2017-02-20net: aquantia: remove function aq_ring_tx_deinitLino Sanfilippo3-39/+11
Both functions aq_ring_rx_deinit() and aq_ring_tx_clean() are almost identical aside from an additional check in the latter. Move that check from the function into its caller and replace aq_ring_rx_deinit() with aq_ring_rx_deinit(). By doing this also adjust the functions return value from int to void since it can never fail.

2017-02-20net: phy: Check phydev->drvFlorian Fainelli2-7/+25
There are number of function calls, originating from user-space, typically through the Ethernet driver that can make us crash by dereferencing phydev->drv which will be NULL once we unbind the driver from the PHY. There are still functional issues that prevent an unbind then rebind to work, but these will be addressed separately.

2017-02-20net: phy: Fix PHY unbind crashFlorian Fainelli1-0/+2
The PHY library does not deal very well with bind and unbind events. The first thing we would see is that we were not properly canceling the PHY state machine workqueue, so we would be crashing while dereferencing phydev->drv since there is no driver attached anymore.

2017-02-19ibmvnic: Make CRQ interrupt tasklet wait for all capabilities crqsThomas Falcon2-2/+15
After sending device capability queries and requests to the vNIC Server, an interrupt is triggered and the responses are written to the driver's CRQ response buffer. Since the interrupt can be triggered before all responses are written and visible to the partition, there is a danger that the interrupt handler or tasklet can terminate before all responses are read, resulting in a failure to initialize the device. To avoid this scenario, when capability commands are sent, we set a flag that will be checked in the following interrupt tasklet that will handle the capability responses from the server. Once all responses have been handled, the flag is disabled; and the tasklet is allowed to terminate. Signed-off-by: Thomas Falcon <[email protected]> Signed-off-by: David S.

2017-02-17vxlan: fix oops in dev_fill_metadata_dstPaolo Abeni1-2/+4
Since the commit 0c1d70af924b ("net: use dst_cache for vxlan device") vxlan_fill_metadata_dst() calls vxlan_get_route() passing a NULL dst_cache pointer, so the latter should explicitly check for valid dst_cache ptr. Unfortunately the commit d71785ffc7e7 ("net: add dst_cache to ovs vxlan lwtunnel") removed said check. As a result is possible to trigger a null pointer access calling vxlan_fill_metadata_dst(), e.g. with: ovs-vsctl add-br ovs-br0 ovs-vsctl add-port ovs-br0 vxlan0 -- set interface vxlan0 \ type=vxlan options:remote_ip=192.168.1.1 \ options:key=1234 options:dst_port=4789 ofport_request=10 ip address add dev ovs-br0 172.16.1.2/24 ovs-vsctl set Bridge ovs-br0 ipfix=@i -- --id=@i create IPFIX \ targets=\"172.16.1.1:1234\" sampling=1 iperf -c 172.16.1.1 -u -l 1000 -b 10M -t 1 -p 1234 This commit addresses the issue passing to vxlan_get_route() the dst_cache already available into the lwt info processed by vxlan_fill_metadata_dst().

efx_start_all can return without initialising queues as a reset is pending. This means that when netif_device_attach is called, the kernel can start sending traffic without having an initialised TX queue to send to.

2017-02-17sfc: fix filter_id misinterpretation in edge caseJon Cooper1-18/+30
On EF10, hardware filter IDs are 13 bits, but in some places we store 32-bit "full filter IDs" in which higher order bits encode the filter match-priority. This could cause a filter to have a full filter ID of 0xffff, which is also the value EFX_EF10_FILTER_ID_INVALID which we use in 16-bit "short" filter IDs (without match-priority bits). This would occur if the hardware filter ID was 0x1fff and the match-priority was 7. Unfortunately, some code that checks for EFX_EF10_FILTER_ID_INVALID can be called on full filter IDs, and will WARN_ON if this ever happens. So, since we have plenty of spare bits in the full filter ID, this patch shifts the priority bits left one bit when constructing the full filter IDs, ensuring that the 0x2000 bit of a full filter ID will always be 0 and thus no full filter ID can ever equal EFX_EF10_FILTER_ID_INVALID. This patch also replaces open-coded full<->short filter ID conversions with calls to functions, thus keeping the definition of the full filter ID format in one place.

I got a warning about broken code on ARM64 with 64K pages: drivers/net/vmxnet3/vmxnet3_drv.c: In function 'vmxnet3_rq_init': drivers/net/vmxnet3/vmxnet3_drv.c:1679:29: error: large integer implicitly truncated to unsigned type [-Werror=overflow] rq->buf_info[0][i].len = PAGE_SIZE; 'len' here is a 16-bit integer, so this clearly won't work. I don't think this driver is used much on anything other than x86, so there is no need to fix this properly and we can work around it with a Kconfig dependency to forbid known-broken configurations. qemu in theory supports it on other architectures too, but presumably only for compatibility with x86 guests that also run on vmware.

Tony updates the driver to advertise 2.5Gb and 5.0Gb if the adapter supports it. Stephen Hemminger renames our dcbnl_ops since it is global to ixgbe_dcbnl_ops to avoid namespace issues. Mark updates the driver version based on the recent changes. Alex has the remainder of the changes, starting with consolidating functions that represent logical steps in the receive process so we can later update them more easily (and align with igb). Modify the receive path to only synchronize the length of the frame versus the entire buffer. Provided performance improvements by adding support for DMA_ATTR_SKIP_CPU_SYNC and DMA_ATTR_WEAK_ORDERING. Also made additional performance gains by batching the page count updates instead of doing them one at a time. Adjusted the receive path to use 3k buffers with 8k backing them in order to support build_skb with jumbo frames. Made additional driver improvements by using the length of the packet instead of the DD status to determine if a new descriptor is ready to be processed, which cuts down on reads. To reduce code duplication, pulled apart the receive path into separate functions. Added support for providing a buffer with headroom and tailroom to allow for shared info for NET_SKB_PAD and NET_IP_ALIGN. ==================== Signed-off-by: David S. Miller <[email protected]>
