Ben Pfaff [Fri, 13 Jul 2012 06:08:45 +0000 (23:08 -0700)]
debian: Do not change iptables rules by default.

Debian kernel maintainer Bastian Blank writes, at
http://bugs.debian.org/680537:

   The netfilter rules are a shared resource. There is no synchronization,
   so the admin have the last word. As kernel maintainer, I see it similar
   to a configuration file, so Â§10.7 policy applies.

   The purpose of openvswitch is to provide support for switching, not to
   setup filter rules. This means it violates the principle of least
   surprise.

I believe that the argument by analogy to configuration files is weak,
given that the Debian policy section in question is very specifically about
files, not about general principles.  On the other hand, Debian does not
install any firewall by default, so the presence of a rule that blocks GRE
traffic is a sign that the administrator has taken an explicit action to
install a firewall that blocks GRE, and therefore it is rather rude to
override this.  Therefore, this patch simply turns off this behavior on
Debian, given that in ordinary Debian installations it will have no
adverse effect on Open vSwitch.

table is 0 anyhow.

OpenFlow 1.3 is explicit:

    The action list of an OFPT_PACKET_OUT message can also specify the
    OFPP_TABLE reserved port as an output action to process the packet
    through the existing flow entries, starting at the first flow table.

ovs-ofctl: Avoid use-after-free upon "ofctl/unblock" when connection dies.

The implementation of "ofctl/block" used a nested poll loop, with an inner
call to unixctl_server_run().  This poll loop always ran inside an outer
call to unixctl_server_run(), since that's the context within which unixctl
command implementations run.  That means that, if a unixctl connection got
closed within the inner poll loop, and the outer poll loop happened to be
processing the same unixctl connection, then the outer poll loop would
dereference data in the freed connection.

The simplest solution is to avoid a nested poll loop, so that's what this
commit does.

12 years agoovs-ofctl: Use the prepared connection to dump flows in do_dump_flows__().
Ben Pfaff [Tue, 3 Jul 2012 17:25:35 +0000 (10:25 -0700)]
ovs-ofctl: Use the prepared connection to dump flows in do_dump_flows__().

The logic in do_dump_flows__() went to some trouble to open an OpenFlow
connection and set the correct protocol, but then it allowed
dump_stats_transaction() to create and use a completely different OpenFlow
connection that hadn't been prepared that way.  This commit fixes the
problem.

I don't think that there is a real bug here because currently the set of
protocols doesn't influence flow stats replies.  But that could change in
the future.

datapath: Check gso_type for correct sk_buff in queue_gso_packets().

At the point where it was used, skb_shinfo(skb)->gso_type referred to a
post-GSO sk_buff.  Thus, it would always be 0.  We want to know the pre-GSO
gso_type, so we need to obtain it before segmenting.

Before this change, the kernel would pass inconsistent data to userspace:
packets for UDP fragments with nonzero offset would be passed along with
flow keys that indicate a zero offset (that is, the flow key for "later"
fragments claimed to be "first" fragments).  This inconsistency tended
to confuse Open vSwitch userspace, causing it to log messages about
"failed to flow_del" the flows with "later" fragments.
