commit "ip_gre: allow CSUM capable devices to handle packets" aa0e51cdda005cd37e2, broke GRE_CSUM case. GRE_CSUM needs checksum computed for inner packet.

2013-02-25IPoIB: Free ipoib neigh on path record failure so path rec queries are retriedRoland Dreier1-0/+3
If IPoIB fails to look up a path record (eg if it tries during an SM failover when one SM is dead but the new one hasn't taken over yet), the driver ends up with a neighbour structure but no address handle (AH). There's no mechanism to recover from this: any further packets sent to this destination will be silently dumped in ipoib_start_xmit(). Fix this by freeing the neighbour structures when a path rec query fails, so that the next packet queued to be sent will trigger a new path record query.

2013-02-25IB/srp: Fail I/O requests if the transport is offlineBart Van Assche2-0/+8
If an SRP target is no longer reachable and srp_reset_host() fails to reconnect then ib_srp will invoke scsi_remove_host(). That function will invoke __scsi_remove_device() for each LUN. And that last function will change the device state from SDEV_TRANSPORT_OFFLINE into SDEV_CANCEL. Certain user space software, e.g. older versions of multipathd, continue queueing I/O to SCSI devices that are in the SDEV_CANCEL state. If these I/O requests are submitted as SG_IO that means that the REQ_PREEMPT flag will be set and hence that these requests will be passed to srp_queuecommand(). These requests will time out. If new requests are queued fast enough from user space these active requests will prevent __scsi_remove_device() to finish. Avoid this by failing I/O requests in the SDEV_CANCEL state if the transport is offline. Introduce a new variable to keep track of the transport state instead of failing requests if (!target->connected || target->qp_in_error), so that the SCSI error handler has a chance to retry commands after a transport layer failure occurred.

2013-02-25IB/srp: Avoid endless SCSI error handling loopBart Van Assche1-14/+15
If a SCSI command times out it is passed to the SCSI error handler. The SCSI error handler will try to abort the commands that timed out. If aborting fails, a device reset will be attempted. If the device reset also fails a host reset will be attempted. If the host reset also fails the whole procedure will be repeated. srp_abort() and srp_reset_device() fail for a QP in the error state. srp_reset_host() fails after host removal has started. Hence if the SCSI error handler gets invoked after host removal has started and with the QP in the error state an endless loop will be triggered. Modify the SCSI error handling functions in ib_srp as follows: - Abort SCSI commands properly even if the QP is in the error state. - Make srp_reset_host() reset SCSI requests even after host removal has already started or if reconnecting fails.

Then commit b1a925f44a3a ("tty vt: Fix a regression in command line edition") partially fixed it. However, the buffer being moved is still too large and overflowing beyond the end of the current line, corrupting existing characters on the next line. Example test case: echo -e "abc\nde\x1b[A\x1b[4h \x1b[4l\x1b[B" Expected result: ab c de Current result: ab c e Needless to say that this is very annoying when inserting words in the middle of paragraphs with certain text editors.

2013-02-24vmxnet3: fix ethtool ring buffer size settingNeil Horman1-4/+2
Noticed that vmxnet3's get_ringparam function was returning the summation of all ring buffers on a NIC, rather than just the size of any one ring. This causes problems when a vmxnet3 instance has multiple queues, as ethtool, when setting ring parameters, first gets the current ring parameters to set the existing values in the set_ringparm commannd. The result is, that unless both rx and tx ring sizes are set in a single operation, which ever ring is not set will silently have its ring count multiplied by the number of queues on the NIC until it reaches a driver defined maxiumum value. Fix it by not multiplying the rx and tx ring sizes by the number of queues in the system, like every other driver. Tested by myself successfully.

2013-02-24mmc: tegra: assume CONFIG_OF, remove platform dataStephen Warren2-102/+45
Tegra only supports, and always enables, device tree. Remove all ifdefs and runtime checks for DT support from the driver. Platform data is therefore no longer required. Rework the driver to parse the device tree directly into struct sdhci_tegra. Signed-off-by: Stephen Warren <swarren@nvidia.com> Signed-off-by: Chris Ball <cjb@laptop.org>
2013-02-24mmc: add DT bindings for more MMC capability flagsGuennadi Liakhovetski2-0/+17
Many MMC capability flags are platform-dependent and are traditionally set in platform data. With DT often each such capability requires a special binding. Add bindings for MMC_CAP_SD_HIGHSPEED, MMC_CAP_MMC_HIGHSPEED, MMC_CAP_POWER_OFF_CARD and MMC_CAP_SDIO_IRQ capabilities. Also add code to DT parser to look up "keep-power-in-suspend" and "enable-sdio-wakeup" bindings and set MMC_PM_KEEP_POWER and MMC_PM_WAKE_SDIO_IRQ respectively, if found.

2013-02-24mmc: tmio: add support for the VccQ regulatorGuennadi Liakhovetski1-10/+46
Some SD/MMC interfaces use 2 power regulators: one to power the card itself (Vcc) and another one to pull signal lines up (VccQ). In case of eMMC and UHS SD cards the regulators also have to be configured to supply different voltages. The preferred order of turning supply power on and off is to turn Vcc first on and last off.
