pf tests: pfsync and route_to test case
Test pfsync in a more realistic scenario with carp and route_to rules. Build this topology and initiate a single ping session from client to server: ┌──────┐ │client│ └───┬──┘ │ ┌───┴───┐ │bridge0│ └┬─────┬┘ │ │ ┌────────────────┴─┐ ┌─┴────────────────┐ │gw_route_to_master├─┤gw_route_to_backup│ └────────────────┬─┘ └─┬────────────────┘ │ │ ┌┴─────┴┐ │bridge1│ └┬─────┬┘ │ │ ┌────────────────┴─┐ ┌─┴────────────────┐ │gw_reply_to_master├─┤gw_reply_to_backup│ └────────────────┬─┘ └─┬────────────────┘ │ │ ┌┴─────┴┐ │bridge2│ └───┬───┘ │ ┌───┴──┐ │server│ └──────┘ gw* jails forward traffic through pf route-to rules, not fib lookups. If backup_promotion arg is given (as in the pfsync_pbr test case), a carp failover event occurs during the ping session on both gateways. Verify that ping messages still go where we expect them to go. MFC after: 2 weeks Sponsored by: Orange Business Services
