The commit 8dfbcc4351a0 ("[media] xc2028: avoid use after free") tried
to address the reported use-after-free by clearing the reference.
However, it's clearing the wrong pointer; it sets NULL to
priv->ctrl.fname, but it's anyway overwritten by the next line
memcpy(&priv->ctrl, p, sizeof(priv->ctrl)).
OTOH, the actual code accessing the freed string is the strcmp() call
with priv->fname:
if (!firmware_name[0] && p->fname &&
priv->fname && strcmp(p->fname, priv->fname))
free_firmware(priv);
where priv->fname points to the previous file name, and this was
already freed by kfree().
For fixing the bug properly, this patch does the following:
- Keep the copy of firmware file name in only priv->fname,
priv->ctrl.fname isn't changed;
- The allocation is done only when the firmware gets loaded;
- The kfree() is called in free_firmware() commonly

Per PCIe spec r3.0, sec 2.3.1.1, the Read Completion Boundary (RCB)
determines the naturally aligned address boundaries on which a Read Request
may be serviced with multiple Completions:
- For a Root Complex, RCB is 64 bytes or 128 bytes
This value is reported in the Link Control Register
Note: Bridges and Endpoints may implement a corresponding command bit
which may be set by system software to indicate the RCB value for the
Root Complex, allowing the Bridge/Endpoint to optimize its behavior
when the Root Complex’s RCB is 128 bytes.
- For all other system elements, RCB is 128 bytes
Per sec 7.8.7, if a Root Port only supports a 64-byte RCB, the RCB of all
downstream devices must be clear, indicating an RCB of 64 bytes. If the
Root Port supports a 128-byte RCB, we may optionally set the RCB of
downstream devices so they know they can generate larger Completions.
Some BIOSes supply an _HPX that tells us to set RCB, even though the Root
Port doesn't have RCB set, which may lead to Malformed TLP errors if the
Endpoint generates completions larger than the Root Port can handle.
The IBM x3850 X6 with BIOS version -[A8E120CUS-1.30]- 08/22/2016 supplies
such an _HPX and a Mellanox MT27500 ConnectX-3 device fails to initialize:
mlx4_core 0000:41:00.0: command 0xfff timed out (go bit not cleared)
mlx4_core 0000:41:00.0: device is going to be reset
mlx4_core 0000:41:00.0: Failed to obtain HW semaphore, aborting
mlx4_core 0000:41:00.0: Fail to reset HCA
------------[ cut here ]------------
kernel BUG at drivers/net/ethernet/mellanox/mlx4/catas.c:193!
After 6cd33649fa83 ("PCI: Add pci_configure_device() during enumeration")
and 7a1562d4f2d0 ("PCI: Apply _HPX Link Control settings to all devices
with a link"), we apply _HPX settings to *all* devices, not just those
hot-added after boot.
Before 7a1562d4f2d0, we didn't touch the Mellanox RCB, and the device
worked. After 7a1562d4f2d0, we set its RCB to 128, and it failed.
Set the RCB to 128 iff the Root Port supports a 128-byte RCB. Otherwise,
set RCB to 64 bytes. This effectively ignores what _HPX tells us about
RCB.
Note that this change only affects _HPX handling. If we have no _HPX, this
does nothing with RCB.

tile: avoid using clocksource_cyc2ns with absolute cycle count
|
|
In the user manual of A33 SoC, the bit 22 and 23 of pll-mipi control
register is called "LDO{1,2}_EN", and according to the BSP source code
from Allwinner [1], the LDOs are enabled during the clock's enabling
process.
The clock failed to generate output if the two LDOs are not enabled.
Add the two bits to the clock's gate bits, so that the LDOs are enabled
when the PLL is enabled.

For large values of "mult" and long uptimes, the intermediate
result of "cycles * mult" can overflow 64 bits. For example,
the tile platform calls clocksource_cyc2ns with a 1.2 GHz clock;
we have mult = 853, and after 208.5 days, we overflow 64 bits.
Since clocksource_cyc2ns() is intended to be used for relative
cycle counts, not absolute cycle counts, performance is more
importance than accepting a wider range of cycle values. So,
just use mult_frac() directly in tile's sched_clock().
Commit 4cecf6d401a0 ("sched, x86: Avoid unnecessary overflow
in sched_clock") by Salman Qazi results in essentially the same
generated code for x86 as this change does for tile. In fact,
a follow-on change by Salman introduced mult_frac() and switched
to using it, so the C code was largely identical at that point too.
Peter Zijlstra then added mul_u64_u32_shr() and switched x86
to use it. This is, in principle, better; by optimizing the
64x64->64 multiplies to be 32x32->64 multiplies we can potentially
save some time. However, the compiler piplines the 64x64->64
multiplies pretty well, and the conditional branch in the generic
mul_u64_u32_shr() causes some bubbles in execution, with the
result that it's pretty much a wash. If tilegx provided its own
implementation of mul_u64_u32_shr() without the conditional branch,
we could potentially save 3 cycles, but that seems like small gain
for a fair amount of additional build scaffolding; no other platform
currently provides a mul_u64_u32_shr() override, and tile doesn't
currently have an <asm/div64.h> header to put the override in.
Additionally, gcc currently has an optimization bug that prevents
it from recognizing the opportunity to use a 32x32->64 multiply,
and so the result would be no better than the existing mult_frac()
until such time as the compiler is fixed.
For now, just using mult_frac() seems like the right answer.

When PCIe port PM is not enabled (system BIOS is pre-2015 or the
pcie_port_pm=off parameter is set), legacy ATPX PM should still be
marked as supported. Otherwise the GPU can fail to power on after
runtime suspend. This affected a Dell Inspiron 5548.
Ideally the BIOS date in the PCI core is lowered to 2013 (the first year
where hybrid graphics platforms using power resources was introduced),
but that seems more risky at this point and would not solve the
pcie_port_pm=off issue.

When user tried to read some fields like hysteresis from IIO sysfs on some
systems, it fails. The reason is that this field is a byte field and caller
of sensor_hub_get_feature() passes a buffer of 4 bytes. Here the function
sensor_hub_get_feature() copies the single byte from the report to the
caller buffer and returns "1" as the number of bytes copied. So caller
can use the return value.
But this is done by multiple callers, so if we just change the
sensor_hub_get_feature so that caller buffer is initialized with 0s
then we don't to change all functions.

Since commit 6f3b911d5f29b98 ("can: bcm: add support for CAN FD frames") the
CAN broadcast manager supports CAN and CAN FD data frames.
As these data frames are embedded in struct can[fd]_frames which have a
different length the access to the provided array of CAN frames became
dependend of op->cfsiz. By using a struct canfd_frame pointer for the array of
CAN frames the new offset calculation based on op->cfsiz was accidently applied
to CAN FD frame element lengths.
This fix makes the pointer to the arrays of the different CAN frame types a
void pointer so that the offset calculation in bytes accesses the correct CAN
frame elements.

This reverts commit 4dd1837d7589f468ed109556513f476e7a7f9121.
Moving the exports for assembly code into the assembly files breaks
KSYM trimming, but also breaks modversions.
While fixing the KSYM trimming is trivial, fixing modversions brings
us to a technically worse position that we had prior to the above
change:
- We end up with the prototype definitions divorsed from everything
else, which means that adding or removing assembly level ksyms
become more fragile:
* if adding a new assembly ksyms export, a missed prototype in
asm-prototypes.h results in a successful build if no module in
the selected configuration makes use of the symbol.
* when removing a ksyms export, asm-prototypes.h will get forgotten,
with armksyms.c, you'll get a build error if you forget to touch
the file.
- We end up with the same amount of include files and prototypes,
they're just in a header file instead of a .c file with their
exports.
As for lines of code, we don't get much of a size reduction:
(original commit)
47 files changed, 131 insertions(+), 208 deletions(-)
(fix for ksyms trimming)
7 files changed, 18 insertions(+), 5 deletions(-)
(two fixes for modversions)
1 file changed, 34 insertions(+)
3 files changed, 7 insertions(+), 2 deletions(-)
which results in a net total of only 25 lines deleted.
As there does not seem to be much benefit from this change of approach,
revert the change.

A correct bugfix introduced a harmless warning that shows up with gcc-7:
fs/nfs/callback.c: In function 'nfs_callback_up':
fs/nfs/callback.c:214:14: error: array subscript is outside array bounds [-Werror=array-bounds]
What happens here is that the 'minorversion == 0' check tells the
compiler that we assume minorversion can be something other than 0,
but when CONFIG_NFS_V4_1 is disabled that would be invalid and
result in an out-of-bounds access.
The added check for IS_ENABLED(CONFIG_NFS_V4_1) tells gcc that this
really can't happen, which makes the code slightly smaller and also
avoids the warning.
The bugfix that introduced the warning is marked for stable backports,
we want this one backported to the same releases.

Andre Noll reported panics after my recent fix (commit 34fad54c2537
"net: __skb_flow_dissect() must cap its return value")
After some more headaches, Alexander root caused the problem to
init_default_flow_dissectors() being called too late, in case
a network driver like IGB is not a module and receives DHCP message
very early.
Fix is to call init_default_flow_dissectors() much earlier,
as it is a core infrastructure and does not depend on another
kernel service.

We are not checking the return value from a call to wm_adsp_buffer_init
it looks like this used to be returned at the bottom of the function but
probably got missed when more error paths were added. This patch adds
the appropriate error check.

The internal codec on A23/A33/H3 is split into 2 parts. The
analog path controls are routed through an embedded custom register
bus accessed through the PRCM block.
The SoCs share a common set of inputs, outputs, and audio paths.
The following table lists the differences.
----------------------------------------
| Feature \ SoC | A23 | A33 | H3 |
----------------------------------------
| Headphone | v | v | |
----------------------------------------
| Line Out | | | v |
----------------------------------------
| Phone In/Out | v | v | |
----------------------------------------
Add an ASoC component driver for it. This should be tied to the codec
audio card as an auxiliary device. This patch adds the commont paths
and controls, and variant specific headphone out and line out.

IOMMU needs DMA mapping function to use it. One solution is that
we can use DMA mapped dev on snd_pcm_lib_preallocate_pages_for_all()
for SNDRV_DMA_TYPE_DEV. But pcm_new and dma map timing are mismatched.
Thus, this patch uses SNDRV_DMA_TYPE_CONTINUOUS for pcm_new,
and use dma_sync_single_for_xxx() for each transfer.

Current Renesas Sound driver requests DMA channel when .probe timing,
and release it when .remove timing. And use DMA on .start/.stop
But, Audio DMAC power ON was handled when request timing (= .probe),
and power OFF was when release timing (= .remove).
This means Audio DMAC power is always ON during driver was enabled.
The best choice to solve this issue is that DMAEngine side handle
this. But current DMAEngine API design can't solve atmic/non-atmic
context issue for power ON/OFF. So next better choice is sound
driver request/release DMA channel each time. This patch do it

We were adding firmware controls as card controls (using
snd_soc_add_codec_controls). The DSP is part of a specific codec so
we should be adding them as codec controls. Adding as codec controls
also means that if the codec has a name_prefix it will be added to
the control name, which won't happen when adding as a card control.
As that was the only use of the card pointer in struct wm_adsp it can
be removed.
For ADSP2 codecs a wm_adsp2_codec_probe() was added since the original
control handling was written, and that's the logical place to store a
pointer to the codec rather than delaying it until the codec is
powered-up.
For ADSP1 we don't use a codec_probe() stage so the codec pointer
initialization replaces the original card pointer initialization in
wm_adsp1_event().

cht_bsw_rt5645 driver allocates the own codec_id string but doesn't
release it. For simplicity, put the string in cht_mc_private; then
the string is allocated in a shot and released altogether.
