"Block fixes for 4.19-rc6
A set of fixes that should go into this release. This pull request
contains:
- A fix (hopefully) for the persistent grants for xen-blkfront. A
previous fix from this series wasn't complete, hence reverted, and
this one should hopefully be it. (Boris Ostrovsky)
- Fix for an elevator drain warning with SMR devices, which is
triggered when you switch schedulers (Damien)
- bcache deadlock fix (Guoju Fang)
- Fix for the block unplug tracepoint, which has had the
timer/explicit flag reverted since 4.11 (Ilya)

invoked with the RCU read lock held, hence preventing it from

cpufreq: qcom-kryo: Fix section annotations
|
|
There is currently a warning when building the Kryo cpufreq driver into
the kernel image:
WARNING: vmlinux.o(.text+0x8aa424): Section mismatch in reference from
the function qcom_cpufreq_kryo_probe() to the function
.init.text:qcom_cpufreq_kryo_get_msm_id()
The function qcom_cpufreq_kryo_probe() references
the function __init qcom_cpufreq_kryo_get_msm_id().
This is often because qcom_cpufreq_kryo_probe lacks a __init
annotation or the annotation of qcom_cpufreq_kryo_get_msm_id is wrong.
Remove the '__init' annotation from qcom_cpufreq_kryo_get_msm_id
so that there is no more mismatch warning.
Additionally, Nick noticed that the remove function was marked as
'__init' when it should really be marked as '__exit'.

After write SSD completed, bcache schedules journal_write work to
system_wq, which is a public workqueue in system, without WQ_MEM_RECLAIM
flag. system_wq is also a bound wq, and there may be no idle kworker on
current processor. Creating a new kworker may unfortunately need to
reclaim memory first, by shrinking cache and slab used by vfs, which
depends on bcache device. That's a deadlock.
This patch create a new workqueue for journal_write with WQ_MEM_RECLAIM
flag. It's rescuer thread will work to avoid the deadlock.

[Why]
EDID emulation didn't work properly for linux, as we stop programming
if nothing is connected physically.
[How]
We get a flag from DRM when we want to do edid emulation. We check if
this flag is true and nothing is connected physically, if so we only
program the front end using VIRTUAL_SIGNAL.

[Why]
There have been a few reports of Vega10 display remaining blank
after S3 resume. The regression is caused by workaround for mode
change on Vega10 - skip set_bandwidth if stream count is 0.
As a result we skipped dispclk reset on suspend, thus on resume
we may skip the clock update assuming it hasn't been changed.
On some systems it causes display blank or 'out of range'.
[How]
Revert "drm/amd/display: Fix Vega10 black screen after mode change"
Verified that it hadn't cause mode change regression.

The vce cancel_delayed_work_sync never be called.

This caused the A+A suspend hang when runtime pm enebled.
As we will visit the smu in the idle queue. this will cause
smu hang because the dgpu has been suspend, and the dgpu also
will be waked up. As the smu has been hang, so the dgpu resume
will failed.

This reverts commit 0c08754b59da5557532d946599854e6df28edc22.
commit 0c08754b59da
("drm/panel: Add device_link from panel device to DRM device")
creates a circular dependency under these circumstances:
1. The panel depends on dsi-host because it is MIPI-DSI child
device.
2. dsi-host depends on the drm parent device (connector->dev->dev)
this should be allowed.
3. drm parent dev (connector->dev->dev) depends on the panel
after this patch.
This makes the dependency circular and while it appears it
does not affect any in-tree drivers (they do not seem to have
dsi hosts depending on the same parent device) this does not
seem right.
As noted in a response from Andrzej Hajda, the intent is
likely to make the panel dependent on the DRM device
(connector->dev) not its parent. But we have no way of
doing that since the DRM device doesn't contain any
struct device on its own (arguably it should).
Revert this until a proper approach is figured out.

Commit a46b53672b2c ("xen/blkfront: cleanup stale persistent grants")
added support for purging persistent grants when they are not in use. As
part of the purge, the grants were removed from the grant buffer, This
eventually causes the buffer to become empty, with BUG_ON triggered in
get_free_grant(). This can be observed even on an idle system, within
20-30 minutes.
We should keep the grants in the buffer when purging, and only free the
grant ref.

HP 6730b laptop has an ethernet NIC connected to one of the PCIe root
ports. The root ports themselves are native PCIe hotplug capable. Now,
during boot after PCI devices are scanned the BIOS triggers ACPI bus check
directly to the NIC:
ACPI: \_SB_.PCI0.RP06.NIC_: Bus check in hotplug_event()
It is not clear why it is sending bus check but regardless the ACPI hotplug
notify handler calls enable_slot() directly (instead of going through
acpiphp_check_bridge() as there is no bridge), which ends up handling
special case for non-hotplug bridges with native PCIe hotplug. This
results a crash of some kind but the reporter only sees black screen so it
is hard to figure out the exact spot and what actually happens. Based on
a few fix proposals it was tracked to crash somewhere inside
pci_assign_unassigned_bridge_resources().
In any case we should not really be in that special branch at all because
the ACPI notify happened to a slot that is not a PCI bridge (it is just a
regular PCI device).
Fix this so that we only go to that special branch if we are calling
enable_slot() for a bridge (e.g., the ACPI notification was for the
bridge).

OMAPFB_MEMORY_READ ioctl reads pixels from the LCD's memory and copies
them to a userspace buffer. The code has two issues:
- The user provided width and height could be large enough to overflow
the calculations
- The copy_to_user() can copy uninitialized memory to the userspace,
which might contain sensitive kernel information.
Fix these by limiting the width & height parameters, and only copying
the amount of data that we actually received from the LCD.

We attempt to get fences earlier in the hopes that everything will
already have fences and no callbacks will be needed. If we do succeed
in getting a fence, getting one a second time will result in a duplicate
ref with no unref. This is causing memory leaks in Vulkan applications
that create a lot of fences; playing for a few hours can, apparently,
bring down the system.

"IOMMU Fixes for Linux v4.19-rc5
Three fixes queued up:
- Warning fix for Rockchip IOMMU where there were IRQ handlers
for offlined hardware.
- Fix for Intel VT-d because recent changes caused boot failures
on some machines because it tried to allocate to much
contiguous memory.
- Fix for AMD IOMMU to handle eMMC devices correctly that appear
as ACPI HID devices."

ACPI HID devices do not actually have an alias for
them in the IVRS. But dev_data->alias is still used
for indexing into the IOMMU device table for devices
being handled by the IOMMU. So for ACPI HID devices,
we simply return the corresponding devid as an alias,
as parsed from IVRS table.

Currently add_modify_gid() for IB link layer has followong issue
in cache update path.
When GID update event occurs, core releases reference to the GID
table without updating its state and/or entry pointer.
CPU-0 CPU-1
------ -----
ib_cache_update() IPoIB ULP
add_modify_gid() [..]
put_gid_entry()
refcnt = 0, but
state = valid,
entry is valid.
(work item is not yet executed).
ipoib_create_ah()
rdma_create_ah()
rdma_get_gid_attr() <--
Tries to acquire gid_attr
which has refcnt = 0.
This is incorrect.
GID entry state and entry pointer is provides the accurate GID enty
state. Such fields must be updated with rwlock to protect against
readers and, such fields must be in sane state before refcount can drop
to zero. Otherwise above race condition can happen leading to
use-after-free situation.
Following backtrace has been observed when cache update for an IB port
is triggered while IPoIB ULP is creating an AH.
Therefore, when updating GID entry, first mark a valid entry as invalid
through state and set the barrier so that no callers can acquired
the GID entry, followed by release reference to it.
refcount_t: increment on 0; use-after-free.
