    Fix sysctl settings for neutron on CentOS

    We should make sure the following settings are configured
    /etc/sysctl.conf file on compute nodes in case we use neutron:

    net.bridge.bridge-nf-call-arptables = 1
    net.bridge.bridge-nf-call-iptables = 1
    net.bridge.bridge-nf-call-ip6tables = 1

    Otherwise security groups functionality may be broken after
    executing 'sysctl -p' on compute nodes.

This one requires an additional update of release notes for 5.1.1 (since we don't have a tag for 5.1.1 yet)

Looks similar to

where to put this? dev-docs or fuel-docs?

[Sheena Conant (sheena-conant)]

The ask for this is not clear to me. Is this a workaround that users setting up Neutron with CentOS need to be aware of?

[Svetlana Karslioglu (skarslioglu)]

This looks like something that has been relevant to 5.1 release notes. I think it does not affect other release notes.

[Alexey Stupnikov (astupnikov)]

MOS5.1 and MOS6.0 no longer supported, moving to Won't Fix.

[Alexey Stupnikov (astupnikov)]

We no longer support MOS5.1, MOS6.0, MOS6.1
We deliver only Critical/Security fixes to MOS7.0, MOS8.0.
We deliver only High/Critical/Security fixes to MOS9.2.
