When VIRTIO_NET_F_GUEST_UFO is negotiated, host could still send UFO packet that exceeds a single page which could not be handled correctly by XDP. So this patch forbids setting XDP when GUEST_UFO is supported. While at it, forbid XDP for ECN (which comes only from GRO) too to prevent user from misconfiguration.

We don't update ewma rx buf size in the case of XDP. This will lead underestimation of rx buf size which causes host to produce more than one buffers. This will greatly increase the possibility of XDP page linearization.

When XDP_PASS were determined for linearized packets, we try to get new buffers in the virtqueue and build skbs from them. This is wrong, we should create skbs based on existed buffers instead. Fixing them by creating skb based on xdp_page. With this patch "ping 192.168.100.4 -s 3900 -M do" works for XDP_PASS.

We don't put page during linearizing, the would cause leaking when xmit through XDP_TX or the packet exceeds PAGE_SIZE. Fix them by put page accordingly. Also decrease the number of buffers during linearizing to make sure caller can free buffers correctly when packet exceeds PAGE_SIZE. With this patch, we won't get OOM after linearize huge number of packets.

Since we use EWMA to estimate the size of rx buffer. When rx buffer size is underestimated, it's usual to have a packet with more than one buffers.

At the end of the nexthop initialization process we determine whether the nexthop should be offloaded or not based on the NUD state of the neighbour representing it. After all the nexthops were initialized we refresh the nexthop group and potentially offload it to the device, in case some of the nexthops were resolved. Make the destruction of a nexthop group symmetric with its creation by marking all nexthops as invalid and then refresh the nexthop group to make sure it was removed from the device's tables.

Since commit 71ce391d ("net: mvpp2: enable proper per-CPU TX buffers unmapping"), we are not correctly DMA unmapping TX buffers for fragments. Indeed, the mvpp2_txq_inc_put() function only stores in the txq_cpu->tx_buffs[] array the physical address of the buffer to be DMA-unmapped when skb != NULL. In addition, when DMA-unmapping, we use skb_headlen(skb) to get the size to be unmapped. Both of this works fine for TX descriptors that are associated directly to a SKB, but not the ones that are used for fragments, with a NULL pointer as skb: - We have a NULL physical address when calling DMA unmap - skb_headlen(skb) crashes because skb is NULL This causes random crashes when fragments are used. To solve this problem, we need to: - Store the physical address of the buffer to be unmapped unconditionally, regardless of whether it is tied to a SKB or not. - Store the length of the buffer to be unmapped, which requires a new field. Instead of adding a third array to store the length of the buffer to be unmapped, and as suggested by David Miller, this commit refactors the tx_buffs[] and tx_skb[] arrays of 'struct mvpp2_txq_pcpu' into a separate structure 'mvpp2_txq_pcpu_buf', to which a 'size' field is added. Therefore, instead of having three arrays to allocate/free, we have a single one, which also improve data locality, reducing the impact on the CPU cache.

Right now the dwmac-rk tries to set up the GRF-specific speed and link options before enabling clocks, phys etc and on previous socs this works because the GRF is supplied on the whole by one clock. On the rk3399 however the GRF (General Register Files) clock-supply has been split into multiple clocks and while there is no specific grf-gmac clock like for other sub-blocks, it seems the mac-specific portions are actually supplied by the general mac clock. This results in hangs on rk3399 boards if the driver is build as module. When built in te problem of course doesn't surface, as the clocks are of course still on at the stage before clock_disable_unused. To solve this, simply move the clock enablement to the first position in the powerup callback. This is also a good idea in general to enable clocks before everything else. Tested on rk3288, rk3368 and rk3399 the dwmac still works on all of them. Signed-off-by: NHeiko Stuebner <heiko@sntech.de> Signed-off-by: NDavid S. Miller <davem@davemloft.net>

With commit e4965614 {"rtlwifi: Use dev_kfree_skb_irq instead of kfree_skb"), the method used to free an skb was changed because the kfree_skb() was inside a spinlock. What was forgotten is that kfree_skb() guards against a NULL value for the argument. Routine dev_kfree_skb_irq() does not, and a test is needed to prevent kernel panics.

The patches regarding eee-broken-modes was merged before all people involved could find an agreement on the best way to move forward. While we agreed on having a DT property to mark particular modes as broken, the value used for eee-broken-modes mapped the phy register in very direct way. Because of this, the concern is that it could be used to implement configuration policies instead of describing a broken HW. In the end, having a boolean property for each mode seems to be preferred over one bit field value mapping the register (too) directly.
