example of adjacent ranges causing error
After upgrading kernel from 5.5 to 5.6.2 our ruleset which includes mapping
packet sizes to counters fails to load. Problem is in adjacent ranges:
This fails (with File exists message):
counter name ip length map { 0-100 : "c1", 101-200 : "c2" }
After increasing start of second range by one it loads ok:
counter name ip length map { 0-100 : "c1", 102-200 : "c2" }
See attached examples.
Probably same bug as:
