Replacing the missing hex prefix format specifier flag used for routing
table creation (tables missing from previous related commit)
Bug #61 http://bugzilla.vyos.net/show_bug.cgi?id=61
|
|
Update src/lbdecision.cc to maintain style consistency
|
|
Offset the fwmarks used in load-balancing to avoid conflicts with
routing tables created by policy based routing. Originally from
Benjamin Beret.

This reverts commit e9001877d3bbdd5c4c48f0ccc088bd381d0b92dc.
Since the upstream change in the kernel from 3.6 onwards, where the
ipv4 routing cache has has been removed due to performance
bottlenecks and the fact that it was reasonable easy to launch denial
of service attackes (it was designed in friendlier times), the kernel
now reverts back to round-robin per packet routing rather than per flow
as it was previously, with the result that this commits breaks
load-balancing with two active routes.

When checking policy route compare nexthop and interface rather then just checking for an entry. This allows for incorrect entries to be replaced. This would be
a problem if different nexthop is readvertised via dhcp to the interface.

This is due to the output mangle table being processed after reachability determination for locally sourced routes.
Note that routes will still be subject to routing by WLB (provided they match the WLB rule set).

that for this behavior to be active in WLB nexthop needs to be populated with 'dhcp' configuration string.

note: the one todo item for this feature is to add "stickiness" of an active interface. wlb re-evaluates all rules on an interface state change and this may cause the interface to change for failover mode. supporting this mode requires a less than trivial rewrite of the wlb decision code.:
