RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

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

Comment 4 lpeer 2015-12-23 07:57:38 UTC 
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.

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