sunvnet: Invoke SET_NETDEV_DEV() to set up the vdev in vnet_new()

2015-09-21T23:28:36Z

`ls /sys/devices/channel-devices/vnet-port-0-0/net' is missing without this change, and applications like NetworkManager are looking in sysfs for the information. Signed-off-by: Sowmini Varadhan Signed-off-by: David S. Miller

sungem, sunhme, sunvnet: Update drivers to use dma_wmb/rmb

2015-04-08T16:15:14Z

This patch goes through and replaces wmb/rmb with dma_wmb/dma_rmb in cases where the barrier is being used to order writes or reads to just memory and doesn't involve any programmed I/O. Signed-off-by: Alexander Duyck Signed-off-by: David S. Miller

sunvnet: failed trigger should not cause BUG_ON()

2015-02-20T22:44:24Z

An error return from __vnet_tx_trigger() sets the TX descriptor to VIO_DESC_FREE while leaving port->tx_bufs[txi].skb set. This leads to a BUG_ON() the next time this descriptor is used. This patch frees the pending skb when getting a trigger error to match the VIO_DESC_FREE state. Signed-off-by: David L Stevens Acked-by: Sowmini Varadhan Signed-off-by: David S. Miller

sunvnet: don't change gso data on clones

2015-02-12T03:41:40Z

This patch unclones an skb for the case where the sunvnet driver needs to change the segmentation size so that it doesn't interfere with TCP SACK's use of them. Signed-off-by: David L Stevens Acked-by: Eric Dumazet Signed-off-by: David S. Miller

Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net

2015-02-05T22:33:28Z

Conflicts: drivers/net/vxlan.c drivers/vhost/net.c include/linux/if_vlan.h net/core/dev.c The net/core/dev.c conflict was the overlap of one commit marking an existing function static whilst another was adding a new function. In the include/linux/if_vlan.h case, the type used for a local variable was changed in 'net', whereas the function got rewritten to fix a stacked vlan bug in 'net-next'. In drivers/vhost/net.c, Al Viro's iov_iter conversions in 'net-next' overlapped with an endainness fix for VHOST 1.0 in 'net'. In drivers/net/vxlan.c, vxlan_find_vni() added a 'flags' parameter in 'net-next' whereas in 'net' there was a bug fix to pass in the correct network namespace pointer in calls to this function.

sunvnet: set queue mapping when doing packet copies

2015-02-03T02:20:35Z

This patch fixes a bug where vnet_skb_shape() didn't set the already-selected queue mapping when a packet copy was required. This results in using the wrong queue index for stops/starts, hung tx queues and watchdog timeouts under heavy load. Signed-off-by: David L Stevens Acked-by: Sowmini Varadhan Signed-off-by: David S.

sunvnet: improve error handling when a remote crashes

2015-01-27T08:25:21Z

If a remote machine crashes while there are pending transmit buffers, the sunvnet driver reallocates the ring descriptors giving us enries that have state VIO_DESC_FREE but also an allocated skb. This results in a BUG_ON() call when the remote reboots and we reach that point in the ring. This patch: 1) clears pending tx packets in the ring on port reset 2) changes a BUG_ON() to a pr_warn() when a remote host has given us an invalid descriptor state 3) collapses multiple active buffer frees in a ring to a single message per ring and adds the device name and remote MAC address This fixes the particular problem of not cleaning up pending buffers on a reset, but also prevents us from crashing if the remote handles descriptors out of order or sets an unexpected state for a descriptor.

sunvnet: free pending tx buffers before clearing ring data

2015-01-27T08:25:21Z

This patch moves the clearing of ring data in vnet_port_free_tx_bufs to after the freeing of pending buffers in the ring. Otherwise, this can result in dereferencing a NULL pointer. Reported-by: Sowmini Varadhan Signed-off-by: David L Stevens Signed-off-by: David S. Miller

sunvnet: fix rx packet length check to allow for TSO

2015-01-13T22:24:21Z

This patch fixes the rx packet length check in the sunvnet driver to allow for a TSO max packet length greater than the LDC channel negotiated MTU. These are negotiated separately and there is no requirement that port->tsolen be less than port->rmtu, but if it isn't, it'll drop packets with rx length errors.
