[Kernel-packages] [Bug 1967856] Re: Hairpin traffic does not work with centralized NAT gw
** Changed in: openvswitch (Ubuntu Impish) Status: New => Won't Fix ** Changed in: ovn (Ubuntu Impish) Status: New => Won't Fix -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1967856 Title: Hairpin traffic does not work with centralized NAT gw Status in linux package in Ubuntu: Invalid Status in openvswitch package in Ubuntu: Invalid Status in ovn package in Ubuntu: Invalid Status in linux source package in Focal: Fix Released Status in openvswitch source package in Focal: Invalid Status in ovn source package in Focal: Invalid Status in linux source package in Impish: Won't Fix Status in openvswitch source package in Impish: Won't Fix Status in ovn source package in Impish: Won't Fix Status in linux source package in Jammy: Fix Released Status in openvswitch source package in Jammy: Invalid Status in ovn source package in Jammy: Invalid Status in linux source package in Kinetic: Invalid Status in openvswitch source package in Kinetic: Invalid Status in ovn source package in Kinetic: Invalid Bug description: [Impact] Users of Open vSwitch on Focal will not be able to upgrade to v2.16.0 or newer until this long standing kernel bug has been fixed. Users of Open vSwitch on Jammy will be affected by this bug and have no user space fix available. This bug currently blocks the OpenStack Engineering team's charm product gate. [Test Plan] Execute the OVN system testsuite utilizing the kernel data path with the test synthesis patch in comment #7 applied. In addition to that validating that the OpenStack charm test gate is unblocked would be valuable. [Regression Potential] The regression potential can be considered as low because: - The calls added in the openvswitch kernel datapath code would prior to Open vSwitch 2.16.0 have been initiated from the userspace code and by chance concealed this bug. - After an optimization done in 2.16.0 the kernel bug was revealed and these calls now must be made from the kernel datapath to retain functionality in use in the wild. [Original Bug Description] If you have two hvs where hv1 is the gateway chassis and you have an instance running on hv2. On instance on hv2 hairpin traffic works for the first session, but not for the next: $ ping -c1 10.78.95.89 PING 10.78.95.89 (10.78.95.89) 56(84) bytes of data. 64 bytes from 10.78.95.89: icmp_seq=1 ttl=62 time=1.07 ms --- 10.78.95.89 ping statistics --- 1 packets transmitted, 1 received, 0% packet loss, time 0ms rtt min/avg/max/mdev = 1.078/1.078/1.078/0.000 ms $ sudo ovs-appctl -t ovs-vswitchd dpctl/dump-conntrack icmp,orig=(src=10.78.95.89,dst=192.168.0.211,id=7334,type=8,code=0),reply=(src=192.168.0.211,dst=10.78.95.89,id=7334,type=0,code=0),zone=7 icmp,orig=(src=192.168.0.211,dst=10.78.95.89,id=7334,type=8,code=0),reply=(src=10.78.95.89,dst=192.168.0.211,id=7334,type=0,code=0),zone=7 $ ping -c1 10.78.95.89 PING 10.78.95.89 (10.78.95.89) 56(84) bytes of data. --- 10.78.95.89 ping statistics --- 1 packets transmitted, 0 received, 100% packet loss, time 0ms $ sudo ovs-appctl -t ovs-vswitchd dpctl/dump-conntrack icmp,orig=(src=10.78.95.89,dst=192.168.0.211,id=7334,type=8,code=0),reply=(src=192.168.0.211,dst=10.78.95.89,id=7334,type=0,code=0),zone=7 icmp,orig=(src=192.168.0.211,dst=10.78.95.89,id=7334,type=8,code=0),reply=(src=10.78.95.89,dst=192.168.0.211,id=7334,type=0,code=0),zone=7 icmp,orig=(src=192.168.0.211,dst=10.78.95.89,id=7335,type=8,code=0),reply=(src=10.78.95.89,dst=192.168.0.211,id=7335,type=0,code=0),zone=7 We made an attempt at using OVN built with [0], but that did unfortunately not help.

[Kernel-packages] [Bug 1967856] Re: Hairpin traffic does not work with centralized NAT gw
** Description changed: - If you have two hvs where hv1 is the gateway chassis and you have an - instance running on hv2. + [Impact] + Users of Open vSwitch on Focal will not be able to upgrade to v2.16.0 or newer until this long standing kernel bug has been fixed. + + Users of Open vSwitch on Jammy will be affected by this bug and + have no user space fix available. This bug currently blocks the + OpenStack Engineering team's charm product gate. + + [Test Plan] + Execute the OVN system testsuite utilizing the kernel data path with the test synthesis patch in comment #7 applied. + + In addition to that validating that the OpenStack charm test gate is + unblocked would be valuable. + + [Regression Potential] + The regression potential can be considered as low because: + - The calls added in the openvswitch kernel datapath code would + prior to Open vSwitch 2.16.0 have been initiated from the + userspace code and by chance concealed this bug. + - After an optimization done in 2.16.0 the kernel bug was + revealed and these calls now must be made from the kernel + datapath to retain functionality in use in the wild. + + [Original Bug Description] + If you have two hvs where hv1 is the gateway chassis and you have an instance running on hv2.

This bug is awaiting verification that the linux/5.15.0-43.46 kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-jammy' to 'verification-done-jammy'. If the problem still exists, change the tag 'verification-needed-jammy' to 'verification-failed-jammy'. If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed.

This issue has been fixed by a patch to the openvswitch datapath code in the kernel [0]. The patched kernel would be required when used in conjunction with OVN 21.12 or newer, which translates to Focal (yoga UCA), Jammy and Kinetic. 0: https://lore.kernel.org/netdev/20220606221140.488984-1-i.maxim...@ovn.org/T/#u ** Also affects: linux (Ubuntu Kinetic) Importance: Undecided Status: Incomplete ** Also affects: openvswitch (Ubuntu Kinetic) Importance: High Status: Invalid ** Also affects: ovn (Ubuntu Kinetic) Importance: Undecided Status: Invalid ** Also affects: linux (Ubuntu Focal) Importance: Undecided Status: New ** Also affects: openvswitch (Ubuntu Focal) Importance: Undecided Status: New ** Also affects: ovn (Ubuntu Focal) Importance: Undecided Status: New ** Also affects: linux (Ubuntu Jammy) Importance: Undecided Status: New ** Also affects: openvswitch (Ubuntu Jammy) Importance: Undecided Status: New ** Also affects: ovn (Ubuntu Jammy) Importance: Undecided Status: New ** Changed in: ovn (Ubuntu Jammy) Status: New => Invalid ** Changed in: ovn (Ubuntu Focal) Status: New => Invalid ** Changed in: openvswitch (Ubuntu Jammy) Status: New => Invalid ** Changed in: openvswitch (Ubuntu Focal) Status: New => Invalid ** Tags added: apport-collected jammy uec-images ** Description changed: If you have two hvs where hv1 is the gateway chassis and you have an instance running on hv2.
