Tonghao Zhang bd1903b7c4 net: openvswitch: add hash info to upcall ... When using the kernel datapath, the upcall don't include skb hash info relatived. That will introduce some problem, because the hash of skb is important in kernel stack. For example, VXLAN module uses it to select UDP src port. The tx queue selection may also use the hash in stack. Hash is computed in different ways. Hash is random for a TCP socket, and hash may be computed in hardware, or software stack. Recalculation hash is not easy. Hash of TCP socket is computed: tcp_v4_connect -> sk_set_txhash (is random) __tcp_transmit_skb -> skb_set_hash_from_sk There will be one upcall, without information of skb hash, to ovs-vswitchd, for the first packet of a TCP session. The rest packets will be processed in Open vSwitch modules, hash kept. If this tcp session is forward to VXLAN module, then the UDP src port of first tcp packet is different from rest packets. TCP packets may come from the host or dockers, to Open vSwitch. To fix it, we store the hash info to upcall, and restore hash when packets sent back. +---------------+ +-------------------------+ | Docker/VMs | | ovs-vswitchd | +----+----------+ +-+--------------------+--+ | ^ | | | | | | upcall v restore packet hash (not recalculate) | +-+--------------------+--+ | tap netdev | | vxlan module +---------------> +--> Open vSwitch ko +--> or internal type | | +-------------------------+ Reported-at: https://mail.openvswitch.org/pipermail/ovs-dev/2019-October/364062.html Signed-off-by: Tonghao Zhang <xiangxia.m.yue@gmail.com> Acked-by: Pravin B Shelar <pshelar@ovn.org> Signed-off-by: David S.
