Motivation:
In some of our tests we not correctly init the SSLEngine before trying to perform a handshake which can cause an IllegalStateException. While this not happened in previous java releases it does now on Java11 (which is "ok" as its even mentioned in the api docs). Beside this how we selected the ciphersuite to test renegotation was not 100 % safe.
Modifications:
- Correctly init SSLEngine before using it
- Correctly select ciphersuite before testing for renegotation.
Result:
More correct tests and also pass on next java11 EA release.
Motivation:
This reverts commit 4b728cd5bc as it was fixes in Java 11 ea+17.
Modification:
Revert previous added workaround as this is fixed in Java 11 now.
Result:
No more workaround for test included.
Motivation:
Epoll and Kqueue channels have internal state which forces
a single read operation after channel construction. This
violates the Channel#read() interface which indicates that
data shouldn't be delivered until this method is called.
The behavior is also inconsistent with the NIO transport.
Modifications:
- Epoll and Kqueue shouldn't unconditionally read upon
initialization, and instead should rely upon Channel#read()
or auto_read.
Result:
Epoll and Kqueue are more consistent with NIO.
Motivation:
Java11 disallow draining any remaining bytes from the socket if a write causes a connection reset. This should be completely safe to do. At the moment if a write is causing a connection-reset you basically loose all the pending bytes that are sitting on the socket and are waiting to be read.
This happens because SocketOutputStream.write(…) may call AbstractPlainSocketImpl.setConnectionReset(…). Once this method is called any read(…) call will just throw a SocketException without even attempt to read any remaining data.

- http://mail.openjdk.java.net/pipermail/net-dev/2018-May/011511.html
Modifications:
Tolarate if remaining bytes could not be read when using OIO.
Result:
Be able to build Netty and run testsuite while using Java11
Motivation:
We added a workaround for Java 11 as it not produced a connect-reset when SO_LINGER with 0 was set and NIO was used. This was fixed in the latest ea release of Java 11:
- http://hg.openjdk.java.net/jdk/jdk/rev/ea54197f4fe4
- https://bugs.openjdk.java.net/browse/JDK-8203059
Modifications:
Revert workaround.
Result:
Test that Java 11 behave the same way as earlier Java versions again.
Motivation:
Java 11 will be out soon, so we should be able to build (and run tests) netty.
Modifications:
- Add dependency that is needed till Java 11
- Adjust tests so these also pass on Java 11 (SocketChannelImpl.close() behavious a bit differently now).
Result:
Build also works (and tests pass) on Java 11.
Motivation:
Java 10 is out so we should be able to build netty with it (and run the tests).
Modifications:
- Update Mockito and JBoss Marshalling to support Java 10
- Fix unit test to not depend on specific cipher which is not present in Java 10 anymore
Result:
Netty builds (and runs all tests) when using Java 10
Motivation:
DatagramPacket.recipient() doesn't return the actual destination IP, but the IP the app is bound to.
Modification:
- IP_RECVORIGDSTADDR option is enabled for UDP sockets, which allows retrieval of ancillary information containing the original recipient.
- _recvFrom(...) function from transport-native-unix-common/src/main/c/netty_unix_socket.c is modified such that if IP_RECVORIGDSTADDR is set, recvmsg is used instead of recvfrom; enabling the retrieval of the original recipient.
- DatagramSocketAddress also contains a 'local' address, representing the recipient.
- EpollDatagramChannel is updated to return the retrieved recipient address instead of the address the channel is bound to.
Result:
Fixes#4950.
Motivation:
AbstractNioByteChannel will detect that the remote end of the socket has
been closed and propagate a user event through the pipeline. However if
the user has auto read on, or calls read again, we may propagate the
same user events again. If the underlying transport continuously
notifies us that there is read activity this will happen in a spin loop
which consumes unnecessary CPU.
Modifications:
- AbstractNioByteChannel's unsafe read() should check if the input side
of the socket has been shutdown before processing the event. This is
consistent with EPOLL and KQUEUE transports.
- add unit test with @normanmaurer's help, and make transports consistent with respect to user events
Result:
No more read spin loop in NIO when the channel is half closed.
Motivation:
We called the wrong super method in the test and also had a few unused imports.
Modifications:
Fix super method call and cleanup.
Result:
More correct test and cleanup.
Motivation:
b215794de3 recently introduced a change in behavior where writeSpinCount provided a limit for how many write operations were attempted per flush operation. However when the write quantum was meet the selector write flag was not cleared, and the channel unsafe flush0 method has an optimization which prematurely exits if the write flag is set. This may lead to no write progress being made under the following scenario:
- flush is called, but the socket can't accept all data, we set the write flag
- the selector wakes us up because the socket is writable, we write data and use the writeSpinCount quantum
- we then schedule a flush() on the EventLoop to execute later, however it the flush0 optimization prematurely exits because the write flag is still set
In this scenario the socket is still writable so the EventLoop may never notify us that the socket is writable, and therefore we may never attempt to flush data to the OS.
Modifications:
- When the writeSpinCount quantum is exceeded we should clear the selector write flag
Result:
Fixes https://github.com/netty/netty/issues/7729
Motivation:
We recently removed support for renegotiation, but there are still some hooks to attempt to allow remote initiated renegotiation to succeed. The remote initated renegotiation can be even more problematic from a security stand point and should also be removed.
Modifications:
- Remove state related to remote iniated renegotiation from OpenSslEngine
Result:
More renegotiation code removed from the OpenSslEngine code path.
Motivation:
IovArray implements MessageProcessor, and the processMessage method will continue to be called during iteration until it returns true. A recent commit b215794de3 changed the return value to only return true if any component of a CompositeByteBuf was added as a result of the method call. However this results in the iteration continuing, and potentially subsequent smaller buffers maybe added, which will result in out of order writes and generally corrupts data.
Modifications:
- IovArray#add should return false so that the MessageProcessor#processMessage will stop iterating.
Result:
Native transports which use IovArray will not corrupt data during gathering writes of CompositeByteBuf objects.
Motivation:
At the moment we use netty.io as BAD_HOST with an port that we know is timing out. This may change in the future so we should better use 198.51.100.254 which is specified as "for documentation only".
Modifications:
Replace netty.io with 198.51.100.254 in tests that depend on BAD_HOST.
Result:
More future proof code.
Motivation:
af2f343648 introduced a test-case which was flacky due of multiple problems:
- we called writeAndFlush(...) in channelRead(...) and assumed it will only be called once. This is true most of the times but it may be called multile times if the data is fragemented.
- we didnt guard against the possibility that channelRead(...) is called with an empty buffer
Modifications:
- Call writeAndFlush(...) in channelActive(...) so we are sure its only called once and close the channel once we wrote the data
- only compare the data after we received a close so we are sure there isnt anything extra received
- check for exception and if we catched one fail the test.
Result:
No flacky test anymore and easier to debug issues that accour because of a catched exception.
Motivation:
FileDescriptor#writev calls JNI code, and that JNI code dereferences a NULL pointer which crashes the application. This occurs when writing a single CompositeByteBuf object with more than one component.
Modifications:
- Initialize the iovec iterator properly to avoid the core dump
- Fix the array length calculation if we aren't able to fit all the ByteBuffer objects in the iovec array
Result:
No more core dump.
Motivation:
When SO_LINGER is used we run doClose() on the GlobalEventExecutor by default so we need to ensure we schedule all code that needs to be run on the EventLoop on the EventLoop in doClose. Beside this there are also threading issues when calling shutdownOutput(...)
Modifications:
- Schedule removal from EventLoop to the EventLoop
- Correctly handle shutdownOutput and shutdown in respect with threading-model
- Add unit tests
Result:
Fixes [#7159].
Motivation:
We recently saw an assertion failure when running DatagramUnicastTest.testSimpleSendWithConnect.
Modifications:
- Adding more debug infos
- Ensure we always correctly release the buffers.
Result:
More informations when tests fail.
Motivation:
If AutoClose is false and there is a IoException then AbstractChannel will not close the channel but instead just fail flushed element in the ChannelOutboundBuffer. AbstractChannel also notifies of writability changes, which may lead to an infinite loop if the peer has closed its read side of the socket because we will keep accepting more data but continuously fail because the peer isn't accepting writes.
Modifications:
- If the transport throws on a write we should acknowledge that the output side of the channel has been shutdown and cleanup. If the channel can't accept more data because it is full, and still healthy it is not expected to throw. However if the channel is not healthy it will throw and is not expected to accept any more writes. In this case we should shutdown the output for Channels that support this feature and otherwise just close.
- Connection-less protocols like UDP can remain the same because the channel may disconnected temporarily.
- Make sure AbstractUnsafe#shutdownOutput is called because the shutdown on the socket may throw an exception.
Result:
More correct handling of write failure when AutoClose is false.
Motivation:
SocketStringEchoTest has been observed to fail on CI servers, but the stack traces still indicate work was being done.
Modifications:
- Increase the test timeout
Result:
Tests have more time to complete, and hopefully less false positive test failures.
Motivation:
EpollDomainSocketGatheringWriteTest. testGatheringWriteBig takes on average about 20-25 seconds on the CI servers, but there is a 30 second timeout being applied which leads to what maybe false positive test failures.
Modifications:
- Increase the test timeout to 120 seconds globally and 60 seconds to wait for all writes per test
Result:
Higher timeout for potentially less false positive test failures.
Motivation:
SocketGatherWriteTest has been observed to fail and it has numerous issues which when resolved may help reduce the test failures.
Modifications:
- A volatile counter and a spin/sleep loop is used to trigger test termination. Incrementing a volatile is generally bad practice and can be avoided in this situation. This mechanism can be replaced by a promise. This mechanism should also trigger upon exception or channel inactive.
- The TestHandler maintains an internal buffer, but it is not released. We now only create a buffer on the server side and release it after comparing the expected results.
- The composite buffer creation logic can be simplified, also the existing composite buffer doesn't take into account the buffer's reader index when building buf2.
Result:
Cleaner test.
Motivation:
SocketStringEchoTest has been observed to fail and it has numerous issues which when resolved may help reduce the test failures.
Modifications:
- A volatile counter and a spin/sleep loop is used to trigger test termination. Incrementing a volatile is generally bad practice and can be avoided in this situation. This mechanism can be replaced by a promise. This mechanism should also trigger upon exception or channel inactive.
- Asserts are done in the Netty threads. Although these should result in a exceptionCaught the test may not observe these failures because it is spinning waiting for the count to reach the desired value.
Result:
Cleaner test.
Motivation:
We need to support SO_TIMEOUT for the OioDatagramChannel but we miss this atm as we not have special handling for it in the DatagramChannelConfig impl that we use. Because of this the following log lines showed up when running the testsuite:
20:31:26.299 [main] WARN io.netty.bootstrap.Bootstrap - Unknown channel option 'SO_TIMEOUT' for channel '[id: 0x7cb9183c]'
Modifications:
- Add OioDatagramChannelConfig and impl
- Correctly set SO_TIMEOUT in testsuite
Result:
Support SO_TIMEOUT for OioDatagramChannel and so faster execution of datagram related tests in the testsuite
Motivation:
Implementations of DuplexChannel delegate the shutdownOutput to the underlying transport, but do not take any action on the ChannelOutboundBuffer. In the event of a write failure due to the underlying transport failing and application may attempt to shutdown the output and allow the read side the transport to finish and detect the close. However this may result in an issue where writes are failed, this generates a writability change, we continue to write more data, and this may lead to another writability change, and this loop may continue. Shutting down the output should fail all pending writes and not allow any future writes to avoid this scenario.
Modifications:
- Implementations of DuplexChannel should null out the ChannelOutboundBuffer and fail all pending writes
Result:
More controlled sequencing for shutting down the output side of a channel.
Motivation:
We did not correctly handle connect() and disconnect() in EpollDatagramChannel / KQueueDatagramChannel and so the behavior was different compared to NioDatagramChannel.
Modifications:
- Correct implement connect and disconnect methods
- Share connect and related code
- Add tests
Result:
EpollDatagramChannel / KQueueDatagramChannel also supports correctly connect() and disconnect() methods.
Motivation:
We should not try to detect a free port in tests put just use 0 when bind so there is no race in which the system my bind something to the port we choosen before.
Modifications:
- Remove the usage of TestUtils.getFreePort() in the testsuite
- Remove hack to workaround bind errors which will not happen anymore now
Result:
Less flacky tests.
Motivation:
When run the current testsuite on docker (mac) it will fail a few tests with:
io.netty.channel.AbstractChannel$AnnotatedConnectException: connect(..) failed: Cannot assign requested address: /0:0:0:0:0:0:0:0%0:46607
Caused by: java.net.ConnectException: connect(..) failed: Cannot assign requested address
Modifications:
Specify host explicit as done in other tests to only use ipv6 when really supported.
Result:
Build pass on docker as well
Motivation:
Commit 3c4dfed08a introduced a regression in handling buffers that have no memoryAddress.
Modifications:
Fix regression and also add unit tests.
Result:
It's possible again to write buffers without memory address.
Motivation:
1. special handling of ByteBuf with multi nioBuffer rather than type of CompositeByteBuf (eg. DuplicatedByteBuf with CompositeByteBuf)
2. EpollDatagramUnicastTest and KQueueDatagramUnicastTest passed because CompositeByteBuf is converted to DuplicatedByteBuf before write to channel
3. uninitalized struct msghdr will raise error
Modifications:
1. isBufferCopyNeededForWrite(like isSingleDirectBuffer in NioDatgramChannel) checks wether a new direct buffer is needed
2. special handling of ByteBuf with multi nioBuffer in EpollDatagramChannel, AbstractEpollStreamChannel, KQueueDatagramChannel, AbstractKQueueStreamChannel and IovArray
3. initalize struct msghdr
Result:
handle of ByteBuf with multi nioBuffer in EpollDatagramChannel and KQueueDatagramChannel are ok
Motivation:
We only can call eventLoop() if we are registered on an EventLoop yet. As we just did this without checking we spammed the log with an error that was harmless.
Modifications:
Check if registered on eventLoop before try to deregister on close.
Result:
Fixes [#6770]
Motivation:
We currently don't have a native transport which supports kqueue https://www.freebsd.org/cgi/man.cgi?query=kqueue&sektion=2. This can be useful for BSD systems such as MacOS to take advantage of native features, and provide feature parity with the Linux native transport.
Modifications:
- Make a new transport-native-unix-common module with all the java classes and JNI code for generic unix items. This module will build a static library for each unix platform, and included in the dynamic libraries used for JNI (e.g. transport-native-epoll, and eventually kqueue).
- Make a new transport-native-unix-common-tests module where the tests for the transport-native-unix-common module will live. This is so each unix platform can inherit from these test and ensure they pass.
- Add a new transport-native-kqueue module which uses JNI to directly interact with kqueue
Result:
JNI support for kqueue.
Fixes https://github.com/netty/netty/issues/2448
Fixes https://github.com/netty/netty/issues/4231
Make the FileRegion comments about which transports are supported more accurate.
Also, eleminate any outstanding references to FileRegion.transfered as the method was renamed for spelling.
Modifications:
Class-level comment on FileRegion, can call renamed method.
Result:
More accurate documentation and less calls to deprecated methods.
Motivation:
Calling a static method is faster then dynamic
Modifications:
Add 'static' keyword for methods where it missed
Result:
A bit faster method calls
Motivation:
We should move the AutobahnTestsuite to an extra module. This allows easier to run only the testsuite or only the autobahntestsuite
Modifications:
Create a new module (testsuite-autobahn)
Result:
Better project structure.
Motivation:
autobahntestsuite-maven-plugin 0.1.4 was released and supports Java9.
Modifications:
Update plugin to be able to run tests on Java9
Result:
Autobahntestsuite can also be run on Java9.
Motivation:
We have our own ThreadLocalRandom implementation to support older JDKs . That said we should prefer the JDK provided when running on JDK >= 7
Modification:
Using ThreadLocalRandom implementation of the JDK when possible.
Result:
Make use of JDK implementations when possible.
Motivation:
We missed some stuff in 5728e0eb2c and so the build failed on java9
Modifications:
- Add extra cmdline args when needed
- skip the autobahntestsuite as jython not works with java9
- skip the osgi testsuite as the maven plugin not works with java9
Result:
Build finally passed on java9
Motivation:
When the EPOLLRDHUP event is received we assume that the read side of the FD is no longer functional and force the input state to be shutdown. However if the channel is still active we should rely upon EPOLLIN and read to indicate there is no more data before we update the shutdown state. If we do not do this we may not read all pending data in the FD if the RecvByteBufAllocator doesn't want to consume it all in a single read operation.
Modifications:
- AbstractEpollChannel#epollRdHupReady() shouldn't force shutdown the input if the channel is active
Result:
All data can be read even if the RecvByteBufAllocator doesn't read it all in the current read loop.
Fixes https://github.com/netty/netty/issues/6303
Motivation:
We need to pass special arguments to run with jdk9 as otherwise some tests will not be able to run.
Modifications:
Allow to define extra arguments when running with jdk9
Result:
Tests pass with jdk9
Motivation:
EpollRecvByteAllocatorHandle intends to override the meaning of "maybe more data to read" which is a concept also used in all existing implementations of RecvByteBufAllocator$Handle but the interface doesn't support overriding. Because the interfaces lack the ability to propagate this computation EpollRecvByteAllocatorHandle attempts to implement a heuristic on top of the delegate which may lead to reading when we shouldn't or not reading data.
Modifications:
- Create a new interface ExtendedRecvByteBufAllocator and ExtendedHandle which allows the "maybe more data to read" between interfaces
- Deprecate RecvByteBufAllocator and change all existing implementations to extend ExtendedRecvByteBufAllocator
- transport-native-epoll should require ExtendedRecvByteBufAllocator so the "maybe more data to read" can be propagated to the ExtendedHandle
Result:
Fixes https://github.com/netty/netty/issues/6303.
Motivation:
We used various mocking frameworks. We should only use one...
Modifications:
Make usage of mocking framework consistent by only using Mockito.
Result:
Less dependencies and more consistent mocking usage.
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.
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.
Motivation:
8ba5b5f740 removed some ciphers from the default list, and SocketSslEchoTest had one of these ciphers hard coded in the test. The test will fail if the cihper is not supported by default.
Modifications:
SocketSslEchoTest should ensure a cipher is used which will be supported by the peer
Result:
Test result no longer depends upon default cipher list.
Motivation:
the build doesnt seem to enforce this, so they piled up
Modifications:
removed unused import lines
Result:
less unused imports
Signed-off-by: radai-rosenblatt <radai.rosenblatt@gmail.com>
Motivation:
At the moment only DefaultFileRegion is supported when using the native epoll transport.
Modification:
- Add support for any FileRegion implementation
- Add test case
Result:
Also custom FileRegion implementation are supported when using the epoll transport.
Motivition:
NIO throws ClosedChannelException when a user tries to call shutdown*() on a closed Channel. We should do the same for the EPOLL transport
Modification:
Throw ClosedChannelException when a user tries to call shutdown*() on a closed channel.
Result:
Consistent behavior.
Motivation:
The NIO transport used an IllegalStateException if a user tried to issue another connect(...) while the connect was still in process. For this case the JDK specified a ConnectPendingException which we should use. The same issues exists in the EPOLL transport. Beside this the EPOLL transport also does not throw the right exceptions for ENETUNREACH and EISCONN errno codes.
Modifications:
- Replace IllegalStateException with ConnectPendingException in NIO and EPOLL transport
- throw correct exceptions for ENETUNREACH and EISCONN in EPOLL transport
- Add test case
Result:
More correct error handling for connect attempts when using NIO and EPOLL transport
Motivation:
We need to ensure we also call fireChannelActive() if the Channel is directly closed in a ChannelFutureListener that is belongs to the promise for the connect. Otherwise we will see missing active events.
Modifications:
Ensure we always call fireChannelActive() if the Channel was active.
Result:
No missing events.
Motivation:
We should throw a NotYetConnectedException when ENOTCONN errno is set. This is also consistent with NIO.
Modification:
Throw correct exception and add test case
Result:
More correct and consistent behavior.
Motivation:
For lack of a better way the SocketRstTest inspects the content of the exception message to check if a RST occurred. However on windows the exception message is different than on other Unix based platforms and the assertion statement fails.
Modifications:
- Hack another string check in the unit test
Result:
SocketRstTest passes on windows
Fixes https://github.com/netty/netty/issues/5335
Motivation:
At the moment the user is responsible to increase the writer index of the composite buffer when a new component is added. We should add some methods that handle this for the user as this is the most popular usage of the composite buffer.
Modifications:
Add new methods that autoamtically increase the writerIndex when buffers are added.
Result:
Easier usage of CompositeByteBuf.
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
Motivation:
We missed to correctly retrieve the localAddress() after we called Socket.connect(..) and so the user would always see an incorrect address when calling EpollSocketChannel.localAddress().
Modifications:
- Ensure we always retrieve the localAddress() after we called Socket.connect(...) as only after this we will be able to receive the correct address.
- Add unit test
Result:
Correct and consistent behaviour across different transports (NIO/OIO/EPOLL).
Motivation:
OIO/NIO use a volatile variable to track if a read is pending. EPOLL does not use a volatile an executes a Runnable on the event loop thread to set readPending to false. These mechansims should be consistent, and not using a volatile variable is preferable because the variable is written to frequently in the event loop thread.
OIO also does not set readPending to false before each fireChannelRead operation and may result in reading more data than the user desires.
Modifications:
- OIO/NIO should not use a volatile variable for readPending
- OIO should set readPending to false before each fireChannelRead
Result:
OIO/NIO/EPOLL are more consistent w.r.t. readPending and volatile variable operations are reduced
Fixes https://github.com/netty/netty/issues/5069
Motivation:
If SO_LINGER is set to 0 the EPOLL transport will send a FIN followed by a RST. This is not consistent with the behavior of the NIO transport. This variation in behavior can cause protocol violations in streaming protocols (e.g. HTTP) where a FIN may be interpreted as a valid end to a data stream, but RST may be treated as the data is corrupted and should be discarded.
https://github.com/netty/netty/issues/4170 Claims the behavior of NIO always issues a shutdown when close occurs. I could not find any evidence of this in Netty's NIO transport nor in the JDK's SocketChannel.close() implementation.
Modifications:
- AbstractEpollChannel should be consistent with the NIO transport and not force a shutdown on every close
- FileDescriptor to keep state in a consistent manner with the JDK and not allow a shutdown after a close
- Unit tests for NIO and EPOLL to ensure consistent behavior
Result:
EPOLL is capable of sending just a RST to terminate a connection.
Motivation:
netty-tcnative-1.1.33.Fork was released, we should upgrade. Also we should skip renegotiate tests if boringssl is used because boringssl does not support renegotiation.
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.
Motivation:
As we now can easily build static linked versions of tcnative it makes sense to run our netty build against all of them.
This helps to ensure our code works with libressl, openssl and boringssl.
Modifications:
Allow to specify -Dtcnative.artifactId= and -Dtcnative.version=
Result:
Easy to run netty build against different tcnative flavors.
Motivation:
Warnings in IDE, unclean code, negligible performance impact.
Modification:
Deletion of unused imports
Result:
No more warnings in IDE, cleaner code, negligible performance improvement.
Motivation:
Javadoc reports errors about invalid docs.
Modifications:
Fix some errors reported by javadoc.
Result:
A lot of javadoc errors are fixed by this patch.
Motivation:
RC4 is not supported by default in more recent java versions as RC4 is considered insecure. We should not use it in tests as these test will fail on more recent java version.
Modifications:
Use SSL_RSA_WITH_3DES_EDE_CBC_SHA for test.
Result:
Non failing test on more recent java versions.
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.
Motivation:
As stated in the SSLSession javadocs getPeer* methods need to throw a SSLPeerUnverifiedException if peers identity has not be verified.
Modifications:
- Correctly throw SSLPeerUnverifiedException
- Add test for it.
Result:
Correctly behave like descripted in javadocs.
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.
