Vhost-net has a hard limit on the number of zerocopy skbs in flight. When reached, transmission stalls. Stalls cause latency, as well as head-of-line blocking of other flows that do not use zerocopy. Instead of stalling, revert to copy-based transmission. Tested by sending two udp flows from guest to host, one with payload of VHOST_GOODCOPY_LEN, the other too small for zerocopy (1B). The large flow is redirected to a netem instance with 1MBps rate limit and deep 1000 entry queue. modprobe ifb ip link set dev ifb0 up tc qdisc add dev ifb0 root netem limit 1000 rate 1MBit tc qdisc add dev tap0 ingress tc filter add dev tap0 parent ffff: protocol ip \ u32 match ip dport 8000 0xffff \ action mirred egress redirect dev ifb0 Before the delay, both flows process around 80K pps. With the delay, before this patch, both process around 400. After this patch, the large flow is still rate limited, while the small reverts to its original rate. See also discussion in the first link, below. Without rate limiting, {1, 10, 100}x TCP_STREAM tests continued to send at 100% zerocopy. The limit in vhost_exceeds_maxpend must be carefully chosen. With vq->num >> 1, the flows remain correlated. This value happens to correspond to VHOST_MAX_PENDING for vq->num == 256. Allow smaller fractions and ensure correctness also for much smaller values of vq->num, by testing the min() of both explicitly. See also the discussion in the second link below.

Switch the DO_ONCE() macro from the deprecated jump label API to the new one. The new one is more readable, and for DO_ONCE() it also makes the generated code more icache-friendly: now the one-time initialization code is placed out-of-line at the jump target, rather than at the inline fallthrough case.

Jeff Kirsher says: ==================== 40GbE Intel Wired LAN Driver Updates 2017-10-09 This series contains updates to i40e and i40evf only. Jake fixes missed flag conversion from u64 to u32. Fixes a deafult ITR value issue where the driver defaults to an ITR value of half the expected value (in terms of minimum microseconds between interrupts). So fix this by changing the default values to be calculated using the ITR_REG_TO_USEC() macro which indicates that we are converting from the register units into microseconds. Updates the drivers to bump the tail in increments of 8 and double the number of descriptors we will bundle into one tail bump when receiving. With the recent kernel support for enabling XPS and QoS at the same time, we no longer need to worry about the number of traffic classes when enabling XPS. Lihong converts the use of hash_for_each() to hash_for_each_safe() to safely remove a hash entry. Adds a check for the return value for find_first_bit() in the case that it returns the size passed to search. Alan fixes a bug in which filters are erroneously removed if they are removed and then added again. So make sure that when adding a filter, if we find it already existed in our list, make sure it is not marked to be removed. Jayaprakash adds the retrying of PHY reads when the I2C is busy for a maximum period of 500ms. Rami fixes code comment typo. Stefano Brivio simplifies the code by removing the use of a local return code variable and simply return the results of the read function. ==================== Signed-off-by:

Jeff Kirsher says: ==================== 10GbE Intel Wired LAN Driver Updates 2017-10-09 This series contains updates to ixgbe only. Emil fixes an issue where the semaphore bits could be stuck after a reset or a crash, by adding the clearing of software resource bits in the software/firmware synchronization register. Added error checks when we attempt to identify and initialize the PHY to prevent a crash. Fixed a few issues in the logic of ixgbe_clean_test_rings() which was exposed by a previous commit that was causing a crash in ethtool diagnostics. Bhumika Goyal fixes a couple of instances which were overlooked when we made ixgbe_mac_operations constant. Shannon Nelson fixes an issue to restore normal operations after the last MACVLAN offload is removed, otherwise we get stuck in a single queue operations. The infamous Jesper Dangaard Brouer adds a counter which counts the number of times the recycle fails and the real page allocator is invoked. Alex updates the adaptive ITR algorithm to better support the needs of the network. This attempt to make it so that our ITR algorithm will try to prevent either starving a socket buffer for memory in the case of transmit, or overrunning an receive socket buffer on receive. We should function better with new features like XDP which can handle small packets at high rates without needing to lock us into NAPI polling mode. ==================== Signed-off-by: -

The u-blox TOBY-L2 is a LTE Cat 4 module with HSPA+ and 2G fallback. This module allows switching to different USB profiles with the 'AT+UUSBCONF' command, and provides a ECM network interface when the 'AT+UUSBCONF=2' profile is selected. The u-blox SARA-U2 is a HSPA module with 2G fallback. The default USB configuration includes a ECM network interface. Both these modules are controlled via AT commands through one of the TTYs exposed. Connecting these modules may be done just by activating the desired PDP context with 'AT+CGACT=1,<cid>' and then running DHCP on the ECM interface. Signed-off-by:

Double the number of descriptors we'll bundle into one tail bump when receiving. Empirical testing has shown that we reduce CPU utilization and don't appear to reduce throughput or packet rate. 32 seems to be the sweet spot, as it's half the default polling budget, so we'd essentially reduce from 4 tail writes when polling down to 2. Increasing this up to 64 appears to have negative impacts as it may become possible that we don't bump the tail each time we get polled, which could cause a long delay between returning descriptors to the hardware.

Hardware only fetches descriptors on cachelines of 8, essentially ignoring the lower 3 bits of the tail register. Thus, it is pointless to bump tail by an unaligned access as the hardware will ignore some of the new descriptors we allocated. Thus, it's ideal if we can ensure tail writes are always aligned to 8. At first, it seems like we'd already do this, since we allocate descriptors in batches which are a multiple of 8. Since we'd always increment by a multiple of 8, it seems like the value should always be aligned. However, this ignores allocation failures. If we fail to allocate a buffer, our tail register will become unaligned. Once it has become unaligned it will essentially be stuck unaligned until a buffer allocation happens to fail at the exact amount necessary to re-align it. We can do better, by simply rounding down the number of buffers we're about to allocate (cleaned_count) such that "next_to_clean + cleaned_count" is rounded to the nearest multiple of 8. We do this by calculating how far off that value is and subtracting it from the cleaned_count. This essentially defers allocation of buffers if they're going to be ignored by hardware anyways, and re-aligns our next_to_use and tail values after a failure to allocate a descriptor. This calculation ensures that we always align the tail writes in a way the hardware expects and don't unnecessarily allocate buffers which won't be fetched immediately. Signed-off-by:

The lrxq thresh value tells hardware to immediately interrupt when there are fewer than N*64 packets left in the ring. Counter intuitively, empirical testing has shown that decreasing this value from 2 to 1, and thus changing from an immediate interrupt at fewer than 128 descriptors down to 64 descriptors causes a small increase in the maximum total packets per second we can receive. This increase occurs even when we're polling with interrupts masked, as the hardware must still handle interrupts internally even if we've disabled them in software. Also reduce the value for any VFs we allocate. Signed-off-by:

In the past we changed driver behavior to not clear the PBA when re-enabling interrupts. This change was motivated by the flawed belief that clearing the PBA would cause a lost interrupt if a receive interrupt occurred while interrupts were disabled. According to empirical testing this isn't the case. Additionally, the data sheet specifically says that we should set the CLEARPBA bit when re-enabling interrupts in a polling setup. This reverts commit 40d72a50 ("i40e/i40evf: don't lose interrupts") Signed-off-by:

The ITR register expects to be programmed in units of 2 microseconds. Because of this, all of the drivers I40E_ITR_* constants are in terms of this 2 microsecond register. Unfortunately, the rx_itr_default value is expected to be programmed in microseconds. Effectively the driver defaults to an ITR value of half the expected value (in terms of minimum microseconds between interrupts). Fix this by changing the default values to be calculated using ITR_REG_TO_USEC macro which indicates that we're converting from the register units into microseconds. Signed-off-by:

Due to the asynchronous nature in which mac filters are added and deleted, there exists a bug in which filters are erroneously removed if removed then added again quickly. The events are as such: - filter marked for removal - same filter is re-added before watchdog that cleans up filters - we skip re-adding the filter because we have it already in the list - watchdog filter cleanup kicks off and filter is removed So when we were re-adding the same filter, it didn't actually get added because it already existed in the list, but was marked for removal and had yet to actually be removed. This patch fixes the issue by making sure that when adding a filter, if we find it already existing in our list, make sure it is not marked to be removed.
