSL engine when created in client mode (#8178)
Motivation:

When using the JDK SSL provider in client mode, the SNI host names (called serverNames in SslEngineImpl) is set to the peerHost (if available) that is used to initialize the SSL Engine:

http://hg.openjdk.java.net/jdk8/jdk8/jdk/file/687fd7c7986d/src/share/classes/sun/security/ssl/SSLEngineImpl.java#l377

This allows one to call SslEngine.getSSLParameters() and inspect what is the SNI name to be sent. The same should be done in the OpenSSL provider as well. Currently even though the the SNI name is sent by the OpenSSL provider during handshake when the peerHost is specified, it is missing from the parameters.

Modification:

Set the sniHostNames field when SNI is to be used. Also verifies the peer is actually a hostname before setting it as the SNI name, which is consistent with JDK SSL provider's behavior.

Result:

SslEngine using the OpenSSL provider created in client mode with peerHost will initialize sniHostNames with the peerHost.

Calling SslEngine.getSSLParameters().getServerNames() will return a list that contains that name.

Fix NPE exception when using invalid cipher during building SslContext. (#8171)
Motivation:

We missed to do a null check before trying to destroy the OpenSslSessionContext, which could lead to a NPE.

Modifications:

Add null check and tests.

Result:

Adjust SSL related tests to be more correct and so pass in the next EA release of java11. (#8162)
Motivation:

In some of our tests we not correctly init the SSLEngine before trying to perform a handshake which can cause an IllegalStateException. While this not happened in previous java releases it does now on Java11 (which is "ok" as its even mentioned in the api docs). Beside this how we selected the ciphersuite to test renegotation was not 100 % safe.

Modifications:

- Correctly init SSLEngine before using it
- Correctly select ciphersuite before testing for renegotation.

Result:

More correct tests and also pass on next java11 EA release.

Allow to validate sni hostname with underscore (#8150)
Motivation:

We should allow to also validate sni hostname which contains for example underscore when using our native SSL impl. The JDK implementation does this as well.

Modifications:

- Construct the SNIHostName via byte[] and not String.
- Add unit test

Result:

Fixes https://github.com/netty/netty/issues/8144.

Fix possible NPE introduced by a137291ad1 when using SslProvider.OPENSSL and init via files or OpenSslX509KeyManagerFactory (#8126)
Motivation:

a137291ad1 introduced a way to get the most speed out of OpenSSL by not only caching keymaterial but pre-compute these. The problem was we missed to check for null before doing an instanceof check and then a cast which could lead to a NPE as we tried to cast null to Exception and throw it.

Modifications:

Add null check and unit test.

Result:

No more NPE when keymaterial was not found for requested alias.

Add OpenSslX509KeyManagerFactory which makes it even easier for peopl… (#8084)
* Add OpenSslX509KeyManagerFactory which makes it even easier for people to get the maximum performance when using OpenSSL / LibreSSL / BoringSSL  with netty.

Motivation:

To make it even easier for people to get the maximum performance when using native SSL we should provide our own KeyManagerFactory implementation that people can just use to configure their key material.

Modifications:

- Add OpenSslX509KeyManagerFactory which users can use for maximum performance with native SSL
- Refactor some internal code to re-use logic and not duplicate it.

Result:

Easier to get the max performance out of native SSL implementation.

Replace toArray(new T[size]) with toArray(new T[0]) to eliminate zero-out and allow the VM to optimize. (#8075)
Motivation:

Using toArray(new T[0]) is usually the faster aproach these days. We should use it.

See also https://shipilev.net/blog/2016/arrays-wisdom-ancients/#_conclusion.

Modifications:

Replace toArray(new T[size]) with toArray(new T[0]).

Result:

Faster code.

Only try to call SSL.setHostnameValidation(...) if needed. (#8074)
Motivation:

As the used OpenSSL version may not support hostname validation we should only really call SSL.setHostNameValidation(...) if we detect that its needed.

Modifications:

Only call SSL.setHostNameValidation if it was disabled before and now it needs to be enabled or if it was enabled before and it should be disabled now.

Result:

Less risk of an exception when using an OpenSSL version that does not support hostname validation.

OpenSSL (and so netty-tcnative) should allow to use custom engine. (#8050)
Motivation:

OpenSSL allows to use a custom engine for its cryptographic operations. We should allow the user to make use of it if needed.

See also: https://www.openssl.org/docs/man1.0.2/crypto/engine.html.

Modifications:

Add new system property which can be used to specify the engine to use (null is the default and will use the build in default impl).

Result:

More flexible way of using OpenSSL.

0337ecdcc8 Allow to cache keymaterial when using OpenSSL
Motiviation:

During profiling it showed that a lot of time during the handshake is spent by parsing the key / chain over and over again. We should cache these parsed structures if possible to reduce the overhead during handshake.

Modification:

- Use new APIs provided by https://github.com/netty/netty-tcnative/pull/360.
- Introduce OpensslStaticX509KeyManagerFactory which allows to wrap another KeyManagerFactory and caches the key material provided by it.

Result:

In benchmarks handshake times have improved by 30 %.

Remove some cipher protocol combos for tests due removal in more recent versions of OpenSSL (#8033)
Motivation:

Some of the cipher protocol combos that were used are no longer included in more recent OpenSSL releases.

Modifications:

Remove some combos that were used for testing.

Result:

Tests also pass in more recent OpenSSL versions (1.1.0+).

3e3e5155b9 Check if Log level is enabled before creating log statements (#8022)
Motivation

There is a cost to concatenating strings and calling methods that will be wasted if the Logger's level is not enabled.

Modifications

Check if Log level is enabled before producing log statement. These are just a few cases found by RegEx'ing in the code.

Result

Tiny bit more efficient code.

Fix race in SslHandlerTest that could lead to NPE. (#7989)
Motivation:

SslHandlerTest tried to get access to the SslHandler in the pipeline via pipeline.get(...) which may return null if the channel was already closed and so the pipeline was teared down.

This showed up in a test run as:

```

Correctly calculate and respect if we can correctly fullfil wrap for alerts. (#7945)
Motivation:

We previously did not correctly take into account when we could not wrap (and so produce) the full SSL record with an alert when the SSLEngine was closed.

There are two problems here:

- If we call wrap(...) with an empty dst buffer after closeOutbound() was called we will not notify the user if we could not store the whole SSLRecord into the dst buffer and so we may produce incomplete SSLRecords

Modifications:

Add unit test which failed before.

Result:

Correctly handle the case when the dst buffer is not big enough and and alert needs to be produced.

Adjust tests to also pass when using BoringSSL (#7946)
Motivation:

Some of the tests failed when using BoringSSL as some protocol / cipher combinations are not supported and it uses a different alert when the cert is not valid yet.

Modification:

- Remove protocol / cipher combos that are not supported by BoringSSL
- Test for different alert when using BoringSSL

Result:

Not test failures when using BoringSSL.

Verify error stack is empty after each operation when using ReferenceCountedOpenSslEngine. (#7943)
Motivation:

https://github.com/netty/netty/pull/7941 proved that its easy to not correctly clear the error stack sometimes. We should do carefully test this.

Modifications:

Correctly detect if protocol is enabled when using netty-tcnative (#7940)
Motivation:

We sometimes did not correctly detect when a protocol is not enabled when using netty-tcnative as we did not take into account when the option flag is 0 (as for example in BoringSSL for SSLv2).

Modifications:

- Correctly take an option flag with 0 into account.
- Add unit tests.

Result:

Correctly clear the error stack in all cases when using ReferenceCountedOpenSslEngine. (#7941)
Motivation:

We missed to correctly clear the error stack in one case when using the ReferenceCountedOpenSslEngine. Because of this it was possible to pick up an error on an unrelated operation.

Modifications:

- Correctly clear the stack
- Add verification of empty error stack to tests.

Result:

Not possible to observe unrelated errors.

8d78893a76 Avoid writing two times the same message in case channelWritabilityChanged event is called during a write.
Motivation:

ChunkedWriteHandler.doFlush is called twice from the same write if the channelWritabilityChanged event is invoked during the write. The buffer is already written so no extra data is sent on the socket but it causes the "promise already done" exception to be thrown.
This error happens only when the message is not ChunkedInput.

Modification:
Clear out the currentWrite reference before the ctx.write call, such that next time when the method is invoked the same object is not used twice.

Result:
