Pawel Osciak [Wed, 28 Apr 2010 07:05:21 +0000 (04:05 -0300)]
V4L/DVB: Add a new ERROR flag for DQBUF after recoverable streaming errors

This flag is intended to indicate streaming errors, which might have
resulted in corrupted video data in the buffer, but the buffer can still
be reused and streaming may continue.

Setting this flag and returning 0 is different from returning EIO. The
latter should now indicate more serious (unrecoverable) errors.

This patch also solves a problem with the ioctl handling code in
vl42-ioctl.c, which does not copy buffer identification data back to the
userspace when EIO is returned, so there is no way for applications
to discover on which buffer the operation failed in such cases.

core->board.input[] for an input with a type of CX88_VMUX_DVB, and if
it does not find one, the index is simply set to zero.
The change may not have much effect, though, since it appears the only

Changing a video standard takes a long time to happen on tm6000, since it
needs to load another firmware, and the i2c implementation on this device
is really slow. When the driver tries to change the video standard, a
kernel panic is produced:

BUG: unable to handle kernel NULL pointer dereference at 0000000000000008
IP: [<ffffffffa0c7b48a>] tm6000_irq_callback+0x57f/0xac2 [tm6000]
...
Kernel panic - not syncing: Fatal exception in interrupt

By inspecting it with gdb:

(gdb) list *tm6000_irq_callback+0x57f
0x348a is in tm6000_irq_callback (drivers/staging/tm6000/tm6000-video.c:202).
197             /* FIXME: move to tm6000-isoc */
198             static int last_line = -2, start_line = -2, last_field = -2;
199
200             /* FIXME: this is the hardcoded window size
201              */
202             unsigned int linewidth = (*buf)->vb.width << 1;
203
204             if (!dev->isoc_ctl.cmd) {
205                     c = (header >> 24) & 0xff;
206

Clearly, it was the trial to access *buf, at line 202 that caused the
Panic.

As ioctl is serialized, While S_STD is handled,QBUF/DQBUF won't be called.
So, the driver will run out of the buffers, and *buf will become NULL.

As, on tm6000, the same URB can contain more than one video buffer, it is
likely to hit a condition where no new buffer is available whily copying
the streams. The fix is to leave the URB copy loop, if there's no more buffers
are available.

The same bug could also be produced by an application that is not fast enough
to request new video buffers.

The same bug were reported by Bee Hock Goh <beehock@gmail.com>.
