sys/netinet6 : frag6.c
Log message:
frag6_input(): must always decrement counter when dropping fragment
Currently frag6_input() does not decrement counter in one case:
- it is processing fragment with offset 0 which arrives after
the last fragment (fragment with max. offset)
- there are more IPv6 extension headers between IPv6 header
and IPv6 fragment header
- re-assembled packet exceeds IPV6_MAXPACKET size limit
if conditions above are met, then fragment gets dropped without
decrementing counters. This commit fixes that.
The issue was pointed out by Frank Denis.
