2012-08-21add packet libraryFUJITA Tomonori
As discussed on the mailing list, there is no good packet library (parses and builds various protocol packets). dpkt isn't flexible enough (can't nicely handle stacked protocols such as vlan, mpls, gre). NOX's one is nice but released under GPL3. So we need our own packet library. Signed-off-by: FUJITA Tomonori <fujita.tomonori@lab.ntt.co.jp>

2012-07-30of1.2: handle unknown match field properlyFUJITA Tomonori

2012-07-28test: simplify integrated OVS test suiteFUJITA Tomonori
This patch simplifies integrated OVS test suite. Currently, we wait for a barrier response before moving to the next test. However, we don't need. The logic works like the following: sending a flow mod (deleting all the flows) sending a barrier sending a flow mod (set up a flow to test) sending a barrier sending a flow stats Then the reply handler for flow stats verifies the result and move to the next. You can run a test suite like: $ ryu-manager ~/git/ryu/ryu/tests/integrated/test_add_flow_v12_actions.py We can try two more suites: ryu/tests/integrated/test_add_flow_v10.py ryu/tests/integrated/test_add_flow_v12_matches.py Signed-off-by: FUJITA Tomonori <fujita.tomonori@lab.ntt.co.jp>

2012-07-13nxm: fix nxm to OFPMatch conversionFUJITA Tomonori
This fixes a bug that the conversion ignores dl_dst. Soheil Hassas Yeganeh reported a problem about simple_isolation: The problem is that the isolation service tries to install flow-entries for a specific src and dst (in SimpleIsolation._modflow_and_send_packet), but instead the nx match code installs flow-entries only with src addresses and ignores the dst. So, when I boot multiple vms, only one of them is reachable. For instance, assume that you have two VM's A and B. When a packet comes from the gw to A, it installs "gw->A: A's port", but the acutal installed rule is "gw: A's port". This works for A, but, when you boot B, it tries to install "gw->B: B's port", but the acutal rule to be installed is "gw: B's port". So, it always connect the gateway to only one VM at a time.
