[PATCH net-next 0/2] Introduce generic 6LoWPAN branch

[PATCH net-next 0/2] Introduce generic 6LoWPAN branch

[Alexander Aring]

Hi,

this patch series add a new branch "net/6lowpan" for generic 6LoWPAN code.

Since commit 8df8c56a5abc70af5862aa7cac2875aeeb17a42b ("6lowpan: Moving
generic compression code into 6lowpan_iphc.c") the IPHC compression is shared
between bluetooth 6LoWPAN and IEEE 802.15.4 6LoWPAN. The new 6LoWPAN directory
will contain generic code for 6LoWPAN and futhermore 6LoWPAN upper layer
protocols.

The shared code between bluetooth and 802.15.4 should be review from both
communities. The current behaviour is that get_maintainers.pl returns the
IEEE 802.15.4 community only.


I request a new mailinglist for the IEEE 802.15.4 subsystem at vger but I didn't
get a response now so I add the current sourceforge IEEE 802.15.4 mailinglist to
the MAINTAINERS file. I will update them soon.

- Alex

[PATCH net-next 1/2] 6lowpan: introduce new net/6lowpan directory

[Alexander Aring]

This patch moves generic code which is used by bluetooth and ieee802154
6lowpan to a new net/6lowpan directory. This directory contains generic
6LoWPAN code which is shared between bluetooth and ieee802154 MAC-Layer.

This is the IPHC - "IPv6 Header Compression" format at the moment. Which
is described by RFC 6282 [0]. The BLTE 6LoWPAN draft describes that the
IPHC is the same format like IEEE 802.15.4, see [1].

Futuremore we can put more code into this directory which is shared
between BLTE and IEEE 802.15.4 6LoWPAN like RFC 6775 or the routing
protocol RPL RFC 6550.

To avoid naming conflicts I renamed 6lowpan-y to ieee802154_6lowpan-y
in net/ieee802154/Makefile.

this will conflict with our changes in wireless-next tree. We converted out 6LoWPAN support into a separate module.

Dave, can we take this through bluetooth-next and wireless-next trees?

oops, sorry I didn't check on this. I simple based it on net-next,
because the patch series adds a new branch.



btw. we need to talk about who branch will commit changes to iphc code
to avoid conflicts.

a few years back we decided to merge bluetooth-next via John's wireless-next tree so that any interaction with 802.11 and Bluetooth can be sorted out in John's tree. We are now also merging NFC into the wireless-next tree.

So it might be a good idea to include the 6LoWPAN parts into the wireless-next tree as well. If there are conflicts with 802.15.4, maybe that should also go through his trees.

If you want I can also take the net/6lowpan stuff through bluetooth-next tree.

Marcel

Please take this stuff via the bluetooth/wireless trees to avoid the

Ok. I am maintainer since three days ago and I need some time to setup
my infrastructure, then I will ask him. At the end I need to update the
MAINTAINERS file to the new infrastructure.

Yes, please Marcel. This is one file at the moment. I have in my local
branch also some patches (most of them use IPv6 API for address scopes
instead using the self builded macros). There is also a issue with error
handling which should be a long overdue fix. You will get some patches
for these issues in the next days.


If we have more implementation stuff in there, then we should setup a
own 6lowpan mailinglist maybe. At the moment this is fine.

Thanks.

I resolved the conflict locally in bluetooth-next and applied both of your patches to bluetooth-next tree.

ok. Thanks.

I notice there is a patch in net-next for the old file
4710d806fcb825156e0a7b3a81104915c5e90f5d ("6lowpan: mac802154: fix coding
style issues").

It's not in bluetooth-next currently and the movement patch should not
occur any conflicts (I think). But I can't send you patches until this
is in bluetooth-next.

I wait until the next sync of bluetooth-next with net-next and you should not
apply any patches to "net/6lowpan/iphc.c" until that.

I did a quick local test merge of bluetooth-next into net-next and git does the correct resolution (as far as I can tell) here. So this should not be a problem.

If they are not urgent, then lets wait until we merged everything into net-next.

[PATCH net-next 2/2] MAINTAINERS: add net/6lowpan/ maintainer entry

[Alexander Aring]

This patch add a maintainer entry for "net/6lowpan". Also add the current
IEEE 802.15.4 mailing list and bluetooth mailinglist to this branch,
because this code is shared between them.
