From b42db0860e13067fcc7cbfba3966c9e652668bbc Mon Sep 17 00:00:00 2001
From: Eric Sandeen <sandeen@sandeen.net>
Date: Mon, 16 Apr 2018 23:06:53 -0700
Subject: [PATCH] xfs: enhance dinode verifier
Add several more validations to xfs_dinode_verify:
- For LOCAL data fork formats, di_nextents must be 0.
- For LOCAL attr fork formats, di_anextents must be 0.
- For inodes with no attr fork offset,
- format must be XFS_DINODE_FMT_EXTENTS if set at all
- di_anextents must be 0.
Thanks to dchinner for pointing out a couple related checks I had
forgotten to add.

Subject: [PATCH] xfs: set format back to extents if xfs_bmap_extents_to_btree
If xfs_bmap_extents_to_btree fails in a mode where we call
xfs_iroot_realloc(-1) to de-allocate the root, set the
format back to extents.
Otherwise we can assume we can dereference ifp->if_broot
based on the XFS_DINODE_FMT_BTREE format, and crash.

Update the features after calling register_netdev() otherwise the
device features are not set up correctly and it not possible to change
the MTU of the device. After this change, the features reported by
ethtool match the device's features before the commit which introduced
the issue and it is possible to change the device's MTU.

Subject: [v2,1/2] arm64: fpsimd: Split cpu field out from struct fpsimd_state
From: Dave P Martin <Dave.Martin@arm.com>

In preparation for using a common representation of the FPSIMD
state for tasks and KVM vcpus, this patch separates out the "cpu"
field that is used to track the cpu on which the state was most
recently loaded.
This will allow common code to operate on task and vcpu contexts
without requiring the cpu field to be stored at the same offset
from the FPSIMD register data in both cases. This should avoid the
need for messing with the definition of those parts of struct
vcpu_arch that are exposed in the KVM user ABI.
The resulting change is also convenient for grouping and defining
the set of thread_struct fields that are supposed to be accessible
to copy_{to,from}_user(), which includes user_fpsimd_state but
should exclude the cpu field. This patch does not amend the
usercopy whitelist to match: that will be addressed in a subsequent
patch.

Subject: [v2,2/2] arm64: uaccess: Fix omissions from usercopy whitelist
From: Dave P Martin <Dave.Martin@arm.com>
X-Patchwork-Id: 10312691
Message-Id: <1522230649-22008-3-git-send-email-Dave.Martin@arm.com>

When the hardend usercopy support was added for arm64, it was
concluded that all cases of usercopy into and out of thread_struct
were statically sized and so didn't require explicit whitelisting
of the appropriate fields in thread_struct.
Testing with usercopy hardening enabled has revealed that this is
not the case for certain ptrace regset manipulation calls on arm64.
This occurs because the sizes of usercopies associated with the
regset API are dynamic by construction, and because arm64 does not
always stage such copies via the stack: indeed the regset API is
designed to avoid the need for that by adding some bounds checking.
This is currently believed to affect only the fpsimd and TLS
registers.
Because the whitelisted fields in thread_struct must be contiguous,
this patch groups them together in a nested struct. It is also
necessary to be able to determine the location and size of that
struct, so rather than making the struct anonymous (which would
save on edits elsewhere) or adding an anonymous union containing
named and unnamed instances of the same struct (gross), this patch
gives the struct a name and makes the necessary edits to code that
references it (noisy but simple).
Care is needed to ensure that the new struct does not contain
padding (which the usercopy hardening would fail to protect).
For this reason, the presence of tp2_value is made unconditional,
since a padding field would be needed there in any case. This pads
up to the 16-byte alignment required by struct user_fpsimd_state.

Changes since v1:
* Add a BUILD_BUG_ON() check for padding in the whitelist struct.
* Move to using sizeof_field() for assigning *size; get rid of the
dummy pointer that was used previously.
* Delete bogus comment about why no whitelist is (was) needed.

+Raspberry Pi GPIO expander
+
+The Raspberry Pi 3 GPIO expander is controlled by the VC4 firmware. The
+firmware exposes a mailbox interface that allows the ARM core to control the
+GPIO lines on the expander.
+
+The Raspberry Pi GPIO expander node must be a child node of the Raspberry Pi
+firmware node.
+
+Required properties:
+
+- compatible : Should be "raspberrypi,firmware-gpio"
+- gpio-controller : Marks the device node as a gpio controller
+- #gpio-cells : Should be two. The first cell is the pin number, and
+ the second cell is used to specify the gpio polarity:
+ 0 = active high
+ 1 = active low
+
+Example:
+
+firmware: firmware-rpi {
+ compatible = "raspberrypi,bcm2835-firmware";
+ mboxes = <&mailbox>;
+
+ expgpio: gpio {
+ compatible = "raspberrypi,firmware-gpio";
+ gpio-controller;
+ #gpio-cells = <2>;
+ };

Subject: gpio: raspberrypi-exp: Driver for RPi3 GPIO expander via mailbox
service
Pi3 and Compute Module 3 have a GPIO expander that the
VPU communicates with.
There is a mailbox service that now allows control of this
expander, so add a kernel driver that can make use of it.

Subject: [PATCH 3/9] lan78xx: Avoid spurious kevent 4 "error"
lan78xx_defer_event generates an error message whenever the work item
is already scheduled. lan78xx_open defers three events -
EVENT_STAT_UPDATE, EVENT_DEV_OPEN and EVENT_LINK_RESET. Being aware
of the likelihood (or certainty) of an error message, the DEV_OPEN
event is added to the set of pending events directly, relying on
the subsequent deferral of the EVENT_LINK_RESET call to schedule the
work. Take the same precaution with EVENT_STAT_UPDATE to avoid a
totally unnecessary error message.

Subject: [PATCH 4/9] lan78xx: Don't reset the interface on open
Commit 92571a1aae40 ("lan78xx: Connect phy early") moves the PHY
initialisation into lan78xx_probe, but lan78xx_open subsequently calls
lan78xx_reset. As well as forcing a second round of link negotiation,
this reset frequently prevents the phy interrupt from being generated
(even though the link is up), rendering the interface unusable.
Fix this issue by removing the lan78xx_reset call from lan78xx_open.

Since 517e7a1537a ("ASoC: bcm2835: move to use the clock framework")
the bcm2835-i2s requires a clock as DT property. Unfortunately
the necessary DT change has never been applied. While we are at it
also fix the first PCM register range to cover the PCM_GRAY register.
This patch only fixes the affected dt-bindings.

USB devices use the DMA mask and offset of the controller, which have
already been setup when a device is probed. Note that modifying the
DMA mask of a USB device would change the mask for the controller (and
all devices on the bus) as the mask is literally shared.
Since commit 2bf698671205 ("USB: of: fix root-hub device-tree node
handling"), of_dma_configure() would be called also for root hubs, which
use the device node of the controller. A separate, long-standing bug
that makes of_dma_configure() generate a 30-bit DMA mask from the RPI3's
"dma-ranges" would thus set a broken mask also for the controller. This
in turn prevents USB devices from enumerating when control transfers
fail:
dwc2 3f980000.usb: Cannot do DMA to address 0x000000003a166a00
Note that the aforementioned DMA-mask bug was benign for the HCD itself
as the dwc2 driver overwrites the mask previously set by
of_dma_configure() for the platform device in its probe callback. The
mask would only later get corrupted when the root-hub child device was
probed.
Fix this, and similar future problems, by adding a flag to struct device
which prevents driver core from calling dma_configure() during probe and
making sure it is set for USB devices.
Fixes: 09515ef5ddad ("of/acpi: Configure dma operations at probe time for platform/amba/pci bus devices")

v3
- add flag to struct device to prevent DMA configuration during probe instead
of checking for the USB bus type, which is not available when USB is built
as a module as noted by Alan
- drop moderated rpi list from CC
v2
- amend commit message and point out that the long-standing 30-bit DMA-mask
bug was benign to the dwc2 HCD itself (Robin)
- add and use a new dev_is_usb() helper (Robin)
