[Pkg-xen-devel] Bug#1067152: xen-utils-common: remove IPv6 link locals from switched interfaces

[Aleksi Suhonen]

Package: src:xen
Version: 4.17.3+10-g091466ba55-1~deb12u1
Severity: wishlist

I wasn't sure if this script comes from Debian or Xen or somewhere else, 
so I thought it safest to report it here.

IPv6 on the Dom0 should be removed from switched/bridged interfaces. 
Earlier I would just sysctl disable_ipv6 on the interface, but the below 
diff seems to remove the link local address too. I've attached the full 
fixed file as well.

       ip address flush dev ${dev}
