Looking at do_output, it appears that we silently drop a packet if a bad
out_port was specified because vport will be NULL from ovs_vport_rcu and we
just free the skb and return from thereon. Instead, an ideal behavior should
be to log this in user space via log_execute_message and also

Hi,
I see that in ovs-2.3 onwards, we use format_uint32_masked from
match_format for printing register values. While use of format_uint32_masked
for printing recirc_id, dp_hash and pkt_mark are fine, register values can
have a legit value of 0. As format_uint32_masked uses %#x, we may end up
Hi,
I'm trying to set up BFD between two vlans created on different bridges
running on different hosts. I noticed that unless bfd:bfd_remote_dst_mac is
specified while setting up the BFD, the packet never leaves the host switch
due to skipping output to input port. Looking at RFC 5880/5881,
. the bfd_remote_dst_mac
construct). Am I missing something here?

Hi,
I saw that bundle_destroy calls mbridge_unregister_bundle with bundle-aux.
However the second parameter of mbridge_unregister_bundle is ofbundle. When
creating the bundle in mbridge_bundle_register, we setup mbundle using
ofbundle. Shouldn't the call to unregister be just ofbundle
Hi,
Can anyone please let me know if Centos 7.1 (3.10.0-229) kernel supported in
master branch? I'm currently based off branch-2.3. If this is already
available, what would be the commit hash(es) to be picked up?
Thanks,

Hi Ben,
It's a little unconventional for us to use a wall clock time for this.
I'd be more inclined to report it as N seconds ago or N ms ago. Any
particular reason to use a wall clock time?
I've seen that all BFD other outputs use now -/+ convention, but just that

Can this patch be considered? We keep hitting it in our data center where a
number of fresh installed EL7 hosts fail to boot up due to default selinux
permissions, but ovs should not prevent the system to bootup to multiuser..

It seems we just need to extract the text between the table name and the first
blank line below it. this should pretty easy with either awk or sed.
As for efficiency, the db files I have access to are sufficiently
small that the script should work in practise,
especially used only for
a transaction only
for that table instead of all, and then print the response for that

We recently came across a case where ovs trips due to a bad function pointer
because of a possible corruption in ovs rcu cbset. This typically happens if
we have 100+ VMs with ~1000 flows.
