drivers: net: generalize napi_complete_done()

2017-01-30T20:10:42+00:00

napi_complete_done() allows to opt-in for gro_flush_timeout, added back in linux-3.19, commit 3b47d30396ba ("net: gro: add a per device gro flush timer") This allows for more efficient GRO aggregation without sacrifying latencies. Signed-off-by: Eric Dumazet Signed-off-by: David S. Miller

net: make ndo_get_stats64 a void function

2017-01-08T22:51:44+00:00

The network device operation for reading statistics is only called in one place, and it ignores the return value. Having a structure return value is potentially confusing because some future driver could incorrectly assume that the return value was used. Fix all drivers with ndo_get_stats64 to have a void function. Signed-off-by: Stephen Hemminger Signed-off-by: David S. Miller

Pull rdma updates from Doug Ledford: "This is the complete update for the rdma stack for this release cycle. Most of it is typical driver and core updates, but there is the entirely new VMWare pvrdma driver. You may have noticed that there were changes in DaveM's pull request to the bnxt Ethernet driver to support a RoCE RDMA driver. The bnxt_re driver was tentatively set to be pulled in this release cycle, but it simply wasn't ready in time and was dropped (a few review comments still to address, and some multi-arch build issues like prefetch() not working across all arches). Summary: - shared mlx5 updates with net stack (will drop out on merge if Dave's tree has already been merged) - driver updates: cxgb4, hfi1, hns-roce, i40iw, mlx4, mlx5, qedr, rxe - debug cleanups - new connection rejection helpers - SRP updates - various misc fixes - new paravirt driver from vmware" * tag 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dledford/rdma: (210 commits) IB: Add vmw_pvrdma driver IB/mlx4: fix improper return value IB/ocrdma: fix bad initialization infiniband: nes: return value of skb_linearize should be handled MAINTAINERS: Update Intel RDMA RNIC driver maintainers MAINTAINERS: Remove Mitesh Ahuja from emulex maintainers IB/core: fix unmap_sg argument qede: fix general protection fault may occur on probe IB/mthca: Replace pci_pool_alloc by pci_pool_zalloc mlx5, calc_sq_size(): Make a debug message more informative mlx5: Remove a set-but-not-used variable mlx5: Use { } instead of { 0 } to init struct IB/srp: Make writing the add_target sysfs attr interruptible IB/srp: Make mapping failures easier to debug IB/srp: Make login failures easier to debug IB/srp: Introduce a local variable in srp_add_one() IB/srp: Fix CONFIG_DYNAMIC_DEBUG=n build IB/multicast: Check ib_find_pkey() return value IPoIB: Avoid reading an uninitialized member variable IB/mad: Fix an array index check ...

vmxnet3: avoid assumption about invalid dma_pa in vmxnet3_set_mc()

2016-10-15T21:47:32+00:00

vmxnet3_set_mc() checks new_table_pa returned by dma_map_single() with dma_mapping_error(), but even there it assumes zero is invalid pa (it assumes dma_mapping_error(...,0) returns true if new_table is NULL). The patch adds an explicit variable to track status of new_table_pa. Found by Linux Driver Verification project (linuxtesting.org). v2: use "bool" and "true"/"false" for boolean variables.

vmxnet3: Wake queue from reset work

2016-10-04T04:36:13+00:00

vmxnet3_reset_work() expects tx queues to be stopped (via vmxnet3_quiesce_dev -> netif_tx_disable). However, this races with the netif_wake_queue() call in netif_tx_timeout() such that the driver's start_xmit routine may be called unexpectedly, triggering one of the BUG_ON in vmxnet3_map_pkt with a stack trace like this: RIP: 0010:[] vmxnet3_map_pkt+0x3ac/0x4c0 [vmxnet3] [] vmxnet3_tq_xmit+0x210/0x4e0 [vmxnet3] [] dev_hard_start_xmit+0x2e4/0x4c0 [] sch_direct_xmit+0x17e/0x1e0 [] __qdisc_run+0xd7/0x130 [] net_tx_action+0x10a/0x200 [] __do_softirq+0x11f/0x260 [] call_softirq+0x1c/0x30 [] do_softirq+0x65/0xa0 [] local_bh_enable_ip+0x99/0xa0 [] destroy_conntrack+0x96/0x110 [nf_conntrack] [] nf_conntrack_destroy+0x12/0x20 [] skb_release_head_state+0xb5/0xf0 [] skb_release_all+0x9/0x20 [] __kfree_skb+0x9/0x90 [] vmxnet3_quiesce_dev+0x209/0x340 [vmxnet3] [] vmxnet3_reset_work+0x6a/0xa0 [vmxnet3] [] process_one_work+0x16c/0x350 [] worker_thread+0x17a/0x410 [] kthread+0x96/0xa0 [] kernel_thread_helper+0x4/0x10 Signed-off-by: Benjamin Poirier Signed-off-by: David S.
