| 2021-12-08 | vmxnet3: fix minimum vectors alloc issue |   Ronak Doshi | 1 | -6/+7 | |
| 'Commit 39f9895a00f4 ("vmxnet3: add support for 32 Tx/Rx queues")' added support for 32Tx/Rx queues. Within that patch, value of VMXNET3_LINUX_MIN_MSIX_VECT was updated. However, there is a case (numvcpus = 2) which actually requires 3 intrs which matches VMXNET3_LINUX_MIN_MSIX_VECT which then is treated as failure by stack to allocate more vectors. This patch fixes this issue.

| 2021-11-01 | net: vmxnet3: remove multiple false checks in vmxnet3_ethtool.c |   Jean Sacren | 1 | -8/+2 | |
| In one if branch, (ec->rx_coalesce_usecs != 0) is checked. When it is checked again in two more places, it is always false and has no effect on the whole check expression. We should remove it in both places. In another if branch, (ec->use_adaptive_rx_coalesce != 0) is checked. When it is checked again, it is always false. We should remove the entire branch with it. In addition we might as well let C precedence dictate by getting rid of two pairs of parentheses in the neighboring lines in order to keep expressions on both sides of '||' in balance with checkpatch warning silenced.

| 2021-08-23 | vmxnet3: switch from 'pci_' to 'dma_' API |   Christophe JAILLET | 1 | -27/+20 | |
| The wrappers in include/linux/pci-dma-compat.h should go away. The patch has been generated with the coccinelle script below. It has been hand modified to use 'dma_set_mask_and_coherent()' instead of 'pci_set_dma_mask()/pci_set_consistent_dma_mask()' when applicable. This is less verbose. The explicit 'err = -EIO;' has been removed because 'dma_set_mask_and_coherent()' returns 0 or -EIO, so its return code can be used directly. It has been compile tested. @@ @@ - PCI_DMA_BIDIRECTIONAL + DMA_BIDIRECTIONAL @@ @@ - PCI_DMA_TODEVICE + DMA_TO_DEVICE @@ @@ - PCI_DMA_FROMDEVICE + DMA_FROM_DEVICE @@ @@ - PCI_DMA_NONE + DMA_NONE @@ expression e1, e2, e3; @@ - pci_alloc_consistent(e1, e2, e3) + dma_alloc_coherent(&e1->dev, e2, e3, GFP_) @@ expression e1, e2, e3; @@ - pci_zalloc_consistent(e1, e2, e3) + dma_alloc_coherent(&e1->dev, e2, e3, GFP_) @@ expression e1, e2, e3, e4; @@ - pci_free_consistent(e1, e2, e3, e4) + dma_free_coherent(&e1->dev, e2, e3, e4) @@ expression e1, e2, e3, e4; @@ - pci_map_single(e1, e2, e3, e4) + dma_map_single(&e1->dev, e2, e3, e4) @@ expression e1, e2, e3, e4; @@ - pci_unmap_single(e1, e2, e3, e4) + dma_unmap_single(&e1->dev, e2, e3, e4) @@ expression e1, e2, e3, e4, e5; @@ - pci_map_page(e1, e2, e3, e4, e5) + dma_map_page(&e1->dev, e2, e3, e4, e5) @@ expression e1, e2, e3, e4; @@ - pci_unmap_page(e1, e2, e3, e4) + dma_unmap_page(&e1->dev, e2, e3, e4) @@ expression e1, e2, e3, e4; @@ - pci_map_sg(e1, e2, e3, e4) + dma_map_sg(&e1->dev, e2, e3, e4) @@ expression e1, e2, e3, e4; @@ - pci_unmap_sg(e1, e2, e3, e4) + dma_unmap_sg(&e1->dev, e2, e3, e4) @@ expression e1, e2, e3, e4; @@ - pci_dma_sync_single_for_cpu(e1, e2, e3, e4) + dma_sync_single_for_cpu(&e1->dev, e2, e3, e4) @@ expression e1, e2, e3, e4; @@ - pci_dma_sync_single_for_device(e1, e2, e3, e4) + dma_sync_single_for_device(&e1->dev, e2, e3, e4) @@ expression e1, e2, e3, e4; @@ - pci_dma_sync_sg_for_cpu(e1, e2, e3, e4) + dma_sync_sg_for_cpu(&e1->dev, e2, e3, e4) @@ expression e1, e2, e3, e4; @@ - pci_dma_sync_sg_for_device(e1, e2, e3, e4) + dma_sync_sg_for_device(&e1->dev, e2, e3, e4) @@ expression e1, e2; @@ - pci_dma_mapping_error(e1, e2) + dma_mapping_error(&e1->dev, e2) @@ expression e1, e2; @@ - pci_set_dma_mask(e1, e2) + dma_set_mask(&e1->dev, e2) @@ expression e1, e2; @@ - pci_set_consistent_dma_mask(e1, e2) + dma_set_coherent_mask(&e1->dev, e2) Signed-off-by: Christophe JAILLET <christophe.jaillet@wanadoo.fr> Signed-off-by: David S.

| So this patch actually does 3 things. First it removes a stray white space at the start of the variable declaration in vmxnet3_get_strings. Second it flips the logic for the string test so that we exit immediately if we are not looking for the stats strings. Doing this we can avoid unnecessary indentation and line wrapping. Then finally it updates the code to use ethtool_sprintf rather than a memcpy and pointer increment to write the ethtool strings.

| 2021-01-29 | vmxnet3: Remove buf_info from device accessible structures | Ronak Doshi | 2 | -33/+15 | |
| buf_info structures in RX & TX queues are private driver data that do not need to be visible to the device. Although there is physical address and length in the queue descriptor that points to these structures, their layout is not standardized, and device never looks at them. So lets allocate these structures in non-DMA-able memory, and fill physical address as all-ones and length as zero in the queue descriptor. That should alleviate worries brought by Martin Radev in https://lists.osuosl.org/pipermail/intel-wired-lan/Week-of-Mon-20210104/022829.html that malicious vmxnet3 device could subvert SVM/TDX guarantees.

| Vmxnet3 version 3 device supports checksum/TSO offload. Thus, vNIC to pNIC traffic can leverage hardware checksum/TSO offloads. However, vmxnet3 does not support checksum/TSO offload for Geneve/VXLAN encapsulated packets. Thus, for a vNIC configured with an overlay, the guest stack must first segment the inner packet, compute the inner checksum for each segment and encapsulate each segment before transmitting the packet via the vNIC. This results in significant performance penalty. This patch will enhance vmxnet3 to support Geneve/VXLAN TSO as well as checksum offload.

| S390 bpf_jit.S is removed in net-next and had changes in 'net', since that code isn't used any more take the removal. TLS data structures split the TX and RX components in 'net-next', put the new struct members from the bug fix in 'net' into the RX part. The 'net-next' tree had some reworking of how the ERSPAN code works in the GRE tunneling code, overlapping with a one-line headroom calculation fix in 'net'. Overlapping changes in __sock_map_ctx_update_elem(), keep the bits that read the prog members via READ_ONCE() into local variables before using them. Signed-off-by: David S.

| 2018-04-19 | vmxnet3: fix incorrect dereference when rxvlan is disabled | Ronak Doshi | 2 | -6/+15 | |
| vmxnet3_get_hdr_len() is used to calculate the header length which in turn is used to calculate the gso_size for skb. When rxvlan offload is disabled, vlan tag is present in the header and the function references ip header from sizeof(ethhdr) and leads to incorrect pointer reference. This patch fixes this issue by taking sizeof(vlan_ethhdr) into account if vlan tag is present and correctly references the ip hdr.

| 2018-03-17 | vmxnet3: use correct flag to indicate LRO feature | Ronak Doshi | 2 | -4/+4 | |
| 'Commit 45dac1d6ea04 ("vmxnet3: Changes for vmxnet3 adapter version 2 (fwd)")' introduced a flag "lro" in structure vmxnet3_adapter which is used to indicate whether LRO is enabled or not. However, the patch did not set the flag and hence it was never exercised. So, when LRO is enabled, it resulted in poor TCP performance due to delayed acks. This issue is seen with packets which are larger than the mss getting a delayed ack rather than an immediate ack, thus resulting in high latency. This patch removes the lro flag and directly uses device features against NETIF_F_LRO to check if lro is enabled.

| 2018-03-17 | vmxnet3: avoid xmit reset due to a race in vmxnet3 | Ronak Doshi | 2 | -7/+10 | |
| The field txNumDeferred is used by the driver to keep track of the number of packets it has pushed to the emulation. The driver increments it on pushing the packet to the emulation and the emulation resets it to 0 at the end of the transmit. There is a possibility of a race either when (a) ESX is under heavy load or (b) workload inside VM is of low packet rate. This race results in xmit hangs when network coalescing is disabled. This change creates a local copy of txNumDeferred and uses it to perform ring arithmetic.

| 2018-01-23 | vmxnet3: repair memory leak |   Neil Horman | 1 | -1/+1 | |
| with the introduction of commit b0eb57cb97e7837ebb746404c2c58c6f536f23fa, it appears that rq->buf_info is improperly handled. While it is heap allocated when an rx queue is setup, and freed when torn down, an old line of code in vmxnet3_rq_destroy was not properly removed, leading to rq->buf_info[0] being set to NULL prior to its being freed, causing a memory leak, which eventually exhausts the system on repeated create/destroy operations (for example, when the mtu of a vmxnet3 interface is changed frequently. Fix is pretty straight forward, just move the NULL set to after the free.

| 2017-11-30 | vmxnet3: increase default rx ring sizes |   Shrikrishna Khare | 1 | -4/+4 | |
| There are several reasons for increasing the receive ring sizes: 1. The original ring size of 256 was chosen about 10 years ago when vmxnet3 was first created. At that time, 10Gbps Ethernet was not prevalent and servers were dominated by 1Gbps Ethernet. Now 10Gbps is common place, and higher bandwidth links -- 25Gbps, 40Gbps, 50Gbps -- are starting to appear. 256 Rx ring entries are simply not enough to keep up with higher link speed when there is a burst of network frames coming from these high speed links. Even with full MTU size frames, they are gone in a short time. It is also more common to have a mix of frame sizes, and more likely bi-modal distribution of frame sizes so the average frame size is not close to full MTU. If we consider average frame size of 800B, 1024 frames that come in a burst takes ~0.65 ms to arrive at 10Gbps. With 256 entires, it takes ~0.16 ms to arrive at 10Gbps. At 25Gbps or 40Gbps, this time is reduced accordingly. 2. On a hypervisor where there are many VMs and CPU is over committed, i.e. the number of VCPUs is more than the number of VCPUs, each PCPU is in effect time shared between multiple VMs/VCPUs. The time granularity at which this multiplexing occurs is typically coarser than between processes on a guest OS. Trying to time slice more finely is not efficient, for example, if memory cache is barely warmed up when switching from one VM to another occurs. This CPU overcommit adds delay to when the driver in a VM can service incoming packets. Whether CPU is over committed really depends on customer workloads. For certain situations, it is very common. For example, workloads of desktop VMs and product testing setups. Consolidation and sharing is what drives efficiency of a customer setup for such workloads. In these situations, the raw network bandwidth may not be very high, but the delays between when a VM is running or not running can also be relatively long.
