cifs: potential memory leaks when parsing mnt opts
For example, when mount opt is redundently specified

Althouhg mount.cifs in userspace performs a bit of sanitization

cifs: fix use-after-free bug in find_writable_file

sparc64: Fix several bugs in memmove().
Firstly, handle zero length calls properly. Believe it or not there
are a few of these happening during early boot.
Next, we can't just drop to a memcpy() call in the forward copy case
where dst <= src. The reason is that the cache initializing stores
used in the Niagara memcpy() implementations can end up clearing out
cache lines before we've sourced their original contents completely.
For example, considering NG4memcpy, the main unrolled loop begins like
this:
load src + 0x00
load src + 0x08
load src + 0x10
load src + 0x18
load src + 0x20
store dst + 0x00
Assume dst is 64 byte aligned and let's say that dst is src - 8 for
this memcpy() call. That store at the end there is the one to the
first line in the cache line, thus clearing the whole line, which thus
clobbers "src + 0x28" before it even gets loaded.
To avoid this, just fall through to a simple copy only mildly
optimized for the case where src and dst are 8 byte aligned and the
length is a multiple of 8 as well. We could get fancy and call
GENmemcpy() but this is good enough for how this thing is actually
used.

If ->run() fails, it can either free the data structures it

However:
md.c calls ->free() even if ->private_data is NULL, which
causes problems in some personalities.
raid0.c frees the data, but doesn't clear ->private_data,

Commit
db31c55a6fb2 (net: clamp ->msg_namelen instead of returning an

was larger than sizeof(struct sockaddr_storage). This caused a

====================
be2net: patch set
Hi David, this patch set includes 3 bug fixes to the be2net driver.
Patch 1 fixes a vlan isolation issue with VFs. When a VF is placed in
promiscous mode, it could receive packets belonging to any vlan, as
the PF driver grants vlan promisc capability to VFs. The PF
driver now disables the vlan promisc capability for VFs to fix this
problem.
Patch 2 fixes the call to MODIFY_EQ_DELAY FW cmd to not include more
than 8 EQs per cmd. The FW is not capable of handling more than 8 EQs
per cmd.
Patch 3 fixes an EEH error detection issue. On Power platforms,
when an EEH error occurs, the slot disconnect state is more reliably
detected via an MMIO read compared to a config read. So, the error
register reads that occur every second are now done via MMIO.
Pls apply this patch set to the "net" tree. Thanks!

When an EEH error occurs, the device/slot is disconnected. This condition

Hence, this patch fixes EEH error detection by replacing config reads with
MMIO reads for reading the error registers. The error registers in

arm64: efi: don't restore TTBR0 if active_mm points at init_mm
init_mm isn't a normal mm: it has swapper_pg_dir as its pgd (which
contains kernel mappings) and is used as the active_mm for the idle
thread.
When restoring the pgd after an EFI call, we write current->active_mm
into TTBR0. If the current task is actually the idle thread (e.g. when
initialising the EFI RTC before entering userspace), then the TLB can
erroneously populate itself with junk global entries as a result of
speculative table walks.
When we do eventually return to userspace, the task can end up hitting
these junk mappings leading to lockups, corruption or crashes.
This patch fixes the problem in the same way as the CPU suspend code by
ensuring that we never switch to the init_mm in efi_set_pgd and instead
point TTBR0 at the zero page. A check is also added to cpu_switch_mm to
BUG if we get passed swapper_pg_dir.

Revert "x86/PCI: Refine the way to release PCI IRQ resources"
Commit
b4b55cda5874 (Refine the way to release PCI IRQ resources)
introduced a regression in the PCI IRQ resource management by causing
the IRQ resource of a device, established when pci_enabled_device()
is called on a fully disabled device, to be released when the driver
is unbound from the device, regardless of the enable_cnt.
This leads to the situation that an ill-behaved driver can now make a
device unusable to subsequent drivers by an imbalance in their use of
pci_enable/disable_device(). That is a serious problem for secondary
drivers like vfio-pci, which are innocent of the transgressions of
the previous driver.
Since the solution of this problem is not immediate and requires
further discussion, revert commit
b4b55cda5874 and the issue it was
supposed to address (a bug related to xen-pciback) will be taken
care of in a different way going forward.

fuse: explicitly set /dev/fuse file's private_data
The misc subsystem (which is used for /dev/fuse) initializes private_data to
point to the misc device when a driver has registered a custom open file
operation, and initializes it to NULL when a custom open file operation has
*not* been provided.
This subtle quirk is confusing, to the point where kernel code registers
*empty* file open operations to have private_data point to the misc device
structure. And it leads to bugs, where the addition or removal of a custom open
file operation surprisingly changes the initial contents of a file's
private_data structure.
So to simplify things in the misc subsystem, a patch [1] has been proposed to
*always* set the private_data to point to the misc device, instead of only
doing this when a custom open file operation has been registered.
But before this patch can be applied we need to modify drivers that make the
assumption that a misc device file's private_data is initialized to NULL
because they didn't register a custom open file operation, so they don't rely
on this assumption anymore. FUSE uses private_data to store the fuse_conn and
errors out if this is not initialized to NULL at mount time.
Hence, we now set a file's private_data to NULL explicitly, to be independent
of whatever value the misc subsystem initializes it to by default.

of: handle both '/' and ':' in path strings
Commit
106937e8ccdc ("of: fix handling of '/' in options for
of_find_node_by_path()") caused a regression in OF handling of
stdout-path. While it fixes some cases which have '/' after the ':', it
breaks cases where there is more than one '/' *before* the ':'.
For example, it breaks this boot string
stdout-path = "/rdb/serial@
f040ab00:115200";
So rather than doing sequentialized checks (first for '/', then for ':';
or vice versa), to get the correct behavior we need to check for the
first occurrence of either one of them.
It so happens that the handy strcspn() helper can do just that.

netfilter: restore rule tracing via nfnetlink_log
Since

This is a problem for people tracing rules through nfnetlink_log since
packets are always routed to the NF_LOG_TYPE logger after the
aforementioned patch.
We can fix this by removing the trace loginfo structures, but that still
changes the log level from 4 to 5 for tracing messages and there may be

Merge branch 'exynos-drm-fixes' of git://git./linux/kernel/git/daeinki/drm-exynos into drm-fixes
Some urgent regression fixes to booting failures Exynos DRM occured.
Summary:
- Fix two urgent null pointer dereference bugs in case of enabling
or disabling IOMMU. There was two cases to these issues.
One is that plane->crtc is accessed by exynos_disable_plane()
when device tree binding is broken so device driver tries
to release, which means that the mode set operation isn't invoked yet
so plane->crtc is still NULL and exynos_disable_plane() will access
NULL pointer. This issue is fixed by checking if the plane->crtc
is NULL or not in exynos_disable_plane()
Other is that fimd_wait_for_vblank() is called to avoid from page fault
with IOMMU before the ctx object is created. At this time,
fimd_wait_for_vblank() tries to access ctx->crtc but the ctx->crtc
is still NULL because exynos_drm_crtc_create() isn't called yet.
This issue is fixed by creating a crtc object and setting it to
ctx->crtc prior to fimd_wait_for_vblank() call.
For more details, you can refer to below an e-mail thread,
http://www.spinics.net/lists/linux-samsung-soc/msg42436.html

IB/mlx4: Saturate RoCE port PMA counters in case of overflow
For RoCE ports, we set the u32 PMA values based on u64 HCA counters. In case of
overflow, according to the IB spec, we have to saturate a counter to its
max value, do that.

drm/radeon: drop ttm two ended allocation
radeon_bo_create() calls radeon_ttm_placement_from_domain()
before ttm_bo_init() is called. radeon_ttm_placement_from_domain()
uses the ttm bo size to determine when to select top down
allocation but since the ttm bo is not initialized yet the
check is always false. It only took effect when buffers
were validated later. It also seemed to regress suspend
and resume on some systems possibly due to it not
taking effect in radeon_bo_create().
radeon_bo_create() and radeon_ttm_placement_from_domain()
need to be reworked substantially for this to be optimally
effective. Re-enable it at that point.

USB: ehci-atmel: rework clk handling
The EHCI IP only needs the UTMI/UPLL (uclk) and the peripheral (iclk)
clocks to work properly. Remove the useless system clock (fclk).
Avoid calling set_rate on the fixed rate UTMI/IPLL clock and remove
useless IS_ENABLED(CONFIG_COMMON_CLK) tests (all at91 platforms have been
moved to the CCF).
This patch also fixes a bug introduced by
3440ef1 (ARM: at91/dt: fix USB
high-speed clock to select UTMI), which was leaving the usb clock
uninitialized and preventing the OHCI driver from setting the usb clock
rate to 48MHz.
This bug was caused by several things:
1/ usb clock drivers set the CLK_SET_RATE_GATE flag, which means the rate
cannot be changed once the clock is prepared
2/ The EHCI driver was retrieving and preparing/enabling the uhpck
clock which was in turn preparing its parent clock (the usb clock),
thus preventing any rate change because of 1/
