The following commit should be backported: commit 666cdc506f0fb540f123a9ce3d8585b5e9cb9698 Author: Tom Herbert <therbert> Date: Fri Nov 7 08:05:34 2014 -0800 vxlan: Add support for enabling UDP checksums Add udpcsum option to enable transmitting UDP checksums when doing VXLAN/IPv4. Add udp6zerocsumtx, and udp6zerocsumrx options to enable sending zero checksums and receiving zero checksums in VXLAN/IPv6. Signed-off-by: Tom Herbert <therbert> Hi Ramu, (In reply to Ramu Ramamurthy from comment #0) > THe rhel 7.1 vxlan driver has support for the "udpcsum" attribute but the > iproute shipped with the RHEL 7.1 does not have support to provision that > option on vxlan links. > > This bug requests to backport that "udpcsum" attribute to the iproute > package shipped with RHEL 7.1 I see the above commit is present in RHEL7.2 already. Can you confirm updating to RHEL7.2 is not a solution for you and instead we should backport the requested functionality to RHEL7.1? Thanks, Phil Hi Phil, if support is there in rhel7.2, then, you can close this, We dont need it in RHEL7.1 specifically, (In reply to Ramu Ramamurthy from comment #4) > Hi Phil, > > if support is there in rhel7.2, then, you can close this, We dont need it in > RHEL7.1 specifically, OK. I just verified functionality on a RHEL7.2 testing machine with iproute-3.10.0-54.el7.x86_64: # ip link add vxlan0 type vxlan id 1 udpcsum vxlan: destination port not specified Will use Linux kernel default (non-standard value) Use 'dstport 4789' to get the IANA assigned value Use 'dstport 0' to get default and quiet this message # ip -d link show vxlan0 72: vxlan0: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN mode DEFAULT qlen 1000 link/ether 6e:d2:0b:a4:1b:47 brd ff:ff:ff:ff:ff:ff promiscuity 0 vxlan id 1 srcport 0 0 dstport 8472 ageing 300 udpcsum addrgenmode eui64 # ip link del vxlan0 # ip link add vxlan0 type vxlan id 1 noudpcsum vxlan: destination port not specified Will use Linux kernel default (non-standard value) Use 'dstport 4789' to get the IANA assigned value Use 'dstport 0' to get default and quiet this message # ip -d link show vxlan0 71: vxlan0: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN mode DEFAULT qlen 1000 link/ether 26:34:fe:4b:0b:35 brd ff:ff:ff:ff:ff:ff promiscuity 0 vxlan id 1 srcport 0 0 dstport 8472 ageing 300 addrgenmode eui64 So if 'udpcsum' was specified upon link creation, it is later printed by 'ip -d link show'. Assuming this is the requested feature, I'm closing this ticket now. Feel free to reopen in case my assumption is wrong. Thanks, Phil |
