driver core: platform: Don't read past the end of "driver_override" buffer
commit bf563b01c2895a4bfd1a29cc5abc67fe706ecffd upstream. When printing the driver_override parameter when it is 4095 and 4094 bytes long, the printing code would access invalid memory because we need count+1 bytes for printing. Reject driver_override values of these lengths in driver_override_store(). This is in close analogy to commit |

PM: core: Fix device_pm_check_callbacks()
commit 157c460e10cb6eca29ccbd0f023db159d0c55ec7 upstream.
The device_pm_check_callbacks() function doesn't check legacy
->suspend and ->resume callback pointers under the device's
bus type, class and driver, so in some cases it may set the
no_pm_callbacks flag for the device incorrectly and then the
callbacks may be skipped during system suspend/resume, which
shouldn't happen.
Fixes:

driver core: bus: Fix a potential double free
commit 0f9b011d3321ca1079c7a46c18cb1956fbdb7bcb upstream. The .release function of driver_ktype is 'driver_release()'. This function frees the container_of this kobject. So, this memory must not be freed explicitly in the error handling path of 'bus_add_driver()'. Otherwise a double free will occur.

The function to obtain a fwnode related to a struct device is useful for drivers that use the fwnode property API: it allows not being aware of the underlying firmware implementation.

PM / Domains: defer dev_pm_domain_set() until genpd->attach_dev succeeds if present
commit 975e83cfb8dc16e7a2fdc58188c77c0c605876c2 upstream.
If the genpd->attach_dev or genpd->power_on fails, genpd_dev_pm_attach
may return -EPROBE_DEFER initially. However genpd_alloc_dev_data sets
the PM domain for the device unconditionally.
When subsequent attempts are made to call genpd_dev_pm_attach, it may
return -EEXISTS checking dev->pm_domain without re-attempting to call
attach_dev or power_on.
platform_drv_probe then attempts to call drv->probe as the return value
-EEXIST != -EPROBE_DEFER, which may end up in a situation where the
device is accessed without it's power domain switched on.

PM / wakeirq: Convert to SRCU
commit ea0212f40c6bc0594c8eff79266759e3ecd4bacc upstream.
The wakeirq infrastructure uses RCU to protect the list of wakeirqs. That
breaks the irq bus locking infrastructure, which is allows sleeping
functions to be called so interrupt controllers behind slow busses,
e.g. i2c, can be handled.
The wakeirq functions hold rcu_read_lock and call into irq functions, which
in case of interrupts using the irq bus locking will trigger a
might_sleep() splat.
Convert the wakeirq infrastructure to Sleepable RCU and unbreak it.

PM / runtime: Avoid false-positive warnings from might_sleep_if()
[ Upstream commit a9306a63631493afc75893a4ac405d4e1cbae6aa ] The might_sleep_if() assertions in __pm_runtime_idle(), __pm_runtime_suspend() and __pm_runtime_resume() may generate false-positive warnings in some situations. For example, that happens if a nested pm_runtime_get_sync()/pm_runtime_put() pair is executed with disabled interrupts within an outer pm_runtime_get_sync()/pm_runtime_put() section for the same device. [Generally, pm_runtime_get_sync() may sleep, so it should not be called with disabled interrupts, but in this particular case the previous pm_runtime_get_sync() guarantees that the device will not be suspended, so the inner pm_runtime_get_sync() will return immediately after incrementing the device's usage counter.] That started to happen in the i915 driver in 4.10-rc, leading to the following splat: BUG: sleeping function called from invalid context at drivers/base/power/runtime.c:1032 in_atomic(): 1, irqs_disabled(): 0, pid: 1500, name: Xorg 1 lock held by Xorg/1500: #0: (&dev->struct_mutex){+.+.+.}, at: [<ffffffffa0680c13>] i915_mutex_lock_interruptible+0x43/0x140 [i915] CPU: 0 PID: 1500 Comm: Xorg Not tainted Call Trace: dump_stack+0x85/0xc2 ___might_sleep+0x196/0x260 __might_sleep+0x53/0xb0 __pm_runtime_resume+0x7a/0x90 intel_runtime_pm_get+0x25/0x90 [i915] aliasing_gtt_bind_vma+0xaa/0xf0 [i915] i915_vma_bind+0xaf/0x1e0 [i915] i915_gem_execbuffer_relocate_entry+0x513/0x6f0 [i915] i915_gem_execbuffer_relocate_vma.isra.34+0x188/0x250 [i915] ? trace_hardirqs_on+0xd/0x10 ? i915_gem_execbuffer_reserve_vma.isra.31+0x152/0x1f0 [i915] ? i915_gem_execbuffer_reserve.isra.32+0x372/0x3a0 [i915] i915_gem_do_execbuffer.isra.38+0xa70/0x1a40 [i915] ? __might_fault+0x4e/0xb0 i915_gem_execbuffer2+0xc5/0x260 [i915] ? __might_fault+0x4e/0xb0 drm_ioctl+0x206/0x450 [drm] ? i915_gem_execbuffer+0x340/0x340 [i915] ? __fget+0x5/0x200 do_vfs_ioctl+0x91/0x6f0 ? __fget+0x111/0x200 ? __fget+0x5/0x200 SyS_ioctl+0x79/0x90 entry_SYSCALL_64_fastpath+0x23/0xc6 even though the code triggering it is correct. Unfortunately, the might_sleep_if() assertions in question are too coarse-grained to cover such cases correctly, so make them a bit less sensitive in order to avoid the false-positives.

base/memory, hotplug: fix a kernel oops in show_valid_zones()
commit a96dfddbcc04336bbed50dc2b24823e45e09e80c upstream.
Reading a sysfs "memoryN/valid_zones" file leads to the following oops
when the first page of a range is not backed by struct page.
show_valid_zones() assumes that 'start_pfn' is always valid for
page_zone().
BUG: unable to handle kernel paging request at ffffea017a000000
IP: show_valid_zones+0x6f/0x160
This issue may happen on x86-64 systems with 64GiB or more memory since
their memory block size is bumped up to 2GiB. [1] An example of such
systems is desribed below. 0x3240000000 is only aligned by 1GiB and
this memory block starts from 0x3200000000, which is not backed by
struct page.
BIOS-e820: [mem 0x0000003240000000-0x000000603fffffff] usable
Since test_pages_in_a_zone() already checks holes, fix this issue by
extending this function to return 'valid_start' and 'valid_end' for a
given range. show_valid_zones() then proceeds with the valid range.

memory_hotplug: make zone_can_shift() return a boolean value
commit 8a1f780e7f28c7c1d640118242cf68d528c456cd upstream.
online_{kernel|movable} is used to change the memory zone to
ZONE_{NORMAL|MOVABLE} and online the memory.
To check that memory zone can be changed, zone_can_shift() is used.
Currently the function returns minus integer value, plus integer
value and 0. When the function returns minus or plus integer value,
it means that the memory zone can be changed to ZONE_{NORNAL|MOVABLE}.
But when the function returns 0, there are two meanings.
One of the meanings is that the memory zone does not need to be changed.
For example, when memory is in ZONE_NORMAL and onlined by online_kernel
the memory zone does not need to be changed.
Another meaning is that the memory zone cannot be changed. When memory
is in ZONE_NORMAL and onlined by online_movable, the memory zone may
not be changed to ZONE_MOVALBE due to memory online limitation(see
Documentation/memory-hotplug.txt). In this case, memory must not be
onlined.
The patch changes the return type of zone_can_shift() so that memory
online operation fails when memory zone cannot be changed as follows:
Before applying patch:
# grep -A 35 "Node 2" /proc/zoneinfo
Node 2, zone Normal
<snip>
node_scanned 0
spanned 8388608
present 7864320
managed 7864320
# echo online_movable > memory4097/state
# grep -A 35 "Node 2" /proc/zoneinfo
Node 2, zone Normal
<snip>
node_scanned 0
spanned 8388608
present 8388608
managed 8388608
online_movable operation succeeded. But memory is onlined as
ZONE_NORMAL, not ZONE_MOVABLE.
After applying patch:
# grep -A 35 "Node 2" /proc/zoneinfo
Node 2, zone Normal
<snip>
node_scanned 0
spanned 8388608
present 7864320
managed 7864320
# echo online_movable > memory4097/state
bash: echo: write error: Invalid argument
# grep -A 35 "Node 2" /proc/zoneinfo
Node 2, zone Normal
<snip>
node_scanned 0
spanned 8388608
present 7864320
managed 7864320
online_movable operation failed because of failure of changing
the memory zone from ZONE_NORMAL to ZONE_MOVABLE

PM / wakeirq: Fix dedicated wakeirq for drivers not using autosuspend
commit bed570307ed78f21b77cb04a1df781dee4a8f05a upstream.
I noticed some wakeirq flakeyness with consumer drivers not using
autosuspend. For drivers not using autosuspend, the wakeirq may never
get unmasked in rpm_suspend() because of irq desc->depth.
We are configuring dedicated wakeirqs to start with IRQ_NOAUTOEN as we
naturally don't want them running until rpm_suspend() is called.
However, when a consumer driver initially calls pm_runtime_get(), we
now wrongly start with disable_irq_nosync() call on the dedicated
wakeirq that is disabled to start with.
This causes desc->depth to toggle between 1 and 2 instead of the usual
0 and 1. This can prevent enable_irq() from unmasking the wakeirq as
that only happens at desc->depth 1.
This does not necessarily show up with drivers using autosuspend as
there is time for disable_irq_nosync() before rpm_suspend() gets called
after the autosuspend timeout.
Let's fix the issue by adding wirq->status that lazily gets set on
the first rpm_suspend(). We also need PM runtime core private functions
for dev_pm_enable_wake_irq_check() and dev_pm_disable_wake_irq_check()
so we can enable the dedicated wakeirq on the first rpm_suspend().
While at it, let's also fix the comments for dev_pm_enable_wake_irq()
and dev_pm_disable_wake_irq(). Those can still be used by the consumer
drivers as needed because the IRQ core manages the interrupt usecount
for us.

PM / OPP: Pass opp_table to dev_pm_opp_put_regulator()
commit 91291d9ad92faa65a56a9a19d658d8049b78d3d4 upstream. Joonyoung Shim reported an interesting problem on his ARM octa-core Odoroid-XU3 platform. During system suspend, dev_pm_opp_put_regulator() was failing for a struct device for which dev_pm_opp_set_regulator() is called earlier. This happened because an earlier call to dev_pm_opp_of_cpumask_remove_table() function (from cpufreq-dt.c file) removed all the entries from opp_table->dev_list apart from the last CPU device in the cpumask of CPUs sharing the OPP. But both dev_pm_opp_set_regulator() and dev_pm_opp_put_regulator() routines get CPU device for the first CPU in the cpumask. And so the OPP core failed to find the OPP table for the struct device. This patch attempts to fix this problem by returning a pointer to the opp_table from dev_pm_opp_set_regulator() and using that as the parameter to dev_pm_opp_put_regulator(). This ensures that the dev_pm_opp_put_regulator() doesn't fail to find the opp table. Note that similar design problem also exists with other dev_pm_opp_put_*() APIs, but those aren't used currently by anyone and so we don't need to update them for now.

PM / sleep: don't suspend parent when async child suspend_{noirq, late} fails
Consider two devices, A and B, where B is a child of A, and B utilizes asynchronous suspend (it does not matter whether A is sync or async). If B fails to suspend_noirq() or suspend_late(), or is interrupted by a wakeup (pm_wakeup_pending()), then it aborts and sets the async_error variable. However, device A does not (immediately) check the async_error variable; it may continue to run its own suspend_noirq()/suspend_late() callback. This is bad. We can resolve this problem by doing our error and wakeup checking (particularly, for the async_error flag) after waiting for children to suspend, instead of before. This also helps align the logic for the noirq and late suspend cases with the logic in __device_suspend(). It's easy to observe this erroneous behavior by, for example, forcing a device to sleep a bit in its suspend_noirq() (to ensure the parent is waiting for the child to complete), then return an error, and watch the parent suspend_noirq() still get called. (Or similarly, fake a wakeup event at the right (or is it wrong?) time.) Fixes: |

warn: variable dereferenced before check 'dev->bus' (see line 373)
Fix the warning by removing the dev->bus NULL check. dev->bus will never

Some drivers do not support removal/unbinding. These drivers should have
drv->suppress_bind_attrs set to true, so use that to skip the removal
test.
This doesn't fix anything reported so far, but should prevent some other
cases. Some drivers will need fixes to set suppress_bind_attrs to avoid
this test.

Pull ACPI updates from Rafael Wysocki:
"First off, the ACPICA code in the kernel is updated to upstream
revision 20160831 that brings in a few bug fixes and cleanups. In
particular, it is possible to mask GPEs now (and the sysfs interface
for GPE control is fixed on top of that), problems related to the
table loading mechanism are fixed and all code related to FADT version
2 (which has never been part of the ACPI specification) is dropped.
On the new features front, there is a new watchdog driver based on the
ACPI WDAT (ACPI Watchdog Action Table), needed on some platforms to
replace the iTCO watchdog that doesn't work there, and some UART
devices get new definitions of built-in properties (to be accessed via
the generic device properties API).
Also, included is a fix for an ACPI-related PCI resorces allocation
issue and a few problems in the EC driver and in the button and
battery drivers are fixed.
In addition to that, the ACPI CPPC library is updated to make batching
of requests sent over the PCC channel possible (which reduces the PCC
usage overhead substantially in some cases) and to support functional
fixed hardware (FFH) type of CPPC registers access (which will allow
CPPC to be used on x86 too in the future).
As usual, there are some assorted fixes and cleanups too.
Specifics:
- Update of the ACPICA code in the kernel to upstream revision
20160831 with the following major changes:
* New mechanism for GPE masking.
* Fixes for issues related to the LoadTable operator and table
loading.
* Fixes for issues related to so-called module-level code (MLC),
that is AML that doesn't belong to any methods.
* Change of the return value of the _OSI method to reflect the
Windows behavior.
* GAS (Generic Address Structure) support fix related to 32-bit
FADT addresses.
* Elimination of unnecessary FADT version 2 support.
* ACPI tools fixes and cleanups.
From Bob Moore, Lv Zheng, and Jung-uk Kim.
- ACPI sysfs interface updates to fix GPE handling (on top of the new
GPE masking mechanism in ACPICA) and issues related to table
loading (Lv Zheng).
- New watchdog driver based on the ACPI WDAT (ACPI Watchdog Action
Table), needed on some platforms to replace the iTCO watchdog that
doesn't work there and related updates of the intel_pmc_ipc,
i2c/i801 and MFD/lcp_ich drivers (Mika Westerberg).
- Driver core fix to prevent it from leaking secondary fwnode objects
during device removal (Lukas Wunner).
- New definitions of built-in properties for UART in ACPI-based x86
SoC drivers and a 8250_dw driver quirk for the APM X-Gene SoC

- Fix for a bug causing the allocation of PCI resorces to fail if
ACPI-enumerated child platform devices are registered below the PCI
devices in question (Mika Westerberg).
- Change of the default polarity for PCI legacy IRQs to high on

controller model fixing the discrepancy between the specification
and HW behavior (Lorenzo Pieralisi).
- Fixes for the handling of system suspend/resume in the ACPI EC
driver and update of that driver to make it cope with the cases
when the EC device defined in the ECDT has to be used throughout
the entire system life cycle (Lv Zheng).
- Update of the ACPI CPPC library to allow it to batch requests sent
