Hi,
here are patches targetted for 2.6.36. These replace all patches send to you
for 2.6.36 in mails following
1275850985-27105-1-git-send-email-sven.eckelmann@gmx.de due to conflicting
changes for 2.6.35 from Dan Carpenter and Javier Martinez Canillas.
There are also 3 new patches (7-9).
Maybe we could time our patches for upcoming kernels. Is there a specific point
where you start to insert new patches for the next kernel into staging-next?
Currently we know that it should be at least a week before a kernel is released
to allow other people to test changes in linux-next.
Best regards,
Sven

The hardif_attr and the bat_attr struct share the same attributes,
hence it is not necessary to specify 2 different structs.

batctl uses /dev/batman-adv to send special batman-adv icmp packets to
other nodes in the mesh. To get it working with multiple batX devices we
must ensure that every mesh device can have their own socket which is
used to inject those packets in exactly one mesh.
The current implementation still doesn't allow to use complete separated
meshes as we rely on structures which are not part of the private data
of a batman device.

From: Sven Eckelmann @ 2010-06-06 19:28 UTC (permalink / raw)
To: gregkh, b.a.t.m.a.n
Files which represent more than a single attribute aren't allowed in
sysfs. As we have some files which aren't essential and are lists or
tables aggregated from data from different places inside batman-adv, we
must place them in a filesystem without such a restriction.

batman-adv is receiving and sending the packets of its own ether type
on a very early/low level. Therefore we need to add explicit hooks to
give netfilter/ebtables a chance to filter them.

vis_interval does not neccesarily needs to be a variable, as there is
no way to change it anyway (and probably no need to). We can therefore
remove yet another global variable.
Thanks Marek for pointing this out.

This patch doesn't apply, I get the following error:
patching file drivers/staging/batman-adv/Makefile
patching file drivers/staging/batman-adv/bat_debugfs.c
patching file drivers/staging/batman-adv/bat_debugfs.h
patching file drivers/staging/batman-adv/device.c
Reversed (or previously applied) patch detected! Assume -R? [n] ^C
Any ideas?

I could not apply the following patches for some odd reason:
2, 3, 4, 7, 9
I applied the others.
So you might want to resync on the my staging-next tree and see what
went wrong. Does it have something to do with the other batman patches
I have in my staging.current tree to go to Linus?
odd,

You forgot(?) to apply the patches
* Staging: batman-adv: return -EFAULT on copy_to_user errors
* Staging: batman-adv: fix function prototype
With those patches it works like a charm. And at least the second one is
extreme important for 2.6.35.
You said (or at least a script use by you) that you have them in
http://www.kernel.org/pub/linux/kernel/people/gregkh/gregkh-2.6/patches/ ...
if that is some kind of aggregation from staging.current then yes - we depend
on them. That was the reason why I had to resent all the patches (that's why
there is a "renewed" in the title) - to allow you to apply them on top of
those other two patches.
I wanted to sent you some more patches a hour or two ago... had to be delayed
to find out what is going wrong here. I will sent them those need also the
patches mentioned above.
Let's hope that this explains everything. :)
thanks,
Sven

Ah, no, I didn't forget, they are just in a different branch.
Sorry, I didn't think about that one. I'll go merge those patches into
this branch as well, so as to make it all work out properly. Git will
handle the fact that they show up twice just fine when it comes to
merging things.
Sorry about this, I'll resolve it all on my end on Monday, and thanks
for resending everything.
