d495792c48 Allow to wrap another SslContext implementation and do extra init steps on the SSLEngine.
Motivation:

Sometimes its needed to customize the SSLEngine (like setting protocols etc). For this it would be useful if the user could wrap an SslContext and do init steps on the SSLEngine.

Modifications:

Add new SslContext implementation which can wrap another one and allow to customize the SSLEngine

Result:

More flexible usage of SslContext.

7c1374dd54 OpenSslEngine.getSupportedCipherSuites() must return java names as well.
Motivation:

At the moment OpenSslEngine.getSupportedCipherSuites() only return the original openssl cipher names and not the java names. We need also include the java names.

Modifications:

Correctly return the java names as well.

Result:

Correct implementation of OpenSslEngine.getSupportedCipherSuites()

d964bf6f18 Remove usages of deprecated methods group() and childGroup().
Motivation:

These methods were recently deprecated. However, they remained in use in several locations in Netty's codebase.

Modifications:

Netty's code will now access the bootstrap config to get the group or child group.

Result:

No impact on functionality.

9687d77b5a Move validation of arguments out of synchronized block
Motivation:

There is no need already use synchronized when validate the args of the methods.

Modifications:

First validate arguments and then use synchronized

Result:

Less code executed in synchronized block.

e845670043 Set some StackTraceElement on pre-instantiated static exceptions
Motivation:

We use pre-instantiated exceptions in various places for performance reasons. These exceptions don't include a stacktrace which makes it hard to know where the exception was thrown. This is especially true as we use the same exception type (for example ChannelClosedException) in different places. Setting some StackTraceElements will provide more context as to where these exceptions original and make debugging easier.

Modifications:

Set a generated StackTraceElement on these pre-instantiated exceptions which at least contains the origin class and method name. The filename and linenumber are specified as unkown (as stated in the javadocs of StackTraceElement).

Result:

Easier to find the origin of a pre-instantiated exception.

f2efd68c39 Correctly support SSLSession.getId() when using OpenSslEngine
Motivation:

At the moment SSLSession.getId() may always return an empty byte array when OpenSSLEngine is used. This is as we not set SSL_OP_NO_TICKET on the SSLContext and so SSL_SESSION_get_id(...) will return an session id with length of 0 if tickets are not used.

Modifications:

- Set SSL_OP_NO_TICKET by default and only clear it if the user requests the usage of session tickets.
- Add unit test

Result:

Ensure consistent behavior between different SSLEngine implementations.

e4d21abfc1 Add support for SSLParameters.setCipherSuiteOrder() when using Java8+
Motivation:

When using java8+ we should support SSLParameters.setCipherSuiteOrder()

Modifications:

Add support of SLParameters.setCipherSuiteOrder() by using reflection, so we can compile with java7 but still support it.

Result:

Users that use java8+ can use SSLParameters.setCipherSuiteOrder()

e14a385a88 Add support for SNIHostName when using Java8+
Motivation:

Java8 added support for using SNIHostName with SSLParameters. We currently ignore it in OpenSslEngine.

Modifications:

Use reflection to support SNIHostName.

Result:

People using Java8 can use SNIHostName even when OpenSslEngine is used.

87d9ecc2c9 Correctly skip OpenSsl* tests if OpenSsl.isAvailable() is false.
Motivation:

We missed to skip some tests for OpenSsl when OpenSsl.isAvailable() is false.

Modifications:

- Correctly skip tests when OpenSsl.isAvailable() is false.
- Simplify some code by using @BeforeClass.

Result:

Be able to compile netty even when OpenSsl is not present on the system.

65d1fb474d Guard against possible segfault when OpenSslContext is gc'ed and user still hold reference to OpenSslSessionContext / OpenSslSessionStats
Motivation:

When the OpenSslContext is gc'ed and the user still hold a reference to OpenSslSessionContext / OpenSslSessionStats it is possible to produce a segfault when calling
a method on any of these that tries to pass down the ctx pointer to the native methods. This is because the OpenSslContext finalizer will free the native pointer.

Modifications:

Change OpenSslSessionContext / OpenSslSessionContext to store a reference to OpenSslContext and so prevent the GC to collect it as long as the user has a reference to OpenSslSessionContext / OpenSslSessionContext.

Result:

No more sefault possible.

fe569ea7a3 Fix for a newly intrduced bug in #5377
Motivation

This bug was introduced with #5377 and affects only users who'd like to share/cache/re-use `PemPrivateKey` and `PemX509Certificate` instances.

Modifications

Use `ByteBuf#writeBytes(src, readerIndex, length)` so that the src's readerIndex doesn't change and can consequently be used more than once.

Result

It's possible to share/cache/re-use `PemPrivateKey` and `PemX509Certificate` instances as long as their refCnt remains >= 1.

a7496ed83d FlowControlHandlerTest synchronization issues
Motivation:
2b65258568 only partially addressed the synchronization issues that are present in FlowControlHandlerTest. A few tests are attempting to validate state changes made across an EventLoop thread and the JUnit thread but are not properly synchronized.

Modifications:
- Ensure that conditions which verify expectations set in another thread have synchronization gates to ensure the event has actually occurred.
- Remove the message counter verification in favor of using individual CountDownLatch objects

Result:
FLowControlHanderTest has less race conditions which may lead to test failures.

cc580e3ba1 Let OpenSslContext take pre-encoded pkcs#8 private key/cert bytes
Motivation

OpenSslContext is expecting Java's PrivateKey and X509Certificate objects as input
(for JdkSslContext API compatibility reasons) but doesn't really use them beyond
turning them into PEM/PKCS#8 strings.

This conversion can be entirely skipped if the user can pass in private keys and
certificates in a format that Netty's OpenSSL code can digest.

Modifications

Two new classes have been added that act as a wrapper around the pre-encoded byte[]
and also retain API compatibility to JdkSslContext.

Result

It's possible to pass PEM encoded bytes straight into OpenSSL without having to
parse them (e.g. File to Java's PrivateKey) and then encode them (i.e. PrivateKey
into PEM/PKCS#8).

File pemPrivateKeyFile;
byte[] pemBytes = readBytes(pemPrivateKeyFile);
PemPrivateKey pemPrivateKey = PemPrivateKey.valueOf(pemBytes);

c3abb9146e Use shaded dependency on JCTools instead of copy and paste
Motivation:
JCTools supports both non-unsafe, unsafe versions of queues and JDK6 which allows us to shade the library in netty-common allowing it to stay "zero dependency".

Modifications:
- Remove copy paste JCTools code and shade the library (dependencies that are shaded should be removed from the <dependencies> section of the generated POM).
- Remove usage of OneTimeTask and remove it all together.

Result:
Less code to maintain and easier to update JCTools and less GC pressure as the queue implementation nt creates so much garbage

88dbd96376 [#5372] Ensure OpenSslClientContext / OpenSslServerContext can be garbage collected
Motivation:

OpenSslClientContext / OpenSslServerContext can never be garbage collected as both are part of a reference to a callback that is stored as global reference in jni code.

Modifications:

Ensure the callbacks are static and so not hold the reference.

Result:

No more leak due not collectable OpenSslClientContext / OpenSslServerContext

783567420f OpenSslEngine encrypt more data per wrap call
Motivation:
OpenSslEngine.wrap will only encrypt at most 1 buffer per call. We may be able to encrypt multiple buffers per call.

Modifications:
- OpensslEngine.wrap should continue encrypting data until there is an error, no more data, or until the destination buffer would be overflowed.

Result:
More encryption is done per OpenSslEngine.wrap call

9e2c400f89 OpenSslEngine writePlaintextData WANT_READ with no data in BIO buffer
Motivation:
CVE-2016-4970

OpenSslEngine.wrap calls SSL_write which may return SSL_ERROR_WANT_READ, and if in this condition there is nothing to read from the BIO the OpenSslEngine and SslHandler will enter an infinite loop.

Modifications:
- Use the error code provided by OpenSSL and go back to the EventLoop selector to detect if the socket is closed

Result:
OpenSslEngine correctly handles the return codes from OpenSSL and does not enter an infinite loop.

f7cf00cb5f OpenSslEngine remove unecessary rejectRemoteInitiatedRenegation call
Motivation:
OpenSslEngine calls rejectRemoteInitiatedRenegation in a scenario where the number of handshakes has not been observed to change. The number of handshakes has only been observed to change after readPlaintextData is called.

Modifications:
- Remove the call to rejectRemoteInitiatedRenegation before calls to readPlaintextData

Result:
Less code.

528b83e277 Set the session id context properly to make client authentication work with open ssl provider.
Motivation:

When netty is used with open ssl provider and client authentication the following errors can occur:
error:140D9115:SSL routines:ssl_get_prev_session:session id context uninitialized
error:140A1175:SSL routines:ssl_bytes_to_cipher_list:inappropriate fallback
error:140760FC:SSL routines:SSL23_GET_CLIENT_HELLO:unknown protocol

Modifications:

Set the session id context in OpenSslServerContext so that sessions which use client authentication
which are cached have the same context id value.

Result:

Client authentication now works with open ssl provider.

f11a35af32 Replace DomainMappingBuilder with DomainNameMappingBuilder
Motivation:

DomainMappingBuilder should have been named as DomainNameMappingBuilder
because it builds a DomainNameMapping.

Modifications:

- Add DomainNameMappingBuilder that does the same job with
  DomainMappingBuilder
- Deprecate DomainMappingBuilder and delegate its logic to
  DomainNameMappingBuilder
- Remove the references to the deprecated methods and classes related
  with domain name mapping
- Miscellaneous:
  - Fix Javadoc of DomainNameMapping.asMap()
  - Pre-create the unmodifiable map in DomainNameMapping

Result:

- Consistent naming
- Less use of deprecated API

3a9f472161 Make retained derived buffers recyclable
Related: #4333 #4421 #5128

Motivation:

slice(), duplicate() and readSlice() currently create a non-recyclable
derived buffer instance. Under heavy load, an application that creates a
lot of derived buffers can put the garbage collector under pressure.

Modifications:

- Add the following methods which creates a non-recyclable derived buffer
  - retainedSlice()
  - retainedDuplicate()
  - readRetainedSlice()
- Add the new recyclable derived buffer implementations, which has its
  own reference count value
- Add ByteBufHolder.retainedDuplicate()
- Add ByteBufHolder.replace(ByteBuf) so that..
  - a user can replace the content of the holder in a consistent way
  - copy/duplicate/retainedDuplicate() can delegate the holder
    construction to replace(ByteBuf)
- Use retainedDuplicate() and retainedSlice() wherever possible
- Miscellaneous:
  - Rename DuplicateByteBufTest to DuplicatedByteBufTest (missing 'D')
  - Make ReplayingDecoderByteBuf.reject() return an exception instead of
    throwing it so that its callers don't need to add dummy return
    statement

Result:

Derived buffers are now recycled when created via retainedSlice() and
retainedDuplicate() and derived from a pooled buffer

89eae94542 Allow to extend IdleStateHandler and so provide more details for IdleStateEvents
Motivation:

Sometimes it is useful to include more details in the IdleStateEvents that are produced by the IdleStateHandler. For this users should be able to create their own IdleStateEvents that encapsulate more informations.

Modifications:

- Make IdleStateEvent constructor protected and the class non-final
- Add protected method to IdleStateHandler that users can override and so create their own IdleStateEvents.

Result:

More flexible and customizable IdleStateEvents / IdleStateHandler

b39c53ce17 [#5218] Zero out private key copied to ByteBuf before release.
Motivation:

We should zero-out the private key as soon as possible when we not need it anymore.

Modifications:

Result:

Limit the time the private key resist in memory.

2b65258568 FlowControlHandlerTest invalid condition
Motivation:
FlowControlHandlerTest attempts to validate the expected contents of the underlying queue in FlowControlHandler. However the condition which triggers the check is too early and the queue contents may not yet contain all expected objects. For example a CountDownLatch is counted down in a handler's channelRead which is  after the FlowControlHandler in the pipeline. At this point if there is a thread context switch the queue may not yet contain all the expected objects and checking the queue contents is not valid.

Modifications:
- Remove checking the queues contents in FLowControlHandlerTest and instead only check the empty condition at the end of the tests

Result:
FlowControlHandlerTest won't fail due to invalid checks of the contents of the queue.

9b9819c178 Rewrite misleading Note in FingerprintTrustManagerFactory javadoc
Motivation:

The current note reads as if this class is dangerous and advises the reader to "understand what this class does".

Modifications:

Rewrite the Javadoc note to describe what fingerprint checks are and what problems remain.

Result:

Clearer description which no longer causes the impression this class is dangerous.

6b427aaee5 Improve client SNI in testSniWithApnHandler
Motivations
The test SniHandlerTest#testSniWithApnHandler() does not actually
involve SNI: given the client setup, the ClientHello in the form of hex
strings is not actually written to the wire, so the server never receives that.
We may need to write in somewhere else (e.g., channelActive()) instead of in
initChannel() in order for the hex strings to reach the server. So here
what's actually going on is an ordinary TLS C/S communication without SNI.

Modifications
The client part is modified to enable SNI by using an SslHandler with an
SSLEngine created by io.netty.handler.ssl.SslContext#newEngine(), where
the server hostname is specified. Also, more clauses are added to verify that
the SNI is indeed successful.

Results
Now the test verifies that both SNI and APN actually happen and succeed.

5eb0127c2a A new ChannelHandler that allows the user to control the flow of messages if upstream handlers emit more than one event for each read()
Motivation:

Some handlers such as HttpObjectDecoder can emit more than one event per read()
which leads to problems in downstream handlers that expect only one event and hope
that ChannelConfig#setAutoRead(false) prevents further events being sent while they're
processing the one they've just received.

Modifications:

A new handler called FlowControlHandler that feeds off read() and isAutoRead() and acts
as a holding buffer if auto reading gets turned off and more events arrive while auto reading
is off.

Result:

Fixes issues such as #4895.

379ad2c02e Support preloading of tcnative share lib
Motivation:

9498d1a9b3 Allow to create a JdkSslContext from an existing JDK SSLContext. Related to [#5095] and [#4929]
Motivation:

Sometimes a user only has access to a preconfigured SSLContext but still would like to use our ssl sub-system. For this situations it would be very useful if the user could create a JdkSslContext instance from an existing SSLContext.

Modifications:

- Create new public constructors in JdkSslContext which allow to wrap an existing SSLContext and make the class non-abstract
- Mark JdkSslServerContext and JdkSslClientContext as deprecated as the user should not directly use these.

Result:

It's now possible to create an JdkSslContext from an existing SSLContext.

8033faa03b fcbeebf6df unit test bug
Motivation:
fcbeebf6df introduced a unit test to verify ApplicationProtocolNegotiationHandler is compatible with SniHandler. However only the server attempts ALPN and verifies that it completes and the client doesn't verify the handshake is completed. This can lead to the client side SSL engine to prematurely close and throw an exception.

Modifications:
- The client should wait for the SSL handshake and ALPN to complete before the test exits.

Result:
SniHandlerTest.testSniWithApnHandler is more reliable.
2016-04-06 00:11:10 -07:00

fcbeebf6df ApplicationProtocolNegotiationHandler doesn't work with SniHandler
Motivation:
ApplicationProtocolNegotiationHandler attempts to get a reference to an SslHandler in handlerAdded, but when SNI is in use the actual SslHandler will be added to the pipeline dynamically at some later time. When the handshake completes ApplicationProtocolNegotiationHandler throws an IllegalStateException because its reference to SslHandler is null.

Modifications:
- Instead of saving a reference to SslHandler in handlerAdded just search the pipeline when the SslHandler is needed

Result:
ApplicationProtocolNegotiationHandler support SniHandler.

84bbbf7e09 Read if needed on NEED_UNWRAP
Motivation:

There are some use cases when a client may only be willing to read from a channel once
its previous write is finished (eg: serial dispatchers in Finagle). In this case, a
connection with SslHandler installed and ctx.channel().config().isAutoRead() == false
will stall in 100% of cases no matter what order of "channel active", "write", "flush"
events was.

The use case is following (how Finagle serial dispatchers work):

1. Client writeAndFlushes and waits on a write-promise to perform read() once it's satisfied.
2. A write-promise will only be satisfied once SslHandler finishes with handshaking and
   sends the unencrypted queued message.
3. The handshaking process itself requires a number of read()s done by a client but the
   SslHandler doesn't request them explicitly assuming that either auto-read is enabled
   or client requested at least one read() already.
4. At this point a client will stall with NEED_UNWRAP status returned from underlying engine.

Modifiations:

Always request a read() on NEED_UNWRAP returned from engine if

a) it's handshaking and
b) auto read is disabled and
c) it wasn't requested already.

Result:

SslHandler is now completely tolerant of whether or not auto-read is enabled and client
is explicitly reading a channel.

f0f014d0c7 [#4637] More helpful exception message when a non PKCS#8 key is used.
Motivation:

We should throw a more helpful exception when a non PKCS#8 key is used by the user.

Change exception message to give a hint what is wrong.

Result:

Easier for user to understand whats wrong with their used key.

9ebb4b7164 Using distinct aliases when building the trust manager factory, and renamed trustCertChain into trustCertCollection.
Motivation:

SSLContext.buildTrustManagerFactory(...) builds a KeyStore to
initialize the TrustManagerFactory from an array of X509Certificates,
assuming that array is a chain and that each certificate will have a
unique Subject Distinguised Name.
However, the collection of certificates used as trust anchors is generally
not a chain (it is an unordered collection), and it is legitimate for it
to contain multiple certificates with the same Subject DN.
The existing code uses the Subject DN as the alias name when filling in
the `KeyStore`, thereby overwriting other certificates with the same
Subject DN in this collection, so some certificates may be discarded.
In addition, the code related to building trust managers can take an array of
X509Certificate instances to use as trust anchors. The variable name is
usually trustCertChain, and the documentation refers to them as a "chain".
However, while it makes sense to talk about a "chain" from a keymanager
point of view, these certificates are just an unordered collection in a
trust manager. (There is no chaining requirement, having the Subject DN
matching its predecessor's Issuer DN.)
This can create confusion to for users not used with PKI concepts.

Modifications:

SSLContext.buildTrustManagerFactory(...) now uses a distinct alias for each
array (simply using a counter, since this name is never used for reference
later). This patch also includes a unit test with CA certificates using the
same Subject DN.
Also renamed trustCertChain into trustCertCollection, and changed the
references to "chain" in the Javadoc.

Result:

Each loaded certificate now has a unique identifier when loaded, so it is
now possible to use multiple certificates with the same Subject DN as
trust anchors.
Hopefully, renaming the parameter should also reduce confusion around PKI
concepts.

9330631097 Ensure all pending SSL data is written before closing channel during handshake error.
Motivation:

We need to ensure we call ctx.flush() before closing the actual channel when an handshake failure took place. If we miss to do so we may not send all pending data to the remote peer which also include SSL alerts.

Modifications:

Ensure we call ctx.flush() before ctx.close() on a handshake error.

Result:

All pending data (including SSL alerts) are written to the remote peer on a handshake error.

ebfb2832b2 Throw exception if KeyManagerFactory is used with OpenSslClientContext
Motivation:

We currently not supported using KeyManagerFactory with OpenSslClientContext and so should throw an exception if the user tries to do so. This will at least not give suprising and hard to debug problems later.

Modifications:

Throw exception if a user tries to construct a OpenSslClientContext with a KeyManagerFactory

Result:

Fail fast if the user tries to use something that is not supported.

Modifications:

Move all checks inside of the try block.

Motivation:

A user may use a private key which is encrypted with an empty password. Because of this we should only handle a null password in a special way.

- Make OpenSsl*Context implementions consistent in terms of initialization in the constructor.

Result:

Correctly support private key that is encrypted with empty password.

6e9d2bf13c Correctly set the alert type depending of the CertificateException
Motivation:

Depending on the actual CertificateException we should set the correct alert type so it will be sent back to the remote peer and so make it easier for them to fix it.

Modification:

Correctly set the alert and not always just use a general alert.

Result:

It's easier for the remote peer to fix the problems.

- Skip renegotiate tests if boringssl is used.

Result:

Use newest version of netty-tcnative and be able to build if boringssl is used.

61f812ea2a Allow InputStreams for key/trust managers in SslContextBuilder
Motivation:

Sometimes it's easier to get keys/certificates as `InputStream`s than it is to
get an actual `File`. This is especially true when operating in a container
environment and `getResourceAsInputStream` is the best way to load resources
packaged with an application.

Modifications:

- Add read-from-`InputStream` methods to `PemReader`
- Allow `SslContext` to get keys/certificates from `InputStreams`
- Add `InputStream`-based setters for key/trust managers to `SslContextBuilder`

Result:

Callers may pass an `InputStream` instead of a `File` to `SslContextBuilder`.

d9f938ca03 [#4828] OpenSslContext throws UnsupportedOperationException when Unsafe not available
Motivation:

OpenSslContext constructor fails with a UnsupportedOperationException if Unsafe is not present on the system.

Modifications:

Make OpenSslContext work also when Unsafe is not present by fallback to using JNI to get the memory address.

Result:

Using OpenSslContext also works on systems without Unsafe.

eb1d9da76c Enable SSL_MODE_ACCEPT_MOVING_WRITE_BUFFER when using OpenSslContext
Motivation:

We need to enable SSL_MODE_ACCEPT_MOVING_WRITE_BUFFER when using OpenSslContext as the memory address of the buffer that is passed to OpenSslEngine.wrap(...) may change during calls and retries. This is the case as
if the buffer is a heap-buffer we will need to copy it to a direct buffer to hand it over to the JNI layer. When not enable this mode we may see errors like: 'error:1409F07F:SSL routines:SSL3_WRITE_PENDING: bad write retry'.
Related to https://github.com/netty/netty-tcnative/issues/100.

Modifications:

Explitict set mode to SSL.SSL_MODE_RELEASE_BUFFERS | SSL.SSL_MODE_ACCEPT_MOVING_WRITE_BUFFER . (SSL.SSL_MODE_RELEASE_BUFFERS was used before implicitly).

Result:

No more 'error:1409F07F:SSL routines:SSL3_WRITE_PENDING: bad write retry' possible when writing heap buffers.

e220c56823 [#4746] Support SNI when using OpenSSL
Motivation:

When using SslProvider.OPENSSL we currently not handle SNI on the client side.

Modifications:

b7415a3307 Add a reusable ArrayList to InternalThreadLocalMap
Motivation:

See #3411. A reusable ArrayList in InternalThreadLocalMap can avoid allocations in the following pattern:

```
List<...> list = new ArrayList<...>();

add something to list but never use InternalThreadLocalMap

return list.toArray(new ...[list.size()]);

```

Modifications:

Add a reusable ArrayList to InternalThreadLocalMap and update codes to use it.

Result:

Reuse a thread local ArrayList to avoid allocations.

c3e5604f59 Do not throw IndexOutOfBoundsException on an invalid SSL record
Motivation:

When an SSL record contains an invalid extension data, SniHandler
currently throws an IndexOutOfBoundsException, which is not optimal.

Modifications:

- Do strict index range checks

Result:

No more unnecessary instantiation of exceptions and their stack traces

e1d34ef05d SslHandler should call beginHanshake once for the initial handshake
Motivation:
Not all SSLEngine implementations permit beginHandshake being called while a handshake is in progress during the initial handshake. We should ensure we only go through the initial handshake code once to prevent unexpected exceptions from being thrown.

Modifications:
- Only call beginHandshake if there is not currently a handshake in progress

Result:
SslHandler's handshake method is compatible with OpenSSLEngineImpl in Android 5.0+ and 6.0+.

ee2558bdf3 [#4722] Ensure the whole certificate chain is used when creating SslContext for client mode and SslProvider.OPENSSL is used
Motivation:

We incorrectly added the trustCertChain as certificate chain when OpenSslClientContext was created. We need to correctly add the keyCertChain.

Modifications:

Correctly add whole keyCertChain.

Result:

SSL client auth is working when usin OpenSslClientContext and more then one cert is contained in the certificate chain.

3c5abaa39a Correctly handle non handshake commands when using SniHandler
Motivation:

As we can only handle handshake commands to parse SNI we should try to skip alert and change cipher spec commands a few times before we fallback to use a default SslContext.

Modifications:

- Use default SslContext if no application data command was received
- Use default SslContext if after 4 commands we not received a handshake command
- Simplify code
- Eliminate multiple volatile fields
- Rename SslConstants to SslUtils
- Share code between SslHandler and SniHandler by moving stuff to SslUtils

Result:

Correct handling of non handshake commands and cleaner code.

da01b1daec Decryption failed or bad mac record in Android 5.0
Motivation:

Android 5.0 (API version 21) has a bug which not correctly set the bytesConsumed of SSLEngineResult when HandshakeStatus is FINISHED.  Because of this we need to special handle the status and so workaround the Android bug.

Modifications:

- Break the unwrap for (;;) loop when HandshakeStatus is FINISHED and bytesConsumed == 0 && bytesProduced == 0.

Result:

SslHandler works with all known version of Android.

e578134b57 Unpooled and Wrapped Buffer Leak
Motivation:
There are a few buffer leaks related to how Unpooled.wrapped and Base64.encode is used.

Modifications:
- Fix usages of Bas64.encode to correct leaks
- Clarify interface of Unpooled.wrapped* to ensure reference count ownership is clearly defined.

Result:
Reference count code is more clearly defined and less leaks are possible.

a157528ec2 Ensure we only add OpenSslEngine to the OpenSslEngineMap when handshake is started
Motivation:

We need to ensure we only add the OpenSslEngine to the OpenSslEngineMap when the handshake is started as otherwise we may produce a memory leak when the OpenSslEngine is created but not actually used. This can for example happen if we encounter a connection refused from the remote peer. In this case we will never remove the OpenSslEngine from the OpenSslEngineMap and so it will never be collected (as we hold a reference). This has as affect that the finalizer will never be run as well.

Modifications:

- Lazy add the OpenSslEngine to the OpenSslEngineMap to elimate possible leak.
- Call OpenSslEngine.shutdown() when SslHandler is removed from the ChannelPipeline to free memory asap in all cases.

Result:

No more memory leak with OpenSslEngine if connection is refused.

8732745264 OpenSslEngine skip ALPN tests if OpenSsl version doesn't support ALPN
Motivation:
OpenSslEngine now tests ALPN behavior. However it is possible that OpenSSL is present, but the version does not support ALPN. This will result in test failures instead of just skipping the test.

Modifications:
- Skip ALPN tests in OpenSslEngineTest if the version of OpenSSL does not support ALPN

Result:
Tests don't fail due to unsupported feature in OpenSSL.

fd5316ed6f ChunkedInput.readChunk parameter of type ByteBufAllocator
Motivation:
ChunkedInput.readChunk currently takes a ChannelHandlerContext object as a parameters. All current implementations of this interface only use this object to get the ByteBufAllocator object. Thus taking a ChannelHandlerContext as a parameter is more restrictive for users of this API than necessary.

Modifications:
- Add a new method readChunk(ByteBufAllocator)
- Deprecate readChunk(ChannelHandlerContext) and updates all implementations to call readChunk(ByteBufAllocator)

Result:
API that only requires ByteBufAllocator to use ChunkedInput.

- implement dynamic mapping from hostname to SslContext
- server large number of domain names whose SslContext can be
  initialized lazily and destroyed when unused

Modifications:

- Let SniHandler accept Mapping<String, SslContext> as well as
  DomainNameMapping
- Make the default constructor of SslContext so that a user can create
  his or her own SslContext wrapper

dd9fc289fd Throw exception if KeyManagerFactory is used with OpenSslServerContext
Motivation:

We currently not supported using KeyManagerFactory with OpenSslServerContext and so should throw an exception if the user tries to do so. This will at least not give suprising and hard to debug problems later.

Modifications:

Throw exception if a user tries to construct a OpenSslServerContext with a KeyManagerFactory

Result:

Fail fast if the user tries to use something that is not supported.

eb577c5bd9 Respect ClientAuth set via OpenSslEngine constructor
Motivation:

When ClientAuth is set via SslContextBuilder we pass it into the OpenSslEngine constructor. Due a bug we missed to call the correct native methods and so never enabled ClientAuth in this case.

Modifications:

Correctly call setClientAuth(...) in the constructor if needed.

43ebbc3fa0 Update JDK SSL Tests to use SSL Context Builder.
Motivation:

Use new / non-deprecated APIs for creating SSL Context
in tests, in order to be able to implement OpenSsl
tests with maximum code reuse.

Modifications:

Use `SslContextBuilder.(forServer|forClient)` instead
of deprecated `JdkSslServerContext` constructor.
Use `ApplicationProtocolConfig` instead of Protocol
Negotiator.
Use custom exception type for skipping tests to avoid
swallowing exceptions arising from tests.

Result:

Exceptions from tests aren't swallowed.
Using new APIs allows reusing same test code for
OpenSsl tests.

85236d5446 [#4355] OpenSslServerContext reinitializes the provided TrustManagerFactory with the key cert chain.
Motivation:

OpenSslServerContext should not reinitialize the provided TrustManagerFactory with the key cert chain as the user should be able to pass a fully initialized TrustManagerFactory. This is also in line with how JdkSslServerContext works.

Modifications:

Not reinitialize the provided TrustManagerFactory with the key cert chain.

Result:

5deec9631f Add support for server-side renegotiation when using OpenSslEngine.
Motivation:

JDK SslEngine supports renegotion, so we should at least support it server-side with OpenSslEngine as well.

That said OpenSsl does not support sending messages asynchronly while the renegotiation is still in progress, so the application need to ensure there are not writes going on while the renegotiation takes place. See also https://rt.openssl.org/Ticket/Display.html?id=1019 .

Modifications:

- Add support for renegotiation when OpenSslEngine is used in server mode
- Add unit tests.
- Upgrade to netty-tcnative 1.1.33.Fork9

Result:

Better compatibility with the JDK SSLEngine implementation.

Motivation:

We missed to correctly update the internal handshake state on beginHandshake() if we was able to finish the handshake directly. Also we not handled the case correctly when beginHandshake() was called after the first handshake was finished, which incorrectly throw an Error.

Modifications:

- Correctly set internal handshake state in all cases
- Correctly handle beginHandshake() once first handshake was finished.

58dc7f7902 Do not bother closing SSL enging inbound if the outbound has already been closed.
Motivation:

Invoking the javax.net.ssl.SSLEngine.closeInbound() method will send a
fatal alert and invalidate the SSL session if a close_notify alert has
not been received.
From the javadoc:
If the application initiated the closing process by calling
closeOutbound(), under some circumstances it is not required that the
initiator wait for the peer's corresponding close message. (See section
7.2.1 of the TLS specification (RFC 2246) for more information on
waiting for closure alerts.) In such cases, this method need not be
called.
Always invoking the closeInbound() method without regard to whether or
not the closeOutbound() method has been invoked could lead to
invalidating perfectly valid SSL sessions.

Modifications:

Added an instance variable to track whether the
SSLEngine.closeOutbound() method has been invoked. When the instance
variable is true, the SSLEngine.closeInbound() method doesn't need to be
invoked.

Result:

SSL sessions will not be invalidated if the outbound side has been
closed but a close_notify alert hasn't been received.

052a171a52 Fixes infinite loop during handshake in SslHandler in Android devices
Motivation:

On Android devices with version less than Lollipop, HarmonyJSSE is used for SSL. After completion of handshake, handshake status is NOT_HANDSHAKING instead of FINISHED. Also encrypting empty buffer after handshake should cause underflow exception and produce 0 bytes, but here it happily encrypts it causing for loop to never break

Modification:

Since 0 bytes should only be consumed in handshake process. Added a condition to break loop when 0 bytes are consumed and handshake status is NOT_HANDSHAKING

Result:

Sucessful ssl handshake on Android devices, no infinite loop now

Motivation:

Sometimes the user already has a PrivateKey / X509Certificate which should be used to create a new SslContext. At the moment we only allow to construct it via Files.

Modifications:

- Add new methods to the SslContextBuilder to allow creating a SslContext from PrivateKey / X509Certificate
- Mark all public constructors of *SslContext as @Deprecated, the user should use SslContextBuilder
- Update tests to us SslContextBuilder.
