* ip_tunnel: Set network header properly for IP_ECN_decapsulate()Ying Cai2014-05-051-0/+2
| | | | | | | | | | | | | | | | | | | | | In ip_tunnel_rcv(), set skb->network_header to inner IP header before IP_ECN_decapsulate(). Without the fix, IP_ECN_decapsulate() takes outer IP header as inner IP header, possibly causing error messages or packet drops. Note that this skb_reset_network_header() call was in this spot when the original feature for checking consistency of ECN bits through tunnels was added in eccc1bb8d4b4 ("tunnel: drop packet if ECN present with not-ECT"). It was only removed from this spot in 3d7b46cd20e3 ("ip_tunnel: push generic protocol handling to ip_tunnel module."). Fixes: 3d7b46cd20e3 ("ip_tunnel: push generic protocol handling to ip_tunnel module.")

Second expands the scope of a workaround to include i217 and i218 parts as well to address over aggressive transmit behavior when connecting at 10Mbs half-duplex. Next is to resolve a reported link flap issue on 82579 parts which was root caused as an interoperability problem between 82579 and at least some Broadcom PHYs in the Energy Efficient Ethernet wake mechanism. Lastly, restricts the workaround of putting the PHY into MDIO slow mode to access the PHY id to relevant parts since this issue has been fixed on the newer hardware. ==================== Signed-off-by: David S.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It has been determined that the workaround of putting the PHY into MDIO slow mode to access the PHY id is not necessary with Lynx Point and newer parts.

| * e1000e: Fix issue with link flap on 82579David Ertman2014-05-052-0/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Several customers have reported a link flap issue on 82579. The symptoms are random and intermittent link losses when 82579 is connected to specific link partners. Issue has been root caused as interoperability problem between 82579 and at least some Broadcom PHYs in the Energy Efficient Ethernet wake mechanism. To fix the issue, we are disabling the Phase Locked Loop shutdown in 100M Low Power Idle. This solution will cause an increase of power in 100M EEE link. It will cost additional 28mW in this specific mode.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is a workaround for a HW erratum on 82579 devices. Erratum is #23 in Intel 6 Series Chipset and Intel C200 Series Chipset specification Update June 2013. Problem: 82579 parts experience packet loss in Gig and 100 speeds when interconnect between PHY and MAC is exiting K1 power saving state. This was previously believed to only affect 1Gig speed, but has been observed at 100Mbs also. Workaround: Disable K1 for 82579 devices at Gig and 100 speeds.

This meant that frames of any size will be sent without additional padding, except for the single byte added if the size is a multiple of the USB packet size. But if the unpadded size is identical to the maximum frame size, and the maximum size is a multiplum of the USB packet size, then this one-byte padding will overflow the buffer. Prevent padding if already at maximum frame size, letting usbnet transmit a ZLP instead in this case.

Since the tx queueing rework, pausing per-tid queues on aggregation session setup is no longer necessary.

Enabling autosuspend for Intel Bluetooth devices has been shown to not work reliable. It does work for some people with certain combinations of USB host controllers, but for others it puts the device to sleep and it will not wake up for any event. These events can be important ones like HCI Inquiry Complete or HCI Connection Request. The events will arrive as soon as you poke the device with a new command, but that is not something we can do in these cases. Initially there were patches to the xHCI USB controller that fixed this for some people, but not for all. This could be well a problem somewhere in the USB subsystem or in the USB host controllers or just plain a hardware issue somewhere. At this moment we just do not know and the only safe action is to revert this patch.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Implement a recv budget so that in cases of high traffic we still allow other taskets to get processed. Without this, we can encounter a host of issues during high wireless traffic reception depending on system load including rcu stall's detected (ARM), soft lockups, failure to service critical tasks such as watchdog resets, and triggering of the tx stuck tasklet. The same thing was proposed previously by Ben: http://www.spinics.net/lists/linux-wireless/msg112891.html The only difference here is that I make sure only processed packets are counted in the budget by checking at the end of the rx loop.

* | gianfar: Avoid unnecessary reg accesses in adjust_link()Claudiu Manoil2014-04-301-110/+113
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For phy devices that don't issue interrupts upon link state changes, phylib polls the link state resulting in repeated calls to adjust_link(), even if the link state didn't change. As a result, some mac registers are repeatedly read and written with the same values, which is not ok. To fix this, adjust_link() has been refactored to check first whether the link state has changed and to take action only if needed, updating mac registers and local state variables. The 'new_state' local flag, set if one of the link params changed (link, speed or duplex), has been rendered useless and removed by this refactoring.

* | tcp_cubic: fix the range of delayed_ackLiu Yu2014-04-301-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | commit b9f47a3aaeab (tcp_cubic: limit delayed_ack ratio to prevent divide error) try to prevent divide error, but there is still a little chance that delayed_ack can reach zero. In case the param cnt get negative value, then ratio+cnt would overflow and may happen to be zero. As a result, min(ratio, ACK_RATIO_LIMIT) will calculate to be zero. In some old kernels, such as 2.6.32, there is a bug that would pass negative param, which then ultimately leads to this divide error. commit 5b35e1e6e9c (tcp: fix tcp_trim_head() to adjust segment count with skb MSS) fixed the negative param issue. However, it's safe that we fix the range of delayed_ack as well, to make sure we do not hit a divide by zero.

The commit above doesn't appear to be necessary any more as the checksums appear to be correctly computed/validated. Additionally the above commit breaks kvm configurations where one VM is using a device that support checksum offload (virtio) and the other VM does not. In this case, packets leaving virtio device will have CHECKSUM_PARTIAL set. The packets is forwarded to a macvtap that has offload features turned off. Since we use CHECKSUM_UNNECESSARY, the host does does not update the checksum and thus a bad checksum is passed up to the guest.

* | mactap: Fix checksum errors for non-gso packets in bridge modeVlad Yasevich2014-04-301-0/+9

On the other hand, e1000 does not support any acceleration. For small TCP packets (and this includes the 3-way handshake), e1000 ends up receiving packets that only have a partial checksum set. This causes TCP to fail checksum validation and to drop packets. As a result tcp connections can not be established. Commit 3e4f8b787370978733ca6cae452720a4f0c296b8 macvtap: Perform GSO on forwarding path. fixes this issue for large packets wthat will end up undergoing GSO. This commit adds a check for the non-GSO case and attempts to compute the checksum for partially checksummed packets in the non-GSO case.
