SslHandler LocalChannel read/unwrap reentry fix (#11156)
Motivation:
SslHandler invokes channel.read() during the handshake process. For some
channel implementations (e.g. LocalChannel) this may result in re-entry
conditions into unwrap. Unwrap currently defers updating the input
buffer indexes until the unwrap method returns to avoid intermediate
updates if not necessary, but this may result in unwrapping the same
contents multiple times which leads to handshake failures [1][2].

[1] ssl3_get_record:decryption failed or bad record mac
[2] ssl3_read_bytes:sslv3 alert bad record mac

Modifications:
- SslHandler#unwrap updates buffer indexes on each iteration so that if
  reentry scenario happens the correct indexes will be visible.

Result:
Fixes https://github.com/netty/netty/issues/11146

Build project

Netty Project

Netty is an asynchronous event-driven network application framework for rapid development of maintainable high performance protocol servers & clients.

How to build

For the detailed information about building and developing Netty, please visit the developer guide. This page only gives very basic information.

You require the following to build Netty:

Note that this is build-time requirement. JDK 5 (for 3.x) or 6 (for 4.0+ / 4.1+) is enough to run your Netty-based application.

Branches to look

Development of all versions takes place in each branch whose name is identical to <majorVersion>.<minorVersion>. For example, the development of 3.9 and 4.1 resides in the branch '3.9' and the branch '4.1' respectively.

Usage with JDK 9+

Netty can be used in modular JDK9+ applications as a collection of automatic modules. The module names follow the reverse-DNS style, and are derived from subproject names rather than root packages due to historical reasons. They are listed below:

  • io.netty.all
  • io.netty.buffer
  • io.netty.codec
  • io.netty.codec.dns
  • io.netty.codec.haproxy
  • io.netty.codec.http
  • io.netty.codec.http2
  • io.netty.codec.memcache
  • io.netty.codec.mqtt
  • io.netty.codec.redis
  • io.netty.codec.smtp
  • io.netty.codec.socks
  • io.netty.codec.stomp
  • io.netty.codec.xml
  • io.netty.common
  • io.netty.handler
  • io.netty.handler.proxy
  • io.netty.resolver
  • io.netty.resolver.dns
  • io.netty.transport
  • io.netty.transport.epoll (native omitted - reserved keyword in Java)
  • io.netty.transport.kqueue (native omitted - reserved keyword in Java)
  • io.netty.transport.unix.common (native omitted - reserved keyword in Java)
  • io.netty.transport.rxtx
  • io.netty.transport.sctp
  • io.netty.transport.udt

Automatic modules do not provide any means to declare dependencies, so you need to list each used module separately in your module-info file.
