2015-08-23NET: nps_enet: drop control framesNoam Camus1-4/+4
We set controller to drop control frames and not trying to pass them on. This is only needed for debug reasons. Signed-off-by: Noam Camus <noamc@ezchip.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2015-08-23NET: nps_enet: TX done race conditionNoam Camus1-7/+3
We need to set tx_skb pointer before send frame. If we receive interrupt before we set pointer we will try to free SKB with wrong pointer. Now we are sure that SKB pointer will never be NULL during handling TX done and check is removed. Signed-off-by: Noam Camus <noamc@ezchip.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2015-08-23NET: nps_enet: replace use of cause registerNoam Camus2-24/+5
When interrupt is received we read directly from control register for RX/TX instead of reading cause register since this register fails to indicate TX done when TX interrupt is "edge mode". Signed-off-by: Noam Camus <noamc@ezchip.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2015-08-23fou: Do WARN_ON_ONCE in gue_gro_receive for bad proto callbacksTom Herbert1-1/+1

2015-08-23gro: Fix remcsum offload to deal with frags in GROTom Herbert3-42/+53

2015-08-23net: dsa: mv88e6xxx: set 802.1Q mode to FallbackVivien Didelot1-1/+1
The current Secure port mode requires the port-based VLANs to also be valid in the 802.1Q VLAN Table Unit. The current hardware bridging support only configures the port-based VLANs, thus is broken. A new patchset is required to adapt the hardware bridging code to fully support the Secure port mode. In the meantime, change the 802.1Q mode of every ports to Fallback, which filtering is more permissive, and doesn't add this restriction to handle port-based and tagged-based VLANs.

2015-08-20route: move lwtunnel state to dst_entryJiri Benc17-130/+48
Currently, the lwtunnel state resides in per-protocol data. This is a problem if we encapsulate ipv6 traffic in an ipv4 tunnel (or vice versa). The xmit function of the tunnel does not know whether the packet has been routed to it by ipv4 or ipv6, yet it needs the lwtstate data. Moving the lwtstate data to dst_entry makes such inter-protocol tunneling possible. As a bonus, this brings a nice diffstat.

2015-08-19netfilter: nft_payload: work around vlan header strippingFlorian Westphal1-1/+56
make payload expression aware of the fact that VLAN offload may have removed a vlan header. When we encounter tagged skb, transparently insert the tag into the register so that vlan header matching can work without userspace being aware of offload features.

2015-08-18target: Fix handling of small allocation lengths in REPORT LUNSRoland Dreier1-16/+16
REPORT LUNS should not fail just because the allocation length is less than 16. The relevant section of SPC-4 is: 4.2.5.6 Allocation length The ALLOCATION LENGTH field specifies the maximum number of bytes or blocks that an application client has allocated in the Data-In Buffer. The ALLOCATION LENGTH field specifies bytes unless a different requirement is stated in the command definition. An allocation length of zero specifies that no data shall be transferred. This condition shall not be considered an error. So we should just truncate our response rather than return an error.

2015-08-18vrf: simplify the netdev notifier functionNikolay Aleksandrov1-3/+2
We can drop the check because if vrf_ptr is present then we must have the vrf device as a master and since we're running with rtnl it can't go away. Signed-off-by: Nikolay Aleksandrov <nikolay@cumulusnetworks.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2015-08-18vrf: don't check for dstats and rth in uninit pathNikolay Aleksandrov1-4/+2
dstats and rth are always present because we fail the device registration if they can't be allocated in vrf_init() (ndo_init) so drop the unnecessary checks. Signed-off-by: Nikolay Aleksandrov <nikolay@cumulusnetworks.com> Signed-off-by: David S. Miller <davem@davemloft.net>
