Hi,
I improved the patchset a bit more:
* batctl crash fixed
* batctl man page update
* crash in find_routers()
* cash when forwarding broadcasts
* one forgotten global variable eliminated
Thanks for the (off-list) feedback I received so far. I will submit these
patches if nobody objects during the coming days.
Regards,
Marek

This patch replaces the static bat0 interface with a dynamic/abstracted
approach. It is now possible to create multiple batX interfaces by
assigning hard interfaces to them. Each batX interface acts as an
independent mesh network. A soft interface is removed once no hard
interface references it any longer.

2 siblings, 0 replies; 6+ messages in thread
From: Marek Lindner @ 2010-07-24 15:16 UTC (permalink / raw)
To: b.a.t.m.a.n; +Cc: Marek Lindner
This patch removes all remaining global variables and includes the
necessary bits into the bat_priv structure. It is the last
remaining piece to allow multiple concurrent mesh clouds on the
same device.
A few global variables have been rendered obsolete during the process
and have been removed entirely.

From: Marek Lindner @ 2010-07-24 15:16 UTC (permalink / raw)
To: b.a.t.m.a.n; +Cc: Marek Lindner
Since the batman-adv kernel supports multiple mesh clouds batctl comes
with a new optional parameter '-m' which allows to specify the mesh
cloud a specific command shall be applied to. It defaults to 'bat0'
which guarantees compatibility with the previous behaviour.

* [B.A.T.M.A.N.] [PATCH 3/3] batctl: support for multiple mesh clouds
2010-07-11 18:00 [B.A.T.M.A.N.] multiple mesh clouds (2) Marek Lindner
@ 2010-07-11 18:01 ` Marek Lindner
0 siblings, 0 replies; 6+ messages in thread
From: Marek Lindner @ 2010-07-11 18:01 UTC (permalink / raw)
To: b.a.t.m.a.n; +Cc: Marek Lindner
Since the batman-adv kernel supports multiple mesh clouds batctl comes
with a new optional parameter '-m' which allows to specify the mesh
cloud a specific command shall be applied to. It defaults to 'bat0'
which guarantees compatibility with the previous behaviour.

* [B.A.T.M.A.N.] [PATCH 3/3] batctl: support for multiple mesh clouds
2010-07-10 14:06 [B.A.T.M.A.N.] " Marek Lindner
@ 2010-07-10 14:06 ` Marek Lindner

From: Marek Lindner @ 2010-07-10 14:06 UTC (permalink / raw)
To: b.a.t.m.a.n; +Cc: Marek Lindner
Since the batman-adv kernel supports multiple mesh clouds batctl comes
with a new optional parameter '-m' which allows to specify the mesh
cloud a specific command shall be applied to. It defaults to 'bat0'
which guarantees compatibility with the previous behaviour.
