2016-02-04xhci: harden xhci_find_next_ext_cap against device removalJoe Lawrence1-0/+4
xhci_find_next_ext_cap doesn't check for PCI hotplug removal and may use the PCI master abort bit pattern (~0) to calculate a new PCI address offset to read/write. The has lead to reproducable crashes when testing surprise removal during device initialization on a Stratus platform, at least after commit d5ddcdf4d672 ("xhci: rework xhci extended capability list parsing functions"). The crash is repeatable on a Stratus platform when injecting hardware faults to induce xHCI host controller hotplug during driver initialization. If a PCI read in xhci_find_next_ext_cap returns the master abort pattern, quirk_usb_handoff_xhci may start using a bogus ext_cap_offset to start searching more bogus PCI addresses.

2016-02-04ARM: nomadik: fix up SD/MMC DT settingsLinus Walleij1-17/+20
The DTSI file for the Nomadik does not properly specify how the PL180 levelshifter is connected: the Nomadik actually needs all the five st,sig-dir-* flags set to properly control all lines out. Further this board supports full power cycling of the card, and since this variant has no hardware clock gating, it needs a ridiculously low frequency setting to keep up with the ever overflowing FIFO. The pin configuration set-up is a bit of a mystery, because of course these pins are a mix of inputs and outputs. However the reference implementation sets all pins to "output" with unspecified initial value, so let's do that here as well.

2016-02-04ALSA: timer: Fix leftover link at closingTakashi Iwai1-2/+2
In ALSA timer core, the active timer instance is managed in active_list linked list. Each element is added / removed dynamically at timer start, stop and in timer interrupt. The problem is that snd_timer_interrupt() has a thinko and leaves the element in active_list when it's the last opened element. This eventually leads to list corruption or use-after-free error. This hasn't been revealed because we used to delete the list forcibly in snd_timer_stop() in the past. However, the recent fix avoids the double-stop behavior (in commit [f784beb75ce8: ALSA: timer: Fix link corruption due to double start or stop]), and this leak hits reality. This patch fixes the link management in snd_timer_interrupt(). Now it simply unlinks no matter which stream is.

2016-02-04[media] vb2-core: call threadio->fnc() if !VB2_BUF_STATE_ERRORMauro Carvalho Chehab1-1/+1
changeset 70433a152f0 ("media: videobuf2: Refactor vb2_fileio_data and vb2_thread") broke videobuf2-dvb. The root cause is that, instead of calling threadio->fnc() for all types of events except for VB2_BUF_STATE_ERROR, it was calling it only for VB2_BUF_STATE_DONE. With that, the DVB thread were never called. Cc: [email protected] # Kernel >= 4.3 Signed-off-by: Mauro Carvalho Chehab <[email protected]>
2016-02-04[media] vb2: fix nasty vb2_thread regressionHans Verkuil3-54/+46
The vb2_thread implementation was made generic and was moved from videobuf2-v4l2.c to videobuf2-core.c in commit af3bac1a. Unfortunately that clearly was never tested since it broke read() causing NULL address references. The root cause was confused handling of vb2_buffer vs v4l2_buffer (the pb pointer in various core functions). The v4l2_buffer no longer exists after moving the code into the core and it is no longer needed. However, the vb2_thread code passed a pointer to a vb2_buffer to the core functions were a v4l2_buffer pointer was expected and vb2_thread expected that the vb2_buffer fields would be filled in correctly. This is obviously wrong since v4l2_buffer != vb2_buffer. Note that the pb pointer is a void pointer, so no type-checking took place. This patch fixes this problem: 1) allow pb to be NULL for vb2_core_(d)qbuf. The vb2_thread code will use a NULL pointer here since they don't care about v4l2_buffer anyway. 2) let vb2_core_dqbuf pass back the index of the received buffer. This is all vb2_thread needs: this index is the index into the q->bufs array and vb2_thread just gets the vb2_buffer from there. 3) the fileio->b pointer (that originally contained a v4l2_buffer) is removed altogether since it is no longer needed.

This reverts commit e210c422b6fd ("xhci: don't finish a TD if we get a short transfer event mid TD") Turns out that most host controllers do not follow the xHCI specs and never send the second event for the last TRB in the TD if there was a short event mid-TD. Returning the URB directly after the first short-transfer event is far better than never returning the URB. (class drivers usually timeout after 30sec). For the hosts that do send the second event we will go back to treating it as misplaced event and print an error message for it.

2016-02-03Revert "usb: dwc2: Move reset into dwc2_get_hwparams()"John Youn2-9/+7
This reverts commit 263b7fb557f7 ("usb: dwc2: Move reset into dwc2_get_hwparams()") due to regression found on bcm2835 platform.

2016-02-03PM: Avoid false-positive warnings in dev_pm_domain_set()Rafael J. Wysocki1-1/+1
There is a WARN_ON() in dev_pm_domain_set() that triggers on attempts to set the pm_domain pointer for devices with a driver bound. However, that WARN_ON() triggers on attempts to clear the pointer too and the test it uses is based on checking the device's p->knode_driver pointer which still is set when the device bus type's/driver's ->remove callback has been executed. This leads to false-positive warnings when bus type code calls dev_pm_domain_set() to clear the pm_domain pointer after invoking the driver's ->remove() callback. To avoid those false-positives, make dev_pm_domain_set() check if the pointer passed to it is NULL and skip the warning in that case.

The commit 7d32cdef5356 ("usb: musb: fail with error when no DMA controller set"), caused the core platform driver to correctly return an error code when fail probing. Unfurtante it also caused bug for a NULL pointer dereference, during system suspend for the ux500 driver. The reason is a lacking validation of the corresponding ->driver_data pointer, which won't be set when the musb core driver fails to probe (or haven't yet been probed).

2016-02-03usb: phy: msm: fix error handling in probe.Srinivas Kandagatla1-13/+24
This driver registers for extcon events as part of its probe, but never unregisters them in case of error in the probe path. There were multiple issues noticed due to this missing error handling. One of them is random crashes if the regulators are not ready yet by the time probe is invoked. Ivan's previous attempt [1] to fix this issue, did not really address all the failure cases like regualtor/get_irq failures.

Trinity is now hitting the WARN_ON_ONCE we added in v3.15 commit cda540ace6a1 ("mm: get_user_pages(write,force) refuse to COW in shared areas"). The warning has served its purpose, nobody was harmed by that change, so just remove the warning to generate less noise from Trinity. Which reminds me of the comment I wrongly left behind with that commit (but was spotted at the time by Kirill), which has since moved into a separate function, and become even more obscure: delete it.

2016-02-03ipmi: put acpi.h with the other headersTony Camuso1-2/+1
Enclosing '#include <linux/acpi.h>' within '#ifdef CONFIG_ACPI' is unnecessary, since it has its own conditional compile for CONFIG_ACPI. Commit 0fbcf4af7c83 ("ipmi: Convert the IPMI SI ACPI handling to a platform device") exposed this as a problem for platforms that do not support ACPI when it introduced a call to ACPI_PTR() macro outside of the CONFIG_ACPI conditional compile. This would have been perfectly acceptable if acpi.h were not conditionally excluded for the non-acpi platform, because the conditional compile within acpi.h defines ACPI_PTR() to return NULL when compiled for non acpi platforms.
