* batman-adv: Convert packet.h to uapi headerSven Eckelmann2017-12-211-2/+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.

| | | | | | | | | | | The documentation describing kernel-doc comments for functions ("How to format kernel-doc comments") uses parentheses at the end of the function name.

| | | | | | | | | | | | | | | 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.

With some carefully placed msleep()s/mdelay()s it can be reproduced easily. The issue is, that on interface removal, any still running worker thread of a forwarding packet will race with the interface purging routine to free a forwarding packet. Temporarily giving up a spin-lock to be able to sleep in the purging routine is not safe. Furthermore, there is a potential general protection fault not just for the purging side shown above, but also on the worker side: Temporarily removing a forw_packet from the according forw_{bcast,bat}_list will make it impossible for the purging routine to catch and cancel it. # How this patch tries to fix it: With this patch we split the queue purging into three steps: Step 1), removing forward packets from the queue of an interface and by that claim it as our responsibility to free. Step 2), we are either lucky to cancel a pending worker before it starts to run. Or if it is already running, we wait and let it do its thing, except two things: Through the claiming in step 1) we prevent workers from a) re-arming themselves. And b) prevent workers from freeing packets which we still hold in the interface purging routine. Finally, step 3, we are sure that no forwarding packets are pending or even running anymore on the interface to remove. We can then safely free the claimed forwarding packets.

* batman-adv: Simple (re)broadcast avoidanceLinus Lüssing2016-10-301-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | With this patch, (re)broadcasting on a specific interfaces is avoided: * No neighbor: There is no need to broadcast on an interface if there is no node behind it. * Single neighbor is source: If there is just one neighbor on an interface and if this neighbor is the one we actually got this broadcast packet from, then we do not need to echo it back. * Single neighbor is originator: If there is just one neighbor on an interface and if this neighbor is the originator of this broadcast packet, then we do not need to echo it back. Goodies for BATMAN V: ("Upgrade your BATMAN IV network to V now to get these for free!") Thanks to the split of OGMv1 into two packet types, OGMv2 and ELP that is, we can now apply the same optimizations stated above to OGMv2 packets, too. Furthermore, with BATMAN V, rebroadcasts can be reduced in certain multi interface cases, too, where BATMAN IV cannot. This is thanks to the removal of the "secondary interface originator" concept in BATMAN V.

* batman-adv: keep track of when unicast packets are sentAntonio Quartulli2016-02-291-3/+7
| | | | | | | | | | | | | | | | | | | | To enable ELP to send probing packets over wireless links only if needed, batman-adv must keep track of the last time it sent a unicast packet towards every neighbour. For this purpose a 2 main changes are introduced: 1) a new member of the elp_neigh_node structure stores the last time a unicast packet was sent towards this neighbour; 2) a wrapper function for sending unicast packets is implemented. This function will simply update the member describe din point 1) and then forward the packet to the real sending routine. Point 2) implies that any code-path leading to a unicast sending now has to use the new wrapper.

* batman-adv: Add required includes to all filesSven Eckelmann2015-06-071-0/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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: send every DHCP packet as bat-unicastAntonio Quartulli2014-01-081-4/+6
| | | | | | | | | | | | | | | | | | | 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.

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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The client announcement mechanism informs every mesh node in the network of any connected non-mesh client, in order to find the path towards that client from any given point in the mesh. The old implementation was based on the simple idea of appending a data buffer to each OGM containing all the client MAC addresses the node is serving. All other nodes can populate their global translation tables (table which links client MAC addresses to node addresses) using this MAC address buffer and linking it to the node's address contained in the OGM. A node that wants to contact a client has to lookup the node the client is connected to and its address in the global translation table. It is easy to understand that this implementation suffers from several issues: - big overhead (each and every OGM contains the entire list of connected clients) - high latencies for client route updates due to long OGM trip time and OGM losses The new implementation addresses these issues by appending client changes (new client joined or a client left) to the OGM instead of filling it with all the client addresses each time. In this way nodes can modify their global tables by means of "updates", thus reducing the overhead within the OGMs. To keep the entire network in sync each node maintains a translation table version number (ttvn) and a translation table checksum. These values are spread with the OGM to allow all the network participants to determine whether or not they need to update their translation table information. When a translation table lookup is performed in order to send a packet to a client attached to another node, the destination's ttvn is added to the payload packet. Forwarding nodes can compare the packet's ttvn with their destination's ttvn (this node could have a fresher information than the source) and re-route the packet if necessary. This greatly reduces the packet loss of clients roaming from one AP to the next.
