Description Piyush Bhoot 2015-06-11 12:10:07 UTC

Description of problem:

Type of Service (TOS) can generally not be set in a IPv6 header from Java when using TCP. Also for IPv4 some tweaks have to be performed in order to get all cases working. Extensive testing has been done for different cases. Please consider all these cases. Testing was done by collecting snoops and analyzing the resulting ip headers of the TCP and UDP communication between Java clients and servers.

Upstream bug has been filed to address this issue, which is in resolved state
https://bugs.openjdk.java.net/browse/JDK-8029607

This is will require a backport into OpenJDK7 which is now maintained by Red Hat.

Assigning to ahughes to investigate.

Comment 3 Andrew John Hughes 2015-06-12 15:33:38 UTC

No backport required; this is already upstream as part of 7u80, as shown on the bug.

t will appear in RHEL when we move to the 2.6.x series. Hopefully, this will be with 2.6.1 in the July CPU.
