2018-03-14batman-adv: add DAT cache netlink supportLinus Lüssing1-0/+8

2017-12-21batman-adv: Convert packet.h to uapi headerSven Eckelmann1-1/+1
The header file is used by different userspace programs to inject packets or to decode sniffed packets. It should therefore be available to them as userspace header. Also other components in the kernel (like the flow dissector) require access to the packet definitions to be able to decode ETH_P_BATMAN ethernet packets.

2017-12-15batman-adv: Use parentheses in function kernel-docSven Eckelmann1-3/+3
The documentation describing kernel-doc comments for functions ("How to format kernel-doc comments") uses parentheses at the end of the function name. Using this format allows to use a consistent style when adding documentation to a function and when referencing this function in a different kernel-doc section.

2017-12-15batman-adv: Add SPDX license identifier above copyright headerSven Eckelmann1-0/+1
The "Linux kernel licensing rules" require that each file has a SPDX license identifier as first line (and sometimes as second line). The FSFE REUSE practices [1] would also require the same tags but have no restrictions on the placement in the source file. Using the "Linux kernel licensing rules" is therefore also fulfilling the FSFE REUSE practices requirements at the same time.

2015-08-25batman-adv: Replace C99 int types with kernel typeSven Eckelmann1-4/+4
(s|u)(8|16|32|64) are the preferred types in the kernel. The use of the standard C99 types u?int(8|16|32|64)_t are objected by some people and even checkpatch now warns about using them.

2015-06-07batman-adv: Add required includes to all filesSven Eckelmann1-3/+10
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.

2014-01-08batman-adv: remove FSF address from GPL disclaimerAntonio Quartulli1-3/+1
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 <antonio@meshcoding.com> Signed-off-by: Marek Lindner <mareklindner@neomailbox.ch>

2012-11-07batman-adv: Distributed ARP Table - add compile optionAntonio Quartulli1-0/+65
This patch makes it possible to decide whether to include DAT within the batman-adv binary or not. It is extremely useful when the user wants to reduce the size of the resulting module by cutting off any not needed feature. Signed-off-by: Antonio Quartulli <ordex@autistici.org>
2012-11-07batman-adv: Distributed ARP Table - add snooping functions for ARP messagesAntonio Quartulli1-0/+11
In case of an ARP message going in or out the soft_iface, it is intercepted and a special action is performed. In particular the DHT helper functions previously implemented are used to store all the ARP entries belonging to the network in order to provide a fast and unicast lookup instead of the classic broadcast flooding mechanism. Each node stores the entries it is responsible for (following the DHT rules) in its soft_iface ARP table. This makes it possible to reuse the kernel data structures and functions for ARP management.

2012-11-07batman-adv: Distributed ARP Table - add ARP parsing functionsAntonio Quartulli1-0/+2
ARP messages are now parsed to make it possible to trigger special actions depending on their types (snooping). Signed-off-by: Antonio Quartulli <ordex@autistici.org>
2012-11-07batman-adv: Distributed ARP Table - implement local storageAntonio Quartulli1-0/+4
Since batman-adv cannot inter-operate with the host ARP table, this patch introduces a batman-adv private storage for ARP entries exchanged within DAT. This storage will represent the node local cache in the DAT protocol. Signed-off-by: Antonio Quartulli <ordex@autistici.org>
2012-11-07batman-adv: Distributed ARP Table - create DHT helper functionsAntonio Quartulli1-0/+58
Add all the relevant functions in order to manage a Distributed Hash Table over the B.A.T.M.A.N.-adv network. It will later be used to store several ARP entries and implement DAT (Distributed ARP Table) Signed-off-by: Antonio Quartulli <ordex@autistici.org>
