1fef3872fb Update CertificateRequestCallback usage to match new tcnative
Motiviation:

Previously the way how CertificateRequestCallback was working had some issues which could cause memory leaks and segfaults. Due of this tcnative code was updated to change the signature of the method provided by the interface.

Modifications:

Update CertificateRequestCallback implementations to match new interface signature.

Result:

No more segfaults / memory leaks when using boringssl or openssl >= 1.1.0

d3cb95ef00 Make NIO and EPOLL transport connect errors more consistent with the JDK
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

3a6157e2aa Unit Test for SslHandler's handlerRemoved()
Motivation

SslHandler's handlerRemoved() is supposed to release the SSLEngine (which it does) but there is no Test for it to make sure it really happens and doesn't unexpectedly change in the future.

Modifications

Add a Unit Test that makes sure that SslHandler releases the SSLEngine when the Channel gets closed.

Result

Assurance that SslHandler will not leak (ReferenceCounted) SSLEngines.

a01519e4f8 [#5718] Result of ByteBufUtil.compare(ByteBuf a, ByteBuf b) is dependent on ByteOrder of supplied ByteBufs
Motivation:

Result of ByteBufUtil.compare(ByteBuf a, ByteBuf b) is dependent on ByteOrder of supplied ByteBufs which should not be the case (as stated in the javadocs).

Modifications:

Ensure we get a consistent behavior when calling ByteBufUtil.compare(ByteBuf a, ByteBuf b) and not depend on ByteOrder.

Result:

ByteBufUtil.compare(ByteBuf a, ByteBuf b) and so AbstractByteBuf.compare(...) works correctly as stated in the javadocs.

5b46cf25c1 Fulfill the write promise of empty HTTP/2 DATA frames sooner
Motivation:

DefaultHttp2ConnectionEncoder.FlowControlledData.write() does not
complete the write promise of empty HTTP/2 DATA frames until either a
non-DATA frame, a non-empty DATA frame or a DATA frame with endOfStream
set. This makes the write promise of the empty DATA frame is notified
much later than it could be.

Modifications:

- Notify the write promise of the empty DATA frames immediately is the
  queue contains empty DATA frames only

Result:

The write promise of an empty DATA frame is notified sooner.

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:
Fixes https://github.com/netty/netty/issues/5678

208893aac9 HTTP/2 Hpack Encoder Cleanup
Motivation:
The HTTP/2 HPACK Encoder class has some code which is only used for test purposes. This code can be removed to reduce complexity and member variable count.

Modifications:
- Remove test code and update unit tests
- Other minor cleanup

Result:
Test code is removed from operational code.

4accd300e5 Fix write watermarks comparison to use less than and greater than.
Motivation:

The API documentation in ChannelConfig states that a a channel is writable,
if the number of pending bytes is below the low watermark and a
channel is not writable, if the number of pending bytes exceeds the high
watermark.

Therefore, we should use < operators instead of <= as well as > instead of >=.

Using <= and >= is also problematic, if the low watermark is equal to the high watermark,
as then a channel could be both writable and unwritable with the same number of pending
bytes (depending on whether remove() or addMessage() is called first).

The use of <= and >= was introduced in PR https://github.com/netty/netty/pull/3036, but
I don't understand why, as there doesn't seem to have been any discussion around that.

Modifications:

Use < and > operators instead of <= and >=.

Result:

High and low watermarks are treated as stated in the API docs.

ecd6e5ce6d CorsHandler to respect http connection (keep-alive) header.
Motivation:

The CorsHandler currently closes the channel when it responds to a preflight (OPTIONS)
request or in the event of a short circuit due to failed validation.

Especially in an environment where there's a proxy in front of the service this causes
unnecessary connection churn.

Modifications:

CorsHandler now uses HttpUtil to determine if the connection should be closed
after responding

Result:

Channel will stay open when the CorsHandler responds unless the client specifies otherwise
or the protocol version is HTTP/1.0

5e148d5670 [#5639] Ensure fireChannelActive() is also called if Channel is closed in connect promise.
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.

2c1f17faa2 Throw correct NotYetConnectedException when ENOTCONN errno is set
Motivation:

We should throw a NotYetConnectedException when ENOTCONN errno is set. This is also consistent with NIO.

Modification:

Result:

More correct and consistent behavior.

43626ac6ea Use NIO methods when using Java7+ in the NIO transport
Motivation:

We use often javachannel().socket().* in NIO as these methods exists in java6. The problem is that these will throw often very general Exceptions (Like SocketException) while it is more expected to throw the Exceptions listed in the nio interfaces. When possible we should use the new methods available in java7+ which throw the correct exceptions.

Modifications:

Check for java version and depending on it using the socket or the javachannel.

Result:

Throw expected Exceptions.

8ce7e73e78 Prevent extra peformance hit by fillInStackTrace() when create a new annotated connect exception.
Motivation:

To make it easier to debug connect exceptions we create new exceptions which also contain the remote address. For this we basically created a new instance and call setStackTrace(...). When doing this we pay an extra penality because it calls fillInStackTrace() when calling the super constructor.

Modifications:

Create special sub-classes of Exceptions that override the fillInStackTrace() method and so eliminate the overhead.

Result:

Less overhead when "annotate" connect exceptions.

2d111e0980 Ensure SslHandler.close(...) will not throw exception if flush of pending messages fails
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

3451b3cbb3 Cookie name must be case sensitive
Motivation:

RFC 6265 does not state that cookie names must be case insensitive.

Modifications:

Fix io.netty.handler.codec.http.cookie.DefaultCookie#equals() method to
use case sensitive String#equals() and String#compareTo().

Result:

It is possible to parse several cookies with same names but with
different cases.

9bc3e56647 ReferenceCountedOpenSslEngineTest cleanup sequencing bug
Motivation:
ReferenceCountedOpenSslEngine depends upon the the SslContext to cleanup JNI resources. If we don't wait until the ReferenceCountedOpenSslEngine is done with cleanup before cleaning up the SslContext we may crash the JVM.

Modifications:
- Wait for the channels to close (and thus the ReferenceCountedOpenSslEngine to be cleaned up) before cleaning up the associated SslContext.

Result:
Cleanup sequencing is correct and no more JVM crash.

5fd239c29c Ensure we not log missleading errors if the promise was already failed due errors
Motivation:

In DefaultHttp2ConnectionEncoder we fail the promise in in the FlowControlledData.error(...) method but also add it the CoalescingBufferQueue. Which can lead to have the promise failed by error(...) before it can be failed in CoalescingBufferQueue.

This can lead to confusing and missleading errors in the log like:
    2016-08-12 09:47:43,716       nettyIoExecutorGroup-1-9 [WARN ] PromiseNotifier                - Failed to mark a promise as failure because it's done already: DefaultChannelPromise@374225e0(failure: javax.net.ssl.SSLException: SSLEngine closed already)
    javax.net.ssl.SSLException: SSLEngine closed already
        at io.netty.handler.ssl.SslHandler.wrap(...)(Unknown Source) ~[netty-all-4.1.5.Final-SNAPSHOT.jar:?]

Modifications:

Ensure we only fail the queue (which will also fail the promise).

Result:

No more missleading logs.

382f8eacaf Correctly fail all promises SSLENGINE_CLOSED once the engine is closed
Motivation:

We should fail all promises with the correct SSLENGINE_CLOSED exception one the engine is closed. We did not fail the current promise with this exception if the ByteBuf was not readable.

Modifications:

Correctly fail promises.

Result:

More correct handling of promises if the SSLEngine is closed.

d568cfc14a HTTP/2: Treat MAX_CONCURRENT_STREAMS exceeded as a stream error.
Motivation:

As per the HTTP/2 spec, exceeding the MAX_CONCURRENT_STREAMS should be treated as a stream error as opposed to a connection error.

"An endpoint that receives a HEADERS frame that causes its advertised concurrent stream limit to be exceeded MUST treat this as a stream error (Section 5.4.2) of type PROTOCOL_ERROR or REFUSED_STREAM." http://httpwg.org/specs/rfc7540.html#rfc.section.5.1.2

Modifications:

Make the error a stream error.

Result:

It's a stream error.

e7449b1ef3 [#5645] Allow to create ByteBuf from existing memory address.
Motivation:

Sometimes it is useful to be able to wrap an existing memory address (a.k.a pointer) and create a ByteBuf from it. This way its easier to interopt with other libraries.

Modifications:

Add a new Unpooled.wrappedBuffer(....) method that takes a memory address.

Result:

Be able to wrap an existing memory address into a ByteBuf.

00f74b92fa Fix the tcnative lib loading problem in OSGi
Motivation:

As the issue #5539 say, the OpenSsl.class will throw `java.lang.UnsatisfiedLinkError: org.apache.tomcat.jni.Library.version(I)I` when it is invoked. This path try to resolve the problem by modifying the native library loading logic of OpenSsl.class.

Modifications:

The OpenSsl.class loads the tcnative lib by `NativeLibraryLoader.loadFirstAvailable()`. The native library will be loaded in the bundle `netty-common`'s ClassLoader, which is diff with the native class's ClassLoader. That is the root cause of throws `UnsatisfiedLinkError` when the native method is invoked.
So, it should load the native library by the its bundle classloader firstly, then the embedded resources if failed.

Result:

First of all, the error threw by native method problem will be resolved.
Secondly, the native library should work as normal in non-OSGi env. But, this is hard. The loading logic of `Library.class` in `netty-tcnative` bundle is simple: try to load the library in PATH env. If not found, it falls back to the originally logic `NativeLibraryLoader.loadFirstAvailable()`.

8d043cc4dd Do not return Access-Control-Allow-Headers on Non-Preflight Cors requests
Motivation:

The CorsHandler currently returns the Access-Control-Allow-Headers
header as on a Non-Preflight CORS request (Simple request).
As per the CORS specification the Access-Control-Allow-Headers header
should only be returned on Preflight requests. (not on simple requests).

https://www.w3.org/TR/2014/REC-cors-20140116/#access-control-allow-headers-response-header

http://www.html5rocks.com/static/images/cors_server_flowchart.png

Modifications:

Modified CorsHandler.java to not add the Access-Control-Allow-Headers
header when responding to Non-preflight CORS request.

Result:

Access-Control-Allow-Headers header will not be returned on a Simple
request (Non-preflight CORS request).

fa6b0e262e Support Unicode filenames and spaces in directory listing
Motivation:

The HTTP Static File Server seems to ignore filenames that doesn't contains only latin characters, but these days people wish to serve files in other languages, or even include some emojis in the filename. Although these files are not displayed on the directory listing, they are accessible by HTTP requests. This fix will make such files more visible.

Modifications:

I've changed the ALLOWED_FILE_NAME pattern to disallow only files that starts with underline, minus or a dot (such as .htaccess), and hide other "unsafe" filenames that may be used to trigger some security issues. Other filenames, including the space character are allowed.

I've also added charset encoding to the directory listing, because the browser default MAY be configured for ISO-8859-1 instead of UTF-8.

Result:

Directory listing will work for files that contains the space character, as well as other Unicode characters.

15222c084d Never expose user.dir to the web on directory listing
Motivation:

When Netty HTTP Static File Server does directory listing, it does expose the user.dir environment variable to the user. Although it doesn't a security issue, it is a bad practice to show it, and the user does expect to see the server virtual root instead, which is the absolute path as mentioned in the RFC.

Modifications:

the sendListing method receives a third argument, which is the requested URI, and this is what should be displayed on the page instead of the filesystem path.

Result:

The directory listing pages will show the virtual path as described in the URI and not the real filesystem path.

b963595988 Fix handling of non direct backed PemEncoded.
Motivation:

The private key and certificate that are passed into #serKeyMaterial() could be PemEncoded in which case the #toPEM() methods return the identity of the value.

That in turn will fail in the #toBIO() step because the underlying ByteBuf is not necessarily direct.

Modifications:

- Use toBIO(...) which also works with non direct PemEncoded values
- Add unit test.

Result:

Correct handling of PemEncoded.

3a4d30df4e Make SocksServer example compatible with curl --socks5-hostname
Motivation:

Socks5 proxy supports resolve domain at the server side. When testing
with curl, the SocksServer in example package only works for proxy
request with IP, not with domain name (`--socks5` vs
`--socks5-hostname`). As curl is widely used, it should work with
the example provided.

Modifications:

Passing address and port to the Socks5CommandResponse, so that it
works for curl.

Result:

`curl --socks5-hostname` works as expected.

f73c4f24ee HTTP/2 HPACK Bounds Check Fix
Motivation:
21e8d84b79 changed the way bounds checking was done, but however a bounds check in the case of READ_LITERAL_HEADER_NAME_LENGTH_PREFIX was using an old value. This would delay when the bounds check would actually be done and potentially allow more allocation than necessary.

Modifications:
- Use the new length (index) in the bounds check instead of an old length (nameLength) which had not yet been assigned to the new value.

Result:
More correct bounds checking.

21e8d84b79 HTTP/2 Simplify Headers Decode Bounds Checking
Motivation:
The HPACK decoder keeps state so that the decode method can be called multiple times with successive header fragments. This decoder also requires that a method is called to signify the decoding is complete. At this point status is returned to indicate if the max header size has been violated. Netty always accumulates the header fragments into a single buffer before attempting to HPACK decode process and so keeping state and delaying notification that bounds have been exceeded is not necessary.

Modifications:
- HPACK Decoder#decode(..) now must be called with a complete header block
- HPACK will terminate immediately if the maximum header length, or maximum number of headers is exceeded
- Reduce member variables in the HPACK Decoder class because they can now live in the decode(..) method

Result:
HPACK bounds checking is done earlier and less class state is needed.

4d74bf3984 HTTP/2 MaxStreams cleanup
Motivation:
765e944d4d imposed a limit on the maximum number of stream in all states. However the default limit did not allow room for streams in addition to SETTINGS_MAX_CONCURRENT_STREAMS. This can mean streams in states outside the states which SETTINGS_MAX_CONCURRENT_STREAMS applies to may not be reliably created.

Modifications:
- The default limit should be larger than SETTINGS_MAX_CONCURRENT_STREAMS

More lenient limit is applied to maxStreams by default.

765e944d4d HTTP/2 limit streams in all states
Motivation:
SETTINGS_MAX_CONCURRENT_STREAMS does not apply to idle streams and thus we do not apply any explicit limitations on how many idle streams can be created. This may allow a peer to consume an undesirable amount of resources.

Modifications:
- Each Endpoint should enforce a limit for streams in a any state. By default this limit will be the same as SETTINGS_MAX_CONCURRENT_STREAMS but can be overridden if necessary.

Result:
There is now a limit to how many IDLE streams can be created.

ef159db320 Delete temporary .so file after loading
Motivation:

Our current strategy in NativeLibraryLoader is to mark the temporary .so file to be deleted on JVM exit. This has the drawback to not delete the file in the case the JVM dies or is killed.

Modification:

Just directly try to delete the file one we loaded the native library and if this fails mark the file to be removed once the JVM exits.

Result:

Less likely to have temporary files still on the system in case of JVM kills.

1abdbe6f67 AbstractByteBuf forEach minimize byte code
Motivation:
The default limit for the maximum amount of bytes that a method will be inlined is 35 bytes. AbstractByteBuf#forEach and AbstractByteBuf#forEachDesc comprise of method calls which are more than this maximum default threshold and may prevent or delay inlining for occuring. The byte code for these methods can be reduced to allow for easier inlining. Here are the current byte code sizes:

AbstractByteBuf::forEachByte (24 bytes)
AbstractByteBuf::forEachByte(int,int,..) (14 bytes)
AbstractByteBuf::forEachByteAsc0 (71 bytes)
AbstractByteBuf::forEachByteDesc (24 bytes)
AbstractByteBuf::forEachByteDesc(int,int,.) (24 bytes)
AbstractByteBuf::forEachByteDesc0 (69 bytes)

Modifications:
- Reduce the code for each method in the AbstractByteBuf#forEach and AbstractByteBuf#forEachDesc call stack

Result:
AbstractByteBuf::forEachByte (25 bytes)
AbstractByteBuf::forEachByte(int,int,..) (25 bytes)
AbstractByteBuf::forEachByteAsc0 (29 bytes)
AbstractByteBuf::forEachByteDesc (25 bytes)
