2016-05-10USB: serial: mxuport: fix use-after-free in probe error pathJohan Hovold1-0/+10
The interface read and event URBs are submitted in attach, but were never explicitly unlinked by the driver. Instead the URBs would have been killed by usb-serial core on disconnect. In case of a late probe error (e.g. due to failed minor allocation), disconnect is never called and we could end up with active URBs for an unbound interface. This in turn could lead to deallocated memory being dereferenced in the completion callbacks.

2016-05-10USB: serial: keyspan: fix use-after-free in probe error pathJohan Hovold1-0/+4
The interface instat and indat URBs were submitted in attach, but never unlinked in release before deallocating the corresponding transfer buffers. In the case of a late probe error (e.g. due to failed minor allocation), disconnect would not have been called before release, causing the buffers to be freed while the URBs are still in use. We'd also end up with active URBs for an unbound interface.

2016-05-10USB: serial: io_edgeport: fix memory leaks in probe error pathJohan Hovold1-7/+10
URBs and buffers allocated in attach for Epic devices would never be deallocated in case of a later probe error (e.g. failure to allocate minor numbers) as disconnect is then never called. Fix by moving deallocation to release and making sure that the URBs are first unlinked.

2016-04-22drm/amdgpu: forbid mapping of userptr bo through radeon device fileJérôme Glisse1-0/+2
Allowing userptr bo which are basicly a list of page from some vma (so either anonymous page or file backed page) would lead to serious corruption of kernel structures and counters (because we overwrite the page->mapping field when mapping buffer). This will already block if the buffer was populated before anyone does try to mmap it because then TTM_PAGE_FLAG_SG would be set in in the ttm_tt flags. But that flag is check before ttm_tt_populate in the ttm vm fault handler. So to be safe just add a check to verify_access() callback.

2016-04-22drm/dp/mst: Validate port in drm_dp_payload_send_msg()cpaul@redhat.com1-1/+8
With the joys of things running concurrently, there's always a chance that the port we get passed in drm_dp_payload_send_msg() isn't actually valid anymore.

git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm Pull power management fixes from Rafael Wysocki: "Two fixes for issues introduced recently, one for an intel_pstate driver problem uncovered by the recent switch over from using timers and the other one for a potential cpufreq core problem related to system suspend/resume. Specifics: - Fix an intel_pstate driver problem causing CPUs to get stuck in the highest P-state when completely idle uncovered by the recent switch over from using timers (Rafael Wysocki). - Avoid attempts to get the current CPU frequency when all devices (like I2C controllers that may be nedded for that purpose) have been suspended during system suspend/resume (Rafael Wysocki)" * tag 'pm+acpi-4.6-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: cpufreq: Abort cpufreq_update_current_freq() for cpufreq_suspended set intel_pstate: Avoid getting stuck in high P-states when idle
2016-04-22rtc: ds1307: Use irq when available for wakeup-source deviceNishanth Menon1-1/+1
With commit 8bc2a40730ec ("rtc: ds1307: add support for the DT property 'wakeup-source'") we lost the ability for rtc irq functionality for devices that are actually hooked on a real IRQ line and have capability to wakeup as well. This is not an expected behavior. So, instead of just not requesting IRQ, skip the IRQ requirement only if interrupts are not defined for the device.

2016-04-22rtc: ds1307: ds3231 temperature s16 overflowZhuang Yuyao1-2/+2
while retrieving temperature from ds3231, the result may be overflow since s16 is too small for a multiplication with 250. ie. if temp_buf[0] == 0x2d, the result (s16 temp) will be negative.

2016-04-21atl2: Disable unimplemented scatter/gather featureBen Hutchings1-1/+1
atl2 includes NETIF_F_SG in hw_features even though it has no support for non-linear skbs. This bug was originally harmless since the driver does not claim to implement checksum offload and that used to be a requirement for SG. Now that SG and checksum offload are independent features, if you explicitly enable SG *and* use one of the rare protocols that can use SG without checkusm offload, this potentially leaks sensitive information (before you notice that it just isn't working). Therefore this obscure bug has been designated CVE-2016-2117.

2016-04-21irqchip/mips-gic: Don't overrun pcpu_masks arrayPaul Burton1-2/+2
Commit 2a0787051182 ("irqchip/mips-gic: Use gic_vpes instead of NR_CPUS") & commit 78930f09b940 ("irqchip/mips-gic: Clear percpu_masks correctly when mapping") both introduce code which accesses gic_vpes entries in the pcpu_masks array. However, this array has length NR_CPUS. If NR_CPUS is less than gic_vpes (ie. the kernel supports use of less CPUs than are present in the system) then we overrun the array, clobber some other data & generally die pretty promptly. Most notably this affects uniprocessor kernels running on any multicore or multithreaded Malta with a GIC (ie. the vast majority of real Malta boards). Fix this by only accessing up to min(gic_vpes, NR_CPUS) entries in the pcpu_masks array, preventing the array overrun.

2016-04-21net/mlx4_core: Don't allow to VF change global pause settingsEugenia Emantayev2-0/+15
Currently changing global pause settings is done via SET_PORT command with input modifier GENERAL. This command is allowed for each VF since MTU setting is done via the same command. Change the above to the following scheme: before passing the request to the FW, the PF will check whether it was issued by a slave. If yes, don't change global pause and warn, otherwise change to the requested value and store for further reference.

2016-04-21net: phy: spi_ks8895: Don't leak references to SPI devicesMark Brown1-1/+1
The ks8895 driver is using spi_dev_get() apparently just to take a copy of the SPI device used to instantiate it but never calls spi_dev_put() to free it. Since the device is guaranteed to exist between probe() and remove() there should be no need for the driver to take an extra reference to it so fix the leak by just using a straight assignment.
