2019-10-01xen-netfront: do not use ~0U as error return value for xennet_fill_frags()Dongli Zhang1-8/+9
xennet_fill_frags() uses ~0U as return value when the sk_buff is not able to cache extra fragments. This is incorrect because the return type of xennet_fill_frags() is RING_IDX and 0xffffffff is an expected value for ring buffer index. In the situation when the rsp_cons is approaching 0xffffffff, the return value of xennet_fill_frags() may become 0xffffffff which xennet_poll() (the caller) would regard as error. As a result, queue->rx.rsp_cons is set incorrectly because it is updated only when there is error. If there is no error, xennet_poll() would be responsible to update queue->rx.rsp_cons. Finally, queue->rx.rsp_cons would point to the rx ring buffer entries whose queue->rx_skbs[i] and queue->grant_rx_ref[i] are already cleared to NULL. This leads to NULL pointer access in the next iteration to process rx ring buffer entries. The symptom is similar to the one fixed in commit 00b368502d18 ("xen-netfront: do not assume sk_buff_head list is empty in error handling"). This patch changes the return type of xennet_fill_frags() to indicate whether it is successful or failed. The queue->rx.rsp_cons will be always updated inside this function.

2019-10-01netfilter: drop bridge nf reset from nf_resetFlorian Westphal5-10/+10
commit 174e23810cd31 ("sk_buff: drop all skb extensions on free and skb scrubbing") made napi recycle always drop skb extensions. The additional skb_ext_del() that is performed via nf_reset on napi skb recycle is not needed anymore. Most nf_reset() calls in the stack are there so queued skb won't block 'rmmod nf_conntrack' indefinitely. This removes the skb_ext_del from nf_reset, and renames it to a more fitting nf_reset_ct(). In a few selected places, add a call to skb_ext_reset to make sure that no active extensions remain. I am submitting this for "net", because we're still early in the release cycle. The patch applies to net-next too, but I think the rename causes needless divergence between those trees.

But the PTP clock readout needs to happen quickly enough (in 0.135 seconds, in fact), otherwise the PTP clock will wrap around 24 bits, condition which cannot be detected. Looking at the 'max 134217731' value on output line 3, one can see that in hex it is 0x8000003. Because the PTP clock resolution is 8 ns, that means 0x1000000 in ticks, which is exactly 2^24. So indeed this is a PTP clock wraparound, but the reason might be surprising. What is going on is that sja1105_tstamp_reconstruct(priv, now, ts) expects a "now" time that is later than the "ts" was snapshotted at. This, of course, is obvious: we read the PTP time _after_ the partial RX timestamp was received. However, the workqueue is processing frames from a skb queue and reuses the same PTP time, read once at the beginning. Normally the skb queue only contains one frame and all goes well. But when the skb queue contains two frames, the second frame that gets dequeued might have been partially timestamped by the RX MAC _after_ we had read our PTP time initially. The code was originally like that due to concerns that SPI access for PTP time readout is a slow process, and we are time-constrained anyway (aka: premature optimization). But some timing analysis reveals that the time spent until the RX timestamp is completely reconstructed is 1 order of magnitude lower than the 0.135 s deadline even under worst-case conditions. So we can afford to read the PTP time for each frame in the RX timestamping queue, which of course ensures that the full PTP time is in the partial timestamp's future.

2019-09-27mlxsw: spectrum: Clear VLAN filters during port initializationIdo Schimmel1-0/+9
When a port is created, its VLAN filters are not cleared by the firmware. This causes tagged packets to be later dropped by the ingress STP filters, which default to DISCARD state. The above did not matter much until commit b5ce611fd96e ("mlxsw: spectrum: Add devlink-trap support") where we exposed the drop reason to users. Without this patch, the drop reason users will see is not consistent. If a port is enslaved to a VLAN-aware bridge and a packet with an invalid VLAN tries to ingress the bridge, it will be dropped due to ingress STP filter. If the VLAN is later enabled and then disabled, the packet will be dropped by the ingress VLAN filter despite the above being a seemingly NOP operation. Fix this by clearing all the VLAN filters during port initialization. Adjust the test accordingly.

The regmap stride is set to 1 for regmap describing 8bit registers already. However, for 16/32/64bit registers, the stride is 2/4/8 respectively. This is not correct, as the switch protocol supports unaligned register reads and writes and the KSZ87xx even uses such unaligned register accesses to read e.g. MIB counter. This patch fixes MIB counter access on KSZ87xx. Signed-off-by: Marek Vasut <[email protected]> Cc: Andrew Lunn <[email protected]> Cc: David S.

2019-09-26net: stmmac: Fix page pool sizeThierry Reding1-1/+3
The size of individual pages in the page pool in given by an order. The order is the binary logarithm of the number of pages that make up one of the pages in the pool. However, the driver currently passes the number of pages rather than the order, so it ends up wasting quite a bit of memory. Fix this by taking the binary logarithm and passing that in the order field.
