2008-12-01em28xx: remove backward compat macro added on a previous fixMauro Carvalho Chehab
commit 50f3beb50abe0cc0228363af804e50e710b3e5b0 fixed em28xx-alsa locking schema. However, a backport macro was kept. This patch removes the macro, since it is not needed for the module compilation against upstream. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

The previous subdriver protection against rmmod was done via the file operations table in the device descriptor. On device disconnection while streaming, the device structure was freed at close time, and the module_put still used the module name in the freed area.

2008-11-20V4L/DVB (9668): em28xx: fix a race condition with haldMauro Carvalho Chehab
Newer versions of hald tries to open it to call QUERYCAP. Due to the lack of a proper locking, it is possible to open the device before it finishes initialization. This patch adds a lock to avoid this risk, and to protect the list of em28xx devices. While here, remove the uneeded BKL lock. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

Now that we have a polling task for IR, there's a race condition, since IR can be polling while other operations are being doing.

2008-11-20V4L/DVB (9646): em28xx: avoid allocating/dealocating memory on every control urbMauro Carvalho Chehab
Before this patch, every register setup on em28xx were dynamically allocating a temporary buffer for control URB's to be handled. To avoid this ping-pong, use, instead a pre-allocated buffer. Also, be sure that read control URB's also use the buffer, instead of relying on a stack buffer. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

2008-11-16V4L/DVB (9634): Make sure the i2c gate is open before powering down tunerDevin Heitmueller
It is not safe to assume that the i2c gate will be open before issuing the command to power down the tuner. In fact, many demods only open the gate long enough to issue the tuning command.

2008-11-14V4L/DVB (9624): CVE-2008-5033: fix OOPS on tvaudio when controlling bass/trebleMauro Carvalho Chehab
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.

2008-11-14V4L/DVB (9618): tvaudio: add additional logic to avoid OOPSMauro Carvalho Chehab
This patch checks for volume, bass, treble, set mode and get mode callbacks before actually enabling the code that would use them. Instead of aborting the driver for load, this patch will allow it to load with a reduced number of functionatities. This prevents OOPS if some board entry is missing a needed callback.

2008-11-14V4L/DVB (9617): tvtime: remove generic_checkmode callbackMauro Carvalho Chehab
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.
