ERROR DESCRIPTION:
TCPIP machine loops when RouteD is started. Looking at the
traces it was determined that TCPIP is looping in TCTREEP
in procedure FillIpRoutingKey. This code was rewritten in APAR
PQ46571 (and sysroute APAR PQ50059).
Problem is in base code for VM TCP/IP R420.
LOCAL FIX:
PROBLEM SUMMARY:
****************************************************************
* USERS AFFECTED: All TCP/IP users. *
****************************************************************
* PROBLEM DESCRIPTION: TCPIP machine loops when processing the *
* GATEWAY statement or when starting up *
* RouteD or MPRoute. *
****************************************************************
* RECOMMENDATION: APPLY PTF *
****************************************************************
TCP/IP is looping in the FillIpRoutingKey procedure (TCTREEP)
while trying to determine the routing key.
PROBLEM CONCLUSION:
The subnetmask and the class mask are used to determine the
routing key. They are declared to be unsignedintegertype, but
the assembler instructions generated are treating them as signed
fields. This causes TCPIP to loop.
The code was changed to call an assembler routine COMPLOGC for
all the subnetmasks comparisons.
