hyperv: Fix the error processing in netvsc_send()

2015-02-01T01:31:49Z

The existing code frees the skb in EAGAIN case, in which the skb will be retried from upper layer and used again. Also, the existing code doesn't free send buffer slot in error case, because there is no completion message for unsent packets. This patch fixes these problems. (Please also include this patch for stable trees. Thanks!) Signed-off-by: Haiyang Zhang Reviewed-by: K. Y. Srinivasan Signed-off-by: David S. Miller

hyperv: Fix some variable name typos in send-buffer init/revoke

2014-12-22T21:11:11Z

The changed names are union fields with the same size, so the existing code still works. But, we now update these variables to the correct names. Signed-off-by: Haiyang Zhang Reviewed-by: K. Y. Srinivasan Signed-off-by: David S. Miller

hyperv: Add support for vNIC hot removal

2014-12-09T01:24:11Z

This patch adds proper handling of the vNIC hot removal event, which includes a rescind-channel-offer message from the host side that triggers vNIC close and removal. In this case, the notices to the host during close and removal is not necessary because the channel is rescinded. This patch blocks these unnecessary messages, and lets vNIC removal process complete normally. Signed-off-by: Haiyang Zhang Reviewed-by: K. Y. Srinivasan Signed-off-by: David S. Miller

net: Hyper-V: Deletion of an unnecessary check before the function call "vfree"

2014-11-25T22:22:48Z

The vfree() function performs also input parameter validation. Thus the test around the call is not needed. This issue was detected by using the Coccinelle software. Signed-off-by: Markus Elfring Signed-off-by: Haiyang Zhang Signed-off-by: David S. Miller

hyperv: Add processing of MTU reduced by the host

2014-11-12T21:21:36Z

If the host uses packet encapsulation feature, the MTU may be reduced by the host due to headroom reservation for encapsulation. This patch handles this new MTU value. Signed-off-by: Haiyang Zhang Signed-off-by: David S. Miller

hyperv: Add IPv6 into the hash computation for vRSS

2014-10-30T20:10:04Z

This will allow the workload spreading via vRSS for IPv6. Signed-off-by: Haiyang Zhang Reviewed-by: K. Y. Srinivasan Signed-off-by: David S. Miller

hyperv: Fix the total_data_buflen in send path

2014-10-22T21:58:50Z

total_data_buflen is used by netvsc_send() to decide if a packet can be put into send buffer. It should also include the size of RNDIS message before the Ethernet frame. Otherwise, a messge with total size bigger than send_section_size may be copied into the send buffer, and cause data corruption.

hyperv: Add handling of IP header with option field in netvsc_set_hash()

2014-10-18T03:43:40Z

In case that the IP header has optional field at the end, this patch will get the port numbers after that field, and compute the hash. The general parser skb_flow_dissect() is used here. Signed-off-by: Haiyang Zhang Reviewed-by: K. Y. Srinivasan Signed-off-by: David S. Miller

hyperv: Fix a bug in netvsc_send()

2014-10-06T01:10:48Z

After the packet is successfully sent, we should not touch the packet as it may have been freed. This patch is based on the work done by Long Li . David, please queue this up for stable. Signed-off-by: K. Y. Srinivasan Reported-by: Sitsofe Wheeler Signed-off-by: David S. Miller
