Package: src:linux
Version: 6.1.4-1
Severity: normal
Dear Maintainer,
*** Reporter, please consider answering these questions, where appropriate ***
* What led up to the situation?
This was triggered when trying to capture video via a bt878 card using the
https://github.com/ali1234/vhs-teletext script. Note 'xawtv' is working
fine, so the card is generally happy.
* What exactly did you do (or not do) that was effective (or
ineffective)?
I ran 'teletext record -d /dev/vbi0 > capture.vbi' from the above package
that triggers a read from vbi0; an strace shows:
[pid 6466] read(3, 0x27feb20, 65536) = -1 ENOMEM (Cannot allocate memory)
and the WARN_ON in the dmesg
* What was the outcome of this action?
a WARNING in the dmesg, see below; and the python script backtraced
with apparently an -ENOMEM; but there's plenty of RAM:
dg@major:~/vhs-teletext$ free -m
total used free shared buff/cache available
Mem: 7937 789 2963 2 4484 7147
Swap: 974 0 974
* What outcome did you expect instead?
Happy gathered video.

Version: 6.1.4-1
Severity: normal
Dear Maintainer,
*** Reporter, please consider answering these questions, where appropriate ***
* What led up to the situation?
This was triggered when trying to capture video via a bt878 card using the
https://github.com/ali1234/vhs-teletext script. Note 'xawtv' is working
fine, so the card is generally happy.
* What exactly did you do (or not do) that was effective (or
ineffective)?
I ran 'teletext record -d /dev/vbi0 > capture.vbi' from the above package
that triggers a read from vbi0; an strace shows:
[pid 6466] read(3, 0x27feb20, 65536) = -1 ENOMEM (Cannot allocate memory)
and the WARN_ON in the dmesg
* What was the outcome of this action?
a WARNING in the dmesg, see below; and the python script backtraced
with apparently an -ENOMEM; but there's plenty of RAM:
dg@major:~/vhs-teletext$ free -m
total used free shared buff/cache available
Mem: 7937 789 2963 2 4484 7147
Swap: 974 0 974
* What outcome did you expect instead?
Happy gathered video.

That 5.18 failure is a bit different, but the backtrace is similar;
somewhere between 5.18 it's changed from a BUG to a WARN but
back in 5.15 it just worked.

I built upstream kernels 5.18.0 and 6.1.0 and both of them work for me.
Which makes life much more painful to find.

This is IOMMU related.
Upstream 6.1 and 5.18 *do* exhibit the bug, but only with intel_iommu=on
where as Debian seems to default it to on.

Upstream 5.17 works
Upstream 5.18 fails
(with intel_iommu=on)
Let the bisect begin.

dma-mapping: remove CONFIG_DMA_REMAP
That sounds like a believable cause given that it's IOMMU related
and device related.

Note that the oops at this bisect point is messier than on the newer
kernels; the newer kernels hit a WARN in __vmap_pages_range_noflush, where
as at this point it slams into a BUG, but the rest of the backtrace is similar;

If you're 'penguin42' on IRC, then I'd suggest to present your findings to
io...@lists.linux.dev as both the author and the reviewer are highly likely
subscribed to that list.
scripts/get_maintainer.pl drivers/iommu/dma-iommu.c
scripts/get_maintainer.pl kernel/dma/Makefile
list them both and both results have also that ML in their result.

Yep, will do; I'm just going to try a 6.2rc as well just in case it's
got fixed very recently, and have a poke about in case I can see
any obvious cause now I know the change that triggered it.
I'll include the linux-media list as well since it's just as likely
that it's a fault on the v4l/bttv driver.

It's a bit messy...
a) The patch I bisected to is not the root cause of the bug; it just
triggers a ~9 year old bug in the v4l code - so this patch isn't going
to get changed.
b) The ~9 year old bug is in a particularly hairy piece of memory management
code in v4l that I doubt anyone is going to fix.
c) The plan is all the drivers using that API are to either be retired
or rewritten using a new API; that's already been done for some of the
drivers and the bttv one is a few months out. I'm not sure that's
any use to this version of Debian though.
d) The work arounds are:
1) Disable iommu
2) some v4l tools can use an mmap interface rather than the read(2)
interface; that seems to be OK.

Also reading the upstream conversation, that seems like a good summary :)

I could be wrong (ofc), but I doubt this issue will be fixed in kernel 6.1
which is planned to be Bookworm's kernel.
What you could do is test any patch(es) they put out and provide feedback on
those and if you find that the patch(es) fixes the/your issue, you could
consider providing a "Tested-By: yourname <your.email>" which can have a
positive effect on the maintainer accepting the patch from which it then can
procede further up the chain to Linus.
When it does end up in Linus' tree and it would need to have a new Kconfig
option enabled in Debian's kernel, feel free to request that.
I think IOMMU is a really good thing, so disabling that does not sound ideal,
but it could be an acceptable workaround (for now).
If you want to run Bookworm on your system, you'd probably have to wait till a
suitable Backports kernel becomes available. If you go for Trixie, you should
get (in time) the proper fix by just upgrading.
Thanks for all the investigative work and bringing it to upstream :-)

This looks like it's fixed in 6.6, I think they had a major rewrite
in there.
It's a conversion to vb2 in the series starting with
d1846d72587e9241e73a18da14a325b43700013b
There are a couple of minor oddities with that
(they list the sequence cost the bttv had) but that's relatively minor.
in there.

As well as the fixes in 6.6, we also need this patchup series here:
https://lore.kernel.org/linux-media/ZWibhE350L3BTRK8@gallifrey/T/#t
These seem to make it pretty nicely.

Excellent :) I saw they had "Fixes:" tags, which normally means they'll
get backported to older kernel series like 6.6.
