Added support for the SameSite attribute in Cookies (#10050)
Motivation:

Netty currently does not support the SameSite attribute for response cookies (see issue #8161 for discussion).

Modifications:

The attribute has been added to the DefaultCookie class as a quick fix since adding new methods to the Cookie interface would be backwards-incompatible.
ServerCookieEncoder and ClientCookieDecoder have been updated accordingly to process this value. No validation for allowed values (Lax, None, Strict) has been implemented.

Result:

Response cookies with the SameSite attribute set can be read or written by Netty.

Fix WebSocketClientHandshaker not generating correct handshake request when path is empty (#10095)
Motivation:

WebSocketClientHandshaker#upgradeUrl doesn't comperly compute relative url when path is empty and produces url such as `?access_token=foo` instead of `/?access_token=foo`.

Modifications:

* fix WebSocketClientHandshaker#upgradeUrl
* add tests for urls without path, with and without query

Result:

WebSocketClientHandshaker properly connects to url without path.

http multipart decode with chinese chars should work (#10089)
Motivation:

I am receiving a mutlipart/form_data upload from postman. The filename contains Chinese, and so some invalid chars. We should ensure all of these are removed before trying to decode.

Modification:

Ensure all invalid characters are removed

Result:

Fixes #10087

Preserve order when using alternate event loops (#10069)
Motivation:

When the HttpContentCompressor is put on an alternate EventExecutor, the order of events should be
preserved so that the compressed content is correctly created.

Modifications:
- checking that the executor in the ChannelHandlerContext is the same executor as the current executor when evaluating if the handler should be skipped.
- Add unit test

Result:

Fixes https://github.com/netty/netty/issues/10067

More strict parsing of initial line / http headers (#10058)
Motivation:

Our parsing of the initial line / http headers did treat some characters as separators which should better trigger an exception during parsing.

Modifications:

- Tighten up parsing of the inital line by follow recommentation of RFC7230
- Restrict separators to OWS for http headers
- Add unit test

Result:

Stricter parsing of HTTP1

6290346246 Remove "Content-Length" when decoding HTTP/1.1 message with both "Tra… (#10003)
Motivation

As part of a recent commit for issue
https://github.com/netty/netty/issues/9861 the HttpObjectDecoder was
changed to throw an IllegalArgumentException (and produce a failed
decoder result) when decoding a message with both "Transfer-Encoding:
chunked" and "Content-Length".

While it seems correct for Netty to try to sanitize these types of
messages, the spec explicitly mentions that the Content-Length header
should be *removed* in this scenario.

Both Nginx 1.15.9 and Tomcat 9.0.31 also opt to remove the header:
b693d7c198/java/org/apache/coyote/http11/Http11Processor.java (L747-L755)
0ad4393e30/src/http/ngx_http_request.c (L1946-L1953)

Modifications

* Change the default behavior from throwing an IllegalArgumentException
to removing the "Content-Length" header
* Extract the behavior to a new protected method,
handleChunkedEncodingWithContentLength(), that can be overridden to
change this behavior (or capture metrics)

Result

Messages of this nature will now be successfully decoded and have their
"Content-Length" header removed, rather than creating invalid messages
(decoder result failures). Users will be allowed to override and
configure this behavior.

Added tests for Transfer-Encoding header with whitespace (#9997)
Motivation:

Need tests to ensure that CVE-2020-7238 is fixed.

Modifications:

Added two test cases into HttpRequestDecoderTest which check that
no whitespace is allowed before the Transfer-Encoding header.

Result:

Use compile time constants instead of status field in WebSocketServer/ClientProtocolConfig (#9976)
Motivation:

Avoid allocation of default static `WebSocketServerProtocolConfig` and `WebSocketClientProtocolConfig` configs. Prefer compile time constants instead.

Modification:

Static field with config object replaced with constructor with default fields.

Result:

No more default config allocation and static field for it. Compile time variables used instead.

fb3ced28cf #9944 Merge WebSocketCloseFrameHandler into WebSocketProtocolHandler … (#9967)
…in order to minimize pipeline

Motivation:

Handling of `WebSocketCloseFrame` is part of websocket protocol, so it's logical to put it within the `WebSocketProtocolHandler`. Also, removal of `WebSocketCloseFrameHandler` will decrease the channel pipeline.

Modification:

- `WebSocketCloseFrameHandler` code merged into `WebSocketProtocolHandler`. `WebSocketCloseFrameHandler` not added to the pipeline anymore
- Added additional constructor to `WebSocketProtocolHandler`
- `WebSocketProtocolHandler` now implements `ChannelOutboundHandler` and implements basic methods from it

Result:

`WebSocketCloseFrameHandler` is no longer used.

Remove usage of forbiddenHttpRequestResponder (#9941)
Motivation:

At the moment we add a handler which will respond with 403 forbidden if a websocket handshake is in progress (and after). This makes not much sense as it is unexpected to have a remote peer to send another http request when the handshake was started. In this case it is much better to let the websocket decoder bail out.

Modifications:

Remove usage of forbiddenHttpRequestResponder

Result:

Fixes https://github.com/netty/netty/issues/9913

c9d8152e88 Fix remove 'WebSocketServerExtensionHandler' from pipeline after upgrade (#9940)
Motivation:

We should remove WebSocketServerExtensionHandler from pipeline after successful WebSocket upgrade even if the client has not selected any extensions.

Modification:

Remove handler once upgrade is complete and no extensions are used.

Result:

Fixes #9939.

687308b4de Separate out query string encoding for non-encoded strings. (#9887)
Motivation:

Currently, characters are appended to the encoded string char-by-char even when no encoding is needed. We can instead separate out codepath that appends the entire string in one go for better `StringBuilder` allocation performance.

Modification:

Only go into char-by-char loop when finding a character that requires encoding.

Result:

The results aren't so clear with noise on my hot laptop - the biggest impact is on long strings, both to reduce resizes of the buffer and also to reduce complexity of the loop. I don't think there's a significant downside though for the cases that hit the slow path.

f995426a59 Avoid possible comparison contract violation (#9883)
Motivation:

The current implementation causes IllegalArgumetExceptions to be thrown on Java 11.

The current implementation would violate comparison contract for two cookies C1 and C2 with same path length, since C1 < C2 and C2 < C1. Returning 0 (equality) does not since C1 == C2 and C2 == C1. See #9881

Modification:

Return equality instead of less than on same path length.

Result:

Fixes #9881.

95b8db0633 Use array to buffer decoded query instead of ByteBuffer. (#9886)
Motivation:

In Java, it is almost always at least slower to use `ByteBuffer` than `byte[]` without pooling or I/O. `QueryStringDecoder` can use `byte[]` with arguably simpler code.

Modification:

Replace `ByteBuffer` / `CharsetDecoder` with `byte[]` and `new String`

Result:

I notice #6781 switched from an array to `ByteBuffer` but I can't find any motivation for that in the PR. Unit tests pass fine with an array and we get a reasonable speed bump.

Verify we do not receive multiple content-length headers or a content-length and transfer-encoding: chunked header when using HTTP/1.1 (#9865)
Motivation:

RFC7230 states that we should not accept multiple content-length headers and also should not accept a content-length header in combination with transfer-encoding: chunked

- Check for multiple content-length headers and if found mark message as invalid
- Check if we found a content-length header and also a transfer-encoding: chunked and if so mark the message as invalid
- Add unit test

Note:

This change is not as perscriptive as the ideas brought up in the linked issue.  Changing the Set implementation or the equals/compareTo definition is likely a breaking change, so they are practical.

19a4633859 Bugfix #9673: Origin header is always sent from WebSocket client (#9692)
### Motivation:

Those who need 'Origin' or 'Sec-WebSocket-Origin' headers should provide them explicitly, like it is stated in WebSocket specs.

E.g. through custom headers:

    HttpHeaders customHeaders = new DefaultHttpHeaders()
        .add(HttpHeaderNames.ORIGIN, "http://localhost:8080");
    new WebSocketClientProtocolHandler(
        new URI("ws://localhost:1234/test"), WebSocketVersion.V13, subprotocol, 
        allowExtensions, customHeaders, maxFramePayloadLength, handshakeTimeoutMillis)


### Modification:

* Remove enforced origin headers.
* Update tests

8d99aa1235 Simplify WebSocket handlers constructor arguments hell #9698 (#9699)
### Motivation:

Introduction of `WebSocketDecoderConfig` made our server-side code more elegant and simpler for support.

However there is still some problem with maintenance and new features development for WebSocket codecs (`WebSocketServerProtocolHandler`, `WebSocketServerProtocolHandler`).

Particularly, it makes me ~~crying with blood~~ extremely sad to add new parameter and yet another one constructor into these handlers, when I want to contribute new feature.

### Modification:

I've extracted all parameters for client and server WebSocket handlers into config/builder structures, like it was made for decoders in PR #9116.

### Result:

* Fixes #9698: Simplify WebSocket handlers constructor arguments hell
* Unblock further development in this module (configurable close frame handling on server-side; automatic close-frame sending, when missed; memory leaks on protocol violations; etc...)

Bonuses:

* All defaults are gathered in one place and could be easily found/reused.
* New API greatly simplifies usage, but does NOT allow inheritance or modification.
* New API would simplify long-term maintenance of WebSockets module.

### Example

    WebSocketClientProtocolConfig config = WebSocketClientProtocolConfig.newBuilder()
        .webSocketUri("wss://localhost:8443/fx-spot")
        .subprotocol("trading")
        .handshakeTimeoutMillis(15000L)
        .build();
    ctx.pipeline().addLast(new WebSocketClientProtocolHandler(config));

e0b15ed952 [DOC] Add CWE-113 warning to DefaultHttpHeaders constructor (#9646)
### Motivation:

I've now found two libraries that use Netty to be vulnerable to [CWE-113: Improper Neutralization of CRLF Sequences in HTTP Headers ('HTTP Response Splitting')](https://cwe.mitre.org/data/definitions/113.html) due to using `new DefaultHttpHeaders(false)`.

Some part of me hopes that this warning will help dissuade library authors from disabling this important security check.

### Modification:

Add documentation to `DefaultHttpHeaders(boolean)` to warn about the implications of `false`.

### Result:

This improves the documentation on `DefaultHttpHeaders`.
