12 years agoofproto-dpif: Fix tag caching for learned flows.
Ben Pfaff [Tue, 20 Mar 2012 22:26:57 +0000 (15:26 -0700)]
ofproto-dpif: Fix tag caching for learned flows.

This code in xlate_table_action() is supposed to tag flows in tables that
have special forms so that changes do not require revalidating every flow.
When rule->tag is nonzero, its value can be used, because we know in this
case that rule->cr.wc is the same as table->other_table->wc and that thus
rule->tag caches the return value of the rule_calculate_tag() expression.
When rule->tag is zero (a "catchall" rule) we need to calculate the tag
manually because we have no way to cache it in that case.

I discovered this bug by running an "hping3" between a couple of VMs plus
the following commands on OVS in the middle:

    ovs-ofctl del-flows br0
    ovs-ofctl add-flow br0 "table=0 actions=learn(table=1, \
              idle_timeout=600, NXM_OF_VLAN_TCI[0..11], \
              NXM_OF_ETH_DST[]=NXM_OF_ETH_SRC[], \
              output:NXM_OF_IN_PORT[], fin_idle_timeout=10), resubmit(,1)"
    ovs-ofctl add-flow br0 "table=1 priority=0 actions=flood"

Without this patch, flows don't get properly invalidated upon initial MAC
learning, so one sees warnings like the following:

    in_port(2),eth(src=50:54:00:00:00:05,dst=50:54:00:00:00:07),
    eth_type(0x0800),ipv4(src=192.168.0.1,dst=192.168.0.2,proto=6,tos=0,
    ttl=64,frag=no),tcp(src=13966,dst=0): inconsistency in subfacet
    (actions were: 3,0,1) (correct actions: 1)

This patch fixes the problem and thus avoids these warnings.

ofproto-dpif: Avoid segfault deleting facets that execute LEARN actions.

"ovs-ofctl del-flows <bridge>" can result in the following call path:

  delete_flows_loose() in ofproto.c
    -> collect_rules_loose() -- uses 'ofproto_node' inside 'struct rule'
    -> rule_destruct() in ofproto-dpif.c
      -> facet_revalidate()
        -> facet_remove()
          -> facet_flush_stats()
            -> facet_account()
              -> xlate_actions()
                -> xlate_learn_action()
                  -> ofproto_flow_mod() back in ofproto.c
                    -> modify_flow_strict()
                      -> collect_rules_strict() -- also uses 'ofproto_node'

which goes "boom" when we fall back up the call chain because the nested
use of ofproto_node steps on the outer use of ofproto_node.

This commit fixes the problem by refusing to translate "learn" actions
within facet_flush_stats(), breaking the doubled use.

Another possible approach would be to switch to another way to keep track
of rules in the flow_mod implementations, so that there'd be no fighting
over 'ofproto_node'.  But then "ovs-ofctl del-flows" might still leave some
flows around (ones created by "learn" actions as flows are accounted as
facets get deleted), which would be surprising behavior.  And it seems in
general a bad idea to allow recursive flow_mods; the consequences have not
been carefully thought through.

Before this commit, one can reproduce the problem by running an "hping3"
between a couple of VMs plus the following commands on OVS in the middle.
Sometimes you have to run them a few times:

    ovs-ofctl del-flows br0
    ovs-ofctl add-flow br0 "table=0 actions=learn(table=1, \
              idle_timeout=600, NXM_OF_VLAN_TCI[0..11], \
              NXM_OF_ETH_DST[]=NXM_OF_ETH_SRC[], \
              output:NXM_OF_IN_PORT[], fin_idle_timeout=10), resubmit(,1)"
    ovs-ofctl add-flow br0 "table=1 priority=0 actions=flood"

This commit has a side effect that leftover unaccounted packets no longer
update the timeouts in MAC learning actions in some cases, when the facets
that cause updates are deleted.  At most one second of updates should  be
lost.

netlink-socket: Increase Netlink socket receive buffer size.

Open vSwitch userspace can set up flows at a high rate, but it is somewhat
"bursty" in opportunities to set up flows, by which I mean that OVS sets up
a batch of flows, then goes off and does some other work for a while, then
sets up another batch of flows, and so on.  The result is that, if a large
number of packets that need flow setups come in all at once, then some of
them can overflow the relatively small kernel-to-user buffers.

This commit increases the kernel-to-user buffers from the default of
approximately 120 kB each to 1 MB each.  In one somewhat synthetic test
case that I ran based on an "hping3" that generated a load of about 20,000
new flows per second (including both requests and replies), this reduced
the packets dropped at the kernel-to-user interface from about 30% to none.
I expect that it will similarly improve packet loss in workloads where
flow arrival is not easily predictable.

(This has little effect on workloads generated by "ovs-benchmark rate"
because that benchmark is effectively "self-clocking", that is, a new flow
is triggered only by a reply to a request made earlier, which means that
the number of buffered packets at any given has a known, constant upper
limit.)

12 years agodebian: Avoid unit test failure when doing "unofficial" builds.
Ben Pfaff [Fri, 9 Mar 2012 22:20:54 +0000 (14:20 -0800)]
debian: Avoid unit test failure when doing "unofficial" builds.

The configure option --with-build-number=0 is interpreted differently in
different places.  The configure script itself accepts 0 as an actual
build number and puts '#define BUILDNR "+build0"' into config.h.  The
code in python/automake.mk treats 0 as "no build number" and puts
'BUILDNR = ""' into version.py.

This commit avoids the problem by not passing 0 as a build number.
