2018-03-05media: tegra-cec: reset rx_buf_cnt when start bit detectedHans Verkuil
If a start bit is detected, then reset the receive buffer counter to 0. This ensures that no stale data is in the buffer if a message is broken off midstream due to e.g. a Low Drive condition and then retransmitted. The only Rx interrupts we need to listen to are RX_REGISTER_FULL (i.e. a valid byte was received) and RX_START_BIT_DETECTED (i.e. a new message starts and we need to reset the counter).

2018-02-26media: vb2: Makefile: place vb2-trace together with vb2-coreMauro Carvalho Chehab
We don't want a separate module for vb2-trace. That fixes this warning: WARNING: modpost: missing MODULE_LICENSE() in drivers/media/common/videobuf2/vb2-trace.o When building as module. While here, add a SPDX header. Reported-by: Stephen Rothwell <sfr@canb.auug.org.au> Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>
2018-02-23media: Don't let tvp5150_get_vbi() go out of vbi_ram_default arrayMauro Carvalho Chehab
As pointed by Dan, possible values for bits[3:0] of te Line Mode Registers can range from 0x0 to 0xf, but the check logic allow values ranging from 0x0 to 0xe. As static arrays are initialized with zero, using a value without an explicit initializer at the array won't cause any harm.

2018-02-23media: dmxdev: Fix the logic that enables DMA mmap supportMauro Carvalho Chehab
Some conditions required for DVB mmap support to work are reversed. Also, the logic is not too clear. So, improve the logic, making it easier to be handled. PS.: I'm pretty sure that I fixed it while testing, but, somehow, the change got lost. Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>
2018-02-23media: dmxdev: fix error code for invalid ioctlsMauro Carvalho Chehab
Returning -EINVAL when an ioctl is not implemented is a very bad idea, as it is hard to distinguish from other error contitions that an ioctl could lead. Replace it by its right error code: -ENOTTY. Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>

2018-02-23media: videobuf2: fix build issues with vb2-traceMauro Carvalho Chehab
There was a trouble with vb2-trace: instead of being part of VB2 core, it was stored at V4L2 videodev. That was wrong, as it doesn't actually belong to V4L2 core. Now that vb2 is not part of v4l2-core, its trace functions should be moved altogether. So, move it to its rightful place: at videobuf2-core. That fixes those errors: drivers/media/common/videobuf2/videobuf2-core.o: In function `__read_once_size': ./include/linux/compiler.h:183: undefined reference to `__tracepoint_vb2_buf_queue' ./include/linux/compiler.h:183: undefined reference to `__tracepoint_vb2_buf_queue' ./include/linux/compiler.h:183: undefined reference to `__tracepoint_vb2_buf_done' ./include/linux/compiler.h:183: undefined reference to `__tracepoint_vb2_buf_done' ./include/linux/compiler.h:183: undefined reference to `__tracepoint_vb2_qbuf' ./include/linux/compiler.h:183: undefined reference to `__tracepoint_vb2_qbuf' ./include/linux/compiler.h:183: undefined reference to `__tracepoint_vb2_dqbuf' ./include/linux/compiler.h:183: undefined reference to `__tracepoint_vb2_dqbuf' drivers/media/common/videobuf2/videobuf2-core.o:(__jump_table+0x10): undefined reference to `__tracepoint_vb2_buf_queue' drivers/media/common/videobuf2/videobuf2-core.o:(__jump_table+0x28): undefined reference to `__tracepoint_vb2_buf_done' drivers/media/common/videobuf2/videobuf2-core.o:(__jump_table+0x40): undefined reference to `__tracepoint_vb2_qbuf' drivers/media/common/videobuf2/videobuf2-core.o:(__jump_table+0x58): undefined reference to `__tracepoint_vb2_dqbuf' Reported-by: kbuild test robot <fengguang.wu@intel.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>
2018-02-23media: videobuf2: Add VIDEOBUF2_V4L2 Kconfig option for VB2 V4L2 partSakari Ailus
Videobuf2 is now separate from V4L2 and can be now built without it, at least in principle --- enabling videobuf2 in kernel configuration attempts to compile videobuf2-v4l2.c but that will fail if CONFIG_VIDEO_V4L2 isn't enabled. Solve this by adding a separate Kconfig option for videobuf2-v4l2 and make it a separate module as well. This means that drivers now need to choose both the appropriate videobuf2 memory type (VIDEOBUF2_{VMALLOC,DMA_CONTIG,DMA_SG}) and VIDEOBUF2_V4L2 if they need both.

2018-02-11vfs: do bulk POLL* -> EPOLL* replacementLinus Torvalds
This is the mindless scripted replacement of kernel use of POLL* variables as described by Al, done by this script: for V in IN OUT PRI ERR RDNORM RDBAND WRNORM WRBAND HUP RDHUP NVAL MSG; do L=`git grep -l -w POLL$V | grep -v '^t' | grep -v /um/ | grep -v '^sa' | grep -v '/poll.h$'|grep -v '^D'` for f in $L; do sed -i "-es/^\([^\"]*\)\(\<POLL$V\>\)/\\1E\\2/" $f; done done with de-mangling cleanups yet to come. NOTE! On almost all architectures, the EPOLL* constants have the same values as the POLL* constants do. But they keyword here is "almost". For various bad reasons they aren't the same, and epoll() doesn't actually work quite correctly in some cases due to this on Sparc et al. The next patch from Al will sort out the final differences, and we should be all done. Scripted-by: Al Viro <viro@zeniv.linux.org.uk> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs Pull poll annotations from Al Viro: "This introduces a __bitwise type for POLL### bitmap, and propagates the annotations through the tree. Most of that stuff is as simple as 'make ->poll() instances return __poll_t and do the same to local variables used to hold the future return value'. Some of the obvious brainos found in process are fixed (e.g. POLLIN misspelled as POLL_IN). At that point the amount of sparse warnings is low and most of them are for genuine bugs - e.g. ->poll() instance deciding to return -EINVAL instead of a bitmap. I hadn't touched those in this series - it's large enough as it is. Another problem it has caught was eventpoll() ABI mess; select.c and eventpoll.c assumed that corresponding POLL### and EPOLL### were equal. That's true for some, but not all of them - EPOLL### are arch-independent, but POLL### are not. The last commit in this series separates userland POLL### values from the (now arch-independent) kernel-side ones, converting between them in the few places where they are copied to/from userland. AFAICS, this is the least disruptive fix preserving poll(2) ABI and making epoll() work on all architectures. As it is, it's simply broken on sparc - try to give it EPOLLWRNORM and it will trigger only on what would've triggered EPOLLWRBAND on other architectures.

2018-01-30media: v4l2-compat-ioctl32.c: refactor compat ioctl32 logicDaniel Mentz
The 32-bit compat v4l2 ioctl handling is implemented based on its 64-bit equivalent. It converts 32-bit data structures into its 64-bit equivalents and needs to provide the data to the 64-bit ioctl in user space memory which is commonly allocated using compat_alloc_user_space(). However, due to how that function is implemented, it can only be called a single time for every syscall invocation. Supposedly to avoid this limitation, the existing code uses a mix of memory from the kernel stack and memory allocated through compat_alloc_user_space(). Under normal circumstances, this would not work, because the 64-bit ioctl expects all pointers to point to user space memory. As a workaround, set_fs(KERNEL_DS) is called to temporarily disable this extra safety check and allow kernel pointers. However, this might introduce a security vulnerability: The result of the 32-bit to 64-bit conversion is writeable by user space because the output buffer has been allocated via compat_alloc_user_space(). A malicious user space process could then manipulate pointers inside this output buffer, and due to the previous set_fs(KERNEL_DS) call, functions like get_user() or put_user() no longer prevent kernel memory access. The new approach is to pre-calculate the total amount of user space memory that is needed, allocate it using compat_alloc_user_space() and then divide up the allocated memory to accommodate all data structures that need to be converted. An alternative approach would have been to retain the union type karg that they allocated on the kernel stack in do_video_ioctl(), copy all data from user space into karg and then back to user space. However, we decided against this approach because it does not align with other compat syscall implementations. Instead, we tried to replicate the get_user/put_user pairs as found in other places in the kernel: if (get_user(clipcount, &up->clipcount) || put_user(clipcount, &kp->clipcount)) return -EFAULT; Notes from hans.verkuil@cisco.com: This patch was taken from: https://github.com/LineageOS/android_kernel_samsung_apq8084/commit/97b733953c06e4f0398ade18850f0817778255f7 Clearly nobody could be bothered to upstream this patch or at minimum tell us :-( We only heard about this a week ago. This patch was rebased and cleaned up. Compared to the original I also swapped the order of the convert_in_user arguments so that they matched copy_in_user. It was hard to review otherwise. I also replaced the ALLOC_USER_SPACE/ALLOC_AND_GET by a normal function. Fixes: 6b5a9492ca ("v4l: introduce string control support.")

[-Werror=implicit-function-declaration] gpiod_direction_output(ov7740->pwdn_gpio, 0); drivers/media/i2c/ov7740.c:914:4: error: 'GPIOD_OUT_HIGH' undeclared (first use in this function); did you mean 'GPIOF_INIT_HIGH'? Changing it to use the correct header file solves the problem.

2018-01-23media: entity: Add a nop variant of media_entity_cleanupSakari Ailus
Add nop variant of media_entity_cleanup. This allows calling media_entity_cleanup whether or not Media controller is enabled, simplifying driver code. Also drop #ifdefs on a few drivers around media_entity_cleanup().

2018-01-23media: ov5640: fix spurious streamon failuresHugues Fruchet
Time to time, stream on is failing with a strange positive error. Error code is returned erroneously by ov5640_set_ctrl_exposure() due to ov5640_get_vts() return value wrongly treated as error. Fix this by forcing ret to 0 after ov5640_get_vts() success call, in order that ret is set to success for rest of code sequence.

The rc5 protocol does not have a leading pulse or space, but we encode the first bit using a single leading pulse. For other protocols, the leading pulse or space does not represent any bit. So, don't remove the first bit if a leading pulse is present.
