Eric Anderson 8a25c35939 Filter user-provided ciphers using RFC cipher names
Motivation:

Previously filterCipherSuites was being passed the OpenSSL-formatted
cipher names. Commit 43ae974 introduced a regression as it swapped to the
RFC/JDK format, except that user-provided ciphers were not converted and
remained in the OpenSSL format.

This mis-match would cause all user-provided to be thrown away, leading
to failure trying to set zero ciphers:
Exception in thread "main" javax.net.ssl.SSLException: failed to set cipher suite: []
	at io.netty.handler.ssl.ReferenceCountedOpenSslContext.<init>(ReferenceCountedOpenSslContext.java:299)

	at io.netty.handler.ssl.SslContext.newServerContextInternal(SslContext.java:421)
	at io.netty.handler.ssl.SslContextBuilder.build(SslContextBuilder.java:441)
Caused by: java.lang.Exception: Unable to configure permitted SSL ciphers (error:100000b1:SSL routines:OPENSSL_internal:NO_CIPHER_MATCH)
	at io.netty.internal.tcnative.SSLContext.setCipherSuite(Native Method)
	at io.netty.handler.ssl.ReferenceCountedOpenSslContext.<init>(ReferenceCountedOpenSslContext.java:295)
	... 7 more

Modifications:

Remove the reformatting of user-provided ciphers, as they are already in
the RFC/JDK format.

Result:

No regression, and the internals stay sane using the RFC/JDK format.

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+) 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 4.0 resides in the branch '3.9' and the branch '4.0' respectively.
