2017-12-05s390/dasd: prevent prefix I/O errorStefan Haberland1-6/+10
Prevent that a prefix flag is set based on invalid configuration data. The validity.verify_base flag should only be set for alias devices. Usually the unit address type is either one of base, PAV alias or HyperPAV alias. But in cases where the unit address type is not set or any other value the validity.verify_base flag might be set as well. This would lead to follow on errors. Explicitly check for alias devices and set the validity flag only for them.

2017-12-05s390/dasd: remove 'struct timespec' usageArnd Bergmann2-6/+6
getnstimeofday() and timespec are deprecated since they can overflow on 32-bit architectures. This simply changes to the explicitly typed timespec64 version that doesn't have that problem. It would be nice to also convert to monotonic timestamps and call ktime_get_ts64() rather than ktime_get_real_ts64(), but that would be a user-visible change.

2017-12-03stmmac: reset last TSO segment size after device openLars Persson1-0/+1
The mss variable tracks the last max segment size sent to the TSO engine. We do not update the hardware as long as we receive skb:s with the same value in gso_size. During a network device down/up cycle (mapped to stmmac_release() and stmmac_open() callbacks) we issue a reset to the hardware and it forgets the setting for mss. However we did not zero out our mss variable so the next transmission of a gso packet happens with an undefined hardware setting. This triggers a hang in the TSO engine and eventuelly the netdev watchdog will bark.

The current GSO skb size limit was copy&pasted over from the L3 path, where it is needed due to a TSO limitation. As L2 devices don't offer TSO support (and thus all GSO skbs are segmented before they reach the driver), there's no reason to restrict the stack in how large it may build the GSO skbs.

2017-12-02s390/qeth: fix GSO throughput regressionJulian Wiedmann4-0/+38
Using GSO with small MTUs currently results in a substantial throughput regression - which is caused by how qeth needs to map non-linear skbs into its IO buffer elements: compared to a linear skb, each GSO-segmented skb effectively consumes twice as many buffer elements (ie two instead of one) due to the additional header-only part. This causes the Output Queue to be congested with low-utilized IO buffers. Fix this as follows: If the MSS is low enough so that a non-SG GSO segmentation produces order-0 skbs (currently ~3500 byte), opt out from NETIF_F_SG. This is where we anticipate the biggest savings, since an SG-enabled GSO segmentation produces skbs that always consume at least two buffer elements. Larger MSS values continue to get a SG-enabled GSO segmentation, since 1) the relative overhead of the additional header-only buffer element becomes less noticeable, and 2) the linearization overhead increases. With the throughput regression fixed, re-enable NETIF_F_SG by default to reap the significant CPU savings of GSO.

2017-12-02s390/qeth: fix thinko in IPv4 multicast address trackingJulian Wiedmann1-0/+1
Commit 5f78e29ceebf ("qeth: optimize IP handling in rx_mode callback") reworked how secondary addresses are managed for qeth devices. Instead of dropping & subsequently re-adding all addresses on every ndo_set_rx_mode() call, qeth now keeps track of the addresses that are currently registered with the HW. On a ndo_set_rx_mode(), we thus only need to do (de-)registration requests for the addresses that have actually changed. On L3 devices, the lookup for IPv4 Multicast addresses checks the wrong hashtable - and thus never finds a match. As a result, we first delete *all* such addresses, and then re-add them again. So each set_rx_mode() causes a short period where the IPv4 Multicast addresses are not registered, and the card stops forwarding inbound traffic for them. Fix this by setting the ->is_multicast flag on the lookup object, thus enabling qeth_l3_ip_from_hash() to search the correct hashtable and find a match there.

2017-12-02vhost: fix skb leak in handle_rx()Wei Xu1-10/+10
Matthew found a roughly 40% tcp throughput regression with commit c67df11f(vhost_net: try batch dequing from skb array) as discussed in the following thread: https://www.mail-archive.com/netdev@vger.kernel.org/msg187936.html Eventually we figured out that it was a skb leak in handle_rx() when sending packets to the VM. This usually happens when a guest can not drain out vq as fast as vhost fills in, afterwards it sets off the traffic jam and leaks skb(s) which occurs as no headcount to send on the vq from vhost side. This can be avoided by making sure we have got enough headcount before actually consuming a skb from the batched rx array while transmitting, which is simply done by moving checking the zero headcount a bit ahead.

2017-12-02bnxt_en: Need to unconditionally shut down RoCE in bnxt_shutdownRay Jui1-1/+2
The current 'bnxt_shutdown' implementation only invokes 'bnxt_ulp_shutdown' to shut down RoCE in the case when the system is in the path of power off (SYSTEM_POWER_OFF). While this may work in most cases, it does not work in the smart NIC case, when Linux 'reboot' command is initiated from the Linux that runs on the ARM cores of the NIC card. In this particular case, Linux 'reboot' results in a system 'L3' level reset where the entire ARM and associated subsystems are being reset, but at the same time, Nitro core is being kept in sane state (to allow external PCIe connected servers to continue to work). Without properly shutting down RoCE and freeing all associated resources, it results in the ARM core to hang immediately after the 'reboot' By always invoking 'bnxt_ulp_shutdown' in 'bnxt_shutdown', it fixes the above issue Fixes: 0efd2fc65c92 ("bnxt_en: Add a callback to inform RDMA driver during PCI shutdown.")

2017-12-01can: mcba_usb: fix device disconnect bugMartin Kelly1-0/+1
Currently, when you disconnect the device, the driver infinitely resubmits all URBs, so you see: Rx URB aborted (-32) in an infinite loop. Fix this by catching -EPIPE (what we get in urb->status when the device disconnects) and not resubmitting. With this patch, I can plug and unplug many times and the driver recovers correctly.

2017-12-01can: peak/pci: fix potential bug when probe() failsStephane Grosjean2-2/+8
PCI/PCIe drivers for PEAK-System CAN/CAN-FD interfaces do some access to the PCI config during probing. In case one of these accesses fails, a POSITIVE PCIBIOS_xxx error code is returned back. This POSITIVE error code MUST be converted into a NEGATIVE errno for the probe() function to indicate it failed. Using the pcibios_err_to_errno() function, we make sure that the return code will always be negative.

The conditon in the while-loop becomes true when actual_length is less than 2 (MSG_HEADER_LEN). In best case we end up with a former, already dispatched msg, that got msg->len greater than actual_length. This will result in a "Format error" error printout.
