8a24280b11 media: dvb: move most compat_ioctl handling into drivers
Most DVB audio and video ioctl commands are completely compatible,
and are implemented by just two drivers: ttpci and ivtv. In both
cases, we can use the same ioctl handler for both native and
compat ioctl handling, and remove the entries from the global
lookup table.

In case of ttpci, this directly hooks into the file_operations
structure, and for ivtv, we have to set the compat_ioctl32
method in v4l2_file_operations. For all I can tell, setting it
to video_ioctl2 will still do the right thing for all commands.

Note that for the VIDEO_STILLPICTURE and VIDEO_GET_EVENT commands,
a translation handler in fs/compat_ioctl.c is still used. This
works because the command numbers are different on 32-bit
systems.

447d668553 media: v4l2-common: v4l2_spi_subdev_init : generate unique name
While v4l2_i2c_subdev_init does give a unique name to the subdev, matching
the one appearing in dmesg for messages generated by dev_info and friends
(e.g. imx185 30-0010), v4l2_spi_subdev_init does a poor job, copying only
the driver name, but not the dev_name(), yielding e.g. "imx185", but
missing the "spi1.1" part, and not generating a unique name.

Fix that.

dfb7bcf0af media: mxl5xx: add a fall-trough annotation
As pointed by Daniel Scheller <d.scheller@gmx.net>, sparse
warns that a segment may fall through. We're deprecating
this warning in favor of gcc 8 equivalent warning.

In this specific case, the code for DVB-S applies for DVB-S2.
In a matter of fact, several things there (like rolloff
factor logic) assume that the transponder is DVB-S2.

So, add the corresponding fall-trough markup, for gcc to
properly ignore it.

The device information structure is currently copied field by field in

fields.

Fix this by storing the uvc_device_info pointer in the uvc_device
structure. As a result the uvc_device meta_format field can be removed.
The quirks field, however, needs to stay as it can be modified through a
module parameter.

As not all device have an information structure, we declare a global
"NULL" info instance that is used as a fallback when the driver_info is
empty.

Fix error handling of v4l2_ctrl creation by inspecting the ctrl.error flag
instead of testing for each returned value correctness.

As reported by Dan Carpenter returning PTR_ERR() on the v4l2_ctrl_new_std()
return value is also wrong, as that function return NULL on error.

While at there re-order the cleanup path to respect the operation inverse

4d471563d8 media: i2c: Fix pm_runtime_get_if_in_use() usage in sensor drivers
pm_runtime_get_if_in_use() returns -EINVAL if runtime PM is disabled. This
should not be considered an error. Generally the driver has enabled
runtime PM already so getting this error due to runtime PM being disabled
will not happen.

Instead of checking for lesser or equal to zero, check for zero only.
Address this for drivers where this pattern exists.

This patch has been produced using the following command:

$ git grep -l pm_runtime_get_if_in_use -- drivers/media/i2c/ | \
  xargs perl -i -pe 's/(pm_runtime_get_if_in_use\(.*\)) \<\= 0/!$1/'

d5acba26bf Char/Misc driver patches for 4.19-rc1
Here is the bit set of char/misc drivers for 4.19-rc1
 
 There is a lot here, much more than normal, seems like everyone is
 writing new driver subsystems these days...  Anyway, major things here
 are:
 	- new FSI driver subsystem, yet-another-powerpc low-level
 	  hardware bus
 	- gnss, finally an in-kernel GPS subsystem to try to tame all of
 	  the crazy out-of-tree drivers that have been floating around
 	  for years, combined with some really hacky userspace
 	  implementations.  This is only for GNSS receivers, but you
 	  have to start somewhere, and this is great to see.
 Other than that, there are new slimbus drivers, new coresight drivers,
 new fpga drivers, and loads of DT bindings for all of these and existing
 drivers.
 
 Full details of everything is in the shortlog.
 
 All of these have been in linux-next for a while with no reported
 issues.

f863ae594d media: platform: cros-ec-cec: Fix dependency on MFD_CROS_EC
Without the MFD driver, we run into a link error:

drivers/media/platform/cros-ec-cec/cros-ec-cec.o: In function `cros_ec_cec_transmit':
cros-ec-cec.c:(.text+0x474): undefined reference to `cros_ec_cmd_xfer_status'

cros-ec-cec.c:(.text+0x77d): undefined reference to `cros_ec_cmd_xfer_status'

As we can compile-test all the dependency, the extra '| COMPILE_TEST' is
not needed to get the build coverage, and we can simply turn MFD_CROS_EC
into a hard dependency to make it build in all configurations.

As sparse complains:

when a struct is initialized with { 0 }, actually the first
element of the struct is initialized with zeros, initializing the

on nested structs.

So, instead, use the gcc-specific syntax for that (with is used
broadly inside the Kernel), initializing it with {};

As Ian pointed out, adding a '-' to the fallthrough seems to meet

the comment fits into a single line.

So, replace by a single line the comments that were broken into

3354b54f9f media: vivid: shut up warnings due to a non-trivial logic
The vivid driver uses a complex logic to save one kalloc/kfree
allocation. That non-trivial way of allocating data causes
smatch to warn:
	drivers/media/platform/vivid/vivid-core.c:869 vivid_create_instance() warn: potentially one past the end of array 'dev->query_dv_timings_qmenu[dev->query_dv_timings_size]'
	drivers/media/platform/vivid/vivid-core.c:869 vivid_create_instance() warn: potentially one past the end of array 'dev->query_dv_timings_qmenu[dev->query_dv_timings_size]'

I also needed to read the code several times in order to understand
what it was desired there. It turns that the logic was right,
although confusing to read.

As it is doing allocations on a non-standard way, let's add some
documentation while shutting up the false positive.

845b978a87 media: rtl28xxu: be sure that it won't go past the array size
smatch warns that the RC query code could go past the array size:

	drivers/media/usb/dvb-usb-v2/rtl28xxu.c:1757 rtl2832u_rc_query() error: buffer overflow 'buf' 128 <= 130
	drivers/media/usb/dvb-usb-v2/rtl28xxu.c:1758 rtl2832u_rc_query() error: buffer overflow 'buf' 128 <= 130

The driver logic gets the length of the IR RX buffer with:

        ret = rtl28xxu_rd_reg(d, IR_RX_BC, &buf[0]);
	...
        len = buf[0];

In thesis, this could range between 0 and 255 [1].

While this should never happen in practice, due to hardware limits,
smatch is right when it complains about that, as there's nothing at
the logic that would prevent it. So, if for whatever reason, buf[0]
gets filled by rtl28xx read functions with a value bigger than 128,
it will go past the array.

So, add an explicit check.

[1] I've no idea why smatch thinks that the maximum value is 130.
I double-checked the code several times. Was unable to find any
reason for assuming 130. Perhaps smatch is not properly parsing
u8 here?

Daniel Borkmann says:

====================
pull-request: bpf-next 2018-08-07

The following pull-request contains BPF updates for your *net-next* tree.

The main changes are:

1) Add cgroup local storage for BPF programs, which provides a fast
   accessible memory for storing various per-cgroup data like number
   of transmitted packets, etc, from Roman.

2) Support bpf_get_socket_cookie() BPF helper in several more program
   types that have a full socket available, from Andrey.

3) Significantly improve the performance of perf events which are
   reported from BPF offload. Also convert a couple of BPF AF_XDP
   samples overto use libbpf, both from Jakub.

4) seg6local LWT provides the End.DT6 action, which allows to
   decapsulate an outer IPv6 header containing a Segment Routing Header.
   Adds this action now to the seg6local BPF interface, from Mathieu.

5) Do not mark dst register as unbounded in MOV64 instruction when
   both src and dst register are the same, from Arthur.

6) Define u_smp_rmb() and u_smp_wmb() to their respective barrier
   instructions on arm64 for the AF_XDP sample code, from Brian.

7) Convert the tcp_client.py and tcp_server.py BPF selftest scripts
   over from Python 2 to Python 3, from Jeremy.

8) Enable BTF build flags to the BPF sample code Makefile, from Taeung.

9) Remove an unnecessary rcu_read_lock() in run_lwt_bpf(), from Taehee.

10) Several improvements to the README.rst from the BPF documentation
    to make it more consistent with RST format, from Tobin.

11) Replace all occurrences of strerror() by calls to strerror_r()
    in libbpf and fix a FORTIFY_SOURCE build error along with it,
    from Thomas.

12) Fix a bug in bpftool's get_btf() function to correctly propagate
    an error via PTR_ERR(), from Yue.

3e737e3943 media: vsp1: use kernel __packed for structures
The kernel provides a __packed definition to abstract away from the
compiler specific attributes tag.

Convert all packed structures in VSP1 to use it.

The GCC documentation [0] describes this attribute as "the structure or
union is placed to minimize the memory required".

The Keil compiler documentation at [1] warns that the use of this
attribute can cause a performance penalty in the event that the compiler
can not deduce the allignment of each field.

Careful examination of the object code generated both with and without
this attribute shows that these structures are accessed identically and
are not affected by any performance penalty. The structures are
correctly aligned and padded to match the needs of the hardware already.

This patch does not serve to make a decision as to the use of the
attribute, but purely to clean up the code to use the kernel defined
abstraction as per [2].

Split off all code specific to the MaxSX8 cards to a separate ddbridge-sx8
module and hook it up in the Makefile. This also adds evaluation of the
mci_type to allow for using different attach handling for different cards.
As different cards can implement things differently (ie. support differing
frontend_ops, and have different base structs being put ontop of the
common mci_base struct), this introduces the mci_cfg struct which is
initially used to hold a few specifics to the -sx8 submodule. While at it,
the handling of the i/q mode is adjusted slightly. Besides this and
handling mci_base and sx8_base struct pointers where needed, all code
is copied unmodified from ddbridge-mci.c.

d33be4327e media: ddbridge: probe for LNBH25 chips before attaching
In demod_attach_stv0910(), the LNBH25 IC is being blindly attached and,
if the result is bad, blindly attached on another possible I2C address.
The LNBH25 uses it's set_voltage function to test for the IC and will
print an error to the kernel log on failure. Prevent this by probing
the possible I2C address and use this (and only this) to attach the
LNBH25 I2C driver. This also allows the stv0910 attach function to be
a bit cleaner.

Picked up from the upstream dddvb GIT and adapted for the LNBH25 driver
variant from the kernel tree.

157eb9a0b7 media: em28xx: explicitly disable TS packet filter
The em28xx driver never touched the EM2874 register bits that control
the transport stream packet filters, leaving them at whatever default
the firmware has set. E.g. the Pinnacle 290e disables them by default,
while the Hauppauge WinTV dualHD enables discarding NULL packets by
default.

However, some applications require NULL packets, e.g. to determine the
load in DOCSIS segments, so discarding NULL packets is undesired for
such applications.

This patch simply extends the bit mask when starting or stopping the
transport stream packet capture, so that the filter bits are cleared.
It has been verified that this makes the Hauppauge WinTV dualHD pass
an unfiltered DVB-C stream including NULL packets, which it didn't
before.

Friio device contains "gl861" bridge and "tc90522" demod,
for which the separate drivers are already in the kernel.
But friio driver was monolithic and did not use them,
practically copying those features.
This patch decomposes friio driver into sub drivers and
re-uses existing ones, thus reduces some code.

It adds some features to gl861,
to support the friio-specific init/config of the devices
and implement i2c communications to the tuner via demod
with USB vendor requests.

8eb0e64219 media: v4l: vsp1: Fix deadlock in VSPDL DRM pipelines
The VSP uses a lock to protect the BRU and BRS assignment when
configuring pipelines. The lock is taken in vsp1_du_atomic_begin() and
released in vsp1_du_atomic_flush(), as well as taken and released in
vsp1_du_setup_lif(). This guards against multiple pipelines trying to
assign the same BRU and BRS at the same time.

The DRM framework calls the .atomic_begin() operations in a loop over
all CRTCs included in an atomic commit. On a VSPDL (the only VSP type
where this matters), a single VSP instance handles two CRTCs, with a
single lock. This results in a deadlock when the .atomic_begin()
operation is called on the second CRTC.

The DRM framework serializes atomic commits that affect the same CRTCs,
but doesn't know about two CRTCs sharing the same VSPDL. Two commits
affecting the VSPDL LIF0 and LIF1 respectively can thus race each other,
hence the need for a lock.

This could be fixed on the DRM side by forcing serialization of commits
affecting CRTCs backed by the same VSPDL, but that would negatively
affect performances, as the locking is only needed when the BRU and BRS
need to be reassigned, which is an uncommon case.

The lock protects the whole .atomic_begin() to .atomic_flush() sequence.
The only operation that can occur in-between is vsp1_du_atomic_update(),
which doesn't touch the BRU and BRS, and thus doesn't need to be
protected by the lock. We can thus only take the lock around the
pipeline setup calls in vsp1_du_atomic_flush(), which fixes the
deadlock.

4faeaf9c0f media: s5p-mfc: Fix buffer look up in s5p_mfc_handle_frame_{new, copy_time} functions
Look up of buffers in s5p_mfc_handle_frame_new, s5p_mfc_handle_frame_copy_time
functions is not working properly for DMA addresses above 2 GiB. As a result
flags and timestamp of returned buffers are not set correctly and it breaks
operation of GStreamer/OMX plugins which rely on the CAPTURE buffer queue
flags.

Due to improper return type of the get_dec_y_adr, get_dspl_y_adr callbacks
and sign bit extension these callbacks return incorrect address values,
e.g. 0xfffffffffefc0000 instead of 0x00000000fefc0000. Then the statement:

"if (vb2_dma_contig_plane_dma_addr(&dst_buf->b->vb2_buf, 0) == dec_y_addr)"

is always false, which breaks looking up capture queue buffers.

To ensure proper matching by address u32 type is used for the DMA
addresses. This should work on all related SoCs, since the MFC DMA
address width is not larger than 32-bit.

Changes done in this patch are minimal as there is a larger patch series
pending refactoring the whole driver.

9db3bbf58b media: v4l2-mem2mem: Fix missing v4l2_m2m_try_run call
Commit 34dbb848d5 ("media: mem2mem: Remove excessive try_run call")
removed a redundant call to v4l2_m2m_try_run but instead introduced
a bug. Consider the following case:

 1) Context A schedules, queues and runs job A.
 2) While the m2m device is running, context B schedules
    and queues job B. Job B cannot run, because it has to
    wait for job A.
 3) Job A completes, calls v4l2_m2m_job_finish, and tries
    to queue a job for context A, but since the context is
    empty it won't do anything.

In this scenario, queued job B will never run. Fix this by calling
v4l2_m2m_try_run from v4l2_m2m_try_schedule.

While here, add more documentation to these functions.

39dd23dc9d media: imx274: add cropping support via SELECTION API
Currently this driver does not support cropping. The supported modes
are the following, all capturing the entire area:

 - 3840x2160, 1:1 binning (native sensor resolution)
 - 1920x1080, 2:1 binning
 - 1280x720,  3:1 binning

The VIDIOC_SUBDEV_S_FMT ioctl chooses among these 3 configurations the
one that matches the requested format.

Add cropping support via VIDIOC_SUBDEV_S_SELECTION: with target
V4L2_SEL_TGT_CROP to choose the captured area, with
V4L2_SEL_TGT_COMPOSE to choose the output resolution.

To maintain backward compatibility we also allow setting the compose
format via VIDIOC_SUBDEV_S_FMT. To obtain this, compose rect and
output format are computed in the common helper function
__imx274_change_compose(), which sets both to the same width/height
values.

Cropping also calls __imx274_change_compose() whenever cropping rect
size changes in order to reset the compose rect (and output format
size) for 1:1 binning.

Also rename enum imx274_mode to imx274_binning (and its values from
IMX274_MODE_BINNING_* to IMX274_BINNING_*). Without cropping, the two
naming are equivalent. With cropping, the resolution could be
different, e.g. using 2:1 binning mode to crop 1200x960 and output a
600x480 format. Using binning in the names avoids any
misunderstanding. For the same reason, replace the 'size' field in
struct imx274_frmfmt with 'bin_ratio'.
