application confirms the connection
with this version, it does not match
with what the kernel has in its
structure. This causes an abort to be
sent to the initiator of the connection.
Resolution Code has been modified so that the
kernel passes the correct session
version to the user application.

Symptom Kernel stack overflow when OTS is
used with mbuf based lan drivers.
Defect Description The stack overflow occurs in the
following situations.
a) If a dynamic NSAP is deleted when
applications are registered on that
NSAP and are in data transfer state
over the associated connections.
b) Due to a bad OTS configuration,
where the machine has been
configured as a default IS.This would
be a bad configuration since OTS
cannot be configured as an IS.
In both the cases, the incoming CLNP
PDU would get locked up between the
DLPI layer and OTS CLNP layer.
When the PDU was finally freed, it
resulted in the kernel stack overflow,
due to the chain of streamsbuffers and
mbufs that had to be freed.
Resolution a) For the first case, when deleting
dynamic NSAP, code is modified to
remove the routing information entry
for that NSAP, so that forwarding the
PDU to the local system is avoided
