commit 4e820e72db584e39c7d8699eb359d9a94eb837e3
Author: Antonio Quartulli <antonio(a)open-mesh.com>
Date: Mon Nov 4 20:59:41 2013 +0100
batman-adv: rename gw_deselect() to gw_reselect()
The function batadv_gw_deselect() is actually not deselecting
anything. It is just informing the GW code to perform a
re-election procedure when possible.
The current gateway is not being touched at all and therefore
the name of this function is rather misleading.
Rename it to batadv_gw_reselect() to batadv_gw_reselect()
to make its behaviour easier to grasp.

batman-adv: send every DHCP packet as bat-unicast
In different situations it is possible that the DHCP server
or client uses broadcast Ethernet frames to send messages
to each other. The GW component in batman-adv takes care of
using bat-unicast packets to bring broadcast DHCP
Discover/Requests to the "best" server.
On the way back the DHCP server usually sends unicasts,
but upon client request it may decide to use broadcasts as
well.
This patch improves the GW component so that it now snoops
and sends as unicast all the DHCP packets, no matter if they
were generated by a DHCP server or client.

commit c42edfe382fee1c2c74550a5a3cbf50b2a28cf07
Author: Antonio Quartulli <antonio(a)open-mesh.com>
Date: Sat Nov 16 12:03:47 2013 +0100
batman-adv: add isolation_mark sysfs attribute
This attribute can be used to set and read the value and the
mask of the skb mark which will be used to classify the
source non-mesh client as ISOLATED. In this way a client can
be advertised as such and the mark can potentially be
restored at the receiving node before delivering the skb.
This can be helpful for creating network wide netfilter
policies.
This sysfs file expects a string of the shape "$mark/$mask".
Where $mark has to be a 32-bit number in any base, while
$mask must be a 32bit mask expressed in hex base. Only bits
in $mark covered by the bitmask are really stored.

batman-adv: remove FSF address from GPL disclaimer
As suggested by checkpatch, remove all the references to the
FSF address since the kernel already has one reference in
its documentation.
In this way it is easier to update it in case of future
changes.

+ * for specific protocols e.g. TCP/UDP/SCTP, then, for such packets it will

+ * undefined in this case though. It is a bad option, but, unfortunately,
+ * nowadays most vendors do this. Apparently with the secret goal to sell
+ * you new devices, when you will add new protocol to your host, f.e. IPv6 8)
+ *
+ * CHECKSUM_COMPLETE:
+ *
+ * This is the most generic way. The device supplied checksum of the _whole_
+ * packet as seen by netif_rx() and fills out in skb->csum. Meaning, the
+ * hardware doesn't need to parse L3/L4 headers to implement this.
+ *
+ * Note: Even if device supports only some protocols, but is able to produce
+ * skb->csum, it MUST use CHECKSUM_COMPLETE, not CHECKSUM_UNNECESSARY.
+ *
+ * CHECKSUM_PARTIAL:
+ *
+ * This is identical to the case for output below. This may occur on a packet
+ * received directly from another Linux OS, e.g., a virtualized Linux kernel
+ * on the same host. The packet can be treated in the same way as
+ * CHECKSUM_UNNECESSARY, except that on output (i.e., forwarding) the
+ * checksum must be filled in by the OS or the hardware.
+ *
+ * B. Checksumming on output.
+ *
+ * CHECKSUM_NONE:
+ *
+ * The skb was already checksummed by the protocol, or a checksum is not
+ * required.
+ *
+ * CHECKSUM_PARTIAL:
+ *
+ * The device is required to checksum the packet as seen by hard_start_xmit()
+ * from skb->csum_start up to the end, and to record/write the checksum at
+ * offset skb->csum_start + skb->csum_offset.
+ *
+ * The device must show its capabilities in dev->features, set up at device
+ * setup time, e.g. netdev_features.h:
+ *
+ * NETIF_F_HW_CSUM - It's a clever device, it's able to checksum everything.
+ * NETIF_F_IP_CSUM - Device is dumb, it's able to checksum only TCP/UDP over
+ * IPv4. Sigh. Vendors like this way for an unknown reason.
+ * Though, see comment above about CHECKSUM_UNNECESSARY. 8)
+ * NETIF_F_IPV6_CSUM - About as dumb as the last one but does IPv6 instead.
+ * NETIF_F_... - Well, you get the picture.
+ *
+ * CHECKSUM_UNNECESSARY:
+ *
+ * Normally, the device will do per protocol specific checksumming. Protocol
+ * implementations that do not want the NIC to perform the checksum
+ * calculation should use this flag in their outgoing skbs.

batman-adv: clean nf state when removing protocol header
If an interface enslaved into batman-adv is a bridge (or a
virtual interface built on top of a bridge) the nf_bridge
member of the skbs reaching the soft-interface is filled
with the state about "netfilter bridge" operations.
Then, if one of such skbs is locally delivered, the nf_bridge
member should be cleaned up to avoid that the old state
could mess up with other "netfilter bridge" operations when
entering a second bridge.
This is needed because batman-adv is an encapsulation
protocol.
However at the moment skb->nf_bridge is not released at all
leading to bogus "netfilter bridge" behaviours.
Fix this by cleaning the netfilter state of the skb before
it gets delivered to the upper layer in interface_rx().

batman-adv: fix vlan header access
When batadv_get_vid() is invoked in interface_rx() the
batman-adv header has already been removed, therefore
the header_len argument has to be 0.
