2018-11-23net: thunderx: set tso_hdrs pointer to NULL in nicvf_free_snd_queueLorenzo Bianconi
Reset snd_queue tso_hdrs pointer to NULL in nicvf_free_snd_queue routine since it is used to check if tso dma descriptor queue has been previously allocated. The issue can be triggered with the following reproducer: $ip link set dev enP2p1s0v0 xdpdrv obj xdp_dummy.o $ip link set dev enP2p1s0v0 xdpdrv off [ 341.467649] WARNING: CPU: 74 PID: 2158 at mm/vmalloc.c:1511 __vunmap+0x98/0xe0 [ 341.515010] Hardware name: GIGABYTE H270-T70/MT70-HD0, BIOS T49 02/02/2018 [ 341.521874] pstate: 60400005 (nZCv daif +PAN -UAO) [ 341.526654] pc : __vunmap+0x98/0xe0 [ 341.530132] lr : __vunmap+0x98/0xe0 [ 341.533609] sp : ffff00001c5db860 [ 341.536913] x29: ffff00001c5db860 x28: 0000000000020000 [ 341.542214] x27: ffff810feb5090b0 x26: ffff000017e57000 [ 341.547515] x25: 0000000000000000 x24: 00000000fbd00000 [ 341.552816] x23: 0000000000000000 x22: ffff810feb5090b0 [ 341.558117] x21: 0000000000000000 x20: 0000000000000000 [ 341.563418] x19: ffff000017e57000 x18: 0000000000000000 [ 341.568719] x17: 0000000000000000 x16: 0000000000000000 [ 341.574020] x15: 0000000000000010 x14: ffffffffffffffff [ 341.579321] x13: ffff00008985eb27 x12: ffff00000985eb2f [ 341.584622] x11: ffff0000096b3000 x10: ffff00001c5db510 [ 341.589923] x9 : 00000000ffffffd0 x8 : ffff0000086868e8 [ 341.595224] x7 : 3430303030303030 x6 : 00000000000006ef [ 341.600525] x5 : 00000000003fffff x4 : 0000000000000000 [ 341.605825] x3 : 0000000000000000 x2 : ffffffffffffffff [ 341.611126] x1 : ffff0000096b3728 x0 : 0000000000000038 [ 341.616428] Call trace: [ 341.618866] __vunmap+0x98/0xe0 [ 341.621997] vunmap+0x3c/0x50 [ 341.624961] arch_dma_free+0x68/0xa0 [ 341.628534] dma_direct_free+0x50/0x80 [ 341.632285] nicvf_free_resources+0x160/0x2d8 [nicvf] [ 341.637327] nicvf_config_data_transfer+0x174/0x5e8 [nicvf] [ 341.642890] nicvf_stop+0x298/0x340 [nicvf] [ 341.647066] __dev_close_many+0x9c/0x108 [ 341.650977] dev_close_many+0xa4/0x158 [ 341.654720] rollback_registered_many+0x140/0x530 [ 341.659414] rollback_registered+0x54/0x80 [ 341.663499] unregister_netdevice_queue+0x9c/0xe8 [ 341.668192] unregister_netdev+0x28/0x38 [ 341.672106] nicvf_remove+0xa4/0xa8 [nicvf] [ 341.676280] nicvf_shutdown+0x20/0x30 [nicvf] [ 341.680630] pci_device_shutdown+0x44/0x88 [ 341.684720] device_shutdown+0x144/0x250 [ 341.688640] kernel_restart_prepare+0x44/0x50 [ 341.692986] kernel_restart+0x20/0x68 [ 341.696638] __se_sys_reboot+0x210/0x238 [ 341.700550] __arm64_sys_reboot+0x24/0x30 [ 341.704555] el0_svc_handler+0x94/0x110 [ 341.708382] el0_svc+0x8/0xc [ 341.711252] ---[ end trace 3f4019c8439959c9 ]--- [ 341.715874] page:ffff7e0003ef4000 count:0 mapcount:0 mapping:0000000000000000 index:0x4 [ 341.723872] flags: 0x1fffe000000000() [ 341.727527] raw: 001fffe000000000 ffff7e0003f1a008 ffff7e0003ef4048 0000000000000000 [ 341.735263] raw: 0000000000000004 0000000000000000 00000000ffffffff 0000000000000000 [ 341.742994] page dumped because: VM_BUG_ON_PAGE(page_ref_count(page) == 0) where xdp_dummy.c is a simple bpf program that forwards the incoming frames to the network stack (available here: https://github.com/altoor/xdp_walkthrough_examples/blob/master/sample_1/xdp_dummy.c) Fixes: 05c773f52b96 ("net: thunderx: Add basic XDP support") Fixes: 4863dea3fab0 ("net: Adding support for Cavium ThunderX network controller") Signed-off-by: Lorenzo Bianconi <lorenzo.bianconi@redhat.com> Signed-off-by: David S.

2018-11-23team: no need to do team_notify_peers or team_mcast_rejoin when disabling portHangbin Liu
team_notify_peers() will send ARP and NA to notify peers. team_mcast_rejoin() will send multicast join group message to notify peers. We should do this when enabling/changed to a new port. But it doesn't make sense to do it when a port is disabled. On the other hand, when we set mcast_rejoin_count to 2, and do a failover, team_port_disable() will increase mcast_rejoin.count_pending to 2 and then team_port_enable() will increase mcast_rejoin.count_pending to 4. We will send 4 mcast rejoin messages at latest, which will make user confused. The same with notify_peers.count. Fix it by deleting team_notify_peers() and team_mcast_rejoin() in team_port_disable().

2018-11-23virtio-net: disable guest csum during XDP setJason Wang
We don't disable VIRTIO_NET_F_GUEST_CSUM if XDP was set. This means we can receive partial csumed packets with metadata kept in the vnet_hdr. This may have several side effects: - It could be overridden by header adjustment, thus is might be not correct after XDP processing. - There's no way to pass such metadata information through XDP_REDIRECT to another driver. - XDP does not support checksum offload right now. So simply disable guest csum if possible in this the case of XDP.

2018-11-21net: faraday: ftmac100: remove netif_running(netdev) check before disabling ↵Vincent Chen
interrupts In the original ftmac100_interrupt(), the interrupts are only disabled when the condition "netif_running(netdev)" is true. However, this condition causes kerenl hang in the following case. When the user requests to disable the network device, kernel will clear the bit __LINK_STATE_START from the dev->state and then call the driver's ndo_stop function. Network device interrupts are not blocked during this process. If an interrupt occurs between clearing __LINK_STATE_START and stopping network device, kernel cannot disable the interrupts due to the condition "netif_running(netdev)" in the ISR. Hence, kernel will hang due to the continuous interruption of the network device. In order to solve the above problem, the interrupts of the network device should always be disabled in the ISR without being restricted by the condition "netif_running(netdev)".

The following ib_atomic_bw invocation over XRC reproduces the issue: ib_atomic_bw -d mlx5_1 --connection=XRC --atomic_type=FETCH_AND_ADD It is safe to remove such checks because the QP type was already checked in ib_modify_qp_is_ok(), which was previously called from mlx5_ib_modify_qp.

2018-11-21RDMA/core: Add GIDs while changing MAC addr only for registered ndevParav Pandit
Currently when MAC address is changed, regardless of the netdev reg_state, GID entries are removed and added to reflect the new MAC address and new default GID entries. When a bonding device is used and the underlying PCI device is removed several netdevice events are generated. Two events of the interest are CHANGEADDR and UNREGISTER event on lower(slave) netdevice of the bond netdevice. Sometimes CHANGEADDR event is generated when netdev state is UNREGISTERING (after UNREGISTER event is generated). In this scenario, GID entries for default GIDs are added and never deleted because GID entries are deleted only when netdev state is < UNREGISTERED. This leads to non zero reference count on the netdevice. Due to this, PCI device unbind operation is getting stuck. To avoid it, when changing mac address, add GID entries only if netdev is in REGISTERED state.
