| * em28xx: remove backward compat macro added on a previous fixMauro Carvalho Chehab2008-12-01
| | | | | | | | | | | | | | | | | | | | 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>

| | | | | | | | | | | | | | | | | | | | | | | | It is not safe to assume that the i2c gate will be open before issuing the command to power down the tuner.

* V4L/DVB (9624): CVE-2008-5033: fix OOPS on tvaudio when controlling bass/trebleMauro Carvalho Chehab2008-11-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

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.
