2017-12-12PCI: rcar: Fix use-after-free in probe error pathGeert Uytterhoeven
If CONFIG_DEBUG_SLAB=y, and no PCIe card is inserted, the kernel crashes during probe on r8a7791/koelsch: rcar-pcie fe000000.pcie: PCIe link down Unable to handle kernel paging request at virtual address 6b6b6b6b (seeing this message requires earlycon and keep_bootcon). Indeed, pci_free_host_bridge() frees the PCI host bridge, including the embedded rcar_pcie object, so pci_free_resource_list() must not be called afterwards. To fix this, move the call to pci_free_resource_list() up, and update the label name accordingly.

2017-12-12Revert "usb: gadget: allow to enable legacy drivers without USB_ETH"Felipe Balbi
This reverts commit 7a9618a22aadffb55027d665491adf466bced61a. Romain Izard recently reported that commit 7a9618a22aad ended up allowing every legacy gadget driver to statically linked to the kernel, however that doesn't work, since only one legacy gadget can be bound to a controller. Because of that, let's revert the original commit and fix the problem. Reported-by: Romain Izard <romain.izard.pro@gmail.com> Signed-off-by: Felipe Balbi <felipe.balbi@linux.intel.com>
2017-12-12usb: gadget: webcam: fix V4L2 Kconfig dependencyArnd Bergmann
Configuring the USB_G_WEBCAM driver as built-in leads to a link error when CONFIG_VIDEO_V4L2 is a loadable module: drivers/usb/gadget/function/f_uvc.o: In function `uvc_function_setup': f_uvc.c:(.text+0xfe): undefined reference to `v4l2_event_queue' drivers/usb/gadget/function/f_uvc.o: In function `uvc_function_ep0_complete': f_uvc.c:(.text+0x188): undefined reference to `v4l2_event_queue' This changes the Kconfig dependency to disallow that configuration, and force it to be a module in that case as well.

2017-12-12pinctrl: cherryview: Mask all interrupts on Intel_Strago based systemsMika Westerberg
Guenter Roeck reported an interrupt storm on a prototype system which is based on Cyan Chromebook. The root cause turned out to be a incorrectly configured pin that triggers spurious interrupts. This will be fixed in coreboot but currently we need to prevent the interrupt storm from happening by masking all interrupts (but not GPEs) on those systems.

2017-12-11scsi: core: Fix a scsi_show_rq() NULL pointer dereferenceBart Van Assche
Avoid that scsi_show_rq() triggers a NULL pointer dereference if called after sd_uninit_command(). Swap the NULL pointer assignment and the mempool_free() call in sd_uninit_command() to make it less likely that scsi_show_rq() triggers a use-after-free. Note: even with these changes scsi_show_rq() can trigger a use-after-free but that's a lesser evil than e.g. suppressing debug information for T10 PI Type 2 commands completely.

2017-12-11scsi: libsas: fix length error in sas_smp_handler()Jason Yan
The return value of smp_execute_task_sg() is the untransferred residual, but bsg_job_done() requires the length of payload received. This makes SMP passthrough commands from userland by sg ioctl to libsas get a wrong response. The userland tools such as smp_utils failed because of these wrong responses: ~#smp_discover /dev/bsg/expander-2\:13 response too short, len=0 ~#smp_discover /dev/bsg/expander-2\:134 response too short, len=0 Fix this by passing the actual received length to bsg_job_done(). And if smp_execute_task_sg() returns 0, this means received length is exactly the buffer length.

2017-12-11iw_cxgb4: only insert drain cqes if wq is flushedSteve Wise
Only insert our special drain CQEs to support ib_drain_sq/rq() after the wq is flushed. Otherwise, existing but not yet polled CQEs can be returned out of order to the user application. This can happen when the QP has exited RTS but not yet flushed the QP, which can happen during a normal close (vs abortive close). In addition never count the drain CQEs when determining how many CQEs need to be synthesized during the flush operation. This latter issue should never happen if the QP is properly flushed before inserting the drain CQE, but I wanted to avoid corrupting the CQ state. So we handle it and log a warning once.

2017-12-11net: sh_eth: do not advertise Gigabit capabilities when not availableThomas Petazzoni
Not all variants of the sh_eth hardware have Gigabit support. Unfortunately, the current driver doesn't tell the PHY about the limited MAC capabilities. Due to this, if you have a Gigabit capable PHY, the PHY will advertise its Gigabit capability and establish a link at 1Gbit/s, even though the MAC doesn't support it. In order to avoid this, we use the recently introduced phy_set_max_speed() to tell the PHY to not advertise speed higher than 100 MBit/s. Tested on a SH7786 platform, with a Gigabit PHY.

2017-12-11net: phy: meson-gxl: detect LPA corruptionJerome Brunet
The purpose of this change is to fix the incorrect detection of the link partner (LP) advertised capabilities which sometimes happens with this PHY (roughly 1 time in a dozen) This issue may cause the link to be negotiated at 10Mbps/Full or 10Mbps/Half when 100MBps/Full is actually possible. In some case, the link is even completely broken and no communication is possible. To detect the corruption, we must look for a magic undocumented bit in the WOL bank (hint given by the SoC vendor kernel) but this is not enough to cover all cases. We also have to look at the LPA ack. If the LP supports Aneg but did not ack our base code when aneg is completed, we assume something went wrong. The detection of a corrupted LPA triggers a restart of the aneg process. This solves the problem but may take up to 6 retries to complete.

2017-12-11PM / sleep: Avoid excess pm_runtime_enable() calls in device_resume()Rafael J. Wysocki
Middle-layer code doing suspend-time optimizations for devices with the DPM_FLAG_SMART_SUSPEND flag set (currently, the PCI bus type and the ACPI PM domain) needs to make the core skip ->thaw_early and ->thaw callbacks for those devices in some cases and it sets the power.direct_complete flag for them for this purpose. However, it turns out that setting power.direct_complete outside of the PM core is a bad idea as it triggers an excess invocation of pm_runtime_enable() in device_resume(). For this reason, provide a helper to clear power.is_late_suspended and power.is_suspended to be invoked by the middle-layer code in question instead of setting power.direct_complete and make that code call the new helper.

2017-12-11dmaengine: dmatest: move callback wait queue to thread contextAdam Wallis
Commit adfa543e7314 ("dmatest: don't use set_freezable_with_signal()") introduced a bug (that is in fact documented by the patch commit text) that leaves behind a dangling pointer. Since the done_wait structure is allocated on the stack, future invocations to the DMATEST can produce undesirable results (e.g., corrupted spinlocks). Commit a9df21e34b42 ("dmaengine: dmatest: warn user when dma test times out") attempted to WARN the user that the stack was likely corrupted but did not fix the actual issue. This patch fixes the issue by pushing the wait queue and callback structs into the the thread structure. If a failure occurs due to time, dmaengine_terminate_all will force the callback to safely call wake_up_all() without possibility of using a freed pointer.

This controller does not support EEE, but it may connect to a PHY which supports EEE and advertises EEE by default, while its link partner also advertises EEE. If this happens, the PHY enters low power mode when the traffic rate is low and causes packet loss. This patch disables EEE advertisement by default for any PHY that gianfar connects to, to prevent the above unwanted outcome.
