I'm announcing the release of the 3.18.102 kernel.
All users of the 3.18 kernel series must upgrade.
The updated 3.18.y git tree can be found at:
git://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable.git linux-3.18.y
and can be browsed at the normal kernel.org git web browser:
http://git.kernel.org/?p=linux/kernel/git/stable/linux-stable.git;a=summary
thanks,
greg k-h

That is correct.
> Any plan to apply the series?
Do you have a backported version of this series that will apply to that
kernel tree? If so, I'll be glad to apply it but I'm pretty sure the
reason I did not apply them was because they did not apply correctly.
Also, are you even sure you need these patches for 3.18.y? Do you have
a v4l2 device that relies on these fixes?
thanks,

I dit not do it myself. I just checked the series is applied on other
stable trees.

I've just expected A-34624167 is also fixed from other ARM64 devices
based on 3.18.y.

Yes because those trees needed that series. Also, 3.18.y is barely
alive, if you need to rely on this kernel tree for a device, you are
already maintaining it yourself, right?

What is "A-34624167"?
Again, do you have a v4l2 device that uses this interface that needs
these fixes? In looking at the 3.18.y tree, that's a very small list of
devices that are very old and rare from what I remember.
And if you do have such a device, can you just move to 4.4.y instead?
If you need these patches on 3.18.y, I'll be glad to apply them if you
provide a backported series that you can verify work for you.

Backporting it from Kernel 4.1 is quite simple. Just two patches
have trivial conflicts.
I did a quick backport at:
https://git.linuxtv.org/mchehab/experimental.git/log/?h=v3.18.102%2bCVE
Please notice that I didn't test it yet.
Will build such Kernel and see how it behaves with compat32.
If it works fine, I'll submit for stable.

Mauro

Hi Seung-Woo,
I did some tests here with the vivid driver and v4l2-compliance tool.
I had to apply a few fixes on the top of the 4.1 patchset.
With those fixes, compat32 is working fine with Kernel 3.18.102 on my
test environment.
Feel free to use it on your tree. The patches are under the
top of 3.18.102, on my development tree:
https://git.linuxtv.org/mchehab/experimental.git/log/?h=v3.18.102%2bCVE
It should be noticed that 5 other patches are required for it to
work at Kernel 3.18 and to make v4l2-compliance to produce the same
results on both 32 bits and 64 bits version.
Those two are backports from upstream and contains some control fixes
applied at Kernel 4.1:
1663cf48e2eb media: media/v4l2-ctrls: volatiles should not generate CH_VALUE
d53d22eb0ea4 media: v4l2-ctrls: fix sparse warning
This patch fix an extra issue with compat32 code that is specific to
Kernel 3.18, and backports a change that also happened upstream:
2ba950543618 media: v4l2-compat-ioctl32: use compat_u64 for video standard
Those 2 patches are required to fix some issues that I suspect that also
affect upstream patches:
acf19bbe76c5 media: v4l2-compat-ioctl32: initialize a reserved field
ccaf872a9873 media: v4l2-compat-ioctl32: don't oops on overlay
However, I didn't test with other Kernel versions yet. Such patches should
go through the usual review at media ML.
After having them reviewed and applied upstream (if needed), I'll submit
the entire series for Greg to pick for Kernel 3.18.
Regards,
Mauro
