2015-12-23net: cdc_ncm: avoid changing RX/TX buffers on MTU changesBjørn Mork
NCM buffer sizes are negotiated with the device independently of the network device MTU. The RX buffers are allocated by the usbnet framework based on the rx_urb_size value set by cdc_ncm. A single RX buffer can hold a number of MTU sized packets. The default usbnet change_mtu ndo only modifies rx_urb_size if it is equal to hard_mtu. And the cdc_ncm driver will set rx_urb_size and hard_mtu independently of each other, based on dwNtbInMaxSize and dwNtbOutMaxSize respectively. It was therefore assumed that usbnet_change_mtu() would never touch rx_urb_size. This failed to consider the case where dwNtbInMaxSize and dwNtbOutMaxSize happens to be equal. Fix by implementing an NCM specific change_mtu ndo, modifying the netdev MTU without touching the buffer size settings. Signed-off-by: Bjørn Mork <bjorn@mork.no> Signed-off-by: David S.

Commit 1299653affa4 ("sh_eth: fix descriptor access endianness") only addressed the 32-bit buffer address field byte-swapping but the driver still accesses 16-bit frame/buffer length descriptor fields without the necessary byte-swapping -- which should affect the big-endian kernels. In order to be able to use {cpu|edmac}_to_{edmac|cpu}(), we need to declare the RX/TX descriptor word 1 as a 32-bit field and use shifts/masking to access the 16-bit subfields (which gets rid of the ugly #ifdef'ery too)...

2015-12-22veth: don’t modify ip_summed; doing so treats packets with bad checksums ↵Vijay Pandurangan
as good. Packets that arrive from real hardware devices have ip_summed == CHECKSUM_UNNECESSARY if the hardware verified the checksums, or CHECKSUM_NONE if the packet is bad or it was unable to verify it. The current version of veth will replace CHECKSUM_NONE with CHECKSUM_UNNECESSARY, which causes corrupt packets routed from hardware to a veth device to be delivered to the application. This caused applications at Twitter to receive corrupt data when network hardware was corrupting packets. We believe this was added as an optimization to skip computing and verifying checksums for communication between containers. However, locally generated packets have ip_summed == CHECKSUM_PARTIAL, so the code as written does nothing for them. As far as we can tell, after removing this code, these packets are transmitted from one stack to another unmodified (tcpdump shows invalid checksums on both sides, as expected), and they are delivered correctly to applications. We didn’t test every possible network configuration, but we tried a few common ones such as bridging containers, using NAT between the host and a container, and routing from hardware devices to containers. We have effectively deployed this in production at Twitter (by disabling RX checksum offloading on veth devices). This code dates back to the first version of the driver, commit <e314dbdc1c0dc6a548ecf> ("[NET]: Virtual ethernet device driver"), so I suspect this bug occurred mostly because the driver API has evolved significantly since then. Commit <0b7967503dc97864f283a> ("net/veth: Fix packet checksumming") (in December 2010) fixed this for packets that get created locally and sent to hardware devices, by not changing CHECKSUM_PARTIAL. However, the same issue still occurs for packets coming in from hardware devices.

2015-12-22fm10k: Cleanup exception handling for changing queuesAlexander Duyck
This patch is meant to cleanup the exception handling for the paths where we reset the interrupts and then reconfigure them. In all of these paths we had very different levels of exception handling. I have updated the driver so that all of the paths should result in a similar state if we fail. Specifically the driver will now unload the mailbox interrupt, free the queue vectors and MSI-X, and then detach the interface. In addition for any of the PCIe related resets I have added a check with the hw_ready function to just make sure the registers are in a readable state prior to reopening the interface.
