2014-03-29Input: mousedev - fix race when creating mixed deviceDmitry Torokhov
We should not be using static variable mousedev_mix in methods that can be called before that singleton gets assigned. While at it let's add open and close methods to mousedev structure so that we do not need to test if we are dealing with multiplexor or normal device and simply call appropriate method directly.

2014-03-29net: mvneta: use devm_ioremap_resource() instead of of_iomap()Thomas Petazzoni
The mvneta driver currently uses of_iomap(), which has two drawbacks: it doesn't request the resource, and it isn't devm-style so some error handling is needed. This commit switches to use devm_ioremap_resource() instead, which automatically requests the resource (so the I/O registers region shows up properly in /proc/iomem), and also is devm-style, which allows to get rid of some error handling to unmap the I/O registers region.

2014-03-29Input: don't modify the id of ioctl-provided ff effect on upload failureElias Vanderstuyft
If a new (id == -1) ff effect was uploaded from userspace, ff-core.c::input_ff_upload() will have assigned a positive number to the new effect id. Currently, evdev.c::evdev_do_ioctl() will save this new id to userspace, regardless of whether the upload succeeded or not. On upload failure, this can be confusing because the dev->ff->effects[] array will not contain an element at the index of that new effect id. This patch fixes this by leaving the id unchanged after upload fails. Note: Unfortunately applications should still expect changed effect id for quite some time. This has been discussed on: http://www.mail-archive.com/linux-input@vger.kernel.org/msg08513.html ("ff-core effect id handling in case of a failed effect upload") Suggested-by: Dmitry Torokhov <dmitry.torokhov@gmail.com> Signed-off-by: Elias Vanderstuyft <elias.vds@gmail.com> Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>
2014-03-29rbd: drop an unsafe assertionAlex Elder
Olivier Bonvalet reported having repeated crashes due to a failed assertion he was hitting in rbd_img_obj_callback(): Assertion failure in rbd_img_obj_callback() at line 2165: rbd_assert(which >= img_request->next_completion); With a lot of help from Olivier with reproducing the problem we were able to determine the object and image requests had already been completed (and often freed) at the point the assertion failed. There was a great deal of discussion on the ceph-devel mailing list about this. The problem only arose when there were two (or more) object requests in an image request, and the problem was always seen when the second request was being completed. The problem is due to a race in the window between setting the "done" flag on an object request and checking the image request's next completion value. When the first object request completes, it checks to see if its successor request is marked "done", and if so, that request is also completed. In the process, the image request's next_completion value is updated to reflect that both the first and second requests are completed. By the time the second request is able to check the next_completion value, it has been set to a value *greater* than its own "which" value, which caused an assertion to fail. Fix this problem by skipping over any completion processing unless the completing object request is the next one expected. Test only for inequality (not >=), and eliminate the bad assertion.

When mergeable buffers are disabled, and the incoming packet is too large for the rx buffer, get_rx_bufs returns success. This was intentional in order for make recvmsg truncate the packet and then handle_rx would detect err != sock_len and drop it. Unfortunately we pass the original sock_len to recvmsg - which means we use parts of iov not fully validated. Fix this up by detecting this overrun and doing packet drop immediately.

2014-03-28sh_eth: ensure pm_runtime cannot suspend the device during initBen Dooks
The pm_rumtime work queue is causing the device to be suspended during initialisation, thus the initialisation may not be able to access registers properly. As the code is called from a work queue, it is possible that this is not seen from certain configurations/builds due to the asynchronos nature of the code. Another issue has also been found where the network device registration calls back into the driver thus causing further pm_runtime calls that also caused issues with the MDIO bus code. This has now been checked and is the only place the MDIO can be called without the device open. Use pm_runtime_get_sync() and pm_runtime_put() to ensure that the pm system does not suspend it during the probe() call and remove the now unnecessary pm_runtime_resume() call. Also add a call in the error path to call pm_runtime_disable(). This fixes the external abort that can cause /sbin/init or other such init processed to die.

Cleans up add_del_fdir() because it was used and implemented only for the add, so change the name and drop a parameter. Adds the ability to drop a flow if we wanted to and adds a flow director message level to be used for flow director specific messages. Mitch fixes an issue on i40evf where the Tx watchdog handler was causing an oops when sending an admin queue message to request a reset because the admin queue functions use spinlocks. Greg provides a change to i40e to make the alloc and free queue vector calls orthogonal. Shannon fixes i40e to verify the eeprom checksum and firmware CRC status bits, and shutdown the driver if they fail. This change stops the processing of traffic, but does not kill the PF netdev so that the NVMUpdate process still has a chance at fixing the image. Also provides a fix to make sure the VSI has a netdev before trying to use it in the debugfs netdev_ops commands. Jakub Kicinski provides patches for e1000e and igb to fix a number issues found in the PTP code. v2: - drop patch 11 "i40e: Add a fallback debug flow for the driver" from the series based on feedback from David Miller ==================== Signed-off-by: David S.

2014-03-28Input: synaptics - add manual min/max quirkBenjamin Tissoires
The new Lenovo Haswell series (-40's) contains a new Synaptics touchpad. However, these new Synaptics devices report bad axis ranges. Under Windows, it is not a problem because the Windows driver uses RMI4 over SMBus to talk to the device. Under Linux, we are using the PS/2 fallback interface and it occurs the reported ranges are wrong. Of course, it would be too easy to have only one range for the whole series, each touchpad seems to be calibrated in a different way. We can not use SMBus to get the actual range because I suspect the firmware will switch into the SMBus mode and stop talking through PS/2 (this is the case for hybrid HID over I2C / PS/2 Synaptics touchpads). So as a temporary solution (until RMI4 land into upstream), start a new list of quirks with the min/max manually set.
