5d9a5d3e8d Revert SslEngineWrapperFactory api breakage introduced by 4448b8f42f.
Motivation:

Commit 4448b8f42f introduced some API breakage which we need to revert before we release.

Modifications:

- Introduce an AllocatorAwareSslEngineWrapperFactory which expose an extra method that takes a ByteBufAllocator as well.
- Revert API changes to SslEngineWrapperFactory.

Result:

API breakage reverted.

d63bb4811e Only call ctx.fireChannelReadComplete() if ByteToMessageDecoder decoded at least one message.
Motivation:

Its wasteful and also confusing that channelReadComplete() is called even if there was no message forwarded to the next handler.

Modifications:

- Only call ctx.fireChannelReadComplete() if at least one message was decoded
- Add unit test

Result:

Less confusing behavior. Fixes [#4312].

32f497760f Ensure no java.lang.UnsupportedClassVersionError are thrown if running on Java7 and try to check if conscrypt is available.
Motivation:

We need to ensure we not try to load any conscrypt classes directly (which means without using reflection) in the same class that is used to check if conscrypt is available. This is needed as otherwise we will have the following problem when try to use netty on java7:

java.lang.UnsupportedClassVersionError: org/conscrypt/BufferAllocator : Unsupported major.minor version 52.0
	at io.netty.handler.ssl.ConscryptJdkSslEngineInteropTest.checkConscrypt(ConscryptJdkSslEngineInteropTest.java:49)

This regression was introduced by 4448b8f42f and detected on the CI when using:

mvn clean package -DtestJavaHome=$JAVA7_HOME

Modifications:

Move the detection code in an extra class and use it.

Result:

Works correctly also when using Java7.

4448b8f42f Upgrading to Conscrypt 1.0.0.RC9. (#7044)
Motivation:

Starting with 1.0.0.RC9, conscrypt supports a buffer allocator.

Modifications:

- Updated the creation process for the engine to pass through the
ByteBufAllocator.
- Wrap a ByteBufAllocator with an adapter for conscrypt.
- Added a property to optionally control whether conscrypt uses
Netty's buffer allocator.

Result:

Netty+conscrypt will support using Netty's ByteBufAllocator.

c5b5d36360 Fix false-positive leak detection report when ReferenceCountedOpenSslEngine constructor throws.
Motivation:

We need to ensure we only create the ResourceLeak when the constructor not throws.

Modifications:

Ensure ResourceLeakDetector.track(...) is only called if the constructor of ReferenceCoundedOpenSslEngine not throws.

Result:

No more false-positves.

452fd36240 ByteBufs which are not resizable should not throw in ensureWritable(int,boolean)
Motivation:
ByteBuf#ensureWritable(int,boolean) returns an int indicating the status of the resize operation. For buffers that are unmodifiable or cannot be resized this method shouldn't throw but just return 1.
ByteBuf#ensureWriteable(int) should throw unmodifiable buffers.

Modifications:
- ReadOnlyByteBuf should be updated as described above.
- Add a unit test to SslHandler which verifies the read only buffer can be tolerated in the aggregation algorithm.

Result:
Fixes https://github.com/netty/netty/issues/7002.

2fbce6d470 Delete temporary self-signed certs in SSLEngineTest-based tests
Motivation:

Lots of usages of SelfSignedCertificates were not deleting the certs at
the end of the test. This includes setupHandlers() which is used by
extending classes. Although these files will be deleted at JVM exit and
deleting them early does not free the JVM from trying to delete them at
shutdown, it's good practice to delete eagerly and since users sometimes
use tests as a form of documentation, it'd be good for them to see the
explicit deletes.

Modifications:

Add missing delete() calls to ½ of the SelfSignedCertificates-using
tests.

Result:

Tests that more clearly communicates which resources are created and
may accumulate without early delete.

8a25c35939 Filter user-provided ciphers using RFC cipher names
Motivation:

Previously filterCipherSuites was being passed the OpenSSL-formatted
cipher names. Commit 43ae974 introduced a regression as it swapped to the
RFC/JDK format, except that user-provided ciphers were not converted and
remained in the OpenSSL format.

This mis-match would cause all user-provided to be thrown away, leading
to failure trying to set zero ciphers:
Exception in thread "main" javax.net.ssl.SSLException: failed to set cipher suite: []

	at io.netty.handler.ssl.ReferenceCountedOpenSslContext.<init>(ReferenceCountedOpenSslContext.java:295)
	... 7 more

Modifications:

Remove the reformatting of user-provided ciphers, as they are already in
the RFC/JDK format.

Result:

No regression, and the internals stay sane using the RFC/JDK format.

ef22e65b57 Allow to delay registration when creating a EmbeddedChannel
Motivation:

Some ChannelOptions must be set before the Channel is really registered to have the desired effect.

Modifications:

Add another constructor argument which allows to not register the EmbeddedChannel to its EventLoop until the user calls register().

Result:

More flexible usage of EmbeddedChannel. Also Fixes [#6968].

64a3e6c69c SSLEngineTest should not depend on OpenSsl* class.
Motivation:

6152990073 introduced a test-case in SSLEngineTest which used OpenSsl.* which should not be done as this is am abstract bass class that is also used for non OpenSsl tests.

Modifications:

Move the protocol definations into SslUtils.

Result:

Cleaner code.

6152990073 OpenSslEngine protocol selection must be contiguous
Motivation:
TLS doesn't support a way to advertise non-contiguous versions from the client's perspective, and the client just advertises the max supported version. The TLS protocol also doesn't support all different combinations of discrete protocols, and instead assumes contiguous ranges. OpenSSL has some unexpected behavior (e.g. handshake failures) if non-contiguous protocols are used even where there is a compatible set of protocols and ciphers. For these reasons this method will determine the minimum protocol and the maximum protocol and enabled a contiguous range from [min protocol, max protocol] in OpenSSL.

Modifications:
- ReferenceCountedOpenSslEngine#setEnabledProtocols should determine the min/max protocol versions and enable a contiguous range

Result:
OpenSslEngine is more consistent with the JDK's SslEngineImpl and no more unexpected handshake failures due to protocol selection quirks.

43ae9748d0 Unify default cipher suites betweek JDK and OpenSSL
Motivation:
Currently the default cipher suites are set independently between JDK and OpenSSL. We should use a common approach to setting the default ciphers. Also the OpenSsl default ciphers are expressed in terms of the OpenSSL cipher name conventions, which is not correct and may be exposed to the end user. OpenSSL should also use the RFC cipher names like the JDK defaults.

Modifications:
- Move the default cipher definition to a common location and use it in JDK and OpenSSL initialization
- OpenSSL should not expose OpenSSL cipher names externally

Result:
Common initialization and OpenSSL doesn't expose custom cipher names.

e5455d31b3 Fix Race in ReferenceCountedOpenSslEngine
Motivation:
ReferenceCountedOpenSslEngine is careful to lock access to `ssl`
almost everywhere (manually verified) *except* in the constructor.
Since `ssl` is non-final, it does not enjoy automatic thread safety
of the code that uses it.  Specifically, that means netty tcnative
code is not thread safe.

Modifications:

Ensure that all ssl engine intialization and variables related to
it are properly synchronized  by adding in the constructor.

Result:
Less noisy race detector.

Notes:
The specific racing threads are:

81fb2eede8 Revert "Revert "SslHandler avoid calling wrap/unwrap when unnecessary""
Motivation:
PR https://github.com/netty/netty/pull/6803 corrected an error in the return status of the OpenSslEngine. We should now be able to restore the SslHandler optimization.

Modifications:

86e653e04f SslHandler aggregation of plaintext data on write
Motivation:
Each call to SSL_write may introduce about ~100 bytes of overhead. The OpenSslEngine (based upon OpenSSL) is not able to do gathering writes so this means each wrap operation will incur the ~100 byte overhead. This commit attempts to increase goodput by aggregating the plaintext in chunks of <a href="https://tools.ietf.org/html/rfc5246#section-6.2">2^14</a>. If many small chunks are written this can increase goodput, decrease the amount of calls to SSL_write, and decrease overall encryption operations.

Modifications:
- Introduce SslHandlerCoalescingBufferQueue in SslHandler which will aggregate up to 2^14 chunks of plaintext by default
- Introduce SslHandler#setWrapDataSize to control how much data should be aggregated for each write. Aggregation can be disabled by setting this value to <= 0.

Result:
Better goodput when using SslHandler and the OpenSslEngine.

f7b3caeddc OpenSslEngine option to wrap/unwrap multiple packets per call
Motivation:
The JDK SSLEngine documentation says that a call to wrap/unwrap "will attempt to consume one complete SSL/TLS network packet" [1]. This limitation can result in thrashing in the pipeline to decode and encode data that may be spread amongst multiple SSL/TLS network packets.
ReferenceCountedOpenSslEngine also does not correct account for the overhead introduced by each individual SSL_write call if there are multiple ByteBuffers passed to the wrap() method.

Modifications:
- OpenSslEngine and SslHandler supports a mode to not comply with the limitation to only deal with a single SSL/TLS network packet per call
- ReferenceCountedOpenSslEngine correctly accounts for the overhead of each call to SSL_write
- SslHandler shouldn't cache maxPacketBufferSize as aggressively because this value may change before/after the handshake.

Result:
OpenSslEngine and SslHanadler can handle multiple SSL/TLS network packet per call.

449befa003 Workaround IBM's J9 JVM getSupportedCipherSuites() returning SSL_ prefix cipher names
Motivation:
IBM's J9 JVM utilizes a custom cipher naming scheme with SSL_ prefix [1] instead of the TLS_ prefix defined by TLS RFCs and the JSSE cihper suite names [2]. IBM's documentation says that the SSL_ prefix are "interchangeable" with cipher names with the TLS_ prefix [1]. To work around this issue we parse the supported cipher list and see an SSL_ prefix we can also add the same cipher with the TLS_ prefix. For more details see a discussion on IBM's forums [3] and IBM's issue tracker [4].

[4] https://www.ibm.com/developerworks/rfe/execute?use_case=viewRfe&CR_ID=71770

Modifications:
- When parsing the supported cipher list to get the supported ciphers and we encounter a SSL_ prefix we should also add a TLS_ prefix cipher.
- Remove SSL_ prefix ciphers from Http2SecurityUtil.

Result:
Work around for IBM JVM's custom naming scheme covers more cases for supported cipher suites.

83de77fbe5 Make Native loading work better with Java 8
Motivation:
Enable static linking for Java 8.  These commits are the same as those introduced to netty tcnative.  The goal is to allow lots of JNI libraries to be statically linked together without having conflict `JNI_OnLoad` methods.

Modification:
* add JNI_OnLoad suffixes to enable static linking
* Add static names to the list of libraries that try to be loaded
* Enable compiling with JNI 1.8
* Sort includes

Result:
Enable statically linked JNI code.

01eb428b39 Move methods for decode hex dump into StringUtil
Motivation:

PR #6811 introduced a public utility methods to decode hex dump and its parts, but they are not visible from netty-common.

Modifications:

1. Move the `decodeHexByte`, `decodeHexDump` and `decodeHexNibble` methods into `StringUtils`.
2. Apply these methods where applicable.
3. Remove similar methods from other locations (e.g. `HpackHex` test class).

Result:

6d029ad3ac OpenSSL CHACHA20 CipherSuiteConverter updates
Motivation:
For historical reasons OpenSSL's internal naming convention for CHACHA20 based cipher suites does not include the HMAC algorithm in the cipher name. This will prevent the CHACHA20 cipher suites from being used if the RFC cipher names are specified.

Modifications:
- Add a special case for CHACHA20 cipher name conversions in CipherSuiteConverter
- Update OPENSSL_CIPHERSUITE_PATTERN to accommodate the new naming scheme for CHACHA20 cipher suites

Result:
CipherSuiteConverter now works with CHACHA20 cipher suites.

7460d90a67 Add listener to returned Future rather than passed in Promise
Motivation

It's cleaner to add listeners to returned Futures rather than provided Promises because the latter can have strange side effects in terms of listeners firing and called methods returning. Adding listeners preemtively may yield also to more OPS than necessary when there's an Exception in the to be called method.

Modifications

Add listener to returned ChannelFuture rather than given ChannelPromise

Result

e597756a56 Remove synchronized (ReferenceCountedOpenSslContext.class) blocks
Motivation:

We had some useless synchronized (ReferenceCountedOpenSslContext.class) blocks in our code which could slow down concurrent collecting and creating of ReferenceCountedOpenSslContext instances. Beside this we missed a few guards.

Modifications:

Use ReadWriteLock to correctly guard. A ReadWriteLock was choosen as SSL.newSSL(...) will be called from multiple threads all the time so using synchronized would be worse and there would be no way for the JIT to optimize it away

Result:

Faster concurrent creating and collecting of ReferenceCountedOpenSslContext instances and correctly guard in all cases.

24f801c7d1 OpenSslEngine return NEED_WRAP if the destination buffered filled
Motivation:
If the destination buffer is completely filled during a call to OpenSslEngine#wrap(..) we may return NEED_UNWRAP because there is no data pending in the SSL buffers. However during a handshake if the SSL buffers were just drained, and filled up the destination buffer it is possible OpenSSL may produce more data on the next call to SSL_write. This means we should keep trying to call SSL_write as long as the destination buffer is filled and only return NEED_UNWRAP when the destination buffer is not full and there is no data pending in OpenSSL's buffers.

Modifications:
- If the handshake produces data in OpenSslEngine#wrap(..) we should return NEED_WRAP if the destination buffer is completely filled

Result:
OpenSslEngine returns the correct handshake status from wrap().

Motivation:

SslHandler#wrapNonAppData may be able to return early if it is called from a unwrap method and the status is NEED_UNWRAP. This has been observed to occur while using the OpenSslEngine and can avoid allocation of an extra ByteBuf of size 2048.

Modifications:
- Return early from SslHandler#wrapNonAppData if NEED_UNWRAP and we are called from an unwrap method

Result:
Less buffer allocations and early return from SslHandler#wrapNonAppData.

141089998f OpenSslEngine wrap may generate bad data if multiple src buffers
Motivation:
SSL_write requires a fixed amount of bytes for overhead related to the encryption process for each call. OpenSslEngine#wrap(..) will attempt to encrypt multiple input buffers until MAX_PLAINTEXT_LENGTH are consumed, but the size estimation provided by calculateOutNetBufSize may not leave enough room for each call to SSL_write. If SSL_write is not able to completely write results to the destination buffer it will keep state and attempt to write it later. Netty doesn't account for SSL_write keeping state and assumes all writes will complete synchronously (by attempting to allocate enough space to account for the overhead) and feeds the same data to SSL_write again later which results in corrupted data being generated.

Modifications:
- OpenSslEngine#wrap should only produce a single TLS packet according to the SSLEngine API specificaiton [1].
[1] https://docs.oracle.com/javase/8/docs/api/javax/net/ssl/SSLEngine.html#wrap-java.nio.ByteBuffer:A-int-int-java.nio.ByteBuffer-
- OpenSslEngine#wrap should only consider a single buffer when determining if there is enough space to write, because only a single buffer will ever be consumed.

Result:
OpenSslEngine#wrap will no longer produce corrupted data due to incorrect accounting of space required in the destination buffers.

Motivation

SniHandler is "hardcoded" to use hostname -> SslContext mappings but there are use-cases where it's desireable and necessary to return more information than a SslContext. The only option so far has been to use a delegation pattern

Modifications

Extract parts of the existing SniHandler into an abstract base class and extend SniHandler from it. Users can do the same by extending the new abstract base class and implement custom behavior that is possibly very different from the common/default SniHandler.

077a1988b9 OCSP stapling support for Netty using netty-tcnative.
https://github.com/netty/netty-tcnative/pull/215

Motivation

OCSP stapling (formally known as TLS Certificate Status Request extension) is alternative approach for checking the revocation status of X.509 Certificates. Servers can preemptively fetch the OCSP response from the CA's responder, cache it for some period of time, and pass it along during (a.k.a. staple) the TLS handshake. The client no longer has to reach out on its own to the CA to check the validity of a cetitficate. Some of the key benefits are:

1) Speed. The client doesn't have to crosscheck the certificate.
2) Efficiency. The Internet is no longer DDoS'ing the CA's OCSP responder servers.
3) Safety. Less operational dependence on the CA. Certificate owners can sustain short CA outages.
4) Privacy. The CA can lo longer track the users of a certificate.

Result:

With this change, softwares using Netty + OpenSSL will be able to respond for TLS Heartbeat requests (actually taken care by OpenSSL - no need of any extra implementation from Clients)

61f53c4d07 ChunkedWriteHandler flushes too often
Motivation:

ChunkedWriteHandler queues written messages and actually writes them
when flush is called. In its doFlush method, it needs to flush after
each chunk is written to preserve memory. However, non-chunked messages
(those that aren't of type ChunkedInput) are treated in the same way,
which means that flush is called after each message is written.

Modifications:

Moved the call to flush() inside the if block that tests if the message
is an instance of ChunkedInput. To ensure flush is called at least once,
the existing boolean flushed is checked at the end of doFlush. This
check was previously in ChunkedWriteHandler.flush(), but wasn't checked in
other invocations of doFlush, e.g. in channelInactive.

Result:

When this handler is present in a pipeline, writing a series
of non-chunked messages will be flushed as the developer intended.

Motivation:
SslContext and SslContextBuilder do not support a way to specify the desired TLS protocols. This currently requires that the user extracts the SSLEngine once a context is built and manually call SSLEngine#setEnabledProtocols(String[]). Something this critical should be supported at the SslContext level.

Modifications:
- SslContextBuilder should accept a list of protocols to configure for each SslEngine

SslContext consistently sets the supported TLS/SSL protocols.

Modifications:
- We should check if the OpenSSL library supports the KeyManagerFactory interfaces and if the system property allows them to be used in OpenSslEngineTests

Result:
Unit tests which use OpenSSL and KeyManagerFactory will be skipped instead of failing.

53fc693901 SslHandler and OpenSslEngine miscalculation of wrap destination buffer size
Motivation:
When we do a wrap operation we calculate the maximum size of the destination buffer ahead of time, and return a BUFFER_OVERFLOW exception if the destination buffer is not big enough. However if there is a CompositeByteBuf the wrap operation may consist of multiple ByteBuffers and each incurs its own overhead during the encryption. We currently don't account for the overhead required for encryption if there are multiple ByteBuffers and we assume the overhead will only apply once to the entire input size. If there is not enough room to write an entire encrypted packed into the BIO SSL_write will return -1 despite having actually written content to the BIO. We then attempt to retry the write with a bigger buffer, but because SSL_write is stateful the remaining bytes from the previous operation are put into the BIO. This results in sending the second half of the encrypted data being sent to the peer which is not of proper format and the peer will be confused and ultimately not get the expected data (which may result in a fatal error). In this case because SSL_write returns -1 we have no way to know how many bytes were actually consumed and so the best we can do is ensure that we always allocate a destination buffer with enough space so we are guaranteed to complete the write operation synchronously.

Modifications:
- SslHandler#allocateNetBuf should take into account how many ByteBuffers will be wrapped and apply the encryption overhead for each
- Include the TLS header length in the overhead computation

Result:

1f6782894a OpenSslEngine wrap with heap buffer bug
Motivation:
ReferenceCountedOpenSslEngine#wrap must have a direct buffer for a destination to interact with JNI. If the user doesn't supply a direct buffer we internally allocate one to write the results of wrap into. After this operation completes we copy the contents of the direct buffer into the heap buffer and use internalNioBuffer to get the content. However we pass in the end index but the internalNioBuffer expects a length.

Modifications:
- pass the length instead of end index to internalNioBuffer

Result:
ReferenceCountedOpenSslEngine#wrap will copy the correct amount of data into the destination buffer when heap buffers are wrapped.

Motivation:
To ensure that all bytes queued in OpenSSL/tcnative internal buffers we invoke SSL_shutdown again to stimulate OpenSSL to write any pending bytes.

325cc84a2e Throw if SSLParameters contains settings that are not supported by ReferenceCountedOpenSslEngine
Motivation:

We not support all SSLParameters settings so we should better throw if a user try to use them.

Modifications:

- Check for unsupported parameters
- Add unit test

Result:

Less surprising behavior.

e08a3b1f35 Fix SSLException check for JDK work around missed by 2dffc2f9fb 2017-02-20 21:38:04 -08:00
Scott Mitchell
2dffc2f9fb SSLEngineTest issue introduced by d8e6fbb9c3
Motivation:
d8e6fbb9c3 attempted to account for the JDK not throwing the expected SSLHandshakeException by allowing a SSLException to also pass the test. However in some situations the SSLException will not be the top level exception and the Throwable must be unwrapped to see if the root cause is an SSLException.

Modifications:
- Unwrap exceptions thrown by the JDK's SSLEngine to check for SSLException.

Result:
SSLEngineTest (and derived classes) are more reliable.

c57a1bdb2d Log used native library by netty-tcnative
Motivation:

As netty-tcnative can be build against different native libraries and versions we should log the used one.

Modifications:

Log the used native library after netty-tcnative was loaded.

Result:

Easier to understand what native SSL library was used.

d8e6fbb9c3 OpenSslEngine should respect hostname verification
Motivation:
OpenSSL doesn't automatically verify hostnames and requires extract method calls to enable this feature [1]. We should allow this to be configured.

Modifications:
- SSLParamaters#getEndpointIdentificationAlgorithm() should be respected and configured via tcnative interfaces.

Result:
OpenSslEngine respects hostname verification.

Modification:

Using ThreadLocalRandom implementation of the JDK when possible.

Result:

Make use of JDK implementations when possible.

b2f7e8648e Fix ReferenceCountedOpenSslEngine.getEnabledProtocols() when using boringssl
Motivation:

Commit cd3bf3df58 made netty observe the latest version of netty-tcnative which changed the way how static fields are computed for various SSL.* values. This lead to have SSL_OP_NO_SSLv2 become 0 when using boringssl as boringssl not supports SSLv2 at all. In the logic of ReferenceCountedOpenSslEngine.getEnabledProtocols() we not expect to have a zero value and so our logic fails.

Modifications:

Check we actual support the protocol before return it as enabled.

Result:

SSLEngineTest.testEnablingAnAlreadyDisabledSslProtocol passes again with boringssl

4431ad894d OpenSslEngine may lose data if the non-application buffer is small/full
Motivation:
If an event occurs which generates non-application data (shutdown, handshake failure, alert generation, etc...) and the non-application buffer in the ByteBuffer BIO is full (or sufficiently small) we may not propagate all data to our peer before tearing down the socket.

Modifications:
- when wrap() detects the outbound is closed, but there is more data pending in the non-application buffers, we must also check if OpenSSL will generate more data from calling SSL_shutdown again
- when wrap() detects a handshakeExcpetion during failure we should check if OpenSSL has any pending data (in addition to the non-application buff) before throwing the handshake exception

Result:
OpenSslEngine more reliably transmits data to the peer before closing the socket.

43a2315372 Skip SSLEngineTests that depend on KeyManagerFactory when this is not supported by the openssl version.
Motivation:

Some version of openssl dont support the needed APIs to use a KeyManagerFactory. In this case we should skip the tests.

Modifications:

- Use assumeTrue(...) to skip tests that need a KeyManagerFactory and its not supported.

Result:

Tests pass on all openssl versions we support.

d60e37cb3d OpenSslEngine wrap may not consume all data
Motivation:
If the OpenSslEngine has bytes pending in the non-application buffer and also generates wrapped data during the handshake then the handshake data will be missed. This will lead to a handshake stall and eventually timeout. This can occur if the non-application buffer becomes full due to a large certificate/hello message.

Modification:
- ReferenceCountedOpenSslEngine should not assume if no data is flushed from the non-application buffer that no data will be produced by the handshake.

Result:
New unit tests with larger certificate chains don't fail.

6765e9f99d CipherSuiteConverter NPE
Motivation:
CipherSuiteConverter may throw a NPE if a cipher suite from OpenSSL does not match the precomputed regular expression for OpenSSL ciphers. This method shouldn't throw and instead just return null.

Modifications:
- if cacheFromOpenSsl(..) fails the conversion toJava should return null

d06990f434 OpenSSL ByteBuffer BIO
Motivation:
Currently Netty utilizes BIO_new_bio_pair so we can control all FD lifetime and event notification but delegates to OpenSSL for encryption/decryption. The current implementation sets up a pair of BIO buffers to read/write encrypted/plaintext data. This approach requires copying of data from Java ByteBuffers to native memory BIO buffers, and also requires both BIO buffers to be sufficiently large to hold application data. If direct ByteBuffers are used we can avoid coyping to/from the intermediate BIO buffer and just read/write directly from the direct ByteBuffer memory. We still need an internal buffer because OpenSSL may generate write data as a result of read calls (e.g. handshake, alerts, renegotiation, etc..), but this buffer doesn't have to be be large enough to hold application data.

Modifications:
- Take advantage of the new ByteBuffer based BIO provided by netty-tcnative instead of using BIO_read and BIO_write.

Result:
Less copying and lower memory footprint requirement per TLS connection.

6353c229fd SslHandler avoid calling wrap/unwrap when unnecessary
Motivation:
The SSLEngine wrap and unwrap methods can be called in a way that has no side effects, but this could involve costly validation and allocation. The SslHandler should avoid calling into these methods if possible.

Modifications:
- wrapNonAppData should provide additional status which can be used by wrap to breakout early if possible

Result:
SslHandler invokes the SSLEngine less.

1d128c7a65 Switch to netty-tcnative 2.0.0 which uses different package names
Motivation:

Previous versions of netty-tcnative used the org.apache.tomcat namespace which could lead to problems when a user tried to use tomcat and netty in the same app.

Modifications:

Use netty-tcnative which now uses a different namespace and adjust code to some API changes.

Result:

Its now possible to use netty-tcnative even when running together with tomcat.

7736534b34 Ensure tests added in 91f050d2ef work with different openssl installations
Motivation:

Tests were added in 91f050d2ef to run with different protocols / ciphers. These may fail currently when openssl was compiled without support for the protocol / ciphers.

Modifications:

- Refactor tests to easier understand for which protocol / cipher it failed
- Not fail the test if the protocol is not supported with the used openssl version.

Motivation:

We failed to properly test if a protocol is supported on an OpenSSL installation and just always returned all protocols.

91f050d2ef More precise calculate the maximum record size when using SslProvider.OPENSSL* and so decrease mem usage.
Motivation:

We used ca 2k as maximum overhead for encrypted packets which is a lot more then what is needed in reality by OpenSSL. This could lead to the need of more memory.

Modification:

- Use a lower overhead of 86 bytes as defined by the spec and openssl itself
- Fix unit test to use the correct session to calculate needed buffer size

Result:

Less memory usage.

640ef615be Allow to configure SslHandler to wait for close_notify response before closing the Channel and fix racy flush close_notify timeout scheduling.
Motivation:

SslHandler closed the channel as soon as it was able to write out the close_notify message. This may not be what the user want as it may make sense to only close it after the actual response to the close_notify was received in order to guarantee a clean-shutdown of the connection in all cases.

Beside this closeNotifyFlushTimeoutMillis is volatile so may change between two reads. We need to cache it in a local variable to ensure it not change int between. Beside this we also need to check if the flush promise was complete the schedule timeout as this may happened but we were not able to cancel the timeout yet. Otherwise we will produce an missleading log message.

Modifications:

- Add new setter / getter to SslHandler which allows to specify the behavior (old behavior is preserved as default)
- Added unit test.
- Cache volatile closeNotifyTimeoutMillis.
- Correctly check if flush promise was complete before we try to forcibly close the Channel and log a warning.
- Add missing javadocs.

Result:

More clean shutdown of connection possible when using SSL and fix racy way of schedule close_notify flush timeouts and javadocs.

e9fa40d770 Ensure calling ReferenceCountedOpenSslEngine.wrap(...) after closeOutbound() was called will not throw an SSLException
Motivation:

PR [#6238] added guards to be able to call wrap(...) / unwrap(...) after the engine was shutdown. Unfortunally one case was missed which is when closeOutbound() was called and produced some data while closeInbound() was not called yet.

Modifications:

Correctly guard against SSLException when closeOutbound() was called, produced data and someone calls wrap(...) after it.

Result:

No more SSLException. Fixes [#6260].

ac5f701a5c Use less memory during writes when using SslHandler with SslProvider.OpenSsl
Motivation:

In commit fc3c9c9523 I changes the way how we calculate the capacity of the needed ByteBuf for wrap operations that happen during writes when the SslHandler is used. This had the effect that the same capacity for ByteBufs is needed for the JDK implementation of SSLEngine but also for our SSLEngine implementation that uses OpenSSL / BoringSSL / LibreSSL. Unfortunally this had the side-effect that applications that used our SSLEngine implementation now need a lot more memory as bascially the JDK implementation always needs a 16kb buffer for each wrap while we can do a lot better for our SSLEngine implementation.

Modification:

- Resurrect code that calculate a better ByteBuf capacity when using our SSLEngine implementation and so be able to safe a lot of memory
- Add test-case to ensure it works as expected and is not removed again later on.

Result:

Memory footprint of applications that uses our SSLEngine implementation based on OpenSSL / BoringSSL / LibreSSL is back to the same amount of before commit fc3c9c9523.

3344cd21ac Wrap operations requiring SocketPermission with doPrivileged blocks
Motivation:

Currently Netty does not wrap socket connect, bind, or accept
operations in doPrivileged blocks. Nor does it wrap cases where a dns
lookup might happen.

This prevents an application utilizing the SecurityManager from
isolating SocketPermissions to Netty.

Modifications:

I have introduced a class (SocketUtils) that wraps operations
requiring SocketPermissions in doPrivileged blocks.

Result:

A user of Netty can grant SocketPermissions explicitly to the Netty
jar, without granting it to the rest of their application.

Motivation:

The JDK implementation of SSLEngine allows to have unwrap(...) / wrap(...) called even after closeInbound() and closeOutbound() were called. We need to support the same in ReferenceCountedSslEngine.

Modification:

- Allow calling ReferenceCountedSslEngine.unwrap(...) / wrap(...) after the engine was closed
- Modify unit test to ensure correct behaviour.

dd055c01c7 Ensure ReferenceCountedOpenSslEngine not swallow the close_notify
Motivation:

We need to ensure we not swallow the close_notify that should be send back to the remote peer. See [#6167]

Modifications:

- Only call shutdown() in closeInbound() if there is nothing pending that should be send back to the remote peer.
- Return the correct HandshakeStatus when the close_notify was received.
- Only shutdown() when close_notify was received after closeOutbound() was called.

Result:

close_notify is correctly send back to the remote peer and handled when received.

Motivation:

In later Java8 versions our Atomic*FieldUpdater are slower then the JDK implementations so we should not use ours anymore. Even worse the JDK implementations provide for example an optimized version of addAndGet(...) using intrinsics which makes it a lot faster for this use-case.

Modifications:

- Remove methods that return our own Atomic*FieldUpdaters.
- Use the JDK implementations everywhere.

Motivation:

We need to ensure we handle the case when BUFFER_OVERFLOW happens during unwrap but the readable bytes are bigger then the expected applicationBufferSize. Otherwise we may produce an IllegalArgumentException as we will try to allocate a buffer with capacity < 0.

Modifications:

- Guard against this case.

c2f4daa739 Fix false-positives when using ResourceLeakDetector.
Motivation:

We need to ensure the tracked object can not be GC'ed before ResourceLeak.close() is called as otherwise we may get false-positives reported by the ResourceLeakDetector. This can happen as the JIT / GC may be able to figure out that we do not need the tracked object anymore and so already enqueue it for collection before we actually get a chance to close the enclosing ResourceLeak.

Modifications:

- Add ResourceLeakTracker and deprecate the old ResourceLeak
- Fix some javadocs to correctly release buffers.
- Add a unit test for ResourceLeakDetector that shows that ResourceLeakTracker has not the problems.

Result:

No more false-positives reported by ResourceLeakDetector when ResourceLeakDetector.track(...) is used.

7ce0f35b69 Correctly not try to call handshake() when engine is already closed.
Motivation:

We need to ensure we not call handshake() when the engine is already closed. Beside this our implementation of isOutboundDone() was not correct as it not took the pending data in the outbound buffer into acount (which may be also generated as part of an ssl alert). Beside this we also called SSL_shutdown(...) while we were still in init state which will produce an error and so noise in the log with openssl later versions.

This is also in some extend related to #5931 .

Modifications:

- Ensure we not call handshake() when already closed
- Correctly implement isOutboundDone()
- Not call SSL_shutdown(...) when still in init state

0ca2c3016b Correct guard against non SSL data in ReferenceCountedOpenSslEngine
Motivation:

When non SSL data is passed into SSLEngine.unwrap(...) we need to throw an SSLException. This was not done at the moment. Even worse we threw an IllegalArgumentException as we tried to allocate a direct buffer with capacity of -1.

Modifications:

- Guard against non SSL data and added an unit test.
- Make code more consistent

Result:

Correct behaving SSLEngine implementation.

f332a00e1a Support compiling netty with Java9
Motivation:

Java9 will be released soon so we should ensure we can compile netty with Java9 and run all our tests. This will help to make sure Netty will be usable with Java9.

Modification:

- Add some workarounds to be able to compile with Java9, note that the full profile is not supported with Java9 atm.
- Remove some usage of internal APIs to be able to compile on java9
- Not support Alpn / Npn and so not run the tests when using Java9 for now. We will do a follow up PR to add support.

Result:

Its possible to build netty and run its testsuite with Java9.

6dbec4181c Ensure we not complete the same promise that may be failed because of outbound handler exception.
Motivation:

It's important that we do not pass in the original ChannelPromise to safeClose(...) as when flush(...) will throw an Exception it will be propagated to the AbstractChannelHandlerContext which will try to fail the promise because of this. This will then fail as it was already completed by safeClose(...).

Modifications:

Create a new ChannelPromise and pass it to safeClose(...).

Result:

No more confusing logs because of failing to fail the promise.

55c291ae5b SslHandlerTest ByteBuf leak
Motivation:
We are now more careful to flush alerts that are generated when errors occur. We should also be more careful in unit tests to release any buffers that may be queued due to potential errors wich result in alerts.

Modifications:
- When SslHandlerTest uses EmbeddedChannel we should always call finishAndReleaseAll

Results:

f289ebf7fa Ensure alert is send when SSLException happens during calling SslHandler.unwrap(...)
Motivation:

When the SslHandler.unwrap(...) (which is called via decode(...)) method did produce an SSLException it was possible that the produced alert was not send to the remote peer. This could lead to staling connections if the remote peer did wait for such an alert and the connection was not closed.

Modifications:

- Ensure we try to flush any pending data when a SSLException is thrown during unwrapping.
- Fix SniHandlerTest to correct test this
- Add explicit new test in SslHandlerTest to verify behaviour with all SslProviders.

Result:

The alert is correctly send to the remote peer in all cases.

9b7fb2f362 Use the correct alert depending on the CertificateException when using OpenSslEngine
Motivation:

We tried to detect the correct alert to use depending on the CertificateException that is thrown by the TrustManager. This not worked all the time as depending on the TrustManager implementation it may also wrap a CertPathValidatorException.

Modification:

- Try to unwrap the CertificateException if needed and detect the right alert via the CertPathValidatorException.
- Add unit to verify

Result:

Send the correct alert depending on the CertificateException when using OpenSslEngine.

0bc30a123e Eliminate usage of releaseLater(...) to reduce memory usage during tests
Motiviation:

We used ReferenceCountUtil.releaseLater(...) in our tests which simplifies a bit the releasing of ReferenceCounted objects. The problem with this is that while it simplifies stuff it increase memory usage a lot as memory may not be freed up in a timely manner.

Modifications:

- Deprecate releaseLater(...)
- Remove usage of releaseLater(...) in tests.

Result:

Less memory needed to build netty while running the tests.

Modifications:

Ensure tests pass with JDK and OPENSSL ssl implementations.

Result:

SniHandlerTest will run with all SslProvider and not fail when SslProvider.JDK is used.

c8575c42d0 [#5976] Ensure we only consume as much data on wrap(...) as we can handle.
Motiviation:

We need to ensure we only consume as much da as we can maximal put in one ssl record to not produce a BUFFER_OVERFLOW when calling wrap(...).

Modification:

- Limit the amount of data that we consume based on the maximal plain text size that can be put in one ssl record
- Add testcase to verify the fix
- Tighten up testcases to ensure the amount of produced and consumed data in SslEngineResult matches the buffers. If not the tests will fail now.

Result:

Correct and conform behavior of OpenSslEngine.wrap(...) and better test coverage during handshaking in general.

c1932a8537 ByteBuf Input Stream Reference Count Ownership
Motivation:
Netty provides a adaptor from ByteBuf to Java's InputStream interface. The JDK Stream interfaces have an explicit lifetime because they implement the Closable interface. This lifetime may be differnt than the ByteBuf which is wrapped, and controlled by the interface which accepts the JDK Stream. However Netty's ByteBufInputStream currently does not take reference count ownership of the underlying ByteBuf. There may be no way for existing classes which only accept the InputStream interface to communicate when they are done with the stream, other than calling close(). This means that when the stream is closed it may be appropriate to release the underlying ByteBuf, as the ownership of the underlying ByteBuf resource may be transferred to the Java Stream.

Motivation:
- ByteBufInputStream.close() supports taking reference count ownership of the underyling ByteBuf

Result:
ByteBufInputStream can assume reference count ownership so the underlying ByteBuf can be cleaned up when the stream is closed.

fc3c9c9523 Let OpenSslEngine.wrap(...) / OpenSslEngine.unwrap(...) behave like stated in the javadocs.
Motivation:

OpenSslEngine.wrap(...) and OpenSslEngie.unwrap(...) may consume bytes even if an BUFFER_OVERFLOW / BUFFER_UNDERFLOW is detected. This is not correct as it should only consume bytes if it can process them without storing data between unwrap(...) / wrap(...) calls. Beside this it also should only process one record at a time.

Modifications:

- Correctly detect BUFFER_OVERFLOW / BUFFER_UNDERFLOW and only consume bytes if non of them is detected.
- Only process one record per call.

Result:

OpenSslEngine behaves like stated in the javadocs of SSLEngine.

Modifications:

Not use InternalThreadLocalMap in places where the code-path will likely be executed from outside the EventLoop.

0b7bf49c16 Convert X509TrustManager into X509ExtendedTrustManager for Java 7+
Motivation:

Since Java 7, X509TrustManager implementation is wrapped by a JDK class
called AbstractTrustManagerWrapper, which performs an additional
certificate validation for Socket or SSLEngine-backed connections.

This makes the TrustManager implementations provided by
InsecureTrustManagerFactory and FingerprintTrustManagerFactory not
insecure enough, where their certificate validation fails even when it
should pass.

Modifications:

- Add X509TrustManagerWrapper which adapts an X509TrustManager into an
  X509ExtendedTrustManager
- Make SimpleTrustManagerFactory wrap an X509TrustManager with
  X509TrustManagerWrapper is the provided TrustManager does not extend
  X509ExtendedTrustManager

Result:

- InsecureTrustManagerFactory and FingerprintTrustManagerFactory are now
  insecure as expected.

3a8b8c9219 Consolidate flushes even when no read in progress
Motivation:

Currently FlushConsolidationHandler only consolidates if a read loop is
active for a Channel, otherwise each writeAndFlush(...) call will still
be flushed individually. When these calls are close enough, it can be
beneficial to consolidate them even outside of a read loop.

Modifications:

When we allow a flush to "go through", don't perform it immediately, but
submit it on the channel's executor. Under high pressure, this gives
other writes a chance to enqueue before the task gets executed, and so
we flush multiple writes at once.

Result:

Lower CPU usage and less context switching.

Motivation:
IdleStateHandler has a number of volatile member variables which are only accessed from the EventLoop thread. These do not have to be volatile. The accessibility of these member variables are not consistent between private and package private. The state variable can also use a byte instead of an int.

Modifications:
- Remove volatile from member variables
- Change access to private for member variables
- Change state from int to byte

8566fd1019 Add startTls parameter to SslContextBuilder
Motivation:

There is an incoherence in terms of API when one wants to use
startTls: without startTls one can use the SslContextBuilder's
method newHandler, but with startTls, the developper is forced
to call directly the SslHandler constructor.

Modifications:

Introduce startTls as a SslContextBuilder parameter as well as a
member in SslContext (and thus Jdk and OpenSsl implementations!).
Always use this information to call the SslHandler constructor.
Use false by default, in particular in deprecated constructors of
the SSL implementations.
The client Context use false by default

Results:

Fixes #5170 and more generally homogenise the API so that
everything can be done via SslContextBuilder.

b604a22395 Expose the ChannelHandlerContext from SniHandler's select() step to the user.
Motivation

I'm looking to harden our SSL impl. a little bit and add some guards agaist certain types of abuse. One can think of invalid hostname strings in the SNI extenstion or invalid SNI handshakes altogether. This will require measuring, velocity tracking and other things.

Modifications

Adding a protected `lookup(ctx, hostname)` method that is called from SniHandler's `select(...)` method which users can override and implement custom behaviour. The default implementation will simply call the AsyncMapper.

Result

It's possible to get a hold onto the ChannelHandlerContext. Users can override that method and do something with it right there or they can delegate it to something else. SniHandler is happy as long as a `Future<SslContext>` is being returned.

f97866dbc6 Expose SniHandler's replaceHandler() so that users can implement custom behavior.
Motivation

The SniHandler is currently hiding its replaceHandler() method and everything that comes with it. The user has no easy way of getting a hold onto the SslContext for the purpose of reference counting for example. The SniHandler does have getter methods for the SslContext and hostname but they're not very practical or useful. For one the SniHandler will remove itself from the pipeline and we'd have to track a reference of it externally and as we saw in #5745 it'll possibly leave its internal "selection" object with the "EMPTY_SELECTION" value (i.e. we've just lost track of the SslContext).

Modifications

Expose replaceHandler() and allow the user to override it and get a hold onto the hostname, SslContext and SslHandler that will replace the SniHandler.

Result

It's possible to get a hold onto the SslContext, the hostname and the SslHandler that is about to replace the SniHandler. Users can add additional behavior.

acb40a87c3 SniHandler reference count leak if pipeline replace fails
Motivation:
The SniHandler attempts to generate a new SslHandler from the selected SslContext in a and insert that SslHandler into the pipeline. However if the underlying channel has been closed or the pipeline has been modified the pipeline.replace(..) operation may fail. Creating the SslHandler may also create a SSLEngine which is of type ReferenceCounted. The SslHandler states that if it is not inserted into a pipeline that it will not take reference count ownership of the SSLEngine. Under these conditions we will leak the SSLEngine if it is reference counted.

Modifications:
- If the pipeline.replace(..) operation fails we should release the SSLEngine object.

Result:

Motivation:

When SslHandler.close(...) is called (as part of Channel.close()). it will also try to flush pending messages. This may fail for various reasons, but we still should propergate the close operation

Modifications:

- Ensure flush(...) itself will not throw an Exception if we was able to at least fail one pending promise (which should always be the case).
- If flush(...) fails as part of close ensure we still close the channel and then rethrow.

Result:

No more lost close operations possible if an exception is thrown during close

7d774584c8 OpenSslEngine with no finalizer
Motivation:
OpenSslEngine and OpenSslContext currently rely on finalizers to ensure that native resources are cleaned up. Finalizers require the GC to do extra work, and this extra work can be avoided if the user instead takes responsibility of releasing the native resources.

Modifications:
- Make a base class for OpenSslENgine and OpenSslContext which does not have a finalizer but instead implements ReferenceCounted. If this engine is inserted into the pipeline it will be released by the SslHandler
- Add a new SslProvider which can be used to enable this new feature

cebf255951 FlushConsolidationHandler remove conditional
Motivation:
FlushConsolidationHandler#flushIfNeeded has a conditional which is fixed based upon code path. This conditional can be removed and instead just manually set in each fixed code path.

Modifications:
- Remove boolean parameter on FlushConsolidationHandler#flushIfNeeded and set readInprogess to false manually when necessary

Result:
Less conditionals in FlushConsolidationHandler

2ce1d29d4d Elliminated some buggy behavior when using a KeyManagerFactory with OpenSslServerContext.
Motivation:

PR #5493 added support for KeyManagerFactories when using the OpenSsl context. This commit corrects a bug causing a NullPointerException that occurs when using a KeyManagerFactory without a certificate chain and private key.

Modifications:

Removes assertNotNull() assertions which were causing a certificate chain and private key to be required even when using a KeyManagerFactory. Also removed a redundant call to buildKeyManagerFactory() which was also causing a exception when a KeyManagerFactory is provided but a certificate chain and private key is not.

Result:

A KeyManagerFactory can now be used in the OpenSslServerContext without an independent certificate chain and private key.

e3c8a92499 Add FlushConsolidationHandler which consolidates flush operations as these are expensive
Motivation:

Calling flush() and writeAndFlush(...) are expensive operations in the sense as both will produce a write(...) or writev(...) system call if there are any pending writes in the ChannelOutboundBuffer. Often we can consolidate multiple flush operations into one if currently a read loop is active for a Channel, as we can just flush when channelReadComplete is triggered. Consolidating flushes can give a huge performance win depending on how often is flush is called. The only "downside" may be a bit higher latency in the case of where only one flush is triggered by the user.

Modifications:

Add a FlushConsolidationHandler which will consolidate flushes and so improve the throughput.

Result:

Better performance (throughput). This is especially true for protocols that use some sort of PIPELINING.

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.

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.

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

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.

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

Result:

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.

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

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.

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.

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.

Modifications:

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.

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.

Result:

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

Modifications:

- Upgrade to netty-tcnative-1.1.33.Fork13
- 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`.

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.

e1d34ef05d SslHandler should call beginHanshake once for the initial handshake
Motivation:

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+.

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.

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.

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)

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:

Correct and consistent behavior.

4aa19a09bd Implement SSLSession.invalidate() and isValid() for OpenSSLEngine.
Motivation:

The SSLSession allows to invalidate a SSLSession and so disallow resume of a session. We should support this for OpenSSLEngine as well.

Modifications:

- Correctly implement SSLSession.isValid() and invalidate() in OpenSSLEngine
- Add unit test.

Result:

Invalidate of SSL sessions is supported when using OpenSSL now.

66c3c58d3e Reduce object creation for for unwrap/wrap if no ByteBuffer[] is used.
Motivation:

Often unwrap(...), wrap(...) is used with a single ByteBuffer and not with a ByteBuffer[]. We should reduce the array creations in this case.

Modifications:

Reuse ByteBuffer[1] for dst/src ByteBuffer.

Result:

Less object creation and so less GC

dc6cb7545b Lazy compute SSLSession creation time.
Motivation:

As a SSL session may be created later at some time we should compute the creation time in a lazy fashion.

Modifications:

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.

179cd9a4a1 Correctly update internal handshake state on beginHandshake()
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.

Result:

Correctly handle OpenSslEngine.beginHandshake()

2766fc49e2 Expose new way of setting session keys
Motivation:

We should provide a better way to set session keys that not use the deprecated method of netty-tcnative.

Modifications:

- Add OpenSslSessionTicketKey
- Expose new method on OpenSslServerContext and deprecate the old method.

Result:

Easier to use and can remove the deprecated method later on.

Motivation:

The latest netty-tcnative fixes a bug in determining the version of the runtime openssl lib.  It also publishes an artificact with the classifier linux-<arch>-fedora for fedora-based systems.

Modifications:

Modified the build files to use the "-fedora" classifier when appropriate for tcnative. Care is taken, however, to not change the classifier for the native epoll transport.

Result:

Netty is updated the the new shiny netty-tcnative.

30b30f77c6 Support SSLSession.getLocalCertificates() and getLocalPrincipal() when using OpenSSL
Motivation:

SSLSession.getLocalCertificates() and getLocalPrincipal() was not supported when using OpenSSL, which can produce problems when switch from JDK to OpenSSL impl.

Modifications:

Implement SSLSession.getLocalCertificates() and getLocalPrincipal() for OpenSslEngine.

Result:

More consistent behaving between JDK and OpenSSL based SSLEngine.

- Correctly throw SSLPeerUnverifiedException
- Add test for it.

Result:

Correctly behave like descripted in javadocs.

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

5ac84760c4 Allow to create SslContext from existing PrivateKey / X509Certificate
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.

Result:

Creating of SslContext is possible with PrivateKay/X509Certificate

ecc01da9dd [#3968] Disallow pass-through of non ByteBufs in SslHandler
Motivation:

We pass-through non ByteBuf when SslHandler.write(...) is called which can lead to have unencrypted data to be send (like for example if a FileRegion is written).

Modifications:

- Fail ChannelPromise with UnsupportedMessageException if a non ByteBuf is written.

Result:

Only allow ByteBuf to be written when using SslHandler.

9660e2f6a9 Better handling of BUFFER_OVERFLOW when unwrap data.
Motivation:

When we detect a BUFFER_OVERFLOW we should just forward the already produced data and allocate a new buffer and NOT do any extra memory copies while trying to expand the buffer.

Modifications:

When a BUFFER_OVERFLOW is returned and some data was produced just fire this data through the pipeline and allocate a new buffer to read again.

Result:

Less memorycopies and so better performance.

8d1c6ebf71 Only do priming read if there is no space in dsts buffers.
Motivation:

A SSL_read is needed to ensure the bio buffer is flushed, for this we did a priming read. This can be removed in many cases. Also ensure we always fill as much as possible in the destination buffers.

Modifications:

- Only do priming read if capacity of all dsts buffers is zero
- Always produce as must data as possible in the dsts buffers.

Result:

Faster code.

18356911ab Stop calling BIO_write once internal buffer is full.
Motivation:

Previous we called BIO_write until either everything was written into it or it returned an error, which meant that the buffer is full. This then needed a ERR_clear_error() call which is expensive.

Modifications:

Break out of writing loop once we detect that not everything was written and so the buffer is full.

Result:

Less overhead when writing more data then the internal buffer can take.
2015-07-08 08:39:21 +02:00
Norman Maurer
a9d2b5cef0 Skip empty buffers and not pass these to BIO_write
Motivation:

When BIO_write is called with an empty buffer it will return 0 for which we call ERR_clear_error(). This is not neccessary as we should just skip these buffers. This eliminates a lot of overhead.

Modifications:

Skip empty src buffers when call unwrap(...).

Result:

Less overhead for unwrap(...) when called with empty buffers.

0f95b85ec2 Ensure OpenSslSession informations can be retrieved even after shutdown
Motivation:

If a user tries to access various informations on the OpenSslSession after the SSLEngine was closed it will not work if these were not accessed before as we lazy init most of them.

Modifications:

Directly populate the whole OpenSslSession once the handshake is complete and before the user is notified about it.

Result:

OpenSslSession informations are avaible until it is GC'ed.

bad8e0d6ab Correctly handle errors when using OpenSSL
Motivation:

We used ERR_get_error() to detect errors and missed to handle different errors. Also we missed to clear the error queue for a thread before invoke SSL operations,
this could lead to detecting errors on different OpenSslEngines then the one in which the error actual happened.

Modifications:

Explicit handle errors via SSL.get_error and clear the error code before SSL operations.

Result:

Correctly handle errors and no false-positives in different OpenSslEngines then the one which detected an error.

Motivation:

SpdyOrHttpChooser and Http2OrHttpChooser duplicate fair amount code with each other.

Modification:

- Replace SpdyOrHttpChooser and Http2OrHttpChooser with ApplicationProtocolNegotiationHandler
- Add ApplicationProtocolNames to define the known application-level protocol names

- Less code duplication
- A user can perform dynamic pipeline configuration that follows ALPN/NPN for any protocols.

afb46b926f Improve the API design of Http2OrHttpChooser and SpdyOrHttpChooser
Related: #3641 and #3813

Motivation:

When setting up an HTTP/1 or HTTP/2 (or SPDY) pipeline, a user usually
ends up with adding arbitrary set of handlers.

Http2OrHttpChooser and SpdyOrHttpChooser have two abstract methods
(create*Handler()) that expect a user to return a single handler, and
also have add*Handlers() methods that add the handler returned by
create*Handler() to the pipeline as well as the pre-defined set of
handlers.

The problem is, some users (read: I) don't need all of them or the
user wants to add more than one handler. For example, take a look at
io.netty.example.http2.tiles.Http2OrHttpHandler, which works around
this issue by overriding addHttp2Handlers() and making
createHttp2RequestHandler() a no-op.

Modifications:

- Replace add*Handlers() and create*Handler() with configure*()
- Rename getProtocol() to selectProtocol() to make what it does clear
- Provide the default implementation of selectProtocol()
- Remove SelectedProtocol.UNKNOWN and use null instead, because
  'UNKNOWN' is not a protocol
- Proper exception handling in the *OrHttpChooser so that the
  exception is logged and the connection is closed when failed to
  select a protocol
- Make SpdyClient example always use SSL. It was always using SSL
  anyway.
- Implement SslHandshakeCompletionEvent.toString() for debuggability
- Remove an orphaned class: JettyNpnSslSession
- Add SslHandler.applicationProtocol() to get the name of the
  application protocol
  - SSLSession.getProtocol() now returns transport-layer protocol name
    only, so that it conforms to its contract.

Result:

- *OrHttpChooser have better API.
- *OrHttpChooser handle protocol selection failure properly.
- SSLSession.getProtocol() now conforms to its contract.
- SpdyClient example works with SpdyServer example out of the box

bac2e3a6d2 Reduce calls to System.nanoTime() and object creation in IdleStateHandler. Related to [#3808]
Motivation:

Calling System.nanoTime() for each channelRead(...) is very expensive. See [#3808] for more detailed description.
Also we always do extra work for each write and read even if read or write idle states should not be handled.

Modifications:

- Move System.nanoTime() call to channelReadComplete(...).
- Reuse ChannelFutureListener for writes
- Only add ChannelFutureListener to writes if write and all idle states should be handled.
- Only call System.nanoTime() for reads if idle state events for read and all states should be handled.

Result:

Less overhead when using the IdleStateHandler.

Correctly only call TurstManagerFactory.init() if trustCertcChainFail is not null.

Result:

Correct behavior.

d5f1dc66aa Consistent use of SSLHandshakeException for ALPN
Motiviation:
The OpenSSL engine uses SSLHandshakeException in the event of failures that occur during the handshake process. The alpn-boot project's getSSLException will also map the no_application_protocol to a SSLHandshakeException exception. We should be consistent and use SSLHandshakeException for handshake failure events.

Modifications:
-Update JdkAlpnSslEngine to propagate an SSLHandshakeException in the event of a failure.

Result:
Consistent usage of SSLHandshakeException during a handshake failure event.

f3dcad3230 Do not call System.nanoTime() in ReadTimeoutHandler.channelRead()
Motivation:

We mitigate callouts to System.nanoTime() in SingleThreadEventExecutor
as it is 'relatively expensive'. On a modern system, tak translates to
about 20ns per call. With channelReadComplete() we can side-step this in
channelRead().

Modifications:

Introduce a boolean flag, which indicates that a read batch is currently
on-going, which acts as a flush guard for lastReadTime. Update
lastReadTime in channelReadComplete() just before setting the flag to
false. We set the flag to true in channelRead().

The periodic task examines the flag, and if it observes it to be true,
it will reschedule the task for the full duration. If it observes as
false, it will read lastReadTime and adjust the delay accordingly.

Result:

ReadTimeoutHandler calls System.nanoTime() only once per read batch.

864f196c67 Add missing SslContextBuilder.forServer(KeyManagerFactory)
Motivation:

keyManager() is required on server-side, and so there is a forServer()
method for each override of keyManager(). However, one of the
forServer() overrides was missing, which meant that if you wanted to use
a KeyManagerFactory you were forced to provide garbage configuration
just to get past null checks.

Modifications:

Add missing override.

Result:

No hacks to use SslContextBuilder on server-side with KeyManagerFactory.

Modifications:

- Use a trySuccess() and tryFailure(...) to guard against race.

62057f73d6 Fix handling of non-auto read for ByteToMessageDecoder and SslHandler
Motivation:

Our automatically handling of non-auto-read failed because it not detected the need of calling read again by itself if nothing was decoded. Beside this handling of non-auto-read never worked for SslHandler as it always triggered a read even if it decoded a message and auto-read was false.

This fixes [#3529] and [#3587].

Modifications:

- Implement handling of calling read when nothing was decoded (with non-auto-read) to ByteToMessageDecoder again
- Correctly respect non-auto-read by SslHandler

Result:

No more stales and correctly respecting of non-auto-read by SslHandler.

4e70523edd The "null" ClassLoader is the bootstrap ClassLoader
Motivation:
Class.forName() documents that null will use bootstrap loader:
http://docs.oracle.com/javase/8/docs/api/java/lang/Class.html#forName-java.lang.String-boolean-java.lang.ClassLoader-

But the link between "null" and bootstrap loader is even more explicit
in ClassLoader's documentation:
http://docs.oracle.com/javase/8/docs/api/java/lang/ClassLoader.html#getParent--

The current code is trying to use the bootstrap loader but seems to have
not been aware of the meaning of null.

Modifications:
Use "null" as the class loader when we want to load classes in the
bootstrap loader.

Result:
More reliable ALPN/NPN loading and simpler code.

aebbb862ac Add support for ALPN when using openssl + NPN client mode and support for CipherSuiteFilter
Motivation:

To support HTTP2 we need APLN support. This was not provided before when using OpenSslEngine, so SSLEngine (JDK one) was the only bet.
Beside this CipherSuiteFilter was not supported

Modifications:

- Upgrade netty-tcnative and make use of new features to support ALPN and NPN in server and client mode.
- Guard against segfaults after the ssl pointer is freed
- support correctly different failure behaviours
- add support for CipherSuiteFilter

Result:

Be able to use OpenSslEngine for ALPN / NPN for server and client.

190cbf55e4 Fix incorrect null value check in TrafficCounter
In TrafficCounter, a recent change makes the contract of the API (the
constructor) wrong and lead to issue with GlobalChannelTrafficCounter
where executor must be null.

Motivation:
TrafficCounter executor argument in constructor might be null, as
explained in the API, for some particular cases where no executor are
needed (relevant tasks being taken by the caller as in
GlobalChannelTrafficCounter).
A null pointer exception is raised while it should not since it is
legal.

Modifications:
Remove the 2 null checking for this particular attribute.
Note that when null, the attribute is not reached nor used (a null
checking condition later on is applied).

Result:
No more null exception raized while it should not.

This shall be made also to 4.0, 4.1 (present) and master. 3.10 is not
concerned.

f4e527c64d Don't trigger IOException at ChunkedStream.isEndOfInput()
Related: #3368

Motivation:

ChunkedWriteHandler checks if the return value of
ChunkedInput.isEndOfInput() after calling ChunkedInput.close().

This makes ChunkedStream.isEndOfInput() trigger an IOException, which is
originally triggered by PushBackInputStream.read().

By contract, ChunkedInput.isEndOfInput() should not raise an IOException
even when the underlying stream is closed.

Modifications:

Add a boolean flag that keeps track of whether the underlying stream has
been closed or not, so that ChunkedStream.isEndOfInput() does not
propagate the IOException from PushBackInputStream.

a97e413a65 Ensure server preference order in ALPN
Motivation:
With the current implementation the client protocol preference list
takes precedence over the one of the server, since the select method
will return the first item, in the client list, that matches any of the
protocols supported by the server. This violates the recommendation of
http://tools.ietf.org/html/rfc7301#section-3.2.

It will also fail with the current implementation of Chrome, which
sends back Extension application_layer_protocol_negotiation, protocols:
[http/1.1, spdy/3.1, h2-14]

Modifications:
Changed the protocol negotiator to prefer server’s list. Added a test
case that demonstrates the issue and that is fixed with the
modifications of this commit.

Result:
Server’s preference list is used.

8c135cdd55 Add a new constructor without handler parameter to TrafficCounter
Related: #3476

Motivation:

Some users use TrafficCounter for other uses than we originally
intended, such as implementing their own traffic shaper.  In such a
case, a user does not want to specify an AbstractTrafficShapingHandler.

Modifications:

- Add a new constructor that does not require an
  AbstractTrafficShapingHandler, so that a user can use it without it.
- Simplify TrafficMonitoringTask
- Javadoc cleanup

Result:

We open the possibility of using TrafficCounter for other purposes than
just using it with AbstractTrafficShapingHandler.  Eventually, we could
generalize it a little bit more, so that we can potentially use it for
other uses.

1bb818bb59 Reduce memory copies when using OpenSslEngine with SslHandler
Motivation:

When using OpenSslEngine with the SslHandler it is possible to reduce memory copies by unwrap(...) multiple ByteBuffers at the same time. This way we can eliminate a memory copy that is needed otherwise to cumulate partial received data.

Modifications:

- Add OpenSslEngine.unwrap(ByteBuffer[],...) method that can be used to unwrap multiple src ByteBuffer a the same time
- Use a CompositeByteBuffer in SslHandler for inbound data so we not need to memory copy
- Add OpenSslEngine.unwrap(ByteBuffer[],...) in SslHandler if OpenSslEngine is used and the inbound ByteBuf is backed by more then one ByteBuffer
- Reduce object allocation

Motivation:

Currently when there are bytes left in the cumulation buffer we do a byte copy to produce the input buffer for the decode method. This can put quite some overhead on the impl.

Modification:

- Use a CompositeByteBuf to eliminate the byte copy.
- Allow to specify if a CompositeBytebug should be used or not as some handlers can only act on one ByteBuffer in an efficient way (like SslHandler :( ).

2681112080 Fix big transfer and Write traffic shaping issues
Motivation:

Several issues were shown by various ticket (#2900 #2956).
Also use the improvement on writability user management from #3036.
And finally add a mixte handler, both for Global and Channels, with
the advantages of being uniquely created and using less memory and
less shaping.

Issue #2900

When a huge amount of data are written, the current behavior of the
TrafficShaping handler is to limit the delay to 15s, whatever the delay
the previous write has. This is wrong, and when a huge amount of writes
are done in a short time, the traffic is not correctly shapened.

Moreover, there is a high risk of OOM if one is not using in his/her own
handler for instance ChannelFuture.addListener() to handle the write
bufferisation in the TrafficShapingHandler.

This fix use the "user-defined writability flags" from #3036 to
allow the TrafficShapingHandlers to "user-defined" managed writability
directly, as for reading, thus using the default isWritable() and
channelWritabilityChanged().
This allows for instance HttpChunkedInput to be fully compatible.

The "bandwidth" compute on write is only on "acquired" write orders, not
on "real" write orders, which is wrong from statistic point of view.

Issue #2956

When using GlobalTrafficShaping, every write (and read) are
synchronized, thus leading to a drop of performance.
ChannelTrafficShaping is not touched by this issue since synchronized is
then correct (handler is per channel, so the synchronized).

Modifications:
The current write delay computation takes into account the previous
write delay and time to check is the 15s delay (maxTime) is really
exceeded or not (using last scheduled write time). The algorithm is
simplified and in the same time more accurate.

This proposal uses the #3036 improvement on user-defined writability
flags.

When the real write occurs, the statistics are update accordingly on a
new attribute (getRealWriteThroughput()).

To limit the synchronisations, all synchronized on
GlobalTrafficShapingHandler on submitWrite were removed. They are
replaced with a lock per channel (since synchronization is still needed
to prevent unordered write per channel), as in the sendAllValid method
for the very same reason.
Also all synchronized on TrafficCounter on read/writeTimeToWait() are
removed as they are unnecessary since already locked before by the
caller.
Still the creation and remove operations on lock per channel (PerChannel
object) are synchronized to prevent concurrency issue on this critical
part, but then limited.

Additionnal changes:
1) Use System.nanoTime() instead of System.currentTimeMillis() and
minimize calls
2) Remove / 10 ° 10 since no more sleep usage
3) Use nanoTime instead of currentTime such that time spend is computed,
not real time clock. Therefore the "now" relative time (nanoTime based)
is passed on all sub methods.
4) Take care of removal of the handler to force write all pending writes
and release read too
8) Review Javadoc to explicit:

- recommandations to take into account isWritable

- recommandations to provide reasonable message size according to
traffic shaping limit

- explicit "best effort" traffic shaping behavior when changing
configuration dynamically

Add a MixteGlobalChannelTrafficShapingHandler which allows to use only one
handler for mixing Global and Channel TSH. I enables to save more memory and
tries to optimize the traffic among various channels.

Result:
The traffic shaping is more stable, even with a huge number of writes in
short time by taking into consideration last scheduled write time.

The current implementation of TrafficShapingHandler using user-defined
writability flags and default isWritable() and
fireChannelWritabilityChanged works as expected.

The statistics are more valuable (asked write vs real write).

The Global TrafficShapingHandler should now have less "global"
synchronization, hoping to the minimum, but still per Channel as needed.

The GlobalChannel TrafficShapingHandler allows to have only one handler for all channels while still offering per channel in addition to global traffic shaping.

And finally maintain backward compatibility.

5c57b5de5b Check for errors without object allocation
Motivation:

At the moment we use SSL.getLastError() in unwrap(...) to check for error. This is very inefficient as it creates a new String for each check and we also use a String.startsWith(...) to detect if there was an error we need to handle.

Modifications:

Use SSL.getLastErrorNumber() to detect if we need to handle an error, as this only returns a long and so no String creation happens. Also the detection is much cheaper as we can now only compare longs. Once an error is detected the lately SSL.getErrorString(long) is used to conver the error number to a String and include it in log and exception message.

Result:

Performance improvements in OpenSslEngine.unwrap(...) due less object allocation and also faster comparations.

87eca066da More complete OpenSslEngine SSLSession implementation
Motivation:

The current SSLSession implementation used by OpenSslEngine does not support various operations and so may not be a good replacement by the SSLEngine provided by the JDK implementation.

Modifications:

- Add SSLSession.getCreationTime()
- Add SSLSession.getLastAccessedTime()
- Add SSLSession.putValue(...), getValue(...), removeValue(...), getValueNames()
- Add correct SSLSession.getProtocol()
- Ensure OpenSSLEngine.getSession() is thread-safe
- Use optimized AtomicIntegerFieldUpdater when possible

Result:

More complete OpenSslEngine SSLSession implementation

682df517c9 Add OpenSslClientContext to allow creating SslEngine for client side
Motivation:

We only support openssl for server side at the moment but it would be also useful for client side.

Modification:

* Upgrade to new netty-tcnative snapshot to support client side openssl support
* Add OpenSslClientContext which can be used to create SslEngine for client side usage
* Factor out common logic between OpenSslClientContext and OpenSslServerContent into new abstract base class called OpenSslContext
* Correctly detect handshake failures as soon as possible
* Guard against segfault caused by multiple calls to destroyPools(). This can happen if OpenSslContext throws an exception in the constructor and the finalize() method is called later during GC

Result:

openssl can be used for client and servers now.

b7e82b2ccb Efficiently handle writing ( wrap(...) ) of CompositeByteBuf when using SslHandler
Motivation:

SslHandler.wrap(...) does a poor job when handling CompositeByteBuf as it always call ByteBuf.nioBuffer() which will do a memory copy when a CompositeByteBuf is used that is backed by multiple ByteBuf.

Modifications:

- Use SslEngine.wrap(ByteBuffer[]...) to allow wrap CompositeByteBuf in an efficient manner
- Reduce object allocation in unwrapNonAppData(...)

Result:

Performance improvement when a CompositeByteBuf is written and the SslHandler is in the ChannelPipeline.

699e6e3b02 Fix memory leak in OpenSslEngine
Motivation:

When a remote peer did open a connection and only do the handshake without sending any data and then directly close the connection we did not call shutdown() in the OpenSslEngine. This leads to a native memory leak. Beside this it also was not fireed when a OpenSslEngine was created but never used.

Modifications:

- Make sure shutdown() is called in all cases when closeInbound() is called
- Call shutdown() also in the finalize() method to ensure we release native memory when the OpenSslEngine is GC'ed

Result:

No more memory leak when using OpenSslEngine

e72b2235fb Make sure to notify handshake success even if SSLEngine is closed
Related:

e9685ea45a

Motivation:

SslHandler.unwrap() does not evaluate the handshake status of
SSLEngine.unwrap() when the status of SSLEngine.unwrap() is CLOSED.

It is not correct because the status does not reflect the state of the
handshake currently in progress, accoding to the API documentation of
SSLEngineResult.Status.

Also, sslCloseFuture can be notified earlier than handshake notification
because we call sslCloseFuture.trySuccess() before evaluating handshake
status.

Modifications:

- Notify sslCloseFuture after the unwrap loop is finished
- Add more assertions to SocketSslEchoTest

Result:

Potentially fix the regression caused by:

d5a24d4f6c Make SslHandler work when autoRead is turned off
Related: #2958

Motivation:

SslHandler currently does not issue a read() request when it is
handshaking. It makes a connection with autoRead off stall, because a
user's read() request can be used to read the handshake response which
is invisible to the user.

Modifications:

- SslHandler now issues a read() request when:
  - the current handshake is in progress and channelReadComplete() is
    invoked
  - the current handshake is complete and a user issued a read() request
    during handshake
- Rename flushedBeforeHandshakeDone to flushedBeforeHandshake for
  consistency with the new variable 'readDuringHandshake'

Result:

SslHandler should work regardless whether autoRead is on or off.

Related: #3125

Motivation:

We did not expose a way to initiate TLS renegotiation and to get

Modifications:

- Add SslHandler.renegotiate() so that a user can initiate TLS
  renegotiation and get the future that's notified on completion
- Make SslHandler.handshakeFuture() return the future for the most
  recent handshake so that a user can get the future of the last
  renegotiation
- Add the test for renegotiation to SocketSslEchoTest

Result:

Both client-initiated and server-initiated renegotiations are now

9ff234abed Call ctx.flush() at least once in ChunkedWriteHandler.flush()
Related: #3219

Motivation:

ChunkedWriteHandler.flush() does not call ctx.flush() when channel is
not writable. This can be a problem when other handler / non-Netty
thread writes messages simultaneously, because
ChunkedWriteHandler.flush() might have no chance to observe
channel.isWritable() returns true and thus the channel is never flushed.

Modifications:

- Ensure that ChunkedWriteHandler.flush() calls ctx.flush() at least
  once.

Result:

A stall connection issue, that occurs when certain combination of
handlers exist in a pipeline, has been fixed. (e.g. SslHandler and
ChunkedWriteHandler)

Modifications:

- Replace mockito-all with mockito-core to avoid pulling in outdated
  jUnit and Hamcrest
- Exclude junit-dep when pulling in jmock-junit4, because it pulls an
  outdated Hamcrest version
- Pull in the hamcrest-library version used by jUnit explicitly

8f77c80795 Added support for SSL Server Name Indication.
Motivation:

When we need to host multiple server name with a single IP, it requires
the server to support Server Name Indication extension to serve clients
with proper certificate. So the SniHandler will host multiple
SslContext(s) and append SslHandler for requested hostname.

Modification:

* Added SniHandler to host multiple certifications in a single server
* Test case

Result:

User could use SniHandler to host multiple certifcates at a time.
It's server-side only.

d33a80da26 Use Triple DES in JdkSslContext cipher suite list.
Motivation:

JdkSslContext used SSL_RSA_WITH_DES_CBC_SHA in its cipher suite list.
OpenSslServerContext used DES-CBC3-SHA in the same place in its cipher suite
list, which is equivalent to SSL_RSA_WITH_3DES_EDE_CBC_SHA.

This means the lists were out of sync. Furthermore, using
SSL_RSA_WITH_DES_CBC_SHA is not desirable as it uses DES, a weak cipher. Triple
DES should be used instead.

Modifications:

Replace SSL_RSA_WITH_DES_CBC_SHA with SSL_RSA_WITH_3DES_EDE_CBC_SHA in
JdkSslContext.

Result:

The JdkSslContext and OpenSslServerContext cipher suite lists are now in sync.
Triple DES is used instead of DES, which is stronger.

35db3c6710 Small performance improvements
Motivation:

Found performance issues via FindBugs and PMD.

Modifications:

- Removed unnecessary boxing/unboxing operations in DefaultTextHeaders.convertToInt(CharSequence) and DefaultTextHeaders.convertToLong(CharSequence). A boxed primitive is created from a string, just to extract the unboxed primitive value.
- Added a static modifier for DefaultHttp2Connection.ParentChangedEvent class. This class is an inner class, but does not use its embedded reference to the object which created it. This reference makes the instances of the class larger, and may keep the reference to the creator object alive longer than necessary.
- Added a static compiled Pattern to avoid compile it each time it is used when we need to replace some part of authority.
- Improved using of StringBuilders.

Result:

ca29be5e77 Allow ChunkedInput to provide the progress of its transfer
Related issue: #2741 and #2151

Motivation:

There is no way for ChunkedWriteHandler to know the progress of the
transfer of a ChannelInput. Therefore, ChannelProgressiveFutureListener
cannot get exact information about the progress of the transfer.

If you add a few methods that optionally provides the transfer progress
to ChannelInput, it becomes possible for ChunkedWriteHandler to notify
ChannelProgressiveFutureListeners.

If the input has no definite length, we can still use the progress so
far, and consider the length of the input as 'undefined'.

Modifications:

- Add ChunkedInput.progress() and ChunkedInput.length()
- Modify ChunkedWriteHandler to use progress() and length() to notify
  the transfer progress

Result:

ChunkedWriteHandler now notifies ChannelProgressiveFutureListener.

bc1379d19d [#2721] Improve Traffic Shaping handler
Motivation:
Currently Traffic Shaping is using 1 timer only and could lead to
"partial" wrong bandwidth computation when "short" time occurs between
adding used bytes and when the TrafficCounter updates itself and finally
when the traffic is computed.
Indeed, the TrafficCounter is updated every x delay and it is at the
same time saved into "lastXxxxBytes" and set to 0. Therefore, when one
request the counter, it first updates the TrafficCounter with the added
used bytes. If this value is set just before the TrafficCounter is
updated, then the bandwidth computation will use the TrafficCounter with
a "0" value (this value being reset once the delay occurs). Therefore,
the traffic shaping computation is wrong in rare cases.

Secondly the traffic shapping should avoid if possible the "Timeout"
effect by not stopping reading or writing more than a maxTime, this
maxTime being less than the TimeOut limit.

Thirdly the traffic shapping in read had an issue since the readOp
was not set but should, turning in no read blocking from socket
point of view.

Modifications:
The TrafficCounter has 2 new methods that compute the time to wait
according to read or write) using in priority the currentXxxxBytes (as
before), but could used (if current is at 0) the lastXxxxxBytes, and
therefore having more chance to take into account the real traffic.

Moreover the Handler could change the default "max time to wait", which
is by default set to half of "standard" Time Out (30s:2 = 15s).

Finally we add the setAutoRead(boolean) accordingly to the situation,
as proposed in #2696 (this pull request is in error for unknown reason).

Result:
The Traffic Shaping is better take into account (no 0 value when it
shouldn't) and it tries to not block traffic more than Time Out event.

Moreover the read is really stopped from socket point of view.

This version is similar to #2388 and #2450.
This version is for V4.1, and includes the #2696 pull request
to ease the merge process.
It is compatible with master too.

Including also #2748

The test minimizes time check by reducing to 66ms steps (55s).

02e7e53cbb [#2752] Add PendingWriteQueue for queue up writes
Motivation:

Sometimes ChannelHandler need to queue writes to some point and then process these. We currently have no datastructure for this so the user will use an Queue or something like this. The problem is with this Channel.isWritable() will not work as expected and so the user risk to write to fast. That's exactly what happened in our SslHandler. For this purpose we need to add a special datastructure which will also take care of update the Channel and so be sure that Channel.isWritable() works as expected.

Modifications:

- Add PendingWriteQueue which can be used for this purpose
- Make use of PendingWriteQueue in SslHandler

Result:

It is now possible to queue writes in a ChannelHandler and still have Channel.isWritable() working as expected. This also fixes #2752.

c85319213a [#2675] Replace synchronization performed on util.concurrent instance in TrafficCounter
Motivation:

Message from FindBugs:
This method performs synchronization an object that is an instance of a class from the java.util.concurrent package (or its subclasses). Instances of these classes have their own concurrency control mechanisms that are orthogonal to the synchronization provided by the Java keyword synchronized. For example, synchronizing on an AtomicBoolean will not prevent other threads from modifying the AtomicBoolean.
Such code may be correct, but should be carefully reviewed and documented, and may confuse people who have to maintain the code at a later date.

Modification:

Use synchronized(this)

Result:

b83df4c6b3 Fix NPE problems
Motivation:

Now Netty has a few problems with null values.

Modifications:

- Check HAProxyProxiedProtocol in HAProxyMessage constructor and throw NPE if it is null.
If HAProxyProxiedProtocol is null we will set AddressFamily as null. So we will get NPE inside checkAddress(String, AddressFamily) and it won't be easy to understand why addrFamily is null.
- Check File in DiskFileUpload.toString().
If File is null we will get NPE when calling toString() method.
- Check Result<String> in MqttDecoder.decodeConnectionPayload(...).
If !mqttConnectVariableHeader.isWillFlag() || !mqttConnectVariableHeader.hasUserName() || !mqttConnectVariableHeader.hasPassword() we will get NPE when we will try to create new instance of MqttConnectPayload.
- Check Unsafe before calling unsafe.getClass() in PlatformDependent0 static block.
- Removed unnecessary null check in WebSocket08FrameEncoder.encode(...).
Because msg.content() can not return null.
- Removed unnecessary null check in DefaultStompFrame(StompCommand) constructor.
Because we have this check in the super class.
- Removed unnecessary null checks in ConcurrentHashMapV8.removeTreeNode(TreeNode<K,V>).
- Removed unnecessary null check in OioDatagramChannel.doReadMessages(List<Object>).
Because tmpPacket.getSocketAddress() always returns new SocketAddress instance.
- Removed unnecessary null check in OioServerSocketChannel.doReadMessages(List<Object>).
Because socket.accept() always returns new Socket instance.
- Pass Unpooled.buffer(0) instead of null inside CloseWebSocketFrame(boolean, int) constructor.
If we will pass null we will get NPE in super class constructor.
- Added throw new IllegalStateException in GlobalEventExecutor.awaitInactivity(long, TimeUnit) if it will be called before GlobalEventExecutor.execute(Runnable).
Because now we will get NPE. IllegalStateException will be better in this case.
- Fixed null check in OpenSslServerContext.setTicketKeys(byte[]).
Now we throw new NPE if byte[] is not null.

Result:

Added new null checks when it is necessary, removed unnecessary null checks and fixed some NPE problems.

217fb0de05 [#2618] Introduce ChannelPromise.unvoid() and ChannelFuture.isVoid()
Motivation:

There is no way for a ChannelHandler to check if the passed in ChannelPromise for a write(...) call is a VoidChannelPromise. This is a problem as some handlers need to add listeners to the ChannelPromise which is not possible in the case of a VoidChannelPromise.

Modification:

- Introduce ChannelFuture.isVoid() which will return true if it is not possible to add listeners or wait on the result.
- Add ChannelPromise.unvoid() which allows to create a ChannelFuture out of a void ChannelFuture which supports all the operations.

Result:

It's now easy to write ChannelHandler implementations which also works when a void ChannelPromise is used.

085a61a310 Refactor FastThreadLocal to simplify TLV management
Motivation:

When Netty runs in a managed environment such as web application server,
Netty needs to provide an explicit way to remove the thread-local
variables it created to prevent class loader leaks.

FastThreadLocal uses different execution paths for storing a
thread-local variable depending on the type of the current thread.
It increases the complexity of thread-local removal.

Modifications:

- Moved FastThreadLocal and FastThreadLocalThread out of the internal
  package so that a user can use it.
- FastThreadLocal now keeps track of all thread local variables it has
  initialized, and calling FastThreadLocal.removeAll() will remove all
  thread-local variables of the caller thread.
- Added FastThreadLocal.size() for diagnostics and tests
- Introduce InternalThreadLocalMap which is a mixture of hard-wired
  thread local variable fields and extensible indexed variables
- FastThreadLocal now uses InternalThreadLocalMap to implement a
  thread-local variable.
- Added ThreadDeathWatcher.unwatch() so that PooledByteBufAllocator
  tells it to stop watching when its thread-local cache has been freed
  by FastThreadLocal.removeAll().
- Added FastThreadLocalTest to ensure that removeAll() works
- Added microbenchmark for FastThreadLocal and JDK ThreadLocal
- Upgraded to JMH 0.9

Result:

- A user can remove all thread-local variables Netty created, as long as
  he or she did not exit from the current thread. (Note that there's no
  way to remove a thread-local variable from outside of the thread.)
- FastThreadLocal exposes more useful operations such as isSet() because
  we always implement a thread local variable via InternalThreadLocalMap
  instead of falling back to JDK ThreadLocal.
- FastThreadLocalBenchmark shows that this change improves the
  performance of FastThreadLocal even more.

ChannelTrafficShapingHandler may corrupt inbound data stream by
scheduling the fireChannelRead event.

Modification:
Always call fireChannelRead(...) and only suspend reads after it

Result:
No more data corruption

5ce410c69e Future compatibility with TLS ALPN
Motivation:

According to TLS ALPN draft-05, a client sends the list of the supported
protocols and a server responds with the selected protocol, which is
different from NPN.  Therefore, ApplicationProtocolSelector won't work
with ALPN

Modifications:

- Use Iterable<String> to list the supported protocols on the client
  side, rather than using ApplicationProtocolSelector
- Remove ApplicationProtocolSelector

Result:

Future compatibility with TLS ALPN

861ed1e7ad Add unified NextProtoNego extension support to SslContext
Motivation:

- OpenSslEngine and JDK SSLEngine (+ Jetty NPN) have different APIs to
  support NextProtoNego extension.
  - It is impossible to configure NPN with SslContext when the provider
    type is JDK.

Modification:

- Implement NextProtoNego extension by overriding the behavior of
  SSLSession.getProtocol() for both OpenSSLEngine and JDK SSLEngine.
  - SSLEngine.getProtocol() returns a string delimited by a colon (':')
    where the first component is the transport protosol (e.g. TLSv1.2)
    and the second component is the name of the application protocol
- Remove the direct reference of Jetty NPN classes from the examples
- Add SslContext.newApplicationProtocolSelector

Result:

- A user can now use both JDK SSLEngine and OpenSslEngine for NPN-based
  protocols such as HTTP2 and SPDY

4882377c27 Work around the JVM crash that occurs when cipher suite uses GCM
Motivation:

For an unknown reason, JVM of JDK8 crashes intermittently when
SslHandler feeds a direct buffer to SSLEngine.unwrap() *and* the current
cipher suite has GCM (Galois/Counter Mode) enabled.

Modifications:

Convert the inbound network buffer to a heap buffer when the current
cipher suite is using GCM.

Result:

JVM does not crash anymore.

ae61b12b9e Reduce memory usage of SslHandler when OpenSslEngine is in use
Motivation:

JDK's SSLEngine.wrap() requires the output buffer to be always as large as MAX_ENCRYPTED_PACKET_LENGTH even if the input buffer contains small number of bytes.  Our OpenSslEngine implementation does not have such wasteful behaviot.

Modifications:

If the current SSLEngine is OpenSslEngine, allocate as much as only needed.

Result:

Less peak memory usage.

9125060752 Optimize SslHandler in an OpenSslEngine-friendly way
Motivation:

Previous fix for the OpenSslEngine compatibility issue (#2216 and
18b0e95659) was to feed SSL records one by
one to OpenSslEngine.unwrap().  It is not optimal because it will result
in more JNI calls.

Modifications:

- Do not feed SSL records one by one.
- Feed as many records as possible up to MAX_ENCRYPTED_PACKET_LENGTH
- Deduplicate MAX_ENCRYPTED_PACKET_LENGTH definitions

Result:

- No allocation of intemediary arrays
- Reduced number of calls to SSLEngine and thus its underlying JNI calls
- A tad bit increase in throughput, probably reverting the tiny drop
  caused by 18b0e95659

b6c0c0c95f Add an OpenSslEngine and the universal API for enabling SSL
Motivation:

Some users already use an SSLEngine implementation in finagle-native. It
wraps OpenSSL to get higher SSL performance.  However, to take advantage
of it, finagle-native must be compiled manually, and it means we cannot
pull it in as a dependency and thus we cannot test our SslHandler
against the OpenSSL-based SSLEngine.  For an instance, we had #2216.

Because the construction procedures of JDK SSLEngine and OpenSslEngine
are very different from each other, we also need to provide a universal
way to enable SSL in a Netty application.

Modifications:

- Pull netty-tcnative in as an optional dependency.
  http://netty.io/wiki/forked-tomcat-native.html
- Backport NativeLibraryLoader from 4.0
- Move OpenSSL-based SSLEngine implementation into our code base.
  - Copied from finagle-native; originally written by @jpinner et al.
  - Overall cleanup by @trustin.
- Run all SslHandler tests with both default SSLEngine and OpenSslEngine
- Add a unified API for creating an SSL context
  - SslContext allows you to create a new SSLEngine or a new SslHandler
    with your PKCS#8 key and X.509 certificate chain.
  - Add JdkSslContext and its subclasses
  - Add OpenSslServerContext
- Add ApplicationProtocolSelector to ensure the future support for NPN
  (NextProtoNego) and ALPN (Application Layer Protocol Negotiation) on
  the client-side.
- Add SimpleTrustManagerFactory to help a user write a
  TrustManagerFactory easily, which should be useful for those who need
  to write an alternative verification mechanism. For example, we can
  use it to implement an unsafe TrustManagerFactory that accepts
  self-signed certificates for testing purposes.
- Add InsecureTrustManagerFactory and FingerprintTrustManager for quick
  and dirty testing
- Add SelfSignedCertificate class which generates a self-signed X.509
  certificate very easily.
- Update all our examples to use SslContext.newClient/ServerContext()
- SslHandler now logs the chosen cipher suite when handshake is
  finished.

Result:

- Cleaner unified API for configuring an SSL client and an SSL server
  regardless of its internal implementation.
- When native libraries are available, OpenSSL-based SSLEngine
  implementation is selected automatically to take advantage of its
  performance benefit.
- Examples take advantage of this modification and thus are cleaner.

Motivation:

As discussed in #2250, it will become much less complicated to implement
deregistration and reregistration of a channel once #2250 is resolved.
Therefore, there's no need to deprecate deregister() and
channelUnregistered().

Modification:

- Undeprecate deregister() and channelUnregistered()
- Remove SuppressWarnings annotations where applicable

af9ab8b370 Feed only a single SSL record to SSLEngine.unwrap()
Motivation:

Some SSLEngine implementations violate the contract and raises an
exception when SslHandler feeds an input buffer that contains multiple
SSL records to SSLEngine.unwrap(), while the expected behavior is to
decode the first record and return.

Modification:

- Modify SslHandler.decode() to keep the lengths of each record and feed
  SSLEngine.unwrap() record by record to work around the forementioned
  issue.
- Rename unwrap() to unwrapMultiple() and unwrapNonApp()
- Rename unwrap0() to unwrapSingle()

Result:

SslHandler now works OpenSSLEngine from finagle-native.  Performance
impact remains unnoticeable.  Slightly better readability. Fixes #2116.

e9161147a5 Work around an Android SSLEngine issue
Motivation:

Some Android SSLEngine implementations skip FINISHED handshake status
and go straightly into NOT_HANDSHAKING.  This behavior blocks SslHandler
from notifying its handshakeFuture, because we do the notification when
SSLEngine enters the FINISHED state.

Modification:

When the current handshake state is NOT_HANDSHAKING and the
handshakeFuture is not fulfilled yet, treat NOT_HANDSHAKING as FINISHED.

Better Android compatibility - fixes #1823

3eec26b0a2 [#2358] SslHandler.safeClose(...) may not notify the ChannelPromise
Motivation:
In SslHandler.safeClose(...) we attach a ChannelFutureListener to the flushFuture and will notify the ChannelPromise which was used for close(...) in it. The problem here is that we only call ChannelHandlerContext.close(ChannelPromise) if Channel.isActive() is true and otherwise not notify it at all. We should just call ChannelHandlerContext.close(ChannelPromise) in all cases.

Modifications:
Always call ChannelHandlerContext.close(ChannelPromise) in the ChannelFutureListeiner

Result:
ChannelPromise used for close the Channel is notified in all cases

cf9c1f946a Deleting redundant needsFlush boolean
Motivation:

In ChunkedWriteHandler, there is a redundant variable that servers
no purpose. It implies that under some conditions you might not want
to flush.

Modifications:

Removed the variable and the if condition that read it. The boolean
was always true so just removing the if statement was fine.

Result:

Slightly less misleading code.

cf275237c9 Overall clean-up of ipfilter package
Motivation:

Recently merged ipfilter package has the following problems:
* AbstractIpFilterHandler could be improved to support any SocketAddress types rather than only InetSocketAddress.
* AbstractIpFilterHandler can be removed immediately after decision is made rather than keeping the outcome of the decision as an attribute.
* AbstractIpFilterHandler doesn't have a hook for the accepted addresses.
* The hook method (reject()) needs to be named in line with other handler methods (i.e. channelRejected())
* IpFilterRuleHandler should allow accepting zero rules - it's particularly useful for machine-configured setup (i.e. specifying zero rules disables ipfilter).
* IpFilterRuleType.ALLOW/DENY should be ACCEPT/REJECT for consistency.

Modifications:

* AbstractIpFilterHandler has been renamed to AbstractRemoteAddressFilter and now uses type parameter.
* Added channelAccepted() and renamed reject() to channelRejected()
* Added ChannelHandlerContext as a parameter of accept() so that accept() can add a listener to the closeFuture() of the channel. This way, UniqueIpFilter continue working even if we remove the filtering handler early.
* Various renames
  * IpFilterRuleHandler -> RuleBasedIpFilter
  * UniqueIpFilterHandler -> UniqueIpFilter

Result:

* Much cleaner API with more extensibility

1884a5697c Avoid unnecessary IllegalStateException in ChunkedWriteHandler
Motivation:
ChunkedWriteHandler can sometimes fail to write the last chunk of a ChunkedInput due to an I/O error.  Subsequently, the ChunkedInput's associated promise is marked as failure and the connection is closed.  When the connection is closed, ChunkedWriteHandler attempts to clean up its message queue and to mark their promises as success or failure.  However, because the promise of the ChunkedInput, which was consumed completely yet failed to be written, is already marked as failure, the attempt to mark it as success fails, leading a WARN level log.

Modification:
Use trySuccess() instead of setSuccess() so that the attempt to mark a ChunkedInput as success does not raise an exception even if the promise is already done.

Result:
Fixes #2249
