Subject: pull request: batman-adv 2014-01-09
Hello David,
this is a batch of patches intended for net-next/linux-3.14.
Here we start with patches 1, 2 and 3 that are minor cleanups:
- fix a typ0 in a header guard define
- substitute the FSF address with the URL in every file (checkpatch still
complains about the text I used, but this is what the rest of the networking
code is doing)
- minor optimisation of ntohl usage
Then we have patch 4 that improves the bat-GW selection feature by deselecting
the current GW on client mode deactivation. This allows userspace to get a
meaningful uevent on a further client mode reactivation.
Patches 5 and 6 are other minor refactorings:
- a function renaming (gw_deselect() -> gw_reselect()) to better reflect its
behaviour
- remove parenthesis around return expressions
Patch 7 is yet another improvement to the bat-GW feature: now all the DHCP
packets are sent via bat-unicast messages. With this we achieves to goals:
1) the DHCP protocol becomes even more reliable in sparse wireless mesh
networks, where broadcast packets do not always make their way through
2) the broadcast overhead due to DHCP packets in dense wireless networks
is now reduced as we only use unicasts.
In the end patches from 8 to 13 implement a new feature: the Extended
Isolation (which is basically it is an extension of the already existing AP
Isolation concept).
This new mechanism allows the user to prevent communications from a generic
client A to a generic client B (located in two different point of the mesh
network) based on the value of the skb->mark field. This can be seen as a first
step towards a netfilter integration in a mesh-wide environment.
For more documentation about this new mechanism, please read [1].
Please pull or let me know of any problem!
Thanks a lot,
Antonio

p.s. thanks for notifying me the merge of net into net-next! In this way I
avoided you to deal with some ugly merge conflicts :)

batman-adv: set the isolation mark in the skb if needed (2014-01-08 20:49:46 +0100)
----------------------------------------------------------------
Included changes:
- substitute FSF address with URL
- deselect current bat-GW when GW-client mode gets deactivated
- send every DHCP packet using bat-unicast messages when GW-client mode is
enabled
- implement the Extended Isolation mechanism (it is an enhancement of the
already existing batman-AP-isolation). This mechanism allows the user to drop
packets exchanged by selected clients by using netfilter marks.
- fix typ0 in header guard
- minor code cleanups
----------------------------------------------------------------
Antonio Quartulli (13):
batman-adv: properly rename define in distributed arp table header file
batman-adv: don't switch byte order too often if not needed
batman-adv: remove FSF address from GPL disclaimer
batman-adv: deselect current GW on client mode switch off
batman-adv: rename gw_deselect() to gw_reselect()
batman-adv: remove parenthesis from return statements
batman-adv: send every DHCP packet as bat-unicast
batman-adv: add isolation_mark sysfs attribute
batman-adv: mark a local client as isolated when needed
batman-adv: print the new BATADV_TT_CLIENT_ISOLA flag
batman-adv: extend the ap_isolation mechanism
batman-adv: create helper function to get AP isolation status
batman-adv: set the isolation mark in the skb if needed
