* batman-adv: no need to check return value of debugfs_create functionsGreg Kroah-Hartman2019-06-271-1/+1
| | | | | | | | | | | | | | | | | | | | | When calling debugfs functions, there is no need to ever check the return value. The function can work or not, but the code logic should never do something different based on this. Because we don't care if debugfs works or not, this trickles back a bit so we can clean things up by making some functions return void instead of an error value that is never going to fail.

* batman-adv: Use includes instead of fwdeclsSven Eckelmann2019-05-251-2/+1
| | | | | | | | | | | | While it can be slightly beneficial for the build performance to use forward declarations instead of includes, the handling of them together with changes in the included headers makes it unnecessary complicated and fragile. Just replace them with actual includes since some parts (hwmon, ..) of the kernel even request avoidance of forward declarations and net/ is mostly not using them in *.c file.

* batman-adv: Add SPDX license identifier above copyright headerSven Eckelmann2017-12-151-0/+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.

* batman-adv: Allow to disable debugfs supportSven Eckelmann2016-08-091-1/+17
| | | | | | | | | | | | | | | | | | The files provided by batman-adv via debugfs are currently converted to netlink. Tools which are not yet converted to use the netlink interface may still rely on the old debugfs files. But systems which already upgraded their tools can save some space by disabling this feature. The default configuration of batman-adv on amd64 can reduce the size of the module by around 11% when this feature is disabled. $ size net/batman-adv/batman-adv.ko* text data bss dec hex filename 150507 10395 4160 165062 284c6 net/batman-adv/batman-adv.ko.y 137106 7099 2112 146317 23b8d net/batman-adv/batman-adv.ko.n Signed-off-by: Sven Eckelmann <sven@narfation.org> Signed-off-by: Marek Lindner <mareklindner@neomailbox.ch> Signed-off-by: Simon Wunderlich <sw@simonwunderlich.de>

* batman-adv: Add required includes to all filesSven Eckelmann2015-06-071-0/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 FSF address from GPL disclaimerAntonio Quartulli2014-01-081-3/+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>
* batman-adv: generalize batman-adv icmp packet handlingSimon Wunderlich2013-10-231-1/+1
| | | | | | | | | | | | | | | | Instead of handling icmp packets only up to length of icmp_packet_rr, the code should handle any icmp length size. Therefore the length truncating is moved to when the packet is actually sent to userspace (this does not support lengths longer than icmp_packet_rr yet). Longer packets are forwarded without truncating. This patch also cleans up some parts where the icmp header struct could be used instead of other icmp_packet(_rr) structs to make the code more readable.

* batman-adv: Prefix icmp-socket non-static functions with batadv_Sven Eckelmann2012-06-201-4/+4
| | | | | | | | | | | batman-adv can be compiled as part of the kernel instead of an module. In that case the linker will see all non-static symbols of batman-adv and all other non-static symbols of the kernel. This could lead to symbol collisions. A prefix for the batman-adv symbols that defines their private namespace avoids such a problem. Reported-by: David Miller <davem@davemloft.net> Signed-off-by: Sven Eckelmann <sven@narfation.org>
