a89cde9475 Support cancellation in the Http2StreamChannelBootstrap (#9519)
Motivation:

Right now you can cancel the Future returned by
`Http2StreamChannelBootstrap.open()` and that will race with the
registration of the stream channel with the event loop, potentially
culminating in an `IllegalStateException` and potential resource leak.

Modification:

Ensure that the returned promise is uncancellable.

Result:

Should no longer see `IllegalStateException`s.

Reduce GC produced by AbstractByteBuf.indexOf(..) implementation (#9502)
Motivation:

AbstractByteBuf.indexOf(...) currently delegates to ByteBufUtils.indexOf(...) which will create a new ByteBufProcessor on each call. This is done to reduce overhead of bounds-checks. Unfortunally while this reduces bounds checks it produces a lot of GC. We can just implement our own version in AbstractByteBuf which makes use of _getByte(...) and so does no bound checks as well but also not need to create any garbage.

Modifications:

Write optimized implementation of indexOf(...) for AbstractByteBuf

Result:

Fixes https://github.com/netty/netty/issues/9499.

14e856ac72 Correctly handle client side http2 upgrades when Http2FrameCodec …(9495) (#9501)
Motivation:

In the release (4.1.37) we introduced Http2MultiplexHandler as a
replacement of Http2MultiplexCodec. This did split the frame parsing from
the multiplexing to allow a more flexible way to handle frames and to make
the code cleaner. Unfortunally we did miss to special handle this in
Http2ClientUpgradeCodec and so did not correctly add Http2MultiplexHandler
to the pipeline before calling Http2FrameCodec.onHttpClientUpgrade(...).
This did lead to the situation that we did not correctly receive the event
on the Http2MultiplexHandler and so did not correctly created the
Http2StreamChannel for the upgrade stream. Because of this we ended up
with an NPE if a frame was dispatched to the upgrade stream later on.

Modifications:

- Correctly add Http2MultiplexHandler to the pipeline before calling Http2FrameCodec.onHttpClientUpgrade(...)

Result:

Fixes #9495.

specifications. We should point them to the latest RFC 7540 or 7541.

Modifications:

85fcf4e581 Use AppendableCharSequence.charAtUnsafe(int) in HttpObjectDecoder (#9492)
Motivation:

`HttpObjectDecoder` pre-checks that it doesn't request characters
outside of the `AppendableCharSequence`'s length. `0` is always allowed
because the minimal length of `AppendableCharSequence` is `1`. We can
legally skip index check by using
`AppendableCharSequence.charAtUnsafe(int)` in all existing cases in
`HttpObjectDecoder`.

Modifications:

- Use `AppendableCharSequence.charAtUnsafe(int)` instead of
`AppendableCharSequence.charAt(int)` in `HttpObjectDecoder`.

Result:

No unnecessary index checks in `HttpObjectDecoder`.

a22d4ba859 Simplify EventLoop abstractions for timed scheduled tasks (#9470)
Motivation

The epoll transport was updated in #7834 to decouple setting of the
timerFd from the event loop, so that scheduling delayed tasks does not
require waking up epoll_wait. To achieve this, new overridable hooks
were added in the AbstractScheduledEventExecutor and
SingleThreadEventExecutor superclasses.

However, the minimumDelayScheduledTaskRemoved hook has no current
purpose and I can't envisage a _practical_ need for it. Removing
it would reduce complexity and avoid supporting this specific
API indefinitely. We can add something similar later if needed
but the opposite is not true.

There also isn't a _nice_ way to use the abstractions for
wakeup-avoidance optimizations in other EventLoops that don't have a
decoupled timer.

This PR replaces executeScheduledRunnable and
wakesUpForScheduledRunnable
with two new methods before/afterFutureTaskScheduled that have slightly
different semantics:
 - They only apply to additions; given the current internals there's no
practical use for removals
 - They allow per-submission wakeup decisions via a boolean return val,
which makes them easier to exploit from other existing EL impls (e.g.
NIO/KQueue)
 - They are subjectively "cleaner", taking just the deadline parameter
and not exposing Runnables
 - For current EL/queue impls, only the "after" hook is really needed,
but specialized blocking queue impls can conditionally wake on task
submission (I have one lined up)

Also included are further optimization/simplification/fixes to the
timerFd manipulation logic.

Modifications

- Remove AbstractScheduledEventExecutor#minimumDelayScheduledTaskRemoved()
and supporting methods
- Uplift NonWakeupRunnable and corresponding default wakesUpForTask()
impl from SingleThreadEventLoop to SingleThreadEventExecutor
- Change executeScheduledRunnable() to be package-private, and have a
final impl in SingleThreadEventExecutor which triggers new overridable
hooks before/afterFutureTaskScheduled()
- Remove unnecessary use of bookend tasks while draining the task queue
- Use new hooks to add simpler wake-up avoidance optimization to
NioEventLoop (primarily to demonstrate utility/simplicity)
- Reinstate removed EpollTest class

In EpollEventLoop:
 - Refactor to use only the new afterFutureTaskScheduled() hook for
updating timerFd
 - Fix setTimerFd race condition using a monitor
 - Set nextDeadlineNanos to a negative value while the EL is awake and
use this to block timer changes from outside the EL. Restore the
known-set value prior to sleeping, updating timerFd first if necessary
 - Don't read from timerFd when processing expiry event

Result

- Cleaner API for integrating with different EL/queue timing impls
- Fixed race condition to avoid missing scheduled wakeups
- Eliminate unnecessary timerFd updates while EL is awake, and
unnecessary expired timerFd reads
- Avoid unnecessary scheduled-task wakeups when using NIO transport

I did not yet further explore the suggestion of using
TFD_TIMER_ABSTIME for the timerFd.

873988676a Epoll: Avoid redundant EPOLL_CTL_MOD calls (#9397)
Motivation

Currently an epoll_ctl syscall is made every time there is a change to
the event interest flags (EPOLLIN, EPOLLOUT, etc) of a channel. These
are only done in the event loop so can be aggregated into 0 or 1 such
calls per channel prior to the next call to epoll_wait.

Modifications

I think further streamlining/simplification is possible but for now I've
tried to minimize structural changes and added the aggregation beneath
the existing flag manipulation logic.

A new AbstractChannel#activeFlags field records the flags last set on
the epoll fd for that channel. Calls to setFlag/clearFlag update the
flags field as before but instead of calling epoll_ctl immediately, just
set or clear a bit for the channel in a new bitset in the associated
EpollEventLoop to reflect whether there's any change to the last set
value.

Prior to calling epoll_wait the event loop makes the appropriate
epoll_ctl(EPOLL_CTL_MOD) call once for each channel who's bit is set.

Result

Fewer syscalls, particularly in some auto-read=false cases. Simplified
error handling from centralization of these calls.

Detect truncated responses caused by EDNS0 and MTU miss-match (#9468)
Motivation:

It is possible that the user uses a too big EDNS0 setting for the MTU and so we may receive a truncated datagram packet. In this case we should try to detect this and retry via TCP if possible

Modifications:

- Fix detecting of incomplete records
- Mark response as truncated if we did not consume the whole packet
- Add unit test

Replace synchronized usage with ConcurrentHashMap in *Bootstrap classes (#9458)
Motivation:

In AbstractBoostrap, options and attrs are LinkedHashMap that are synchronized on for every read, copy/clone, write operation.
When a lot of connections are triggered concurrently on the same bootstrap instance, the synchronized blocks lead to contention, Netty IO threads get blocked, and performance may be severely degraded.

Modifications:

Use ConcurrentHashMap

Result:

Less contention. Fixes https://github.com/netty/netty/issues/9426

4db38b4e0c Don't zero non-readable buffer regions when capacity is decreased (#9427)
Motivation

#1802 fixed ByteBuf implementations to ensure that the whole buffer
region is preserved when capacity is increased, not just the readable
part. The behaviour is still different however when the capacity is
_decreased_ - data outside the currently-readable region is zeroed.

Modifications

Update ByteBuf capacity(int) implementations to also copy the whole
buffer region when the new capacity is less than the current capacity.

Result

Consistent behaviour of ByteBuf#capacity(int) regardless of whether the
new capacity is greater than or less than the current capacity.

1fa7a5e697 EPOLL - decouple schedule tasks from epoll_wait life cycle (#7834)
Motivation:
EPOLL supports decoupling the timed wakeup mechanism from the selector call. The EPOLL transport takes advantage of this in order to offer more fine grained timer resolution. However we are current calling timerfd_settime on each call to epoll_wait and this is expensive. We don't have to re-arm the timer on every call to epoll_wait and instead only have to arm the timer when a task is scheduled with an earlier expiration than any other existing scheduled task.

Modifications:
- Before scheduled tasks are added to the task queue, we determine if the new
  duration is the soonest to expire, and if so update with timerfd_settime. We
also drain all the tasks at the end of the event loop to make sure we service
any expired tasks and get an accurate next time delay.
- EpollEventLoop maintains a volatile variable which represents the next deadline to expire. This variable is modified inside the event loop thread (before calling epoll_wait) and out side the event loop thread (immediately to ensure proper wakeup time).
- Execute the task queue before the schedule task priority queue. This means we
  may delay the processing of scheduled tasks but it ensures we transfer all
pending tasks from the task queue to the scheduled priority queue to run the
soonest to expire scheduled task first.
- Deprecate IORatio on EpollEventLoop, and drain the executor and scheduled queue on each event loop wakeup. Coupling the amount of time we are allowed to drain the executor queue to a proportion of time we process inbound IO may lead to unbounded queue sizes and unpredictable latency.

Result:
Fixes https://github.com/netty/netty/issues/7829
- In most cases this results in less calls to timerfd_settime
- Less event loop wakeups just to check for scheduled tasks executed outside the event loop
- More predictable executor queue and scheduled task queue draining
- More accurate and responsive scheduled task execution

HTTP2: Guard against empty DATA frames (without end_of_stream flag) set (#9461)
Motivation:

It is possible for a remote peer to flood the server / client with empty DATA frames (without end_of_stream flag) set and so cause high CPU usage without the possibility to ever hit a limit. We need to guard against this.

See CVE-2019-9518

Modifications:

- Add a new config option to AbstractHttp2ConnectionBuilder and sub-classes which allows to set the max number of consecutive empty DATA frames (without end_of_stream flag). After this limit is hit we will close the connection. A limit of 10 is used by default.
- Add unit tests

HTTP2: Add protection against remote control frames that are triggered by a remote peer (#9460)
Motivation:

Due how http2 spec is defined it is possible by a remote peer to flood us with frames that will trigger control frames as response, the problem here is that the remote peer can also just stop reading these (while still produce more of these) and so may drive us to the pointer where we either run out of memory or burn all CPU. To protect against this we need to implement some kind of limit that will tear down connections that cause the above mentioned situation.

See CVE-2019-9512 / CVE-2019-9514 / CVE-2019-9515

Modifications:

- Add Http2ControlFrameLimitEncoder which limits the number of queued control frames that were caused because of the remote peer.
- Allow to insert ths Http2ControlFrameLimitEncoder by setting AbstractHttp2ConnectionBuilder.encoderEnforceMaxQueuedControlFrames(...) to a number higher then 0. The default is 10000 which provides some protection by default but will hopefully not cause too many false-positives.
- Add unit tests

Result:

Protect against DDOS due control frames. Fixes CVE-2019-9512 / CVE-2019-9514 / CVE-2019-9515 .

695aa0959d Use alloc().heapBuffer(...) to allocate new heap buffer.
Motivation

Underlying array allocations in UnpooledHeapByteBuf are intended be done
via the protected allocateArray(int) method, so that they can be tracked
and/or overridden by subclasses, for example
UnpooledByteBufAllocator$InstrumentedUnpooledHeapByteBuf or #8015. But
it looks like an explicit allocation was missed in the copy(int,int)
method.

Modification

Just use alloc().heapBuffer(...) for the allocation

Result

No possibility of "missing" array allocations when ByteBuf#copy is used.

Delay Http2ConnectionPrefaceAndSettingsFrameWrittenEvent by one EventLoop tick when using the Http2FrameCodec (#9442)
Motivation:

We should delay the firing of the Http2ConnectionPrefaceAndSettingsFrameWrittenEvent by one EventLoop tick when using the Http2FrameCodec to ensure all handlers are added to the pipeline before the event is passed through it.

Always wrap X509ExtendedTrustManager when using OpenSSL and JDK < 11 (#9443)
Motivation:

When using OpenSSL and JDK < 11 is used we need to wrap the user provided X509ExtendedTrustManager to be able to support TLS1.3. We had a check in place that first tried to see if wrapping is needed at all which could lead to missleading calls of the user provided trustmanager. We should remove these calls and just always wrap if needed.

Modifications:

Always wrap if OpenSSL + JDK < 11 and TLS1.3 is supported

Result:

Less missleading calls to user provided trustmanager

Motivation:

Users' runtime systems may have incompatible dynamic libraries to the ones our
tcnative wrappers link to. Unfortunately, we cannot determine and catch these
scenarios (in which the JVM crashes) but we can make a more educated guess on
what library to load and try to find one that works better before crashing.

Modifications:

1) Build dynamically linked openSSL builds for more OSs (netty-tcnative)
2) Load native linux libraries with matching classifier (first)

Result:

More developers / users can use the dynamically-linked native libraries.

fedcc40196 Fix ByteBufUtil#writeUtf8 subsequence split surrogate edge-case bug (#9437)
Motivation:

#9224 introduced overrides of ByteBufUtil#writeUtf8(...) and related
methods to operate on a sub-CharSequence directly to save having to
allocate substrings, but it missed an edge case where the subsequence
does not extend to the end of the CharSequence and the last char in the
sequence is a high surrogate.

Due to the catch-IndexOutOfBoundsException optimization that avoids an
additional bounds check, it would be possible to read past the specified
end char index and successfully decode a surrogate pair which would
otherwise result in a '?' byte being written.

Modifications:

- Check for end-of-subsequence before reading next char after a high
surrogate is encountered in the
writeUtf8(AbstractByteBuf,int,CharSequence,int,int) and
utf8BytesNonAscii methods
- Add unit test for this edge case

Result:

Bug is fixed.

This removes the bounds-check-avoidance optimization but it does not
appear to have a measurable impact on benchmark results, including when
the char sequence contains many surrogate pairs (which should be rare in
any case).

cbc8fc4428 Fix HttpUtil.getCharset to not throw illegal charset exception (#9439)
Motivation:

If the HttpUtil.getCharset method is called with an illegal charset like
"charset=!illegal!" it throws an IllegalCharsetNameException. But the javadoc
states, that defaultCharset is returned if incorrect header value. Since the
client sending the request sets the header value this should not crash.

Modification:

HttpUtil.getCharset catches the IllegalCharsetNameException and returns the
defualt value.

Result:

HttpUtil.getCharset does not throw IllegalCharsetNameException any more.

configure picks this up and builds the native library in
native-build/target/lib64 where maven is not looking.

Modifications:

Explicitly specify --libdir=${project.build.directory}/native-build/target/lib
during configuration.

Result:

Maven uses the correct lib directory.

17f10d6a92 Update os-maven-plugin version to match netty-tcnative (#9409)
Motivation:

Since both projects (to some extend) rely on classifier parsing via the
os-maven-plugin, they should ideally use the same version in case the parsing
changed.

Modifications:

Upgrade os-maven-plugin from 1.6.0 to 1.6.2

Result:

Same os-maven-plugin with same parsing logic.

7c5a3c5898 Allow to turn off Utf8FrameValidator creation for websocket with Bina… (#9417)
…ryWebSocketFrames

Motivation:

`Utf8FrameValidator` is always created and added to the pipeline in `WebSocketServerProtocolHandler.handlerAdded` method. However, for websocket connection with only `BinaryWebSocketFrame`'s UTF8 validator is unnecessary overhead. Adding of `Utf8FrameValidator` could be easily avoided by extending of `WebSocketDecoderConfig` with additional property.

Specification requires UTF-8 validation only for `TextWebSocketFrame`.

Modification:

Added `boolean WebSocketDecoderConfig.withUTF8Validator` that allows to avoid adding of `Utf8FrameValidator` during pipeline initialization.

Result:

Less overhead when using only `BinaryWebSocketFrame`within web socket.

005fd55b88 #7285 Improved "Discarded inbound message" warning for embedded channel (#9414)
Motivation:

Look like `EmbeddedChannelPipeline` should also override `onUnhandledInboundMessage(ChannelHandlerContext ctx, Object msg)` in order to do not print "Discarded message pipeline" because in case of `EmbeddedChannelPipeline` discarding actually not happens.

This fixes next warning in the latest netty version with websocket and `WebSocketServerCompressionHandler`:

```
13:36:36.231 DEBUG- Decoding WebSocket Frame opCode=2
13:36:36.231 DEBUG- Decoding WebSocket Frame length=5
13:36:36.231 DEBUG- Discarded message pipeline : [JdkZlibDecoder#0, DefaultChannelPipeline$TailContext#0]. Channel : [id: 0xembedded, L:embedded - R:embedded].
```

Modification:

Override correct method

Result:
Follow up fix after https://github.com/netty/netty/pull/9286

1194577bd0 Decrease the level of logging in WebSocketFrameEncoder/Decoder (#9415)
Motivation:

Our QA servers are spammed with this messages:

13:57:51.560 DEBUG- Decoding WebSocket Frame opCode=1
13:57:51.560 DEBUG- Decoding WebSocket Frame length=4
I think this is too much info for debug level. It is better to move it to trace level.

Modification:

logger.debug changed to logger.trace for WebSocketFrameEncoder/Decoder

Result:

Less messages in Debug mode.
