If the sector number is too high, dm_table_find_target() should return a
pointer to a zeroed dm_target structure (the caller should test it with
dm_target_is_valid).
However, for some table sizes, the code in dm_table_find_target() that
performs btree lookup will access out of bound memory structures.
Fix this bug by testing the sector number at the beginning of
dm_table_find_target(). Also, add an "inline" keyword to the function
dm_table_get_size() because this is a hot path.

In commit 6096d91af0b6 ("dm space map metadata: fix occasional leak
of a metadata block on resize"), we refactor the commit logic to a new
function 'apply_bops'. But when that logic was replaced in out() the
return value was not stored. This may lead out() returning a wrong
value to the caller.

When btree_split_beneath() splits a node to two new children, it will
allocate two blocks: left and right. If right block's allocation
failed, the left block will be unlocked and marked dirty. If this
happened, the left block'ss content is zero, because it wasn't
initialized with the btree struct before the attempot to allocate the
right block. Upon return, when flushing the left block to disk, the
validator will fail when check this block. Then a BUG_ON is raised.
Fix this by completely initializing the left block before allocating and
initializing the right block.

[Why]
The only place where state->max_bpc is updated on the connector is
at the start of atomic check during drm_atomic_connector_check. It
isn't updated when adding the connectors to the atomic state after
the fact. It also doesn't necessarily reflect the right value when
called in amdgpu during mode validation outside of atomic check.
This can cause the wrong bpc to be used even if the max_requested_bpc
is the correct value.
[How]
Don't rely on state->max_bpc reflecting the real bpc value and just
do the min(...) based on display info bpc and max_requested_bpc.

We need to set certain power gating flags after we determine
if the firmware version is sufficient to support gfxoff.
Previously we set the pg flags in early init, but we later
we might have disabled gfxoff if the firmware versions didn't

determine whether or not to support gfxoff.

Change the "frontend" dust_remove_block, dust_add_block, and

of the sector number corresponding to the "dust block number".
For the "backend" functions dust_map_read and dust_map_write,
right-shift by sect_per_block_shift. This fixes the inability to
emulate failure beyond the first sector of each "dust block" (for

Pull kernel thread signal handling fix from Eric Biederman:
"I overlooked the fact that kernel threads are created with all signals
set to SIG_IGN, and accidentally caused a regression in cifs and drbd
when replacing force_sig with send_sig.
This is my fix for that regression. I add a new function
allow_kernel_signal which allows kernel threads to receive signals
sent from the kernel, but continues to ignore all signals sent from
userspace. This ensures the user space interface for cifs and drbd
remain the same.
These kernel threads depend on blocking networking calls which block
until something is received or a signal is pending. Making receiving
of signals somewhat necessary for these kernel threads.
Perhaps someday we can cleanup those interfaces and remove
allow_kernel_signal. If not allow_kernel_signal is pretty trivial and
clearly documents what is going on so I don't think we will mind
carrying it"

When calling request_threaded_irq() with a CP2112, the function
cp2112_gpio_irq_startup() is called in a IRQ context.
Therefore we can not sleep, and we can not call
cp2112_gpio_direction_input() there.
Move the call to cp2112_gpio_direction_input() earlier to have a working
driver.

Distance values reported by 2nd-gen Intuos tablets are on an inverted
scale (0 == far, 63 == near). We need to change them over to a normal
scale before reporting to userspace or else userspace drivers and
applications can get confused.

My recent to change to only use force_sig for a synchronous events
wound up breaking signal reception cifs and drbd. I had overlooked
the fact that by default kthreads start out with all signals set to
SIG_IGN. So a change I thought was safe turned out to have made it
impossible for those kernel thread to catch their signals.
Reverting the work on force_sig is a bad idea because what the code
was doing was very much a misuse of force_sig. As the way force_sig
ultimately allowed the signal to happen was to change the signal
handler to SIG_DFL. Which after the first signal will allow userspace
to send signals to these kernel threads. At least for
wake_ack_receiver in drbd that does not appear actively wrong.
So correct this problem by adding allow_kernel_signal that will allow
signals whose siginfo reports they were sent by the kernel through,
but will not allow userspace generated signals, and update cifs and
drbd to call allow_kernel_signal in an appropriate place so that their
thread can receive this signal.
Fixing things this way ensures that userspace won't be able to send
signals and cause problems, that it is clear which signals the
threads are expecting to receive, and it guarantees that nothing
else in the system will be affected.
This change was partly inspired by similar cifs and drbd patches that
added allow_signal.

Each iteration of for_each_child_of_node puts the previous
node, but in the case of a goto from the middle of the loop, there is
no put, thus causing a memory leak. Hence add an of_node_put before the
goto in two places.

When a Tx timestamp is requested, a pointer to the skb is stored in the
ravb_tstamp_skb struct. This was done without an skb_get. There exists
the possibility that the skb could be freed by ravb_tx_free (when
ravb_tx_free is called from ravb_start_xmit) before the timestamp was
processed, leading to a use-after-free bug.
Use skb_get when filling a ravb_tstamp_skb struct, and add appropriate
frees/consumes when a ravb_tstamp_skb struct is freed.

tc transparently maps the software priority number to hardware. Update
it to pass the major priority which is what most drivers expect. Update
drivers too so they do not need to lshift the priority field of the
flow_cls_common_offload object. The stmmac driver is an exception, since
this code assumes the tc software priority is fine, therefore, lshift it
just to be conservative.

In i2400m_barker_db_init(), 'options_orig' is allocated through kstrdup()
to hold the original command line options. Then, the options are parsed.
However, if an error occurs during the parsing process, 'options_orig' is
not deallocated, leading to a memory leak bug. To fix this issue, free
'options_orig' before returning the error.

The driver name gets exposed in sysfs under /sys/bus/pci/drivers

There's no need to wait until a completion is received to unmap
TX descriptor buffers that have been passed to the hypervisor.
Instead unmap it when the hypervisor call has completed. This patch
avoids the possibility that a buffer will not be unmapped because
a TX completion is lost or mishandled.

FW expects the driver to provide unique flow reference handles
for Tx or Rx flows. When a Tx flow and an Rx flow end up sharing
a reference handle, flow offload does not seem to work.
This could happen in the case of 2 flows having their L2 fields
wildcarded but in different direction.
Fix to incorporate the flow direction as part of the L2 key
v2: Move the dir field to the end of the bnxt_tc_l2_key struct to
fix the warning reported by kbuild test robot <lkp@intel.com>.
There is existing code that initializes the structure using
nested initializer and will warn with the new u8 field added to
the beginning. The structure also packs nicer when this new u8 is
added to the end of the structure [MChan].

Direction of the flow is determined using src_fid. For an RX flow,
src_fid is PF's fid and for TX flow, src_fid is VF's fid. Direction
of the flow must be specified, when getting statistics for that flow.
Currently, for DECAP flow, direction is determined incorrectly, i.e.,
direction is initialized as TX for DECAP flow, instead of RX. Because
of which, stats are not reported for this DECAP flow, though it is
offloaded and there is traffic for that flow, resulting in flow age out.
This patch fixes the problem by determining the DECAP flow's direction
using correct fid. Set the flow direction in all cases for consistency
even if 64-bit flow handle is not used.
