[PATCH 00/38] media sparse/smatch warn fixes

[PATCH 00/38] media sparse/smatch warn fixes

[Mauro Carvalho Chehab]

While I was lately relying on Jenkins to report smatch/sparse issues,
I discovered this week that the reports were missing such warnings

I got it fixed already at builder.linuxtv.org, but there are several new
warnings that got added over time.

This series is meant to solve the ones that are reported on x86_64
without pre-building the smatch database.

It should allow receiving cleaner error reports.

While most of the patches are meant to shut up the static analizers,
some contain real bug fixes.

[PATCH 01/38] media: tda10086: cleanup symbol_rate setting logic

[Mauro Carvalho Chehab]

The original logic had an integer to unsigned integer
conversion, plus a float-point math. While gcc should be
able to do the match at compile time, other compilers might
not do the same. Also, those produce the following warnings
with static code analyzers:

	drivers/media/dvb-frontends/tda10086.c:300 tda10086_set_symbol_rate() warn: unsigned 'symbol_rate' is never less than zero.
	drivers/media/dvb-frontends/tda10086.c:303 tda10086_set_symbol_rate() warn: unsigned 'symbol_rate' is never less than zero.
	drivers/media/dvb-frontends/tda10086.c:306 tda10086_set_symbol_rate() warn: unsigned 'symbol_rate' is never less than zero.

	drivers/media/dvb-frontends/tda10086.c:321 tda10086_set_symbol_rate() warn: unsigned 'symbol_rate' is never less than zero.
	drivers/media/dvb-frontends/tda10086.c:324 tda10086_set_symbol_rate() warn: unsigned 'symbol_rate' is never less than zero.
	drivers/media/dvb-frontends/tda10086.c:327 tda10086_set_symbol_rate() warn: unsigned 'symbol_rate' is never less than zero.

Change the logic to declare the reference constant as unsigned
and to not use float point math.

[PATCH 02/38] media: v4l2-ioctl: avoid memory leaks on some time32 compat functions

[Mauro Carvalho Chehab]

There are some reports about possible memory leaks:

	drivers/media/v4l2-core//v4l2-ioctl.c:3203 video_put_user() warn: check that 'ev32' doesn't leak information (struct has a hole after 'type')
	drivers/media/v4l2-core//v4l2-ioctl.c:3230 video_put_user() warn: check that 'vb32' doesn't leak information (struct has a hole after 'memory')

While smatch seems to be reporting a false positive (line 3203),
there's indeed a possible leak with reserved2 at vb32.

We might have fixed just that one, but smatch checks won't
be able to check leaks at ev32. So, re-work the code in a way
that will ensure that the var contents will be zeroed before
filling it.

With that, we don't need anymore to touch reserved fields.

[PATCH 03/38] media: qt1010: fix usage of unititialized value

[Mauro Carvalho Chehab]

As pointed by smatch:

	drivers/media/tuners/qt1010.c:239 qt1010_init_meas1() error: uninitialized symbol 'val2'.
	drivers/media/tuners/qt1010.c:273 qt1010_init_meas2() error: uninitialized symbol 'val'.

The logic is ok, but it is hard for static analyzers
to parse it, as it depends on a value read in the middle
of a loop.

Also, it takes a while for humans to verify.

Re-write the first function to use a more direct way.

At the second one, I opted to just initialize the read var,
in order to shut up the report.

While here, address a few coding style issues at the
function code.

[PATCH 04/38] media: av7110_v4l: avoid a typecast

[Mauro Carvalho Chehab]

While smatch reports an issue there:

	drivers/media/pci/ttpci/av7110_v4l.c:163 ves1820_set_tv_freq() warn: unsigned 'freq' is never less than zero.
	drivers/media/pci/ttpci/av7110_v4l.c:165 ves1820_set_tv_freq() warn: unsigned 'freq' is never less than zero.

The logic is actually fine. Yet, removing the typecast
shuts up smatch and makes the code more readable.

[PATCH 06/38] media: venus: place extern venus_fw_debug on a header file

[Mauro Carvalho Chehab]

Sparse warns about this symbol:

	drivers/media/platform/qcom/venus/hfi_venus.c:133:5:  warning: symbol 'venus_fw_debug' was not declared. Should it be static?

Because hfi_venus.c doesn't include a header file with the
extern. So, move it to core.h, with is included by both
hfi_venus.c and dbgfs.c.

This way, if something changes with it, warnings or errors
will be produced.

[PATCH 07/38] media: tda10021: avoid casts when using symbol_rate

[Mauro Carvalho Chehab]

The usage of castings and float point when checking for
the setup based at the symbol_rate cause those warnings
with smatch:

	drivers/media/dvb-frontends/tda10021.c:153 tda10021_set_symbolrate() warn: unsigned 'symbolrate' is never less than zero.
	drivers/media/dvb-frontends/tda10021.c:155 tda10021_set_symbolrate() warn: unsigned 'symbolrate' is never less than zero.
	drivers/media/dvb-frontends/tda10021.c:157 tda10021_set_symbolrate() warn: unsigned 'symbolrate' is never less than zero.
	drivers/media/dvb-frontends/tda10021.c:159 tda10021_set_symbolrate() warn: unsigned 'symbolrate' is never less than zero.

While the code should work with gcc, as it will evaluate the
values into a constant before compiling, other compilers
could do otherwise. So, get rid of float pointing math on it,
avoiding the need of doing typecasts.

While here, cleanup some coding style issues at the related
code.

[PATCH 09/38] media: vivid: move the detection part out of vivid_create_instance

[Mauro Carvalho Chehab]

The vivid_create_instance() function is too harry. Smatch can't
process it, because it takes too long.

The detection part is an important piece of it. As such, there
are even comments before and after such block.

So, it makes sense to just move it to a separate function.

[PATCH 11/38] media: vivid: move set_capabilities logic to a separate function

[Mauro Carvalho Chehab]

Move such logic from vivid_create_instance(), as otherwise
smatch takes forever.

The vivid_create_instance() is still a too big for my taste.
So, further cleanups are still needed.

[PATCH 13/38] media: vivid: move the create queues to a separate function

[Mauro Carvalho Chehab]

Instead of placing everything inside vivid_create_instance(),
we can move the part which creates per-type video queues
into a separate function.

[PATCH 14/38] media: vivid: move the devnode creation logic to a separate function

[Mauro Carvalho Chehab]

In order to reduce even further the size of the big
vivid_create_instance() function, let's place the part of the
logic which creates the device nodes into a separate function.

    With this and the past patches, those warnings finally
    vanishes:

            drivers/media/test-drivers/vivid/vivid-core.c: drivers/media/test-drivers/vivid/vivid-core.c:1189 vivid_create_instance() parse error: turning off implications after 60 seconds
            drivers/media/test-drivers/vivid/vivid-core.c: drivers/media/test-drivers/vivid/vivid-core.c:1257 vivid_create_instance() parse error: __split_smt: function too hairy.  Giving up after 303 seconds

The init code also seems more organized after breaking the long
function into a smaller set.

[PATCH 15/38] media: vivid: fix error path

[Mauro Carvalho Chehab]

If something fails after calling v4l2_device_register(),
it should call v4l2_device_put().

[PATCH 16/38] media: videobuf-dma-sg: number of pages should be unsigned long

[Mauro Carvalho Chehab]

As reported by smatch:

	drivers/media/v4l2-core/videobuf-dma-sg.c:245 videobuf_dma_init_kernel() warn: should 'nr_pages << 12' be a 64 bit type?

The printk should not be using %d for the number of pages.

After looking better, the real problem here is that the
number of pages should be long int.

[PATCH 21/38] media: dvb-ttusb-budget: don't use stack for USB transfers

    drivers/media/usb/ttusb-budget/dvb-ttusb-budget.c:430 ttusb_init_controller() error: doing dma on the stack (get_version)

This driver still uses the USB stack for DMA transfers,
which is broken for a long time. I almost dropped this driver,
as there's a high chance that nobody is using it with upstream
Kernels, as we didn't receive any bug reports.

As fixing this won't be hard, I ended opting to fix.

While here, I dropped an ugly hack that implemented read via
a separate function that was just doing a memcpy().

It should be noticed that, during the init phase, there's
a "b4" register that were never initialized, as its buffer
were used just to store the results of "b3" initialization.

[PATCH 22/38] media: dvb-ttusb-budget: cleanup printk logic

[Mauro Carvalho Chehab]

Instead of calling printk(), use pr_foo() macros.

While here, do some cleanup at the printed messages, as some
has __func__, while others have the module name (sometimes
spelled as "ttusb_dvb").

[PATCH 23/38] media: saa7134: avoid a shift overflow

[Mauro Carvalho Chehab]

As reported by smatch:
	drivers/media/pci/saa7134//saa7134-tvaudio.c:686 saa_dsp_writel() warn: should 'reg << 2' be a 64 bit type?

On a 64-bits Kernel, the shift might be bigger than 32 bits.

In real, this should never happen, but let's shut up the warning.

[PATCH 26/38] media: atomisp: cleanup ifdefs from ia_css_debug.c

[Mauro Carvalho Chehab]

There are lots of code dependency there. Get rid of most of
them.

We can't remove everything, as there are some structs that
are conditionally built if ISP2401. So, keep ifdefs only
on such cases.

[PATCH 27/38] media: atomisp: get rid of version-dependent globals

[Mauro Carvalho Chehab]

Replace all occurrences along the atomisp tree for the conditional
compilation macros found at system_global.h, replacing them by
tests wheather ISP2401 is defined or not.

[PATCH 28/38] media: atomisp: get rid of isys_dma.h and isys_dma_local.h

[Mauro Carvalho Chehab]

There aren't much on this abstraction. Just move the defines
to isys_dma_private.h and isys_dma_public.h, cleaning up
the includes.

[PATCH 30/38] media: atomisp: don't check for ISP version for includes

[Mauro Carvalho Chehab]

As there aren't duplicated names anymore, and the end goal
is to do runtime checks between ISP2400 and ISP2401,
remove the part of the Makefile which changes the include
places based on the compile-time version.

This shouldn't cause any effect, but it will make easier
for further patches meant to remove conditional compiler
decisions between ISP versions to be replaced by
runtime ones.

[PATCH 31/38] media: atomisp: unify INPUT error return type

[Mauro Carvalho Chehab]

There is a typedef for INPUT errors. This is different between
ISP2401 and ISP2400. Place both at the same struct, at the
global header file.

[PATCH 32/38] media: atomisp: de-duplicate names at *_input_system_global.h

[Mauro Carvalho Chehab]

There are some duplicated names between the ISP2401 and ISP2400
for the input system, with different meanings.

In order to avoid ubiquity, let's prepend those with the
name of the ISP.

[PATCH 34/38] media: atomisp: remove compile-time tests from input_system_global.h

[Mauro Carvalho Chehab]

Now that there's no duplication between ISP2400 and ISP2401
input system functions, we can include both at the system
global.

[PATCH 35/38] media: atomisp: fix some bad indents

[Mauro Carvalho Chehab]

As smatch reports, there are several bad indents:

    drivers/staging/media/atomisp/pci/hmm/hmm.c:271 hmm_alloc() warn: inconsistent indenting
    drivers/staging/media/atomisp/pci/runtime/bufq/src/bufq.c:390 ia_css_bufq_enqueue_psys_event() warn: inconsistent indenting
    drivers/staging/media/atomisp/pci/runtime/debug/src/ia_css_debug.c:2132 ia_css_debug_dump_isys_state() warn: inconsistent indenting
    drivers/staging/media/atomisp/pci/runtime/binary/src/binary.c:246 sh_css_binary_get_sc_requirements() warn: inconsistent indenting
    drivers/staging/media/atomisp/pci/runtime/binary/src/binary.c:565 ia_css_binary_get_shading_info_type_1() warn: inconsistent indenting
    drivers/staging/media/atomisp/pci/sh_css.c:5109 sh_css_pipes_stop() warn: inconsistent indenting
    drivers/staging/media/atomisp/pci/sh_css.c:8791 ia_css_pipe_create() warn: inconsistent indenting

Some of them are due to ifdefs. Get rid of them by either getting
a common code that would work for both ISP2400 and ISP2401 or
by creating separate functions, one for each ISP version.

Isn't this the same as commit 4ffb879ea648 ("media: media/v4l2-core:
Fix kernel-infoleak
in video_put_user()") that you already applied (aside from the issue
that Laurent
pointed out)?

One pre-existing detail to remember is that the gup/pup routines,
specifically pin_user_pages() in this case, use an "int" for the
incoming nr_pages. (I wonder if that should be changed? It's now
becoming a pitfall.) So it's now possible to overflow.

In other situations like this (see xsdfec_table_write() in
drivers/misc/xilinx_sdfec.c), we've added checks such as:

	u32 n;
	...

	if (WARN_ON_ONCE(n > INT_MAX))
		return -EINVAL;

	nr_pages = n;

	res = pin_user_pages_fast((unsigned long)src_ptr, nr_pages, 0, pages);

...in other words, check the value while it's stored in a 64-bit type,
before sending it down into a 32-bit API.

...other than that, everything else looks fine.
