DB2 FOR LUW / DB2FORLUW / B10 - DB2

Db2 tools accessing network interface (NIC) information,
db2haicu and db2instance, might fail with a segmentation fault
(memory fault/SEGV), if:
- there is a NIC, which doesn't have an IPv4 address assigned
or:
- there is no routes associated with one of the interfaces

For db2haicu, tool will fail on network configuration stage
(e.g. network tiebreaker setup), for db2instance, "db2instance
-list" will be affected.
If system is configured to dump a core (ulimit -c unlimited),
the core dump will show the following functions on the top of
the stack:
db2haicu:
sqlhaGetInfoForClusterObject
sqlhaUIListAllNICsInClus

db2instance:
sqlhaGetInfoForClusterObject
sqlhaCheckNetworkAdapterOnHost

Db2 V11.1 Mod3 Fix Pack 3 and both iFix001 and iFix002 are the
only V11.1 Fix Packs affected.
