The vsc85xx_default_config function called in the vsc85xx_config_init function which is used by VSC8530, VSC8531, VSC8540 and VSC8541 PHYs mistakenly calls phy_read and phy_write in-between phy_select_page and phy_restore_page. phy_select_page and phy_restore_page actually take and release the MDIO bus lock and phy_write and phy_read take and release the lock to write or read to a PHY register. Let's fix this deadlock by using phy_modify_paged which handles correctly a read followed by a write in a non-standard page.

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().

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.

Eric noted that with UDP GRO and NAPI timeout, we could keep a single UDP packet inside the GRO hash forever, if the related NAPI instance calls napi_gro_complete() at an higher frequency than the NAPI timeout. Willem noted that even TCP packets could be trapped there, till the next retransmission. This patch tries to address the issue, flushing the old packets - those with a NAPI_GRO_CB age before the current jiffy - before scheduling the NAPI timeout. The rationale is that such a timeout should be well below a jiffy and we are not flushing packets eligible for sane GRO. v1 -> v2: - clarified the commit message and comment RFC -> v1: - added 'Fixes tags', cleaned-up the wording.

When we add a new IPv6 address, we should also join corresponding solicited-node multicast address, unless the interface has IFF_NOARP flag, as function addrconf_join_solict() did. But if we remove IFF_NOARP flag later, we do not do dad and add the mcast address. So we will drop corresponding neighbour discovery message that came from other nodes. A typical example is after creating a ipvlan with mode l3, setting up an ipv6 address and changing the mode to l2. Then we will not be able to ping this address as the interface doesn't join related solicited-node mcast address. Fix it by re-doing dad when interface changed IFF_NOARP flag. Then we will add corresponding mcast group and check if there is a duplicate address on the network.

tpacket_snd sends packets with user pages linked into skb frags. It notifies that pages can be reused when the skb is released by setting skb->destructor to tpacket_destruct_skb. This can cause data corruption if the skb is orphaned (e.g., on transmit through veth) or cloned (e.g., on mirror to another psock). Create a kernel-private copy of data in these cases, same as tun/tap zerocopy transmission. Reuse that infrastructure: mark the skb as SKBTX_ZEROCOPY_FRAG, which will trigger copy in skb_orphan_frags(_rx). Unlike other zerocopy packets, do not set shinfo destructor_arg to struct ubuf_info. tpacket_destruct_skb already uses that ptr to notify when the original skb is released and a timestamp is recorded. Do not change this timestamp behavior. The ubuf_info->callback is not needed anyway, as no zerocopy notification is expected. Mark destructor_arg as not-a-uarg by setting the lower bit to 1. The resulting value is not a valid ubuf_info pointer, nor a valid tpacket_snd frame address. Add skb_zcopy_.._nouarg helpers for this. The fix relies on features introduced in commit 52267790 ("sock: add MSG_ZEROCOPY"), so can be backported as is only to 4.14.

Thomas Falcon says: ==================== ibmvnic: Fix queue and buffer accounting errors This series includes two small fixes. The first resolves a typo bug in the code to clean up unused RX buffers during device queue removal. The second ensures that device queue memory is updated to reflect new supported queue ring sizes after migration to other backing hardware. ==================== Signed-off-by: NDavid S.

On every iteration of net_dim, the algorithm may choose to check for the system state by comparing current data sample with previous data sample. After each of these comparison, regardless of the action taken, the sample used as baseline is needed to be updated. This patch fixes a bug that causes DIM to take wrong decisions, due to never updating the baseline sample for comparison between iterations. This way, DIM always compares current sample with zeros. Although this is a functional fix, it also improves and stabilizes performance as the algorithm works properly now. Performance: Tested single UDP TX stream with pktgen: samples/pktgen/pktgen_sample03_burst_single_flow.sh -i p4p2 -d 1.1.1.1 -m 24:8a:07:88:26:8b -f 3 -b 128 ConnectX-5 100GbE packet rate improved from 15-19Mpps to 19-20Mpps. Also, toggling between profiles is less frequent with the fix.

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)". [V2] Remove unnecessary curly braces. Signed-off-by: NVincent Chen <vincentc@andestech.com> Signed-off-by: NDavid S. Miller <davem@davemloft.net>
