Description of problem:

irc #openvswitch

[15:59:14]  <marcelo-amaral> hi

[16:01:21]  <marcelo-amaral> I saw here: http://openvswitch.org/pipermail/discuss/2015-March/017097.html that OVS does not support yet modifying the type or code in ICMP. Is it still true?

[16:02:06]  <shettyg1> marcelo-amaral: True.

[16:02:56]  <marcelo-amaral> Is there any way to turn around this limitation?

[16:03:41]  <marcelo-amaral> I want to create of rules for ICMP reply

[16:03:54]  <shettyg1> Quick counter question. You want OVS to ICMP reply to you?

[16:04:36]  <shettyg1> I suppose this is for L3 router interface?

[16:05:49]  <marcelo-amaral> Yes, when we create a virtual router in openstack, the default gateway does not respond ping

[16:06:30]  <marcelo-amaral> So, it is required to create a specific rule to deal with it

[16:11:28]  <marcelo-amaral> shettygl: do you have any idea how I could create icmp reply? If it is possible

[16:24:03]  <marcelo-amaral> blp: hi

[16:24:21]  <blp> marcelo-amaral: hi

[16:25:54]  <marcelo-amaral> blp: I am trying to create a icmp reply rule, but I saw that OVS does not support yet modifying the type or code in ICMP. Do you now, if there is a way to do it, or if ovs will support it?

[16:30:12]  <blp> marcelo-amaral: It would not be hard to add, so we'd probably accept a patch to do it.

[16:30:29]  <blp> It would require some care in use, since a lot of ICMP types don't have compatible payloads.

[16:46:16]  <marcelo-amaral> blp: thank you, I will try to take a look in the code.

[16:49:28]  <marcelo-amaral> blp: could you please point in the code, where is it?

[16:49:50]  <blp> marcelo-amaral: Where is what?

[16:50:33]  <marcelo-amaral> blp: the logic that block modifying the type or code in ICMP

[16:50:46]  <jiuweigui> Hi. Are there any good book about openvswitch or sdns that you'd recommend?

[16:51:35]  <blp> marcelo-amaral: meta-flow.h, change access from read-only to read/write for those fields

[16:52:03]  <marcelo-amaral> blp: perfect! thank you very much

OVS support for setting icmp type/code is in the works:
Comment 4 lpeer 2015-12-23 02:57:38 EST
fbl - can we get this patch in OVS 2.4? we need it to be able to pass scenario tests in OpenStack deployment (OSP-8) that is using ODL as the networking driver.

> fbl - can we get this patch in OVS 2.4?

We plan to update to 2.5 very soon which includes the patch.
Does that work for you?
