Disable IPv6 RAs & Autoconf For All (Not Just Default)
The current kernel sysctl settings modify the net.ipv6.conf.default.accept_ra and net.ipv6.conf.default.autoconf to both be '0'. However, this is overridden by the settings in net.ipv6.conf.all, so no matter what setting is in the ifcfg file for the IPv6 interface, autoconfiguration and accept_ra will be enabled. This causes a security vulnerability where rogue RAs could be used to intercept traffic from the controllers. This change sets both default and all settings to '0' for IPv6 accept_ra and autoconf. Closes-Bug: 1632830 Change-Id: I95b86c5c6feed30dfa5103ffbddb9e85ac567bbb
