batman-adv: Add required includes to all files

2015-06-07T15:07:19+00:00

The header files could not be build indepdent from each other. This is happened because headers didn't include the files for things they've used. This was problematic because the success of a build depended on the knowledge about the right order of local includes. Also source files were not including everything they've used explicitly. Instead they required that transitive includes are always stable. This is problematic because some transitive includes are not obvious, depend on config settings and may not be stable in the future. The order for include blocks are: * primary headers (main.h and the *.h file of a *.c file) * global linux headers * required local headers * extra forward declarations for pointers in function/struct declarations The only exceptions are linux/bitops.h and linux/if_ether.h in packet.h. This header file is shared with userspace applications like batctl and must therefore build together with userspace applications. The header linux/bitops.h is not part of the uapi headers and linux/if_ether.h conflicts with the musl implementation of netinet/if_ether.h. The maintainers rejected the use of __KERNEL__ preprocessor checks and thus these two headers are only in main.h. All files using packet.h first have to include main.h to work correctly.

batman-adv: Modified forwarding behaviour for multicast packets

2014-03-22T08:18:57+00:00

With this patch a multicast packet is not always simply flooded anymore, the behaviour for the following cases is changed to reduce unnecessary overhead: If all nodes within the horizon of a certain node have signalized multicast listener announcement capability then an IPv6 multicast packet with a destination of IPv6 link-local scope (excluding ff02::1) coming from the upstream of this node... * ...is dropped if there is no according multicast listener in the translation table, * ...is forwarded via unicast if there is a single node with interested multicast listeners * ...and otherwise still gets flooded.

batman-adv: add kerneldoc for dst_hint argument

2014-03-22T07:50:26+00:00

Some helper functions used along the TX path have now a new "dst_hint" argument but the kerneldoc was missing. Signed-off-by: Antonio Quartulli Signed-off-by: Marek Lindner

batman-adv: send every DHCP packet as bat-unicast

2014-01-08T19:49:42+00:00

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.

batman-adv: remove FSF address from GPL disclaimer

2014-01-08T19:49:39+00:00

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. Signed-off-by: Antonio Quartulli Signed-off-by: Marek Lindner

batman-adv: refine API calls for unicast transmissions of SKBs

2013-10-19T15:31:54+00:00

With this patch the functions batadv_send_skb_unicast() and batadv_send_skb_unicast_4addr() are further refined into batadv_send_skb_via_tt(), batadv_send_skb_via_tt_4addr() and batadv_send_skb_via_gw(). This way we avoid any "guessing" about where to send a packet in the unicast forwarding methods and let the callers decide. This is going to be useful for the upcoming multicast related patches in particular. Further, the return values were polished a little to use the more appropriate NET_XMIT_* defines.

batman-adv: add the VLAN ID attribute to the TT entry

2013-10-19T13:11:21+00:00

To make the translation table code VLAN-aware, each entry must carry the VLAN ID which it belongs to. This patch adds such attribute to the related TT structures. Signed-off-by: Antonio Quartulli Signed-off-by: Marek Lindner

batman-adv: Remove old fragmentation code

2013-10-12T09:58:33+00:00

Remove the existing fragmentation code before adding the new version and delete unicast.{h,c}. batadv_unicast_send_skb() is moved to send.c and renamed to batadv_send_skb_unicast(). fragmentation entry in sysfs (bat_priv->fragmentation) is kept for use in the new fragmentation code. BATADV_UNICAST_FRAG packet type is renamed to BATADV_FRAG for use in the new fragmentation code. Signed-off-by: Martin Hundebøll Signed-off-by: Marek Lindner Signed-off-by: Antonio Quartulli
