commit 8b57b9669aa884ac75b8d09c251d6b1755533c15 upstream.
Commit 3fdfedaaa "[media] omap3isp: preview: Lower the crop margins"
accidentally changed the previewer's cropping, causing the previewer
to miss four pixels on each line, thus corrupting the final image.
Restored the removed setting.

commit 30d652823de5fd7907d40e969a2d8e23938d8d03 upstream.
Do not attempt to reload the tuner modules when resuming after a suspend.
This triggers a WARN_ON in kernel/kmod.c:148 __request_module.
This fixes https://bugzilla.kernel.org/show_bug.cgi?id=69581.
This has always been wrong, but it was never noticed until the WARN_ON
was added in 3.9.

commit 3ec40dcfb413214b2874aec858870502b61c2202 upstream.
Pointer to device state has been moved to different location during
some change. PCTV 290e LNA function still uses old pointer, carried
over FE priv, and it crash.

commit 8272d0a0c0d374a01721e579df6e8add5577132b upstream.
Add m88rs2000_get_tune_settings, min delay of 2000 ms on symbol
rate more than 3000000 and delay of 3000ms less than this.
Adding min delay prevents crashing the frontend on continuous
transponder scans. Other dvb_frontend_tune_settings remain as default.
This makes very little time difference to good channel scans, but slows down
the set frontend where lock can never be achieved i.e. DVB-S2.

commit b1e43f232698274871e1358c276d7b0242a7d607 upstream.
The UVC specification uses alternate setting selection to notify devices
of stream start/stop. This breaks when using bulk-based devices, as the
video streaming interface has a single alternate setting in that case,
making video stream start and video stream stop events to appear
identical to the device. Bulk-based devices are thus not well supported
by UVC.
The webcam built in the Asus Zenbook UX302LA ignores the set interface
request and will keep the video stream enabled when the driver tries to
stop it. If USB autosuspend is enabled the device will then be suspended
and will crash, requiring a cold reboot.
USB trace capture showed that Windows sends a CLEAR_FEATURE(HALT)
request to the bulk endpoint when stopping the stream instead of
selecting alternate setting 0. The camera then behaves correctly, and
thus seems to require that behaviour.
Replace selection of alternate setting 0 with clearing of the endpoint
halt feature at video stream stop for bulk-based devices. Let's refrain
from blaming Microsoft this time, as it's not clear whether this
Windows-specific but USB-compliant behaviour was specifically developed
to handle bulkd-based UVC devices, or if the camera just took advantage
of it.

commit 01bb59ebffdec314da8da66266edf29529372f9b upstream.
When CONFIG_PCI and CONFIG_PM are not selected, xhci.c gets this
warning:
drivers/usb/host/xhci.c:409:13: warning: ‘xhci_msix_sync_irqs’ defined
but not used [-Wunused-function]
Instead of creating nested #ifdefs, this patch fixes it by defining the
xHCI PCI stubs as inline.
This warning has been in since 3.2 kernel and was
caused by commit 421aa841a134f6a743111cf44d0c6d3b45e3cf8c
"usb/xhci: hide MSI code behind PCI bars", but wasn't noticed

commit bcffae7708eb8352f44dc510b326541fe43a02a4 upstream.
xHCI driver has its own pci probe function that will call usb_hcd_pci_probe
to register its usb-2 bus, and then continue to manually register the
usb-3 bus. usb_hcd_pci_probe does a pm_runtime_put_noidle at the end and
might thus trigger a runtime suspend before the usb-3 bus is ready.
Prevent the runtime suspend by increasing the usage count in the
beginning of xhci_pci_probe, and decrease it once the usb-3 bus is
ready.
xhci-platform driver is not using usb_hcd_pci_probe to set up
busses and should not need to have it's usage count increased during probe.

commit 9c1b70361e0b38e4acb8e62b54da66538cb77ff2 upstream.
It was impossible to enumerate on a SuperSpeed (XHCI) host
with alternate setting = 1 due to the wrongly set 'bMaxBurst'
field in the SuperSpeed Endpoint Companion descriptor.
Testcase:
<host> modprobe -r usbtest; modprobe usbtest alt=1
<device> modprobe g_zero
plug device to SuperSpeed port on the host.
Without this patch the host always complains like so
"usb 12-2: Not enough bandwidth for new device state.
usb 12-2: Not enough bandwidth for altsetting 1"

commit 7e8213c1f3acc064aef37813a39f13cbfe7c3ce7 upstream.
code32_start should point at the start of the protected mode code, and
*not* at the beginning of the bzImage. This is much easier to do in
assembly so document that callers of make_boot_params() need to fill out
code32_start.
The fallout from this bug is that we would end up relocating the image
but copying the image at some offset, resulting in what appeared to be
memory corruption.

commit 2c42be2dd4f6586728dba5c4e197afd5cfaded78 upstream.
ft_del_tpg checks tpg->tport is set before unlinking the tpg from the
tport when the tpg is being removed. Set this pointer in ft_tport_create,
or the unlinking won't happen in ft_del_tpg and tport->tpg will reference
a deleted object.
This patch sets tpg->tport in ft_tport_create, because that's what
ft_del_tpg checks, and is the only way to get back to the tport to
clear tport->tpg.
The bug was occuring when:
- lport created, tport (our per-lport, per-provider context) is
allocated.
tport->tpg = NULL
- tpg created
- a PRLI is received. ft_tport_create is called, tpg is found and
tport->tpg is set
- tpg removed. ft_tpg is freed in ft_del_tpg. Since tpg->tport was not
set, tport->tpg is not cleared and points at freed memory
- Future calls to ft_tport_create return tport via first conditional,
instead of searching for new tpg by calling ft_lport_find_tpg.
tport->tpg is still invalid, and will access freed memory.

commit d444edc679e7713412f243b792b1f964e5cff1e1 upstream.
This patch fixes a long-standing bug in iscsit_build_conn_drop_async_message()

end up being used to send the ISCSI_OP_ASYNC_EVENT + DROPPING_CONNECTION

The bug was manifesting itself as an OOPs in iscsit_allocate_cmd() with
a bogus conn_p pointer in iscsit_build_conn_drop_async_message().

commit b2a72ec32d0f499aaadf41264232517a12326df0 upstream.
qla2x00_mem_alloc() returns 1 on success and -ENOMEM on failure. On the
one hand the caller assumes non-zero is success but on the other hand
the caller also assumes that it returns an error code.
I've fixed it to return zero on success and a negative error code on
failure. This matches the documentation as well.

commit b076808051f2c80d38e03fb2f1294f525c7a446d upstream.
The code was incorrectly using sg_dma_address() and
sg_dma_len() instead of ib_sg_dma_address() and
ib_sg_dma_len().
This prevents srpt from functioning with the
Intel HCA and indeed will corrupt memory
badly.

commit 9d194d1025f463392feafa26ff8c2d8247f71be1 upstream.
In case of error while accessing to userspace memory, function
nes_create_qp() returns NULL instead of an error code wrapped through
ERR_PTR(). But NULL is not expected by ib_uverbs_create_qp(), as it
check for error with IS_ERR().
As page 0 is likely not mapped, it is going to trigger an Oops when
the kernel will try to dereference NULL pointer to access to struct
ib_qp's fields.
In some rare cases, page 0 could be mapped by userspace, which could
turn this bug to a vulnerability that could be exploited: the function
pointers in struct ib_device will be under userspace total control.
This was caught when using spatch (aka. coccinelle)
to rewrite calls to ib_copy_{from,to}_udata().

commit a2cb0eb8a64adb29a99fd864013de957028f36ae upstream.
Guard against a potential buffer overrun. The size to read from the
user is passed in, and due to the padding that needs to be taken into
account, as well as the place holder for the ICRC it is possible to
overflow the 32bit value which would cause more data to be copied from
user space than is allocated in the buffer.

commit 3064639423c48d6e0eb9ecc27c512a58e38c6c57 upstream.
There could be a case, when NFSd file system is mounted in network, different
to socket's one, like below:
"ip netns exec" creates new network and mount namespace, which duplicates NFSd
mount point, created in init_net context. And thus NFS server stop in nested
network context leads to RPCBIND client destruction in init_net.
Then, on NFSd start in nested network context, rpc.nfsd process creates socket
in nested net and passes it into "write_ports", which leads to RPCBIND sockets
creation in init_net context because of the same reason (NFSd monut point was
created in init_net context). An attempt to register passed socket in nested
net leads to panic, because no RPCBIND client present in nexted network
namespace.
This patch add check that passed socket's net matches NFSd superblock's one.
And returns -EINVAL error to user psace otherwise.
v2: Put socket on exit.

commit 2076a20fc1a06f7b0333c62a2bb4eeeac7ed1bcb upstream.
Ensure that querying the IIO buffer scan_mask returns a value of
0 or 1. Currently querying the scan mask has the value returned
by test_bit(), which returns either true or false. For some
architectures test_bit() may return -1 for true, which will appear
to return an error when returning from iio_scan_mask_query().
Additionally, it's important for the sysfs interface to consistently
return the same thing when querying the scan_mask.

commit a2ff864b53eac9a0e9b05bfe9d1781ccd6c2af71 upstream.
The code in hcd-pci.c that matches up EHCI controllers with their
companion UHCI or OHCI controllers assumes that the private drvdata
fields don't get set too early. However, it turns out that this field
gets set by usb_create_hcd(), before hcd-pci expects it, and this can
result in a crash when two controllers are probed in parallel (as can
happen when a new controller card is hotplugged).
The companions_rwsem lock was supposed to prevent this sort of thing,
but usb_create_hcd() is called outside the scope of the rwsem.
A simple solution is to check that the root-hub pointer has been
initialized as well as the drvdata field. This doesn't happen until
usb_add_hcd() is called; that call and the check are both protected by
the rwsem.
This patch should be applied to stable kernels from 3.10 onward.

commit b3b42ac2cbae1f3cecbb6229964a4d48af31d382 upstream.
The IRET instruction, when returning to a 16-bit segment, only
restores the bottom 16 bits of the user space stack pointer. We have
a software workaround for that ("espfix") for the 32-bit kernel, but
it relies on a nonzero stack segment base which is not available in
32-bit mode.
Since 16-bit support is somewhat crippled anyway on a 64-bit kernel
(no V86 mode), and most (if not quite all) 64-bit processors support
virtualization for the users who really need it, simply reject
attempts at creating a 16-bit segment when running on top of a 64-bit
kernel.

commit 12729f14d8357fb845d75155228b21e76360272d upstream.
If a failure occurs while modifying ftrace function, it bails out and will
remove the tracepoints to be back to what the code originally was.
There is missing the final sync run across the CPUs after the fix up is done
and before the ftrace int3 handler flag is reset.
Here's the description of the problem:

commit c88547a8119e3b581318ab65e9b72f27f23e641d upstream.
Commit f5ea1100 ("xfs: add CRCs to dir2/da node blocks") introduced
in 3.10 incorrectly converted the btree hash index array pointer in
xfs_da3_fixhashpath(). It resulted in the the current hash always
being compared against the first entry in the btree rather than the
current block index into the btree block's hash entry array. As a
result, it was comparing the wrong hashes, and so could misorder the
entries in the btree.
For most cases, this doesn't cause any problems as it requires hash
collisions to expose the ordering problem. However, when there are
hash collisions within a directory there is a very good probability
that the entries will be ordered incorrectly and that actually
matters when duplicate hashes are placed into or removed from the
btree block hash entry array.
This bug results in an on-disk directory corruption and that results
in directory verifier functions throwing corruption warnings into
the logs. While no data or directory entries are lost, access to
them may be compromised, and attempts to remove entries from a
directory that has suffered from this corruption may result in a
filesystem shutdown. xfs_repair will fix the directory hash
ordering without data loss occuring.

commit 6b355b33a64fd6d8ead2b838ec16fb9b551f71e8 upstream.
Previous logic,
if (avail > 8) {
store slave;
return;
}
send data; clear;
The logic error is, if there isn't space send the buffer and clear,
but the slave wasn't added to the now empty buffer loosing that slave
id. It also should have been "if (avail >= 8)" because when it is 8,
there is space.
Instead, if there isn't space send and clear the buffer, then there is
always space for the slave id.

regmap_add_irq_chip fail
commit 483e2dfdbc94751430e41db9973985f5b054d322 upstream.
Fixes: 4aab3fadad32 ("mfd: tps65910: Move interrupt implementation code to mfd file")
tps65910_irq_init() sets 'tps65910->chip_irq' before calling
regmap_add_irq_chip(). If the regmap_add_irq_chip() call fails in
memory allocation of regmap_irq_chip_data members then:
1. The 'tps65910->chip_irq' will still hold some value
2. 'tps65910->irq_data' will be pointing to already freed memory
(because regmap_add_irq_chip() will free it on error)
This results in invalid memory access during driver remove because the
tps65910_irq_exit() tests whether 'tps65910->chip_irq' is not zero.

main MFD driver.

commit 65aba1e04916d72b30c028730a1e31860c225412 upstream.
During probe the sec-core driver allocates dummy I2C device for RTC with
i2c_new_dummy() but return value is not checked. In case of error
(i2c_new_device(): memory allocation failure or I2C address cannot be
used) this function returns NULL which is later used by
devm_regmap_init_i2c() or i2c_unregister_device().
If i2c_new_dummy() fails for RTC device, fail also the probe for main
MFD driver.

commit 5e6533a6f52f1a8283b2f818f5828be99a417dd6 upstream.
NM and SPS FW types that may run on ME device on server platforms
do not have valid MEI/HECI interface and driver should not
be bound to it as this might lead to system hung.
In practice not all BIOSes effectively hide such devices from the
OS and in some cases it is not possible.
We determine FW type by examining Host FW status registers in order to
unbind the driver.
In this patch we are adding check for ME on Cougar Point, Lynx Point

commit 2253e8d79237c69086ded391e6767afe16972527 upstream.
ccw consoles are in use before they can be properly registered with
the driver core. For devices which are in use by a device driver we
rely on the ccw_device's pointer to the driver callbacks to be valid.
For ccw consoles this pointer is NULL until they are registered later
during boot and we dereferenced this pointer. This worked by
chance on 64 bit builds (cdev->drv was NULL but the optional callback
cdev->drv->path_event was also NULL by coincidence) and was unnoticed
until we received reports about boot failures on 31 bit systems.
Fix it by initializing the driver pointer for ccw consoles.
