* V4L/DVB (13166): remove duplicate structure field initializationJulia Lawall2009-12-051-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The definition of tvaudio_tuner_ops initializes the s_tuner field twice. It appears that the second case should initialize the g_tuner field. The semantic match that finds this problem is as follows: (http://coccinelle.lip6.fr/) // <smpl> @r@ identifier I, s, fld; position p0,p; expression E; @@ struct I s =@p0 { ... .fld@p = E, ...}; @s@ identifier I, s, r.fld; position r.p0,p; expression E; @@ struct I s =@p0 { ... .fld@p = E, ...}; @script:python@ p0 << r.p0; fld << r.fld; ps << s.p; pr << r.p; @@ if int(ps[0].line)!=int(pr[0].line) or int(ps[0].column)!=int(pr[0].column): cocci.print_main(fld,p0) // </smpl> Signed-off-by: Julia Lawall <julia@diku.dk> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

* V4L/DVB (11372): v4l2: use old-style i2c API for kernels < 2.6.26 instead of ↵Hans Verkuil2009-04-071-1/+0
| | | | | | | | | | | | | | | | | | < 2.6.22 Originally the intention was to switch to the new style i2c API starting with the introduction of the API in 2.6.22. However, the i2c_new_probed_device() function has a lethal bug that wasn't fixed until 2.6.25. Or more accurately, it was only fixed in the stable series of 2.6.25 and 2.6.26. Given the fact that the new i2c API also changed starting with 2.6.26 (the addition of i2c_device_id), it is easiest to switch APIs starting with 2.6.26. This patch updates all the legacy code accordingly. Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

| | | | | | | | | s_std didn't belong in the tuner ops. Stricly speaking it should be part of the video ops, but it is used by audio and tuner devices as well, so it is more efficient to make it part of the core ops.

| | | | | | | | | | In the tvaudio_remove function del_timer_sync(&chip->wt) is called. However, chip->wt isn't always initialized depending on the type of audio chip.

* V4L/DVB (11276): tvaudio: add tda9875 support.Hans Verkuil2009-03-301-0/+132
| | | | | | | | | | | | This change allows bttv to use tvaudio for this device. Since this device has the same i2c address as the tda9874 we need to support both in the same tvaudio driver. This makes it possible for tvaudio to detect which chip is used. Originally the tda9875 was only available in the dedicated tda9875 driver, but that makes life very hard for bttv since loading tvaudio might misdetect a tda9875 as a tda9874.

| | | | | | | | | | | | The mute control depends on CHIP_HAS_INPUTSEL, so test for that first. The s/g_tuner code should check whether getmode/setmode is set at the beginning instead of filling in the struct and discovering at the end that this chip doesn't implement audiomodes after all (i.e. is a simple muxer chip).

Note that this API is not used in applications other than v4l2-dbg.cpp as it is for debugging and testing only.

* V4L/DVB (9624): CVE-2008-5033: fix OOPS on tvaudio when controlling bass/trebleMauro Carvalho Chehab2008-11-141-8/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This bug were supposed to be fixed by 5ba2f67afb02c5302b2898949ed6fc3b3d37dcf1, where a call to NULL happens. Not all tvaudio chips allow controlling bass/treble. So, the driver has a table with a flag to indicate if the chip does support it. Unfortunately, the handling of this logic were broken for a very long time (probably since the first module version). Due to that, an OOPS were generated for devices that don't support bass/treble. This were the resulting OOPS message before the patch, with debug messages enabled: tvaudio' 1-005b: VIDIOC_S_CTRL BUG: unable to handle kernel NULL pointer dereference at 00000000 IP: [<00000000>] *pde = 22fda067 *pte = 00000000 Oops: 0000 [#1] SMP Modules linked in: snd_hda_intel snd_seq_dummy snd_seq_oss snd_seq_midi_event snd_seq snd_seq_device snd_pcm_oss snd_mixer_oss snd_pcm snd_timer snd_hwdep snd soundcore tuner_simple tuner_types tea5767 tuner tvaudio bttv bridgebnep rfcomm l2cap bluetooth it87 hwmon_vid hwmon fuse sunrpc ipt_REJECT nf_conntrack_ipv4 iptable_filter ip_tables ip6t_REJECT xt_tcpudp nf_conntrack_ipv6 xt_state nf_conntrack ip6table_filter ip6_tables x_tables ipv6 dm_mirrordm_multipath dm_mod configfs videodev v4l1_compat ir_common 8139cp compat_ioctl32 v4l2_common 8139too videobuf_dma_sg videobuf_core mii btcx_risc tveeprom i915 button snd_page_alloc serio_raw drm pcspkr i2c_algo_bit i2c_i801 i2c_core iTCO_wdt iTCO_vendor_support sr_mod cdrom sg ata_generic pata_acpi ata_piix libata sd_mod scsi_mod ext3 jbdmbcache uhci_hcd ohci_hcd ehci_hcd [last unloaded: soundcore] Pid: 15413, comm: qv4l2 Not tainted (2.6.25.14-108.fc9.i686 #1) EIP: 0060:[<00000000>] EFLAGS: 00210246 CPU: 0 EIP is at 0x0 EAX: 00008000 EBX: ebd21600 ECX: e2fd9ec4 EDX: 00200046 ESI: f8c0f0c4 EDI: f8c0f0c4 EBP: e2fd9d50 ESP: e2fd9d2c DS: 007b ES: 007b FS: 00d8 GS: 0033 SS: 0068 Process qv4l2 (pid: 15413, ti=e2fd9000 task=ebe44000 task.ti=e2fd9000) Stack: f8c0c6ae e2ff2a00 00000d00 e2fd9ec4 ebc4e000 e2fd9d5c f8c0c448 00000000 f899c12a e2fd9d5c f899c154 e2fd9d68 e2fd9d80 c0560185 e2fd9d88 f8f3e1d8 f8f3e1dc ebc4e034 f8f3e18c e2fd9ec4 00000000 e2fd9d90 f899c286 c008561c Call Trace: [<f8c0c6ae>] ? chip_command+0x266/0x4b6 [tvaudio] [<f8c0c448>] ? chip_command+0x0/0x4b6 [tvaudio] [<f899c12a>] ? i2c_cmd+0x0/0x2f [i2c_core] [<f899c154>] ? i2c_cmd+0x2a/0x2f [i2c_core] [<c0560185>] ? device_for_each_child+0x21/0x49 [<f899c286>] ? i2c_clients_command+0x1c/0x1e [i2c_core] [<f8f283d8>] ? bttv_call_i2c_clients+0x14/0x16 [bttv] [<f8f23601>] ? bttv_s_ctrl+0x1bc/0x313 [bttv] [<f8f23445>] ? bttv_s_ctrl+0x0/0x313 [bttv] [<f8b6096d>] ? __video_do_ioctl+0x1f84/0x3726 [videodev] [<c05abb4e>] ? sock_aio_write+0x100/0x10d [<c041b23e>] ? kmap_atomic_prot+0x1dd/0x1df [<c043a0c9>] ? enqueue_hrtimer+0xc2/0xcd [<c04f4fa4>] ? copy_from_user+0x39/0x121 [<f8b622b9>] ? __video_ioctl2+0x1aa/0x24a [videodev] [<c04054fd>] ? do_notify_resume+0x768/0x795 [<c043c0f7>] ? getnstimeofday+0x34/0xd1 [<c0437b77>] ? autoremove_wake_function+0x0/0x33 [<f8b62368>] ? video_ioctl2+0xf/0x13 [videodev] [<c048c6f0>] ? vfs_ioctl+0x50/0x69 [<c048c942>] ? do_vfs_ioctl+0x239/0x24c [<c048c995>] ? sys_ioctl+0x40/0x5b [<c0405bf2>] ? syscall_call+0x7/0xb [<c0620000>] ? cpuid4_cache_sysfs_exit+0x3d/0x69 ======================= Code: Bad EIP value.

| | | | | | | | | | | | | | | | generic_checkmode() were called, via a callback, for some tvaudio chips. There's just one callback code used on all those boards. So, it makes no sense on keeping this as a callback. Since there were some OOPS reported on tvaudio on kerneloops.org, this patch removes this callback, adding the code at the only place were it is called: inside chip_tread. A flag were added to indicate the need for a kernel thread to set stereo mode on cards that needs it. Using this more direct approach simplifies the code, making it more robust against human errors.

* Freezer: make kernel threads nonfreezable by defaultRafael J. Wysocki2007-07-171-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, the freezer treats all tasks as freezable, except for the kernel threads that explicitly set the PF_NOFREEZE flag for themselves. This approach is problematic, since it requires every kernel thread to either set PF_NOFREEZE explicitly, or call try_to_freeze(), even if it doesn't care for the freezing of tasks at all. It seems better to only require the kernel threads that want to or need to be frozen to use some freezer-related code and to remove any freezer-related code from the other (nonfreezable) kernel threads, which is done in this patch. The patch causes all kernel threads to be nonfreezable by default (ie. to have PF_NOFREEZE set by default) and introduces the set_freezable() function that should be called by the freezable kernel threads in order to unset PF_NOFREEZE. It also makes all of the currently freezable kernel threads call set_freezable(), so it shouldn't cause any (intentional) change of behaviour to appear. Additionally, it updates documentation to describe the freezing of tasks more accurately. [akpm@linux-foundation.org: build fixes] Signed-off-by: Rafael J.

* V4L/DVB (3584): Implement V4L2_TUNER_MODE_LANG1_LANG2 audio modeHans Verkuil2006-03-241-0/+1
| | | | | | | | | | | | | Add a new audio mode V4L2_TUNER_MODE_LANG1_LANG2 (used by VIDIOC_G/S_TUNER). This mode allows the user to select both languages of a bilingual transmission, one language on the left, one on the right audio channel. If there is no bilingual transmission, or it is not supported, then this mode should act like V4L2_TUNER_MODE_STEREO. This mode is introduced for PVR-like drivers where it is useful to be able to record both languages of a bilingual broadcast.

* V4L/DVB (3582): Implement correct msp3400 input/output routingHans Verkuil2006-03-241-0/+24
| | | | | | | | | | - implement VIDIOC_INT_S_AUDIO_ROUTING for msp3400 and tvaudio - use the new command in bttv, pvrusb2 and em28xx. - remove the now obsolete MSP_SET_MATRIX from msp3400 (yeah!) - remove the obsolete VIDIOC_S_AUDIO from msp3400.

* V4L/DVB (3577): Cleanup audio input handlingHans Verkuil2006-03-241-19/+48
| | | | | | | | | | | | | | | | | | | | | | Cleanup audio input handling in bttv and tvaudio: - inputs were specified that were never used - mute was handled as a special input which led to confusing code - confusing naming made it difficult to see if the setting was for i2c or gpio. The old audiochip.h input names moved to tvaudio.h. Currently this is used both by tvaudio and msp3400 until the msp3400 implements the new msp3400-specific inputs. Detect in bttv the tvaudio and msp3400 i2c clients and use these client pointers to set the inputs directly instead of broadcasting the command. Removed AUDC_SET_INPUT. Now replaced by VIDIOC_S_AUDIO. This will be replaced again later by the new ROUTING commands. Removed VIDIOC_G_AUDIO implementations in i2c drivers: this command is a user level command and not to be used internally. It wasn't called at all anyway.

| | | | | | | I2C_foo were used for some i2c addresses. Bad, since those constants could mean other i2c chip things. Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
