Hi all,
I have been looking around in ip6.c how the MIB counters are being
handled and I ran into a couple of issues with InDelivers:
In ip_rput_data_v6, when a packet is send up to SCTP the InDelivers
counter in ip_mib is incremented rather than the one in ill_ip6_mib. I
cannot see any reason why this is the case.
Secondly, when a multicast packet is being processed, the InDelivers
counter is incremented each time a "matching" connection is found. So
the reception of a single packet may increment the counter by more than
one, which seems rather odd. The description of the counter itself is
"the number of datagrams successfully delivered to the IP
user-protocols", so in the case multicast it seems to me that InDelivers
counter should only be incremented once as the packet is sent up to the
next protocol level (if then multiple UDP endpoints get a copy of the
packet should not matter.) What do you guys think?
Anders
