Commit 6487a9d was an attempt some buffer head leaks in an ENOSPC
error path, but in some cases it actually results in an excess ENOSPC,
as shown above.  Fixing this means cleaning up who is responsible for
releasing the buffer heads from the callee to the caller of
add_dirent_to_buf().

Since that's a relatively complex change, and we're late in the rcX
development cycle, I'm reverting this now, and holding back a more
complete fix until after 2.6.32 ships.  We've lived with this
buffer_head leak on ENOSPC in ext3 and ext4 for a very long time; a
few more months won't kill us.

This fixes a kernel oops reported by Markus Trippelsdorf in the email
titled "[NILFS users] kernel Oops while running nilfs_cleanerd".

The oops was caused by a bug of error path in
nilfs_ioctl_move_blocks() function, which was inlined in
nilfs_ioctl_clean_segments().

nilfs_ioctl_move_blocks checks duplication of blocks which will be
moved in garbage collection.  But, the check should have be done
within nilfs_ioctl_move_inode_block() to prevent list corruption among
buffers storing the target blocks.

To fix the kernel oops, this moves forward the duplication check
before the list insertion.

I also tested this for stable trees [2.6.30, 2.6.31].

V4L/DVB (13170): bttv: Fix reversed polarity error when switching video standard

The bttv driver function which handles switching of the video standard
(set_tvnorm() in bttv-driver.c) includes a check which can optionally
also reset the cropping configuration to a default value.  It is
"optional" based on a comparison of the cropcap parameters of the
previous vs the newly requested video standard.  The comparison is
being done with a memcmp(), a function which only returns a true value
if the comparison actually fails.

This if-statement appears to have been written to assume wrong
memcmp() semantics.  That is, it was re-initializing the cropping
configuration only if the new video standard did NOT have different
cropcap values.  That doesn't make any sense.  One definitely should
reset things if the cropcap parameters are different - if there's any
comparison to made at all.

The effect of this problem was that a transition from, say, PAL to
NTSC would leave in place old cropping setup that made sense for the
PAL geometry but not for NTSC.  If the application doesn't care about
cropping it also won't try to reset the cropping configuration,
resulting in an improperly cropped video frame.  In the case I was
testing this actually caused black video frames to be displayed.

Another interesting effect of this bug is that if one does something
which does NOT change the video standard and this function is run,
then the cropping setup gets reset anyway - again because of the
backwards comparison.  It turns out that just running anything which
merely opens and closes the video device node (e.g. v4l-info) will
cause this to happen.  One can argue that simply opening the device
node and not doing anything to it should not mess with any of its
state - but because of this behavior, any TV app which does such
things (e.g. xawtv) probably therefore doesn't see the problem.

The solution is to fix the sense of the if-statement.  It's easy to
see how this mistake could have been made given how memcmp() works.
The patch is therefore removal of a single "!" character from the
if-statement in set_tvnorm in bttv-driver.c.

12 years agoV4L/DVB (13169): bttv: Fix potential out-of-order field processing
Mike Isely [Mon, 21 Sep 2009 15:09:08 +0000 (12:09 -0300)]
V4L/DVB (13169): bttv: Fix potential out-of-order field processing

There is a subtle interaction in the bttv driver which can result in
fields being repeatedly processed out of order.  This is a problem
specifically when running in V4L2_FIELD_ALTERNATE mode (probably the
most common case).

1. The determination of which fields are associated with which buffers
happens in videobuf, before the bttv driver gets a chance to queue the
corresponding DMA.  Thus by the point when the DMA is queued for a
given buffer, the algorithm has to do the queuing based on the
buffer's already assigned field type - not based on which field is
"next" in the video stream.

2. The driver normally tries to queue both the top and bottom fields
at the same time (see bttv_irq_next_video()).  It tries to sort out
top vs bottom by looking at the field type for the next 2 available
buffers and assigning them appropriately.

3. However the bttv driver *always* actually processes the top field
first.  There's even an interrupt set aside for specifically
recognizing when the top field has been processed so that it can be
marked done even while the bottom field is still being DMAed.

Given all of the above, if one gets into a situation where
bttv_irq_next_video() gets entered when the first available buffer has
been pre-associated as a bottom field, then the function is going to
process the buffers out of order.  That first available buffer will be
put into the bottom field slot and the buffer after that will be put
into the top field slot.  Problem is, since the top field is always
processed first by the driver, then that second buffer (the one after
the first available buffer) will be the first one to be finished.
Because of the strict fifo handling of all video buffers, then that
top field won't be seen by the app until after the bottom field is
also processed.  Worse still, the app will get back the
chronologically later bottom field first, *before* the top field is
received.  The buffer's timestamps will even be backwards.

While not fatal to most TV apps, this behavior can subtlely degrade
userspace deinterlacing (probably will cause jitter).  That's probably
why it has gone unnoticed.  But it will also cause serious problems if
the app in question discards all but the latest received buffer (a
latency minimizing tactic) - causing one field to only ever be
displayed since the other is now always late.  Unfortunately once you
get into this state, you're stuck this way - because having consumed
two buffers, now the next time around the "first" available buffer
will again be a bottom field and the same thing happens.

How can we get into this state?  In a perfect world, where there's
always a few free buffers queued to the driver, it should be
impossible.  However if something disrupts streaming, e.g. if the
userspace app can't queue free buffers fast enough for a moment due
perhaps to a CPU scheduling glitch, then the driver can get
momentarily starved and some number of fields will be dropped.  That's
OK.  But if an odd number of fields get dropped, then that "first"
available buffer might be the bottom field and now we're stuck...

This patch fixes that problem by deliberately only setting up a single
field for one frame if we don't get a top field as the first available
buffer.  By purposely skipping the other field, then we only handle a
single buffer thus bringing things back into proper sync (i.e. top
field first) for the next frame.  To do this we just drop the few
lines in bttv_irq_next_video() that attempt to set up the second
buffer when that second buffer isn't for the bottom field.

This is definitely a problem in when in V4L2_FIELD_ALTERNATE mode.  In
the other modes this change either has no effect or doesn't harm
things any further anyway.

V4L/DVB (13109): tda18271: fix signedness issue in tda18271_rf_tracking_filters_init

While having tda18271 module set with debug=17 (cal & info prints) and
cal=0 (delay calibration process until first use) - I discovered that
during the calibration process, if the frequency test for 69750000
returned a bcal of 0 (see tda18721-fe.c in tda18271_powerscan func) that
the tuner wouldn't be able to pickup any of the frequencies in the range
(all the other frequencies bands returned bcal=1).  I spent some time
going over the code and the NXP's tda18271 spec (ver.4 of it i think) and
adding a lot of debug prints and walking/stepping through the calibration
process.  I found that when the powerscan fails to find a frequency, the
rf calibration is not run and the default value is supposed to be used in
its place (pulled from the RF_CAL_map table) - but something was getting
goofed up there.

Now, my c coding skills are very rusty, but i think root of the problem is
a signedness issue with the math operation for calculating the rf_a1 and
rf_a2 values in tda18271_rf_tracking_filters_init func, which results in
values like 20648 for rf_a1 (when it should probably have a value like 0,
or so slightly negative that it should be zero - this bad value for rf_a1
would in turn makes the approx calc within
tda18271c2_rf_tracking_filters_correction go out of whack).  The simplest
solution i found was to explicitly convert the signedness of the
denominator to avoid the implicit conversion.  The values placed into the
u32 rf_freq array should never exceed about 900mhz, so i think the s32 max
value shouldn't be an issue in this case.

I've tested it out a little, and even when i get a bcal=0 with the
modified code, the default calibration value gets used, rf_a1 is zero, and
the tuner seems to lock on the stream and mythtv seems to play it fine.

Now this patch disables CORB/RIRB initialization when the single_cmd

ipip: Fix handling of DF packets when pmtudisc is OFF

RFC 2003 requires the outer header to have DF set if DF is set
on the inner header, even when PMTU discovery is off for the
tunnel.  Our implementation does exactly that.

For this to work properly the IPIP gateway also needs to engate
in PMTU when the inner DF bit is set.  As otherwise the original
host would not be able to carry out its PMTU successfully since
part of the path is only visible to the gateway.

Unfortunately when the tunnel PMTU discovery setting is off, we
do not collect the necessary soft state, resulting in blackholes
when the original host tries to perform PMTU discovery.

This problem is not reproducible on the IPIP gateway itself as
the inner packet usually has skb->local_df set.  This is not
correctly cleared (an unrelated bug) when the packet passes
through the tunnel, which allows fragmentation to occur.  For
hosts behind the IPIP gateway it is readily visible with a simple
ping.

This patch fixes the problem by performing PMTU discovery for
all packets with the inner DF bit set, regardless of the PMTU
discovery setting on the tunnel itself.
