Verified that all needed fixes are present in the latest OCP 4.7.z.
Marking this bz as MODIFIED.

The bug referenced from the kernel commit above is https://bugzilla.redhat.com/show_bug.cgi?id=1877128
which was Fixed-in-version kernel-4.18.0-254.el8.

Comment 5 ffernand 2021-11-23 21:26:12 UTC
Ooops. No, that is not right.
While the kernel version is correct, openvswitch2.13-2.13.0-124.el8fdp.x86_64 does not include the fix needed:

* Thu Nov 18 2021 Open vSwitch CI <ovs-ci> - 2.13.0-139
- Merging upstream branch-2.13 [RH git: 37c2767bbd]
    Commit list:
    057a5b0708 ofproto-dpif-xlate: Fix check_pkt_larger incomplete translation.

Since OCP is using openvswitch2.13-2.13.0-124.el8fdp.x86_64, that needs to be updated to 139 still.

Re-opening the bz. Sorry about that.

Comment 7 ffernand 2021-11-23 22:35:15 UTC
Nope; I was not wrong. :P

Since this bz does not depend on bug 1935663 , it is actually accurate to set this as MODIFIED.
openvswitch2.13-2.13.0-124.el8fdp.x86_64 includes all that is needed here.

In summary, please ignore comments 5 and 6 above. :)
