            Bug ID: 29415
           Summary: getaddrinfo with AI_ADDRCONFIG returns addresses with
                    wrong family
           Product: glibc
           Version: 2.35
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: nscd
          Assignee: unassigned at sourceware dot org
          Reporter: fabian@ritter-vogt.de

  Target Milestone: ---

Processes cache network interface information such as whether IPv4 or IPv6
are enabled. This is only checked again if the "netlink timestamp" provided
by nscd changed, which is triggered by netlink socket activity.

However, this mechanism is currently broken. This means that e.g. processes
which started before network configuration got unusuable addresses from
getaddrinfo, like IPv6 only even though only IPv4 is available:
