Since commit 9a4c7e68f7e0 ("media: tvp5150: convert register access to regmap")' the driver supports regmap. Now we can drop the handmade bit update sequence and move to the regmap provided helpers. Signed-off-by: -

Regmap provides built in debugging, caching and provides dedicated accessors for bit manipulations in registers, which make the following changes a lot simpler. Signed-off-by:

The function only consists of a single switch case block without a default case. Unsupported control requests are indicated by the -EINVAL return code trough the last return statement at the end of the function. So exiting just the switch case block returns the -EINVAL error code but the hue control is supported and a zero should be returned instead. Replace the break by a 'return 0' to fix this behaviour.

Now that all drivers are using pad signal types, we can get rid of the global static definition, as routes are stablished using the pad signal type. The tuner and IF-PLL pads are now used only by the tuner core, so move the definitions to be there. Acked-by:

Instead of relying on a static map for pids, use the new sig_type "taint" type to setup the pipelines with the same tipe between different entities. Acked-by:
-
Mauro Carvalho Chehab authored
Consumer devices are provided with a wide different range of types supported by the same driver, allowing different configutations. In order to make easier to setup media controller links, "taint" pads with the signal type it carries. While here, get rid of DEMOD_PAD_VBI_OUT, as the signal it carries is actually the same as the normal video output. The difference happens at the video/VBI interface: - for VBI, only the hidden lines are streamed; - for video, the stream is usually cropped to hide the vbi lines. Acked-by:

The signal there is the same as the video output (well, except for sliced VBI, but let's simplify the model and ignore it, at least for now - as it is routed together with raw VBI). Acked-by:

The v4l2-compliance tool complains if a video doesn't start with a zero sequence number. While this shouldn't cause any real problem for apps, let's make it happier, in order to better check the v4l2-compliance differences before and after patchsets. This is actually an old issue. It is there since at least its videobuf2 conversion, e. g. changeset 3829fadc461 ("[media] em28xx: convert to videobuf2"), if VB1 wouldn't suffer from the same issue.

The a->index is not the name of the internal amux entry, but, instead a value from zero to the maximum number of audio inputs. As the actual available inputs depend on each board, build it dynamically. This is broken for a really long time. On a quick check, since at least commit 195a4ef6 ("V4L/DVB (6585): Convert em28xx to video_ioctl2") this was not implemented right.

The parameters of v4l2_ctrl_new_std_menu_items() are tricky: instead of the number of possible values, it requires the number of the maximum value. In other words, the ARRAY_SIZE() value should be decremented, otherwise it will go past the array bounds, as warned by KASAN: [ 279.839688] BUG: KASAN: global-out-of-bounds in v4l2_querymenu+0x10d/0x180 [videodev] [ 279.839709] Read of size 8 at addr ffffffffc10a4cb0 by task v4l2-compliance/16676 [ 279.839736] CPU: 1 PID: 16676 Comm: v4l2-compliance Not tainted 4.18.0-rc2+ #120 [ 279.839741] Hardware name: /NUC5i7RYB, BIOS RYBDWi35.86A.0364.2017.0511.0949 05/11/2017 [ 279.839743] Call Trace: [ 279.839758] dump_stack+0x71/0xab [ 279.839807] ? v4l2_querymenu+0x10d/0x180 [videodev] [ 279.839817] print_address_description+0x1c9/0x270 [ 279.839863] ? v4l2_querymenu+0x10d/0x180 [videodev] [ 279.839871] kasan_report+0x237/0x360 [ 279.839918] v4l2_querymenu+0x10d/0x180 [videodev] [ 279.839964] __video_do_ioctl+0x2c8/0x590 [videodev] [ 279.840011] ? copy_overflow+0x20/0x20 [videodev] [ 279.840020] ? avc_ss_reset+0xa0/0xa0 [ 279.840028] ? check_stack_object+0x21/0x60 [ 279.840036] ? __check_object_size+0xe7/0x240 [ 279.840080] video_usercopy+0xed/0x730 [videodev] [ 279.840123] ? copy_overflow+0x20/0x20 [videodev] [ 279.840167] ? v4l_enumstd+0x40/0x40 [videodev] [ 279.840177] ? __handle_mm_fault+0x9f9/0x1ba0 [ 279.840186] ? __pmd_alloc+0x2c0/0x2c0 [ 279.840193] ? __vfs_write+0xb6/0x350 [ 279.840200] ? kernel_read+0xa0/0xa0 [ 279.840244] ? video_usercopy+0x730/0x730 [videodev] [ 279.840284] v4l2_ioctl+0xa1/0xb0 [videodev] [ 279.840295] do_vfs_ioctl+0x117/0x8a0 [ 279.840303] ? selinux_file_ioctl+0x211/0x2f0 [ 279.840313] ? ioctl_preallocate+0x120/0x120 [ 279.840319] ? selinux_capable+0x20/0x20 [ 279.840332] ksys_ioctl+0x70/0x80 [ 279.840342] __x64_sys_ioctl+0x3d/0x50 [ 279.840351] do_syscall_64+0x6d/0x1c0 [ 279.840361] entry_SYSCALL_64_after_hwframe+0x44/0xa9 [ 279.840367] RIP: 0033:0x7fdfb46275d7 [ 279.840369] Code: b3 66 90 48 8b 05 b1 48 2d 00 64 c7 00 26 00 00 00 48 c7 c0 ff ff ff ff c3 66 2e 0f 1f 84 00 00 00 00 00 b8 10 00 00 00 0f 05 <48> 3d 01 f0 ff ff 73 01 c3 48 8b 0d 81 48 2d 00 f7 d8 64 89 01 48 [ 279.840474] RSP: 002b:00007ffee1179038 EFLAGS: 00000202 ORIG_RAX: 0000000000000010 [ 279.840483] RAX: ffffffffffffffda RBX: 00007ffee1179180 RCX: 00007fdfb46275d7 [ 279.840488] RDX: 00007ffee11790c0 RSI: 00000000c02c5625 RDI: 0000000000000003 [ 279.840493] RBP: 0000000000000002 R08: 0000000000000020 R09: 00000000009f0902 [ 279.840497] R10: 0000000000000000 R11: 0000000000000202 R12: 00007ffee117a5a0 [ 279.840501] R13: 00007ffee11790c0 R14: 0000000000000002 R15: 0000000000000000 [ 279.840515] The buggy address belongs to the variable: [ 279.840535] tvp5150_test_patterns+0x10/0xffffffffffffe360 [tvp5150] Fixes: c43875f6 ("[media] tvp5150: replace MEDIA_ENT_F_CONN_TEST by a control") Cc: stable@vger.kernel.org Signed-off-by:

The VIDEO_STILLPICTURE is only implemented by one driver, while VIDEO_GET_EVENT has two users in tree. In both cases, it is fairly easy to handle the compat ioctls in the native handler rather than relying on translation in fs/compat_ioctls. In effect, this means that now the drivers implement both structure layouts in both native and compat mode, but I don't see anything wrong with that. Signed-off-by:

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.

The VIDEO_GET_EVENT and VIDEO_STILLPICTURE was added back in 2005 but it never worked because the command number is wrong. Using the right command number means we have a better chance of them actually doing the right thing, though clearly nobody has ever tried it successfully. I noticed these while auditing the remaining users of compat_time_t for y2038 bugs. This one is fine in that regard, it just never did anything. Fixes: 6e87abd0 ("[DVB]: Add compat ioctl handling.")
