From 73f5698e77219bfc3ea1903759fe8e20ab5b285e Mon Sep 17 00:00:00 2001 From: Stefan Tomanek Date: Sat, 3 Aug 2013 14:14:43 +0200 Subject: fib_rules: fix suppressor names and default values This change brings the suppressor attribute names into line; it also changes the data types to provide a more consistent interface. While -1 indicates that the suppressor is not enabled, values >= 0 for suppress_prefixlen or suppress_ifgroup reject routing decisions violating the constraint. This changes the previously presented behaviour of suppress_prefixlen, where a prefix length _less_ than the attribute value was rejected. After this change, a prefix length less than *or* equal to the value is considered a violation of the rule constraint. It also changes the default values for default and newly added rules (disabling any suppression for those). Signed-off-by: Stefan Tomanek Signed-off-by: David S.
