Problem conclusion

Temporary fix

Comments

• This APAR enhanced z/OS Communications Server to provide
  network support for IBM z/OS Container Platform.  It provides
  support for LE and Unix System Services (USS) Callable
  Services APIs, as well as System Resolver APIs and the
  Netstat application.
  .
  - The getsockopt() and setsockopt() LE APIs and BPX1OPT and
  BPX4OPT USS APIs are enhanced to support a new option to
  retrieve and set the time-to-live field in the IP header that
  is used for every packet sent from the TCP or UDP socket
  connection.
  - New support is added for the clone(), unshare() and setns()
  LE APIs and BPX1CLN, BPX1UNS, and BPX1SNS USS APIs to
  create/join a Unix Time Sharing (UTS) namespace for a USS
  process.
  - The gethostname() LE API, BPX1HST and BPX4HST USS APIs and
  System Resolver APIs are enhanced to support the UTS namespace
  and to retrieve the hostname associated with that namespace.
   - New support is added for the sethostname() LE API and BPX1HST
  and BPX4HST USS APIs to set the hostname for a USS process with
  a UTS namespace.
  - System Resolver is enhanced to change the search order for
  resolver configuration for USS processes using the z/OS
  Container Platform.
  - Netstat is enhanced to display network information specific
  to the container where the netstat command is issued.
  - New VIPARANGE type is added to provide network access to a
  pod or a container that runs on z/OS Container Platform.
