For instance, if we enable promiscuous mode, then enable and disable allmulti, then the promiscuous mode is wrongly disabled. Fix this behavior by: - doing nothing when we set/unset allmulti if promiscuous mode is on - restorting the proper mode (none or allmulti) when we disable promiscuous mode Fixes: 1f4564ed7696 ("net/ixgbevf: enable promiscuous mode") Signed-off-by: Olivier Matz --- Hi, For reference, this was tested with this plan: echo 8 > "/sys/bus/pci/devices/0000:01:00.1/sriov_numvfs" ip link set dev eno2 up ip link set dev eno2 promisc on bridge link set dev eno2 hwmode veb ip link set dev eno2 mtu 9000 ip link set dev eno2 vf 0 mac ac:1f:6b:fe:ba:b0 ip link set dev eno2 vf 0 spoofchk off ip link set dev eno2 vf 0 trust on ip link set dev eno2 vf 1 mac ac:1f:6b:fe:ba:b1 ip link set dev eno2 vf 1 spoofchk off ip link set dev eno2 vf 1 trust on python3 usertools/dpdk-devbind.py -s python3 usertools/dpdk-devbind.py -b vfio-pci 0000:01:10.1 # vf 0 python3 usertools/dpdk-devbind.py -b ixgbevf 0000:01:10.3 # vf 1 # in another terminal scapy while True: sendp(Ether(dst='ac:1f:6b:00:00:00'), iface='eno2v1') # wrong mac sendp(Ether(dst='ac:1f:6b:fe:ba:b0'), iface='eno2v1') # correct mac time.sleep(1) ./build/app/dpdk-testpmd -l 1,2 -a 0000:01:10.1 -- -i --total-num-mbufs=32768 show port info all set fwd rxonly set verbose 1 set promisc all off set allmulti all off start # ok, only packets to dst='ac:1f:6b:fe:ba:b0' are received # ok, both packets are received set promisc all on # nok, only packets to dst='ac:1f:6b:fe:ba:b0' are received set allmulti all on set allmulti all off drivers/net/ixgbe/ixgbe_ethdev.c | 12 +++++++++++- 1 file changed, 11 insertions(+), 1 deletion(-) diff --git a/drivers/net/ixgbe/ixgbe_ethdev.c b/drivers/net/ixgbe/ixgbe_ethdev.c index 8cec951d94..cc8383c5a9 100644 --- a/drivers/net/ixgbe/ixgbe_ethdev.c +++ b/drivers/net/ixgbe/ixgbe_ethdev.c @@ -7785,9 +7785,13 @@ static int ixgbevf_dev_promiscuous_disable(struct rte_eth_dev *dev) { struct ixgbe_hw *hw = IXGBE_DEV_PRIVATE_TO_HW(dev->data->dev_private); + int mode = IXGBEVF_XCAST_MODE_NONE; int ret; - switch (hw->mac.ops.update_xcast_mode(hw, IXGBEVF_XCAST_MODE_NONE)) { + if (dev->data->all_multicast) + mode = IXGBEVF_XCAST_MODE_ALLMULTI; + + switch (hw->mac.ops.update_xcast_mode(hw, mode)) { case IXGBE_SUCCESS: ret = 0; break; @@ -7809,6 +7813,9 @@ ixgbevf_dev_allmulticast_enable(struct rte_eth_dev *dev) int ret; int mode = IXGBEVF_XCAST_MODE_ALLMULTI; + if (dev->data->promiscuous) + return 0; + switch (hw->mac.ops.update_xcast_mode(hw, mode)) { case IXGBE_SUCCESS: ret = 0; @@ -7830,6 +7837,9 @@ ixgbevf_dev_allmulticast_disable(struct rte_eth_dev *dev) struct ixgbe_hw *hw = IXGBE_DEV_PRIVATE_TO_HW(dev->data->dev_private); int ret; + if (dev->data->promiscuous) + return 0; + switch (hw->mac.ops.update_xcast_mode(hw, IXGBEVF_XCAST_MODE_MULTI)) { case IXGBE_SUCCESS: ret = 0; -- 2.30.2
