2015-07-21fib: Add fib rule match on tunnel idThomas Graf1-1/+1
This add the ability to select a routing table based on the tunnel id which allows to maintain separate routing tables for each virtual tunnel network. ip rule add from all tunnel-id 100 lookup 100 ip rule add from all tunnel-id 200 lookup 200 A new static key controls the collection of metadata at tunnel level upon demand.

2013-08-03fib_rules: fix suppressor names and default valuesStefan Tomanek1-1/+1
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 <stefan.tomanek@wertarbyte.de> Signed-off-by: David S.

2013-08-03fib_rules: add route suppression based on ifgroupStefan Tomanek1-1/+1
This change adds the ability to suppress a routing decision based upon the interface group the selected interface belongs to. This allows it to exclude specific devices from a routing decision.

2013-08-01fib_rules: add .suppress operationStefan Tomanek1-1/+1
This change adds a new operation to the fib_rules_ops struct; it allows the suppression of routing decisions if certain criteria are not met by its results. The first implemented constraint is a minimum prefix length added to the structures of routing rules. If a rule is added with a minimum prefix length >0, only routes meeting this threshold will be considered. Any other (more general) routing table entries will be ignored. When configuring a system with multiple network uplinks and default routes, it is often convinient to reference the main routing table multiple times - but omitting the default route. Using this patch and a modified "ip" utility, this can be achieved by using the following command sequence: $ ip route add table secuplink default via 10.42.23.1 $ ip rule add pref 100 table main prefixlength 1 $ ip rule add pref 150 fwmark 0xA table secuplink With this setup, packets marked 0xA will be processed by the additional routing table "secuplink", but only if no suitable route in the main routing table can be found. By using a minimal prefixlength of 1, the default route (/0) of the table "main" is hidden to packets processed by rule 100; packets traveling to destinations with more specific routing entries are processed as usual.
