* smsc95xx: use ethtool_op_get_ts_info()Petr Kulhavy2017-07-141-0/+1
| | | | | | | | | | | | | | This change enables the use of SW timestamping on Raspberry PI. smsc95xx uses the usbnet transmit function usbnet_start_xmit(), which implements software timestamping. However the SOF_TIMESTAMPING_TX_SOFTWARE capability was missing and only SOF_TIMESTAMPING_RX_SOFTWARE was announced. By using ethtool_op_get_ts_info() as get_ts_info() also the SOF_TIMESTAMPING_TX_SOFTWARE is announced.

* cdc_ncm: Set NTB format again after altsetting switch for Huawei devicesEnrico Mioso2017-07-142-0/+34
| | | | | | | | | | | | | | | | | | | | | | | | | | Some firmwares in Huawei E3372H devices have been observed to switch back to NTB 32-bit format after altsetting switch. This patch implements a driver flag to check for the device settings and set NTB format to 16-bit again if needed. The flag has been activated for devices controlled by the huawei_cdc_ncm.c driver. V1->V2: - fixed broken error checks - some corrections to the commit message V2->V3: - variable name changes, to clarify what's happening - check (and possibly set) the NTB format later in the common bind code path Signed-off-by: Enrico Mioso <mrkiko.rs@gmail.com> Reported-and-tested-by: Christian Panton <christian@panton.org> Reviewed-by: Bjørn Mork <bjorn@mork.no> CC: Bjørn Mork <bjorn@mork.no> CC: Christian Panton <christian@panton.org> CC: linux-usb@vger.kernel.org CC: netdev@vger.kernel.org CC: Oliver Neukum <oliver@neukum.org> Signed-off-by: David S.

* net: cdc_ncm: Reduce memory use when kernel memory lowJim Baxter2017-07-031-12/+42
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The CDC-NCM driver can require large amounts of memory to create skb's and this can be a problem when the memory becomes fragmented. This especially affects embedded systems that have constrained resources but wish to maximise the throughput of CDC-NCM with 16KiB NTB's. The issue is after running for a while the kernel memory can become fragmented and it needs compacting. If the NTB allocation is needed before the memory has been compacted the atomic allocation can fail which can cause increased latency, large re-transmissions or disconnections depending upon the data being transmitted at the time. This situation occurs for less than a second until the kernel has compacted the memory but the failed devices can take a lot longer to recover from the failed TX packets. To ease this temporary situation I modified the CDC-NCM TX path to temporarily switch into a reduced memory mode which allocates an NTB that will fit into a USB_CDC_NCM_NTB_MIN_OUT_SIZE (default 2048 Bytes) sized memory block and only transmit NTB's with a single network frame until the memory situation is resolved. Each time this issue occurs we wait for an increasing number of reduced size allocations before requesting a full size one to not put additional pressure on a low memory system. Once the memory is compacted the CDC-NCM data can resume transmitting at the normal tx_max rate once again.

However, the release of these resources can occur in one of two different places. Either netdev_ops->ndo_uninit() or netdev->destructor(). The decision of which operation frees the resources depends upon whether it is necessary for all netdev refs to be released before it is safe to perform the freeing. netdev_ops->ndo_uninit() presumably can occur right after the NETDEV_UNREGISTER notifier completes and the unicast and multicast address lists are flushed. netdev->destructor(), on the other hand, does not run until the netdev references all go away. Further complicating the situation is that netdev->destructor() almost universally does also a free_netdev(). This creates a problem for the logic in register_netdevice(). Because all callers of register_netdevice() manage the freeing of the netdev, and invoke free_netdev(dev) if register_netdevice() fails. If netdev_ops->ndo_init() succeeds, but something else fails inside of register_netdevice(), it does call ndo_ops->ndo_uninit(). But it is not able to invoke netdev->destructor(). This is because netdev->destructor() will do a free_netdev() and then the caller of register_netdevice() will do the same. However, this means that the resources that would normally be released by netdev->destructor() will not be. Over the years drivers have added local hacks to deal with this, by invoking their destructor parts by hand when register_netdevice() fails. Many drivers do not try to deal with this, and instead we have leaks. Let's close this hole by formalizing the distinction between what private things need to be freed up by netdev->destructor() and whether the driver needs unregister_netdevice() to perform the free_netdev(). netdev->priv_destructor() performs all actions to free up the private resources that used to be freed by netdev->destructor(), except for free_netdev(). netdev->needs_free_netdev is a boolean that indicates whether free_netdev() should be done at the end of unregister_netdevice(). Now, register_netdevice() can sanely release all resources after ndo_ops->ndo_init() succeeds, by invoking both ndo_ops->ndo_uninit() and netdev->priv_destructor(). And at the end of unregister_netdevice(), we invoke netdev->priv_destructor() and optionally call free_netdev(). Signed-off-by: David S. Miller <davem@davemloft.net>

| | | | | | | | | | | | | | | | | | | | | | | | | | When TX checksum offload is used, if the computed checksum is 0 the LAN95xx device do not alter the checksum to 0xffff. In the case of ipv4 UDP checksum, it indicates to receiver that no checksum is calculated. Under ipv6, UDP checksum yields a result of zero must be changed to 0xffff. Hence disabling checksum offload for ipv6 packets. Signed-off-by: Nisar Sayed <Nisar.Sayed@microchip.com> Reported-by: popcorn mix <popcornmix@gmail.com> Signed-off-by: David S.

* net: cdc_ncm: Fix TX zero paddingJim Baxter2017-05-081-4/+7
| | | | | | | | | | | | | | | | | The zero padding that is added to NTB's does not zero the memory correctly. This is because the skb_put modifies the value of skb_out->len which results in the memset command not setting any memory to zero as (ctx->tx_max - skb_out->len) == 0. I have resolved this by storing the size of the memory to be zeroed before the skb_put and using this in the memset call.
