batman-adv: Remove batadv_ types forward declarations

2015-08-24T22:12:20+00:00

main.h is included in every file and is the only way to access types.h.
This makes forward declarations for all types defined in types.h
unnecessary.

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: remove returns at the end of void functions

2014-01-12T13:41:18+00:00

Return at the end of void functions is not needed.

Since most of the void functions in the code do not do so,
make all the others consistent by removing the useless
returns. Actually all the functions to be "fixed" are in
network-coding.h only.

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.

batman-adv: set up network coding packet handlers during module init

2013-10-02T11:46:19+00:00

batman-adv saves its table of packet handlers as a global state, so handlers
must be set up only once (and setting them up a second time will fail).

The recently-added network coding support tries to set up its handler each time
a new softif is registered, which obviously fails when more that one softif is
used (and in consequence, the softif creation fails).

Fix this by splitting up batadv_nc_init into batadv_nc_init (which is called
only once) and batadv_nc_mesh_init (which is called for each softif); in
addition batadv_nc_free is renamed to batadv_nc_mesh_free to keep naming
consistent.

batman-adv: Move call to batadv_nc_skb_forward() from routing.c to send.c

2013-05-29T00:44:55+00:00

The call to batadv_nc_skb_forward() fits better in
batadv_send_skb_to_orig(), as this is where the actual next hop is
looked up.

To let the caller of batadv_send_skb_to_orig() know wether the skb is
transmitted, buffered or failed, the return value is changed from
boolean to int.

batman-adv: network coding - save overheard and tx packets for decoding

2013-03-13T21:53:50+00:00

To be able to decode a network coded packet, a node must already know
one of the two coded packets. This is done by buffering skbs before
transmission and buffering packets sniffed with promiscuous mode from
other hosts.

Packets are kept in a buffer similar to the one with forward-skbs: A
hash table, where each entry, which corresponds to a src-dst pair, has a
linked list packets.
